The hotel is not a group, but three main subjects: the occupants are temporary and the outside network is the dominant; employees have to touch the business system; locks, passenger controls, cameras, Pos, these things should be in their own safe areas. Combining them into one network is the most common structural risk of wireless hotels. Three networks are separated from each other, so that the boundaries are clear. One of the two types of problems does not drag down the others, which is the highest output of hotel wireless security.
The network can't touch the employee business system.
The network of visitors is a network that is limited in speed, restricted in scope and inaccessible to the Internet. It does not allow public areas to be connected to the network, which is convenient and easy to do: it allows outsiders to touch PMS and finance systems. The isolation of the network is the first wall of wireless hotel security. This wall is loose, and more certification cannot be made up, because the attackers need no decertification at all and they just follow the network.
The feds are going to be in a separate safe area.
Door locks, passenger controls, cameras, POS machines that mix with the occupants on the same floor network may touch these devices horizontally once a residential device is controlled. The joint equipment should be in an independent safe area and deal only with the backstage of the communication without being exposed directly to the network. They do not need to access the Internet, but they just need to speak to their own service end.
Staff network protection sensitive system
The network has the highest levels of authority and segregation on sensitive systems such as PMS, office, finance. It is logically or even physically isolated from the network, and it should not be connected to its own mobile phones. A looser boundary of the network would leave a seamless door to the hotel core system.
The visitors and the guests are different.
The hotel also has outsiders and restaurant visitors who, unlike the official guests, should go to a more restricted network. Residents are given regular access by their names and numbers, and visitors only give them basic out-of-the-box.
Isolation by VLAN plus post-certification strategy
The isolation is achieved by different SSIDs for VLAN, and the certification followed a role-based strategy route: residents walk through the outer net, employees through business, and goods into secure areas. In conjunction with NE-80, this type of gateways are controlled and collected, segregation is both logical and tactically effective.
Isolation is a problem.
The isolation is designed to monitor whether it actually works: if there are any unusual traffic in the network to the employee system, if the domain of the object is detected by outside equipment. It often goes silent and cannot be detected without monitoring. If an anomaly is monitored, it can be reported and disposed of, it cannot be done.
Compliance basis for segregation
Separation of residents, employees, and associates is not just a matter of safety practices but also of compliance. The employee business system and the host network are mixed up with clear questions in waiting and internal compliance checks. Segregation is done, the section in compliance checks is stable, and responsibility is clear when it happens.
I need to isolate before authentication.
The pre-certification area places unincorporated equipment in a restricted pre-certification area: wireless but not certified, access to the authentication page, no business systems, and no internal network. The pre-certification area first locks the non-intocidentised device into a cage before it is released by role. This step is often ignored, but it is the first level of isolation, leaving only a small amount of access to the attack.
The border is being separated and adjusted to operational requirements.
The hotel's business changes: smart guest rooms, new POSs, and take-out containers are added, and these new devices are all fed into the right net. Isolated borders are not always fixed once, and each time a new operation is rechecked for which network it is located. Border drifting is a common reason for isolation to fail, with additional equipment being used directly to connect the Internet, and three networks have been created over time.
Isolation and authentication are not alternatives.
The only thing that can be verified is that you are the one who gives you access, and that separates between networks with different competencies. The process of certification does not lead to segregation, and the occupants and employees are still in the same network, with no further detail or horizontal movement; it is only isolation without authentication, and no one who enters the net knows about it, and there is no way to comply with it. Together, identity and boundaries are established.
The three networks of tenants, employees, and property are cleared of boundaries, so the hotel is wireless from a network where everyone can wander to one where there are different routes. This step goes ahead, with many fewer security incidents behind it, and less responsibility.
