Network segmentation enhances security and performance
Network segmentation divides a larger network into smaller, isolated segments to improve security and reduce the attack surface.

Network segmentation divides a larger network into smaller, isolated segments to improve security and reduce the attack surface.
Context
Businesses face growing cybersecurity threats that can compromise sensitive data and disrupt operations in this increasingly interconnected world. One effective strategy to mitigate these risks is network segmentation, which involves dividing a larger network into smaller, manageable parts. This approach not only enhances security but also improves network performance by isolating issues and controlling data flow. As organisations seek robust solutions to protect their digital assets, understanding the principles and benefits of network segmentation becomes essential.

Analysis
Network segmentation is an architectural approach that divides a network into multiple segments or subnets, each acting as its own small network. This allows network administrators to control the flow of network traffic between subnets based on granular policies. Organisations use segmentation to improve monitoring, boost performance, localise technical issues and enhance security.

Individuals within the perimeter were assumed to be trustworthy and therefore not a threat. Thus, they were subject to few restrictions on their ability to access information.
Key Points
- Network segmentation divides a larger network into smaller, isolated segments to improve security and reduce the attack surface.
- It enhances performance by limiting broadcast traffic and allowing for tailored security policies for different segments.
- Proper implementation can help in compliance with regulations and improve incident response times during security breaches.
Actions
Pending intelligence enrichment.
