Read The Section In This Weeks Reading Assignment On Secure Passwords

Read the section in this week's reading assignment on secure passwords. Then pick three passwords: one not secure, one acceptable, and one very secure. Then write a brief description of the passwords you have chosen, indicating why they are secure or not secure.

Paper For Above instruction

In this paper, I will analyze three passwords categorized as not secure, acceptable, and very secure. Each password's security level will be evaluated based on best practices for password strength, including length, complexity, unpredictability, and resistance to common attack methods such as brute-force or dictionary attacks. This assessment is grounded in literature on authentication, password security fundamentals, and current best practices.

The first password, considered not secure, is "password123." This password is highly insecure because it is a common and predictable phrase. It uses simple, sequential numbers that are frequently used and easily guessed by attackers using common password lists. Its minimal length and lack of complexity (no special characters, minimal uppercase letters) make it vulnerable to dictionary and brute-force attacks (Bonneau et al., 2012). Many attackers exploit such predictable passwords, significantly reducing their security.

The second password, deemed acceptable, is "Summer2024!". This password offers a moderate level of security. It combines a common word with numbers and a special character, increasing its complexity compared to simpler passwords. However, it still incorporates predictable patterns—the word "Summer" paired with a year—making it somewhat vulnerable, especially if attackers are aware of common guessing strategies. While better than the previous password, it does not meet the criteria for a highly secure password, as it could potentially be guessed through targeted attacks or using password-cracking tools that incorporate common phrases and patterns (Florêncio & Herley, 2010).

The third password, classified as very secure, is "D9$kP!7zQ@vL4wX#". This password demonstrates high security standards through its length (16 characters), unpredictability, and complexity. It contains a mixture of uppercase and lowercase letters, numbers, and special characters in a seemingly random sequence. Such passwords are resistant to brute-force and dictionary attacks because of their enormous combination space (Bonneau et al., 2012). Randomly generated passwords of this nature are recommended for protecting sensitive accounts and data because they are extremely difficult for attackers to guess or crack using current computational methods.

In conclusion, password security varies significantly based on complexity, unpredictability, and length. Weak passwords like "password123" are highly vulnerable and should be avoided; moderate passwords like "Summer2024!" are better but still susceptible to targeted guessing; and strong, complex passwords such as "D9$kP!7zQ@vL4wX#" provide robust protection against common attack methods. Organizations and individuals should prioritize creating and managing passwords that meet high-security standards, possibly supplemented by multi-factor authentication to further enhance account security (Florêncio & Herley, 2010; Bonneau et al., 2012).
