With the increase in remote and hybrid work environments setting off a 238% jump in cyberthreats, more businesses than ever are looking for ways to tighten up security while still allowing employees to connect, collaborate, and be productive. That is why many are now adopting a zero-trust security framework, whether they have an on-premise, cloud, or hybrid network.
A zero-trust security plan ensures that every user that accesses your network, system, or an application resident on these system is verified and authenticated before they are given access to tools, technology, or data. In essence, no users — employees, contractors, subconsultants, or third-party partners — are allowed access without meeting the requirements for validation. These strict policies are necessary to ensure that infrastructure and information stay secure, especially as remote work increases and new cyberthreats evolve that can cause serious harm to your business.
The zero trust architecture is outlined by the National Institute of Standards and Technology (NIST) in SP 800-207, and is meant to include remote users, users of Bring-Your-Own-Device (BYOD), and even assets based in the cloud.
How to Implement Zero Trust Security
Implementing a zero-trust security plan requires an investment in time as well as financial resources. Even companies that have an in-house IT staff often do not have the knowledge pool available to tackle evolving threats and new technologies. For this reason, many businesses choose to work with a third-party partner that provides comprehensive Managed IT Services that emphasize cyber security. In a nutshell, here a several things you must consider when designing a zero-trust architecture for your business:
Determine the Right Access Management Level
Reducing instances of compromised identity is the key to any zero-trust network. You will need a single source, trusted authentication for all users. Multi-factor authentication should be enabled for all sensitive accounts, and potentially every account. Logging and auditing should be enabled for clear visibility into user actions and authentications. Finally, there must be a single source that managed every user’s role assignment including on- and off-boarding and role changes.
Inventory Managed and Unmanaged Devices
Now that you have authenticated users, you must pair them with the correct device. An authenticated users receiving access through an unmanaged, personal device that has no security measures can promote vulnerabilities. For best results, you should have a complete inventory that identifies each managed and unmanaged device used with your network and can define scenarios for access that are based on device type. Having an endpoint security solution can assist with this task.
Determine Access Scenarios
Look at access scenarios based on destination and source. For example, access can be achieved through cloud-based data centers, services that host sensitive information, or infrastructure-as-a-service (IaaS) that may use multiple clouds or data centers. Sources can include both on-premise or remote workstations; third-party contractors; business partners; consultants who may need last-minute privileged access to fix a critical issue.
Create a Zero Trust Solution
Decide which solution matches your business needs and challenges, such as:
- A platform that is cloud-based versus one that is on-site
- A platform that integrates with other solutions
- A platform that offers governance versus access to user actions
- A platform that provides access to corporate resources versus one that also governs the user activities while using the resource.
Once you’ve selected the right solution, you can begin to convert your access policies to zero-trust policies to fully isolate and protect your work environment.
