Network Security Ph.D.

The weekly assignment, which covered various security-related topics, necessitated that we, as students, research the assigned topics, engaged with the material and, importantly, explore the multi-dimensional nature of network security. Added to that, weekly feedback on assignments offered us a clear indication of the topics which we could handle well and those which we could not.

The act of maintaining the integrity of a network is the act of preventing authorized users of the system from making changes beyond their authority, and to prevent unauthorized persons from making changes at all. If the integrity of a ...Show more

Summary

One of the most important issues confronting network administrators and, indeed, any individual or entity connected to a network is security. While not wanting to exaggerate the dimensions of the security problem, the fact is that every second of connectivity could mean vulnerability to attack or unauthorized access…
