This detection rule identifies instances where the System Integrity Protection (SIP) feature on macOS is disabled using the command line utility `csrutil`. SIP is a critical security feature designed to protect the integrity of macOS by restricting the actions that the root user can perform on protected parts of the system. Disabling SIP is often used in post-exploitation scenarios where attackers aim to lower the defenses of the operating system to facilitate further malicious activity. The rule monitors process creation events and looks for command line invocations of `csrutil` with the 'disable' action, which indicates that an attempt has been made to weaken the system's security. This is particularly important for monitoring environments where security posture is critical, as disabling SIP can open the system to various types of attacks that may compromise sensitive data or system functions.
