Event Information

  1. The Microsoft.KeyVault.vaults.keys.read event in Azure for AzureSecurityService indicates that a key within an Azure Key Vault has been read.
  2. This event is triggered when a user or application retrieves the value of a key from the Azure Key Vault.
  3. It is important to monitor this event as it provides visibility into key access and can help detect any unauthorized or suspicious activities related to key retrieval.

​
Examples

  1. Unauthorized access to sensitive data: If security is impacted with Microsoft.KeyVault.vaults.keys.read in Azure for AzureSecurityService, it could potentially allow unauthorized users to read the keys stored in the Azure Key Vault. This can lead to a compromise of sensitive data, such as encryption keys or secrets, which can be used to gain unauthorized access to other resources or systems.

  2. Data integrity and confidentiality risks: If security is impacted with Microsoft.KeyVault.vaults.keys.read in Azure for AzureSecurityService, it can result in data integrity and confidentiality risks. An attacker with access to the keys can potentially decrypt encrypted data or tamper with the data stored in Azure Key Vault, leading to unauthorized modifications or exposure of sensitive information.

  3. Compliance and regulatory violations: If security is impacted with Microsoft.KeyVault.vaults.keys.read in Azure for AzureSecurityService, it can result in compliance and regulatory violations. Organizations that are subject to specific compliance standards, such as PCI DSS or HIPAA, may face penalties or legal consequences if encryption keys or sensitive data are compromised. It is important to ensure that proper access controls and monitoring mechanisms are in place to mitigate these risks and maintain compliance.

Remediation

​
Using Console

To remediate the AzureSecurityService issue using the Azure console, you can follow these step-by-step instructions:

  1. Enable Azure Security Center:

    • Log in to the Azure portal.
    • Search for “Security Center” in the search bar and select the Security Center service.
    • Click on “Pricing & settings” in the left-hand menu.
    • Select the subscription and resource group where the AzureSecurityService is deployed.
    • Click on “Enable” to enable Azure Security Center for the selected subscription.

  2. Configure Security Policies:

    • In the Azure Security Center, click on “Security policy” in the left-hand menu.
    • Select the subscription and resource group where the AzureSecurityService is deployed.
    • Click on “Add policy” to create a new security policy.
    • Configure the policy settings based on the specific requirements and compliance standards.
    • Save the policy and assign it to the relevant resources, including the AzureSecurityService.

  3. Monitor and Remediate Security Alerts:

    • In the Azure Security Center, click on “Security alerts” in the left-hand menu.
    • Review the list of security alerts related to the AzureSecurityService.
    • Investigate each alert to understand the potential security risks.
    • Take appropriate actions to remediate the alerts, such as applying security patches, updating configurations, or implementing additional security measures.
    • Continuously monitor the security alerts and remediate any new issues that arise.

Note: The exact steps may vary slightly depending on the Azure portal version and interface changes. It is always recommended to refer to the official Azure documentation for the most up-to-date instructions.

​
Using CLI

To remediate the AzureSecurityService issue in Azure using Azure CLI, you can follow these steps:

  1. Enable Azure Security Center for your subscription:

    • Run the following command to enable Azure Security Center for your subscription: 
      az security pricing create --name 'Default' --tier 'Standard'

  2. Configure Azure Security Center recommendations:

    • Use the following command to configure Azure Security Center recommendations: 
      az security auto-provisioning-setting update --name 'default' --auto-provision 'On'

  3. Enable Just-In-Time (JIT) VM access:

    • To enable JIT VM access, execute the following command: 
      az security jit-policy update --name 'default' --resource-group 'your-resource-group' --location 'your-location' --state 'Enabled'

Please note that you need to replace ‘your-resource-group’ and ‘your-location’ with the appropriate values specific to your Azure environment.

​
Using Python

To remediate AzureSecurityService issues in Azure using Python, you can follow these steps:

  1. Enable Azure Security Center: Use the Azure SDK for Python to enable Azure Security Center for your Azure subscription. You can use the azure-mgmt-security package to manage security settings programmatically. Here’s an example script:
from azure.identity import DefaultAzureCredential
from azure.mgmt.security import SecurityCenter

# Authenticate using default credentials
credential = DefaultAzureCredential()

# Create a Security Center client
security_center_client = SecurityCenter(
    credential=credential,
    subscription_id="<your-subscription-id>"
)

# Enable Azure Security Center for your subscription
security_center_client.auto_provisioning_settings.create_or_update(
    resource_group_name="<your-resource-group>",
    auto_provisioning_setting_name="<your-setting-name>",
    auto_provisioning_setting={
        "auto_provision": "On"
    }
)
  1. Configure Security Policies: Use the azure-mgmt-security package to configure security policies for Azure Security Center. You can define policies to enforce specific security controls and compliance standards. Here’s an example script:
from azure.identity import DefaultAzureCredential
from azure.mgmt.security import SecurityCenter

# Authenticate using default credentials
credential = DefaultAzureCredential()

# Create a Security Center client
security_center_client = SecurityCenter(
    credential=credential,
    subscription_id="<your-subscription-id>"
)

# Configure a security policy
security_center_client.policies.create_or_update(
    resource_group_name="<your-resource-group>",
    policy_name="<your-policy-name>",
    policy={
        "displayName": "My Security Policy",
        "description": "This policy enforces security controls",
        "policyRule": {
            "if": {
                "field": "type",
                "equals": "Microsoft.Compute/virtualMachines"
            },
            "then": {
                "effect": "audit",
                "details": {
                    "type": "AuditIfNotExists",
                    "existenceCondition": {
                        "field": "Microsoft.Compute/virtualMachines/osProfile.linuxConfiguration.ssh.publicKeys[].keyData",
                        "equals": ""
                    }
                }
            }
        }
    }
)
  1. Monitor Security Events: Use the azure-mgmt-monitor package to monitor security events in Azure. You can retrieve security event logs and analyze them for potential security issues. Here’s an example script:
from azure.identity import DefaultAzureCredential
from azure.mgmt.monitor import MonitorManagementClient

# Authenticate using default credentials
credential = DefaultAzureCredential()

# Create a Monitor client
monitor_client = MonitorManagementClient(
    credential=credential,
    subscription_id="<your-subscription-id>"
)

# Retrieve security event logs
security_event_logs = monitor_client.activity_logs.list(
    filter="eventTimestamp ge 2022-01-01 and eventTimestamp le 2022-01-31 and category eq 'Security'"
)

# Process security event logs
for log in security_event_logs:
    print(log.event_name.value, log.resource_id, log.event_timestamp)

Please note that you need to install the required Azure SDK packages (azure-mgmt-security and azure-mgmt-monitor) before running these scripts.
