Essential Guide to Install DDoS Deflate on CentOS

In today's digital landscape, businesses, especially those in the IT Services & Computer Repair and Internet Service Providers sectors, are increasingly reliant on web presence. With this reliance comes significant risks associated with cyber threats, such as DDoS (Distributed Denial of Service) attacks. In this detailed guide, we will delve into how to install DDoS Deflate on CentOS, ensuring your server remains robust and secure against these malicious attacks.

Understanding DDoS Attacks

Before we jump into the installation process, it’s crucial to understand exactly what a DDoS attack entails. A DDoS attack occurs when multiple compromised systems are used to flood a target system with traffic, overwhelming it and making it inaccessible to genuine users. The consequences can be devastating for any business:

• Loss of Revenue: Downtime can lead to lost sales, especially for e-commerce platforms.
• Damaged Reputation: Frequent downtime can make clients and customers lose trust in your services.
• Increased Recovery Costs: Responding to and recovering from an attack can be costly, both financially and in terms of resources.

What is DDoS Deflate?

DDoS Deflate is a lightweight Bash script designed to mitigate DDoS attacks. It manages incoming traffic by blocking IP addresses that exceed a predetermined number of connections, thus preventing the server from being overwhelmed. This tool is essential for protecting your server, especially if you host websites that attract substantial traffic.
