Simple Network Management Protocol (SNMP) is an Internet Standard protocol of collecting, organizing, and modifying information about managed devices within a network. In other words, SNMP helps system administrators monitor both hardware and software, keeping their information in a convenient, centralized location that saves a great deal of time. SNMP works in a wide variety of devices and programs, including routers, printers, scanners, access panels, and alarm panels. In access control systems, SNMP allows you to keep track of virtually every piece of your business, working to ensure safety across devices and access points.
All of it is monitored from a management station, which is a piece of software. From here, you can perform a variety of tasks, including changing passwords, troubleshooting errors, and sending alerts when a certain device fails. Each facility’s SNMP will be unique, so take care when setting it up; its importance in network security is hard to overstate.
