This computing technology is used in newer debit and credit cards to process transactions. Select one: a. RFID chips. b. magnetic strips. c. QR codes.
Answers
The computing technology that is used in newer debit and credit cards to process transactions is RFID chips. Therefore, option (a) RFID chips is the correct answer.
What is RFID?Radio-frequency identification (RFID) is a technology that uses radio waves to automatically identify and track tags attached to objects. Tags contain electronically stored information and are used for various purposes, including inventory management, tracking assets, and security authentication.
In debit and credit cards, RFID chips use electromagnetic fields to communicate with card readers. When the card is held near an RFID reader, the reader sends a signal to the RFID chip, which then uses the energy from the signal to transmit the card's information wirelessly back to the reader.
This process is faster and more secure than traditional magnetic strip technology and helps to prevent fraud.
So, the correct answer is A

List at least three security design principles that should be used in secure software design.
For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
Answers
Secure software design principles are crucial for ensuring that software systems are protected from malicious attacks. Here are three security design principles that should be used in secure software design: Least privilege; Defense in depth; Fail-safe defaults.
1. Least privilege: The principle of least privilege states that users should only be given the minimum access necessary to perform their tasks. This means that software systems should be designed to limit access to sensitive data and functionality, and that users should only be given access to what they need to do their jobs.
2. Defense in depth: Defense in depth is a principle that involves layering security measures to create multiple lines of defense against attackers. This means that software systems should be designed to include multiple security controls, such as firewalls, intrusion detection systems, and encryption, to protect against different types of attacks.
3. Fail-safe defaults: Fail-safe defaults are settings that are designed to protect the system in the event of a failure. For example, software systems should be designed to default to the most secure settings possible, such as disabling unused services and features, to prevent attackers from exploiting vulnerabilities.
By following these security design principles, software developers can create systems that are more resilient to attack and better able to protect sensitive data and resources.

Your ghost hunting group is recording the sound inside a haunted Stanford classroom for 20 hours as MP3 audio files. About how much data will that be, expressed in GB
Answers
Answer:
1.152 GB if it will be at 128 kbps quality
Explanation:
So, let's say you choose your mp3 be 128 kbps (kilobits per second).
One byte is 8 bits. So 128 kbps = 16 kilobytes per second.
There is 60*60 seconds in one hour. So 16*60*60 = 57.6 megabytes per hour
Multiply by 20 hours to get your answer: 57.6*20 = 1152 MB = 1.152 GB.
20 hours as MP3 audio files would be about 1.2 GB of data
MP3 audio uses about 1 MB per minute.
20 hours = 60 minutes/hour * 20 hours = 1200 minutes.
Since MP3 audio uses about 1 MB per minute, hence for 1200 minutes:
1200 minutes = 1200 minutes * 1 MB per minute = 1200 MB (1.2 GB)
20 hours as MP3 audio files would be about 1.2 GB of data

T/F: Email spoofing rarely is used in virus hoaxes and spam.
Answers
False. Email spoofing is actually a common tactic used in both virus hoaxes and spam. Email spoofing involves disguising the sender's email address to make it appear as if it is coming from a different source.
This can be done to trick recipients into opening an email or clicking on a link, leading them to unknowingly download a virus or malicious software. In the case of virus hoaxes, email spoofing may be used to give the impression that the email is coming from a trusted source, such as a well-known company or government agency. The email may contain false information about a supposed virus outbreak or security threat, prompting the recipient to take action, such as forwarding the email to others or downloading a supposed "antivirus" software. Similarly, email spoofing is also commonly used in spam emails, where the sender may pose as a reputable company or individual in an attempt to gain the recipient's trust and persuade them to click on a link or download an attachment.
Overall, email spoofing is a deceptive tactic that can be used for a variety of malicious purposes, including virus hoaxes and spam. It is important for individuals to be cautious and verify the authenticity of emails before taking any action.

Thus, hash values are an essential tool in ensuring the integrity of data. They allow for the verification of data integrity by comparing hash values before and after the transfer of files.
Comparing hash values can be used to assure that files retain integrity when they are moved from place to place and have not been altered or corrupted. Hash values are unique identifiers that are generated by a mathematical algorithm.
These identifiers are based on the contents of a file, and any change to the file will result in a different hash value. By comparing the hash value of a file before and after it is moved or transferred, one can ensure that the file has not been tampered with or corrupted during the process.Integrity is a critical aspect of data security. Without data integrity, files can be altered, deleted, or corrupted without detection, leading to significant consequences. Hash values are an essential tool in ensuring the integrity of data. They provide a way to verify that data has not been tampered with or altered, making them an important part of any security protocol.In conclusion, hash values are an essential tool in ensuring the integrity of data.
