Study Notes
Cryptographic Algorithms and Data Security
- Cryptographic algorithms like AES (Advanced Encryption Standard) are used to conceal small blocks of data, including encryption keys and hash function values.
Lecture on Information Technology
- The main aim of the lecture on Information Technology is to provide an understanding of how IT supports business processes and impacts strategic goals.
Data Confidentiality
- Data confidentiality ensures that sensitive information is accessible only to authorized users, protecting it from unauthorized access and disclosure.
CIA Triad
- The CIA Triad stands for Confidentiality, Integrity, and Availability, and is fundamental to computer security objectives, serving as a guiding framework for developing security policies.
Challenges of Computer Security
- A significant challenge associated with computer security is the constant evolution of threats, which necessitates continuous updates and adaptations to security measures.
OSI Security Architecture
- The OSI Security Architecture classifies a security attack as any action that compromises the integrity, confidentiality, or availability of information.
Purpose of Authentication Protocols
- Authentication protocols serve to verify the identity of users and devices, ensuring that only legitimate entities gain access to restricted systems and data.
Data Integrity
- Data integrity assures that information remains accurate, consistent, and trustworthy over its entire lifecycle, safeguarding against unauthorized alterations.
Low Impact Security Breaches
- A breach of security with low levels of impact is characterized by limited consequences, such as exposure of non-sensitive data or temporary access disruptions.
