DDoS attacks are currently an overlooked residual risk for most businesses. Most businesses are worried about ransomware attacks that take months to develop; however, DDoS attacks can happen quickly and cause a complete business outage.
Organizations have altered their processes to support a remote workforce while maintaining efficiency during the last two years, and the way people work has accelerated into the digital environment. This shift put a greater emphasis on connectivity and the security and performance of enterprise networks, not only to drive business results but also to protect against malicious actors trying to profit from business disruption.
Distributed Denial-of-Service (DDoS) attacks are one of the most common and serious risks to any organization that operates a distributed workforce model, and they are becoming larger and more frequent.
Any outage or increased delay in today’s digitally-focused world can harm brand reputation, consumer trust, and, eventually, revenue generation. Businesses must realize that DDoS attacks aren’t just a blip on the radar; if mishandled, they may damage a company’s long-term prospects.
Strategies to Mitigate DDoS Attacks
Though there is no way of preventing a hacker from launching a DDoS attack, adequate preparation and preventative steps can help mitigate the threat and impact of such an attack.
Bandwidth Should Be Increased
Making the hosting infrastructures DDoS resistant is one of the most fundamental steps companies can take to protect themselves against DDoS attacks. This means they have enough bandwidth set aside to deal with traffic spikes caused by cyber-attacks.
However, purchasing more bandwidth is not a proper response to preventing DDoS attacks. Businesses can raise the bar that attackers must surpass before launching a successful DDoS attack by increasing bandwidth, but they should always integrate this with other mitigation strategies to be entirely safe.

Responses Can Be Outsourced
Enterprises can outsource their responses to specialized firms, Internet Service Providers, or both. These types of partnerships must be established before an attack. If one occurs, mitigation is as simple as contacting the ISP or service provider to activate protection or keep protection turned on at all times.
The DDoS protection service will often redirect traffic to their environment. This can be done through DNS, by changing the A record to reflect an IP that the DDoS provider has assigned, or through Border Gateway Protocol (BGP), by advertising a more precise route than the one that is now published.
Build Robust and Resilient Architecture
Architecting systems to be resilient requires a comprehensive business continuity plan, with DDoS as a component of that plan.
When designing data centers and networks for DDoS protection, the same criteria apply when designing for business continuity. Businesses strive to minimize single points of failure or bottlenecks by utilizing geographically varied networks and providers.
One option to improve DDoS response is to use Content Distribution Networks (CDNs), which provide a globally distributed network of proxy servers that can massively enhance resilience.
In comparison to previous models, cloud architecture is a vast improvement. It enables businesses of any size to set up fully redundant systems that can be turned on and off at the touch of a button. It also provides a low-cost, regionally varied infrastructure and a simple, low-cost approach to scaling load capacity up and down.
