Currently, network attacks are frequent and diverse in types, with varying scales of attacks. Faced with increasingly fierce cyber attacks, cyber attacks have always been a topic of concern for webmasters. How to maintain network security without affecting the use of cloud servers and ensuring website security has become a top priority for webmasters in their daily work. Jtti is going to share with you today about how VPS in the United States can defend against DDOS attacks!

Method 1: Use a firewall

Firewalls are a common way to prevent attacks, and deploying firewalls can effectively detect attack traffic and intercept abnormal traffic in a timely manner. Firewall technology can detect information such as source IP address, target IP address, port number, protocol type, and traffic size, effectively defending against network attacks.

Method 2: Network intrusion detection system

Use a network intrusion detection system to analyze network traffic information entering the server, effectively detect DDOS attacks, and take timely defense measures. The network intrusion testing system is mainly used to collect network data, and then analyze the collected network data to immediately intercept abnormal traffic. The network intrusion detection system can also analyze network data, track the attacker's IP address, and efficiently defend against DDOS attacks.

Method 3: Flow cleaning technology

Traffic cleaning technology utilizes the detection and cleaning of network traffic to resist network attacks. Traffic cleaning technology can effectively detect abnormal attack traffic and intercept it in a timely manner by detecting network traffic. This way, the website will not be attacked, and traffic cleaning technology can also be used when network traffic filtering is needed. Retaining useful traffic can improve network efficiency.

Method 4: Utilizing Load Balancing Technology

Load balancing technology can distribute network traffic to multiple hosts, effectively defending against DDOS attacks. By distributing network traffic to multiple servers, load balancing technology can prevent attackers from finding the real server, thereby protecting the real server from attacks.

Method 5: Multilayer protection mechanism

Multi layer protection mechanism is a common way to prevent network attacks, mainly including network layer and application layer. In the network layer, abnormal traffic is detected by detecting information such as IP address, target IP address, port number, protocol type, and traffic size, and then intercepted in a timely manner. The application layer detects and intercepts attacks through a web application firewall, which can effectively defend against DDOS attacks.

In summary, it is a common way for VPS to effectively defend against DDOS attacks. In addition, network encryption technology, traffic isolation technology, etc. can also be used to effectively defend against DDOS attacks.
