A website has many vulnerabilities, and should be tested on a regular basis. Join Lisa Bock as she reviews Nikto, an Open Source web server scanner built into Kali Linux. View a short demo to test for a variety of vulnerabilities, such as outdated versions of servers, version specific problems, missing headers, dangerous files and CGIs.
- [Voiceover] A website has many vulnerabilities,…and should be tested on a regular basis.…Web server scanning conducts a black box test…in that they do not access the source code…on a web application,…but they're able to identify security vulnerabilities.…Nikto is built in to Kali Linux,…and is an open-source web server scanner.…It performs complete testing on web servers…for a variety of vulnerabilities,…such as outdated versions of servers,…version-specific problems, missing headers,…such as anti-clickjacking X frame options header,…and dangerous files and CGIs.…
Now, I'm in Kali Linux.…I could go into vulnerability analysis,…and as you can see here,…Nikto is available for me to just launch,…but it's also available if I simply open a terminal.…Now, for us to do a quick scan,…which is what I'm going to do is checkscanme.nmap.org,…but first I'll need the IP address of scanme.nmap.org,…so we'll do nslookup,…and now I have the IP address of scanme.nmap.org.…
Now, I'll type nikto -H,…and the IP address,…and we'll allow it to run.…
This course investigates the scanning tools and techniques used to obtain information from a target system, including specially crafted packets, TCP flags, UDP scans, and ping sweeps. Lisa Bock discusses how hackers can identify live systems via protocols, blueprint a network, and perform a vulnerability scan to find weaknesses. She also introduces some of the tools and techniques that hackers use to counter detection via evasion, concealment, and spoofing. In addition, learn how to reduce the threat of tunneling, a method hackers use to circumvent network security.
Note: The Ethical Hacking series maps to the 20 parts of the EC-Council Certified Ethical Hacker (CEH) exam (312_50) version 10.
