1) Kerberos is an authentication model designed around the concept of using tickets for accessing objects

2) Role-based access control (RBAC) is designed around the type of tasks people perform.

3) A formal manner of describing the necessary and sufficient portions of the IPsec protocol series to achieve a specific level of protection is a(n) Security Association (SA).

4) Mandatory access control (MAC) describes a system where every resource has access rules set for it all of the time.

5) A(n) Virtual Private Network (VPN) is a collection of protocols used to secure network traffic over a nonsecure network.

6) In IPsec, a security association is defined by a specific combination of Authentication Header (AH) and Encapsulating Security Payload (ESP).

7) The protection of the data portion of a packet is Content protection.

8) The protection of the header portion of a packet is Context protection.
