Mastering Aruba PEC: A Comprehensive Guide to Secure Mobile Device Enrollment
In today’s interconnected world, secure and seamless mobile device enrollment is paramount for organizations of all sizes. Aruba’s Policy Enforcement Controller (PEC), often integrated with ClearPass Policy Manager, plays a crucial role in ensuring that only compliant and authenticated devices gain access to the network. The Aruba PEC app simplifies and streamlines the enrollment process, providing a user-friendly interface for employees and guests alike. This comprehensive guide delves into the workings of the Aruba PEC app, providing detailed steps and instructions to help you master secure mobile device enrollment.
## What is Aruba Policy Enforcement Controller (PEC)?
Before diving into the app itself, it’s essential to understand the function of the Policy Enforcement Controller. PEC is a key component of Aruba’s network security architecture. It sits between the wireless (or wired) network and the user’s device, acting as a gatekeeper. Its primary functions include:
* **Authentication:** Verifying the identity of the user attempting to connect to the network.
* **Authorization:** Determining the level of network access granted to the user based on their role and device compliance.
* **Posture Assessment:** Evaluating the security posture of the device, ensuring it meets the organization’s defined security policies (e.g., up-to-date antivirus, OS patching, device encryption).
* **Remediation:** Guiding non-compliant devices through a process of remediation, helping them meet the required security standards before granting full network access.
The PEC app acts as the user interface for this process, guiding users through authentication, posture assessment, and remediation steps on their mobile devices. Often integrated tightly with ClearPass Policy Manager, PEC leverages the central policy engine for consistent enforcement across the network.

## Prerequisites for Using the Aruba PEC App
Before using the Aruba PEC app, ensure the following prerequisites are met:
1. **Aruba Network Infrastructure:** Your organization must have an Aruba network infrastructure with a properly configured Policy Enforcement Controller (PEC) and, ideally, ClearPass Policy Manager.
2. **Network Configuration:** The network must be configured to redirect users attempting to access the internet to the PEC portal when they are not yet authenticated or compliant.
3. **PEC App Installation:** The Aruba PEC app must be installed on the user’s mobile device. It’s available for both iOS and Android devices from their respective app stores (Apple App Store and Google Play Store).
4. **Internet Connectivity:** The device must have internet connectivity to download the app, communicate with the PEC, and potentially download necessary security software.
5. **User Credentials:** Users must have valid credentials to authenticate to the network (e.g., username/password, digital certificate).
6. **Device Compatibility:** Ensure the mobile device meets the minimum operating system requirements for the Aruba PEC app.
## Step-by-Step Instructions for Using the Aruba PEC App
The following section provides detailed step-by-step instructions on how to use the Aruba PEC app to enroll a mobile device on the network.
**Step 1: Connecting to the Network**
1. **Connect to the Wi-Fi Network:** On your mobile device, connect to the designated Wi-Fi network for guest or employee access. This network is typically configured to redirect users to the PEC portal.
2. **Automatic Redirection:** After connecting to the Wi-Fi network, open a web browser (e.g., Chrome, Safari). You should be automatically redirected to the Aruba PEC portal or a captive portal that prompts you to download the app.
**Step 2: Downloading and Installing the Aruba PEC App**
1. **Download the App:** If you are redirected to a captive portal, follow the instructions to download the Aruba PEC app from the Apple App Store (iOS) or Google Play Store (Android). You may need to scan a QR code or click on a direct link.
2. **Install the App:** Once the app is downloaded, install it on your mobile device. You may need to grant the app necessary permissions during installation, such as access to the camera (for QR code scanning) and network access.
**Step 3: Launching the Aruba PEC App and Initial Configuration**
1. **Launch the App:** After installation, launch the Aruba PEC app. You might be presented with a welcome screen or terms of service agreement. Accept the terms and conditions to proceed.
2. **Server Configuration (if required):** In some cases, you may need to manually configure the app with the address of the PEC server. This information is typically provided by your IT administrator. Look for a settings or configuration option within the app to enter the server address. If the app automatically detects the PEC server, this step may be skipped.
**Step 4: Authentication**
1. **Authentication Method Selection:** The app will present you with available authentication methods. Common options include:
* **Username/Password:** Enter your network username and password.
* **Digital Certificate:** Select a digital certificate if your organization uses certificate-based authentication. The app will guide you through the certificate selection process.
* **Multi-Factor Authentication (MFA):** If MFA is enabled, you may be prompted to enter a code generated by an authenticator app or receive a code via SMS.
2. **Enter Credentials:** Enter your credentials and follow the on-screen instructions to complete the authentication process. The app will communicate with the PEC server to verify your identity.
3. **Successful Authentication:** Upon successful authentication, the app will display a confirmation message and proceed to the posture assessment phase.
**Step 5: Posture Assessment**
1. **Automated Security Checks:** The Aruba PEC app will automatically perform a series of security checks to assess the device’s compliance with the organization’s security policies. These checks may include:
* **Operating System Version:** Verifying that the device is running a supported and up-to-date operating system.
* **Antivirus Software:** Checking for the presence and status of antivirus software.
* **Device Encryption:** Verifying that the device is encrypted.
* **Firewall Status:** Checking if the device’s firewall is enabled.
* **Application Compliance:** Checking for the presence of specific applications or the absence of prohibited applications.
* **OS Patching:** Ensuring the latest security patches are installed.
2. **Progress Monitoring:** The app will display a progress bar or a list of checks being performed. This allows you to monitor the posture assessment process.
3. **Posture Assessment Results:** After completing the security checks, the app will display the results. It will indicate whether the device is compliant or if any issues need to be addressed.
**Step 6: Remediation (if required)**
1. **Identify Non-Compliant Issues:** If the posture assessment identifies any security issues, the app will display a list of non-compliant items.
2. **Remediation Instructions:** For each non-compliant item, the app will provide detailed instructions on how to remediate the issue. This may include:
* **Updating the Operating System:** Instructions on how to update the device’s operating system.
* **Installing Antivirus Software:** Links to download and install approved antivirus software.
* **Enabling Device Encryption:** Instructions on how to enable device encryption.
* **Enabling Firewall:** Instructions on how to enable the device’s firewall.
* **Installing Required Applications:** Links to download and install required applications.
3. **Follow Remediation Steps:** Carefully follow the instructions provided by the app to address each non-compliant issue. This may involve downloading and installing software, configuring settings, or updating the operating system.
4. **Re-run Posture Assessment:** After addressing the non-compliant issues, re-run the posture assessment within the app. This will verify that the issues have been resolved and that the device is now compliant.
**Step 7: Accessing the Network**
1. **Compliance Confirmation:** Once the device passes the posture assessment and is deemed compliant, the app will display a confirmation message.
2. **Network Access Granted:** The app will automatically grant the device access to the network based on your organization’s defined access policies. You can now browse the internet, access internal resources, and use network applications.
3. **Persistent Connection (Optional):** Depending on the network configuration, the app may maintain a persistent connection to the network, ensuring continuous compliance monitoring. Some networks might require periodic re-authentication or posture reassessment.
