Rules within the template
The template contains the following types of rules:
- Rules that check for compliance and provides remediation - 177
- Rules that check for compliance but do not provide remediation - 53
- Rules that do not check for compliance and do not provide remediation – 17
The following are the details of the rules that are divided into parts:
- Rules not divided into parts - 207
- Rules divided into two parts - (25 rules divided into 2 parts) so (25 * 2) = 52
- Rules divided into three parts - (10 rules divided into 3 parts) so (10 * 3) = 30
- Rules divided into four parts – (1 rule divided into 4 parts) so (1 * 4) = 4
- Rules divided into five parts – (1 rule divided into 5 parts) so (1 * 5) = 5
- Rules divided into six parts - (2 rules divided into 6 parts) so (2 * 6) = 12
So, the current rule count as per CIS - Red Hat Enterprise Linux 7 template after running the compliance job is 310 (207 + 52 + 30 + 4 + 5 +12)
