Perimeter Security Checklist

Identify all physical and logical connections to the outside world.

Take the lead in implementing new Internet-based technologies securely from the start.

Protect all routes through which files can enter your network with anti-malware software.

Always patch all OSs, perimeter-related devices, applications, and servers as soon as patches are available.

Insulate remotely accessible applications with application-level gateways such as ISA Server and plug-ins from ISA Server partners.

Consider advanced perimeter security solutions for IM, XML, and Web filtering.

If you need an IDS or IPS, plan for the necessary support and maintenance.
