Remove the Menial Tasks Through Automation

proven best practices to reduce and avoid alert fatigue

Alert fatigue is the desensitization when overwhelmed with too much information. The constant repetition and sheer volume of redundant information are painful and arduous but sadly often constitutes the daily reality for many people working in cyber security. Mike Fowler (DFLabs’ VP of Professional Services) discusses several best practices to help with some of the challenges involved in this in his recent whitepaper “DFLabs as a Force Multiplier in Incident Response”. I am going to discuss another one, but looking at it from a slightly different angle.

Imagine the scenario where we have tens of thousands of alerts. Visualize these as Jigsaw pieces with a multitude of different shapes, sizes and colors and the additional dimension of different states. We have alerts from a firewall, anomalies from behavioral analytics, authentication attempts, data source retrieval attempts or policy violations. Now, there are a lot of ways to shift through this information, for example by using a SIEM’s to correlate the data and reduce the some of the alerts. The SIEM could identify and cross-reference the colors and shapes of the jigsaw pieces so to speak.

The next question once that I’ve got the all the pieces I need for the puzzle is how do I put this together? How do I complete the puzzle and unlock the picture?

The “what does the jigsaw picture?” question is something that will often puzzle the responders, pun intended. How do you prioritise and escalate incidents to the correct stakeholders? How do you apply the correct playbook for a specific scenario? How do you know which pieces of information to analyse to fit the jigsaw pieces together and make sure the puzzle looks correct?

Automation process can speed up putting that puzzle together, but making sure you automate the right things is just as critical. If skilled staff are running search queries that are menial, repetitive and require little cognitive skill to execute, you should ask yourself why they are performing these and not instead focused on analyzing the puzzle pieces to figure out how they fit together?

Remove the menial tasks. Allow automation to do the heavy lifting so your teams are not only empowered by the right information they need to successfully manage the response to an incident but also to give them more time to figure out the why, how and what of the threat.

We also welcome you to join us for a webinar hosted by Mike Fowler on this topic on the 6th of September.
