Security breaches have infiltrated nearly every sector of the digital world in recent years. The access control system is often one of the most targeted network components, as it stores and processes sensitive user data. Therefore, it is vital to implement robust security protocols to protect access control systems from infiltration. One way to do this is to implement a two-factor authentication system for all access control staff members. Two-factor authentication requires a person to enter a username and password and then enter a unique numeric code that is sent to their smartphone. This greatly reduces the risk of a data breach at the access control software level. There are numerous examples of hackers infiltrating access control systems, usually through a networked device or software. For example, hackers have used malicious apps to gain backdoor access to some systems; they’ve also exploited vulnerabilities in older versions of vendor software or outdated firmware. In this post, we will explore some common pitfalls that can leave your access control system vulnerable to cyber threats. By following these best practices, you can secure your access control system and limit your organization’s exposure to hackers and other malicious actors. Read on to learn more.
Change the Default Network Passwords
The first step to securing an access control system is changing the default network passwords. While this might sound obvious, it’s a best practice that is often overlooked in the field. Be sure to change the default console password and login credentials as well. Also, ensure your network is segmented from other parts of your IT infrastructure, such as the internet-facing servers and databases. This segmentation will help protect your access control software from threats that might otherwise jump across these boundaries. Put a firewall between your network and the internet, and make sure all ports are closed except for a few essential protocols. Advanced firewalls, such as those that use artificial intelligence and machine learning, can actively block malware and other threats. They can also monitor network traffic, so if something looks suspicious, the firewall can alert you. Firewall hardware can be expensive, but some cloud-based options are much less expensive but may not be as secure.
Install the Latest Software Versions
Access control systems are often connected to machines with standard operating systems (like Windows), which are unfortunately particularly vulnerable to attack. Therefore, when you install the ACS, make sure you’re using the latest version of the software and that any patches or updates are current. If you’re using a cloud-based ACS, be aware of the security implications of sourcing data from the cloud. For example, some cloud providers might be subject to foreign government surveillance if their servers are located in certain jurisdictions.
Use Secure Protocols Where Possible
Access control systems often use standard internet protocols to communicate with connected computers, such as web browsers, mobile apps, and computers. While these protocols make sharing information easy, they also make systems more susceptible to attack. By enabling your systems to accept these protocols, you allow them to communicate with any computer on the internet. This greatly expands the potential reach of your access control systems by enabling anyone with an internet connection to use them instead of being limited to a select few with specific hardware. The best way to enable your access control software to accept standard internet protocols is by using an open-source platform that is freely available to the public. Therefore, consider using secure protocols that have built-in security features. For example, use HTTPS to secure web browsing sessions and/or virtual private network (VPN) connections. Be aware that not all protocols offer these security features. If a given protocol is unsecured, you might be able to run a virtual private gateway to add security features.
Don’t Email Passwords or Other Sensitive Data
Some organizations still send passwords and other sensitive data to users by email. While this might seem like an easy way to get control systems online quickly, it’s a major security risk. If you must send sensitive data by email, first encrypt the message using a digital or file-level encryption tool. These tools are designed to protect data from being stolen or accessed by unauthorized parties. Some file-level encryption software can also be used to encrypt emails before they are sent. Be sure to select a secure email service that offers encryption as one of its features. If you are communicating with partners or vendors overseas, make sure to check their email security policies. Often, these services do not have the same level of email security as American providers.
Use Strong Authentication Practices
Access control software often relies on log-in credentials to authenticate users and grant them access to building systems. However, these credentials can be stolen or guessed, granting unauthorized access to your buildings and whatever systems they have access to. Sign-in systems like two-factor authentication can prevent this by requiring a second form of verification before allowing access. This can be a code sent to your phone or generated by an authenticator app on your phone. Another option is a fingerprint scan. This is especially useful for facilities or systems that don’t have access to a mobile data connection. You can also use physical keys to grant access to buildings and systems. This prevents unauthorized access by limiting access to those who have a key. These credentials should use strong passwords and/or tokens (such as one-time passwords). Be sure to use multi-factor authentication (MFA) wherever possible. For example, some access control systems support MFA log-in using nearby smartphones (with an app installed). While MFA can’t guarantee that a breach won’t occur, it can greatly reduce the impact and likelihood of a successful attack.
Audit Everything
Finally, consider auditing your access control system and its connected devices regularly. Regular access control software audits are crucial because they allow you to discover any issues with your system before they become a major problem. Regular audits will allow you to catch any issues before they become critical and save you time and money. The best way to do this is to hire an outside firm or consultant to do an audit of your access control system every few years. An audit will allow them to look at your system, check its functionality, and test the system’s capacity to identify any issues within the system. An audit allows you to ask questions about how the system works and what steps you can take to improve efficiency. By doing regular access control system audits, you can also save money and time by identifying issues with your system early on. This can help you detect any potential security issues quickly and take steps to rectify them. Some vendors offer free or paid security audits of their products, so be sure to check with your vendor. If your vendor doesn’t offer this service, you can also outsource an audit to a third-party service.
Conclusion
The access control system is an increasingly important component of modern buildings and security systems. However, this networked device can also be a target for malicious actors. Fortunately, there are steps you can take to ensure your access control system is secure and that your data is protected against breaches. These include choosing the right system, setting strong passwords, installing updates, and monitoring your network for unauthorized access. With these tips in mind, you can rest assured that your business’s access control system is secure and protected from cyber threats. First, make sure you change the default network passwords and install the latest software versions. Next, use secure protocols where possible and don’t email sensitive data. Finally, implement strong authentication practices, audit your systems regularly, and follow best practices to secure your access control system against hackers.
