Network security

FIT5044 – Network Security Week 6

Week 6 continued on the topic of firewalls. We got into some more detailed discussion about the implementation of the concept of firewalls. For example, the use of hardware/software and integration into the OS kernel etc. The question of where and how the firewall engine should be implemented generates a number of options. One thing to remember is that (all else being equal) a more secure configuration will result in less convenience for the business/users. The requirements in terms of security and convenience of each case must be the driving force behind decisions such as the FE implementation.

Next weeks lecture will be focussed on the IP layer and IP security. This week the focus for network security has been the RSA assignment so this is a short post!
