In order to determine whether the character you entered is a letter of the alphabet, you should use this function: C. isalpha ().

<h3>What is a function?</h3>

A function can be defined as a named portion of a block of executable code that is written to perform a specific task, which is usually a single, related action.

This ultimately implies that, a function comprises a group of related statements (executable blocks of code) that would only run and return a data whenever it is called by a software program.

In Computer programming, you should use the isalpha () function to determine whether the character you entered is a letter of the alphabet because it would return a true (a non-zero number), if the argument is a letter of the alphabet.

Classify each of the following acts as a violation of confidentiality, of data integrity, source integrity, or availability, or
AlexFokin [52]

Answer:

A) Violation of Confidentiality and Source Integrity:

Passwords are very confidential information and are usually protected by both the owner and the ower of the system (which in this case is Yahoo). To obtain the passwords, the hacker had to illegally gain access to the source of the data which is on Yahoo servers. Hence a breach of confidentiality and lack of adequate integrity on the part of Yahoo.

B) Source Integrity: Anthony accidentally cuts the electricity from the server room. Why would he be able to do that? how did he gain access into the server room? This speaks to source integrity. People should not be able to access the server room except they are authorised.

C) Source Integrity and Confidentiality: NSA finds an efficient method to break AES. AES refers to the Advanced Encryption Standard. AES is a symmetric encryption technology known as a block cipher.

It is used by the United States Government for the classification of information. Their ability to break this code speaks to Violation of Source Integrity. In this case, they haven't exactly hacked any document. However, any document that was encrypted using this technology is already compromised at the source.

D)   Anna registers the domain name, "JohnSmith" and refuses to let John Smith buy or use the domain name: Violation of Availability.

It is assumed here that John Smith was the original owner of the domain but it was highjacked at expiration and registered by Anna. This kind of breach is called Violation of Availability of the domain name.

E) Some malware encrypts the victim’s hard drive with a secret key and a criminal asks for a ransom to decrypt.

This move is called the Ransomeware attack. The Integrity of the source of information (which is the hard drive) is already compromised. This is a combination of Source Integrity or availability and confidentiality violation.

F) The wiretapping of a cell phone is a breach of confidentiality and data integrity.

G) when there is a vulnerability in a system or software that is unknown to those who should be interested, it is called a Zero-Day vulnerability. Where there is a Zero-Day vulnerability there could be a violation of confidentiality, data integrity, source data and or it's availability.

Cheers!

Anarel [89]

Answer:

Redundancy is the mechanism that occurs in database's data as the same data is stores in the multiple location.It creates repeated data by accident or for backup purpose.

The issues that arise due to the redundancy of the data is the storage space in database gets consumed and thus wastes the space in storing information in multiple locations.When any update occurs in the stored data's field value , it also has to be changed in the multiples occurrences.
