What news is available on Zero Trust Network Access?
Zero Trust Network Access is a new approach to security and access control in which the user or device is not implicitly trusted. Instead, network access is granted to the resources based on the identity of that user or device. This is typically through the use of multi-factor authentication and the policies in place on both the user or device and on the network itself.
ZTNA enables businesses to see all users and devices, what they are doing, where they are going, and where they have been. This visibility enables a much better understanding of how users are interacting with critical assets and sensitive data. This includes as well as how threats can be detected before they have a real impact on an organization’s business.
Also, Zero Trust Network Access is designed to protect data from malicious insiders as well as external attackers. It can prevent a breach before it happens, significantly reducing IT costs and increasing business agility. Also, Zero Trust Network Access provides visibility into where information assets reside.
This is to enable more effective security policy management across endpoints, mobile devices, applications, and APIs. ZTNA is a network security concept that changes the access control paradigm. This is from the traditional authentication and authorization methods to a model.
Since it is the network access is granted based on the identity of the user or device. Also, the policies are in place on both the user or device and on the network itself. Hence, ZTNA focuses on protecting the organization’s information assets by using a layered approach to detect and prevent all types of attacks.
WAN Optimization
The goal of WAN optimization is to improve application performance. This is done by decreasing the amount of data traveling over the wide area network (WAN) between physical locations. This can be achieved by limiting the amount of data sent to the WAN.
Also, eliminating data from the WAN network. WAN optimization differs from compression in that it focuses on optimizing applications. This is based on their usage rather than compressing all data on the network regardless of its contents.
Moreover, WAN optimization appliances are typically installed at strategic locations along with a company’s WAN infrastructure. The two primary functions performed by these appliances are compression and caching. Caching allows local resources, such as application servers, to be accessed via centralized storage devices closer to end users.
WAN Optimization Appliances
This is especially useful for users who access content frequently, such as employees at a particular branch office. Compression reduces the amount of data being transmitted over the WAN by reducing redundancy in patterns of bits across multiple packets. This allows for more efficient transmission of information over the Wide Area Network (WAN).
Users may notice little difference in performance when accessing content served from local storage media. But significant improvement when accessing remote sites and applications. Due to its ability to improve performance and decrease bandwidth usage.
Moreover, many organizations deploy WAN optimization appliances between their servers and their clients. However, there are several disadvantages to using WAN optimization appliances. Because only a subset of traffic is optimized by WAN optimization appliances.
