Leveraging SOAR Technology to Facilitate Knowledge Transfer in Security Operations

Earlier this year I was talking to a colleague about the state of SOC operations and how I was looking forward to going to the SANS Security Operations Summit in New Orleans in July. The folks who attend SANS events are at the top of their game and let’s be honest, SANS provides some of the best training in our industry, so what’s not to love?

The conversation quickly turned to how to provide better scalability within SOC operations. Given that our teams are confronted with an increased number of alerts coming from more sophisticated actors on a daily basis, how do we keep up? We spoke about the need for better security automation to enrich the information available at the onset of an incident and how malware has been automating since the Morris worm 30 years ago.

At one point she asked me how best we can handle the transfer of incident handling “tribal knowledge” from the senior Incident Response personnel to the junior members, given the daily workload they carry. I thought about it for a moment and threw out that perhaps increased spending for machine learning or AI could help bridge the knowledge gap. She then asked, “Couldn’t we take that money and invest in knowledge transfer within the team instead?”. That simple and simultaneously complex question got me to thinking about how we can better utilize existing resources to provide that knowledge transfer in an environment as dynamic and rapidly changing as an Incident Response organization.

I thought this topic was interesting enough to make it my focus for my upcoming speaking engagement at SANS.

As we already know an increased workload coupled with an industry-wide shortage of skilled responders is heavily impacting operational performance in Security Operations Centers (SOC) globally and an integral part of the solution is formulating a methodology to ensure that crucial knowledge is retained and transferred between incident responders. By utilizing Security Orchestration, Automation and Response (SOAR) technology, security teams can combine traditional methods of knowledge transfer with more modern techniques and technologies.

Join me at the SANS Security Operations Summit on July 30, 2018 at Noon for an informal “Lunch and Learn” session to discuss how we ensure that the Incident Response knowledge possessed by our senior responders can be consistently and accurately passed along to the more junior team members while simultaneously contributing to the Incident Response process. I look forward to meeting you there.

If you are not attending the summit, don’t worry, you can visit our website to find out more information about the benefits of utilizing a SOAR solution with DFLabs’ IncMan SOAR platform.  Alternatively, if you would like to have a more in-depth discussion, you can arrange a demo to see IncMan live in action.

Automated Responder Knowledge (ARK) in Action

We released our Machine Learning Engine PRISM in our most recent 4.2 release. The first capability that we developed from PRISM is our Automated Responder Knowledge (ARK). This capability will change the way incident responders and SOC analysts respond to incidents, and how they share and transfer their entire knowledge to the rest of the team. The key to this capability is that it learns from your own analyst’s responses to historical incidents to guide the response to new ones.

We are not re-inventing the wheel with this feature. SOC and Incident Response teams have been doing this the old-fashioned way for a long time – through 6-12 months training. What we’re doing is providing a GPS and Satellite Navigation, guiding the wheel and giving you different paths to choose from according to the terrain you are in.

We do this by analyzing incidents and their associated attributes and observables, to work out how closely they are related. Then we can suggest actions and playbooks based on your organizations’ historical responses to similar threats and incidents.

Using Automated Responder Knowledge (ARK) in IncMan

Step 1: Not really a step – as it’s done automatically by Automated Responder Knowledge (ARK), but this occurs in the background for every incoming incident. Every Incident possesses a feature space1 that contains all the information related to it, composed of every attribute, associated observable and attached evidence. ARK analyses the feature spaces associated with every incident ever resolved. When a new incident is opened, it is scored and ranked and then compared by ARK to the historical model to identify related incidents or actions based on similar and shared attributes. The weighting of the ranking can be customized by analysts.

Step 2: Open the incident, selecting the applicable incident type. To save time, you can create an incident template to prepopulate some of the contexts automatically in future.

Step 3: Select Playbooks, and PRISM.

In the next screen, you will see a variety of suggested related actions and related incidents based on the feature space that your incident type is matched with. The slider at the top is used to determine the weighting in ranking for actions that are suggested. For example, if I move the slider to the left, the entire feature space actions appear, then if I move the slider to the far-right only a few actions appear from highly ranked incidents.

Step 4: Determine which automation and actions you want to use from the suggestions. After saving, you will be presented with options such as Auto-Commit, Auto-Run, Skip Enrichment, Containment, Notification or Custom Actions. You have the ability to select only the actions you want to automate. If you are concerned about running containment automatically, for example, you just deselect those options.

Step 5: The automated actions are executed, resolving the incident, based on prior machine-learning generated automated responder knowledge.

ARK is designed to facilitate knowledge transfer from senior to junior analysts and to speed up incident response by applying machine learning to automate the knowledge gathering and analysis.
