How to Create a Control Manifest

Language:

This procedure explains how to create a baseline, or control, manifest for comparison. Use this type of manifest when you are installing many systems from a central image. Or, use this type of manifest to run comparisons when you want to verify that the installations are identical. For more information about control manifests, see BART Manifest. To understand the format conventions, see Example 24, Explanation of the BART Manifest Format.

Note - Do not attempt to catalog networked file systems. Using BART to monitor networked file systems consumes large resources to generate manifests of little value.

Before You Begin

You must assume the root role. For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.3.

After customizing your Oracle Solaris system to your site's security requirements, create a control manifest and redirect the output to a file.
```
# bart create options > control-manifest
```
–R
Specifies the root directory for the manifest. All paths specified by the rules are interpreted relative to this directory. All paths reported in the manifest are relative to this directory.

–I
Accepts a list of individual files to be cataloged, either on the command line or read from standard input.

–r
Is the name of the rules file for this manifest. A - (minus sign) argument reads the rules file from standard input.

–n
Turns off content signatures for all regular files in the file list. This option can be used to improve performance. Or, you can use this option if the contents of the file list are expected to change, as in the case of system log files.
Examine the contents of the manifest.
For an explanation of the format, see Example 24, Explanation of the BART Manifest Format.

(Optional)Protect the manifest.
One way to protect system manifests is to place them in a directory that only the root account can access.
```
# mkdir /var/adm/log/bartlogs
# chmod 700 /var/adm/log/bartlogs
# mv control-manifest /var/adm/log/bartlogs
```
Choose a meaningful name for the manifest. For example, use the system name and date that the manifest was created, as in mach1-120313.

Example 24 Explanation of the BART Manifest Format

In this example, an explanation of the manifest format follows the sample output.

# bart create

Each manifest consists of a header and file entries. Each file entry is a single line, depending on the file type. For example, for each file entry in the preceding output, type F specifies a file and type D specifies a directory. Also listed is information about size, content, user ID, group ID, and permissions. File entries in the output are sorted by the encoded versions of the file names to correctly handle special characters. All entries are sorted in ascending order by file name. All nonstandard file names, such as those that contain embedded newline or tab characters, quote the nonstandard characters before sorting.

Lines that begin with ! supply metadata about the manifest. The manifest version line indicates the manifest specification version. The hash line indicates the hash mechanism that was used. For more information about the SHA256 hash that is used as a checksum, see the sha2(3EXT) man page.

The date line shows the date on which the manifest was created, in date form. See the date(1) man page. Some lines are ignored by the manifest comparison tool. Ignored lines include metadata, blank lines, lines that consist only of white space, and comments that begin with #.
