With cyber attacks evolving in frequency and sophistication, organisations like yours need a cyber security approach that can keep these threats at bay. Adopting a zero-trust cyber security model - which is grounded in the idea that no device or user in your network should automatically be trusted without verification - can help address the cyber threats and security challenges facing your business today.
Steps to Adopting Zero Trust Security
STEP 1: Identify all users and non-person entities on the network
- Identify all your subjects and users. It could be humans and machines with access to your systems and networks.
- Pay special attention to users with special privileges.
- Apply logs and audit actions to verify and authenticate privileged access while monitoring access behavior patterns.
STEP 2: Identify your assets
- Identify and manage all the assets and devices that are directly or indirectly part of your organisation.
- The assets could include laptops, phones, Internet of Things (IoT) devices and digital artifacts, such as user accounts and applications.
- Additionally, monitor and configure changes to effectively evaluate access requests.
STEP 3: Identify key processes and evaluate risks associated with execution
- Identify and rank your business processes and data flow.
- Your business processes should clearly define how access requests are granted or denied.
- Consider starting with a low-risk business process as your zero trust candidate to avoid any negative impact on your organisation due to disruptions.
STEP 4: Formulate zero trust policies
- Identify and evaluate the risk associated with all your business processes and data flow.
- Improve security as part of zero trust integration.
- Establish a process to limit or restrict access during after-office hours or on weekends.
STEP 5: Identify candidate solutions
- Identify and evaluate a zero trust solution that best fits your business workflows and ecosystem.
- Check for components that could limit or restrict the use of personal devices at work or cross-agency collaborations.
- Determine if the solution works for your business process that exists entirely on-prem or in the cloud.
- Ensure the solution supports a wide range of use cases, such as web or email.
- Consider modeling an existing business process as a pilot program to test the zero trust architecture.
STEP 6: Initial deployment and monitoring
- After selecting a solution, consider initially running your new zero trust approach in reporting mode to ensure your policies are effective.
- Continue to monitor and adjust the network and assets.
- As you gain confidence in the process, you can start planning the next phase of zero trust deployment.
