Want to protect what you’ve built? Then you’ll need to work differently, according to Melanie Rieback.

This CEO of Radically Open Security, one of the world’s first cybersecurity consultancy nonprofits, says that while hacks are inevitable, it’s up to companies to navigate that risk — not try to eliminate it.

In a talk at Oslo Innovation Week, she shared three principles that can help companies find the solutions that work for them and their industries. These ideas, she says, will shape the mindset anyone will need to better approach modern cybersecurity.

1.Work with your rivals.

She points out that banks have recognized the need to create an open dialogue with their rivals, sharing things like firewall rules – and other industries must think the same way. The way we have approached competitors in the past has become less relevant, she says.

2. Rethink your secrets.

“The more you are open, the more you present to the world, the more intellectual property you keep and the less you give away, the less you have to fear and the smaller your attack surface becomes,” she says.

3. Stop trying to ‘buy’ peace of mind.

“Ultimately, every proprietary solution makes you dependent on some vendor to essentially customize [a solution] for you and all its improvements,” she says.

Instead, Riebeck stresses the importance of open-source solutions and industry initiatives — including some that already exist — which share “indicators of compromise” like subject lines or fingerprints of files that might be malicious.

“If you can then take that threat intelligence, and share it with one another, then everyone can detect it and monitor for it. Or block it.” Says Riebeck. “Everyone becomes better by working together.”
