In these modern times, there is a rapid change in the enterprise network, especially when pertaining to the mobility of employees. The employees’ connection to the enterprise resources nowadays are no longer limited to the desktops that are placed in their workstations because there are already various devices such as tablets, personal laptops, and smart phones that they can use. Having an access to resources regardless of where you are is very advantageous since it can increase the productivity considerably, however, its downside includes the probability of increasing data breaches, as well as security threats due to the fact that you may no longer have control over the security posture of the devices that is trying to access the network. Monitoring and controlling the devices that tries to access the network is a big task already, which means that it even becomes more challenging if the need for more access will occur.
With this is mind, it is wiser to use the Cisco identity service engine (ISE) which is an identity-based network that is capable of accessing the control and policy of enforcement systems. 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. In order to keep up with the greatest and the latest devices to ensure that there are no gaps in the visibility of devices, the profiling database is updated regularly.
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.
