How to Fight with DoS Attack
A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. DoS attacks are fast becoming the weapon of choice for hackers. However, you can take the following measures to counter these attacks.
- Disable unused or unneeded network services.
- Maintain regular backups.
- Create, maintain, and monitor daily logs.
- Create appropriate password policies.
- Implement an Intrusion Detection System.
- Implement route filters to filter fragmented ICMP packets.
- Keep a strict vigil on the physical security of your network resources.
- Configure filters for IP-spoofed packets.
- Install patches and fixes for TCP SYN attacks.
- Partition the file system to separate application-specific files from regular data.
- Deploy tools such as Tripwire that detect changes in configuration information or other files.
