Security programs often equate tool deployment with security coverage. An organization may deploy endpoint protection, a firewall, vulnerability scanners, identity monitoring, and a SIEM and assume the environment is fully monitored. From a procurement perspective the organization appears well equipped. From a detection perspective there are often significant blind spots. Coverage is not created by…

Today’s Topics: Cookie-Gated PHP Web Shells and Cron-Based Persistence Are Redefining Stealth on Linux Servers Recent findings from Microsoft Defender Security Research Team point to a quiet but effective evolution in web shell tradecraft, where HTTP cookies are now being used as the primary control channel for PHP-based backdoors operating on Linux servers. This method…

DNS traffic is one of the most consistent and observable forms of network activity in an enterprise environment. Nearly every system relies on DNS resolution to communicate with internal services and external infrastructure. Applications, update mechanisms, authentication workflows, and cloud services all generate DNS queries as part of normal operation. This makes DNS logging one…

Security programs often measure visibility in terms of ingestion volume. SIEM dashboards display daily event counts, ingestion rates, and storage utilization, which can create the impression that higher log volume corresponds directly to stronger detection capability. Many environments collect endpoint telemetry, authentication logs, firewall events, DNS activity, cloud audit logs, and application logs with the…

Today’s Topics: CVE-2025-53521 Reclassified as RCE as Active F5 BIG-IP APM Exploitation Lands in CISA KEV CVE-2025-53521 has moved from a relatively underprioritized denial-of-service issue into something far more operationally significant, now reclassified as a remote code execution vulnerability with a CVSS v4 score of 9.3 and formally added to CISA’s Known Exploited Vulnerabilities catalog…

Zero Trust becomes operational the moment a Security Operations Center is tasked with validating it. In federal environments, this shift is especially visible. Executive mandates such as OMB M-22-09 and the DoD Zero Trust Strategy require identity-centric access, device health validation, continuous monitoring, and measurable progress. Those mandates remain theoretical until the SOC can produce…

Today’s Topics: Compromised IP Cameras Have Become an Intelligence Collection Layer Internet-connected cameras have historically been treated as low-priority security concerns. They were associated with botnet activity, unauthorized viewing, or basic demonstrations of weak authentication controls. That characterization no longer reflects how these devices are being used. Recent conflict activity shows a clear transition from…

In a federal Security Operations Center (SOC), detection quality is not defined by alert volume or dashboard metrics. It is defined by how effectively the SOC reduces adversary dwell time, how accurately it distinguishes signal from noise, and how consistently it protects mission systems under regulatory scrutiny. Federal environments introduce architectural and governance complexity: hybrid…

DFARS 252.204-7012 is one of the fastest ways to find out whether a security program is real. The clause does not just ask for “security controls.” It lays out a set of time-bound actions that kick in the moment a contractor discovers a cyber incident affecting a covered contractor information system, the covered defense information…

Trusted Internet Connections 3.0 represents a structural shift in how federal agencies secure external connections. Earlier versions of TIC consolidated traffic through limited access points and required standardized security stacks at those gateways. That model reflected an environment where most users and systems operated inside agency-controlled networks. TIC 3.0 acknowledges that federal IT environments now…
