How to Keep A Dedicated Server High In Security Protection against any attack ? many people attacks with many tools as well as ddos attack... how to prevent any type of attack
You need a dedicated server provider that offers DDoS protection, also probably a management company to keep everything secure and install tools to protect you. But software wise, there isn't much you can do against DDoS attacks when they get big.
You should hire a sys admin sorry if you dont know the system well you cant prevent a ddos attack, if you can't compile a kernel you cant find a solution to kernel based leaks.
please explain more carefully in details......... if there so prevention for ddos attack then whats the point of system admin?
