    Course Rationale:

    Information security — or infosec — is the protection of information by people and organizations in order to keep information safe for themselves, their company, and their clients. Every organization needs protection against cyber-attacks and security threats. Cybercrime and malware are constant threats to anyone with an Internet presence, and data breaches are time-consuming and expensive. The goal of IT security is to protect these assets, devices and services from being disrupted, stolen or exploited by unauthorized users, otherwise known as threat actors.
