Protecting Against Cyber Attacks & Threats

DoS/ DDoS Mitigation

If you’re running a commercial website or online applications (e.g., SaaS applications, online banking, e-commerce), you probably need 24×7, always-on DDoS protection. Speak with an expert by calling 877-708-8900.

In a DoS attack, a perpetrator uses a single Internet connection to either exploit a software vulnerability or flood a target with fake requests—usually to exhaust server resources (e.g., RAM and CPU).

Distributed denial of service (DDoS) attacks are launched from multiple connected devices that are distributed across the Internet. These multi-person, multi-device barrages are generally harder to deflect, mostly due to the sheer volume of devices involved. Unlike single-source DoS attacks, DDoS assaults tend to target the network infrastructure to saturate it with huge volumes of traffic.

DoS/ DDoS Mitigation Solutions

Better Accessibility

The first step in preparing your business to deal with a DDoS incident is to assess your risk. Important basic questions include:

Which infrastructure assets need protection?
What are the soft spots, or single points of failure?
What is required to take them down?
How and when will you know you’re targeted? Will it be too late?
What are the impacts (financial and otherwise) of an extended outage?

Armed with this information, it’s then time to prioritize your concerns, examining various mitigation options within the framework of your security budget.

If you’re running a commercial website or online applications (e.g., SaaS applications, online banking, e-commerce), you’re probably going to want 24×7, always-on protection. A large law firm, on the other hand, may be more interested in protecting its infrastructure—including email servers, FTP servers, and back office platforms—than its website. This type of business may opt for an ”on demand“ solution.

The second step is to choose the method of deployment. The most common and effective way to deploy on-demand DDoS protection for your core infrastructure services across an entire subnet is via border gateway protocol (BGP) routing. However, this will only work on demand, requiring you to manually activate the security solution in case of an attack.

Consequently, if you’re in need of an always-on DDoS protection for your web application, you should use DNS redirection to reroute all website traffic (HTTP/HTTPS) through your DDoS protection provider’s network (usually integrated with a content delivery network,). The advantage of this solution is that most CDNs offer on-call scalability to absorb volumetric attacks, at the same time minimizing latency and accelerating content delivery.
