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
