About this tag
Incident response on WindowsForum.com covers real-world security events and the practical steps administrators must take when a breach or compromise is suspected. Discussions include patching critical vulnerabilities under active exploitation, such as CVE-2026-35273 in PeopleSoft and CVE-2026-20182 in Cisco SD-WAN, as well as analyzing threat clusters like OP-512 targeting IIS web shells. The tag also addresses Microsoft 365 threat detection and response for MSPs, Azure-native observability tools for incident investigation, and the operational challenges of responding to cloud outages like Exchange Online EX1331830. Common themes include the need for immediate isolation, log auditing, and treating exposed systems as compromised until proven otherwise.
