When Detection Stops Threats but Leaves the Root Cause Unfixed

The useful part

See how both work together across incident response in this DZone + Datadog webinar on Oct. Explore the Webinar DZone Software Design and Architecture Security Detection and Response Did Its Job. Here's how attack evidence, ownership mapping, root cause tracing, developer routing, and retesting turn a contained incident into an actual fix.

How it works

• Detection and response worked exactly as intended, automatically, correctly, and fast.
• The incident still has to be reconstructed, connected to the team responsible for the affected service, and followed back to whatever condition made the attack possible.
• The surrounding runtime evidence can show an investigator what was happening on the system when the alert fired, rather than leaving the team to piece together the incident after the fact.
• That evidence can include processes being executed, network connections, changes to files, and the lineage between processes.
• On Linux hosts, Kubernetes nodes, and VMs, Sysdig can collect system-call data using eBPF-based drivers, with kernel modules also supported.

What to take from it

Veracode's State of Software Security Report gives some sense of the problem's scale. Critical security debt was up 20% year over year, and high-risk vulnerabilities, those considered both severe and highly exploitable, climbed 36%. Detection has made progress, but finding a problem quickly and implementing fixes are clearly not the same thing.

Example or evidence

• Fixing what made that possible is a separate job, which is exactly why runtime and build-time security have to work together rather than standing in for each other.

• The attacker may be gone, but the opening they used can still be sitting there waiting for the next attempt.
• A cybersecurity platform that's actually good at threat detection and incident response has to do more than contain the immediate event.
