What You Need to Know About Identity Service Engines The enterprise network these days are already changing quickly , especially with regards to employee mobility. The technological advancements have helped employees to gain access in enterprise resources through the use of various devices such as smartphones, tablets, and personal laptops. Without a doubt, the productivity of your company will be increased if your employees will be able to access their needed resources from anywhere, but the thing is, it can also increase the chance of having data breaches and threats in security because the devices that are accessing the network will be hard to control. With that being said, it will be a huge and difficult task to keep track of all the devices that are accessing the network, and if ever there is a need for more access, the more it becomes unsustainable to manage. An identity-based network access policy and control enforcement system called Cisco identity service engine (ISE) should be considered. By using an identity service engine (ISE), the network administrator that you have assigned will be able to centrally control the access policies used for wired and wireless endpoints depending on the information gathered through some messages that are passed between the device and the ISE node, which is also regarded as profiling. Moreover, ISE also updates the profiling database daily to keep up with the greatest, as well as the latest devices so that there will be no gaps in device visibility. Usually, identity service engine or ISE makes an identity attachment to a device based upon the function, user, and other features so that it can provide security compliance and policy enforcement prior to authorizing the device to access the network. An endpoint will only be allowed to access the network if the results from various variables matches with the specific rules where the interface is connected, or else, a guest access will be provided based on your company’s guidelines or there will be a complete denial of access. To put it accurately, a network administrator can focus his or her attention on doing some other important project or tasks since the ISE will be the one to take care of day to day tasks such as access list management, guest and device onboarding, changes in switch port VLAN for end-users, and many more.
