DDoS Attacks: Definition, Risks & Protection

In this blog, our Chairman of the Board of Teichmann International (IT Solutions) AG Dr Fabian Teichmann discusses the threat of DDoS attacks and the importance of preparation before the fact, and the critical role of communication in a crisis.

Today we're diving into the world of DDoS attacks - a major threat in the cyber landscape. Let's break down what DDoS attacks are and how they can cripple systems. DDoS or Distributed Denial of Service is an onslaught where multiple systems flood a target’s network with traffic, overwhelming it to the point of inaccessibility. Imagine thousands of knocks on a door simultaneously blocking legitimate visitors from entering. Cyber criminals use a network of infected devices known as a botnet to launch these attacks. Each device acts as a puppet bombarding the target with requests causing legitimate traffic to grind to a halt. Websites go down, services become unavailable and the damage can be staggering.

Preparation is key: by understanding these attacks and implementing strong security measures, we can protect our digital infrastructures. Remember, in this digital age resilience against cyber threats like DDoS is not just an option, it's imperative. Despite our best efforts, DDoS attacks can still breach our defenses.

If you find yourself under attack, here's how to respond effectively:

• Firstly, don't panic. Quick and calm reaction is vital. Immediately inform your IT team or cyber security provider. They can start diagnosing the extent of the attack and begin mitigation processes.
• Next activate your incident response plan. This should include measures like rerouting traffic, filtering out malicious packets, and scaling up bandwidth to absorb the influx. Communication is key: during this time keep stakeholders informed about the status and expected resolution time.
• It's also crucial to identify the type of DDoS attack, whether it's volume based, protocol, application layer - each requires a different response strategy. Your cyber security team can use the information to apply specific counter measures.
• After the attack conduct a thorough analysis. Review: how the attack happened; the effectiveness of your response; and any system vulnerabilities that were exploited. This review is essential for strengthening your defenses and preventing future incidents.
• Lastly, consider reporting the attack to law enforcement and relevant cyber crime agencies. Sharing information about the attack can help authorities track down the perpetrators and prevent future attacks on others.
