# 5.2.1 Ensure permissions on /etc/ssh/sshd_config are configured (Scored)

## Profile Applicability

- Level 1 - Server
- Level 1 - Workstation

## Description

The `/etc/ssh/sshd_config` file contains configuration specifications for `sshd`. The command below sets the owner and group of the file to root.

## Rationale

The `/etc/ssh/sshd_config` file needs to be protected from unauthorized changes by non-privileged users.

## Audit Procedure

Run the following command and verify `Uid` and `Gid` are both `0/root` and `Access` does not grant permissions to `group` or `other`:

```bash
stat /etc/ssh/sshd_config
```

## Expected Result

```
Access: (0600/-rw-------)  Uid: (    0/    root)   Gid: (    0/    root)
```

## Remediation

Run the following commands to set ownership and permissions on `/etc/ssh/sshd_config`:

```bash
chown root:root /etc/ssh/sshd_config
chmod og-rwx /etc/ssh/sshd_config
```

## Default Value

Not configured by default.
