Passwords
This lab was to discuss the vulnerability of weak passwords. We were thought how to crack our own passwords using a method called “john the ripper”. We also found out how secure various passwords and how long it would take for a desktop Pc to crack these passwords. We looked up various methods and applications to crack passwords.
Report Part One:
Explain & Preventions
Dictionary Attack =
A technique used to try and find the user’s password by trying hundreds of different possibilities many of these words from the dictionary.
Prevention =
Every time the password is typed in incorrectly the response time increases from the same ip address used.
Brute Force Attack =
A technique that is a trial-and-error method, it generates large quantities of consecutive guesses to try and obtain the users password.
Prevention =
If a hacker fails to login after the third time an account lockout policy can be implemented to prevent further attempts and only an administrator can unlock the account.
Weak Password =
A password that easy to crack by a computer or a human, People can use common passwords with no numerals or special characters and no upper case characters which make this much easier for someone to obtain their passwords or personal data.
Report Part Two:
Description of attack and results
Firstly we created 6 user accounts; Leigh1, Leigh2, Leigh3, Leigh4, Leigh5 and Leigh6 through the client windows operating system in the GUI.
I gave each user account a weak password so it would not take long to crack the passwords.
We then downloaded the file “pwdump7” from tarasco.org and extracted the file to the “C:” drive.
Then we opened the command window and navigated to t...

...ms a master password into complex passwords for different websites the user visits. This means your password is never transmitted or stored on any computer which unlike Last Pass is stored but encrypted.
Report Part Four:
Multi Factor Authentication
Windows Azure Multi-Factor Authentication is a way of reducing risk in organizations and helps to provide an extra layer of authentication. It secures user’s account credentials and provides a safe secure login access for customers and employees. Also this authentication can be used in cloud applications.
It ensures security and helps safeguard access to user data and applications while compiling with user demand for a safe and secure sign-in process.
It has a built in Multi-factor authentication phone call and text message method which verifies its users on sign-in or any payment/transaction methods.
The password related configuration changes which are recommended below will make it more difficult or unauthorized users to figure out user passwords and access systems with the identified
This question marks its way back to the time when people used to rely on the security of windows login credentials. The security no doubt prevented users from having access to one’s personal computer, but once a person had logged into the system, he/she would have the access to basically anything and everything that came their way.
Passphrase is very similar to password, except that it is a longer version of a password, and theoretically is a more secure compared to password (Network Associates, Inc., 1999). It is a secure code created with one or few small word chosen by the user for a security setting (Mitchell, n.d.).
The data breach at Target may have been less brute force than a casual observer might imagine, given the language used on Target’s own FAQ which describes the incident as “criminals forc[ing] their way into our system.”1 While this description might conjure an image of hackers sitting in a dimly lit room, running complex software on super powered machines, and attempting a brute force or DDoS style attack to gain access to customer information databases, the reality appears to have been slightly less glamorous. There can be a variety of unintended entries to a secure system, and criminals will go for the weakest link in the chain. This weak link may oftentimes be not a security hole in the software, but instead the users of that software. The term hacking is used as a catch-all for situations where an information system has been compromised, even though the actual attack or breach of security was nothing more than information leaking out from users or corporations not thoroughly versed in good security practices. In these cases, the breaches are more appropriately described as being a result of social engineering. Social engineering is the technique of combining technological and psychological savvy to obtain illegal access to information2. This can involve anything from complaining and pleading with a phone support representative to give out information, to just realizing that many people use the same password for most of their accounts. Phishing is a social engineering tactic where an attractive, familiar, or official looking email is sent out to multiple recipients with the intent of tricking them into clicking a malicious link or downloading malware attachments3,4. While the latter approach may feel more like hacking, because ...
Hackers are people who are getting into our computer systems, destroying our personal property and stealing our information. Years ago, a hacker was a person who was capable of creating elegant and or unusual uses of technology. These days, a hacker refers to a person who attempts to penetrate security systems on remote computers (Hackers 2). Not only are computer hackers causing many problems for businesses, they are also causing many problems for the average person. Hackers get in personal information and get a hold of credit card numbers, various banking accounts and financial information, and just about anything else they want to know about you. They are going to get it whether you like it or not.
A big responsibility lies on the customers to protect their accounts from getting stolen by thieves. A part of that is using strong and complex passwords and using different passwords for different accounts. But still, the company can play a significant role in helping the customer protect their accounts by requiring minimum criteria for the passwords. For example, the password shouldn’t match the username, it should include letters, numbers and special characters, and it should be at least eight characters. Also, using double authentication methods for processing the purchases would have protected the
Social engineering, the ultimate way to hack password or get the things you want. How most people get into accounts like G-Mail, Yahoo, MySpace, Facebook, or other online accounts. Most people think that hacking a password you need to be computer savvy. This is not the case, those people are crackers. They use custom code or programs to break the passwords. The best way is to use social engineering, I will explain later in the paper why. Before I go any further into this paper, that this information is for research and to increase your knowledge and awareness about security. Also, I hope it will teach you what to watch out for.
The use of hacking to identify weaknesses in computer security has become an increasingly controversial issue in recent years. Awareness of this issue is important, because our ever increasing reliance on technology means that breaches in computer security have the potential to have wide-ranging and devastating consequences to society, worldwide. This essay will begin by clearly defining the term ‘hacking’ and will examine the type of people who hack and for what reasons. There will then follow a discussion of the moral argument on hacking before examining a few brief examples. The essay will then conclude by arguing against the use of hacking as a means of identifying weaknesses in computer security.
Use Different Passwords for Every Online Account This is not just a good tip for Xbox accounts but for web security in general. It might be tempting to use a master password for all your online accounts because it’s convenient, but it’s a good way to get you thoroughly hacked. If you can’t be bothered to remember too many passwords, download a free application like LastPass or KeePass to generate secure passwords and manage them. This way, if you do get compromised, you are not risking important accounts like your email, bank account, Paypal,

if the Username/ Password match fails then, Invalid username/password error message will be propagated to the user to try again.
Second, the current paradigm of rules for password management is outdated and broken. Study after study has revealed that users are not following the rules that security experts have promoted. Decades ago, computer usage was limited and users may have accessed only one or two applications. Enforcement of rules was also more manageable. Users today access dozens, if not
Even though the theft of money is a growing problem, there are other things for hackers to steal. For instance, hospitals have very elaborate network security setups. Why? Many hackers attempt to gain access to people's personal medical files in order to blackmail them, or to avenge some injustice by spreading the person's health problems around. Other possibilities might go as far as to include looking up a patient's current location, in order for gang members to finish off the survivor of a drive-by shooting or other attempted murder. It is for these reasons that medical facilities computer security procedures are second only to the government's (Shoben).
The Art of exploring various security breaches is termed as Hacking.Computer Hackers have been around for so many years. Since the Internet became widely used in the World, We have started to hear more and more about hacking. Only a few Hackers, such as Kevin Mitnick, are well known.In a world of Black and White, it’s easy to describe the typical Hacker. A general outline of a typical Hacker is an Antisocial, Pimple-faced Teenage boy. But the Digital world has many types of Hackers.Hackers are human like the rest of us and are, therefore, unique individuals, so an exact profile is hard to outline.The best broad description of Hackers is that all Hackers aren’t equal. Each Hacker has Motives, Methods and Skills. But some general characteristics can help you understand them. Not all Hackers are Antisocial, PimplefacedTeenagers. Regardless, Hackers are curious about Knowing new things, Brave to take steps and they areoften very Sharp Minded..
