Overview
DoS attacks achieve their goal by flooding the target with traffic or sending it information that triggers a crash. While they don't typically result in data theft, they can cause significant disruption and financial loss.
Types of DoS
- Buffer Overflow Attacks: Sending more data than a system can handle.
- ICMP Flood (Ping Flood): Overwhelming a target with echo request packets.
- SYN Flood: Exploiting the TCP handshake process to consume server resources.
Prevention
- Firewalls and Routers: Filtering out malicious traffic.
- Intrusion Prevention Systems (IPS): Detecting and blocking attack patterns.
- Resource Limits: Configuring systems to handle only a certain amount of traffic.
