Chapter 10: Hardening Communications


Communications can be the bane of any security administrator. They are required for business purposes in most cases, but can be the weak point in the security schema if not employed properly. To secure your network, you should

  • Use SSH in lieu of unencrypted protocols

  • Set up password-free logins as required

  • Replace r services and FTP with SSH equivalents

  • Implement SSH port forwarding

  • Secure X connections with SSH

  • User virtual private networks
