Hacking Class 7 - Vulnerability Scanning And Tools

In my previous class I have discussed about OS fingerprinting i.e finding that which OS the Victim is using.
Now We move further in scanning phase and now we will scan the systems for vulnerabilities i.e finding the weakness in security ,OS,database and so on..



What is Vulnerability???



As I have Told in First class that Vulnerability is weakness in the network,system,database etc... We can call vulnerability as the Loophole i.e through which victim can be attacked.. We first analyze the loophole and then try to use it to best to Hack the System of victim or oraganisation or website...


TOOL THAT WE USE FOR VULNERABILITY SCANNING ARE :
1. Nessus
2. Retina

Now After Scanning the Systems for Vulnerabilites .. We will Now Going to attack the Systems but before this we should know the Risk . This risk can be reduced to great extent by using Proxies.. In Next Class We will Discuss what are Proxies and How they work and how they are going to Help us and some undetectable and untraceable Proxy servers...
So wait For Next Class.... And Keep Learning...
