What is zero trust?
Zero trust is a security framework that assumes that no user or device can be trusted by default, regardless of its location or network. Under this framework, all access to resources must be verified, regardless of whether it is coming from inside or outside the organization's network.
Zero trust is based on the following principles:
- Never trust, always verify: No user or device should be trusted by default. All access to resources must be verified before it is granted.
- Least privilege: Users should only be given access to the resources they need to do their job. This helps to minimize the damage that can be done if a user's account is compromised.
- Microsegmentation: The network should be segmented into small, isolated zones. This helps to contain a breach if it does occur.
- Continuous monitoring: The network should be continuously monitored for suspicious activity. This helps to identify and respond to threats quickly.
Why is zero trust a popular security framework?
Zero trust is a relatively new security framework, but it is quickly gaining popularity. It’s a more secure approach to cybersecurity than traditional perimeter-based security models, which rely on the assumption that the network perimeter can be effectively secured. Remote work, cloud computing, and other advances have rendered this approach ineffective. Zero trust provides a more secure alternative by assuming that the network perimeter cannot be effectively secured and by focusing on verifying access to resources at all times.
What are the benefits of adopting zero trust?
There are a number of benefits to adopting a zero trust security framework. These benefits include:
- Increased security: Zero trust helps protect organizations from a wider range of threats, including insider threats, data breaches, and ransomware attacks.
- Reduced costs: Zero trust can help organizations reduce the costs associated with security by eliminating the need for expensive perimeter security devices and solutions.
- Improved agility: Zero trust can help organizations be more agile and responsive to change by providing a more flexible and scalable security framework.
