Today's complex computing environments are rife with vulnerabilities. Keeping your organizational data safe requires employing today's best data security practice: adopting the premise that identity and access management provide the new and true security perimeter.
Powerful identity and access management (IAM) models of public cloud providers like Microsoft Azure, enable the deployment of applications and data with far greater protection than what is possible in traditional cloud security. However, these cloud provider IAM solutions are not without risk when misused. If your organization uses Microsoft's Azure, then you'll want to avoid making the Azure configuration errors that are most common among like-minded users.
System oversight: Double check configuration
The most common data security mistake made by most companies is their lapse of system oversights after they've engaged the Azure AD platform. While Azure does perform amazing feats, it still requires appropriate configuration and attention to retain its mastery of data protection. Further, ongoing attention to these details also will save money while optimizing the performance of your system.
Take precautions with data security tune-ups
Tune-up fundamental access procedures
There are two types of cybercriminals to guard against:
- Hackers - those external malfeasants who gain entry through phishing or other outside-in ploys, and
- Insiders - trusted colleagues, staffers and business partners who exploit their position to gain access to information that they use for personal gain.
Fundamental access controls, including Role-Based Access Control (RBAC) and Multifactored Authorizations (MFAs), can prevent intrusions by both types of criminals. These controls verify the identity of valid users, then monitor their usage to ensure it remains within the security parameters mandated by their work.
Tune-up subsequent access privileges
Network Security Groups manage ingress and egress to the Azure resources contained within an Azure network. Often, to ease access and speed productivity, Admins will set broader security configurations on these controls so that essential access isn't inadvertently denied. However, this broad access rule also allows insiders to tap into resources they don't need to access. Setting the controls with the least permissive settings will prevent intrusions through these portals.
Monitor your activity logs
Your Azure databanks also record who's accessing your Azure resources and that information can alert you to inappropriate use or activity. The Azure Activity Log integrates with Azure's Operations Management System (OMS) and Power BI solutions, allowing you to monitor all of the create, delete, update, and action behaviors occurring across your Azure network.
Watch your resting data, too
Not all your data is used all the time, but most of it still needs storage and security until it's needed or permanently deleted. Too many companies fail to adequately protect their 'data at rest,' leaving them vulnerable to external and internal intrusions. Encrypting it, which makes it unintelligible to unauthorized entities, maintains its integrity and keeps it secure. Azure automatically encrypts all new data storage banks by default; your organization should keep those settings and apply them to your older stores, as well.
Avoid data optimization errors
Another error often made in Azure's configuration is the failure to optimize its operational tools.
Optimize your resource tags
Tagging Azure resources identifies them within the database so that other resources can find and access them. Managing tags is a critical operational and security function since they allow access to vital corporate resources—accordingly, only users with write access to the Microsoft.Resources/tags resource can apply tags to resources.
Optimize your inventory utilization
Just like resting data, not all resources are in high demand all the time. Maintaining them for that level of functioning is expensive, so Azure gives you the power to scale them down when demand is low. Tracking your corporate resources allows you to scale up and down according to your market sector's requirements.
Watch for Expensing Errors
Monitor your metrics
Resource tracking provides not just information about cyclical demands on your organization, but also about the costs of maintaining readiness to meet those demands. Overprovisioned but unused resources waste money. Azure can alert you when your resources are sitting idle so you can adjust your settings appropriately.
Access the Azure Resource Manager (ARM)
You'll need control over all your Azure assets to maximize your organizational security, and the ARM gives you that control. This overarching layer lets you create, enable, update, and delete the full scope of your Azure account's resources, including your access and identity controls. The ARM manages your account using templates, not scripts, so that you can control all your assets as a group. It applies access control to all your services by the native integration of RBAC in the management platform, as well as facilitates tagging, billing and ensuring consistent scaling.
Explore identity and data governance platforms
Public cloud IAM security models are a double-edged sword. One edge provides excellent promise with the ability to architect strong IAM based security into applications that significantly improve data protection. Unfortunately, the other side can introduce attack vectors if not correctly architected and configured. In this article, we highlighted just a handful of common errors that can lead to exposed data, however, with the right tools many of these common errors can be detected, prevented and remediated.
Organizations looking to reduce risk in Azure should look at identity and governance platforms that help them graph all of their trust relationships between human and non-human identities. Your solution should include, but not be limited to, getting to and maintaining least privilege, locking down “crown-jewel” data, shifting left by integrating DevOps and IT teams, and more. By utilizing an identity and data governance platform, your organization can properly detect and manage any Azure configuration issues.
