Does anyone really feel good about Desean Jackson ? I mean I have marquise Lee in the lineup over him now , so I really want someone to feel good about Jackson to sell me too <| sep |> 1 . Correct , they generate tons of network and host traffic that almost any security monitoring software will freak out about . 2 . I ' ve never done pentesting but I did manage the vulnerability management program for a medium sized company . We used something like this to identify vulnerabilities that could potentially be exploited and used the data generated to improve our updating and patching processes . We had firewall and monitoring rules explicitly set up to allow and not alert on these scans . I suspect you ' re right , a pentester or malicious hacker would need to show more finesse . 3 . We used Qualys and they have some pretty good training videos and articles on their website that are free I think . You can also get a trial scanner free I believe . I think Rapid 7 vulnerability scanner is somewhat common too . Not sure about others . 4 . I guess I already sort of answered this , but yes , from an inside , preventative side , not necessarily a penetration side . Sorry , I ' m not a super expert but no one else had answered so I figured I ' d throw out what I know . Thanks for the excellent question , this type of stuff is why I subscribed .
