#Utm network upgrade
Ultimately, t his forces an appliance upgrade with all of the additional costs and complexity involved. As enterprises enable more security functions and as traffic levels grow, the appliance s require more processing power. The concept of UTM is good -the execution, not so much. This new all-in-one security device is what became known as the UTM. These functions could all be separate appliances, or they could all be brought together into a single converged appliance. They also want malware inspection, intrusion detection and prevention, content filtering, and other security measures. While firewalls are essential, companies need more than just a firewall in their security quiver. UTM s Converg e Security into One Appliance
This led to the development of next generation firewalls ( NGFWs ) that look into the application layer to determin e whether or not a flow is malicious. But as applications and networking evolved, firewalls needed to look beyond port 80 to make a determination whether or not a packet flow was malicious.Īs the industry started to adopt applications and services that shared common TCP ports, simply looking at the source o r destination address and the TCP information wasn’t sufficient to detect malicious traffic. Traditionally, port 80 of the firewall bore extra scrutiny because this is where web traffic came in. All traffic passed through the firewall for basic inspection of security policies based on network information such as the type of protocol or the source/destination addresses. It was a physical appliance installed at a location such as a datacenter or a branch office. Firewalls Evolve Over the Yearsīefore the UTM, there was the basic firewall. How can you t ake the UTM ’s benefits and avoid the scalability problem? Let’s take a look to find out what ’s beyond the UTM and the future of network security. In reality, though, UTMs often became headaches in the making, putting IT on a vicious and costly life cycle of appliance upgrades. In theory, Universal Threat Management (UTM) platforms should have long ago promote d efficiency : collapsing many security features into a single appliance.
