Zero trust is a security concept that involves authenticating all users even those who are within the enterprise network of the organization. Security posture and configuration will be validated continuously before granting or keeping access to data and application. This method uses advanced technologies like next generation endpoint security technology, identity and access management, as well as multifactor authentication to check the identity of the user and to maintain the system security.
Zero trust is an important departure from conventional network security, which adhered to the trust but verify approach. The conventional method trusted endpoints and users automatically within the perimeters of the company, placing the business at risk from malicious internal factors and letting unauthorized users far reaching access when inside.
But, zero trust network could only be successful if the companies can always check and validate that a user and their device has the appropriate attributes and privileges. One time validation will not be enough since user attributes and threats are always changing.
Consequently, companies need to make sure that every access request is vetted continuously before permitting the connection to any cloud asset or enterprise. That is why the implementation of zero trust rules depend heavily on real time visibility into user attributes including user identity, firmware versions, endpoint hardware type, patch levels, security incident detections, user logins, applications installed, as well as vulnerabilities.
Why is zero trust security important?
Zero trust is among the most effective methods for companies to control access to their data, applications, and networks. It mixes a wide array of preventative measures including end point security, microsegmentation, identity verification, as well as least privilege controls to prevent possible attackers and restrict their access in case there’s a breach.
This additional layer of network security is important as companies boost their number of endpoints within the network and then expand their infrastructure to include cloud based servers and applications. These trends make it a lot more difficult to create, monitor, as well as maintain a well secured perimeter. Aside from that, a borderless cybersecurity strategy is crucial for those companies that have a global workforce and provide employees the ability for them to work remotely.
What are the principles of a zero trust model?
The zero trust model follows certain principles. It re-examines all of the default access controls and uses different preventative methods. It allows real time monitoring to determine malicious activity as fast as possible and align to the wider security method.
How to achieve zero trust network security?
Even though the needs of each company is unique, there are a few ways to develop and implement a zero trust model. These includes evaluating your organization, creating a directory of all your assets and then map the flow of transaction. You should create different preventative measures and make sure that you monitor your network security continuously. Find out where suspicious activities take place and check all the surrounding activity.
