What can you do to protect the systems on your networks?

  









Linux

  • Use Layered Security.

  • Create a Disaster Recovery Plan.

  • The external router should be hardened to block invalid, RFC 1918, RFC 2827, spoofed IP's & ICMP; outbound access list blocking, source routing & directed broadcast blocking, DoS attack prevention, limit administrative management, etc.

  • Harden firewall configuration to severely restrict inbound access, deploy DMZ’s, employ IPSec VPN’s w/ AES, use firewall level authentication, and restrict outbound ports.

  • Harden PC configurations, employ a host firewall, use WSUS for updates, use Firefox as browser, remove local administrative access from users, Group Policy to roll out security settings, encryption, bios passwords, etc.

  • Secure wireless (in order of preference): WPA2-EAP, WPA-EAP, WPA2-PSK, WPA-PSK, WEP, no encryption.

  • Employ Intrusion Prevention Systems (IPS).

  • Monitor internal networks for ARP/DHCP attacks.

  • Employ redundancy in routers, firewalls, switches, and servers.

  • Use physical security.

  • Make sure that off-site backups (Network/disk/tape) are created daily.
