Network traffic analysis
In this section, we’ll be exploring commands in the Bash shell to capture and analyze network traffic.
Before I jumped into pentesting, I worked in various IT jobs. At one point, I earned the Cisco Certified Network Associate (CCNA) certification. The things I learned about networking and packet captures have been valuable in my pentesting career.
There will be times in your pentesting career when you’ll be faced with testing systems that have been repeatedly scanned and tested by others before you. At some point in time, you’ll either feel like you’re not good enough and question your ability, or think that there are no vulnerabilities present. When this happens, you’ll be forced to dig deeper and think outside the box to uncover vulnerabilities that others have overlooked. Understanding networking at a deeper level can frequently be the key to uncovering these vulnerabilities.
