Role of User Identity
Identity-based UTM appliances are the next-generation security solutions offering comprehensive protection against emerging blended threats. While simple UTMs identify only IP addresses in the network, identity-based UTMs provide discrete identity information of each user in the network along with network log data. They allow creation of identity-based network access policies for individual users, delivering complete visibility and control on the network activities. The identity-based feature of such UTMs runs across the entire feature set, enabling enterprises to identify patterns of behavior by specific users or groups that can signify misuse, unauthorized intrusions, or malicious attacks from inside or outside the enterprise.
The strength of UTM technology is that it is designed to offer comprehensive security while keeping security an easy-to-manage affair. Enterprises get complete network information in hand to take proactive action against network threats in case of inappropriate or suspicious user behavior in the network. As identity-based UTMs do not depend on IP addresses, they provide comprehensive protection even in dynamic IP environments such as DHCP and WI-Fi and especially in a scenario where multiple users share the same computer.

“In today’s world parents find themselves at the mercy of a society which imposes pressures and priorities that allow neither time nor place for meaningful activities and relations between children and adults, which downgrade the role of parents and the functions of parenthood, and which prevent the parent from doing things he wants to do as a guide, friend, and companion to his children.”

—Betty Friedan (20th century)
“A worker may be the hammer’s master, but the hammer still prevails. A tool knows exactly how it is meant to be handled, while the user of the tool can only have an approximate idea.”
—Milan Kundera (b. 1929)
“Though your views are in straight antagonism to theirs, assume an identity of sentiment, assume that you are saying precisely that which all think, and in the flow of wit and love roll out your paradoxes in solid column, with not the infirmity of a doubt.”
