DDoS Protection

DDoS protection is an essential part of a cybersecurity strategy. Denial of service attacks have become a primary cybersecurity threat facing enterprises.

DDoS Protection

DDoS protection and learning how to protect from DDoS attacks must 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 denial of service protection can eliminate or minimize downtime from a DDoS attack.

DDoS protection 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. Every organization with a valued web presence needs to know how to protect against DDoS attacks.

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 ensure protection from DDoS botnets.

DDoS protection is needed for all types of DDoS attacks

Different types of DDoS attacks can affect specific IT network elements and require different DDoS mitigation techniques for denial of service DoS protection. Attackers know this and will identify the weak links in a DoS attack protection 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 protection strategy

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

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

Big data and DDoS protection

Hundreds of millions of data points in multiple streams pour into a DDoS protection network in real time during an attack. Automatic DDoS protection software with decision-making algorithms based on data analytics for DDoS protection are helpful but are prone to false positives. DDoS protection experts in a security operations center quickly make sense of the deluge of data and make precise decisions as to which data/traffic to allow and which to block. Using big data, security operations center engineers can customize your DDoS defense using specialized knowledge of how to protect against DDoS attack types observed as the attack happens.

How to protect from DDoS panic: a playbook

A best practice for DDoS protection is the creation of a playbook or runbook that details a planned response when a DDoS attack occurs. Companies work with their DDoS protection 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.
