In an age where data breaches seem to be happening more and more often, companies are looking for new ways to secure their networks and keep their data safe. One of the newer security models being adopted by companies is zero trust network access. But what is zero trust network access, and how can it help your company protect its data? Stay tuned for our guide to zero trust network access definition!
Zero Trust Network Access Definition
ZTNA is a new access control paradigm that requires user and application authentication, authorization, and encryption of traffic. That is using modern cryptographic algorithms. It is based on a simple principle: If a user or an application cannot be authenticated, authorized, and encrypted, then they are blocked from accessing the network.
Zero Trust Network Access (ZTNA) is an approach to network security. It assumes that any user or application accessing the network must be treated as hostile actors. Thus, it should be assumed that any traffic to/from the user/application be treated as hostile traffic and monitored accordingly.
Zero Trust grants access only to authenticated users and their designated applications. That is with specific rights, privileges and restrictions. So, it is just enough access to perform their jobs, but nothing else.
Zero Trust uses advanced technologies. That includes behavioral analytics, sandboxing, anomaly detection, and machine learning. This is to monitor all network activity for the activity that would indicate a security breach of some form is taking place.
SD-WAN
Security is a top concern for WAN connectivity. Traditional WAN architectures rely on perimeter firewall security to protect the organization’s network. But these perimeter-only security measures are no longer sufficient.
Attackers have too many avenues to breach the perimeter, even if they are stopped at the perimeter. So, they can still wreak havoc inside the environment.

SD-WAN creates private connections between remote users and their applications. This is as well as between remote sites and the corporate network. The SD-WAN solution should provide comprehensive visibility and control of all traffic that traverses the WAN.
So, it includes monitoring, controlling, and auditing all outbound traffic. SD-WANs leverage central policy management for a more secure approach to network access control. But this is rather than the traditional segmentation of resources that leaves gaps in overall security.
Security Encryption
SD-WANs use encryption of sensitive data as well as authentication and authorization of all users accessing WAN resources. Application policies also can be enforced over this encrypted infrastructure with granular controls over specific applications and users. This results in more complete protection at a reduced cost.
Authentication is critical to ensure that only those authenticated entities with a need to access the network can do so. Zero Trust Access Enforcement (ZTAE) uses advanced technologies including behavioral analytics, sandboxing, and anomaly detection. But also machine learning to monitor all network activity for the activity that would indicate a security breach of some form is taking place.

ZTAE is designed not just to stop these attempts but also to identify what has been done so that it can be contained quickly and effectively.
