Help Defeat Denial of Service Attacks: Step-by-Ste

Organizations that operate networks connected to the Internet may be serving as unwitting participants in Denial of Service (DoS) Attacks like those that hit many organizations in early February, 2000.

You can act now to reduce the chances that your network could be used to damage other networks if you implement the following two steps.

• Egress Filtering to Stop Spoofed IP Packets from Leaving Your Network
• Stop Your Network from Being Used as a Broadcast Amplification Site

These two steps should be implemented immediately, and detailed instructions for doing this are provided below. Broad application of these two steps can significantly reduce the threat posed by DoS Attacks.
