What is Zero Trust Network Access? ZTNA Explained
ZTNA is a security solution that ensures an organization’s network, data and applications are protected from outside threats. It provides a monitoring system which detects any attempted intrusion on the network, along with a line-of-defense to block all traffic coming from unknown or untrusted sources. ZTNA is designed to protect your business from unauthorized access by leveraging its IT infrastructure and defensive technologies.
Zero Trust Network Access provides a security solution that will help protect your company’s network infrastructure by providing defensive technologies such as malware protection and spam filtering.
It also offers an advanced monitoring system which detects any attempted intrusion on the network along with a line-of-defense to block all traffic coming from unknown or untrusted sources. This way, your business will be safe even if the employees are using public Wi-Fi hotspots for remote work or checking personal email accounts.
Zero Trust Network Access (ZTNA)
ZTNA is an IT security solution which provides your organization with an additional line of defense, designed to protect your business from unauthorized access by leveraging your company’s network infrastructure.
Zero Trust Network Access (ZTNA) is a security solution for complex networks that requires an incoming connection be authenticated, authorized and inspected before gaining access to the trusted zone of the internal network. This approach limits potential threats by ensuring that users and computers can only access applications and other resources that should be available to them.
Secure Incoming Traffic
ZTNA is a network security model in which all incoming traffic to an organization’s internal network is assumed to be untrusted until proven otherwise, with the next logical step being a completely locked down system requiring explicit authorization for every connection.
Isolated Zones
This approach requires a number of components including an authentication, authorization and access control system which can verify the security posture of a connection. The model is designed to seal off network segments, whether they be portions of the internal network or individual cloud applications. It creates an isolated zone within the trusted zone to which only approved endpoints are allowed access.
Using Internal Network for Protection
To put it simply, ZTNA is a security solution that ensures all systems and data are protected from outside threats by creating an internal network which uses cloud infrastructure to inspect connection intent. It provides advanced malware protection and spam filtering.
ZTNA creates an isolated zone within the trusted zone to which only approved endpoints are allowed access. All endpoints that are not allowed into the trusted zone are routed to a separate or “untrusted” or “external” network, like an Internet gateway.
Security Against Unauthorized Access
Most information technology (IT) security professionals recognize that traditional approaches to endpoint security can be breached by advanced persistent threats.
It is challenging for traditional approaches to secure the endpoint, particularly when employees can bring their own devices (BYOD) to work. ZTNA is designed to protect your business from unauthorized access by leveraging its IT infrastructure and defensive technologies.
Conclusion
ZTNA is a great security solution that ensures an organization’s network, data and applications are protected from outside threats. It provides a monitoring system which detects any attempted intrusion on the network, along with a line-of-defense to block all traffic coming from unknown or untrusted sources.
