Since COVID started I’ve been having a hard time keeping track of time. It feels like it’s been somewhere between 2 weeks and 2 years since this all began. After a bit of a hiatus I’m excited to start back on a regular cadence, sending out the ReThink Security Newsletter each month. Barring another global catastrophe, I’m happy to focus on bringing you security insights and interesting security related news.

Because we skipped last month there are more links than usual. I will organize them by priority and chronology, so you can see the most recent and most important news first.

Don’t forget to follow us on Twitter for our ongoing thoughts and realtime security news; our account wasn’t breached and we’ll never ask you for Bitcoin.

As predicted at the beginning of COVID we’re seeing many companies make the switch to working from home indefinitely. This is forcing a lot of companies to rethink their network security strategy. It is bringing forward one of my favorite strategies of zero trust network security. With this strategy you push security to the individual applications, devices, and systems to make decisions about authentication and authorization. Instead of relying on VLANs, VPNs, and network segmentation the systems themselves must make good decisions about the validity of the request.

Adopting a successful zero trust strategy is difficult and requires the use of many other systems including MDM, policies around BYOD, and Adaptive Authentication. These changes are not only technically difficult to roll out, but also have implications for employee adoption. Some employees may be resistant to install MDM on their personal devices. Security leaders will have to decide how to respond to this reluctance through policy. Adaptive Authentication can also be seen as invasive. Moving to Zero Trust is valuable, but there will be human complications in the rollout.

This has undermined many people’s confidence in the platform’s security. I understand security mistakes happen, so for me this is less about the issues that allowed this to happen and more about the unprecedented value that we put on the platform as a source of truth. Using social media as a realtime communication platform is one thing.Using it to disseminate policy, financial advice, or health and medical guidance is another thing. Twitter is doing more than Facebook to help give their users tools to identify false information, but this vulnerability in Twitter and Facebook’s most recent time in the spotlight highlights our reliance on these platforms for critical information. How we handle these kinds of issues will do nothing less than define us as a community. Mark Zuckerberg Is an Arbiter of Truth—Whether He Likes It or Not | WIRED
