What is DDOS Deflate?

DDOS Deflate is a lightweight bash script that can be used to protect a server from Distributed Denial of Service (DDOS) attacks. It works by monitoring incoming network connections and identifying and blocking IP addresses that are sending a large number of requests.

One of the key benefits of DDOS Deflate is its simplicity. The script is easy to install and configure, and it requires minimal resources to run. Additionally, DDOS Deflate is compatible with most Linux distributions, making it a versatile option for protecting servers.

Another benefit of DDOS Deflate is its effectiveness in identifying and blocking malicious traffic. The script uses advanced algorithms to detect and block IP addresses that are sending a large number of requests, which can help to mitigate the impact of a DDOS attack.

One limitation of DDOS Deflate is that it is not a complete solution for protecting servers from DDOS attacks. It can only block incoming traffic from IP addresses that are identified as malicious, but it cannot protect against other types of attacks such as SYN flood attacks or UDP floods. Additionally, DDOS Deflate is not actively maintained anymore, so it may not be suitable for newer systems.

Overall, DDOS Deflate is a useful tool for protecting servers from DDOS attacks. Its simplicity and effectiveness make it a great option for small business owners or individuals who need to protect their servers from malicious traffic. However, it is important to note that it is not a complete solution and it is not actively maintained anymore, so it may not be suitable for newer systems.
