This topic separates three ideas that are often confused: keeping data secure, keeping it private, and keeping it accurate. You will study threats including malware, hacking, phishing, pharming and accidental damage, and the measures used against them — firewalls, authentication, access rights, encryption, biometrics, digital signatures and backup procedures. The final part covers data integrity through validation and verification, including the specific checks used and what each one can and cannot catch.
