Insight #1

"Again we had an instance where a CVE was not appropriately fixed and a year later a new CVE was released for the same problem and a better fix. This brings back memories of log4j and numerous updates over a 2 week period. Because these sorts of things are common (and because new zero-days come out all the time) you need to have a solid plan in place to mitigate your risks of exploitation with technologies such as RASP. It’s one critical piece to your mitigation control layers"

Insight #2

"Running a scan against your developers' code and handing them a report with unverified findings (full of false positives and unreachable vulnerabilities) does nothing but create tension between the security team and engineering team. As our security processes and tooling evolve with the speed of engineering, it is imperative we find ways to get developers actionable results as part of their workflow. The waterfall approach to application security is dead."

Insight #3

"If your source code is leaked, your first worry should not be what’s in the source code. Your worry should be if the malicious actor is still roaming around your environment and what else they accessed. Immediately hire outside help for incident response and forensics analysis."
