Our company is a small agro-industrial complex with three pig farms, a dairy farm, and three meat processing plants. In addition, our group owns a restaurant, a ceramics factory, and a chain of bookstores. Our information network includes 300 personal computers, not counting special industrial ones. But we only use 50 full licenses. The system is managed by a single operator, for whom this is not the main type of work. In addition to computers included in the domain, we use PC monitoring outside the domain via an external Internet connection.
