Implementing Advanced Security Policies in Aruba AOS8

Introduction

In today’s rapidly evolving digital landscape, network security has become critically important. As cyber threats grow in complexity and sophistication, it becomes imperative for organizations to employ robust security measures to protect their network infrastructures effectively. Aruba AOS8, a powerful and versatile network operating system, provides a comprehensive suite of advanced security features that can be tailored to safeguard network integrity. This lesson will guide you through the process of implementing advanced security policies within Aruba AOS8. We will focus on configuring role-based access control, setting up network access policies, and integrating essential security protocols.

Understanding Aruba AOS8

Aruba AOS8 is engineered to enhance the performance, reliability, and security of wireless networks. It offers a centralized architecture, facilitating scalable and efficient management of network resources. The security features embedded in AOS8 are designed to cater to the ever-changing needs of enterprises, enabling secure access and the protection of sensitive data from unauthorized access and potential breaches.

Configuring Role-Based Access Control (RBAC)

Role-Based Access Control (RBAC) is a fundamental aspect of network security that limits network access based on predefined user roles. This ensures that users only have access to the resources necessary for their roles. In Aruba AOS8, configuring RBAC involves several key steps:

1. Define User Roles: Begin by identifying and defining the roles within your organization, such as administrator, guest, and employee. Determine the specific access levels and permissions required for each role.

2. Create User Roles in AOS8: Access the Aruba Mobility Master (MM) dashboard, navigate to the “Configuration” tab, and select “Roles.” Click “Add” to create new roles, specifying the permissions and restrictions applicable to each role.

3. Assign Policies to Roles: For each user role, define the access policies that outline permitted and denied actions. Use the “Policy” tab to configure policies, such as allowing access to specific VLANs or blocking certain protocols.

4. Apply Roles to Users: Assign the defined roles to users or groups within your network by leveraging the RADIUS server or internal databases to map user credentials to their respective roles.

Setting Up Network Access Policies

Network Access Policies (NAP) dictate the conditions under which users can access the network, playing a crucial role in maintaining security and ensuring compliance with organizational standards. The following steps outline how to establish NAPs:

1. Define Access Criteria: Determine criteria for network access, including device type, location, and time of access.

2. Configure Authentication Methods: Utilize Aruba AOS8’s support for various authentication methods, such as 802.1X, MAC authentication, and captive portal. If necessary, set up an external authentication server, such as RADIUS or LDAP.
