"Computer security, cyber security, digital security or information technology security (IT security) is the protection of computer systems and networks from attacks by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide."
The study of protecting computer systems and networks from unauthorized access, data theft, and other security breaches.
Computer Security Basics: Provides an introduction to the various aspects of computer security including the different types of threats and the strategies used to protect against them.
Network Security: Covers the techniques used to secure networks, including firewalls, intrusion detection, and prevention systems, and virtual private networks.
Cryptographic Principles: Provides an overview of cryptography concepts, including encryption, decryption, digital signatures, hashing, and public key infrastructure (PKI).
Cryptography Algorithms: A deep dive into the popular symmetric and asymmetric algorithms such as AES, DES, RSA, and ECC, and their usage in securing data.
Security Protocols: An explanation of common cryptographic protocols such as TLS, SSH, and IPSec used to establish secure communication channels over the network.
Access Control and Identity Management: Discusses principles and practices of identity authentication and access management, including two-factor authentication, biometrics, and access control policies.
Security Testing and Vulnerability Assessment: Explains the different approaches used in security testing, including penetration testing, vulnerability assessments, and ethical hacking.
