Principles of Network Security Security Management September 17‚ 2013 Contents Network Security Requirements With security mechanisms for the new network‚ management has asked for a report describing how the basics of a network operate and how two nodes communicate. With this we are going to break down the OSI model (Open Systems Interconnection) which is seven layers along with the TCP/IP (Transmission Control Protocol/Internet Protocol). After this the management

Abstract The objectives of the report are to investigate the perceived threats of computerized accounting information systems (CAIS) and to discuss how the impact of these threats can be reduced. The report covers the 19 perceived threats of CAIS‚ preventive controls‚ detective controls‚ corrective controls and auditors’ attestation of internal controls. Examples of controls given are authentication‚ authorization‚ physical access control‚ host and application hardening‚ encryption‚ training‚

Digital Signatures Requirements Message authentication protects two parties who exchange messages from any third party. However‚ it does not protect the two parties against each other. In situations where there is not complete trust between sender and receiver‚ something more than authentication is needed. The most attractive solution to this problem is the digital signature. The digital signature is analogous to the handwritten signature. It must have the following properties: •

incriminating. If suspicion is raised‚ then the goal of steganography is defeated. Since there is always a possibility that secret communication will be uncovered‚ steganography is often used together with cryptography. A steganographic message (the plaintext) is first encrypted by some modern encryption algorithms‚ and then a covertext is modified in some way to contain the encrypted message (the ciphertext)‚ resulting in stegotext. Digital Steganography A typical digital steganographic encoder is
