## Audit Procedure

### Using Command Line

Perform the following to determine if TIPC is disabled.

```bash
grep "install tipc /bin/true" /etc/modprobe.d/CIS.conf
```

## Expected Result

```
install tipc /bin/true
```

## Remediation

### Using Command Line

```bash
echo "install tipc /bin/true" >> /etc/modprobe.d/CIS.conf
```

## Default Value

TIPC kernel module is available by default.
