1 INTRODUCTION
User authentication is a most important component in most computer security. It provides user with access control and user accountability. As we know there are many types of user authentication systems in the market but alphanumerical username/passwords are the most common type of user authentication. They are many and easy to implement and use. Due to the limitation of human memory, most users tend to choose short or simple passwords which are easy to remember. Surveys show that frequent passwords are personal names of family members, birth date, or dictionary words. In most cases, these passwords are easy to guess and vulnerable to dictionary attack. Today users have many passwords for personal computers, social networks, E-mail, and more. They may decide to use one password for all systems to decrease the memory burden, which reduce security. Graphical passwords is harder to guess or broken by brute force. If the number of possible pictures is sufficiently large, the possible password space of a graphical pass-word scheme may exceed that of text-based schemes and thus most probably offer improved security against dictionary attacks. The use of graphical password methods is gaining awareness because of these advantages. Graphical passwords were originally described by Blonder. In his description, an image would appear on the screen, and the user would click on a few chosen regions of it. If the correct regions were clicked in, the user would be
One of the other failures that the book presents us is the user’s weak password practice and how the intruder took advantage of this is to gain super user privileges and created several user accounts by gaining root privileges. All it takes is a one-time access as super user to establish his base into the defenders zone. This book describes how the intruder took advantage of brute force method to hack user accounts and password. Also, the intruder was smart enough to steal the password information file and even managed to encrypt all the dictionary words by using the same encryption algorithm and then compared those words with the stolen encrypted passwords file to find out passwords of user accounts. The scientists/ researchers at the laboratories who are not aware of such kind of exploitations made intruder’s work easy by having easy to guess passwords, never bothered to change the passwords from time to time or in fact did not realize the importance of having strong passwords in order to maintain and protect their research data in a safe and secure way. Even today, not all the users realize the importance of having strong/secure passwords and we come across such instances where intruders exploit users ignorance. (For example, Two years ago, before I enrolled in MS-CS program, I did not know how brute force attacks work or
Setting up a new computer can be a very intimidating task. There are several steps to ensure that your computer has the necessary setup for the best protection. Some of which include, the operating system settings that are built-into the computer, properly setup of firewall, security settings on the web browser configured correctly, and strong anti-virus software installed to protect the computer. After the computer is setup with a reasonable standard of security, a strong policy for passwords should be implemented to ensure account security along with ensuring the sites you utilize are in fact secure and who they say they are.
You will learn to recognize security events and baseline anomalies that might indicate suspicious activity.

The internet and online sites can be an open door for someone to commit identity theft. In order to combat this I need to continue to “create a strong password, by avoiding common or easy-to-guess passwords.” (Greene-Lewis, 2012) I use a password that contains both upper and lower case letters in addition to numbers and I often combine one or more words together to make it difficult for someone to guess my password. It is a bad idea to use common or easily guessed passwords, such as your birthdate or pet’s
Technology plays a huge role in today’s society. We use technology for several different reasons whether it is personal or business. When we have important protective documents, we have to protect them with passwords. Passwords must be strong and complicated, so hackers are not able to access our secure documents. It is very important to have strong password etiquette but should also be easy to remember.
Security is the most significant factor in authentication scheme. Our participants were enquired about how they often change their passwords and whether they have different passwords for different accounts, their answers were that they do not do that often; therefore, this would increase possibility of attacks. Here we briefly introduce some of the possible attacks which could break the Picture Pass Doodle system.
The interconnection of the world’s computers has brought forth significant security challenges. One of such challenges is in assuring only authorized users receive access to an organization's most critical asset, information. Authentication utilizing a weak authentication practice such as usernames and passwords are at times what stands between organizational data, and an unauthorized user. Unfortunately, user ineptness to memorize complex passwords tend to expose security gaps within a security program. Moreover, users willingly share their passwords tend to reveal additional shortcomings not present in the absence of such practice. In utilizing methods such as writing a password on a sticky note, or sharing a password

In this digital age, securing a digital information is very important. One of the various ways to protect our digital information is authenticating properly. Likewise, among three factors of authentication, password is a factor that a user must know. There is always someone out there interested in grabbing our digital information, and a password can authenticate someone else to grab such information. Thus, it is important to be careful with protecting a password. Brute-force attack is one of the attacks someone can use to guess and match the password. Brute-force attack includes lot of dictionary words, so, it is important to create a strong password with words that are not in dictionary and include different special characters in password
Information is the most valuable commodity that individuals and global corporations use to grow financially, economically, and independently. The protection and security of the information is essential. One of the most vital foundations of protection information is the authentication process. The authentication process is utilized to protect computer and network systems against various types of security threats, such as password-cracking tools, password dictionary attacks, mistreatment of user access rights, and any potential unauthorized attacked. Understanding how to authenticate users and the accessible information that is readily available on system networks can help prevent future issues as well as provide insight into the developmental process for new systems. In addition, authentication is simply determining whether someone or some machine is, in fact, who or what they declared there to be. This process directly reflects on and correlates to the readiness and ease of access to information and the protection of it.
Technology is constantly changing, leading us to adapt to its innovation. However, one aspect of technology has stood the test of time for a long time. Passwords as a form of authenticating and securing your digital accounts have not budged much. But with the rise of cybercrime, it seems the old way of doing things is finally having to pave way for something new: two-factor authentication.
Passwords for access to personal phones, computers, online portals, and websites has become very prevalent and the best practice for authentication. Additionally, passwords authenticate mobile phones, computer networks and databases for many software applications. However, ensuring that passwords are encrypted, and safe have become one of the greatest challenges for most organizations. This paper will review some of the vulnerabilities of the use of passwords and provide controls to implementation to assist with the management and handling of passwords.
As incidents of cybercrime are escalating at unprecedented rates with each passing day, you can't bank on the ancient defensive methodology of password protection alone. Professional hackers can break even the most difficult password using the sophisticated technologies.
