Utm Server

Posted on  by admin

The filtering of HTTPS connections in the UTM's Web Proxy is achieved by preserving the chain of trust between the client and the server with certificate exchanges between the client, the UTM, and the server being accessed. Untangle Network Security Framework. The Untangle Network Security Framework provides IT teams with the ability to ensure protection, monitoring and control for all devices, applications, and events, enforcing a consistent security posture across the entire digital attack surface—putting IT back in control of dispersed networks, hybrid cloud environments, and IoT and mobile devices.

Unified threat management (UTM) is an approach to information security where a single hardware or software installation provides multiple security functions. This contrasts with the traditional method of having point solutions for each security function.[1] UTM simplifies information-security management by providing a single management and reporting point for the security administrator rather than managing multiple products from different vendors.[2][3] UTM appliances have been gaining popularity since 2009, partly because the all-in-one approach simplifies installation, configuration and maintenance.[4] Such a setup saves time, money and people when compared to the management of multiple security systems. Instead of having several single-function appliances, all needing individual familiarity, attention and support, network administrators can centrally administer their security defenses from one computer. Some of the prominent UTM brands are Fortinet, Sophos, WiJungle, SonicWall and Check Point.[5]

UTMs at the minimum should have some converged security features like

  • Intrusion detection service (IDS)
  • Intrusion prevention service (IPS)

Some of the other features commonly found in UTMs are:

  • Gateway anti-virus
  • Application layer (Layer 7) firewall and control
  • Deep packet inspection
  • Web proxy and content filtering
  • Data loss prevention (DLP)
  • Security information and event management (SIEM)
  • Virtual private network (VPN)
  • Network access control
  • Network tarpit
  • Additional security services against Denial of Services (DoS), Distributed Denial of service (DDoS), Zero day, Spyware protection


Although an UTM offers ease of management from a single device, it also introduces a single point of failure within the IT infrastructure. Additionally, the approach of a UTM may go against one of the basic information assurance / security approaches of defense in depth, as a UTM would replace multiple security products, and compromise at the UTM layer will break the entire defense-in-depth approach.[6]
