How to improve the security of smart building networks


1. Consolidate remote access.

Buildings often deploy multiple gap networks. As these networks are physically completely different, this means that data cannot be transferred from one network to another and they need to implement separate remote access entry points, such as virtual special networks. The outcome of a remote access strategy may be quite different from a network security perspective.

The combination of multiple gapped networks into a physical network with a single method of remote access is becoming an increasingly popular remedy. From a network security perspective, the strategy can improve visibility, authentication control, unified security policy management and virtualisation accounting software hong kong.

2. Secure network zones.

Different IT/OT systems can remain isolated even as they integrate gap networks to improve network security controls and limit horizontal movement in the event of a breach. Modern Ip networks are often integrated with firewalls on the fourth to seventh floors. These firewalls can identify the type of traffic in each network packet and can be used to create logical security zones and restrict inter-zone communication at a granular level. Restricting inter-area communication reduces overall network security risk by limiting the ability of hackers to move through the network custom part manufacturer.

3. Monitor network threats.

Visibility is an important component of the modern cyber security landscape. A compromised IT/OT device or platform often begins to communicate with a zombie web server, indicating that the device or platform has been compromised. Without proper threat monitoring, a hacked device can exist on the network indefinitely and may affect other systems.

To solve this problem, proper security visibility is required. The latest network threat monitoring platform, known as Network Detection and Response (NDR). To monitor all traffic passing through, security tools are installed on the network. ndr also classifies and baselines all data flows on the building network. ndr uses artificial intelligence to identify whether a device or group of devices is experiencing unexpected changes in communication that indicate a possible vulnerability in the network or device.

4. Patching management.

OT and IoT patch management is critical to IT maintenance and monitoring. The IT security team must be aware of the security patch versions for each hardware and software component included in the smart building. The earlier the latest security patches are available, the less likely it is that damage will occur Miner mall.

5. Monitor and restrict access.

Smart buildings introduce IoT sensors, smart surveillance cameras, door controllers and a host of other new hardware and software devices that need to be managed and maintained. While many platforms and systems allow local user names and passwords to manage access, this can lead to lost, stolen or updated passwords. Microsoft's AD and RADIUS protocols are two common methods of managing accounts and providing access control to restrict which systems an account can communicate with.
