What is cryptography and how is it related to computers?
Cryptography is a means of encrypting or obscuring information. It is related to computers mainly by the internet. When data is passed between a client and a server it can be encrypted so that only the desired recipient can decrypt the data and read it, preventing eaves dropping or interception of the data because the eaves dropper will not be able to decrypt the data (not easily anyway). It can also be used when storing data on a computer - thereby preventing anyone decrypting the data and viewing it.
Does a transaction processing information produce information or data?
is data different from information?
A passive threat to computer security is?
passive threat of a data or information processing system, a threat of disclosureof information without changing the state of the system.For example of a passive threat is one that could result in the recoveryof sensitive information through the unauthorized interception of a data transmission.
How does information differ from data?
Data is just a set of random information without organization - Information is data that is organized in a way to make it useful and actionable.
What are2 examples of data encryption methods?
cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called a cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is information (in cryptography, referred to as ciphertext). The reverse process, i.e., to make the encrypted information readable again, is referred to as decryption (i.e., to make it unencrypted).
Which of these is NOT an example of PII?
Sensitive data on a GFE mobile device does not need to be encrypted.
In which mode of ipsec is the data within an ip packet encrypted while the header information is not?
Transport
What kind of data should be encrypted?
Sensitive data should be encrypted to protect it from unauthorized access. This includes personal identifiable information (PII), financial records, health information, trade secrets, and any data subject to regulatory compliance, such as GDPR or HIPAA. Additionally, data in transit, such as communications over the internet and data stored on devices, should also be encrypted to prevent interception and ensure confidentiality. Encrypting this data helps to mitigate risks associated with data breaches and enhances overall security.
What is another term for encrypted data?
Another term for encrypted data is "ciphertext." Ciphertext refers to data that has been transformed using an encryption algorithm, making it unreadable without the appropriate decryption key. This process helps protect the confidentiality and integrity of the information.
What must be done while sending PII or other sensitive information over a computer?
Make sure the connection being used to send the sensitive infoformation is secured. This can be done probably in several ways. The most common is to have the connection be encrypted. When data is encrypted only the intended computer can un encrypt the data and read it.
Data is encrypted using a single key that only the sender and the receiver know?
By limiting who has access to the data, the information is more secure. Additionally, if the information is compromised, the business can easily determine who did it.
What is the application of encryption?
Cryptography is used to ensure message security during transmission. An example is the use of codes to hide your identity and transaction details when purchasing goods over the internet via you credit card.
Sensitive data on a GFE mobile device does not need to be encrypted?

In the encryption processthe encrypted data is called?
In the encryption process, the encrypted data is called ciphertext. This term refers to the output that results from applying an encryption algorithm to plaintext, which is the original, readable data. Ciphertext is designed to be unreadable without the appropriate decryption key or method, ensuring the confidentiality of the information.
What is encrypted or scrambled data?
Encrypted or scrambled data refers to information that has been transformed using a specific algorithm to make it unreadable to unauthorized users. This process ensures that only individuals with the correct decryption key can access the original content. Encryption is commonly used to protect sensitive information, such as personal data and financial transactions, from unauthorized access and cyber threats.
What does it mean when a customer's credit card information is encrypted?
It means the information is encoded somehow, so if someone unauthorised were to see the data, they wouldn't be able to understand it. Only the authorised systems can decode that data.
Is there a way algorithm to encrypt more numbers in one number and can decrypt?
Yes, there are several algorithms for data compression, that is, store data in less space than it usually needs. However, not all data can be encrypted. Encryption basically takes advantage of some sort of repetition in data; once all repetition has been eliminated, data can be encrypted no more.Yes, there are several algorithms for data compression, that is, store data in less space than it usually needs.
