Guide to ELB Security Policies

What is ELB Security Policy?
ELB Security Policy refers to the predefined security configurations that ensure safe transfer of data during communication between the client and the load balancer. The ELB (Elastic Load Balancing) Security Polices are a combination of protocols and ciphers defining the SSL (Secure Sockets Layer) negotiations.

Why is it important?
The ELB Security Policices are crucial in ensuring a secure connection between the client and the load balancer. They safeguard against vulnerabilities and attacks by enforcing trusted protocols and ciphers, ensuring high-security standards protecting sensitive information.

How does it work?
The ELB Security Policy works by enforcing different SSL/TLS protocols and ciphers. During an SSL/TLS handshake, the load balancer selects the first protocol and cipher from the client's list that matches the list set in the security policy.

Exam Tips: Answering Questions on ELB Security Policies
Ensure you understand the relationship between the security policy, protocols, and ciphers, as well as how they collectively contribute to secure connections. Be aware of the most secure and recommended policies, and the effects of these policies on compatibility. Remember that ELB supports both predefined and custom security policies and have an idea of how to correctly configure both.

Exam questions may quiz you on your ability to match compatibility needs with the right level of security. The exam might also test your knowledge on migrating from less secure to more secure cipher suites, and the impacts this may have on a client's ability to connect to your load balancer.
