Enabling zero trust security in your environment

Zero Trust is a principle that is coming to all business, why? because helps secure corporate resources by eliminating unknown and unmanaged devices and limiting lateral movement.

So… when we are trying to implement a Zero Trust model, we will touching all components—user identity, device, network, and applications— to be validated and more important to be trustworthy.

But, what about the main components to be aware of? Let’s keep a further detail to that list:

  1. Identity – Identity is the best starting point for Zero Trust. I’am a big fan of AAD identity, and Conditional Access, PIM is a great way to start
  2. Implement conditional access controls – we can stop compromise identity credentials from accessing to corporate resources and more important, avoid a move laterally in the network.
  3. Strengthen credentials – Weak passwords undermine the security of your identity system, so take aware of that and use MFA
  4. Integrate intelligence and behavior analytics – Having tools to automate tasks and detect some behaviours, are great! Keep an eye to ATP, WDATP, MCAS…
  5. Reduce your attack surface – nothing to explain here 🙂
  6. Increase security awareness – Use a Security Information and Event Management (SIEM) system to aggregate and correlate the data to better detect suspicious activities and patterns.
  7. Enable end-user self-help – users are the core of the business, we cannot enable security tools without thinking in them
  8. Don’t overpromise – Zero Trust is not a single ‘big bang’ initiative, so keep in that mind
  9. Show value along the way – One of the most effective ways to build long-term support for a Zero Trust initiative is to demonstrate incremental value with each investment.

As you can see here A Zero Trust model is not easy to achieve, but it’s a key element of any long-term modernization objective for the digital enterprise. If you want to assess your system yourself, keep an eye to the following tool: Take the Zero Trust Assessment (microsoft.com)
