Dark Reading editors reflect on twenty years of cybersecurity evolution, highlighting a persistent paradox in the industry: while organizations rush to adopt cutting-edge technologies like AI and cloud computing, they continue to struggle with basic security fundamentals like strong authentication, timely patching, and network segmentation. The pandemic emerged as a major inflection point that accelerated the shift from controlled on-premise networks to cloud-based infrastructure, dramatically expanding the attack surface with remote work, IoT devices, APIs, and non-human identities. Looking ahead, the editors warn that concepts like least privilege and asset inventory remain underutilized despite being discussed for two decades, and are now exponentially more complex with AI agents and ephemeral systems in the mix.
