DoS and DDoS attacks
A Denial of Service (DoS) attack is a malicious attempt to disrupt the normal functioning of a targeted server, service, or network by overwhelming it with a flood of internet traffic. This traffic flood is typically generated from a single source. These attacks can inflict significant damages by rendering targeted services unavailable, causing financial losses, disrupting business operations, and potentially leading to data breaches.
A Distributed Denial of Service (DDoS) attack is an extension of a DoS attack, where the malicious traffic comes from multiple compromised computers, forming a botnet. This coordinated effort to overwhelm a target makes DDoS attacks more potent than traditional DoS attacks.
How to prevent DoS and DDoS attacks?
-
Network Monitoring:
- Regularly monitor network traffic for unusual patterns;
- Detect and analyze sudden spikes in traffic that may indicate a DoS or DDoS attack.
-
Load Balancers:
- Distribute incoming traffic across multiple servers using load balancers;
- Helps prevent overwhelming a single server and ensures service availability.
-
Rate Limiting:
- Implement rate-limiting mechanisms to restrict the number of requests a user or IP address can make within a specified time frame;
- Reduces the impact of flooding attacks.
