What is needed is a different approach, one that acknowledges that you’ll never have a border that is 100% secure. Instead of spending so much effort trying to seal the borders, how about taking steps to render what the successufl hackers do find completely useless to them? What I’m talking about is ensuring that all your sensitive data remain encrypted while at rest. If strong data encryption is applied to all sensitive data, and plaintext versions of it are never leaked to the outside, then, in the inevitability that a hacker manages to sneak through your enterprise’s ultimately porous borders, what they’ll find there is something they can’t read. And if they can’t read it, it is of no value to them and of no risk to you and me.
The challenge is simple to describe. Plainly, encryption is difficult. Ensuring that sensitive data are encrypted and never leave home without their encryption clothes on is by no means a trivial task. Modern encryption is rock-solid strong. AES, the Advanced Encryption Standard, is provably unbreakable in real time, at least with current computing power and attack strategies. If the data inside the porous walls is encrypted with AES and never exposed to people who shouldn’t see it, then the walls could be made of Swiss cheese, and no harm would be done. The product that provides ubiquitous encryption guarantees in a convenient and portable package is, in my estimation, the Holy Grail for computer security, because it will help reduce the unreasonable demands we currently place on our firewall people to keep the bad guys out. There are products that might deliver that promise; IONU (https://www.ionu.com/) i one leading contender. When such products gain widespread acceptance, I believe our global security posture is going to improve significantly, and attacks like this one will become just scary stories of the past.
