Private Cloud Security: CloudGuard IaaS supports VMware’s new NSX-T 2.4 release

Published by Jonathan Maresky, Product Marketing Manager, Cloudguard IaaS, May 8th, 2019

 

VMware has been taking real action to back up CEO Pat Gelsinger’s assertion that hybrid-cloud is the new norm, most recently through updates to their NSX-T Data Center network virtualization platform for on-prem and cloud environments. NSX-T version 2.4 was a major milestone that saw the introduction of new advanced security capabilities.

 

Check Point was a design partner for the new version, which is fully supported by Check Point CloudGuard IaaS. This makes sense considering the close relationship between Check Point and VMware, and that CloudGuard was the first VMware partner product to be certified for NSX-T North/South service insertion.

CloudGuard IaaS is the first security partner to be certified on NSX-T 2.4.

Let’s dive into a few of the security enhancements in NSX-T version 2.4 and how CloudGuard IaaS uses them to harden private cloud security for Check Point customers.

Network Topology

CloudGuard supports NSX-T Inventory.

CloudGuard reads the inventory from NSX and allows the security operator to use objects from the inventory as part of the security policy. CloudGuard watches these objects and updates the gateway regarding any change that might occur on the NSX side.

NSX-T v2.4 allows the dynamic export of network topology, providing CloudGuard with immediate access to all network configuration changes.

Dynamic, Context-Based Grouping

NSX has rich contextual knowledge of the workloads it’s protecting. Instead of using grouping and rules based on where something is in the network, with NSX customers can use constructs based on specific characteristics of the workload, including for example the workload’s Operating System or name. By applying Security Tags, workloads can also be grouped based on criteria such as the function of the application, the application tier the workload is part of, the security posture, regulatory requirements or the environment the application is deployed in.  Through the use of Security Tags, policies can be applied automatically to new workloads, thus reducing manual administrative overhead. For example, when you add a new VM: as soon as you apply a meaningful tag to the new VM, it automatically assumes the relevant policies of the tag’s groups.

You can also apply these policies automatically to new workloads, thus reducing manual administrative overhead.

Policy-Based Service Insertion

Using VMware NSX-T and Check Point together provides strong security for North-South traffic entering the data center from the outside. This is done by connecting the CloudGuard IaaS security gateway to the T0-T1 router. NSX handles the deployment, plumbing and selective redirection of traffic to the CloudGuard IaaS security gateway.

CloudGuard IaaS provides powerful private cloud security features such as Firewall, Intrusion Prevention System, Anti-Bot, Antivirus, Application Control, and URL Filtering; as well as Threat Emulation and Threat Extraction for complete protection against the most sophisticated threats and zero-day vulnerabilities.

But what about East-West traffic?

Firewalls are conceptually sound, but execution often leaves network and security teams scrambling to patch flaws and fix mistakes that hackers have already discovered and exploited. Worse, once bad data packets such as malware enter into the network they may have unimpeded access to that “East-West” traffic inside the network.”

In other words, a breach of a single network can propagate across the data center, compromising all applications. Even attacks on low priority services can expose critical or sensitive systems.

With the Distributed Firewall, NSX-T enables micro-segmentation, enabling customers to provide granular firewalling for East-West traffic within the datacenter.

VMware NSX-T 2.4 introduces the enhancement of Policy-Based Service Insertion enabling partner solutions like Check Point CloudGuard to enhance the security of East-West traffic, without making changes in the topology.

Checkpoint CloudGuard IaaS is integrating with NSX-T 2.4 East-West Service Insertion in order to provide robust protection of lateral traffic between different entities inside the cloud deployment. This lateral traffic may also be automatically redirected according to context-aware policies, as explained above.
