How to defend against DDoS attacks

DDoS attacks are currently one of the most effective forms of malicious network attacks, which are more targeted at DNS. In this quarter, Trend Micro discovered a wave of DDoS reflection attacks targeting the Communication Protocol Vulnerability. These attacks will use the intruded network to send a large number of Reply packets and error messages to the attack target.

By default, servers with low security will become the targets of DDoS reflection attacks. Hackers can use these vulnerabilities to attack the selected targets more easily.

In fact, this attack as early as 13 years ago has had a solution, that is, BCP-38. So how can we prevent DDoS attacks? Below, Trend Micro provides a summary scheme:

Use firewalls to cope with large-scale attacks

In the face of large-scale DDoS attacks, enterprises should first use the data center firewall to defend against such attacks. In this case, you must select an anti-DDoS data center.

Uses specialized DDOS defense devices to identify, isolate, and fix attacks.

To effectively defend against multi-vector attacks, we must make full use of the dedicated defense devices deployed by the company. firewalls and intrusion defense systems are crucial in mitigating DDoS attacks, the DDOS security defense device builds an additional protective layer to identify and intercept dos activities in real time using dedicated technologies.

Adjust the firewall to handle a large number of Connection Rates

In the case of DDoS attacks, the firewall will be a key network device. Administrators should adjust their firewall settings to identify and handle large volumes of depletion and application layer attacks. In addition, depending on the performance of the firewall, some protection functions can be activated to prevent

DDoS attack packets improve firewall performance during the attack Process

At present, the website alone cannot achieve results in response to DDoS attacks. It requires powerful equipment room hardware and professional technical support. Therefore, it is particularly important to choose a reliable anti-DDOS service.

It is hoped that one day these website malicious attacks will completely disappear and the online world will remain clean.
