Who is on Your Network?

May 1, 2023 Jason Dell

In today's digital landscape, the security of your network is more important than ever. With the rise of the hybrid workforce, cloud services, and mobile devices, there are more access points to your network than ever before. That's why it's crucial to know what's on your network and who has access to your network. This is where identity services come into play, and Cisco Identity Services Engine (ISE) is the leading solution in the market.

What Are Identity Services?

Identity services are a set of tools that allow you to control access to your network by authenticating and authorizing users and devices. Without them, anyone or anything could potentially access your network, including hackers, malicious insiders, and unauthorized devices. Identity services help you ensure that only authorized users and devices can access your network. This helps you protect your data, applications, and other resources.

Identity services give you visibility into who and what is accessing your network and what they're doing. This information can help you detect and respond to threats quickly.

Identity services help you enforce security policies and ensure compliance with regulations.

What Is Cisco Identity Services Engine?

Cisco Identity Services Engine (ISE) is a leading identity services solution that provides authentication, authorization, and accounting (AAA) services for network access. It allows you to control access to your network based on user identity, device type, location, and other factors. It also provides visibility into who is accessing your network and what they're doing.

ISE supports a range of authentication methods, including username/password, certificate-based authentication, MAC address bypass, and authentication by device profile.

Cisco ISE is a powerful identity services solution that can be used to enhance security and streamline operations in a variety of use cases, such as:

  1. Network Access Control (NAC): ISE can be used to enforce access policies and control network access for users and devices, ensuring that only authorized users and devices are granted access to the network.
  2. Device Onboarding: ISE can automate the process of onboarding new devices onto the network, making it easy to deploy new devices while maintaining security and compliance.
  3. Guest Access: ISE can be used to provide secure guest access to the network, ensuring that guests are authenticated and authorized before being granted access.
  4. Bring Your Own Device (BYOD): ISE can be used to securely onboard and manage personal devices on the network, providing a seamless and secure BYOD experience for employees.
  5. Security Operations: ISE can provide real-time visibility and control over users and devices on the network, helping security teams quickly detect and respond to security threats.

These are just a few of the many use cases for Cisco ISE.

Credential Misuse

According to a recent industry report, stolen credentials were the most common attack method in data breaches, with 61% of breaches involving the use of stolen or weak passwords. This same report also found that the use of multi-factor authentication can significantly reduce the risk of a successful attack. In fact, 85% of data breaches could have been prevented if multi-factor authentication had been in place.

What is Cisco Duo?

Cisco Duo is a powerful multi-factor authentication solution that can significantly enhance the security of your network. Duo provides several additional security features that ensure only authorized users are granted access to your network. These include:

  1. Adaptive Authentication: Duo uses contextual information such as location, device, and behavior to determine the level of authentication required. This means that if a user is trying to access the network from a trusted location or device, they may only need to provide a single factor of authentication. However, if a user is attempting to access the network from an unknown device or location, Duo can require additional factors of authentication, such as a push notification or biometric scan.
  2. Strong Authentication: Duo provides a range of authentication methods that are more secure than traditional passwords. These include push notifications, biometric scans, one-time passcodes, and more. By requiring these additional factors of authentication, Duo ensures that only authorized users can access the network.
  3. Easy Administration: Duo provides a centralized administration console that makes it easy to manage users and devices. You can quickly provision new users, revoke access, and view detailed reports on user activity.
  4. Flexible Deployment: Duo can be deployed in several ways, including as a cloud-based service, on-premises, or as a hybrid deployment. This flexibility allows you to choose the deployment model that best suits your organization's needs.

Cisco ISE and Cisco Duo: Better Together

By using Cisco Duo with Cisco ISE, you can create a comprehensive identity services and multi-factor authentication solution that provides advanced security features, ease of administration, and flexible deployment options.

Cisco Identity Services Engine and Cisco Duo are not only leading solutions for identity services and multi-factor authentication, but they are also part of the larger Cisco Security Ecosystem. This ecosystem consists of a broad range of security solutions that work together to provide comprehensive security for your network.


Identity services with multi-factor authentication are essential for network security, and Cisco Identity Services Engine and Cisco Duo are leading solutions in the market.
