What are the must have tools for an information security professional? I have been reading about infosec for more than two years. I came to know that linux distributions like Kali and Backtrack are good for penetration testing and related information forensic tasks. I planned for getting certified Cisco security certifications.But I would like to learn the basic concepts before joining certification programs. So what should I do to get into Information Security? Here at Mississauga, companies like NCI offers training on information security practices. Is that enough? Looking forward to get some advice.
