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.

16. Which of the following is true about function return statements? A) A function can hold multiple return statements, but only one return statement executes in one function call. B) A function can hold only one return statement. C) A function can hold multiple return statements, and multiple return statements can execute in one function call. D) A function can have maximum of two return statements.

Answers

Answer:

A) A function can hold multiple return statements, but only one return statement executes in one function call

Explanation:

This is because each function can only return one value, whether it be an integer, String, or other object.

However, you can have a series of if-else statements, or case statements, to return a different value depending on information (within parameters, or variables.

Excellent. So, you can have multiple return statements, but the function will only end up executing one of these return statements and return a single value.

Hope this helps!

The statement "When there are multiple return statements but one return statement should execute the 1 function call" is true.

The following information should be considered:

This can be done as every function has only a return i.e. one value. It can be an integer, string, or any other thing. The function can't hold only 1 return statement.The function can't hold many return statements that execute one function call. The function can't have the utmost 2 return statements.

Therefore, we can conclude that option A is correct.

why the internet is not policed​

Answers

Answer:

The Internet allows people to circumvent law by committing criminal acts from areas where their activities are not illegal. Those areas will always exist, and thus new regulations will be just as ineffective as the old ones are ["Net Needs Law Enforcement, Author Says,"]. But Internet traffic is marked with IP addresses, and those addresses can be tied to specific networks with specific locations. Shouldn't it be possible to separate traffic based on the originating network and treat data coming from relatively insecure locations differently than data coming from relatively secure locations? It would be much harder for someone in a rogue nation to hack a network if he had to hack an intermediary network first. And unlike government regulation, which has zero impact in areas where these threats are likely to originate, separating traffic by location might actually work

why is computer virus called destructive program​

Answers

Answer:

A computer virus is a malicious software program loaded onto a user’s computer without the user’s knowledge and performs malicious actions.

Viruses which are the most commonly-known form of malware and potentially the most destructive. A virus can do anything from erasing the data on a computer to hijacking a computer to attack other systems, send spam, or host and share illegal content.

Explanation:

The term 'computer virus' was first formally defined by Fred Cohen in 1983. Computer viruses never occur naturally because they are always induced by people. Once created and released, however, their diffusion is not directly under human control. After entering a computer, a virus attaches itself to another program in such a way that execution of the host program triggers the action of the virus simultaneously. It can self-replicate, inserting itself onto other programs or files, infecting them in the process. Not all computer viruses are destructive though. However, most of them perform actions that are malicious in nature, such as destroying data. Some viruses wreak havoc as soon as their code is executed, while others lie dormant until a particular event (as programmed) gets initiated, that causes their code to run in the computer. Viruses spread when the software or documents they get attached to are transferred from one computer to another using a network, a disk, file sharing methods, or through infected email attachments. Some viruses use different stealth strategies to avoid their detection from anti-virus software. Some old viruses make sure that the "last modified" date of a host file stays the same when they infect the file.

Your organization uses the following tape rotation strategy for its backup tapes: The first set of tapes is used for daily backups. At the end of each week, the latest daily backup tape is promoted to the weekly backup tape. At the end of each month, one of the weekly backup tapes is promoted to the monthly backup tape. What kind of backup tape rotation strategy is being used

Answers

Answer:

- Grandfather

Explanation:

In the given scenario, the 'grandfather backup rotation strategy' is employed to have the backup of the audiotape files. This is because the entire process is segregated into three distinct sections; daily backup that keeps the track of all the files recorded every day. It is followed by weekly storage of the audio files after the week wraps up in order to save it for future usage. Lastly, 'monthly' media is backed up in order to ensure that no data is left to be backed up that might be required later. This promotes a quicker, easier, yet complete strategy for backing up the desired data files in the systems. Hence, 'grandfather-son-rotation strategy' is the correct answer.

An attacker gained remote access to a user's computer by exploiting a vulnerability in a piece of software on the device. The attacker sent data that was able to manipulate the return address that is reserved to store expected data. Which vulnerability exploit resulted from the attacker's actions

Answers

"A Buffer overflow" vulnerability exploit resulted from the attacker's actions.

Whenever a software or an application writes too much data into a buffer, causing neighboring storage regions to have been corrupted as a consequence, this could be determined as Buffer overflow.

⇒ There are two kinds of Buffer overflow attacks such as:

Stack-based - It will become more popular to use such memory, as well as that's only available during implementation of any code.Heap-based - Those attacks seem to be more difficult to execute because they entail overflowing overall storage capacity allotted for a program further than the space needed for something like the program's present activities.

Thus we can say that the correct answer is a Buffer overflow.
