Hello everyone my name is vijay kumar Devireddy and i am glad to have you back on my episode 62 today we're going to discuss about Unified threat management,the unified threat management or UTM system is a newer concept that was introduced in the last five to 10 years.Basically, security professionals realized as I'm sure you're realizing now too,that relying on a single firewall is not enough to protect our networks,and so a UTM was created, now a unified threat management system is a combination of network security devices and technologies that are added to a network to better protect it.Simply put a UTM is a single device that combines many other devices and technologies into it.For example your UTM might include a firewall,a network intrusion detection system,or a network intrusion prevention system,a content filter or a proxy, an antivirus or anti-malware gateway, a data loss prevention system,and maybe even a site to site VPN if you have the need.Now these devices are designed to make it easier for a security administrator to use them.And instead of relying on a command line interface,with all the tech space commands,they get a graphical user interface instead.It allows them to make policies, rules, and signatures,that makes it much easier and much quicker to use.Now UTM's provide a singular package with multiple protections.And they are essentially a defense in depth strategy within a single device or system.Because of this often these devices will replace your firewall, and it's usually placed as the outer most device in your local area network.To provide its' perimeter defense and its' protections.You may have also heard the term, Next Gen Firewall,or Next Generation Firewall, also known as NGFW.If you've heard this term, it's because it's being used in the industry instead of using the term UTM or unified threat management.These are those all in one security devices and that's all a Next Generation Firewall is.This is a marketing ploy because people weren't understanding the UTM concept,but they understood firewalls,and so calling it a Next Generation Firewall helped them increase sales.
