Study Notes
Denial of Service (DoS) Attacks
- Definition: A cyberattack aimed at making a network service unavailable by overwhelming it with traffic or exploiting vulnerabilities.
- Mechanism: Attacker sends excessive requests to a server, causing it to crash or become unresponsive.
- Example: Flooding a website with millions of requests.
- Impact: Website downtime, slowdowns, or crashes.
Distributed Denial of Service (DDoS) Attacks
- Definition: A sophisticated DoS attack where traffic originates from multiple sources, typically a network of compromised devices (botnet).
- Mechanism: Attacker uses a botnet to send massive requests to the target server.
- Example: Using thousands or even millions of infected IoT devices to overwhelm a website.
- Impact: Significant disruption to online services, loss of revenue, and damage to reputation.
Key Differences: DoS vs. DDoS
- DoS: Single source, one computer/server.
- DDoS: Multiple sources, distributed across many devices (botnet).
Mitigation Strategies
- DoS: Limiting requests from a single IP, using firewalls, and rate-limiting.
- DDoS: Specialized anti-DDoS services, cloud-based protections, and advanced traffic analysis tools to filter malicious traffic.
