Security GREAT THINGS ABOUT Passwords IT Essay

In a global where information security is a growing concern, the necessity for user gain access to control is vital to any organization. Authentication is the process that verifies a user's identity and allows appropriate gain access to (Renaud & De Angeli, 135). Authentication may take place by using just what a user knows, what a customer has, or just what a customer is. Verifying a user by what they have got includes the use of your physical device such as keycards or smartcards. The trouble with these is they can be easily stolen or lost. What a customer is means using a unique biometric feature to identify the user. This is actually the most sophisticated type of authentication but also the most invasive and costly. Just what a user knows is typically password authentication, which is the most frequent approach to authentication. The usage of a number of types of authentication strengthens the machine and reduces the prospect of unauthorized gain access to (Hunton et al. 136). However, while the primary reason for authentication systems is to protect organizational assets, systems of authentication must balance security and usability to effectively achieve their goal. This balancing function involves making certain the authentication types of procedures are safe enough to protect the business, but also usable enough in order to not inhibit productivity (Chiasson, 1). There have been an increasing number of hacker attempts to access guarded information, and these disorders have become in sophistication. A business must take steps to guarantee the security of its password authentication system to avoid potential fraud and liability (Leon, 54). Organizations and people rely upon passwords because they are most often the one obstacle between a malicious attacker and a target. Organizations can have entire systems affected if one security password falls in to the hands of your attacker (Shay & Bertino, 1). The ongoing security of any security password authentication system consists of areas such as insurance policies, storage space, and types of passwords.

Security Benefits of Passwords

Knowledge-based authentication using passwords is the most widely-used way for verifying a user's individuality. Passwords are commonly used because they are one of the simplest, and then the least expensive, methods of authentication. With most passwords you don't have for users to have an extra hardware device, so there is absolutely no expense to the organization to purchase such a device. Physical hardware devices could be used by anyone who offers them, so also, they are more prone to being lost or stolen. Passwords systems also do not require considerable hardware or control capacity to run. The authentication systems are easily integrated into an organizational infrastructure (Duncan, 1). Users are aware of how to use passwords to gain access, and so these authentication systems typically do not require considerable training. Passwords can be easily modified if the first is affected, unlike biometric information. Passwords provides huge security benefits to organizations and individuals if integrated with proper insurance policies and procedures.

Good passwords

Using passwords is a simple and effective way to safeguard personal or company information from being taken or made public. However, if the security password is not created properly, then your information is simply hidden rather than very well safeguarded. A bad security password could offer the same amount of security as devoid of one, except to add a few momemts to a hacker's time.

What makes a good password?

The much longer and more technical a password is, the more secure it becomes. Getting a password be considered a name of someone you understand, a pet, a popular place, or a well liked team are all very simple, and could be guessed or cracked easily (Microsoft). However, merely having an extended password is not the most complex way to make one. For instance, if your password were all numbers, then every time you added yet another number to the length of your security password, it would raise the possibilities by ten. This might seem to be secure, as eight individuals would create 100 million possible combos. However, the simplest of personal computers could imagine every likelihood in a bit more when compared to a day. If more than one of these personal computers are used, or especially a whole new home desktop or supercomputer, the results would almost be instantaneous. The best way to have a security password be complex is to include all sorts of characters. In this manner means using not only words, but an assortment of uppercase and lowercase words, numbers, and icons. An eight figure password with all types would increase the options to 7. 2 quadrillion choices. The amount of time it would take to split this sort of password would increase to over 20, 000 years for a simple computer, or 82 times for a super computer (Lucas, 2009). A small business would obviously want to implement this kind of secure password guidelines to protect its information.

How to make good passwords reasonable

There is a tradeoff between getting a secure password and a fairly easy security password (Beyond Par Consulting). Having complicated passwords may cause some forgetful users to write their password down in order to keep in mind it. Doing this defeats the goal of developing a secure password in the first place if an unauthorized end user who wants to access the network were near the password, such as a worker within an adjacent office. Another issue with forgetting more difficult passwords is the fact that one has to work with enough time and sources of the IT staff to help reset or restore the security password. Users need a system or method of remembering their passwords without having to write them down and compromise the organization's property.

An easy way to help users remember their passwords is to have a coding-type system. For example, have an individual pick a phrase that is easy to remember. After the users have their 6-10 word phrase, they can use only the notice at the start or the finish of each term (being regular). The security password will be harder to split since the words will most likely not make a expression, however the consumer will have used a term they know, rendering it easy to keep in mind. The next step is to improve the capitalization of a few letters and add numbers everywhere to the security password. The security password would be filled with symbols (Microsoft). Once the password is complete, the phrase that was used could be on paper, adding some security with some kind of straightforwardness (Breaking Par Consulting). This type of password could still be cracked, however the amount of resources it would take to crack the password could possibly outweigh the advantages of the stolen data. Although a coding system like this one were too impractical, having users simply change the capitalization of certain letters in their passwords, and adding a number will raise the security of passwords and assist in preventing cracking (Almost Networked).

Corporate Security password Policies

While it is important to comprehend the characteristics of a password and why is it strong, it is also important to understand how the degree of password durability and procedures regarding password safety are implemented in the business world. Corporate plans are the methods by which companies train their employees in password management, and these insurance policies can vary greatly between corporate cultures and market sectors. Policies aim to outline companies' targets of their workers, and control buttons regarding those plans can be integrated in many ways. This section covers many of the requirements companies put on password creation and management, as well as provide examples of implementation strategies and corporate insurance policies used today.

First, understand the expectations positioned on companies between industries. To put this concept into perspective, picture the difference in security insurance policies used by a defense contractor who handles confidential information and someone running a "mom and pop" store that markets leather saddles and chocolate. Obviously, you'll expect the security contractor to possess tighter security and protection encircling its information. These same security safeguards carry over into the creation, execution, and management of security password procedures as well. To demonstrate, a Goldman Sachs employee must change his / her password once a month, and likewise incorporate in the password uppercase and lowercase alpha keys, at least one quantity, one special persona, and a minimum of 8 characters in length; whereas a catalogue policy aquired online required only 6 characters long with any mixture of letters, symbols, and statistics (Marshall, Ben; CNSSL, Sample Password Coverage).

Creation

With security objectives in mind, a firm then begins to create its policy. Test policies that are available to anyone for free can be found through organizations like the SANS Institute. These sample policies illustrate how a policy contains portions for the analysis, purpose, and scope of the coverage, as well as the actual standards and recommendations applicable to employees (SANS). Companies may use outlines like these examples in helping these to script or adapt their insurance policies to make them more applicable with their company and industry. This section will preview three common procedures commonly employed by companies in their security password policies.

Periodical Security password Changes: corporate insurance policies often format requirements for employees to improve their passwords over a periodic basis. This necessity is a common standard among regulations today, as it restricts the likelihood that the worker can use the same security password for other applications or has given an unauthorized user the methods to enter the machine for an extended period of the time. There can be different time requirements for changes between passwords; for example, a business may require its employees to improve their system-level passwords double per year while only requiring the user-level password one per year. A policy like this one would highlight the amount of security put on the server-level password above the user-level one. Certainly, the length of time between required changes can vary greatly between companies predicated on the amount of security they expect to maintain. Some companies even require their workers to improve their passwords as often as monthly (Marshall, Ben)!

Password Contents: as mentioned above, using different heroes is a common tactic recommended in every password coverage that places increased security on the structure of passwords. Different personas often required in many procedures include: lowercase characters, uppercase characters, volumes, punctuation and "special" personas such as symbols.

Password Protection: insurance policies can cover safeguard issues from how passwords are to be stored through sophisticated encryption procedures, to how employees are to protect their passwords by not writing them on their computer screen. In fact, a common corporate policy is the fact that employees aren't to create their password everywhere. Companies often store consumer labels and passwords in a secure place for employees should they forget them. Storing these passwords can be an work to deter users from making their security password available anywhere.

Implementation

When putting into action a password insurance plan, managers must foresee the way the employees will react to the guidelines. Will they think the new insurance plan is an unneeded nuisance? Will they think the coverage is too hazy or too restrictive? In detailing the plan, employers must be certain that employees understand the repercussions for breaking the insurance policy, which can vary between companies. For example, when working with labeled information, negligence in upholding security password regulations is a criminal offense. However, this "scare tactic" of aiming to enforce a policy may not be as effective as substitute methods. Instead, some managers believe it is more helpful to stress the importance of password security, not the implications of breaking insurance policy rules (Wikipedia).

Even with the insurance policy in place and training completed, it is still very hard to measure whether users are following the policies set forth, as many of them can be difficult to identify, such as not writing passwords on post-it records. Therefore, companies must understand the value of training employees in their security policies to the same level they coach employees in other safety and HR regulations at the beginning of, and often throughout, the employees' professions (Password Policy, Wikipedia). The need for this training can't be stressed enough, as it concerns the security of an organization. For example, the required minimum password durability can be as high as is practicable, but any work will be fruitless if an employee tells another person the password, or perhaps sends it unencrypted over a contact. Therefore, the execution and enforcement of policies are crucial to keeping company and staff information safe.

Maintenance of passwords

An issue that companies come across when implementing tight password procedures, like requiring intricate or designated passwords that are difficult to remember, is that folks often write them down on things like post-it notes or anywhere near their computer. In order to prevent employees from writing their passwords down, companies also have provided literally- and logically-secure places, like a fire-safe or encrypted document only available to underlying users, where staff passwords are stored (CNSSL, Sample Password Policy; Password Insurance policy, Wikipedia).

These "safe-houses" for passwords, as discussed above, will come in many varieties. The first exemplory case of utilizing a fire-safe to store employee and company passwords is somewhat outdated in keeping practice. Instead, companies turn to password furniture, teeming with encryption options, to safely store passwords and keep data safe (Leon, 55). Password tables in essence store user labels and passwords and match those to the values joined by users attempting to enter the machine (Leon, 55). While in this databases, administrators must ensure that the user data is stored safely, using hashing methods to guard against unauthorized use. "Basic hash encryption" can be an approach to hashing where information is coded using a method that encodes an individual data into a value that is unusable to anyone who views it (Leon, 55). However, basic hashing often does not give enough security to protect against proficient hackers. Nowadays, hackers employ such tools as "rainbow furniture" to try and match encrypted data to pre-made hashes of almost every possible password (Gates, Chris). To safeguard this information even further, companies may utilize "salt hashing, " which attaches a "random selection of individuals" to a user's security password before implementing the essential hash encryption (Leon, 55); this form of encryption is exponentially more challenging for a hacker to crack, and will often deter him/her from even attempting to gain entry into the system.

Sometimes, varying power degrees of passwords may be employed to different security degrees of information as well. For example, pass codes to firm-wide resources like your kitchen will be the same password for everybody and may be very short, whereas admittance to a study lab might require a far more unique and sophisticated code. This example is a simple one, but it illustrates how a company may use a universal password to prevent employees from using one security password for everything. It also illustrates how not all areas requires authentication have to have the same degree of security.

Finally, having a solid security password and strong security regulating the storage area of passwords, will not ensure complete security. The ultimate level of security password security rests with users. There are always a multitude of risks to even the soundest passwords, and thus it's important that organizations create and teach their workers in the necessary policies to avoid threats from triggering damage.

Cracks

The notion of a security password is to avoid unauthorized users from being able to access a secure area. So how do unauthorized users still manage to get access? A method is to simply "crack" the authorized user's security password, allowing the assailant to access the system as if she or he were the approved user in the first place. There are a variety of password-cracking programs that use a variety of cracking methods. Two fairly-related ways to crack a password will be the brute make method and the dictionary assault method.

Brute force method

The brute pressure method is the easiest of most cracking methods, which means that it also needs the longest to accomplish its goal. If an unauthorized customer attempts to find another user's security password through brute push, she or he will use a program to suppose the password using every possible combination of characters available. For example, if the security password plan requires all passwords to be 6 characters long and entirely composed of numbers, then there would be 10^6 possible combos of passwords. The cracker's program would use every single combination in that pool of possible combos until it gained access to the system. The Cain and Abel password-cracking program bought at Oxid. it, and used in our demonstration, may be used to execute a brute force assault. (Oxid. it)

As the complexity of your password increases, the amount of possible mixtures also raises. Thus, the best way to prevent a brute drive method from being successful is to simply make a password more complex. For example, instead of demanding a security password to be made up solely of numbers, maybe it's necessary to have an assortment of letters and numbers. This solution would increase the variety of possible combinations to 36^6, assuming the password duration remained the same. A lot more complexness that is put into a password, the longer it will take for the cracker to gain access.

Dictionary episode method

Similar to the brute force method is the dictionary assault method. Essentially, it's the identical to the brute push method, but tweaked in order to lessen time. Executing a dictionary harm on something is precisely what it appears like: attacking a system through the use of a dictionary, or rather the words found in a dictionary. A dictionary invasion attempts to imagine a user's security password by trying a large number of common words that will tend to be found in an average dictionary. Relating to Imperva, about "50% of users used brands, slang words, dictionary words or trivial passwords" to protect their most personal information (Imperva). Thus, someone by using a fairly-comprehensive dictionary -- the one which consists of slang, common names, and normal words within a dictionary -- as the only real list of passwords to imagine, would have a very high potential for accessing most users' data. Restricting the pool of possible guesses would greatly decrease the time expected to successfully crack another user's password.

Defenses against a dictionary assault would be the same as defenses against a brute pressure attack. Simply altering the password such that it is not an easily-recognized word exponentially increases the estimated a chance to crack it.

Software and hardware

While password-cracking is a simple way to grab someone's password, setting up software or hardware on the target's device is a easier way to get their information. Keystroke loggers and packet sniffers are two very powerful tools that someone may use.

Keystroke loggers

Keystroke loggers are programs and devices that record the precise sequence of tips a consumer performs. They could be software that is installed on a user's device (either intentionally by the hacker or unwittingly by the prospective, via Trojan horses malware). While one might think that installing hardware on a target's computer would be easily found out, a hardware keystroke logger is mounted on the back of a computer, where it is less likely to be seen (Keyghost). Other, more sophisticated hardware keystroke loggers can in fact be installed straight into the keyboard, therefore the only way to find them would require a user to actively search for one.

Either way, the keystroke logger records a user's actions in a log record, and that document can be seen on by anyone who has learned how to locate it. An unethical person could flick through the log record to check out usernames and then start to see the characters selected later on, as these character types would most likely be the password.

Packet sniffers

Another solution to steal a user's password through either software or hardware is by using a packet sniffer. Packet sniffers record data that is being transferred across a network. Unless the info is encrypted, an individual of the packet sniffer can see the info in plaintext, so that it is very easy to get the username and password. Even if the info is encrypted, however, you may still find other ways for the user to decrypt or crack it, as specified above.

Defending against these procedures of attack is a lot more challenging than defending against a password-cracker. To prevent keystroke loggers and packet sniffers from being downloaded onto a user's device, a business should establish guidelines concerning what an employee can and cannot download. So far as hardware can be involved, physical security and regulations should be instated to ensure that really the only individual with access to an important device is the main one with authorization.

Scams

One more way for criminals to take users' information is, of course, to scam the user. Scams have been around permanently, and the surge of the web has only allowed them to become more sophisticated. Most people are alert to the Nigerian advance-fee fraudulence, where a potential victim obtains an email indicating that he or she has been given an possibility to help out someone else in return for a multi-million buck reward. All of the person needs to do is provide bank-account information. This type of con is common, and has changed to become less immediately-recognizable as a con. For example, emails today often "spoof" a known organization. This spoofing can be carried out by altering the email contents such that it looks recognized (, somewhat than, for example). The targeted user may not recognize that the email is fraudulent, and may unwittingly hand over personal account information.

According to Miller Smiles, "the web's dedicated anti-phishing service, " corporations such as lenders will never request personal information through email. If someone is uncertain whether a contact is fraudulent or not, Miller Smiles consists of an archive of deceptive emails that folks can browse through to see if their e-mail have been completely found to be deceptive. In addition, before taking these emails as genuine, the web site also implies forwarding the email to the real institution it purports to be from, requesting if it was dispatched following that. (Miller Smiles)

Alternative Types of Passwords

Many of the vulnerabilities found with static-text based passwords can be resolved without significant investment in new authentication systems. The use of visual or one-time passwords have proven to be more secure and user friendly than traditional security password authentication systems.

Graphical Passwords

Graphical passwords derive from the ability to recognize pictures rather than text. There are three types of picture-password systems; searchmetric, locimetric, and drawmetric. Searchmeteric systems entail the user choosing a mixture of images from an issue set. Whenever a individual uses Locimetric systems they select a group of positions within one image. Drawmetric systems require an individual to sketch out a distinctive pattern, and act like biometric authentication that uses personal or handwriting acknowledgement. Typically, users are able to choose their own images to assist in keeping in mind the security password. Graphical passwords are more secure and user-friendly than regular passwords. Because images are more difficult to mention or write down then wording and numbers, these are less vunerable to being jeopardized. Research shows that humans have the ability to remember images more accurately and for an extended time period than text message, thus users are less likely to ignore image passwords (Renaud & De Angeli, 136-139).

One-Time Passwords

One-time passwords also mitigate a few of the security risks of regular passwords. With this type of authentication the security password is different each and every time a end user logs on to the system. While using time-synchronized and counter-synchronized method, the user must possess a physical device to get the one-time password. This device, often called a "token", is connected to a server that runs on the complex algorithm to set-up the passwords. This algorithm makes it problematic for hackers to speculate the correct security password (Griffin, 2). While the token eliminates the necessity for an individual to remember an elaborate security password, it also adds cost and difficulty to simple password authentication. A token gets the potential to be misplaced or taken from an individual. The ability to have a token-less one-time password system has surfaced with new software. These passwords are usually delivered after a user answers a couple of questions and are establish by an alternative solution secure means such as encrypted email or text message (Yudkin, 1).

Conclusion

Information security is vital for organizations and people to attain their respective goals. Passwords are an extremely easy and functional way to secure informational resources and systems. You will find alternative ways of security, but none of them are as user friendly as passwords. Passwords security systems are also the least expensive to implement of all authentication methods. The commonality of passwords makes it vulnerable to a variety of threats including password crackers, malicious software and scams. Thus, to ensure that passwords are not a inadequate security measure, proper password recommendations and policies are necessary.
