Azure data breaches can be devastating, but there's good news: many of them are preventable. Properly configuring your Azure environment is a crucial step in protecting your data.
Regularly reviewing and updating access controls is a must. This includes removing unnecessary permissions and ensuring that users only have access to the resources they need.
A well-maintained Azure Active Directory (Azure AD) can also help prevent data breaches. This includes setting up multi-factor authentication and enforcing strong passwords.
Properly configuring Azure Storage is also essential. This includes using secure access keys and setting up data encryption.
Data Security Threats
Azure data breaches can occur through public exposure of sensitive data, which can be done through misconfigurations or third-party app connections. This can happen when sensitive data is left exposed in Azure storage.
Active Directory is a key area of concern, as it can be exploited by attackers to gain unauthorized access to sensitive data. This can happen through brute-force attacks or phishing attempts.
Varonis detects suspicious activity, such as excessive login attempts, data exfiltration, and configuration changes that may indicate a threat and put your critical Azure data at risk. This can be a sign of a rogue insider or a sophisticated attack.
Sensitive data leakage and exfiltration can also occur through public sharing of private keys or excessive downloads of sensitive data. Varonis monitors your Azure environment to detect these threats and provides real-time alerts when sensitive data is at risk.
Here are some common data security threats to watch out for in Azure:
- Sensitive data exposure through public exposure, third-party app connections, or misconfigurations
- Excessive access to sensitive data
- Data exfiltration through public sharing of private keys or excessive downloads of sensitive data
- Configuration changes that may indicate a threat
Varonis provides a human-readable audit trail of activity, making it easier to investigate potential data leakage and exfiltration. This can help you identify the source of the breach and take steps to prevent it in the future.
Preventing Data Leakage
Preventing Data Leakage is crucial in today's digital landscape. With the rise of cloud computing, sensitive data is more accessible than ever, making it a prime target for hackers.
Varonis monitors your Azure environment to detect sensitive data leakage and exfiltration. This is done by tracking activity and alerting you in real-time when sensitive data is compromised.
To prevent data leakage, you need to be aware of the common entry points. Sensitive blobs being made public, private keys being shared, and users downloading excessive amounts of sensitive data are all red flags.
Here are some common signs of data leakage:
- Sensitive blobs being made public
- Private keys being shared
- Users downloading excessive amounts of sensitive data
Varonis' human-readable audit trail of activity helps you investigate potential data leakage, making it easier to identify and contain the issue before it's too late.
Managing Azure Configuration
Managing Azure Configuration is crucial to preventing data breaches. Varonis can help with this by continuously surfacing misconfigurations that could put your sensitive Azure data and broader cloud environment at risk.
Varonis compares your configurations against common frameworks and regulations, such as HIPAA, GDPR, CCPA, and NIST, to identify where they drift from compliance. This helps you catch potential issues before they become major problems.
One common issue Varonis can help with is misconfigured default roles. This can allow internal and guest default roles to create and manage security groups or consent to applications, putting your Azure environment at risk.
Third-Party Application Risk Management
Third-party application risk management is a crucial aspect of managing Azure configuration. It's essential to keep an eye on third-party apps installed on Azure.
Varonis continuously scans and identifies third-party apps installed on Azure. This helps you stay on top of what's installed and running on your Azure environment.
You can monitor app activity to detect rogue apps performing suspicious or risky actions. This is a key step in preventing security breaches.
Varonis can identify and revoke stale, risky, or excessive app assignments. This helps you remove unnecessary apps and reduce the risk of security incidents.
To get a better understanding of your third-party app risk, consider the following:
- Third-party apps installed on Azure
- Rogue apps performing suspicious or risky actions
- Stale, risky, or excessive app assignments
Manage Configuration Drift
Managing configuration drift is crucial to protect your sensitive Azure data and broader cloud environment. This is where Varonis comes in, continuously surfacing misconfigurations that put your sensitive data at risk.
Varonis compares your configurations against common frameworks and regulations such as HIPAA, GDPR, CCPA, and NIST to identify where they drift from compliance. This helps you catch and fix misconfigurations before they become a problem.
Most solutions focus on threat prevention, but Varonis does all three: detection, prevention, and investigation. This makes it a powerful tool for managing configuration drift.
Misconfigured Default Roles
Managing misconfigured default roles in Azure is a critical task to ensure the security of your environment. This is because Varonis has identified that misconfigured internal and guest default roles can allow them to create and manage security groups or consent to applications.
These roles can be a major security risk if not properly configured. Identifying and fixing these issues is essential to protect your Azure environment.
Here are some common misconfigurations to look out for:
- Misconfigured internal default roles
- Misconfigured guest default roles
To fix these issues, Varonis provides detailed step-by-step instructions to help you immediately address any problems you may have. By following these instructions, you can ensure that your default roles are properly configured and your Azure environment is secure.
Automate Certificate Replacement
Automate Certificate Replacement is a crucial step in managing Azure Configuration to avoid disruptions. Preventing disruptions from certificate revocations is a top priority for maintaining continuity.
Certificate revocations can happen unexpectedly, causing downtime and lost productivity. Fast, automated solutions can help minimize the impact of these disruptions.
Automating certificate replacement ensures that expired or revoked certificates are replaced quickly and efficiently, without manual intervention. This streamlined process reduces the risk of human error and delays.
By automating certificate replacement, you can ensure continuity and minimize disruptions to your Azure Configuration. This proactive approach helps maintain the reliability and security of your infrastructure.
Protecting Sensitive Data
Protecting sensitive data is crucial to preventing data breaches in Azure.
To continuously assess your Azure data security posture, use real-time, customizable risk dashboards that visualize where sensitive data is at risk through public exposure, third-party app connections, or misconfigurations.
Active Directory plays a key role in managing data security.
Varonis automatically discovers and classifies sensitive data stored across structured and unstructured Azure resources with pinpoint accuracy.
Sensitive data can be at risk through excessive access, public exposure, and misconfigurations.
Varonis monitors your Azure environment to detect sensitive data leakage and exfiltration by sending real-time alerts when sensitive blobs are made public, private keys are shared, or users download excessive amounts of sensitive data.
Here are some ways Varonis helps prevent data leakage and exfiltration:
- Monitors your Azure environment to detect sensitive data leakage and exfiltration
- Provides real-time alerts when sensitive data is compromised
- Allows you to investigate potential data leakage with a human-readable audit trail of activity
Varonis also offers a range of products and resources to help you protect your sensitive data in Azure, including Universal Classification Support for Databases.
