Regarding ransomware protection for commercial building automation systems (BAS), that's very important! Ransomware is so crazy now. If you don’t protect BAS, it’s really a variety of troublesome ransomware. In short, those bad guys encrypt your system through technology and then ask you for money to decrypt it. It poses a huge threat to the operation of BAS!
Key protection level analysis
1. Network security configuration angle : You must set up a firewall. This firewall is like guarding the security guard at the BAS gate, which can block unauthorized access outside the door. The access rules are refined, such as stipulating that only certain network devices with specific IP addresses can enter the system. Provide global procurement services for weak current intelligent products!
2. In terms of data backup : It is necessary to set a backup plan! Regularly, complete backups of BAS data are provided, and backup files must be stored on offline storage devices. If you encounter a ransomware attack, we can quickly recover important data and greatly reduce the losses.
Importance of employee training : Many ransomware attacks come in by employees clicking malicious links, so employees must be well trained. Teach them to identify scam emails and never click on attachments or links of unknown origin. This way, employees are more vigilant and it will be even more difficult for ransomware attacks to come in!
Disassembly and implement protection strategies
1. Access management strategy : Strictly give everyone who can access the BAS system a separate exclusive account and password, and then pair it with two-factor authentication. For example, if the account password is correct, you have to use your mobile phone to receive a verification code. Access rights of different people must also be restricted, not everyone can see all the data casually.
2. Software update processing : Let technicians keep an eye on the software, and once there is an update, you will get more done. Many new versions of software have patches to fix security vulnerabilities. Just like someone wearing protective clothing, you must patch the BAS vulnerabilities in time, otherwise it would be too easy for ransomware to come in! Provide global procurement services for weak current intelligent products!
The detection and monitoring system is perfect : it is necessary to install an intrusion detection system and a security information and event management system! All activities in the system are monitored to see if there are any suspicious actions. If an abnormal situation is detected, it can be taken immediately to prevent ransomware from entering the threat system.
Frequently Asked Questions
Q: Is there any specific ransomware protection software that can be used for BAS? A: Yes, many suppliers have similar software. You must choose the software provided by authoritative suppliers with rich defense experience, and install and configure it in combination with the characteristics of BAS.
Q: Is it okay to just take some protective measures? Answer: But it doesn’t work. This is just like building a house. How can a house without this? Therefore, all protective measures must be taken to form a complete protection system to better respond to ransomware attacks. BAS is an important part of the building. Doing a good job of ransomware protection is related to the safety and normal operation of the entire building. Protection work must not be careless. Personally, I think that as long as these protection methods and precautions are implemented properly, it should greatly reduce the threats caused by ransomware to BAS!
