Description: Network isolation refers to the separation of network traffic to enhance security. This practice involves creating barriers that limit communication between different segments of a network, helping to prevent unauthorized access and contain potential security breaches. Isolation can be physical, through the creation of separate networks, or logical, using technologies such as VLANs (Virtual Local Area Networks) and firewalls. By implementing network isolation, organizations can protect sensitive data and critical systems, ensuring that even if one segment of the network is compromised, the damage is contained and does not spread to other areas. This strategy is essential in environments where security is a priority, such as in financial services, healthcare, and critical infrastructure sectors. Additionally, network isolation is a key component in broader security architectures, such as the Zero Trust model, which assumes that threats can exist both inside and outside the network and therefore requires continuous verification of every access and communication.
