Identify two possible scenarios each under which an active or passive attack can occur to the user or against the owner of the card. Describe how such attacks can be prevented?

Answers

Answer 1

Active and passive attacks can occur against users or owners of a card in various scenarios. To prevent these attacks, it is crucial to implement security measures such as encryption, authentication protocols, and user awareness training.

In the case of active attacks against the user or owner of a card, one possible scenario is phishing. In this scenario, an attacker may send deceptive emails or create fake websites to trick users into revealing their card information or login credentials. Another scenario is a man-in-the-middle attack, where an attacker intercepts the communication between the user and the legitimate card owner, gaining unauthorized access to sensitive information.

To prevent active attacks, users should be cautious when providing personal information online, avoid clicking on suspicious links or downloading attachments from unknown sources, and regularly update their devices and software to patch vulnerabilities.

In terms of passive attacks against the user or card owner, a common scenario is card skimming. In this scenario, attackers install devices on payment terminals or ATMs to capture card details, such as card numbers and PINs, without the user's knowledge. Another scenario is eavesdropping on wireless communication, where attackers intercept and collect sensitive data transmitted over unsecured networks.

To prevent passive attacks, users should be vigilant and inspect payment terminals for any signs of tampering, cover the keypad while entering PINs, and use secure and encrypted Wi-Fi networks whenever possible. Additionally, card issuers and merchants should regularly monitor their payment systems for any suspicious activities and implement security measures such as tamper-proof devices and strong encryption protocols to protect cardholder information.

About the Hubble Space Telescope adapted excerpt from NASA and Space Telescope Science Institute Orbiting 360 miles above Earth, the Hubble Space Telescope is positioned high above the blurring effects of the atmosphere. From this vantage point, it captures images with 10 times the typical clarity of any ground-based telescope and views not only visible light but also wavelengths of near-infrared and ultraviolet light that cannot reach Earth's surface. To operate from orbit, the observatory works like any other scientific or imaging spacecraft; it converts the optical data it collects into electrical signals that are transmitted back to Earth. It must also withstand the airless, high-radiation, and harsh thermal environment of space. Unlike most other spacecraft, however, Hubble was designed to be serviced periodically by astronauts and so was built with modular components that are astronaut-friendly to handle and replace. This design strategy has enabled it to operate longer than ordinary spacecraft and to benefit from the technological advancements of the last two decades. Astronauts have visited the telescope five times to upgrade its computers, mechanisms, and instruments. These servicing missions have kept the observatory at the forefront of discovery by providing it with increasingly sensitive and accurate components. The last of these servicing calls was in May 2009. What is the absolute magnitude of the reduction in the variation of Y when times is introduced into the regression model?
