-Create a two- to three-page Network Security Checklist that will include the components to be used for multilevel security communications in a multilevel trusted environment.

In your checklist, address the severity of threats from a security and risk management aspect. . Those relationships have varying trust levels that translate into multilevel security in communications and information sharing, and are implemented technologically through policies for firewalls, public-key infrastructure (significance of public-key infrastructure), systems certification and accreditation, security vulnerability testing, SSL, IPSEC, and VPNs. Your network security checklist will encompass the levels of degrees of restrictions in these security components to defend against threats while allowing for communications and information sharing.

While developing your checklist, you should include (but you are not limited to) the following components:

• communications and data-sharing policies and the network devices that will be used to implement these policies

• firewalls and how the rule sets will be determined
• systems certification and accreditation demonstrations as required by network administrators who are hosting the summit
• secure communications protocols

• digital authentication mechanisms—How will your nation team establish PKI systems and develop public/private key mechanisms as well as digital certificates? Will your nation team have a centralized key storage system? How else will you establish trust between the nations? You do not have to build an encrypted communications system for your nation team, but you should provide your plan for trusted communications in your Network Security Checklist.
• SSL and IPSEC protocols

• VPNs
