A zero trust strategy ensures that you only offer the minimum power required by confirming the identity of the person requesting the access, the context of the request, and the level of risk associated with the access environment. By putting the Zero Trust Model into practice, you can decrease attack surface and cybersecurity risk while improving audit and compliance monitoring.
The enactment of the Zero Trust is based upon these six principles.
1. Don’t rely upon; always check – Identity encompasses not only individuals but also tasks, services, software, and hardware. Utilizing business directory identities, removing local accounts, and reducing the number of accounts and passwords are necessary for proper identity verification.
- For this reason, several businesses such as Foxpass have invested in identity management programs like Auth0, Active Directory, or Okta. If someone wants to access it, you have to know who they are.
- The most crucial component has directory IDs that are HR-vetted and immediately disabled after an employee leaves the organization.
- Multi-factor authentication (MFA) should also be used everywhere whenever there is a new request, during login, password checkout, privilege escalation, or at any moment. If someone wants to access it, you have to know who they are.
2. Provide context for requests – You must comprehend the objective behind every request before you can approve it. To accomplish this, you must understand the context of the access request, review it, and decide whether to grant it if the context justifies it.
- People should only have the privileges necessary to do a task and only for the duration required to complete the activity.
3. Protect your administrative setting – A clean source should be used to gain access to restricted resources. This entails prohibiting direct access from user workstations with Internet and email access, which are prone to malware infection.
4. Allocate the Least Privilege – There are six different ways to approach the least privilege principle.
- Group-based access control: It is nearly impossible to manage individual user access for hundreds or thousands of employees while upholding the principle of least privilege. Tools for identity access management (IAM) are therefore available. IAM technologies manage requests based on groups rather than individuals and provide users access based on groups or job responsibilities.
- Access control based on working hours: If an employee has a regular schedule, you can limit access based on those hours. For instance, an employee should not be permitted to use their keycard at 4:00 am on Sunday if they only work from 8:00 am to 5:00 pm Monday through Friday.
- Location-based access control: For crucial systems, you might only want employees of your office building to have access to them.
- Machine-based access control: Similar to location-based access control, you could only want particular computers to access essential systems.
- Management of access for one-time use: Use a password safe where privileged accounts’ single-use passwords are checked out until the task is finished and checked back in.
- Managing access just-in-time: When necessary, elevate privileges for a particular program, then after the task is over, restore to an ordinary account.
5. Review every aspect – Keep a track of everything that takes place during a privileged session; this is helpful for computer forensics and also makes it possible to assign activities to specific users. For example, you may decide to save a video recording of the session for systems containing sensitive data so that it may be viewed later or used as proof.
6. Use adaptive controls – Controls with zero trust model must be risk-context-adaptive. For example, even if the request originates from a verified user, you could decide to seek additional verification if the request is coming from a dangerous place.
- Adaptive controls should alert you to potentially dangerous conduct in real-time and enable you to take immediate action by interrupting sessions.
