- Core dimensions of Denial of Service (DoS) attacks, including how attacks differ in duration, sophistication, and resource usage.
- Persistent vs. transient attacks:
- Persistent attacks cause long-lasting damage that requires manual intervention (e.g., disk exhaustion, battery drain).
- Transient attacks only impact the system while the attack is active (e.g., network flooding, CPU exhaustion).
- Naive vs. clever attack strategies:
- Naive attacks rely on high traffic volume to overwhelm systems.
- Clever attacks exploit inefficiencies to force targets into heavy processing, such as:
- Triggering complex database queries
- Exploiting asymmetric cryptographic operations
- Abusing application logic
- Native vs. amplified attacks:
- Native attacks depend solely on the attacker’s own resources.
- Amplified attacks leverage third-party services to significantly increase attack impact.
- Amplification techniques, including abuse of services like Memcached, where a small request can generate an extremely large response toward the victim.
- Evolution of modern attacks, where attackers increasingly:
- Use efficiency over brute force
- Leverage publicly available tools and knowledge
- Create disproportionate impact with minimal effort
