The seven categories of the expanded CIA triangle are confidentiality, integrity, availability, authentication, accuracy, utility, and possession. I will now go over each and give them a little substance. I used the link provided in the instructor files which was very helpful by the way.
Confidentiality
“Confidentiality ensures that only those with the rights and privileges to access information are able to do so. When unauthorized individuals or systems can view information, confidentiality is breached.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf) “In an organization, the value of confidentiality of information is especially high when it involves personal information about employees, customers, or patients. Individuals who deal with an organization expect that their personal information will remain confidential, whether the organization is a federal agency, such as the Internal Revenue Service, or a business.” ((http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.) This is a concept true in the Army there are two different levels of security clearances for everyone. There is the secret and the top secret each requires a vigorous investigation into a person’s past to make sure they should have the level of clearance they are requesting. If a person doesn’t have at least a secret clearance they are not allowed to access the SIPRnet, which is the Secret Internet Protocol Router Network. This network protocol holds all of the units secure data and can only be accessed by personnel with the proper clearance.
Integrity

“Information has integrity when it is whole, complete, and uncorrupted.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.) “The integrity of information is threatened when the information is exposed to corruption, damage, destruction, or other disruption of its authentic state.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.)
Computer viruses are one way to corrupt the integrity of computer data. File hashing is a way to protect data and assure its integrity. In file hashing “a special algorithm that uses the value of the bits in the file to compute a single large number called a hash value.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.)

Availability

“Availability enables authorized users—persons or computer systems—to access information without interference or obstruction, and to receive it in the required format.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.) This is much like I said back in confidentiality in the military. As long as a user has a Non-Classified Internet Protocol Router Network (NIPRnet) account, they can access NIPR information on the military network.

Authentication “Authenticity of information is the quality or state of being genuine or original, rather than a reproduction or fabrication. Information is authentic when it is in the same state in which it was created, placed, stored, or transferred.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.) E-mail spoofing and Phishing are ways that hackers try to manipulate the authenticity of information in an attack. “E-mail spoofing, the process of sending an e-mail message with a modified field, is a problem for many people today, because often the modified field is the address of the originator. Spoofing the sender’s address can fool the e-mail recipient into thinking that the message is legitimate traffic. In this way, the spoofer can induce e-mail readers into opening e-mail they otherwise might not have opened.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.) Phishing is the act of attempting to acquire information such as usernames, passwords, and credit card details (and sometimes, indirectly, money) by masquerading as a trustworthy entity in an electronic communication.

Accuracy

“Information has accuracy when it is free from mistakes or errors and it has the value that the end user expects.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.) An example of this would be if two people in a clinic have their blood drawn. Both samples go to the lab at the same time, but upon receiving the results the lab techs mislabel the result sheets and misdiagnose two patients. The lab tech’s mislabeling led to the inaccuracy of the test results.

Utility

“The utility of information is the quality or state of having value for some purpose or end.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.) For example the army uses personnel status reports (PERSTATS), in order to learn the status of every soldier in each unit. This status report shows the unit leaders if their soldiers are fully mission capable and able to deploy or if they are not capable of completing simple everyday tasks. This qualifies as utility information because it gives the army vital information on its troops.

Possession

“The possession of information is the quality or state of ownership or control of some object or item.” (http://arapaho.nsuok.edu/~hutchisd/IS_4853/C6572_01.pdf.) The army has stiff guidelines for possession of secret materials. If you are in possession of a secret laptop and you are going to transport it then you must remove the hard drive before doing so, because the computer itself has no secret information it is the hard drive that carries the information. The carrier of the laptop cannot also carry the hard drive there must be a second person to carry the hard drive in case the laptop is lost or stolen that possession of the secret data on the hard drive cannot be easily compromised.
