The technique of separating distinct areas of a network to improve security and performance is known as microsegmentation. It entails the creation of tiny, independent parts or zones within a network, each with its own security boundary. Microsegmentation is significant because it helps improve the security and performance of networks.
Microsegmentation market has been increasing worldwide because of the rising usage of cloud-based services, increased worries about data breaches and cyberattacks, and the demand for better security solutions across enterprises. The number of data breaches grew to 4,100 million in the first half of 2019, according to Coherent Market Insights’ estimate. These reasons are projected to boost demand for microsegmentation, pushing the market to new heights.

How does microsegmentation work?
Microsegmentation protects applications by permitting specific application traffic while blocking all other traffic by default. The cornerstone for building a Zero Trust security strategy for application workloads in the data center and cloud is microsegmentation.
Traditional firewalls, intrusion prevention systems (IPS), and other security systems are built to inspect and safeguard traffic flowing into the data center. Microsegmentation allows businesses more control over the expanding quantity of communication that takes place between servers, avoiding perimeter-based security measures. If a compromise occurs, microsegmentation prevents hackers from lateral network research.

What are the main obstacles to microsegmentation implementation?

Microsegmentation has its own set of obstacles to overcome:

Infrastructure adaptation
Network structure and architecture will need to be changed as part of the implementation. A specified method based on traffic relationship analysis is required to reduce costly effort and the chance of failure.

Procedure adaptation
Whether it’s the process of seeking additional connections or the process of installing new systems, a holistic perspective and improvement of the processes are necessary. The procedures must be improved and automated to the point where the extra measures can be applied practically. Management must support the partially newly necessary or newly allocated responsibilities.

Integration with existing tools

Automation and the use of relevant tools should make it as simple as possible to adopt extra
security measures and support staff in their new roles. Microsegmentation is only effective
with appropriate orchestration and open interface integration with current tools.

Top microsegmentation advantages

Cloud workload security

Microsegmentation reduces the attack surface while also giving granular visibility into workload interconnections. It also protects workloads and applications that are dispersed across many cloud data centers. The system also provides real-time insight into any questionable behavior, allowing security experts to detect and respond to suspicious behavior in a timely manner.

Easy compliance
Microsegmentation makes obligatory compliance standards easier to follow. The capacity of microsegmentation to specify the scope and restrict lateral movement helps businesses in meeting a variety of regulatory demands.

Simplicity in security
A high-quality micro segmentation solution allows you to design security templates that govern user access to apps and databases. This can help you save a lot of time. Companies can use the templates for standard security and compliance on every environment established or changed, rather than spending hours undertaking laborious manual setup work.

App access security
Microsegmentation allows for secure application access, providing appropriate access to appropriate functions or resources. For companies with various locations, the ability to give visibility across all remote access points is very important. Security teams can utilize a level two microsegmentation technique to develop flexible policy restrictions that respond to the user’s location, identity, and role.

Improved damage control
Security breaches are reduced when separated workloads serve as security zones. Security policies implemented at the workload level limit potentially detrimental lateral movement away from the attack vector in the event of an incident. If there are any security policy breaches, administrators can readily detect them using real-time notifications, allowing them to alter security rules as needed.

Use cases for microsegmentation

Soft asset protection

Soft assets, such as customer data, employee data, financial data, and intellectual property, must be protected. Microsegmentation adds an extra layer of protection to soft assets.

Response to an incident
Microsegmentation also stops threats from moving between segments and provides log data. As a result, it’s ideal for incident response and identifying security vulnerabilities.

Cloud management
Microsegmentation also secures applications that span various cloud deployments by allowing businesses to enforce consistent security policies across numerous data centers and service providers.

Final thoughts

Monitoring traffic and enforcing regulations to maintain a consistent cybersecurity posture becomes increasingly difficult as the network gets larger and more complicated. Security teams can gain deep visibility and enforce policies that follow workloads across distributed and dynamic environments.

Microsegmentation is becoming more popular among businesses looking to secure their digital assets. It greatly reduces the damage a cybercriminal can do by reducing the network attack surface. If you don’t want to put your company’s security at risk, you should take a look at microsegmentation and decide if it would work well for you.
