In today’s world, information security and network security are vital for organizations and companies. Security threats are becoming more sophisticated and new day by day, and modern and advanced security solutions are needed to protect data and networks. We are proud to provide solutions that help organizations improve their information security.
NSX-T Data Center A platform for network security
NSX-T Data Center from VMware is a network virtualization platform designed to virtualize and manage virtual networks in cloud-based, data center, and software-defined data center networks (SDN) environments. This platform provides organizations with unique security features to protect their sensitive information. Here are some of these features:
Network isolation
NSX-T allows organizations to place different networks on a common physical infrastructure and yet keep them isolated from each other. This means that data movement between networks is restricted and access to network resources is controlled by different users. This network isolation provides an improved network.
To understand better, suppose that an organization has two separate networks: the administrative network and the development environment network. With NSX-T, these two networks can be located on a common physical infrastructure (such as physical servers and switches). But this is where network isolation comes in handy.
With NSX-T enabled, data moving from one network to another is managed by NSX-T at the Subnet Network (SDN) layer. This means that the movement of data between networks is restricted and access to network resources by different users is possible only with specific permissions.
For example, in the case of virtual machines or containers, you can specify that a container cannot access the development network from the administration network, even if both are located on the same physical infrastructure. This precise control over access to network resources increases network security and prevents the possibility of unauthorized access attacks.
In general, through NSX-T, you can configure different networks with different and separate access rules, thus improving network security.
Microsegmentation
One of the outstanding features of NSX-T is micro-segmentation. This feature allows organizations to divide the network into smaller segments or “microsegments”. Each microsegment can have its own custom security rules and restrict access by other network segments. This allows organizations to limit network attacks to narrower segments and strengthen network security.
In NSX-T, microsegments can be defined based on a variety of criteria, including:
Based on the role
You may want to define which users or user groups have access to which part of the network. For example, the development team may have access to specific parts of the network that are not accessible to the administrative team.
Based on resources and programs
This allows you to determine which parts of the network can access which resources or applications. In other words, this feature gives you the power to determine which parts of your network can access sensitive applications and which can’t.
Based on physical segments or microsegments
Here, you can define different micro-segments based on your needs. For example, one microsegment can be defined for the finance team, another microsegment for the development team, and another microsegment for the executive team. Each of these micro-segments can have its own independent access and security rules.
By using this feature, organizations can limit network attacks to narrower segments. For example, if an invasion or attack occurs in a microsegment, this threat is limited to that microsegment only and is prevented from spreading to other parts of the network. This allows organizations to strengthen their network security and prevent inappropriate access to resources.
Network encryption
NSX-T enables organizations to encrypt network data. This capability means that data that is transmitted between networks or microsegments can be encrypted. This makes it unintelligible to unauthorized persons if the network data is accessed.
Firewall features
One of the outstanding features of the NSX-T is its advanced firewall capabilities. This feature allows organizations to define custom firewall rules to control access to network resources. Thus, it enables organizations to closely monitor network traffic and protect against various security threats and attacks.
how it works
Define firewall rules
First, organizations can define custom firewall rules. These rules include identifiers such as allowed sources, destinations, ports, protocols, and other values for network traffic.
Traffic check
As a network virtualization platform, NSX-T closely monitors network traffic. When traffic is sent from a source to a destination, firewall rules are applied to assign access qualifiers to the traffic.
Protection against attacks and threats
By applying firewall rules, organizations can protect against various security threats and attacks. For example, if an inappropriate traffic or a known attack is detected by the firewall rules, that traffic can be blocked or redirected.
Advantages
Strict access control
This feature allows you to precisely determine which resources have access to which destinations. This allows you to control network traffic and prevent inappropriate access.
Protection against threats
With custom firewall rules, you can protect against various attacks and security threats. This allows you to avoid various attacks.
Advanced facilities
The NSX-T has advanced firewall features including Intrusion Detection and Prevention (IDPS). This allows you to proactively monitor network traffic and take action if any suspicious or aggressive activity is detected.
Altogether, these advanced firewall features in NSX-T enable organizations to strengthen their network security and prevent network security threats.
Central security management
NSX-T enables centralized security management. This capability allows organizations to define security rules in a central location and apply them to all network resources. This allows organizations to quickly and universally apply security changes and manage security configurations.
Conclusion
Using NSX-T Data Center as a network virtualization platform can help organizations strengthen their network security and improve the protection of network resources against security threats. This platform has the ability to provide advanced security features and facilities that are effective against modern threats.
