There are many common vulnerabilities in software and systems and you must understand them to effectively secure your network systems. In this course, you'll learn about some of these vulnerabilities, as well as common attack mitigation techniques for network application style attacks. Before reviewing cybersecurity technologies in greater detail, you'll first look at the basics of cryptography and the critical role it plays in computer and network security. Finally, you'll explore some current cryptographic solutions and what they are used for. This course can be used in preparation for the 350-701: Implementing and Operating Cisco Security Core Technologies (SCOR) certification exam.
