SSL Security Provides an Additional Layer of Security for Terminal Switch Applications

Setting up a secure means to communicate with remote network elements can often be a complicated task; passwords and user accounts must be defined, authentication protocols must be configured, and domain name servers must be set up to recognize terminal switch units. But if the terminal switch unit supports “Self Signed” certificates, this can greatly simplify the process of creating a secure, HTTPS connection with remote network elements.

The reasons why SSL security certificates and server private keys are such an important element in network security are obvious; they provide encrypted communication with remote devices and allow an additional layer authentication for web based communication with remote network elements. But with these advantages, comes the challenge of setting them up properly to fit your application.

In cases where self signed certificates are not supported, signed certificates must be created via an outside security service and then uploaded to the terminal switch in order to verify each user identity. This means that network administrators must first contact an appropriate security service and then set up the domain name server to recognize the terminal switch unit.

When the terminal switch supports the ability to create self signed certificates, this allows network administrators to quickly set up a domain name server to recognize the terminal switch, without the need to refer to an outside security service. This drastically simplifies the process of setting up encrypted SSL communication with remote network devices, yet provides the same level of security that is ordinarily available via a signed certificate.

Terminal switch products provide network administrators with indispensable out of band communication with network elements at remote equipment sites. But as valuable as this out of band communication capability is, if adequate security and authentication are not provided, out of band communication can sometimes prove to be more trouble than it’s worth. That’s why it’s so important to select a terminal switch product that supports both low level security features, a healthy assortment of authentication protocols, and additional security measures like SSL security certificates and server private keys to ensure that access to command functions on remote network devices is properly protected from unauthorized access.
