So I have further evidence that I might be crazy: I have decided to abandon any and all CCIE DC studies. Why you might ask? Simple: I dont have access to the required equipment continually so I can practice and reinforce any knowledge.

It seems like every day, there are some vulnerability or crack announced on the geek news-outlets. For some reason, the recent publication of an exploit of a flaw in the SSL/TLS implementation in some versions, made me extra curious and it made me think a little harder about this whole security business.

In this small post i want to clarify the use of the “ip verify” command. There has been some confusion on the usage of this command, especially in conjunction with the access-list parameter. I would like to clarify this here.

In this article i will try and setup a very simple example using Cisco IOS IPS (Intrusion Prevention System). As before, a simple topology consisting of 3 routers will suffice. They are configured as follows: Topology for IPS example. R1 will act as our source host.

This small post will be about a little feature called “views”. This feature is used to create a sort of profile, for which you could have a certain user do certain things. As you might know, the only way to do this previously was to use the priviledge level command.
