In today’s modern world, the enterprise network is changing rapidly, especially when it pertains 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.
An identity-based network access policy and control enforcement system called Cisco identity service engine (ISE) should be considered. The information gathered through certain messages that are passed between the ISE node or profiling and the device, is the basis for the network administrator to centrally control the access policies utilized for wireless, as well as wired endpoints. On a daily basis, the profiling database is updated so that it will be easier to keep up with the greatest and latest devices and to make sure that there are no gaps in the visibility of devices.
In order to provide policy enforcement, as well as security compliance on the device before it is authorized to access the network, identity service engine or ISE makes an identity attachment to the device based on the user, function, and other characteristics. Depending on the results that comes from different variables, an endpoint can only be allowed to access the network if the specific set of rules are applied to the interface where it is connected to, otherwise, the endpoint will be denied or can be given a guest access that are based on the guidelines that your company has. In other words, ISE is an automated policy enforcement engine that deals with the daily task of device and guest on boarding, access list management, switch port VLAN changes for the end-users, and others, in order for the network administrator to focus on other projects and important tasks.
A Simple Plan For Investigating Services
When it comes to the ISE platform, it is a distributed deployment of nodes that are made up of three different types such as monitoring and troubleshooting node (Mnt), policy administration node (PAN), and policy services node (PSN).News For This Month: Networks
