Example text

A practical method for establishing a shared secret over an unprotected communications channel was needed C. an iterated HMAC function to generate pseudorandom data streams was needed D. to provide a scalable and secure mechanism for distributing, managing, and revoking encryption and identity information Answer: B Explanation: The Diffie-Hellman (D-H) key agreement is a public key encryption method that provides a way for two IPSec peers to establish a shared secret key that only they know, although they are communicating over an insecure channel.

Each statement defines a pattern that would be found in an IP packet. As each packet comes through an interface with an associated access list, the list is scanned from top to bottom and in the exact order in which it was entered, for a pattern that matches the incoming packet. A permit or deny rule associated with the pattern determines the fate of that packet. Cisco uses access lists as packet filters to decide which packets can access a router service or which packets can be allowed across an interface.

The security features provided in SNMPv3 are: Message integrity-Ensuring that a packet has not been tampered with in-transit. Authentication-Determining the message is from a valid source. Encryption-Scrambling the contents of a packet prevent it from being seen by an unauthorized source. SNMPv3 provides for both security models and security levels. A security model is an authentication strategy that is set up for a user and the group in which the user resides. A security level is the permitted level of security within a security model.
