One of the things I have been seeing a lot lately is a lot of people going Metasploit is better than Core and Core being better than Canvas and vise versa, the same for Nmap Portbunny and Unicorscan, and many other tools available out there. This type of thinking is a bit worrisome especially since the people that say this should be rational people that understand the working of the tools and their limitations and advantages. One of the first thing I was tough when learning about weapons is that never to call a weapon “Baby”, “Toy” or any other nick name just call it a tool, that lesson stuck with me for many things in my personal life and my professional life. Software and hardware are just tools each has it advantages and its drawbacks, the more tools one can master the more flexible one becomes, especially since you will be able to choose the right tool for the right moment and will also give you the ability to verify your results. No matter how good tools are they are written by human beings, heck this is the main reason for those of us that work in security have a job to do since humans are not perfect and we live from that imperfection, To this day I have not seen one single tool that does not generate a false positive or a false negative at any given time. This notion of mastering different tools is of great importance for a pentester in general since the engagement are not only limited in time but also limited in scope and have rules of engagement that limits him on what he can do, so having the flexibility to do the job in a fast and accurate manner is of great value. Not only should this apply to tools but also to operating systems, I have seen people who if it is not Linux it does not exist and the same on the Windows camp, there are time that when getting a tool on one system might take several steps longer on one are super simple on the other, virtualization has helped a lot to minimize this gap by allowing the user to have several operating systems to host his tools and to test before committing an action against a customer system. Mastering of the basics and the concepts makes the difference between being a script kiddy or a thru security professional, this mastery of the concepts and tools is what really gives the flexibility of choosing the right tool for the job.
