Databases sit at the heart of modern businesses. They support everyday apps, reports and AI tools. For example, any time you engage a site that requires a username and password, there is a database at the back end that stores your login information. As organizations adopt multi-cloud and hybrid architectures, databases are generated all the time, creating database sprawl. As a result, tracking and managing every database, catching misconfigurations and vulnerabilities, knowing where sensitive information lives, all becomes increasingly difficult leaving a huge security gap. And because companies store their most valuable data, like your login information, credit card and social security numbers, in databases, databases are the main target for threat actors. Securing databases is no longer optional, yet getting started can feel daunting. Database security needs to address the gaps mentioned above – help organizations see their databases to help them monitor for misconfigurations and vulnerabilities, sensitive information and any suspicious activities that occur within the database that are indicative of an attack. Further, database security must meet customers where they are – in multi-cloud and hybrid environments. This five part blog series will introduce and explore database-specific security needs and how Defender for Cloud addresses the gaps through its deep visibility into your database estate, detection of misconfiguration, vulnerabilities and sensitive information, threat protection with alerts and Integrated security platform to manage it all. This blog, part one, will begin with an overview of today’s database infrastructure security needs. Then we will introduce Microsoft Defender for Cloud’s unique database protection capabilities to help address this gap. Modern Database Architectures and Their Security Implications Modern databases can be deployed in two main ways: on your own infrastructure or as a cloud service. In an on-premises or IaaS (Infrastructure as a Service) setup, you manage the underlying server or virtual machine. For example, running a SQL Server on a self-managed Windows server—whether in your data center or on a cloud VM in Azure or AWS—is an IaaS deployment (Microsoft Defender for Cloud refers to these as “SQL servers on machines”) that require server maintenance. The other approach is PaaS (Platform as a Service), where a cloud provider manages the host server for you. In a PaaS scenario, you simply use a hosted database service (such as Azure SQL Database, Azure SQL Managed Instance, Azure Database for PostgreSQL, or Amazon RDS) without worrying about the operating system or server maintenance. In either case, you need to secure both the database host (the server or VM) and the database itself (the data and database engine). It’s also important to distinguish between a database’s control plane and data plane. The control plane includes the external settings that govern your database environment—like network firewall rules or who can access the system. The data plane involves information and queries inside the database. An attacker might exploit a weak firewall setting on the control plane or use stolen credentials to run malicious queries on the data plane. To fully protect a database, you need visibility into both planes to catch suspicious behavior. Effective database protection must span both IaaS and PaaS environments and monitor both the control plane and data plane because they are common targets for threat actors. Security teams can then detect suspicious activity such as SQL injections, brute-force attempts, and lateral movement through your environment. A Unified Approach to Database Protection Built for Multicloud Modern database environments are fragmented across deployment models, database ownership, and teams. Databases run across IaaS and PaaS, span control and data planes, and in multiple clouds, yet protection is often pieced together from disconnected point solutions Microsoft Defender for Cloud is a cloud native application protection platform (CNAPP) solution that provides a unified, cloud-native approach to database protection—bringing together discovery, posture management, and threat detection across SQL (Iaas and Paas), open-source relational databases (OSS), and Cosmos DB databases. Defender for Cloud’s database protection uses both agent-based and agentless solutions to protect database resources on-premises, hybrid, multi-cloud and Azure. A lightweight agent-based solution is used for SQL servers on Azure virtual machines or virtual machines hosted outside Azure and allows for deeper inspection, while an agentless approach for managed databases stored in Azure or AWS RDS resources provide protection with seamless integration. Additionally, Defender for Cloud brings in other signals from the cloud environment, surfacing a secure score for security posture, an asset inventory, regulatory compliance, governance capabilities, and a cloud security graph that allows for proactive risk exploration. The value of database security in Defender for Cloud starts with pre and post breach visibility. Vulnerability assessment and data security posture management helps security admins understand their database security posture and, by following Defender for Cloud’s recommendations, security admins can harden their environment proactively. Vulnerability assessments scans surface remediation steps for configurations that do not follow industry’s best practices. These recommendations may include enabling encryption when data is at rest where applicable or database server should restrict public access ranges. Data security posture management in Defender for Cloud automatically helps security admins prioritize the riskiest databases by discovering sensitive data and surfacing related exposure and risk. When databases are associated with certain risks, Defender for Cloud will provide its findings in three ways: risk-based security recommendations, attack path analysis with Defender CSPM and the data and AI dashboard. The risk level is determined by other context related to the resource like, internet exposure or sensitive information. This way, Security admins will have a solid understanding of their database environment pre-breach and will have a prioritized list of resources to remediate based on risk or posture level. While we can do our best to harden the environment, breaches can still happen. Timely post-breach response is just as important. Threat detection capabilities within Defender for Cloud will identify anomalous activity in near real time so SOC analytes can take action to contain the attack immediately. Defender for Cloud monitors both the control and the data plane for any anomalous activity that indicates a threat, from brute force attack detections to access and query anomalies. To provide a unified security experience, Defender for Cloud natively integrates with the Microsoft Defender Portal. The Defender portal brings signals from Defender for Cloud to provide a single cloud-agnostic security experience, equipping security teams with tools like secure score for security posture, attack paths, and incidents and alerts. When anomalous activities occur in the environment, time is of the essence. Security teams must have context and tools to investigate a database resource, both in the control plan and the data plane, to remediate and mitigate future attacks quickly. Defender for Cloud and the Defender portal brings together a security ecosystem that allows SOC analysts to investigate, correlate activities and incidents with alerts, contain and respond accordingly. Take Action: Close the Database Blind Spot Today Modern database environments demand more than isolated controls or point solutions. As databases span hybrid and multiple clouds, security teams need a unified approach that delivers visibility, context, and actionable protection where the data lives. Microsoft Defender for Cloud provides organizations the visibility into all of your databases in a centralized Defender portal using its unique control and data plane findings so that security teams can identify misconfigurations. prioritize them based on cloud-context risk-based recommendations or proactively identify other attack scenarios using the attack path analysis while SOC analysts can investigate alerts and act quickly. Follow this story for part two. We’ll go into Defender for Cloud’s unique visibility into database resources to find misconfiguration gaps, sensitive information exposure, and contextual risks that may exist in your environment.

Introduction: Many organizations use multiple cloud providers today, which makes security misconfigurations more likely due to the solution scale and complexity. Moreover, different practices and concepts among each cloud provider’s implementation create bigger internal knowledge gaps. No matter how many cloud providers an organization uses, a database is the core of each application, storing the organization’s most valuable data: PII, financial and payment information, medical information, and other sensitive data. This makes databases the most attractive attack target for any threat actor – from inside or outside. Even though there is more awareness of exposure misconfigurations (thanks to cybersecurity education and posture management products that reveal these issues), public datasets show that the most risky database misconfiguration - exposing databases to the internet is not going down. This fact emphasizes the importance of threat protection that will act as a last line of defense and help detect, in near real-time, attacks that endanger databases and the critical data they contain. Internet exposed databases count through time. (Source: Time series · General statistics · The Shadowserver Foundation) Announcement: Microsoft Defender for open-source relational databases have been long focusing on providing comprehensive protection for Azure databases.
