Caesar cipher: A type of substitution cipher that is used to encode messages by shifting each letter in the original message by a fixed number of places in the alphabet. It is a simple and easily breakable cipher but is still sometimes used as a basic form of encryption for simple communication or as a starting point for more complex ciphers. For example, the message "Hello" with a shift of 3 would be encoded as "Khoor".

Capability Maturity Model Integration (CMMI): An enhancement of the original Capability Maturity Model (CMM), CMMI is a process and behavioral model that helps organizations streamline process improvement and encourage productive, efficient behaviors that decrease risks in software, product, and service development. The model provides a set of best practices that guide businesses through a continuum of improvements from an initial, ad hoc state of processes to a mature, disciplined state.

The Certified in Cybersecurity (CC) is key entry-level IT/Cybersecurity certification, the CC is a stepping stone for those new to IT Security and Cybersecurity. The CC exam is FREE right now: https://www.isc2.org/landing/1MCC Offered by ISC2, it caters to the increasing number of individuals pursuing cybersecurity careers without prior IT experience. Achieving the CC signifies a fundamental understanding of essential technical concepts and an ability to learn on the job, giving employers confidence in the holder's capabilities. There are currently over 769.000 open Cybersecurity jobs in the US. Worldwide there is a 4.8 million Cybersecurity workforce gap.  The average Cybersecurity Analyst in the US make over $99,000 a year. Get my Complete CC course with:

CCSP (Certified Cloud Security Professional): An advanced-level certification offered by ISC2 that validates expertise in cloud security architecture, design, operations, and service orchestration. CCSP certification is aimed at IT and information security leaders who aim to ensure the security of cloud environments.

Challenge Handshake Authentication Protocol (CHAP): A network authentication protocol where the server challenges a client to prove its identity. The server sends a unique challenge string, and the client responds with a value obtained by hashing the challenge with its password. If the values match, authentication is successful. CHAP provides more security than password-based authentication because the password is not sent over the network. It also periodically re-authenticates to protect against session hijacking or replay attacks.

Cipher Block Chaining (CBC) Mode: A mode of operation for block ciphers where each block of plaintext is XORed with the previous ciphertext block before being encrypted. This method ensures that identical plaintext blocks will encrypt to different ciphertext blocks, enhancing security. It uses an initialization vector (IV) for the first block to ensure randomness.
