The Evolution of Cybersecurity: A Journey Through Time
In today’s hyper-connected world, cybersecurity is more important than ever. But how did we get here? The history of cybersecurity is a fascinating tale of innovation, challenges, and the ongoing battle between attackers and defenders.

Security wasn’t a concern because these machines were isolated and rarely connected to anything else. Encryption, however, was already being used by governments during World War II, laying the groundwork for secure communication in the digital age. Fast forward to the 1960s, when time-sharing systems allowed multiple users to access a single computer simultaneously. This marked the first real need for security measures—after all, if multiple people c...
