Rules within the template

The 267 rules provided in the zip package contain the following types of rules:

• Rules that check for compliance (audit) and provide remediation—205
• Rules that check for compliance (audit) but do not provide remediation—51
• Rules that do not check for compliance and do not provide remediation—11

The following are the details of the rules that are divided into parts:

• Rules not divided into parts = 188
• Rules divided into two parts (16 Rules) so (16* 2) = 32
• Rules divided into three parts (9 Rules) so (9* 3) = 27
• Rules divided into four parts (2 Rules) so (2* 4) = 8
• Rules divided into six parts (2 Rule) so (2* 6) = 12

The current rule count according to CIS SUSE Linux Enterprise 12 template after running the compliance job is 267 (188+ 32+27+8+12).
