  • Inadequate Internet Security safeguards can allow unauthorised access to your network, with potentially disastrous consequences.

  • Consider implementing a Virtual Private Network (VPN), to provide robust security using a combination of technologies, such as firewall and end to end encryption. See also PKI.
  • Weak dial-in security standards can give unauthorised access to your network, the consequences of which could be very serious.

  • Resist requests for remote access facilities unless they are essential.
  • Consider first a VPN (see above); but where dial up access is a better choice, ensure that 'auto dial back' is employed whenever possible.
  • Remove any unnecessary privileges which may be available on users' accounts and which are not essential when accessing remotely. Alternatively, consider issuing separate, restricted accounts, with limited privilege which are available specifically for remote access.
