Cybersecurity Checklist For BAS: Why Its Vital In Building Automation System?

When we talk about the for BAS, uh well, this is a thing, y'know. BAS, that's. Now in a automation system this like a big or is a particularly critical core system similar to that building, controlling the operation of various equipment, lighting, air conditioning facilities, and safety system equipment in the building. If the network security of this system is in chaos, the consequences will be unimaginable that the operation of these facilities in the entire building will be completely in chaos and may even threaten personal safety.

Next, let’s explain the key content specifically for BAS. First of all, in the equipment authentication, you must do a good job in verifying the identity of the equipment connected to the BAS. If the equipment is unknown or the identity is wrong, let it directly connect to the system, which is equivalent to opening the portal and how others enter and exit. The entire system may be maliciously controlled instantly. Secondly, network segmentation, we must not forget this. We should organize each BAS network to clearly segment this segmentation, which will help reduce the chance of bad situations such as bad situations that will spread to other areas after being attacked. Next is security updates and maintenance. The software and devices of BAS must be updated frequently. You should know that some offensive threats are mainly aimed at vulnerabilities in the devices. This will make this situation last longer, no matter how serious it may be, it will lay a bombshell for the safety of various equipment in the building! There is also the data encryption and other links, which require confidentiality to all the BAS processing and transmission of data. Once such particularly basic and critical data is illegally stolen or changed, the impact will directly radiate to the entire building's entire control operation. As for access control, it cannot be left behind. The rights of the people who can get access are limited. Zhang San and Li Si can not touch them. You should know that if you have more bad intentions, you will have more risks!

Regarding some details that everyone is curious about here, we have done some Q&A sessions. For example, people often ask why security audits have to be placed in for BAS? So we say that security audit is used to check whether security vulnerabilities have created new variants and problems have occurred. If you are not diligent and do not pay attention to many bad situations, you will accumulate more and more hidden dangers.

Some people may ask, how to control and master the matter in the Internet and external access to those buildings? This is not very accurate. The scale of the gold-dividing point is the best. Only legal and special-purpose network tools from our series of review and license companies allow certain special interfaces, such as special maintenance and engineers who handle necessary matters, can enter and exit the network port and enter the BAS. The kind of connection that suddenly appears and looks unnatural is best to keep it out directly. No matter how clever you want to break through, don’t eat it, and don’t let it go if you don’t let it touch!

Some people may be curious about the prevention measures for online virus attacks and whether it is very different from preventing viruses in the home to prevent computers from viruses? To be honest, this difference is quite big. In fact, the BAS system is very core and the operation of ordinary home or office network equipment is different. BAS in a building will be much more complex, involving the coordinated operation of different types of jobs and the types of data are particularly diverse and special. We must be more professional and strict in dealing with online viruses. This has its own unique requirements in strategy and protection system formulation, so we have to do something with a simple little guard at home.

Someone has also consulted me whether I need to simulate a comprehensive risk test frequently during my daily operation. Of course, if I need to conduct these special tests on a regular basis, those risks hidden in the dark can't be discovered at all like a kitten hiding in a black hole. Later, if I was suddenly exposed and exposed, this is a big blow. We can test it regularly and prevent it early and detect it in time.

In my personal opinion, for BAS is extremely important. If you want a building function to run stably and safely, the security of the entire system is the cornerstone of this big game. If you do all aspects of network security, and you are confused about the hidden dangers of various system loopholes and hidden dangers, this building may have a bad experience in life or may cause some outrageous problems from time to time. Some accidents may even occur, which will have some bad effects on people's health and life. We must pay attention to these grass and trees.
