Beware of What Is Lurking in the Shadows of Your IT

Posted on by

This post was written with contributions from Joseph Lozowski. Comprehensive incident preparedness requires building out and testing response plans that consider the possibility that threats will bypass all security protections. An example of a threat vector that can bypass security protections is “shadow IT” and it is one that organizations must prepare for. Shadow IT […]

What Drives Incident Responders: Key Findings from the 2022 Incident Responder Study

Posted on by

Cyberattacks seldom happen when it’s convenient. In fact, it’s relatively common for them to occur on weekends or holidays — threat actors capitalize on the fact that there is fewer staff on site, and those who are there are focused on the coming weekend or time off. It’s also not uncommon for attacks of this […]

Solving the Data Problem Within Incident Response

Posted on by

One of the underappreciated aspects of incident response (IR) is that it often starts as a data problem. In many cases, IR teams are presented with an effect such as malware or adversary activity and charged with determining the cause through the identification of evidence that ties the cause and effect together within an environment […]
