Other options include:
- Removing their LAN or other hosts usernames and passwords so that even if they are able to access the environment, they cannot use or abuse any resources or assets.
- Changing all your Administrator or root type passwords in case any of your former employees has access to these.
- Auditing your environment for old users, unknown users, or generic users that might be used to perform malicious acts. If those former employees can dial up or connect remotely to your organization without a username and password then I feel you have a broader security problem than simply potential malicious behaviour by laid-off workers and you need to secure your perimeter as soon as possible with appropriate access controls.
