This yr has not been quiet for the cybersecurity discipline. We’ve seen record-breaking knowledge breaches, large ransomware payouts, and illuminating research concerning the affect of the more and more complicated and ever-evolving menace panorama.
As we strategy the brand new yr, TechRepublic revisits the most important cybersecurity tales of 2024.
