To increase the time an attacker needs to exploit this flaw you could override the `StartLimitInterval=` (called StartLimitIntervalSec in newer systemd versions) and `StartLimitBurst=` settings. In this way the attack may require much longer to be successful. To edit the journald service use `sudo systemctl edit systemd-journald.service` and add: ``` [Service] StartLimitInterval=120 StartLimitBurst=3 ```
