[IT] Security, FG有咩入行途徑?

今年computer science fresh grad, stream係讀security, 另外OS 同 network都有基本concept
上網睇完發覺好似得big4為主流, 想請教下, 除左big4仲有冇啲路數可以entry level入行? 例如做IT audit, compliance, pen test 果啲? 我見網上冇乜job post, 哩行應該冇咁傾向公開請人?

本身係 programmer. 但係對security好有興趣。想問課程內容有咩?
其實銀行嗰d一定要cyber security. 不過香港既it唔會分得好專, 可能要networking or programming 易入行d.

Big4算係叫做最易入
銀行好少請fg

security都係overall教返啲 network, OS, math 層面既security concept同實際既運作
例如[network] website certificate, digital signature in network communication, man in the middle attack, IPSec...
[math] password cracking, salt protection, algorithms, methods....
[OS] buffer overflow, command injection, SQL injection...
書本上其實就都仲有好多其他野, 唔知做野係要熟成點/熟D乜

留名 push

巴打最後入左行未？
