Advice on preventing DDoS attacks

/in /by

Distributed denial of service or DDoS attacks can cause important damage and monetary losses to companies. This is why today we’ll share a few words of advice on how to prevent DDoS attacks.

First of all, it’s worth noting that there are a few, more common, targets for attacks of this kind such as internet shopping sites, online casinos and any company or organization that depends on online services.

It’s important to prevent DDoS attacks because they can cause responses to requests in an infrastructure to slow down or even be ignored. In other words, even though a DDoS attack may not affect the infrastructure of a website, it will cause financial losses, in addition to drops in sales and audience unsatisfaction.

Preventing DDoS attacks to networks

Although it is normal to fear potential hacker attacks, it’s also important to pay attention to real traffic from visitors who are genuinely interested in visiting your website. So, let’s discuss a few actions to prevent DDoS attacks.

  1. Acquire an ISP (internet services provider):

Many ISPs offer DDoS attack prevention services, but you have to report the attack so your ISP can respond to the incident. This could mean up to 60 minutes delay for mitigation to begin.

  1. Local system:

One way of preventing these attacks consists in using an intrusion system, firewall technology and specialty hardware. Unfortunately, affected traffic is already in the network taking up valuable bandwidth.

  1. Using a Content Delivery Network (CDN):

This approach to prevent DDoS attacks minimizes corporate infrastructure exposure because IT can keep this infrastructure behind a content delivery network (CDN). If the organization subscribes to DNS and DDoS  mitigation, e-commerce sites, and the company itself can also be protected.

  1. Blackhole Routing:

This is one way to practically end all DDoS attacks. It’s about creating a blackhole route and concentrating all traffic on it. However, this route needs to be created with screening criteria, otherwise all traffic could be directed to that route throughout the entire attack.

  1. Rate limiting:

Rate limiting for a period can be another way to prevent DDoS attacks, although it is not very effective. This action does not keep traffic from performing basic actions, which in turn may lead to longer load time and consequently, to more failures.

  1. Web Application Firewall:

WAF is an effective strategy used in layer 7; in other words, between the internet network and supplier of origin, where WAF acts like a reverse proxy.

  1. Anycast network diffusion:

This approach uses unlimited diffusion to distribute attacking traffic through a network of distributed servers to the point where the network absorbs the traffic.

What tools to choose?

The answer to this question actually depends on both the size and the needs of your business. Nevertheless, preventing DDoS attacks is clearly necessary for company websites with a lot of user interaction.
