A rogue access point is a wireless access point that has been installed on a network without the authorization or knowledge of the network administrator. A rogue access point can pose a serious security risk, as it can allow unauthorized users to access the network, intercept network traffic, or launch attacks against the network or its devices. The first action that should be taken to protect the network while preserving evidence is to disconnect the rogue access point from the network.
This will prevent any further damage or compromise of the network by blocking the access point from communicating with other devices or users. Disconnecting the rogue access point will also preserve its state and configuration, which can be useful for forensic analysis and investigation.
Disconnecting the rogue access point can be done physically by unplugging it from the network port or wirelessly by disabling its radio frequency.

OpenVAS is an open-source tool that performs comprehensive vulnerability scanning and assessment on the network. It can generate reports and evidence of the scan results, which can be used for auditing purposes.

Mitigation involves implementing technical or administrative controls to reduce the impact of an attack. For zero-day exploits, this could include installing network-based protections, enhancing monitoring, or applying threat intelligence to detect or contain potential exploit attempts.

Virtual machine (VM) escape attacks target vulnerabilities in the hypervisor supporting a virtualized environment. The strongest control to protect hypervisors against these attacks is to keep them patched.
