As organizations consider their journey to establishing a strong Zero Trust culture, they must adopt a data-centric approach, and this begins with ensuring database security. Data, or more specifically, knowing your data, is at the heart of Zero Trust. This means databases must be considered critical assets with the appropriate security considerations applied.

DynamoDB is a fully managed NoSQL database service offered by Amazon Web Services (AWS). It is renowned for its scalability, dependability, and easy connection with other AWS services. Notwithstanding its manifold advantages, organizations continue to place a high premium on guaranteeing the security of data stored in DynamoDB. By default, DynamoDB can be accessed over the public network using HTTPS, ensuring secure communication with SSL/TLS encryption.

Today, organisations store a lot of sensitive data in their database systems. This could be customer info, financial records, intellectual property, etc. Protecting this from unauthorised access is key; database penetration testing helps achieve this by finding holes in the system.

SQL injection vulnerabilities may affect any website or application that employs an SQL database, such as MySQL, Oracle, SQL Server, or others. Malicious actors may use them to gain unauthorized access to sensitive information, such as customer information, personal data, trade secrets, and more. For example, SQL injections were responsible for 23% of global vulnerabilities in 2023, Moreover, 19% of the internet faces cross-site scripting (stored) attacks.

Microsoft SQL Server is a popular relational database management system (RDBMS). However, determining the effective access rights of users is difficult because in Active Directory (AD) environments, effective access is determined based on not only the user’s direct permissions but also their membership in SQL Server roles, AD groups and Local Windows groups.

In an SQL Server, roles act like security groups that control what users can do within the database environment. The roles designate the access groups determining who can access specific databases and what they can do with the data within those databases. The public role is a special database role that everyone is assigned by default when they become a member of a database. By default, the public role has very limited permissions, often no permissions at all.

SQL Agent proxies are a form of built-in service that allows the schedule and running of automated tasks within SQL Server. These tasks can perform various actions related to database management. The msdb database is a crucial system database in Microsoft SQL Server which primarily serves SQL server agents. These databases store information related to SQL Agent jobs, including their configuration, execution history, vital system tables and data.

The recent cyberattack on Ascension Medical, Change Healthcare and several UK hospitals is a stark reminder of the vulnerabilities within the healthcare sector. The May 8, 2024, attack disrupted access to Electronic Health Records (EHR) for two weeks across Ascension's 140-hospital system, forced some hospitals to divert ambulances and rely on manual record-keeping, and has led to patient class-action lawsuits regarding potential data exposure.

SQL Server is a widely used relational database management system (RDBMS) developed by Microsoft. It provides secure, scalable and high-performance storage and management of structured and unstructured data. SQL Server offers a wide range of features and tools for database administration, development, business intelligence and advanced analytics.

Safeguarding your data is not just an option—it’s a necessity. Cyber threats are evolving at an unprecedented pace, and your database could be the next target. Whether you’re managing sensitive customer information or intricate analytics, database security should be at the top of your priority list. This article dives deep into the top 7 database security best practices that will help you fortify your defenses.
