The -sS option is telling Nmap that it should also scan TCP ports using SYN packets. Same as the regular Intense scan, just that we will also scan UDP ports (-sU). This comes from having a pretty fast timing template (-T4) and for using the -A option which will try determine services, versions and OS. With the verbose output (-v) it will also give us a lot of feedback as Nmap makes progress in the scan. It will make an effort in determining the OS type and what services and their versions are running. Should be reasonable quick, scan the most common TCP ports. The presetsīefore we go into the different options in use I will make a brief explanation of each of the presets that come with Zenmap. Big thanks to Fyodor for creating and maintaining such awesome software. Nmap was created by Fyodor (Gordon Lyon, twitter, about) and has been actively developed since 1997. Some of the scan types are kind of obvious, however they may not be to everyone. It comes pre loaded with 10 different scan types which we will take closer look at them in this article.

I find it extremely motivating and fun to teach others the art of security and hacking, and I often find that my passion and enthusiasm rubs off on my students. This course prepares you for the GIAC Certification in Incident Handling (GCIH). My primary class I am teaching is Hacking Techniques, Exploits & Incident Handling. I consider myself a pragmatic person, with the ability to think outside the box, keeping the business in focus. I am passionate about security, both IT and physical security, which is one of the reasons I do a lot of public speaking at different events such as classes, conferences and workshops.ĭriven by mottos such as "Magic is just science we don't understand yet" and "Think bad, do good", I attack today's security challenges with eagerness and enthusiasm. I am usually enthusiastic and motivating when I work, and usually positive and optimistic about the general problems I encounter. I am an open, sharing and engaging person to be around, some even think I'm funny. Having a vast and broad experience in IT certainly help a great deal when working penetration tests and incidents. Along with my security expertise, I have a background from system development and application management. I'm Chris Dale from Norway, founder and principal consultant at River Security ().
