Historically cybersecurity was typically a reactive, passive activity. You waited until something happened and then a chain of activities kicked off—which often included wading through high volumes of alert data to identify the needle in the haystack.
Those traditional defensive techniques, inspired by and often compared to measures taken in the physical world, weren’t nearly enough to deal with the threat. Attackers evolved while defenders stagnated, leaving themselves vulnerable. While signature-based antivirus software, enterprise-grade firewalls, and operating system patches are pieces of the puzzle in the New Information Age, they aren’t nearly enough protection on their own.
Today we know that there’s no silver bullet. You need to be proactive, ready to act in the moment, and be prepared for anything.
