Enhancing Security With Nexus Iq Scanning Open Source Libraries In Spring Boot

Jun 14, 2024

In today’s software development landscape, open source libraries are essential for speeding up development. However, they also introduce potential security vulnerabilities. Nexus IQ is a powerful tool that helps you manage and mitigate risks associated with using open source libraries. This blog post will demonstrate how to integrate Nexus IQ with a simple Spring Boot application using Maven profiles, enabling you to perform security scans both locally and in a CI/CD pipeline.

Prerequisites

Before we start, ensure you have the following:

A basic understanding of Maven and Spring Boot.
Nexus IQ server up and running (local or hosted).
Maven installed.
A simple Spring Boot application.

Setting Up Nexus IQ

Download and Install Nexus IQ:
- Follow the instructions on the Nexus IQ download page to install and start Nexus IQ.
Create an Application in Nexus IQ:
- Log in to your Nexus IQ instance.
- Create a new application and generate the necessary credentials.

Configuring Maven for Nexus IQ

Add Nexus IQ Plugin to pom.xml:

<project>
    ...
    <build>
        <plugins>
            ...
            <plugin>
                <groupId>org.sonatype.plugins</groupId>
                <artifactId>nexus-clm-maven-plugin</artifactId>
                <version>2.47.14-01</version>
            </plugin>
            ...
        </plugins>
    </build>
    ...
</project>

Define Maven Profiles: We’ll create two Maven profiles—one for local scans and one for CI/CD.

<project>
    ...
    <profiles>
        <profile>
            <id>nexus-iq-local</id>
            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>
            <properties>
                <nexus.iq.server.url>http://localhost:8070</nexus.iq.server.url>
                <nexus.iq.application.publicId>your_application_public_id</nexus.iq.application.publicId>
                <nexus.iq.username>your_local_nexus_iq_username</nexus.iq.username>
                <nexus.iq.password>your_local_nexus_iq_password</nexus.iq.password>
            </properties>
        </profile>

        <profile>
            <id>nexus-iq-ci</id>
            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>
            <properties>
                <nexus.iq.server.url>http://your-ci-nexus-iq-url</nexus.iq.server.url>
                <nexus.iq.application.publicId>your_application_public_id</nexus.iq.application.publicId>
                <nexus.iq.username>your_ci_nexus_iq_username</nexus.iq.username>
                <nexus.iq.password>your_ci_nexus_iq_password</nexus.iq.password>
            </properties>
        </profile>
    </profiles>
    ...
</project>

Externalizing Credentials

Instead of hardcoding credentials in pom.xml, use environment variables or a properties file. Here’s how:

Using Environment Variables:

Set Environment Variables:

export NEXUS_IQ_SERVER_URL=http://your-ci-nexus-iq-url
export NEXUS_IQ_APPLICATION_PUBLIC_ID=your_application_public_id
export NEXUS_IQ_USERNAME=your_nexus_iq_username
export NEXUS_IQ_PASSWORD=your_nexus_iq_password

Reference Environment Variables in pom.xml:

<project>
    ...
    <profiles>
        <profile>
            <id>nexus-iq-local</id>
            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>
            <properties>
                <nexus.iq.server.url>${env.NEXUS_IQ_SERVER_URL}</nexus.iq.server.url>
                <nexus.iq.application.publicId>${env.NEXUS_IQ_APPLICATION_PUBLIC_ID}</nexus.iq.application.publicId>
                <nexus.iq.username>${env.NEXUS_IQ_USERNAME}</nexus.iq.username>
                <nexus.iq.password>${env.NEXUS_IQ_PASSWORD}</nexus.iq.password>
            </properties>
        </profile>

        <profile>
            <id>nexus-iq-ci</id>
            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>
            <properties>
                <nexus.iq.server.url>${env.NEXUS_IQ_SERVER_URL}</nexus.iq.server.url>
                <nexus.iq.application.publicId>${env.NEXUS_IQ_APPLICATION_PUBLIC_ID}</nexus.iq.application.publicId>
                <nexus.iq.username>${env.NEXUS_IQ_USERNAME}</nexus.iq.username>
                <nexus.iq.password>${env.NEXUS_IQ_PASSWORD}</nexus.iq.password>
            </properties>
        </profile>
    </profiles>
    ...
</project>

Running Nexus IQ Analysis Locally

To run the Nexus IQ analysis locally, use the following command:

mvn clean verify org.sonatype.plugins:nexus-clm-maven-plugin:2.47.14-01:scan -Pnexus-iq-local

Integrating Nexus IQ in CI/CD Pipeline

For CI/CD, you’ll configure your pipeline to trigger the Nexus IQ scan using the nexus-iq-ci profile. Here’s an example using GitHub Actions:

GitHub Actions Workflow (.github/workflows/ci.yml):

name: CI

on:
  push:
    branches:
      - main
  pull_request:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout code
      uses: actions/checkout@v2

    - name: Set up JDK 11
      uses: actions/setup-java@v2
      with:
        java-version: '11'

    - name: Build with Maven
      run: mvn clean verify

    - name: Nexus IQ Scan
      env:
        NEXUS_IQ_SERVER_URL: $
        NEXUS_IQ_APPLICATION_PUBLIC_ID: $
        NEXUS_IQ_USERNAME: $
        NEXUS_IQ_PASSWORD: $
      run: mvn org.sonatype.plugins:nexus-clm-maven-plugin:2.47.14-01:scan -Pnexus-iq-ci

Conclusion

Integrating Nexus IQ with your Spring Boot application using Maven profiles allows you to proactively manage and mitigate security risks associated with open source libraries. By following the steps outlined in this post, you can set up a robust system for continuous security monitoring both locally and in your CI/CD pipeline.
