DDoS Mitigation

DDoS mitigation is an essential part of a cybersecurity strategy. Mitigating DDoS attacks can allow your site to remain active during denial of service attacks.

DDoS Mitigation

DDoS mitigation and a DDoS defense plan for mitigating DDoS attacks should be at the core of a successful cybersecurity strategy, because distributed denial of service (DDoS) attacks have become one of the primary cybersecurity threats facing enterprises. DDoS attacks are attempts to make a computer resource (i.e. website, e-mail, VoIP, or a whole network) unavailable to its intended users. Overwhelmed with massive amounts of unsolicited data and/or requests, the target system either responds so slowly as to be unusable or crashes completely. Effective DDoS mitigation can eliminate or minimize downtime from a DDoS attack.


DDoS mitigation protects from cyber-attack groups and DDoS botnets

Organized cyber-attack groups, such as Anonymous, frequently launch politically-motivated denial of service attacks to cause website downtime for big brand corporations, financial services companies, and even governments. Yet every day there are hundreds of other unpublicized DDoS attacks on ecommerce companies and web-based service providers of all sizes.

The data volumes required to create denial of service outages are easily achieved by a network of remotely controlled zombie or botnet (robot network) computers or devices. These machines have fallen under the control of an attacker, generally as a result of infection from a Trojan virus. It is important to have a DDoS defense plan to mitigate DDoS attacks from botnets.

DDoS mitigation for all types of DDoS attacks

Different types of DDoS attacks can affect specific IT network elements and require different DDoS mitigation techniques. Attackers know this and will identify the weak links in a DDoS attack mitigation strategy and chose the DDoS attack they determine will cause the most damage. For example:

  • An application-layer DDoS attack may not disrupt routers, but it can penetrate deeply into load balancers, applications and databases.
  • A high packet-per-second SYN flood may affect servers and routers.
  • A high packet-per-second UDP flood may only cause issues with routers.

Your DDoS mitigation strategy

DDoS mitigation is a cybersecurity response to block a DDoS attack – it seeks to prevent a DDoS attack from damaging the operations of your enterprise. A DDoS mitigation service is designed to detect, monitor and block DDoS attacks. Given the growing number and scale of DDoS attacks, planning for DDoS attack mitigation is a critical IT security function.

It is virtually impossible for an individual business to build out a sufficiently large DDoS mitigation network to scale in response to a large DDoS attack. Cloud-based DDoS mitigation offers built-in scalability and global reach combined with advanced DDoS detection techniques, specialized DDoS mitigation software, and DDoS mitigation experts who know how to mitigate DDoS attacks.


Big data and DDoS mitigation

Hundreds of millions of data points in multiple streams pour into a DDoS mitigation network in real time during an attack. Automatic DDoS mitigation software with decision-making algorithms based on data analytics are helpful but are prone to false positives. DDoS mitigation experts quickly make sense of the deluge of data and make precise decisions as to DDoS mitigation techniques to deploy and which data/traffic to allow and which to block. Using big data, they can customize your DDoS defense with specialized knowledge of how to mitigate DDoS attack types observed as the attack occurs.


A playbook to deploy DDoS mitigation

A best practice for deploying DDoS mitigation is the creation of a playbook or runbook that details a planned response when a DDoS attack occurs. Companies work with their DDoS mitigation service provider to create a simulated DDoS attack, much like a military training drill in which no live ammunition is used. The exercise helps management see the best way to manage internal and external communications when confronted with a DDoS attack. Following this exercise, optimizations may be developed to ensure a rapid, repeatable and predictable plan for DDoS survival.
