DoS and DDoS Attacks
Context
Recently, Elon Musk hosted a live audio interview with former US President and Republican Presidential candidate Donald Trump on the social media platform X. The event faced a 40-minute delay and technical issues, which Musk attributed to a “massive DDoS attack” on the platform.
About DoS and DDoS Attacks:
- Denial-of-Service (DoS) Attack: A DoS attack targets a website or online service to make it unavailable by overwhelming it with excessive requests or data. It floods the target server with a high volume of traffic, which can slow down or halt its functionality, making it inaccessible to legitimate users.
- Distributed Denial-of-Service (DDoS) Attack: A DDoS attack involves multiple systems working together to launch a coordinated attack on a single target. It utilizes a network of compromised computers (botnets) to generate traffic or requests from multiple sources, complicating the process of identifying and stopping the attack.
- Types of Attacks:
- Smurf Attack: Involves sending ICMP packets with a spoofed IP address, causing the target system to flood itself with responses.
- SYN Flood: Exploits the TCP handshake process by sending incomplete connection requests, overloading the server with half-open connections.
- Signs and Mitigation:
-
- Signs: Slowed internet speeds, difficulty accessing services, and overall system unresponsiveness.
- Mitigation: Firewalls, intrusion detection systems, and network monitoring tools can help identify and mitigate DoS/DDoS attacks by filtering malicious traffic and ensuring the availability of online services.
