NOTE:
Always compare the playlist with the syllabus before starting to study. Some topics might miss out, and you’ll have no other option but to mug up Stallings PPTs. The subject is dry, and you can score well if you can write a lot/mug-up a lot. Refer to the following: Sandeep Sarathi’s NIS full playlist
Module 1: Fundamentals of Security
The starting part of this module is purely theory, so better mug it up from PPTs. For guidance in Encryption techniques, AES and DES, refer to the following Sandeep Sarathi’s NIS full playlist
Module 2: Public Key Crypto Systems, Key Management & Distribution
Problems from RSA and ECC may come (refer to above playlist). For Key management, Distribution and other boring theory topics of this chapter, refer to the following playlist
