# Tanzu Application Service | ||
|
||
## Overview | ||
|
||
This project contains content for compliance remediation of the Tanzu Application Service(TAS) for Canonical Ubuntu STIGs. | ||
|
||
## Using this Repo | ||
|
||
This repos is split into | ||
- jammy-stig-compliance-release - BOSH release to fix STIG controls for Jammy Stemcell(ubuntu 16.04). | ||
- xenial-compliance-release - BOSH release to fix STIG controls for Xenial Stemcell(ubuntu 22.04). | ||
- \<VERSION\>/docs - TAS version specific upporting documentation will be made available here as needed. | ||
|
||
## Disclaimer | ||
|
||
VMware no liability for the consequences of applying specific configuration settings made on the basis of the SRGs/STIGs and Hardening Guides. It must be noted that the configuration settings specified should be evaluated in a local, representative test environment before implementation in a production environment, especially within large user populations. The extensive variety of environments makes it impossible to test these configuration settings for all potential software configurations. | ||
|
||
For some production environments, failure to test before implementation may lead to a loss of required functionality. Evaluating the risks and benefits to a system’s particular circumstances and requirements is the system owner's responsibility. The evaluated risks resulting from not applying specified configuration settings must be approved by the responsible Authorizing Official. | ||
|
||
Furthermore, VMware implies no warranty that the application of all specified configurations will make a system 100 percent secure. Security guidance is provided for the Department of Defense. While other agencies and organizations are free to use it, care must be given to ensure that all applicable security guidance is applied both at the device hardening level as well as the architectural level. Some of the controls may not be configurable in environments outside the DoDIN. | ||

# jammy-stig-compliance-release | ||
<a name="warning">:warning: The `jammy-compliance-release` is not compatible with `auditd` job in [os-conf-release](https://github.com/cloudfoundry/os-conf-release)</a> | ||
|
||
## STIG | ||
The `stig` is intended to be used to change the stemcell configurations to pass Bionic STIG rules, since a Jammy STIG has not been published yet | ||
|
||
### fixes | ||
| VID | Title| | ||
|---|---| | ||
| V-238309| The Ubuntu operating system must generate audit records for privileged activities, nonlocal maintenance, diagnostic sessions and other system-level access. | | ||
| V-238216| The Ubuntu operating system must configure the SSH daemon to use Message Authentication Codes (MACs) employing FIPS 140-2 approved cryptographic hashes to prevent the unauthorized disclosure of information and/or detect changes to information during transmission. | | ||
| V-238217| The Ubuntu operating system must configure the SSH daemon to use FIPS 140-2 approved ciphers to prevent the unauthorized disclosure of information and/or detect changes to information during transmission. | | ||
| V-255912| The Ubuntu operating system SSH server must be configured to use only FIPS-validated key exchange algorithms. | | ||
|
||
### false positives | ||
- V-238258 | ||
The audit rules exits. To verify run: | ||
1. `# grep setxattr /etc/audit/audit.rules | grep fsetxattr | grep lsetxattr | grep removexattr | grep fremovexattr | grep lremovexattr` | ||
|
||
and verify the output contains | ||
|
||
``` | ||
-a always,exit -F arch=b64 -S setxattr -S lsetxattr -S fsetxattr -S removexattr -S lremovexattr -S fremovexattr -F auid>=500 -F auid!=4294967295 -k perm_mod | ||
-a always,exit -F arch=b32 -S setxattr -S lsetxattr -S fsetxattr -S removexattr -S lremovexattr -S fremovexattr -F auid>=500 -F auid!=4294967295 -k perm_mod | ||
``` | ||
2. `# auditctl -l | grep setxattr | grep fsetxattr |grep lsetxattr | grep removexattr | grep fremovexattr | grep lremovexattr` | ||
|
||
and verify the output contains | ||
|
||
``` | ||
-a always,exit -F arch=b64 -S setxattr -S lsetxattr -S fsetxattr -S removexattr -S lremovexattr -S fremovexattr -F auid>=500 -F auid!=4294967295 -k perm_mod | ||
-a always,exit -F arch=b32 -S setxattr -S lsetxattr -S fsetxattr -S removexattr -S lremovexattr -S fremovexattr -F auid>=500 -F auid!=4294967295 -k perm_mod | ||
``` | ||
### usage | ||
- `bosh cr && bosh ur` | ||
- Edit the release versionin the [runtime-config-stig](runtime-config-stig.yml) | ||
- `bosh urc --name stig-compliance runtime-config-stig.yml` | ||
- `Apply Changes` | ||
