Updating CIS for Oracle Linux 7 to newer benchmarks

This document provides information about the hotfix containing Center for Internet Security (CIS) templates for Oracle Linux 7 Benchmark Version 3.0.0. This template contains implementation for 245 rules that can be installed on TrueSight Server Automation 8.9.00 or later.

Before you begin

Before you install this hotfix, make sure that the following requirements are met:

  • All the compliance content provided by BMC is at least updated to version 8.9.
  • For all application servers in your environment, back up the following directory:
    <Application_Server_installation_directory >/share/sensors
    This directory contains extended object scripts.

Step 1: Download the template file

Do the following:

  1. Log in to the ftp.bmc.com host using the SFTP protocol. 

  2. Download the CIS - Oracle Linux 7.zip and extended_objects.zip packages from the following location:

    Verify the extended objects present on the application. If the md5sums match, go ahead and replace them. If these md5sums do not match, you must manually merge the fixes.

Step 2: Import the compliance template

Do the following:

  1. Log in to the TrueSight Server Automation console.
  2. Right-click Component Templates and select Import
  3. Select Import (Version-neutral).

  4. From the temporary directory, select the CIS - Oracle Linux 7.zip package, and click Next. The CIS - Oracle Linux 7.zip package contains the CIS template for Oracle Linux 7. 

  5. To import the template, select CIS - Oracle Linux 7 and click Next.

    Note

    Ensure that you select the Update objects according to the imported package and Preserve template group path options before you click Next.


  6. Navigate to the last screen of the wizard and then click Finish.

    The template is imported successfully.

Rules within the template

The template contains the following types of rules:

  • Rules that check for compliance and provides remediation - 176
  • Rules that check for compliance but do not provide remediation - 52
  • 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 - 205

  • 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 - Oracle Linux 7 template after running the compliance job is 308 (205 + 52 + 30 + 4 + 5 +12)

The following table lists the compliance checks with comments:
