Network Security Experts would in demand as more and more enterprise VPNs is connecting to the Internet as same as the various commercial services. But you should have EXTENSIVE and PROFOUND knowledge

cute(cute)
in OSs and programming. A attacker can invade a certain network at a chance but Security Experts must can prevent any kinds of attacks. When I was working as a Unix network administrator, my friend, a talent university guy, invaded my Internet PPP server by using a software loaded from Internet although he knew nothing of Unix at that time. In my opinion a practicable way is to train yourself to be a real Security Expert which requires a excellent network environment to practice and your talent. Checkpoint and Cisco Firewall are nothing because they give you a friendly user interface to implement the rules. If your English is excellent and expecting a good luck in your future job seeking you can try the easy way.

      • 考个CCIP或者CISCO QUALIFIED SPECIALIST - SECURITY现在比较吃香（相对其他CCNP/CCDP而言） -avacao(吃草的大老虎白白胖胖); 2001-11-18 (#266466@0)
      • "a talent university guy, invaded my Internet PPP server by using a software loaded from Internet although he knew nothing of Unix at that time" -- That's called a script kiddy, not a real hacker. -dennis2(Dennis); 2001-11-18 (#266496@0)
        • I cannot agree with you more but did I entitle him as a hacker? -cute(cute); 2001-11-18 (#266508@0)
          • No, you didn't. I was just being picky again :-) -dennis2(Dennis); 2001-11-20 (#267899@0)
