| Secure shares to reduce worm susceptibility |
| Network shares are one of the mechanisms that worms and viruses use to spread. They often look |
| for shares with no restrictive security and plant contaminated files in the shares to also infect the |
| computers of users who access those files. |
| You can reduce your network's susceptibility to worms and viruses by tightening security on |
| network shares. Take these steps to protect your network from worms and viruses: |
| Ensure that all shares are stored on NTFS volumes, and convert FAT volumes as necessary. |
| Remove the Everyone group from the sharing and NTFS permissions, and add only those security |
| groups or user accounts that should have access to the share. |
| Where possible, hide shares from browsing by adding a dollar sign [$] to the end of the share name. |
| In addition to these steps, firewalls, virus scrubbers, and adding security patches to your operating |
| systems and applications are other important ways to further reduce your organization's |
| susceptibility to worms and viruses. |
