Introduction to Information Security - I

Where the course starts

This lecture series treats information security as a discipline that begins with clear definitions and terminology before it moves into how the core goals are put into practice. Early lectures cover why systems need protection, and later ones turn to the control mechanisms that guard them day to day.

Practical topics

Access control gets close attention, both the administrative side of policies and people and the technical side of systems that enforce them. Password strength and multifactor authentication are examined as real-world problems rather than checkboxes, which makes the material useful beyond exam preparation.

Who it suits

• Students who want a structured introduction to security concepts taught by IIT Madras faculty
• Working professionals who need the vocabulary of policies, standards and roles
• Learners preparing for later study in applied security

The lectures build on one another, so follow the sequence rather than dipping in and out.
