Is it required to memorize the key length for cipher algorithms (at least the ones from the official book) and hash value lengths? Is anyone doing this?

I was studying the cipher modes today. Here is what I learnt; CBC-MAC is mainly used for integrity, authenticity; CCM,GCM provides authenticity, integrity and confidentiality; CTR, CFB,OFB, CBC,ECB provides confidentiality.

A huge congratulations to @Will Bad for passing his CISSP!! 🙌 Hear some of his experience in the first few minutes of this session followed by another fantastic presentation by @Josh Botz on Identity & Access Management Protocols crucial for exam success and real-world application. This session covers the ins and outs of SSO, Federated Identity, OAuth, Kerberos, and more, with a focus on scalability and security in modern web applications.

Welcome to the group! Please share what you hope to gain from being here, and for fun tell us the best piece of advice you've ever received.

Hi, I joined this study group today. Glad to be part of this group. I have been working as an IT Architect, currently taking a break from work. I want to enter back into work field with a new role using the help of CISSP. Aiming to take this cert around Dec, 2024. Have been preparing for this cert for the past one month. Looking forward to learn with you all.
