With real-time backups and good monitoring, you stay ahead of attackers. Keeping physical security strong and using strong encryption helps too13. As threats grow, keep improving your security to stay ahead14.
Rate Limiting: A First Line of Defense
Rate limiting is key to protecting your website from DDoS attacks. It limits the number of requests a server can handle from one user in a set time. This way, you stop bad traffic while letting good users in.
Setting up these limits right keeps your site running smoothly. It blocks threats while letting real users use your site.
How Rate Limiting Works
Rate limiting checks how often users from the same IP address ask for things. For example, it might stop a user from making more than 100 requests in a minute15. This stops DDoS attacks by limiting how much each user can do16.
There are many ways to do rate limiting:
- • User-Based Rate Limiting: Limits access based on specific user identifiers like IP addresses17.
- • Geographic Rate Limiting: Restricts requests from specific locations17.
- • Time-Based Rate Limiting: Uses timestamps to regulate the request flow17.
- • Token Bucket and Leaky Bucket Algorithms: Manage traffic flow efficiently to prevent overload17.
- • Fixed and Sliding Window Log Algorithms: Allow flexible control over request management17.
Setting Up Effective Limits
Start by checking your network and apps. This helps you create a plan that fits your needs15. Pick an algorithm that works for you15.
Keep an eye on your limits and change them as needed. You might block good users by mistake or deal with sudden spikes in traffic17. Working with Web Application Firewalls (WAFs) and network firewalls helps a lot16.
Using the right rate limiting keeps your site safe and running well. It fights off DDoS attacks effectively171615.
