- [Instructor] We've already discussed how network segmentation is a valuable security control. We can use isolation to segregate systems of different security levels into different zones of security, allowing us to reduce the risk that a compromise in a system of a lower security level will impact a system at a higher security level. This is a sound and respected management practice. Isolation can also be used at an extreme level for highly sensitive systems. A server containing particularly sensitive information can be placed in a security zone by itself, with access into and out of that zone carefully managed. This complete system isolation creates a lot of overhead, But it's also a very robust security control. But the use of network segmentation raises practical questions. How can administrators work with systems that are isolated without having to keep connecting their own systems to different networks? That's where…
