TLS is the widely-available protocol that uses PKI (Public Key Infrastructure) keys to encrypt and decrypt data transmissions, and certificates to ensure that only authorized devices can communicate with each other.
With TLS protecting a BACnet network, companies can use a service, such as Qualys, which is a web application and cloud-based service used to detect data breaches and critical misconfigurations across a company’s global hybrid environment. E-banking and other critical applications use such services to identify vulnerabilities including cross-site scripting (XSS) and SQL injection.
