Unit 7 File Encryption Paper

There are numerous reasons to retire our computer technology. Some systems become obsolete due to current technological advances. Some are replaced because they become infected with viruses or otherwise no longer function properly. And others simply just don’t meet the requirements of our business. In order to retire these systems in an efficient, safe and economical manner, we must take into consideration numerous factors that would otherwise but our business at risk. The following policy includes the implementation of recommendations that will keep sensitive information secure

Encryption is the conversion of electronic data into another form, called cipher text, which cannot be easily understood by anyone except authorized parties. The primary purpose of encryption is to protect the confidentiality of digital data stored on computer systems or transmitted via the Internet or other computer networks. Modern encryption algorithms play

Encryption technique is the translation of data into a secret code that will prevent hackers or identity thieves from being able to break or read the data that is sent across the network.

The key can be changes and unique to each sender and receiver. ("Symmetric encryption,”) states, “There are two types of symmetric algorithms. Stream algorithms (Stream ciphers) and Block algorithms (Block ciphers).” Stream ciphers only encrypt one bit at a time. This can make this cipher faster than block ciphers, but stream ciphers have a security gap that can be harmful for specific types of attacks. These specific attacks can cause information to be compromised. Block ciphers encrypts information in blocks instead of doing it bit by bit. The size of the blocks is usually 64 bits. Triple DES and AES are the most popular symmetric algorithms that use block ciphers.

Encryption is a process that turns information that is plainly readable into scrambled form in order to preserve the authenticity, integrity, and privacy of the information that passes through the security perimeter (Michael E. Whitman, 2009). It is the conversion of electronic data into another form, called ciphertext, which cannot be easily understood by anyone except authorized parties (Rouse, 2014).

Encyption takes data and transforms it into unreadable jargon until a key is used to unlock or decrypt the data back to its original form. Due to its near infallibility, encryption is one the most best ways to secure data (Williams & Sawyer, 2015).

Moreover, encryption requires use of a key or cipher, which is used to lock and unlock the hidden data. Such a key is necessary to allow the hidden data to be viewed in an intelligible manner by those who are authorized to view it. However, there is always a risk that the encryption key might fall into the wrong hands, thereby allowing the information to be accessed by unauthorized viewers.

When a fellow general received the message, he would wrap the paper around his corresponding scytale to decipher the message (Tyson 2014). Since the advent of computers though, encryption has become increasing important and relies almost solely on cryptographic means to secure information. When speaking about encryption today, it refers more to the process rather than the mathematical formulas used to scramble data. The basic idea behind encrypting a computer message is such that it is scrambled with a sequence of random bits, known as a key, and only parties with the corresponding key can transpose it back into a comprehensible format. These keys are created via a cipher, otherwise known as an algorithm. When a user sends a message, known as the plaintext, across a network, the computer applies an algorithm to the information to encode it, resulting in a ciphertext (Encryption Basics 2014). This method can be best summarized visually:

To understand encryption, you must place yourself into the internet of the 90’s. At the time the internet was still new, all the data could be seen and accessed easily.The problem was that anyone could access your information and read it. This was a major issue because at that time, internet privacy was almost impossible.

Encryption of data stored on media is used to protect the data from unauthorized access should the media ever be stolen.

Once you could not even dream of putting your credit card on the Internet, but now with the invention of the secure line and encryption capabilities people or now using the internet to buy more than ever. You can now bank online or buy stocks online if you want to, but with all of these new privacy inventions there are always the hackers inventions. Hackers have invaded the privacy of the American Internet User since the dawn of the Internet. With the protection programs that we write, the hackers write their own programs to disregard our individual privacy on the Internet and hack into systems holding our private information and stealing it to reveal some of our most biggest secrets. Encrypting private information has also been a useful tactic against hackers cracking encrypted data, and reading this private information. But they have their own ways of cracking our data. It was only not long ago that we could only encrypt up to 32-bit, and now we can encrypt up to 128-bit which makes it slightly impossible to decrypt unless you have almost all of your life to spend on solving it. But soon hackers will probably write bigger and more complex programs to decrypt this 128-bit shell that we have and make that shell keep on going rising and rising in the numbers until not even a computer program or any hacker can access or private documents or files except us. The war on hackers is

Data or information is the kernel of the modern company. Its availability, integrity and confidentiality are basic to the long-term survival of any 21st-century company. Each company need a complete and scientific method to protect its data, otherwise, the company would be weak in front of risks. These risks are not limited to internet companies. In fact, any company that have secret information have to counter with the risks of data security. In a word, both public and private data could be affected by risks. In UK, almost every company run some external guidance or
