NMAP (NETWORK MAPPER)

Nmap is short for network mapper. It is an open source security tool for network exploration, security scanning and auditing. However, nmap command comes with lots of options that can make the utility more robust and difficult to follow for new users. Nmap can be a valuable diagnostic tool for network administrators while they can be also a potent reconnaissance tool for the black-hat community (hackers, crackers, script kiddies, etc). Once the network is charted out using tools like lan mapshot, the nmap can be used to determine the type of services and hosts running in the network.So here it is a tutorial showing how to get things done....

VIRTUAL COMPUTING SIMPLIFIED

Unaware of the executable files!!! , don’t know coding!!! , don’t know how to check whether an exe a virus or trusted files, untested code, or untrusted programs from unverified third-parties, suppliers, untrusted users and untrusted websites. Viruses, Malwares, Rootkits, Backdoors and what not are not flowing on internet these days. How to choose which file to execute and which will not open a backdoor in my PC. Does one need to know coding language for that, and if so how many. I say today there is no need to know the coding to test whether an exe is a trusted file or a virus u can just execute it in a virtual environment and can’t test the behavior of the exe file. Let’s see how to do this

WPA ENCRYPTION DEMYSTIFIED

In your home, chances are that you have a wireless Wi-Fi router for your network. This router lets you connect things like your laptop and your iPad/iPhone/iPod to the network through Wi-Fi. Many people leave their Wi-Fi routers completely open with no security. This is a problem for two reasons:
1. Anyone who wants to can connect to your network and use your bandwidth. If they download something illegal (music files, child porn, etc.), it gets traced back to you rather than them. 

2. Given the right equipment, they can snoop on your network traffic and see all the data moving on your network.
Because of these two problems, people turn on encryption to secure their routers. WEP was the first encryption standard, but it has problems that make it not so secure. WPA is the second encryption standard and solved most of the problems with WEP. Therefore, people who are conscious of security and use it on their routers almost exclusively use WPA.
