Responding to a new security incident in the fastest possible time frame is critical for any security operations center (SOC) or computer security incident response team (CSIRT), but having the necessary information at your fingertips is key in order to help improve response times and appropriately deal with the threat at hand. In this blog post we’ll take a closer look at how security teams can increase the efficiency and effectiveness of their response by adding context and enrichment to the alert information directly from ArcSight, when utilizing DFLabs’ Security Orchestration, Automation and Response (SOAR) platform and its many other bidirectional integrations.
Organizations are generating more log data than ever before and are increasingly turning to SIEM tools to help manage, correlate and alert on potential events from this large quantity of data. Once data is correlated and an alert is generated, enriching alert data is often a manual task which consumes a significant amount of analysts’ time. Pivoting from a single alert or from enriched information is often also a manual process, requiring many more custom written queries within the SIEM. Enriched and additional data must then be correlated manually by the analyst before it becomes actionable.
On a daily basis an analyst will face a number of challenges and is likely to be asking themselves the following questions:
- How can I use the SIEM logs to add context to a security event?
- How can I enrich information from the initial security alert?
- How can I pivot from the initial security alert to further my investigation?
The DFLabs and ArcSight Solution
DFLabs and MicroFocus ArcSight bring SOAR and SIEM together to allow rapid, informed responses to security incidents based on enriched, actionable information. DFLabs’ IncMan SOAR platform allows users to automatically query ArcSight to pivot from an initial alert to gather increase insight into the activity within the organization. IncMan also allows users to enrich information retrieved from ArcSight, such as IP addresses, hostnames and domains, using any number of IncMan’s other integrations.
About MicroFocus ArcSight
ArcSight is an industry-leading Security Information and Event Management (SIEM) solution from MicroFocus. ArcSight collects and analyzes events from across systems and security tools. It detects security threats in real time so that analysts respond quickly, and it scales to meet demanding security requirements. ArcSight’s advanced distributed correlation engine, helps security teams detect and respond to internal and external threats, reduces response time from hours or days to just minutes.
To get a real understanding of how the two solutions work together, here is a simple use case in action.
A Web Application Firewall (WAF) has observed a potential attack against an application server in the organization’s DMZ. IncMan automatically responds by initiating an appropriate runbook for the alert. The runbook begins by performing basic enrichment on the source IP address of the malicious traffic. This basic enrichment is followed by a query for IP reputation information on the source IP address from the organization’s threat reputation service of choice.
Following the threat reputation search, ArcSight is queried for any other events which have been recently generated by the source IP address. If ArcSight returns any other recent events generated by the source IP address, or the source IP address has a negative threat reputation, the severity of the incident is automatically upgraded to High. The analyst is then presented with a user choice decision to determine if the source IP address should be blocked at the perimeter firewall. If the analyst chooses to automatically block the source IP address, a ticket will be created in ArcSight Enterprise Security Manager (ESM) to notify the appropriate teams to follow up on the emergency change according to the organization’s policies.
These actions are followed by a second query to ArcSight, this time for any other recent events involving the web application server. If ArcSight returns any other recent events generated from the web application server, the severity of the incident is automatically upgraded to High (unless it has already previously been upgraded). The runbook concludes by performing a query of the organization’s endpoint detection solution for all recent events from the web application server. This information will be retained for review by the analyst during the investigative process.
In summary, here are the actions available to security analysts by using ArcSight.
- Get Active List Entries
- Search Into Events
- Add Active List Entries
- Clean Active List Entries
- Create Ticket
- Get Ticket
- Update Ticket
Integrating ArcSight with DFLabs’ IncMan SOAR allows organizations to efficiently triage the volume of alerts being generated by the SIEM, automatically prioritizing those alerts which may pose the greatest risk to the organization. By automating and orchestrating the SIEM with other security solutions, IncMan SOAR can automatically enrich the alert information, then pivot based on the enriched information as an analyst would do during a manual investigation. This ability to automatically enrich and pivot allows IncMan to more accurately prioritize incidents which may initially seem innocuous.
As soon as the first indicator of compromise is located, the most common next step is to try to pivot from that indicator to find additional indicators or evidence on the network. While it is sometimes necessary to perform your own research to determine what additional additional indicators may be present, it is common to make use of previous research when looking for new indicators to hunt for.
This is especially true when dealing with an indicator of malicious software. Perhaps you have found a host communicating with an IP address known to be associated with a particular malware variant; the logical next step would be to search for communication with other IPs, domains and URLs the malware may be associated with, along with looking for the host-based activity the malware is known to use.
For example, suppose an IDS alerted on the IP address 144.202.87[.]106. A quick search on VirusTotal indicates that this IP address may be malicious, however, it does not provide much information which could be used to pivot to other indicators. So where does every good analyst turn at this point? Google, of course! A quick Google search for the IP address returns several results, including a blog post from MalwareBytes on the Hidden Bee miner.
Along with a detailed analysis of the Hidden Bee miner, the post also includes several other IP addresses and URLs which analysts observed in this attack. Now we have some data to pivot and hunt with!
This entire analysis from the MalwareBytes team can easily be added into DFLabs’ IncMan SOAR platform by copying and pasting the blog into the Additional Info section of the incident. In addition to allowing this information to be accessed by the working on this incident, adding this text to the Additional Info field has an additional advantage we have not yet discussed; Automatic Observable Harvesting.
When text is added to a field such as the Additional Info fields in IncMan, Automatic Observable Harvesting will automatically parse through the text and attempt to harvest observables from the unstructured text.
In the case of the Hidden Bee analysis from MalwareBytes, Automatic Observable Harvesting automatically harvested four IP addresses, a URL and a domain from the unstructured text and added them to the observables section.
While six observables may not take long to manually enter into the platform, it is not uncommon to find detailed malware analysis that contains dozens of IP addresses, hash values, domains, and other observables. Entering this many observables into IncMan manually in order to take advantage of IncMan’s automation and orchestration features on the new observables would be a time-consuming process. Automatic Observable Harvesting performs this task automatically.
Once these new observables are added into IncMan, analysts can take advantage of IncMan’s automation and orchestration features to begin performing additional enrichment on the observables, as well as searching across any internal data sources for evidence of the observables and blocking them if needed.
We’ve been witnessing the continual transformation of the cyber security ecosystem in the past few years. With cyber attacks becoming ever-more sophisticated, organizations have been forced to spend huge amounts of their budgets on improving their security programs in an attempt to protect their infrastructure, corporate assets, and their brand reputation from potential hackers.
Recent research, however, still shows that a large number of organizations are experiencing an alarming shortage of the cyber security skills and tools required to adequately detect and prevent the variety of attacks being faced by organizations. Protecting your organization today is a never-ending and complex process. I am sure, like me, you are regularly reading many cyber security articles and statistics detailing these alarming figures, which are becoming more of a daily reality.
Many organizations are now transitioning the majority of their efforts on implementing comprehensive incident response plans, processes and workflows to respond to potential incidents in the quickest and most efficient ways possible. But even with this new approach, many experts and organizations alike express concerns that we will still be faced with a shortage of skilled labor able to deal with these security incidents, with security teams struggling to fight back thousands of potential threats generated from incoming security alerts on a daily basis.
With so many mundane and repetitive tasks to complete, there’s little time for new strategies, planning, training, and knowledge transfer. To make things worse, security teams are spending far too much of their valuable time reacting to the increasing numbers of false positives, to threats that aren’t real. This results in spending hours, even days on analyzing and investigating false positives, which leaves little time for the team to focus on mitigating real, legitimate cyber threats, which could result in a serious and potentially damaging security incident. Essentially, we need to enable security operations teams to work smarter, not harder; but is this easier said than done?
How does security orchestration and automation help security teams?
With this in mind, organizations need to find new ways combat these issues, while at the same time add value to their existing security program and tools and technologies being used, to improve their overall security operations performance. The answer is in the use of Security Orchestration, Automation and Response (SOAR) technology.
Security Orchestration, Automation, and Response SOAR solutions focus on the following core functions of security operations and incident response and help security operations centers (SOCs), computer security incident response teams (CSIRTs) and managed security service providers (MSSPs) work smarter and act faster:
- Orchestration – Enables security operations to connect and coordinate complex workflows, tools and technologies, with flexible SOAR solutions supporting a vast number of integrations and APIs.
- Automation – Speeds up the entire workflow by executing actions across infrastructures in seconds, instead of hours if tasks are performed manually.
- Collaboration – Promotes more efficient communication and knowledge transfer across security teams
- Incident Management – Activities and information from a single incident are managed within a single, comprehensive platform, allowing tactical and strategic decision makers alike complete oversight of the incident management process.
- Dashboards and Reporting: Combines of core information to provide a holistic view of the organization’s security infrastructure also providing detailed information for any incident, event or case when it is required by different levels of stakeholders.
Now let’s focus on the details of these core functions and see how they improve the overall performance.
Security Orchestration is the capacity to coordinate, formalize, and automate responsive actions upon measuring risk posture and the state of affairs in the environment; more precisely, it’s the fashion in which disparate security systems are connected together to deliver larger visibility and enable automated responses; it also coordinates volumes of alert data into workflows.
With automation, multiple tasks on partial or full elements of the security process can be executed without the need for human intervention. Security operations can create sophisticated processes with automation, which can improve accuracy. While the concepts behind both security orchestration and automation are somewhat related, their aims are quite different. Automation aims to reduce the time processes take, making them more effective and efficient by automating repeatable processes and tasks. Some SOAR solutions also applying machine learning to recommend actions based on the responses to previous incidents. Automation also aims to reduce the number of mundane actions that must be completed manually by security analysts, allowing them to focus on a high level and more important actions that require human intervention.
Incident Management and Collaboration
Incident management and collaboration consist of the following activities:
- Alert processing and triage
- Journaling and evidentiary support
- Analytics and incident investigation
- Threat intelligence management
- Case and event management, and workflow
Security orchestration and automation tools are designed to facilitate all of these processes, while at the same making the process of threat identification, investigation and management significantly easier for the entire security operations team.
Dashboards and Reporting
SOAR tools generate reports and dashboards for a range of stakeholders from the day to day analysts, SOC managers, other organization departments and even C-level executives. These dashboards and reports are not only used to provide security intelligence, but they can also be used to develop analyst skills.
Human Factor Still Paramount
Security orchestration and automation solutions create a more focused and streamlined approach and methodology for detection and response to cyber threats by integrating the company’s security capacity and resources with existing experts and processes in order to automate manual tasks, orchestrate processes and workflows, and create an overall faster and more effective incident response.
Whichever security orchestration and automation solution a company chooses, it is important to remember that no one single miracle solution guarantees full protection. Human skills remain the core of every future security undertaking and the use of security orchestration and automation should not be viewed as a total replacement of a security team. Rather, it should be considered a supplement that enables the security team by easing the workload, alleviating the repetitive, time-consuming tasks, formalizing processes and workflows, while supporting and empowering the existing security team to turn into proactive threat hunters as opposed to reactive incident investigators.
Humans and machines combined can work wonders for the overall performance of an organization’s security program and in the long run allows the experts in the team to customize and tailor their actions to suit the specific business needs of the company.
Finally, by investing in a SOAR solution for threat detection and incident response, organizations can increase their capacity to detect, respond to and remediate all security incidents and alerts they are faced with in the quickest possible time frames.
Discussions about security breaches often focus on the planning elements, but simply talking about planning is not enough. Comprehensive plans need to be drawn up, fully executed and regularly reviewed in order to be successful. This is the only way to potentially contain the breach and limit the impact it could have on the organization. Properly planning and implementing is the difference between success and failure for companies when it comes to security and incident response.
As the ever-evolving cyber security landscape poses new challenges, companies are pushed even more to fight back the growing number and even more sophisticated levels of cyber attacks. Organizations across all sectors and industries are potential targets and could become victims at any time. With attacks escalating in all areas, whether via phishing or malware, for example, security operations teams need to be prepared to respond to existing and new types and strains of threats, in order to fully defend and protect their company assets and networks.
Along with prevention becoming increasingly difficult for security teams, some organizations also tend to have a weakness when it comes to incident response. Below outlines some of the main reasons why this failure is happening today and if this a true representation of your organization, it is important for action to be taken in order to improve it.
With the number of sophisticated cyber threats in the past several years growing at a phenomenal rate, the security industry has been facing an explosion of security tools available in the market. Many of these though have adversely resulted in creating more tasks for security teams and analysts in terms of monitoring, correlating, and responding to alerts. Analysts are pushed to work on multiple platforms and generate data from every single source manually, while afterwards then needing to enrich and correlate that data which can take many hours or even days.
Security budgets are often limited, and while it is often easier to gain support and approval for additional security apps and tools than it is for additional staff members, this means that many security teams often are forced to search innovative ways to perform many different tasks with extremely limited personnel resources.
Another important point to note is that with increased market competition for experienced and skilled analysts, companies are often forced to choose between hiring one highly skilled staff member versus a couple of less experienced, junior level ones.
Over the years, organizations have witnessed an increasing number of security tools to fight back the growing number of security threats. But even though these tools manage alerts and correlate through security information and management system, security teams are still overwhelmed by the volume of alerts being generated and in many instances are not physically able to respond to them all.
Every single alert must be verified manually and triaged by an analyst. Then, if the alert is determined to be valid, additional manual research and enrichment must take place before any other action to address the threat. While all of these processes take place, other potential alerts wait unresolved in a queue, while new alerts keep being added. The problem is, any one of these alerts may be an opportunity window for an attacker while they wait to be addressed.
Risk of Losing Skilled Analysts
Security processes are performed manually and are quite complex in nature, therefore training new staff members takes time. Organizations still rely on the most experienced analysts when it comes to decision making, based on their knowledge and work experience in the company, even with documented procedures in place. This is commonly referred to as tribal knowledge, and the more manual the processes are, the longer the knowledge transfer takes. Moreover, highly qualified analysts are considered a real treasure for the company, and every time a company loses such staff member, part of the tribal knowledge is also lost, and the entire incident response process suffers a tremendous loss. Even though companies make efforts to keep at least one skilled analyst who is able to teach other staff members the skills they have, they aren’t always successful in that.
Failure to Manage Phases
Security teams work with metrics that could be highly subjective and abstract, compared to other departments which often work with proven processes for measuring the effectiveness or ineffectiveness of a program. This is largely due to the fact that conservative approaches and methods for measuring ROI aren’t applicable, nor appropriate when it comes to security projects, and might give misleading results. Proper measurement techniques are of utmost importance when it comes to measuring the effectiveness and efficiency of a security program, therefore it is necessary to come up with a measurement process customized according to the needs of the company.
Another important issue that should be mentioned here is the one concerning the management of different steps of the incident response process. Security incidents are very dynamic processes that involve different phases, and the inability to manage these steps could result in great losses and damages to the company. For the best results, companies should focus on implementing documented and repeatable processes that have been tested and well understood.
In order to resolve these issues, organizations should consider the following best practices.
The coordination of security data sources and security tools in a single seamless process is referred to as orchestration. Technology integrations are most often used to support the orchestration process. APIs, software development kits, or direct database connections are just a few of the numerous methods that can be used to integrate technologies such as endpoint detection and response, threat intelligence, network detection, and infrastructure, IT service and account management.
Orchestration and automation might be related, but their end goals are completely different. Orchestration aims to improve efficiency by increased coordination and decreased context switch among tools for a faster and better-informed decision-making, while automation aims to reduce the time these processes take and make them repeatable by applying machine learning to respective tasks. Ideally, automation increases the efficiency of orchestrated processes.
Strategic and Tactical Measurement
Information in favor of tactical decisions usually consists of incident data for analysts and managers, which might consist of indicators of compromise assets, process status, and threat intelligence. This information improves decision-making from incident triage and investigation, through containment and eradication.
On the other hand, strategic information is aimed at executives and managers, and it’s used for high-level decision making. This information might comprise statistics and incident trends, threat intelligence and incident correlation. Advanced security programs might also use strategic information to enable proactive threat hunting.

In security, information is power. Having actionable information available at the touch of a button can be the difference between stopping a threat in its tracks and becoming the victim of the next big breach. However, the many disparate security products deployed in most organizations make information sharing and integration difficult, if not impossible.
Lack of information sharing and integrations between security products leads to a time consuming and disjointed response to a security incident; an environment ripe for mistakes to be made.
Information sharing and security product integration and orchestration have always been at the core of the many values provided by DFLabs. By designing a solution that is OpenDXL compatible, DFLabs has provided joint DFLabs and McAfee customers with yet another way to streamline their security processes.
DFLabs IncMan SOAR and McAfee OpenDXL solve these specific challenges:
- How can I share security information between my security products?
- How can I quickly integrate my security products without the need for time-consuming custom integrations?
McAfee’s OpenDXL allows compatible security applications to seamlessly share security information without the need for complicated custom integrations. DFLabs IncMan OpenDXL implementation is now certified as McAfee compatible. All integrations between DFLabs IncMan platform and McAfee, including ePO, ATD and TIE, have been enhanced to include OpenDXL, significantly reducing the complexity gathering actionable enrichment information from these solutions.
OpenDXL lets developers join an adaptive system of interconnected services that communicate and share information to make real-time accurate security decisions. OpenDXL leverages the Data Exchange Layer (DXL), which many vendors and enterprises already utilize, and delivers a simple, open path for integrating security technologies regardless of vendor.
Together, this integration enables the ability to share information seamlessly between IncMan SOAR and McAfee products using OpenDXL, which leverages the power of OpenDXL for easy to use, feature rich integrations between products.
One of the most common and versatile use cases for OpenDXL within IncMan is integration with McAfee Threat Intelligence Exchange (TIE). McAfee TIE is a reputation broker which combines threat intelligence from imported global sources, such as McAfee Global Threat Intelligence (McAfee GTI) and third-party threat information (such as VirusTotal) with intelligence from local sources, including endpoints, gateways, and advanced analysis solutions. Using Data Exchange Layer (DXL), it instantly shares this collective intelligence across your security ecosystem, allowing security solutions to operate as one to enhance protection throughout the organization.
McAfee TIE makes it possible for administrators to easily tailor threat intelligence. Security administrators are empowered to assemble, override, augment, and tune the comprehensive intelligence information to customize protection for their environment and organization. This locally prioritized and tuned threat information provides instant response to any future encounters. Threat intelligence from McAfee TIE can be used to enrich indicators, such as file hashes, using IncMan’s R3 Rapid Response Runbooks to enable intelligent automated or manual decisions during the incident response process.
DFLabs IncMan also integrates with other McAfee tools. You can learn more about our integration with McAfee ATD and ePO in our previous blog posts.
While many institutions and businesses from various industries were still reeling from the WannaCry attack that took the world by storm back in May, cyber criminals launched another crippling ransomware attack earlier this week, catching a lot of cyber security professionals across 60 countries by surprise and bringing essential business operations to a halt.This latest high-profile attack, called Petya ransomware, bears many of the hallmarks of WannaCry, in that it is a typical ransomware scheme, paralyzing computers and spreading through internal networks after infecting one machine.
Another important similarity is that just like WannaCry, Petya exploited the same Microsoft Windows vulnerability – Eternal Blue, to spread within networks. On the other hand, there is one significant difference between the two attacks – Petya, unlike WannaCry, was not aimed at extorting money, but rather incurring serious damage to computer networks, with researchers saying that Petya was just disguised as ransomware, but its main goal was to spread throughout networks as fast as possible and cause the biggest infrastructural damages possible.
Containing the Damage
Petya ransomware was primarily designed to infect computers in order to prevent organizations from continuing their day-to-day operations, rather than gaining financial benefit, and the attack did affect business operations of many companies, inflicting severe financial and reputation damage upon them. Ransomware attacks are extremely difficult to prevent, and the best thing organizations can do to avoid serious long-term consequences in case they get hit by one, is to make sure they have the tools to respond to it and contain the damage as fast as possible.
That can be best done with the help of an incident response platform with automation and orchestration capabilities. These types of platforms can help security teams reduce their reaction time when responding to an incident, which is crucial when attacks such as Petya occur. With a set of playbook actions specific to ransomware attacks, an incident response platform will allow your team to detect and analyze the attack faster, and it will suggest a specific list of actions that can help contain the damage in the most effective way possible. When it comes to ransomware attacks, recommended containment actions include isolating compromised machines, blocking communication over ports, and disconnecting shared drives, among other things.
Once you have taken the suggested containment actions, the platform will help you accelerate the recovery and remediation processes, and perform the appropriate post-incident procedure. The post-incident reactions are particularly important when dealing with ransomware attacks, as they play a major role in ensuring compliance with breach notification rules covering these types of cybersecurity incidents, such as the HIPAA Breach Notification Rule in the US.
To conclude, even though preventing ransomware attacks is a major challenge and there is not much that organizations can do in that regard, there are a lot of things they can do to reduce the impact of such incidents and avoid long-lasting consequences, which are usually associated with these types of cybersecurity events.
In the context of cyber security, two of the most pressing concerns facing many organizations are the ever-rising number of cyber attacks and figuring out how to keep them at bay without having to increase manpower. The recent Cyber attacks are now more sophisticated and noticeably more common than they were even just a few years ago. Faced with this increased volume, private entities and government agencies are struggling to figure out how to help their security teams respond to cyber events in an effective and timely manner, while finding that most potential solutions require either substantial financial expense, or rely on the addition of specialized human resources.
Hiring skilled staff is a real challenge for most organizations amid an acute and global cyber security skills shortage. Unmet demand has led professionals in this field to command disproportionately high salaries and made it that much more difficult for businesses and governments to attract cyber security talent. Consequently, organizations are now also forced to seek out technical solutions that might actually help decrease their reliance on specialized and expensive human resources. This is where cyber security incident response platforms come in as arguably the most convenient, practical and cost-effective solution to the growing cyber security threat issue and specialized resource shortage.
Ease the Strain on Security Teams by Automating Time Consuming Incident Response Tasks
A security automation and orchestration platform is the economical solution to enable an organization to respond to cyber threats and eradicate them in the most effective and fastest way possible. It is also the best way to ease the strain on security teams which, in many organizations, are already overwhelmed with an uninterrupted incident response workload.
Analyzing and assessing the legitimacy, impact and scope of a cyber incident are some of the most time-consuming tasks undertaken by cyber security professionals today. It is exactly within those tasks that an orchestration and automation platform can be of most service. From an incident identification and analysis perspective, these platforms are force multipliers which greatly accelerate the incident triage process. They provide an organization with the ability to analyze the cause and effect of each incident and to assess the scope and impact to an organization from any number of incidents at any given time. From a response perspective, and beyond their ability to automate response activity on existing security infrastructure, they can generate automated incident reports for distribution to in-house security teams, providing response and recovery resources with key insights into the scope and severity of an incident, thereby often dramatically reducing reaction times.
In short, the dual challenge of addressing a growing number of cyber attacks while maintaining an ability to mount an effective response within an existing cyber security team, is best tackled by employing an automation and orchestration platform. Deploying this tool as a force multiplier for both existing security infrastructure and human resources, allows security teams to offload the most intensive tasks and frees these professionals to focus on the more high-value areas of a cyber security threat response.
The greatest challenge for every organization that deals with cyber security threats is how to reduce its reaction time when responding to an incident and recover as soon as possible in order to minimize the consequences and contain the damage.
A new study that was recently published by the University of Portsmouth states that the fact that it takes a long time for organizations to recover from an incident makes them that much more vulnerable to future attacks soon thereafter. The study was conducted by researchers with the University of Portsmouth’s School of Computing, who have found that many organizations across different industries are faced with a serious issue threatening their cyber security, caused by long recovery times from cyber attacks and data breaches they had already suffered. The researchers call the recovery time between two cyber attacks increases an organization’s susceptibility to more attacks, dubbing that period “mean blind spot”.
After analyzing the VERIS Community Database – a dataset of cyber incident reports collected through various information sharing initiatives, researchers found that organizations often take days to recover from an attack, rather than hours, which increases the risk of getting breached between attacks. This suggests that reducing reaction times when responding to an incident can play an important role in preventing future cyber attacks.
Available Solutions for Reducing Reaction Times
The results of the University of Portsmouth’s study unequivocally point to the need for organizations to adopt a solution that would allow them to recover from cyber attacks much faster than today’s current speeds. Considering that there are a lot of actions that should be taken simultaneously by cyber security teams after their organization is breached, as they try to resolve the incident, a solution that would take care of some of those actions for them would be of great help to them and would accelerate the recovery process.
There are various solutions that can provide this type of help, and automation-and-orchestration cyber incident response platforms are what cyber security professionals need in their efforts for resolving incidents quickly and effectively. Those types of platforms allow you to execute a previously devised incident response plan in the most effective manner and save precious time while working on recovery.
One capability that these platforms provide that can be crucial for the mitigation of the problem at hand, is the fact that they allow you to analyze and respond to incidents in real time. They can automatically perform time-consuming tasks such as analysis of the reasons and origin of an incident, allowing you to quickly figure out where an attack is originating from and understand the methods and channels that were used by the attackers. Through automated playbooks, an incident response platform helps cyber security teams to prioritize their response, providing them with the key risk indicators so that they will know the current status of an incident and react accordingly.
Also, these platforms have the capability to create automated incident reports, run predictive analysis, and collect digital evidence for forensics purposes, which reduces reaction times even further.
In summation, the “mean blind spot” issue pointed out by the University of Portsmouth study could be best addressed by organizations by employing an incident response platform that is capable of automating some of the key processes that are part of a typical incident response plan.
The healthcare industry is under a constant threat of cyber attacks, mostly due to the fact that organizations within this sector keep a variety of confidential and pertinent information, such as credit card information, social security numbers, insurance-related information, and some believe most importantly personal medical records.
A recent report states that healthcare entities have been under increased risk of targeted attacks lately, including phishing attacks, ransomware attacks, and network hacking attacks. The heightened risk for cyber attacks points to a growing need for enhanced protection, in addition to raising awareness of the different types of cyber attacks that many healthcare organizations are facing.
Healthcare Surpasses Financial Sector as the Most Frequently Attacked Industry
According to data provided by Advisen and Hiscox, the average cost of a cyber incident in the healthcare industry cost $150,000. A recent report published by IBM states that the healthcare industry was attacked more frequently than any other sector last year, replacing the financial services sector at the top. According to the report, over 100 million healthcare records were compromised in 2015, which is a staggering figure by all standards.
The Advisen and Hiscox report also notes that there has been a 1.6-times increase in Health Insurance Portability and Accountability Act (HIPAA) violations in the last five years. This statistic suggests that entities such as hospitals and clinics, need to ramp up their efforts for ensuring HIPAA compliance because it is one of the key steps toward achieving improved protection against cyber attacks.
Detecting Ransomware and Phishing Attacks
Currently, the most common cyber threats faced by healthcare entities include phishing attacks and ransomware. These are the most commonly used techniques by hackers trying to retrieve confidential patient information that is critical to protect. The best practices for preventing such threats involve data encryption tools, which are recommended for all covered entities.
Another solution that can be useful to healthcare organizations is a software that can create rules and can be integrated with different tools that can be adjusted in a way that allows them to automatically detect and report problems. Platforms with such capabilities should be a crucial part of each entity’s cyber defense efforts.
How to React in Case You Are Attacked
Even though there are tools designed to detect and prevent ransomware and phishing attacks, hackers often manage to find a way to go around all sorts of defenses and breach even the most sophisticated security armors. When that happens, organizations must be prepared to react as quickly and as effectively as possible with a proven solution.
To that end, all covered entities, including healthcare organizations, need to have a Computer Security Incident Response Team (CSIRT) in place. In order to help their CSIRT resolve cyber incidents, entities are advised to acquire platforms that have the ability to automatically notify CSIRTs when a cyber attack occurs, be it via e-mail or SMS, and gather a team of investigators to do the forensics on a given incident.
Incident Response platforms featuring specialized playbooks are also necessary for tackling healthcare-related incidents. They are the most indicated tool for resolving cyber incidents fast and efficiently, through their ability to accelerate the incident triage process, integrate with forensics and response systems, and predict similar events in the future. Some of those platforms (SIRPs) are also able to provide playbooks for vertical regulation, such as HIPAA and similar.
This past summer, many cyber security experts expressed their concerns that certain Russian groups were involved in the hacking attack on the U.S. Democratic National Committee’s (DNC) computer network, leaking 20,000 emails from various Democratic Party officials. The DNC hack made the headlines around the globe, and for good reason.
No matter who the perpetrator was, one thing is clear: the hack of the DNC servers inflicted serious harm to both the Democratic Party as an institution, as well as many of its members, mainly related to the public image of the party and of various individuals.
However, it could have had further, more wide-ranging implications, including an impact on the upcoming U.S. presidential election, which is why it is very important to understand what could have been done to prevent it, and what kind of response and management process for the incident should have been chosen.
Was the Hack Avoidable?
Even though it’s difficult to confidently say whether the DNC hack could have been avoided, without knowing the confidential specifics of the incident, there are a lot of things that could have been done that would have probably protected the DNC’s computer server much better.
The consensus among leading analysts familiar with this incidents is that the DNC hack was most likely conducted through spear phishing, which is one of the most common methods for initiating a cyber attack.
With that in mind, one of the easiest ways to avoid falling victim to such a fraud is to train people within your organization on how to recognize and react to such threats. People should be familiarized with the spear phishing technique and how it works, making them more aware of the difference between legitimate emails and links and malicious ones, with the latter being the basis of all phishing scams.
What’s the Appropriate Response to These Types of Incidents?
Sometimes, no matter how well every person within an organization is trained and educated on cyber security threats, attacks on a company or an institution server or network occurs, and that is when you need to be able to react as fast and as efficiently as possible to prevent the loss of confidential information, and avoid a major blow to your organization’s reputation, and consequently, your bottom line.
To that end, having a cyber incident response plan in place is key to bringing cyber incidents under control and minimizing or completely avoiding the potential consequences of a breach.
According to statistics from a recent AT&T report, 62% of organizations admitted to being breached in 2015, but only 34% of organizations polled had an incident response plan. These statistics inevitably point to the need for increasing awareness of the fact that every organization is highly vulnerable to cyberattacks, and the necessity of devising a plan and having the right tools that would help them mitigate the impact of any breach and go about their business as soon as possible.
