Define 'network segmentation' in SonicWall setups.

Network segmentation in SonicWall setups refers to the practice of dividing a larger network into smaller, isolated parts. This approach enhances overall security and performance by limiting broadcast traffic and creating barriers against potential security threats. By using segmentation, organizations can enforce stricter security policies tailored for each segment, ensuring that sensitive data is isolated and less accessible to unauthorized users.

Additionally, segmented networks can lead to improved performance because they reduce the amount of broadcast traffic that can bog down a network, allowing for more efficient data handling and reducing possible vulnerabilities. Each segment can have specific security measures and monitoring, which can lead to quicker detection of potential threats and better response strategies. This practice is foundational in building a secure and efficient network infrastructure.
