The critical technique of Network Segmentation mitigates risk for Critical Infrastructure and Operational Technology networks, as demonstrated by CISA’s endorsement of segmentation. Many cyber attacks have turned from simple user compromise to devastating shutdowns and ransomware because the hackers use lateral movement once a single machine or device is compromised. Here’s why:
Dividing a network into smaller, manageable segments reduces the attack surface. This subdivision limits the spread of cyber threats, ensuring that a breach in one segment does not compromise the entire network. The advent of IoT, cloud computing, and remote work models has expanded the traditional network perimeter, introducing new vulnerabilities and complexities. Network segmentation delivers better separation between OT and IT networks, ensuring that user compromises in the IT domain do not leak into the operational network.
In networks with thousands of users and devices, the complexity of firewall and ACL configuration management is a significant security vulnerability. Traditional segmentation methods are generally static and don’t easily accommodate the dynamic nature of today’s OT networks, where devices and users require flexible access to resources. VLANs and ACLs lack the depth in contextual control that OT networks need for operations. They don’t typically consider user identity or real-time context in granting access, which can lead to over-privileged access or security gaps.
Network segmentation supports numerous regulatory standards, which require separating certain types of data and systems to pass risk assessments and maintain security compliance.
Disparate systems and manual configurations lead to consistency and make meeting regulatory data protection and privacy requirements more complex.
BlastShield™ exceeds traditional segmentation by advancing the concept of microsegmentation as a superior security alternative. Unlike broad segmentation strategies, BlastShield’s microsegmentation allows for incredibly detailed control, segmenting networks down to the level of individual devices, systems, protocols, or users. By isolating network segments, BlastShield effectively prevents the lateral movement of threats within the network, a critical defense mechanism against external and internal threats. BlastShield™ policy changes take effect in real-time, facilitating dynamic and flexible policy enforcement during emergencies or administration changes. Unlike many solutions that use ACLs and VLANs, microsegmentation scales effortlessly to large OT environments. With its detailed segmentation capabilities, BlastShield™ aids in compliance with stringent regulatory standards, offering necessary tools to protect sensitive data and ensure privacy. BlastShield’s microsegmentation solution is innovative, future-ready network security.
The BlastShield™ Gateway and Host Agent are pivotal in facilitating advanced network segmentation through microsegmentation. These components work in tandem to create a highly secure and efficiently segmented network environment.
