Focusing on defending the perimeter has been akin to wearing a Hazmat suit in a hostile environment: Any small perforation, and you were doomed to unexpected consequences at the hands of hackers who had the time and intellect to play games with your critical assets.
Not only are perimeters fragile and the gap in available talent huge, but most IT teams are often so stretched for resources that they can’t keep up with the updates necessary to protect against the myriad attacks that can penetrate a company’s external defenses. WannaCry was just an example of that.
Over the years, computing speed has grown exponentially –multiplying more than 3,000x since 1991 – to the point where even a $5 Raspberry Pi can now run deep learning algorithms. So it’s not a surprise that, in recent years, focus has shifted to using AI cybersecurity to complement traditional defenses in many ways and neutralize stealthy, unknown threats that may have already breached the perimeter before any irreparable damage to network or data is done.
In AI cybersecurity programs, which are now being embedded in companies’ networks, endpoints and data are evolving into immune systems that allow internal defenses to shorten the dwell-time and pre-empt the devastation that can follow a breach.
While there is no need to abandon the perimeter, today’s smart CISOs are squarely focused on increasing their AI-driven pre-emption capabilities and boosting their own auto-immune systems. Artificial intelligence in cybersecurity is by no means perfect yet, but cybercriminals are already using automation and machine learning 24x7x365. In the never-ending cat-and-mouse game, AI is slated to continue gaining ground to build predictive capabilities and strengthen defenses for the foreseeable future.
