AI-generated code has moved from developer experiment to production reality, and security teams are now dealing with the result: faster software output, more code entering review, and a new class of AppSec risk where code can look clean, functional, and production-ready, yet still contain common security flaws. GitHub reported that nearly 80% of new developers…

Today’s Topics: Microsoft Defender False Positive Shows How Certificate Trust Incidents Can Create Operational Confusion Microsoft Defender’s recent false positive involving DigiCert root certificates is a good example of how security tooling can create real operational concern even when the original alert is not tied to an active infection on the affected device. The issue…

If you are preparing for CMMC 2.0 certification, the question is not whether you need a SIEM. The question is whether your logging, alerting, and monitoring architecture can survive a Level 2 assessment tied directly to NIST SP 800-171.

Kerberoasting is a credential theft technique that targets service accounts in Microsoft Active Directory environments. The attack allows a domain user to request Kerberos service tickets for accounts associated with Service Principal Names (SPNs) and extract encrypted credential material that can be cracked offline. If the attacker successfully recovers the password for a service account,…

Multi-factor authentication has become one of the most widely deployed identity protections in enterprise environments. Many organizations view MFA deployment as the primary milestone for identity security, and compliance frameworks frequently emphasize its importance. Enabling MFA significantly reduces the risk of simple credential theft attacks, yet it does not provide complete protection against account compromise.…

Audit readiness is often treated as a periodic project. Organizations preparing for compliance assessments collect policy documents, export reports, review configurations, and assemble evidence shortly before the auditor arrives. This approach can produce acceptable results for a single assessment cycle, yet it often requires significant effort and leaves little assurance that controls remained effective between…
