1 section • 13 lectures • 1h 32m total length

Overview of Information Security Policies16:06
Explore how information security policies establish purpose, scope, and controls to protect confidentiality, integrity, and availability, covering data classification, access control, acceptable use, and vendor management.
Session2-Types of Threats and Security Attacks10:51
Session3-Services and Security Mechanisms for Messages5:55
Explore security services and mechanisms for messages, including authentication, confidentiality, integrity, non-repudiation, and availability per x.800 and rfc standards. Learn how encipherment, digital signatures, and traffic padding secure data.
Session4-Information Integrity Services5:06
Explore information integrity services driven by security policies, covering access control, data confidentiality and integrity, authentication, encryption, and auditing, with organizational, legal, and engineering measures.
Session5-Cryptographic and Non Cryptographic Attack6:19
Explore cryptanalytic and non cryptanalytic attacks within a network security model, including sender and receiver, secret keys, and security protocols. Examine symmetric and asymmetric encryption, cipher algorithms, and cryptography fundamentals.
Session 6-Cipher Technique: Substitution Technique4:48
Session7-Cipher Techniques Playfair Cipher In Detail9:30
Session8: Poly Alphabetic and Vignere Cipher6:56
Session9- Double Transposition Technique3:45
Double transposition technique uses two rounds of columnar transposition to strengthen encryption. It first grids the plaintext, applies the first key order, then regrids and applies the second key order.
Session10-Diffie Hellman Key Exchange3:30
Session11- Hill Cipher5:45
Learn the Hill cipher, a linear algebra based encryption method using a 3 by 3 key matrix and modulo 26 to encrypt and decrypt plaintext.
Session 12-Eliptc Curve Cryptography5:38
Learn elliptic curve cryptography (ecc), a public key system with smaller key sizes than rsa, featuring trapdoor curve function and public keys Na, Nb, enabling encryption m + k pb.
Session13- Pretty Good Privacy8:23

Description

Cryptography and information security are vital areas for safeguarding digital communications and data. In this course you will get basic idea on ensuring the safety of information by reducing potential threats is known as information security. This is achieved by the three main concerns are data availability, integrity, and secrecy, which is often called the CIA triad. In this course initially you will understand the overview of information security polices. In that you will identify how the organizations need to implement security policies to improve security. Then you will understand how the threats and attacks vulnerability. In that you will understand the difference between threat and attack in more detail. Next you will understand regarding services and security mechanisms for messages in more detail.

Then this course highlights the information integrity services in more detail. After understanding all the security concepts this course next you will get into cryptography concepts. In that you will understand to distinguish between cryptography and non cryptography attacks . Then you will understand the substitution techniques and transposition techniques in more detail. Then you will understand various substitution techniques such as Playfair cipher, poly alphabetic cipher etc. Then you will explore regarding double transposition techniques in detail. Further you will explore various security algorithms such as ECC, Diffie Hellman key exchange and PGP techniques.
