Vulnerability Management

A comprehensive guide to external attack surface management (EASM) covering continuous asset discovery, shadow IT identification, cloud misconfiguration detection, certificate and DNS monitoring, third-party risk from digital supply chains, exposure prioritization frameworks, and tooling comparison across commercial platforms (Censys, Shodan, CyCognito, Mandiant ASM, Microsoft Defender EASM) and open-source alternatives. Includes practical implementation workflows for reducing organizational attack surface from thousands of unknown exposures to a managed, monitored inventory.

An in-depth guide to understanding, detecting, and mitigating zero-day vulnerabilities. Covers the zero-day lifecycle from discovery through exploitation and patch release, detection techniques including behavioral analysis, memory forensics, exploit detection heuristics, and threat intelligence integration, mitigation strategies such as virtual patching, microsegmentation, application allowlisting, and exploit mitigation technologies (ASLR, DEP, CFI), plus organizational response frameworks and the economics of the zero-day marketplace.

A detailed hands-on comparison of the three dominant vulnerability scanning platforms: Tenable Nessus, Qualys VMDR, and Rapid7 InsightVM. Covers scanning engine architecture, detection accuracy, false positive rates, asset discovery, cloud coverage, reporting depth, API capabilities, pricing models, and real deployment considerations that determine which platform fits different organizational profiles.
