    CONTENTS

     INTRODUCTION
     PASSWORDS MANAGEMNET IN CYBER SECURITY
     PASSWORD HASH SALTING
     SUITABLE PASSWORD
     AUTHENTICATION
     MULTI-FACTOR AUTHENTICATION
     GRAPHICAL PASSWORD AUTHENTICATION
    INTRODUCTION

     CYBER SECURITY –
    It refers to a set of techniques used to
    protect the integrity networks, programs and
    data from attack, damage or unauthorized
    access.
    There are many different ways that an
    attacker can infiltrate an IT system and most
    of them rely on pretty similar techniques
    One of them is Password attack
    PASSWORD MANAGEMENT IN CYBER SECURITY

     Methods to Manage Password


    1. Strong and long passwords
    2. Password Encryption
    3. Make the password pass the test
    4. Updating passwords frequently
    PASSWORD HASH SALTING

    A more secure way to store a password is to


    transform it into data that cannot be
    converted back to the original password.
    This mechanism is known as hashing.

    Key points in Hashing :


    1.Slight changes will produce an entirely
    different hash value
    2. Hash is similar to a fingerprint
    SUITABLE PASSWORD

    BRUTE FORCE ATTACK


    Brute-force attack is an attempt to discover a
    password by systematically trying every possible
    combination of letters, numbers, and symbols
    until you discover the one correct combination
    that works. 
    CHANGING PASSWORDS

     WHEN SHOULD WE CHANGE OUR PASSWORDS ?


    1. If You Suspect Unauthorized Access.  
    2. If You Discover Malware or Other Phishing Software.
    3. Shared Access.
    4. Logging in at Public Places.
    5. If You Haven’t Logged in for A While. 
    DO’s and DON’Ts IN PASSWORD HABITS
    AUTHENTICATION

    Authentication is the process of determining


    whether someone or something is, in fact, who or
    what it says it
     Verify the identity of a user , process or device
     Verifyingpermission to access an electronic device or
    computer network
    AUTHENTICATION AUTHORIZATION and
    ENCRYPTION

    AUTHENTICATION
    •Authentication is used by a server when the server needs
    to know exactly who is accessing their information or site.
    •Authentication is used by a client when the client needs
    to know that the server is system it claims to be.

    AUTHERIZATION
    •Authorization is a process by which a server determines if
    the client has permission to use a resource or access file.

    ENCRYPTION
    •Encryption involves the process of transforming data so
    that it is unreadable by anyone who does not have a
    decryption key.
    MULTI-FACTOR AUTHENTICATION

     Knowledge-based authentication factor


    Something You Know ( password )
     Location-based authentication factor
    Something you have ( OTPs , Smart card)
     Behavior-based authentication factor
     Something You are ( Fingerprint or Biometric method )
    GRAPHICAL USER AUTHENTICATION

     It is a form of authentication using images rather than letters, digits, or


    special character
    GRAPHICAL USER AUTHENTICATION

     Advantages
    1. User-friendly
    2. Provides high security
    3. Dictionary attacks are infeasible
     Disadvantages
    1.Registration and login take too long
    2.Requires more storage space because of images
