Group of answer choices.
A) the public key had been compromised.
B) the private key had been compromised.
C) the symmetric encryption key had been compromised.
D) the asymmetric encryption key had been compromised.
Answer:
C) the symmetric encryption key had been compromised.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.
Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Email encryption is the encryption and authentication of an email to protect the message therein from being read by any person other than the intended recipients. Thus, it protects the email from hacking or invasion by a third party.
Basically, when the message is signed with the sender's private key, the receiver can verify its authenticity using the sender's public key.
Also, encrypting the email message with the receiver's public key provides confidentiality.
In this scenario, the most likely explanation for this result is that the symmetric encryption key had been compromised.
While using a Web-based order form, an attacker enters an unusually large value in the Quantity field. The value she entered is so large that it exceeds the maximum value supported by the variable type used to store the quantity in the Web application. This causes the value of the quantity variable to wrap around to the minimum possible value, which is a negative number. As a result, the Web application processes the order as a return instead of a purchase, and the attacker's account is refunded a large sum of money. What type of attack has occurred in this scenario
Answer: integer overflow
Explanation:
The type of attack has occurred in this scenario is a integer overflow. An integer overflow occurs when there's an attempt by an arithmetic operation to create a numeric value which is outside the range which the given numbers are able to represent.
In this, the integer overflow occurs when the result of the integer operation cannot be able to fit in the allocated memory space which then brings about an unexpected result.

Which SCSI standard allows for the technique known as “hot swapping”? Ultra SCSI Original SCSI Serial SCSI Fast-Wide SCSI
Answer:
Serial SCSI
Explanation:
Hot swapping can be defined as a process which typically involves fitting or replacing CD-ROM drive, hard-disk drive, power supply or other peripheral devices while a computer system is powered on. Thus, it allows for the installation or removal of a peripheral device from a computer while power is still being supplied to the computer i.e without having to shutdown the computer.
Serial SCSI is a SCSI standard which allows for the technique known as “hot swapping” because it's a point to point connection that is designed to move data to and from computer storage serially.
