OpenVPN is a popular open-source VPN solution that allows secure, remote access to your infrastructure. When combined with AWS Identity and Access Management (IAM), you can enable granular control over which users or services can access your OpenVPN server. This setup can implement Role-Based Access Control (RBAC), which offers a fine-tuned security model to enforce different access levels based on user roles. This article will guide you through the process of integrating OpenVPN with AWS IAM to manage user access based on roles.PrerequisitesBefore you begin, ensure you have the following components in place:OpenVPN server installed and configured on an AWS EC2 instance.AWS IAM roles and policies set up for access control.Access to an AWS account with necessary permissions to modify IAM roles and policies.A basic understanding of OpenVPN and AWS IAM concepts.Setting Up OpenVPN on AWS EC2To begin with, you’ll need to set up OpenVPN on an EC2 instance. Use the Amazon Linux 2 AMI or a preferred Linux distribution.Start by launching an EC2 instance and SSH-ing into the server. Then install OpenVPN and the necessary dependencies:sudo yum update -ysudo yum install openvpn -yNext, configure the OpenVPN server according to your network requirements, including generating server certificates and setting up IP forwarding:sudo sysctl -w net.ipv4.ip_forward=1Integrating AWS IAM with OpenVPNThe goal is to use AWS IAM roles to authenticate and authorize OpenVPN users. The integration involves using the AWS IAM service to control access permissions. You will configure OpenVPN to validate users via IAM roles that define specific access levels.1. Creating IAM RolesIn the AWS Management Console, create IAM roles that correspond to different access levels for OpenVPN users. Each role will have policies that define what AWS resources can be accessed by users assigned to that role.aws iam create-role --role-name OpenVPN-Role --assume-role-policy-document file://trust-policy.jsonDefine a trust policy that allows OpenVPN users to assume the role. The trust policy file might look like this:{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "ec2.amazonaws.com" }, "Action": "sts:AssumeRole" } ]}Attach the appropriate policies to the role, ensuring that users can access only the resources they need:aws iam attach-role-policy --role-name OpenVPN-Role --policy-arn arn:aws:iam::aws:policy/AmazonS3ReadOnlyAccess2. Configuring OpenVPN to Use AWS IAM RolesAfter creating the roles, configure OpenVPN to authenticate users using IAM credentials. You can use AWS CLI or SDKs to assume IAM roles dynamically during the VPN connection process.For example, in the OpenVPN server configuration file, use the following settings to authenticate users via

The AWS IAM service:plugin /usr/lib/openvpn/plugins/openvpn-auth-aws.soauth-user-pass-verify /usr/local/bin/aws-iam-auth.sh via-envThe script aws-iam-auth.sh will verify the IAM credentials. Below is an example script that uses AWS CLI to assume a role:USER=$1PASSWORD=$2aws sts get-session-token --serial-number arn:aws:iam::123456789012:mfa/$USER --token-code $PASSWORD --duration-seconds 3600This script validates the user by using multi-factor authentication (MFA) and retrieves temporary session credentials via AWS Security Token Service (STS). These credentials will allow OpenVPN to verify user roles and provide appropriate access.Configuring Role-Based Access ControlWith IAM roles now integrated into the OpenVPN authentication process, the next step is setting up Role-Based Access Control (RBAC). You can configure different access rights for different users based on their IAM roles.1. Creating Access Control PoliciesDefine specific access control policies that correspond to user roles. For example, you might want a role that gives access to a specific subnet or restricts access to only certain services. Use AWS IAM policies for fine-grained access control.aws iam create-policy --policy-name OpenVPN-Admin-Policy --policy-document file://admin-policy.jsonThe admin-policy.json might look like this:{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "ec2:DescribeInstances", "Resource": "*" } ]}2. Assigning Roles to OpenVPN UsersTo assign the roles to specific OpenVPN users, create a mapping between the OpenVPN certificate and the IAM role. This can be done through a script that maps certificates to roles. The script could look like this:USER_CERT=$1if [[ "$USER_CERT" == "user1" ]]; then echo "arn:aws:iam::123456789012:role/OpenVPN-Admin-Role"else echo "arn:aws:iam::123456789012:role/OpenVPN-ReadOnly-Role"fiThis script assigns a role based on the user’s certificate, which helps automate the process of granting access based on the role.We earn commissions using affiliate links.
