How to prevent DDoS? Which solution is the most optimal?

What is DDoS?

DDoS (Distributed Denial of Service) is a cyber attack that causes system overload. Hackers send a large number of requests from many various different sources, this overloads the server and causes services to stop working. DDoS aims to slow down or disrupt services, hinder legitimate visitors and cause damage to the business or organization.

How to prevent DDoS? Top 7 solutions to prevent DDoS attacks

There are 7 popular DDoS prevention methods used by administrators and server owners:

Firewall and Security Devices:

Using security appliances such as firewalls, intrusion detection systems (IDSs), and intrusion prevention systems (IPS) to control and block suspicious traffic from unknown sources.

Broadband and CDN Service:

Increasing network bandwidth and using CDN (Content Delivery Network) services to distribute the payload and minimize the impact of the attack on the main server.

IP Address Filter:

Configuring filters to block traffic from IP addresses identified as attack sources. However, this solution can’t be applied if hackers use a botnet with thousands of different IP addresses.

Use Anti-DDoS Solution:

There are many specialized security solutions against DDoS attacks. These include anti-DDoS services from cybersecurity vendors or deploying anti-DDoS equipment in the network infrastructure.

Load Balancing:

Using load balancing solutions to distribute traffic to many different servers, reduces the risk of the main server being overloaded due to a DDoS attack.

Monitoring and Early Detection:

Implementing continuous monitoring to detect early manifestations of DDoS attacks. Intrusion detection systems can detect anomalous traffic and take timely countermeasures.

Attack response plan:

Preparing a response plan is an effective way to prevent DDoS. This usually includes suspending the attacked service, changing the network configuration and reporting the incident to authorities if necessary.
