The macOS system must ensure System Integrity Protection is enabled.

System Integrity Protection (SIP) must be enabled.

SIP is vital to protecting the integrity of the system as it prevents malicious users and software from making unauthorized and/or unintended modifications to protected files and folders; ensures the presence of an audit record generation capability for defined auditable events for all operating system components; protects audit tools from unauthorized access, modification, and deletion; restricts the root user account and limits the actions that the root user can perform on protected parts of the macOS; and prevents nonprivileged users from granting other users direct access to the contents of their home directories and folders.

Note: SIP is enabled by default in macOS.

Verify the macOS system is configured to enable System Integrity Protection with the following command:

/usr/bin/csrutil status | /usr/bin/grep -c 'System Integrity Protection status: enabled.'

If the result is not "1", this is a finding.

Configure the macOS system to enable "System Integrity Protection" by booting into "Recovery" mode, launch "Terminal" from the "Utilities" menu, and run the following command:

/usr/bin/csrutil enable
