Encryption as a Component of Operating System Security

Encryption is used in a variety of ways to support different aspects of operating system security. One important example is the use of encryption to prevent passwords being transmitted across the network from being compromised by anyone able to monitor packets on the network.

Use the study materials and engage in any research necessary to fill in knowledge gaps. Discuss the following:

· Identify an operating system security control that uses encryption as a functional component of the control.

· Describe how encryption contributes to the successful operation of the operating system control.

· Identify how encryption can be used to defeat exploits that use inference and aggregation to identify patterns in traffic.

Evolution of Encryption

Cryptography has been around since ancient times, when coded messages were sent by courier from sender to recipient. Modern encryption uses mathematical algorithms as the basis for how it functions; however, as computing power increases the need for more robust encryption has been the hallmark of that evolution. Common encryption solutions have much larger key lengths as one of the enhancements over earlier solutions such as DES.

Use the study materials and engage in any additional research needed to fill in knowledge gaps. Discuss the following:

· Describe the primary differences that have occurred in the evolution of encryption from DES through AES.

· Explain one political controversy involving encryption that is a part of the historical evolution of encryption.

· Determine strategies to ensure that encryption is used appropriately to protect operating system and application security within an organization.
