AI Application Security Posture Management

Question

Pulumi · Accepted Answer

When it comes to managing the security posture of an application using infrastructure as code like Pulumi, there are various resources and services provided by cloud providers to enhance your application's security. These can include threat detection, web application firewall configurations, security groups, and access control.

In the case of Azure, for instance, you could use `AdvancedThreatProtection` to safeguard your data from threats, and `AdaptiveApplicationControls` which provide AI-based application control to prevent unapproved applications from running on your virtual machines.

For Akamai, you might employ services like `AppSecConfiguration` to oversee the application's security settings and define rules and protections with `AppSecSecurityPolicy` and `AppSecActivations`.

Below is a program written in Python that uses Pulumi to define application security resources in Azure. This program will create an instance of Azure's `AdvancedThreatProtection` and `ApplicationSecurityGroup`. This is just a starting point and can be extended based on application-specific needs like which resources to monitor with ATP or which virtual machines to include in the ASG.

Before diving into the code, let's discuss the chosen resources and their functions:

- `AdvancedThreatProtection` is an Azure resource that enables you to set up advanced threat detection capabilities on your cloud resources. It helps protect against a multitude of threats by analyzing a massive amount of signals and using machine learning to quickly detect and mitigate threats.

- `ApplicationSecurityGroup` is a resource in Azure that helps you manage access to networked resources. It allows you to group together VMs and define network security policies based on those groups. This is a way to decouple your security rules from your virtual machine's IP addresses, providing more granularity in your security posture management.

Here's how you might define these resources in a Pulumi program:

```python
import pulumi
import pulumi_azure_native.security as security
import pulumi_azure_native.network as network

# This creates an instance of Advanced Threat Protection for the specified resource.
advanced_threat_protection = security.AdvancedThreatProtection(
    setting_name="current",  # The setting name, "current" is typically used
    resource_id="/subscriptions/{subscription_id}/resourceGroups/{rg_name}/providers/Microsoft.Storage/storageAccounts/{storage_name}",
    # The resource ID should be the ID of the resource you want to protect, e.g., a storage account
    is_enabled=True  # Enable the Advanced Threat Protection
)

# This creates an Application Security Group which can be used to group VMs for defining network security policies.
app_security_group = network.ApplicationSecurityGroup(
    resource_group_name="myResourceGroup",  # Specify the name of the resource group
    location="West US",  # Specify the location of the resource
    application_security_group_name="myAppSecurityGroup"  # Define the name for your Application Security Group
)

# Export the ID of the Advanced Threat Protection instance and Application Security Group.
pulumi.export("advanced_threat_protection_id", advanced_threat_protection.id)
pulumi.export("app_security_group_id", app_security_group.id)
```

This Pulumi code outlines the creation of Azure security resources but does not include every aspect of security posture management. You would typically include other resources, configure their properties, and link them to the resources you're managing. This includes setting up Azure policies, compliance checks, monitoring, and response strategies.

To use this code effectively, replace the placeholders with values specific to your Azure subscription, resources, and configuration. This includes `subscription_id`, `rg_name`, `storage_name`, and the names and regions of resources in the `network.ApplicationSecurityGroup`.

Security posture management is an ongoing process involving assessment, improvement, and maintenance to mitigate risks continuously. This Pulumi code provides a starting point, and adaptations are necessary to fit specific security needs and practices within your organization.
