Purpose of Microsegmentation in a Cloud Environment

The digitization of every interaction between a company’s employees, clients, and partners has made applications the focal point of digital transformation. Scale, speed, agility, and availability of apps are also key factors to staying up with changing business requirements. Due to the requirement that all or some of an organization’s applications be delivered via the cloud today, fast cloud adoption has become a significant component of digital transformation. 

However, moving applications to one or more clouds also necessitates dealing with the associated cyber security threats. Data protection in the cloud is crucial for businesses of all sizes in the aftermath of periodic high-profile hacks and ransomware attacks like WannaCry.

Each cloud instance and service must be in isolation to reduce the risk of data compromise, regardless of whether a business uses a private, hybrid, or public cloud infrastructure or provides cloud services to third parties. Networking hardware and firewalls separate and segment physical servers and other devices in a typical network. 

Discovering Assets

Micro-segmentation helps reduce the harm a compromised cloud asset can do. Instead of a large data breach that affects many areas of the company or many customers in a multi-tenant service, it can minimize the impact of a localized issue that can be resolved swiftly.

Knowing which assets are in the cloud environment is vital before deciding on protections and security procedures. Additionally, real-time synchronization between the business platforms and the micro-segmentation is a prerequisite for additions, revisions, or decommissioning.

Security typically surrounds corporate assets in conventional micro-segmentation logic. Thus, it becomes crucial to be on the lookout for any redundancies or omissions. However, asset discovery in vast or complicated networks may be more effective than using only human resources. Some micro-segmentation solutions can sync up data from a cloud management platform like vCenter to reduce this workload.

Modeling of Applications and Services

The next stage is application and service modeling when we decide which cloud assets need micro-segmentation. Considering the potential effects of a micro-segmentation solution on the flow of company processes is vital.

Imagine setting up security cameras in a building housing shared offices. Cameras shouldn’t be present in restrooms, for example, as this would disrupt the flow of activities. Additionally, companies should disable recordings in some situations and cameras should not capture potentially sensitive information. For example, things displayed on laptop screens.

A dashboard display that offers information and details about assets, including their relationships, is typically provided by a micro-segmentation system.

Implementing Safety

Micro-segmentation in the cloud can decide how to handle various types of traffic in a certain environment through blacklist and whitelist policies. Alongside, a deep comprehension of traffic patterns. The dashboard gives security teams the ability to adjust policies as necessary. Moreover, it displays traffic in a simple and granular manner. Additionally, a full range of Layer 2 to 7 safeguards including IPS, application security, antivirus, Web filtering, as well as other security measures are frequently an aspect of micro-segmentation solutions.

Policy Enhancements

It is advantageous to frequently review and update existing policies, just like with any multi-step process. For instance, financial guidelines might have altered somewhat, or human resources might introduce a new timekeeping technology that modifies the connections between virtualized assets.

It is simple to monitor how assets are functioning and what kinds of interactions they are having thanks to a micro-segmentation solution that can display asset information at a detailed level. The micro-segmentation dashboard can assist in identifying areas where we can optimize policies by comparing the present state with the ideal flow of security and business processes.

Adopt Micro-Segmentation to Quicken Cloud Adoption

Cloud adoption and security must occur simultaneously in order for digital transformation to be successful. Therefore, the crucial query is: How can businesses move to the cloud while maintaining security?

Let’s return to segmentation, the fundamental security principle, to try to address this. The network often segments into internal, DMZ, and external zones using a firewall, and policies govern the traffic between these zones. ACL/VLANs are also set up to divide internal networks similarly. However, these methods are inadequate to safeguard applications based in the cloud, where East-West traffic and North-South traffic pose a threat. Micro-segmentation offers to protect cloud apps by utilizing new technologies while adhering to the same fundamental security principle. It is a solution to all our cloud-related security needs.
