1 Introduction The amount of information being processed and stored has grown significantly in recent years. This makes organisations a prime target in which they frequently fall victim to cybercrime, reasons being cybercriminals are often financially motivated. One of the main issues organisations face, users often create easy passwords to remember, which makes their credentials susceptible to various brute force attacks. Cybercriminals use elaborate tools and techniques to crack user credentials which may later be used to perform an attack to the systems on the network. Authentication attacks occur on a daily basis which affect victims and corporations all over the world. The effects of a breach could result in sensitive information being compromised or a significant financial loss. There are various reasons that are thought to be correlated to authentication attacks. Some examples include, users using weak or the same passwords across multiple websites, organisations not salting and storing passwords in plain text. This aim of this report shall investigate the current tools and techniques used to conduct brute force attacks over both standard and SSH connection as well as offline. A number of usernames and passwords that range …show more content…
However, the type of encryption the password adopts also played a role in how efficient the brute force was. For instance, MD5 took 1 second, in contrast, SHA512 took 6 times longer. This illustrates brute force methods which are reliant on dictionaries or rainbow tables may have positive and negative characteristics. The positive characteristic is dictionaries contain a considerable amount of passwords that have previously been tried and tested, however, the downside is simple passwords are often still left out. For example, dictionaries that do not contain words with special

on the success and the process time of the dictionary attack. These passwords are based from
Why(2) : Many of the users used weak passwords which can be easily guessed by the hackers. Weak security measures was also an important reason which inlcudes weak encryption of the passwords by using outdated techniques for encryption. Updated security tools and strong password encryption might have helped to prevent this attack.
18.) Brute force When password guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because of the time a brute-force search takes.
During this course there have been a number of key learning points that would help every organization protect itself from a cyber-event. These include password management, patch management, security policies, encryption, and user training. In each of the cyber security breaches one or more of these standard security protocols were not used.
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
Despite the presence of network security devices such as firewalls and other security appliances, today's corporate networks are still vulnerable to both internal and external attacks by hackers intent on creating havoc. By proactively
The authentication process is a necessity for safeguarding systems against various forms of security threats, such as password-cracking tools, brute-force or wordbook attacks, abuse of system access rights, impersonation of attested users, and last but not least reply attacks just to name a

Memory is one of the most important things we have in our life because it involves in almost every part of our mind including problem solving, decision making, and our interest in life. We depend on it because it helps us make good decisions in life. Memory is the solution in learning and thinking and we use it in our everyday life. Think about the first time you kissed someone you loved or the time you learned how to tie your shoe for the first time. Those are all forms of memory whether they are short or long term. If you do not remember anything from the past then you are having a hard time managing your memory. Without memory you would be exposed to new and extraordinary things in life. Take for example, “Aliens, Love where are they?” by John Hodgman and “Jon” by George Saunders. John Hodgman and Jon both teach readers how without memories we would have a difficult time knowing who we are, who we love, and what we want in life.
Linton (2011, p.44) stated that hacking of network of common users and attacking their personal computers is one of the most threatening problems at present. It is happening in every second that results in a loss in several ways like loss of credentials, personal information etcetera. Although the use of personal computers and the internet has been increased rapidly, numbers of users who are the expert and have good knowledge to tackle the matters are very rare. In addition, time, as well as required equipment to protect hacking, is also very.
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.
Generally, every society has certain actions that are agreed upon as either being selfish or selfless. Psychological egoists try to raise questions about whether selflessness is even a possibility. James Rachel on the other hand tries to refute their argument. He believes that psychological egoism is the viewpoint that everything you do is selfish, because the motive behind any action is your own self-interest. (Sumner, pg.75)
The increasing volume and sophistication of cyber security threats including targeted data theft, phishing scams and other online vulnerabilities demand that we remain vigilant about securing our systems and information.
