DDoS Attacks

A Distributed Denial of Service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic.

Types of DDoS Attacks

• Volume-based Attacks: Includes UDP floods, ICMP floods, and other spoofed-packet floods. The attack's goal is to saturate the bandwidth of the attacked site.
• Protocol Attacks: Includes SYN floods, fragmented packet attacks, Ping of Death, and Smurf DDoS. This type of attack consumes actual server resources, or those of intermediate communication equipment.
• Application Layer Attacks: Includes low-and-slow attacks, GET/POST floods, attacks that target Apache, Windows or OpenBSD vulnerabilities and more. The goal of these attacks is to crash the web server.
• Amplification Attacks: Involves the attacker sending small requests to a server that generates a much larger response, amplifying the amount of traffic sent to the victim.

• Implement robust network security measures
• Use DDoS mitigation services or appliances
• Configure firewalls and routers to filter traffic
• Develop an incident response plan
• Regularly update and patch systems
• Monitor network traffic for anomalies
• Implement rate limiting and traffic shaping
• Use Content Delivery Networks (CDNs) to distribute traffic
