An all-encompassing guide to securing your database and applications against costly cyberattacks!

In a time when the average cyberattack costs a company $9.48 million, organizations are desperate for qualified database administrators and software professionals. Hackers are more innovative than ever before. Increased cybercrime means front-end applications and back-end databases must be finetuned for a strong security posture.

In this extensive and accessible guide, Dr. R. Sarma Danturthi provides a solutions-based approach to help you master the tools, processes, and methodologies to establish security inside application and database environments. It discusses the STIG requirements for third-party applications and how to make sure these applications comply to an organization’s security posture. From securing hosts and creating firewall rules to complying with increasingly tight regulatory requirements, this book will be your go-to resource to creating an ironclad cybersecurity database.

In this guide, you'll find: Tangible ways to protect your company from data breaches, financial loss, and reputational harm Engaging practice questions (and answers) after each chapter to solidify your understanding Key information to prepare for certifications such as Sec+, CISSP, and ITIL Sample scripts for both Oracle and SQL Server software and tips to secure your code Advantages of DB back-end scripting over front-end hard coding to access DB Processes to create security policies, practice continuous monitoring, and maintain proactive security postures
