# Verify ownership of System Login Banner for Remote Connections
 
## Description{% #description %}

To properly set the owner of `/etc/issue.net`, run the command:

```
$ sudo chown root /etc/issue.net 
```

## Rationale{% #rationale %}

Display of a standardized and approved use notification before granting access to the operating system ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance.

Proper ownership will ensure that only root user can modify the banner.

## Remediation{% #remediation %}

### Shell script{% #shell-script %}

The following script can be run on the host to remediate the issue.

```bash
#!/bin/bash

if id "0" >/dev/null 2>&1; then
  newown="0"
fi
if [[ -z ${newown} ]]; then
  echo "0 is not a defined user on the system"
  exit 1
fi
chown $newown /etc/issue.net
```

### Ansible playbook{% #ansible-playbook %}

The following playbook can be run with Ansible to remediate the issue.
