Effective incident response
Posted on 06 February 2014.
Organizations are bombarded with potential threats every day. Most of these are small and irritating, not truly critical - but among those needles are little threads of larger actions at work. An incident response program enables you to pull out the needles that make up the haystack of the big picture, according to Jaime Blasco, Director at AlienVault Labs.

The ultimate goal of an incident response program is not only to effectively contain a single incident, but to start modeling the techniques of an attack. Incident response is based on an approach that detects and enumerates the steps taken by an attacker to compromise a system.

The incident response team then uses this information to drive future incident response activities. In this model, a behavior that may have seemed benign before analysis can act as a predictive indicator of a larger attack.

Building an incident response framework allows an organization to bring in vast quantities of enterprise and security data; build relationships among that data; and present it in a single, unified workflow. This workflow presents both the business and technical information in a single view. Analysts can spend much less time learning individual security control technologies and much more time analyzing, finding patterns, and making response decisions.

The key concepts to a successful incident response program are as follows:
  • Act on what you can manage—execute on what you know how to respond to effectively.
  • There is no boilerplate security policy that works for an organization all the time, outside of regulatory requirements. Remember—business processes define policy, not vice versa.
  • Security monitoring is an essential and foundational aspect of any incident response program.
As the name implies, incident response involves responding to some indicators of an actual or potential incident—indicators that are detected through security monitoring. Indicators are contextual information drawn from a number of technical and administrative sources.
