What is UTM and its function
What is Unified Threat Management (UTM)?
Unified Threat Management (UTM) is an information security term that describes a single security solution and usually a single security appliance that provides multiple security functions at a single point within a network. A UTM device typically provides anti-virus, anti-spyware, anti-spam, network firewall, intrusion detection and monitoring, content filtering, and data leakage prevention. Some devices also have services such as remote routing, network address translation (NAT), and virtual private network (VPN) support. The attraction of these solutions is their simplicity. Organizations that previously used a different vendor or device for each of the security functions can now get everything from a single vendor, have it serviced by an IT team or segment, and run from one console.
This is how UTM devices block a computer virus or a combination of several threats
Unified Threat Management devices are becoming increasingly popular in the industry due to the emergence of complex threats - combinations of malware and attacks that target different parts of the network at the same time.
Defense against such attacks is less effective if different devices and providers are used for each security function, as the individual components also have to be managed and updated separately in order to always be up to date to protect against the latest forms of malware and cybercrime. UTM solutions create a central defense position with a comprehensive console and thus simplify the handling of a wide range of threats.
UTM solutions are effective for certain problems in the area of network security, but they also have disadvantages, in particular that the UTM appliance is both the central defensive position and the central weak point. For this reason, many companies choose to add a second, software-based line of defense to their UTM device to ward off malware that has overcome the UTM firewall.
