Password Design Guidelines:

1. Complexity:
   1. Use a combination of uppercase and lowercase letters, numbers, and special characters (!, @, #, etc.).
   1. Avoid using easily guessable patterns or sequences (e.g., “123456” or “password”).
   1. Aim for a minimum password length of 8-12 characters.
2. Avoid Common Words:
   1. Do not use easily guessable words, phrases, or personal information (e.g., names, birthdays, pet names) in passwords.
   1. Consider using a passphrase or combination of unrelated words for increased complexity and memorability.
3. Unique and Diverse:
   1. Use different passwords for each account or system to prevent a single breach compromising multiple accounts.
   1. Consider using a password manager to generate and store complex passwords securely.
4. Regular Updates:
   1. Change passwords periodically (e.g., every 3-6 months) to reduce the risk of password compromise.
   1. Immediately update passwords if there’s a suspicion of unauthorized access or a security breach.
5. Multi-Factor Authentication (MFA):
   1. Whenever possible, enable MFA for additional security layers, requiring a second form of verification (e.g., SMS code, biometric scan) along with the password.
6. Avoid Common Password Mistakes:
   1. Avoid using easily guessable variations of common words (e.g., “p@ssw0rd” for “password”).
   1. Do not share passwords via insecure channels or store them in plaintext formats.

Authentication Process:

1. User Identification:
   1. The authentication process begins with identifying the user attempting to access a system or account. This may involve entering a username, email address, or user ID.
2. Password Entry:
   1. After user identification, the user is prompted to enter their password. The system verifies the entered password against the stored password hash.
3. Password Hashing:
   1. Passwords are not stored in plaintext but rather as hashed values using cryptographic hashing algorithms (e.g., SHA-256). This ensures that even if the password database is compromised, the actual passwords remain protected.
4. Password Verification:
   1. The entered password’s hash value is compared with the stored hash value in the system’s password database. If the hashes match, the password is considered valid.
5. Authentication Factors:
   1. Depending on the security requirements, additional authentication factors may be required, such as:
      1. Knowledge factors (passwords, PINs).
      1. Possession factors (smartphone, hardware tokens).
      1. Inherence factors (biometric data like fingerprints, facial recognition).
6. Multi-Factor Authentication (MFA):
   1. If MFA is enabled, the user is prompted to provide a second form of authentication after entering the password. This could be a one-time code sent via SMS or generated by an authenticator app.
7. Access Granted/Denied:
   1. If the authentication process is successful (valid username/password and additional factors if required), access to the system or account is granted.
   1. If authentication fails (e.g., incorrect password or insufficient authentication factors), access is denied, and the user may be prompted to retry or reset their password.
8. Account Lockout and Security Measures:
   1. Some systems implement account lockout policies after multiple failed authentication attempts to prevent brute-force attacks.
   1. Security measures such as CAPTCHA challenges or account recovery options may be provided to verify user identity and prevent unauthorized access.

By following password design guidelines and understanding the authentication process, individuals and organizations can significantly enhance their cybersecurity posture, reduce the risk of unauthorized access, and protect sensitive information from potential threats and attacks.

II) Write short notes on the following in not more than 200 words each. (10×2= 20 Marks)
