You already know that if you want to lock down your Wi-Fi network, you should opt for WPA encryption because WEP is easy to crack. But did you know how easy? Take a look. Note: This post demonstrates how to crack WEP passwords, an older and less often used network security protocol.
A properly designed subnet can do wonders for the security and performance of a network. The main idea in subnetting is to divide a network into smaller pieces, which we call subnets. Actually implementing a subnet is typically more difficult than simply using the default subnet mask of 255.255.255.0. This usually means that temporary or smaller networks do not need to be subnetted.
The TechRepublic CIO50 list celebrates the most influential and innovative tech chiefs, voted by their fellow CIOs SSH is an extremely useful tool in that it allows you to do many things in a secure fashion that you might not otherwise be able to do. One of the things SSH allows you to do is to set up a reverse encrypted tunnel for data transfer.
Besides the fact that I am studying for another Microsoft test and staring at subnets all day long – I also get asked on a regular basis how many addresses can i get from a /24 subnet or what does 255.255.255.0 mean. Let me break it down for you real quick like: When you use 255.255.255.0 as your subnet you are limiting yourself to a network containing all the same ip’s except for the last number. Like 192.168.1.0 where the 0 changes.
