How to Build a DDoS Response Plan in 7 Steps

If you don’t have a DDoS attack plan, it’s probably time to bump it up to the top

Published By - WisdomPlexus

You’ve probably heard about distributed denial of service (DDoS) attacks, or maybe you’ve even been hit by one. If you’re like most organizations, you’ve already been DDoSed.

If you don’t have a DDoS attack plan, it’s probably time to bump it up. That’s because DDoS attacks are getting bigger, persistent, and more harmful. They inflict serious cost in terms of lost revenue, damaged systems and lost consumer trust. DDoS is no longer just a web server problem; infrastructure is now a target.Here are seven steps to building a DDoS response plan.

  1. Build a DDoS Response Team

    The first step is to identify the various people and departments within your organization. These people will be in charge of both planning and execution. Your team must fulfill a range of tasks. From identifying and mitigating an attack to coordinating with ISPs, notifying customers and communicating with the press.

  2. Create a Response Plan

    The purpose of your response plan is to define various resources, tools and procedures. These are required to minimize the risk and costs of a DDoS incident before it happens. It should include topics such as risk assessment, organizational roles and responsibilities.

  3. Assess Your Risk of an Attack

    It’s imperative to understand the scope of your risk. Which infrastructure assets need protection? What is the cost of a given asset becoming unavailable? You can estimate the cost of an extended outage in terms of lost revenue and resources. Also, you need to evaluate the risk of an outage.

  4. Identify Single Points of Failure

    Another important part of risk assessment is the identification of single points of failure. Even if your online systems are protected, a successful attack against your DNS server can render it unavailable.

  5. Strategize with Your ISP

    It’s important to clearly communicate with your Internet service provider (ISP) as part of your DDoS response preparation. In large attacks that can completely strangle your bandwidth, your ISP has no choice but to intervene.

  6. Check Your DNS TTLs

    Time to live (TTL) is the value determining how long a piece of data is valid. Furthermore, TTL limits how long your current DNS settings are cached with ISPs. If your website’s TTL is set at three hours, other DNS servers won’t bother checking for a DNS update. A lower TTL equates to a faster reaction.

  7. Test and Maintain

    As time goes by, you introduce new websites and applications. Your DDoS protection provider periodically updates its systems. Similarly it’s important to check the impact of these changes on your readiness.

Malicious DDoS attacks have become a fact of life for almost all organizations, but a well organized plan and a DDoS mitigation solution will keep the attackers from causing you significant harm.
