How Can You Be Sure Your Remote Connectivity Solution is Secure?
You’ve likely heard of some of the benefits of a reliable remote connectivity solution by now: from decreased travel time and costs to predictive maintenance, the benefits are there in a well-designed solution.
But maintaining secure connections and access methods is paramount. It can be daunting to determine the security needed for your operation, but here are a few aspects you should be aware of when planning your remote connectivity strategy:
- If you’re considering a platform that utilizes the remote user’s PC, it’s best to opt for one that does not require software patches. This has been a top avenue for hackers. Instead, look for a program that’s updated for you, with no user-installed software. This will also save your workers time since they will not have to handle software updates.
- You may need to grant access to your plant equipment to an outside vendor – but you don’t need to give them access to every network in your facility. Consider a solution that lets you bypass a guest VPN option – one option is a gateway that will let the outside worker access just the portion of your operation they need to see.
- Two-factor authentication is used by many services to ensure security, but not all methods are at the same security level. Some companies opt for SMS-based authentication, which NIST has cautioned against. A token-based approach is a more robust verification method.
