Download Secure File Task Azure Devops
Yasmine Cafasso
The primary tasks for administrators to secure Azure DevOps are to assign access levels, set permissions, assign security roles, and set policies. Development leads and pipeline administrators should become familiar with setting permissions and policies on repositories, branches, and pipeline resources.
creating an sdk that uses AWS DynamoDb in .NET 4.7.2. In my test project, I have an app.config file that references a secrets.confg file that stores my AWS keys. The secrets config is not included in any commits, for obvious reasons. However, I've uploaded secrets.config to my Library in DevOps as a "secure file". I also have a "download config file" task in the build process that downloads secrets.config to Agent.Temporary
These capabilities exist in the DevOps Kit PowerShell module (AzSK) as cmdlets viz. 'Get-AzSKARMTemplateSecurityStatus' and 'Get-AzSKAzureServiceSecurityStatus' respectively. These cmdlets can be run manually by developers on their individual machines. However, if configured in the CICD pipeline as pre-deploy/release tasks, teams can ensure that insecurely configured resources are not created via pipeline-based deployments (via the ARM Template Checker task) and security of deployed/existing resources does not regress (via the SVTs task). In this way, the extension provides a way to inject pre- and post-deployment secure configuration checks for cloud resources inside the CICD pipeline.
I declared connection string on the pipeline variables page as secure but in the pipeline I cannot obtain the value. I have already read related page in docs but it doesn't provide an example when I want to use a value in a task. -us/azure/devops/pipelines/process/variables?view=azure-devops&tabs=yaml%2Cbatch#secret-variables
As a result of the above, PowerShell tasks have had a much lighter security screening in this report. It doesn't necessarily mean PowerShell tasks are better or more secure, it simply means their state is mostly unknown.
Pipeline tasks generally contain a very small amount of custom code. For example, the task to publish an Azure DevOps Extension contains 41KB of custom code against 8.4MB of dependencies. These 8.4MB of dependencies are frozen at the time the extension is published, so the responsibility to provide any security updates falls to the extension author. Every version of the azure-pipelines-task-lib, except the latest v3 and v4 have vulnerable dependencies, so it's important for authors to regularly update their extension.
Of the Node based tasks, there is a total of 17894 vulnerabilities introduced through dependencies. 7088 are introduced by old versions of the azure-pipelines-task-lib.
The task-lib version is a good indication of other vulnerabilities. Below is a breakdown of all versions of the azure-pipelines-task-lib (and predecessors) in use by all tasks in the marketplace. As you can see only 192 tasks are using the most recent versions:
You'll find the docs are littered with "support was added in 2.122.0" and "you need to use 2.125.0 or above version agent".
Some tasks query for this agent version in code and emit a warning if less secure behavior is used because the task is running on an old agent.
Most tasks turn off certificate checks for the whole task's execution using NODE_TLS_REJECT_UNAUTHORIZED=0. If the task itself or any of its dependencies try to contact an external resource, this resource can now be spoofed. At least an agent version check to tell the operator to upgrade their agent will help administrators to enable these new features (but fails to consider the Azure DevOps Server version might not even ship with that agent version). This extension also uses a property to control this behavior and defaults to a secure configuration.
For me, this scan took all of 5 seconds to run against my demo container liamgu/azuredevopscontainersdemo:74 image and the results were great. It scans the image itself and whatever is on the image. This particular image is based on httpd:latest.
In my previous article,Azure DevOps CI/CD using GitHub Repo and VisualStudio Azure SQL Database Project, I demonstrated how to deploy an Azure SQLDatabase from Visual Studio using Azure DevOps using the Azure SQL Database deploymentrelease task. However, with this process, the SQL Database Username and Passwordwas exposed in the DevOps Azure Pipeline. This can be a concern for a number ofreasons including security, compliance, audits and more. How can we secure secretsin Azure DevOps pipelines?
Azure DevOps tasks are the building blocks for defining automation in pipelines.Tasks are packaged scripts or procedures that have been abstracted with a set ofinputs. Often times, these inputs contain sensitive credentials and secrets thatneed to be appropriately secured. There are a few options for securing secrets inAzureDevOps pipelines including pipeline variables, variable groups, and Azure KeyVault tasks. In this article, I will demonstrate how to implement these options.As a pre-requisite, ensure that you have completed the steps outlined in my previousarticle,Azure DevOps CI/CD using GitHubRepo and Visual Studio Azure SQL Database Project.
