Study Notes

Introduction To Cryptology

Cryptology is a branch of Applied Mathematics, encompassing both Cryptography and Cryptanalysis
Cryptography is the art and science of keeping messages secure, practiced by Cryptographers
Cryptanalysis is the art and science of recovering the plaintext from an encrypted message, practiced by Cryptanalysts

Computer Security

Computer Security is the protection of an automated information system to maintain the integrity, availability, and confidentiality (CIA Triad) of resources (including hardware, software, firmware, information/data, and telecommunications)
Confidentiality preserves authorized restrictions on information access and disclosure, including means for protecting personal privacy and proprietary information.
Integrity safeguards against improper information modification or destruction, ensuring information non-repudiation and authenticity.
Availability ensures timely and reliable access to and use of information.
These three aspects, Confidentiality (data and privacy), Integrity (data and system), and Availability, form the CIA Triad

More Computer Security Concepts

Authenticity: being genuine and verifiable, a trust in the validity of a transmission.
