      Bullet-proof network operating systems dont exist, but there are some common-sense steps that IT managers can take to make the NOS a less-attractive target for mischief-makers (and worse).

      • Identify and remove unused applications and services. The fewer components intruders can get their hands on, the better off your networks will be.
      • Implement and enforce strong password policies. Remove or disable all unnecessary accounts. This includes immediately removing accounts when workers leave the company.
      • Limit the number of administrator accounts available, and make sure users and IT staff have only the privileges they need to do their jobs.
      • Set account lockout policies to discourage password cracking.
      • Remove unused file shares.
      • Keep an eye out for new security patches and hot fixes.
      • Log all user account and administrative task transactions. This is an extremely important step for forensics if your network OS does get hacked.
      • Beware of “social engineering” tactics. Make sure that no one gives out important security information such as administrator passwords without getting approval from managers.
      • Keep a secure backup solution handy to restore all systems in case of emergency.
