Backing Up Defenses against DDOS Attacks

Backing Up Defenses against DDOS Attacks

Examples of legitimate tools used are helping, socket programming, and httping. There are also underground tools available for such attacks.

DDoS stands for Distributed Denial of Service. DDoS is a DOS attack where multiple compromised systems, often infected with a Trojan, target a single system causing a Denial of Service (DoS) attack. This kind of attack tries to make a computer resource unavailable to users.

DDOS attacks

Signs of a DDoS attack

• The US Computer Emergency Response Team defines symptoms of a DDoS attack as.

• Unusually slow network performance, either processes or opening files. Unavailability of a website.

• Inability to access a website. The dramatic increase in spam emails; this is an email bomb.

• DDoS attacks lead to issues with branches of a network being attacked. The attack overloads the network; other branches will try to compensate for the increase in traffic.

• This causes the whole network to slow down. A large enough attack can shut down entire regions of internet connectivity.

The DDoS attack may also use malware to cause further damage.

• Max out the processor’s usage so no work gets done

• Cause Microcode errors in the machine

• Lock up the computer by giving the processor erroneous sequencing

• Crashing the operating system itself.

Defending against DDoS attacks

• Recognize the signs of a DDoS attack. The first and best defence against a DDoS attack is recognising it early. Unfortunately, not all DDoS attacks are easy to distinguish from normal spikes in the network or web traffic or a sudden slowdown in network performance.

• DDoS attacks can take a website down quickly and emphatically. By knowing what you are facing, you can defend against them.

• DDoS Attacks range from brute force incursions to surgical strikes against key components of a network. The right tools to set up defences and a DDoS attack can be stopped cold.

Conclusion

Consider our advice to help prevent attackers from shutting down your network with unwanted traffic. Have an incident response plan in place and talk about DDoS countermeasures in advance with your ISP and a service provider specialising in mitigating these attacks.

Frequently Asked Questions

Q1. What is the most effective way to stop a DDoS attack?

The most effective protection against all DDoS attacks is a Web Application Firewall (WAF), which actively blocks malicious traffic that seeks to exploit vulnerabilities within the application.

Q2. What is the largest DDoS attack mitigated?

The largest reported HTTP DDoS attack reached a staggering rate of over 71 million requests per second (fps), making it the most significant attack.

Q3. What is the difference between DDoS and DoS?

A server is overwhelmed with traffic in a denial-of-service (DoS) attack, rendering a website or resource inaccessible. In a distributed denial-of-service (DDoS) attack, multiple computers or machines are utilized to flood the targeted resource with traffic.
