Basic Network and Database Security (edX)

This course gives you the background needed to understand basic types of network security. You will learn about computer networks including Local Area Networks, TCP/IP, the OSI Framework and routing basics. You will learn how networking affects security systems within an organization and network security controls that guard an organization from cybersecurity attacks.

In addition to networking, you will learn about database vulnerabilities and the tools/knowledge needed to research a database vulnerability for a variety of databases including SQL Injection, Oracle, Mongo and Couch. You will learn about various security data types associated with databases and organizations that define standards and provide tools for cybersecurity professionals. Ultimately you will learn how to safeguard an organizations sensitive information against data loss from cyberattacks.

This course will give you a basic understanding of network security and sensitive data protection services or as part of the overall Cybersecurity basics professional certificate.

This course is part of the IBM Cybersecurity Fundamentals Professional Certificate.
