Endpoint Isolation in Ransomware Protection with eScan EDR

Introduction

One of the greatest threats that businesses face today is ransomware. Endpoint Isolation is a powerful approach to prevent ransomware from spreading across the network. If one device becomes infected, isolating it can keep malware from spreading to other systems.

In this blog, we will discuss how Endpoint Isolation works, why it is important in ransomware defense, and how eScan EDR protects organizations from these destructive attacks.

Endpoint Isolation

When ransomware hits, it can spread rapidly. Left unchecked, it is capable of encrypting every business-critical file and demanding payment for their release. That’s where endpoint isolation comes into play.

What is Endpoint Isolation?

Endpoint isolation is the act of disconnecting an infected device from the larger network while still keeping it live in order to analyze the system. This keeps malware from reaching other systems while security teams locate and eliminate the threat.

Why Isolating Devices Stops Ransomware from Spreading

Here’s how endpoint isolation halts ransomware before it takes down your entire IT infrastructure:

• Halts ransomware in its tracks — Once an endpoint is isolated, ransomware can no longer communicate with other devices or servers.
• Impedes lateral movement — Numerous ransomware variants move within networks. Isolation severs this process.
• Mitigates risk — By isolating the compromised endpoint, sensitive files and databases are protected.
• Accelerates incident response — With endpoints isolated, IT teams can focus on investigating and responding to the attack without the threat of further spread.

Types of Endpoint Isolation

Different isolation techniques can be used depending on the situation:

1. Network Isolation – Disconnection of the affected asset from the Internet and internal network.
2. Process Isolation – Stopping processes with suspicious behavior to prevent malicious activity.
3. Application Isolation – Creating a Sandbox for the infected applications to limit systemwide damage.
4. User Account Isolation – Containing accounts that have already been compromised.

eScan Strategies

eScan EDR offers a modular endpoint isolation mechanism designed to prevent ransomware attacks. Here’s how it works:

1. Auto-Detection and Quarantine

• Real-time scanning – eScan keeps a watch on suspicious activities in real-time.
• Automated quarantine – In the event of ransomware-like behavior, the endpoint is instantly isolated, preventing additional infections.

2. Network Segmentation & Device Control

• Zero Trust – eScan makes certain that communication can only be between trusted endpoints on a network.
• USB device control policies – Prevents the use of unauthorized USB devices, which are often used to deliver a ransomware payload.

3. Advanced Threat Intelligence

• Threat intelligence – Understands the threat landscape and bad actors.
• Behavioral detection – Uses anomalous behavior analysis to identify unknown ransomware variants.

4. Data as of October 2023

• Automated remediation – eScan isolates the infected endpoint but allows access for forensic analysis.
• Group collaboration – The IT teams can work on solving the problem with no fear of subsequent infections.

Conclusion

The sophistication of ransomware attacks is only growing but Endpoint Isolation is a revolutionary approach to blocking them before they do damage. Organizations can avoid costly downtime and data loss by containing infections and preventing lateral movement.

eScan EDR provides a simple, quick, and effective mechanism for isolation of endpoints which maximizes ransomware protection for businesses. Don’t wait for an attack to come down. Be prepared and pair proactive Endpoint Isolation with your security strategy to ensure your network is secure today.
