Best practices for preventing Denial of Service Attack in Django [closed]

Question

What are the best practices in Django to detect and prevent DoS attacks... Are there any ready to use apps or middleware available which prevents website access and scan through bots?

Answer 1

You might want to read the following 3 questions over on Security Stack Exchange.

A quick description of the problem:

• How does DoS/DDoS attack work?

Possible solutions and limitations of attempting mitigation in software:

• How can a software application defend against DoS/DDoS?

And a bit of discussion around commonly used anti-DDoS techniques at the perimeter, rather than the application:

• What techniques do advanced firewalls use to protect against DoS/DDoS?

It is really difficult to do at the application level - the earlier in the path you can drop the attack, the better.

Answer 2

I'd probably aim to deal with DoS at a higher level in the stack. If you're using Apache, take a look at mod_security. Or maybe a nice set of firewall rules.

Edit: Depending on your situation, you also might want to take a look at a caching server like Varnish. It's a lot harder to DoS you, if the vast majority of hits are served by the lightning quick Varnish before they even reach your regular web server.
