Encryption responses | Information Systems homework help

Provide (2) 150 words response with a minimum of 1 APA references for RESPONSES 1 AND 2 below. Response provided should further discuss the subject or provide more insight. To further understand the response, below is the discussion post that’s discusses the responses. 100% original work and not plagiarized. Must meet deadline.

RESPONSE 1:

The forum post asks us to discuss the role of encryption in ensuring confidentiality. Encryption can be defined as a way of scrambling data so that only the intended or authorized users can understand the data. Encryption requires the use of an encryption key to decipher the data. Encryption makes the data appear like random information or characters to anyone or anything on the outside. This scrambled up data can be referred to as ciphertext and starts out as plaintext then turns into cyphertext in transmission then back to plain text on the receiver end. Data can be encrypted at rest when it is stored, for example on a hard drive or USB stick. It can also be encrypted in transit while being transmitted. To decrypt the data there is a cryptographic key that is a string of characters used withing an encryption algorithm for altering the data to appear random. Encryption acts a lot like a physical lock and key where you need the correct key to lock and unlock the lock. In a way it is a considered a digital deadbolt. Some of the common encryption algorithms are Blowfish, AES, RC4-6, DES, and Twofish. One way of attempting to breach encryption is by a means called brute force attack. A brute force attack works by just making guesses for the correct decryption. These attacks can use millions of guesses in a short amount of time thanks to todays technology, which is why decryption has to be very intricate in todays world. I can’t really comment on this week’s lab yet due to the fact that I have not completed it yet. I will update after I complete the lab. Thanks for reading and take care.

Chris

RESPONSE 2:

In todays age encryptions are very important when it comes to ensuring confidentiality because it has the capability to ensure that only the people that actually have the encryption code are able to see the information instead of just allowing anyone to be able to use the information. This system prevents the unauthorized users from ever accessing such information. With information being so valuable today from that being within companies to just information we may have that could contain such things as our SSN or other private information that we do not need to be taking, information happens to be highly sought after because of the reasons by various cyber criminals that try to take this information for many reasons like opening up accounts in the persons name, wiping out bank accounts, taking information from companies that could be very valuable for the their company or using taking information to demand a request such as trading a certain amount of money for the information. A popular encryption that is considered to be one of the best encryption methods available is AES which is typically used by the government, it typically uses 192 keys and 256 bit for heavy duty encryption purposes .

When it came to this weeks lab it showed us the difference between bit locker and EFS and some of the different ways we would be able to use these while we encrypt files, which would be very helpful in the future considering the need for encryption.
