A Weekend in Incident Response #27: Small Businesses Need to Improve Their Ability to Respond and Eradicate Cyber Incidents

Small businesses may not be the first thing that comes to people’s minds when talking about prime targets for cyber attackers. This is because government agencies, corporations, along with organizations and companies that are part of a country’s critical infrastructure are much more coveted targets, due to the high reward potential associated with them – both in terms of financial gains and retrieving confidential information. However, data breaches and other types of cyber incidents have recently become a common occurrence for many small businesses. Hackers are increasingly trying to gain access to the emails and acquire personal and other confidential information of their employees that are in charge of handling the companies’ finances.

One of the reasons why small businesses are seeing a rise in cyber attacks and data breaches is that cyber criminals have become increasingly aware of the fact that hacking into a small business’ computer network is fairly easy, in part due to the low cyber-security awareness of their employees. Additionally, the cyber defense programs and solutions that small businesses utilize are weak or even non-existent, thus making them easy prey despite not having a particularly high financial reward potential for cyber criminals. Lastly, small businesses have adapted to cloud services to conduct a large portion of their operations, and most cloud providers offer data encryption, making them extremely vulnerable to cyber threats.

What Criminals Are After

In most cases, the typical cyber attack on a small business’ computer network aims to retrieve a company’s financial information, employee records, customer records, as well as customer credit or debit card information, which they could later use to steal company funds, commit financial fraud, identity theft, or extortion.

The most common types of cyber security events faced by small businesses include phishing, SQL injections, malware, ransomware, DDoS attacks, and web-based attacks. The first line of defense against these attacks are a company’s employees. They need to go through cyber-security training to be able to recognize and detect a cyber threat – with statistics showing that a large part of data breaches are related to employee inattention.

Security Automation Is the Next Line of Defense

While cyber-security training for employees is something that every company needs to provide in this age of constant threat of cyber attacks, that alone is not enough to protect businesses against all potential cyber security incidents. Raising employee cyber-security awareness should be followed up by implementing appropriate solutions aimed at detecting, tracking, and eradicating cyber security incidents. In that regard, small businesses could use a security automation and orchestration platform, which can greatly reduce their reaction time following a cyber incident, and prepare them for more timely detection and prevention of future attacks.

Such a platform can help you protect customer and employee information, as well as valuable financial information, since it is capable of assessing the scope of the incident, identifying the affected device or devices, and containing the damage, by providing complete reports on the damages occurred, in addition to providing specialized rules and strategies that allow cyber-security professionals to react much more quickly and effectively to eradicate the incident. These types of platforms are the most straightforward and effective solution for small businesses’ concerns regarding cyber threats, which they are only going to see more of in the near future.

A Weekend in Incident Response #25: Closing the Gap in U.S. Federal Agencies Cyber Security

In March, the U.S. Office of Management and Budget (OMB) released a report on the cyber performance of federal agencies, revealing that a total of 30,899 cyber incidents were reported by them in fiscal 2016. The OMB states that this is an alarming figure and that it indicates that there are significant gaps in the cyber defenses of federal agencies across the country.

According to the report, federal agencies have made good progress in improving their cyber defenses last year, but are still quite vulnerable to cyber attacks and need to ramp up their efforts for protecting their networks and data. Of the almost 31,000 incidents in 2016, a total of 16 have been designated as major incidents, which means they had the potential to threaten national security, the economy, civil liberties, or relations with foreign countries. With this in mind, federal agencies need to keep stepping up their efforts for strengthening their defense against cyber attacks.

Detecting and Preventing Malware and Phishing Attacks

Given that the report states the vast majority of cyber incidents reported by federal agencies involved phishing attacks and malware infections, they are now advised to look into improving their capabilities to respond to these types of attacks and detect and prevent them in the future. There are a couple of ways this can be done. When talking about cyber incident response, one of the most cost-effective and efficient solutions is employing an automation-and-orchestration cyber incident response platform, capable of keeping cyber security events under control, mitigating risks and improving an organization’s ability to prevent future attacks.

These platforms have wide-ranging features that give Computer Security Incident Response Teams (CSIRTs) the opportunity to detect, track and predict cyber security breaches immediately. There are platforms that can help reduce reaction times when responding to an incident, through the employment of automated playbooks designed to accelerate the response to specific types of attacks – such as malware or phishing attacks, which are often faced by government agencies.

Integrated Knowledge Base to Guide You Through the Response Process

Through the use of those playbooks, as well as the available integrated knowledge base, cyber security professionals can quickly identify where an attack is coming from and determine the location of the infected or breached device or part of the network, and follow that up with the containment of the damage to prevent it from spreading.

What’s more, these types of platforms can create automatically generated reports on every incident, in addition to collecting digital evidence for forensic investigations, allowing for the quick notification of law enforcement and provide them with the necessary documentation, thus complying with data breach notification and reporting regulations.

This approach can increase cyber security teams’ ability to resolve incidents in a timely manner and prevent government agencies from losing valuable and sensitive data that could be used by attackers for ransomware or to damage the country’s critical infrastructure.

A Weekend in Incident Response #21: How to Mitigate Cyber Security Risks in Health Care?

Health care institutions are facing an increasing risk of cyber attacks. There are a few reasons why organizations providing health-care services are under such a high cyber security risks, with the increase utilization of IoT devices singled out by security experts as the leading one over the last couple of years. The fact that many hospitals around the world keep adopting BYOD policies only raises the risk of cyber attacks in the health care sector.

Considering that there is more than enough statistics showing that the most common cyber attacks on health-care organizations include phishing incidents and malware attacks, it is safe to say that IoT devices and BYOD policies are exposing this sector to an ever higher and constant cyber security threat, requiring increased efforts for raising cyber security awareness among employees and implementing advanced incident response measures.

Developing an Effective Incident Response Plan

Incident response plans are one of the essential elements of any organization’s efforts for mitigating cyber security risks. Having a comprehensive and constantly updated incident response plan helps organizations be prepared for any type of cyber attack in case their cyber defense is breached, and odds for that to occur are extremely high at any given moment. While establishing an effective incident response plans, health-care organizations are advised to start by acquiring a cyber incident response platform that provides an automated and orchestrated response to all sorts of cyber attacks.

Health-care institutions could use such a platform to contain the damage and prevent the loss of confidential and sensitive patient data in the aftermath of a breach. A cyber incident response platform can provide them with automated playbooks that allow cyber incident response teams to react to different types of attacks quickly and effectively.

Phishing and Malware Incident Playbooks

There are platforms providing playbooks for phishing attacks and ransomware attacks, which health-care institutions are often facing. Those playbooks will tell cyber security teams exactly what to do when their information systems and computer networks are attacked through one of the above-mentioned methods. Playbooks help CSIRTs prepare their systems for potential phishing attacks, identify them as soon as they occur, contain the damage, and recover from any incident in a timely manner. When it comes to ransomware attacks, playbooks help you reduce the time it takes you to establish a precise diagnosis, identify the kind of malware and the infection target, and assess the range of infection. Also, they help you determine the level of impact of an attack, suggesting taking specific actions that are appropriate for any given level of impact.

With that in mind, automation and orchestration platforms with automated playbooks are one of the best solution for any health-care organization that is under a threat of getting attacked by cyber criminals.

A Weekend in Incident Response #5: Reducing the Risks of Cyber Attacks in the Healthcare Sector

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.
