Tips for Network Security

  • Create a Stronger Domain Password Policy
  • Implement threat detection controls for alerts for new activity
  • Make sure Domain controllers have a GPO in place to prevent storing of LM hashes.
  • Update all devices including routers/switches
  • Get rid of  default passwords, even on printers (printers are a way in!)
  • Limit ports inbound from the Internet or outbound to the Internet
  • Order a Penetration Test at least once a year
