2018 was an interesting year for Insider Threat. While most CISOs were already painfully aware of the risks posed by insiders – both malicious and inadvertent – the public has a growing understanding of how business can suffer because of employee misbehavior. In a well-publicized case filed in the Northern District of New York, an all-too-common scenario serves as the perfect illustration: an engineer who worked for a large U.S. company was accused of stealing trade secrets (see, for example, coverage from the WSJ. While this case is still making its way through the court systems, it appears that good sleuthing from defenders detected the data leak, but not before significant damage potentially occurred.Part of the challenge with insider threat mitigation stems from the complex relationship employees have with their employers. Thus, while there are technical steps that companies can deploy, optics, trust, and privacy can provide significant drag to adoption. To this end, I’d like to examine these issues head on, and provide some guidance on how to chart a course through this minefield. If done correctly, a significant win/win exists for the defenders and those they are charged with protecting.Let’s start with the
elephant in the room: trust. I’ve argued many times that for maintaining
security, the ability to leverage trust is a superpower. Moving away from
simplistic models of “good” and “bad” allows companies to take a more nuanced
and ultimately more effective approach to securing networks. While creating
concepts of digital trust for machine-to-machine interactions is relatively
straightforward, understanding the complex web of trust that exists between
humans is much more complex – and rapidly changing (for an approachable
introduction to this area, I recommend Rachel Botsman’s book “Who Can you
Trust?”). As Botsman notes, some of the most powerful technology companies in
the world (Uber, AirBnB, and Alibaba) all base their business in no small part
on brokering trust between third parties. Similarly, the excitement around
Blockchain technology is underpinned not merely by speculation on the price of
cryptocurrencies, but ultimately by the new markets decentralized trust models
can enable.
Not only is trust a cybersecurity superpower, it’s also a driver of growth. In a recent Accenture whitepaper (downloadable ), researchers note that companies who can engender employee trust reap a 12.5% bonus on their growth versus those who cannot – quite a premium.If trust is key, then
the route forward lies not in technical mitigations (we have plenty of good
technology for monitoring user interactions, for example), but in a
multi-disciplinary approach that helps defenders build trust and not break it.
That turns us nicely to our two related concepts: optics and privacy.When we talk about the
optics of Insider Threat programs, the most common mistake is for employees to
feel like they are being watched or are inherently distrusted. Neither of these
outcomes needs to be the case, but great care must be taken in how
human-centric solutions are rolled out. Research shows that employees can be
your greatest asset here, but it all depends upon a transparent discussion
about the goals of the program and the risks it intends to mitigate. Done
properly, the optics can be handled, but only by facing difficult or sensitive
issues head on. Transparency is key.The concept of
transparency is also important when dealing with another significant drag on
adoption: end-user privacy. While we want transparency about what is collected
and how it is used, we don’t want
transparency regarding the actual raw data: nobody wants to live in a
modern-day panopticon! Thus, governance and technology need to work hand in
hand to maintain, or better yet enhance, the privacy of employees. Neither side
can do this alone; as a CISO your new best friends are the General Counsel,
DPO, and CHRO. If you’re not having regular meetings with these folks, well,
you should be. We’ve looked at some
ways we break trust, but what of building it? That, sadly, is much harder.
Quoting one of the modern-day philosophers of our time, Lady Gaga, “Trust is
like a mirror, you can fix it if it’s broken, but you can still see the
crack…”. Thus, the first step is not to break the fragile trust we actually
have in place. Alas, the second step of building trust is much harder, and
extends well beyond the remit of the CISO: no matter how much the security team
embraces best practices, for example, if the employees don’t trust the
company’s senior management, there’s no win in sight. No, the approach here
needs to be much broader and involves significant effort. There’s a whole
fascinating discussion we could have about how you even measure
employee/employer trust, but we will have to leave that for another day.Better yet, cybersecurity
isn’t the only winner from such an undertaking. Unfortunately, the CISO and her
team can only influence these aspects
of organizational climate, not control them. That larger project once again
underscores how the CISO’s sphere of influence must not just be in the
technical world, but across the entire enterprise. While holism is always nice
in principle, in this case it is a necessity. That means that to be successful,
the CISO must build both strong and weak ties across the entire organization:
that’s sometimes a stretch for battle-hardened technical experts, but a stretch
worth taking on, as the rewards are immense. Dr. Richard Ford

There are many ways to do DevSecOps, and each organization — each security team, even — uses a different approach. Questions such as how many environments you have and the frequency of deployment of those environments are important in understanding how to integrate a security scanner into your DevSecOps machinery. The ultimate goal is speed […]
It’s Cybersecurity Awareness Month, but security awareness is about much more than just dedicating a month to a few activities. Security awareness is a journey, requiring motivation along the way. And culture. Especially culture.That’s the point Proofpoint Cybersecurity Evangelist Brian Reed drove home in a recent appearance on Business Security Weekly.“If your security awareness program […]
