Abstract:
In the age of digitalization, passwords play a significant role to protect user information. The growing number of data breaches has become a major problem allowing unauthorised parties to access confidential data. Over the years, passwords have been the first factor of authentication that is used in various segments, such as web applications, banking, e-commerce, and applications for authentication, etc. In most cases, the passwords are usually assigned to or created by the authorized user, and must be kept secret to keep unauthorized users from having access to information it is meant to protect. However, recent attacks have shown that these passwords are vulnerable to attacks such as, the dictionary, brute force, man in the middle, traffic interception, social engineering, and key logger attack, etc. In this paper, we discuss different types of passwords that prevent unauthorised access to protect users’ information. We analyze various attack techniques that are leveraged in many ways to obtain passwords. We also discuss the available protection techniques that aim to protect passwords. However, our analysis reveals that the protection techniques are not sturdy and fail to provide enough protection against the most utilised attack techniques, hence, requiring to have more advanced techniques in place.
