• Writing your own network sniffers and packet injection tools
• Writing plugins for Nessus, Ettercap, and Nikto
• Developing exploits for Metasploit
• Code analysis for web applications
• Writing kernel modules for security applications, and understanding rootkits

いいねぇ。ツールは今でも調べられます。Nessusはすでに使ってるから「Ettercap」「Nikto」「Metasploit」ぐらいか。
それにしても「Code analysis for web applications」をじっくり読むだけでも価値あるんとちゃうか？？
