Information security is concerned with the protection of information, which can be stored, processed or transmitted within the organizations critical information systems, against loss of confidentiality, integrity or availability. Protection measures to prevent these problems result through the implementa- tion of controls at several dimensions: An always vital objective for military organizations is to ensure superiority, in- cluding in contexts of information warfare and competitive intelligence.
However, it is expected that answers to the assignment questions be succinct i. Instructions Answer the following questions: Explain the significance of the key characteristics of information, namely the CIA, to information security.
Preserving confidentiality, integrity and availability of data is a restatement of the concern over interruption, interception, modification and fabrication. How do the first three concepts relate to the last four?
What are the significant differences? How do these standards reflect a changed environment many years after Shannon wrote his standards? Security decision making should be based on rational thinking and sound judgement. In this context critique five security design principles. A synchronous password token has to operate at the same pace as the receiver.
That is, the token has to advance to the next random number at the same time the receiver advances. Over time the accumulated difference can be significant.
Suggest a means by which the receiver can detect and compensate for clock drift on the part of the token.
Can link and end-to-end encryption both be used on the same communication? What would be the advantage of that? Cite a situation in which both forms of encryption might be desirable. This assignment is designed to test your knowledge and understanding of some of the key concepts and issues related to information security as covered in the Module 1 of this subject.
All questions are of equal value.

Examples of active attacks are: Interruption Modification Fabrication(DOS) Replay attacks The classification of network attacks described above can be summarized in Table 1.
The four general classs of onslaughts are Interruption, Interception, Modification, and Fabrication. These onslaughts are categorized in footings of active onslaughts and inactive onslaughts. Passive Attacks: Passive onslaughts mean the eavesdropping on, or monitoring of transmittals.
