A CISCO-based course on cybersecutiry essentials
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.
Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative. -

Welcome to The Art of Ensuring Integrity
Integrity ensures that data remains unchanged and trustworthy by anyone or anything over its entire life cycle. Data integrity is a critical component to the design, implementation and usage of any system that stores, processes, or transmits data. This chapter begins by discussing the types of data integrity controls used such as hashing algorithms, salting, and keyed-hash message authentication code (HMAC). The use of digital signatures and certificates incorporates the data integrity controls to provide users a way of verifying the authenticity of messages and documents. The chapter concludes with a discussion of database integrity enforcement. Having a well-controlled and well-defined data integrity system increases the stability, performance, and maintainability of a database system.
