Community of interest (computer security)
computer networking technique of segregation of resources
Community of interest (COI or CoI) is a means in which network assets and or network users are segregated by some technological means for some established purpose, a strategy in the realm of computer security, itself a subset of security engineering.
Typically, COIs are set up to protect a network infrastructure from a group or groups of users who are performing some esoteric functions. They are also designed to protect their user community from the rest of the enclave user population. Not only does this refer to the simplicity of the network, but it also includes a group of people that come together on different social networks to share data.
On Wikipedia, Facebook, YouTube and many more sites, people come together as a community of interest to work toward a common goal, learn from each other, critique each other and share ideas. These user groups are separated into categories and segregated into logical groups. There can be professional groups, health groups that include people interested in specific diets, business groups, self-start up groups and countless other categories. A COI is a group of professionals and advisors that share business insights, technical expertise, challenges, and perspectives.
Definition
A COI can be defined as a logical or physical grouping of network devices or users with access to information that should not be made available to the general user population on a LAN or WAN infrastructure. A COI can be used to provide multiple levels of protection for a LAN or WAN infrastructure from the activities within a COI. A COI can consist of a logical perimeter around the community (or enclave).
The public source identifies “Community of interest (computer security)” as computer networking technique of segregation of resources. This brief keeps that definition visible, then builds a research path around Community, interest and computer.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Community of interest (computer security)”, the useful work is to connect “computer networking technique of segregation of resources” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 14, 2026. The linked authority identifier is Q1120661. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
