| If using AIDE, verify the configuration contains the sha256 or sha512 options for all monitored files and directories. Here is an example AIDE configuration fragment. SampleRule = p+i+l+n+u+g+s+m+c+acl+xattrs+sha256 /bin SampleRule If either the sha256 or sha512 option is not present, this is a finding. If using a different file integrity tool, check the configuration per tool documentation. |
