This slide outlines the historical development of key cybersecurity defenses in a tabular workflow format. It covers firewalls (1980s) for traffic control, antivirus software (1980s-90s) for malware handling, IDS (1990s) for activity monitoring, and encryption/MFA (2000s+) for secure data and authentication.
