What is the impact of keep-alive on security?

Keep-alive connections can enhance performance but may also introduce security risks. For instance, they can make it easier for attackers to exploit vulnerabilities if a session remains open longer than necessary.

Can you explain how it makes it easier for attackers?

Certainly! If a keep-alive connection is maintained, it can allow an attacker more time to intercept data or exploit session hijacking vulnerabilities, especially if proper security measures like timeouts are not implemented.

What are some best practices to mitigate these risks?

Best practices include implementing session timeouts, using secure protocols like HTTPS, and regularly monitoring for unusual activity on persistent connections.

Are there any specific scenarios where keep-alive should be avoided?

Yes, keep-alive should be avoided in high-security environments or for sensitive transactions where the risk of session hijacking is a concern.
