What Is Nac?Network access control (NAC) is a solution that supports network visibility, access management through policy enforcement on devices and users of a corporate network. Why Do We Need Nac?In organizations now we have exponential growth of mobile devices and the endpoint that accessing their network and then they bring the security risk it very critical to have a solution that provides the visibility, access control, and compliance capabilities that are required to strengthen your network security infrastructure. A NAC system can deny network access to a non-compliant device and place them in the quarantined area or give them only limited access to computing resources thus keeping insecure nodes from infecting the network. What Do You Mean By Network Access?Network access means an endpoint is connecting with our network and tries to access the network resources like accessing printer, computing resources, Internet, Camera, FTP server, Device administration, etc. We have multiple NAC solutions available in the market and one of them is Cisco’s “Identity service Engine (ISE)”. We have two types of Cisco ISE: –
Where can ISE help to achieve the objective of NAC?
ISE is a network security and policy platform, and it has four personas: –
When a network administrator needs to make or change to a security policy on Cisco ISE administrator must access the PAN GUI (Graphical User Interface). PAN, which is the central control center for cisco ISE, all policy is configured and pushed to other ISE Node or personas.
PAN provides the below features: –
In Each ISE deployment, we must have one PSN, and Maximum we can deploy two PSN. One PSN will be primary (Active) and the other will be secondary (standby).
NAD: – NAD stand for Network access device also known as a radius client. NAD is responsible for encapsulation and decapsulation of Radius/ TACACS+ packet as well as encapsulation and decapsulation 802.1x Packet. NAD receives 802.1x packet from the endpoint and decapsulate this packet and pull the information from this packet and again encapsulate this information into RADIUS/TACACS+ packet vice-versa. NAD sends a request to the PSN for Implementing authorization decisions for the resources. Blow devices are known as NAD in networking infrastructure.
Common authorization enforcement mechanisms: • VLAN Assignment/VRF • dACLs & named ACLs MnT: – MnT stands for Monitoring and Troubleshooting Node. The function of this node is to provide the monitoring and troubleshoot function in Cisco ISE deployment. As an endpoint authenticates to ISE an event is created to keep track of the authentication and authorization process. These created events are forwarded to the MnT Node, which then consolidates and processes these events into a legible format. A network administrator requires reports to be created for whatever purpose, such as managerial slides and presentations, access reports, and so on, and this function is also provided by the MnT node. The second function of MnT is troubleshooting. Whatever events are forwarded to MnT success or failure of authentication and authorization process. In Cisco ISE we have detailed event tracking and by this, a network administrator can easily check where the issue is in the authentication or authorization process and troubleshoot this easily. In each ISE deployment at least one MnT node is needed and Maximum we can deploy two MnT nodes in Cisco ISE deployment. One will be the active node and the other will be the Passive node. IPN: – IPN stand for Inline posture node. We can consider IPN as the gatekeeper between a NAD and endpoint. IPN can ensure that an endpoint is adhering to the required security policy before it is given access to the network. The IPN completes the posture assessment of the endpoint by checking Antivirus, Antispyware, OS Patch, label, and another critical parameter, and based upon this check IPN provides endpoint appropriate remediation to get endpoint compliant. Note: – In ISE deployment is not mandatory to deploy an IPN. It is required only when our NAD is capable of holding of CoA(Change to Authorization) request or when an additional posture check is required.

Author Post Views: 414 What is Cisco's network access control solution called?Cisco ISE. Cisco Identity Services Engine (ISE) offers an automated approach to policy enforcement and network access and a foundation for software-defined access and network segmentation in IT and OT environments.
What is NAC used for network access control?NAC is one aspect of network security. It provides visibility into the devices and users trying to access the enterprise network. And it controls who can access the network, including denying access to those users and devices that don't comply with security policies.
What is Forescout NAC solution?Forescout's modern network access control (NAC) gives you the ability to continuously identify all connected things, assess their posture, automate remediation workflows and implement access controls for provisioning least-privilege access.
What is network access control solution?Network access control, or NAC, solutions support network visibility and access management through policy enforcement on devices and users of corporate networks.
Is Cisco ISE a NAC solution?Cisco Systems NAC Solution: Cisco ISE
Cisco Systems have the NAC solution named as Cisco ISE. Cisco ISE stands for Identity Services Engine (ISE) policy server and is RADIUS-based, which enables Cisco to support authentication in heterogeneous network infrastructure environments.
Does Microsoft have a NAC solution?Many Microsoft Intune customers use network access control (NAC) partner solutions to manage access to their on-premises resources.
