How to secure your site against DDOS attack

The impact of Denial of Service (DoS) attack can be minimized if you take precaution against it. The following tips can help in minimizing the Denial of Service (DoS) attack.

• Monitor the server’s system performance and tabulate normal operating activity for disk, central processing unit(cpu), and network traffic. Monitor the server’s system performance to detect any deviation from up values.

• Monitor the amount of network packets and the type of nature that travel through your network or gateways.

• Update your software with any available update and always see reports from security organizations about any new threat.

• Implement network security devices which can detect any Denial of Service (DoS) attack.

• Record the details of any Denial of Service (DoS) attack to prevent future attacks. Log and report the following details.

1) The time of the attack

2) Your IP address at the time of attack

3) The attacker’s IP address

4) Other details and the nature of attack

A Distributed Denial of Service (DDoS) attack is a type of Denial of Service (DoS). In Distributed Denial of Service (DDoS) attack multiple systems flood the bandwidth or overload the resources of a targeted server.

In Distributed Denial of Service (DDoS), an intruder compromise one computer and make it Distributed Denial of Service (DDoS) master. Using this Distributed Denial of Service (DDoS) master, the intruder identifies and communicates with other systems that can be compromised. Then the intruder installs Distributed Denial of Service (DDoS) tools on all compromised systems. With a single command, the intrusion instructs the compromise computers to launch flood attacks against the target server. Here thousands of compromised computers are flooding or overloading the resources of the target server preventing the legitimate users from accessing the services offered by the server.
