Which of the following is not a kind of malware? A. Computer Virus B. Computer worm C. Web Phishing D. Keylogger E. Adware When setting up a wireless router at home to enable Wi-Fi access, one can choose a “Wireless Security Protocol” to be used to encrypt the data sent between a computer and the wireless router. Which of the following wireless security protocols is considered the most secure choice? A. None B. WPA2-PSK C. WPA-Enterprise D. WEP
The Correct Answer and Explanation is:
First Question: Which of the following is not a kind of malware?
The correct answer is C. Web Phishing.
Explanation:
- Computer Virus (A): A computer virus is a type of malware that can replicate itself and spread from one computer to another. It often attaches itself to legitimate programs or files, causing damage to systems or stealing sensitive information.
- Computer Worm (B): A worm is a self-replicating piece of malware that spreads through networks without needing to attach itself to a program. It can exploit security holes in the operating system or network services to spread autonomously.
- Web Phishing (C): Web phishing is not technically a malware, but a type of cyberattack in which an attacker tries to deceive users into providing personal information, such as passwords, credit card details, or other sensitive data, by pretending to be a trustworthy entity (such as a bank or email service). It doesn’t involve direct infection of systems but rather social engineering.
- Keylogger (D): A keylogger is a type of malware that records keystrokes on a computer, capturing sensitive information like usernames, passwords, and credit card numbers. It is typically used for malicious purposes, such as stealing credentials.
- Adware (E): Adware is a type of software that displays unwanted ads on a user’s computer. While it’s often less malicious than other forms of malware, it is still considered a form of unwanted software that may compromise user privacy or cause system slowdowns.
Second Question: Which wireless security protocol is considered the most secure choice?
The correct answer is B. WPA2-PSK.
Explanation:
- None (A): This would be the least secure option because not using any encryption would leave the network vulnerable to eavesdropping and unauthorized access.
- WPA2-PSK (B): WPA2 (Wi-Fi Protected Access 2) with a Pre-Shared Key (PSK) is one of the most secure options for home networks. It uses AES (Advanced Encryption Standard) to encrypt the data between the device and the router, providing strong protection against eavesdropping. WPA2 is widely recommended for personal use.
- WPA-Enterprise (C): WPA-Enterprise is a more secure protocol, often used in corporate environments. It requires a RADIUS (Remote Authentication Dial-In User Service) server for user authentication, which makes it more complex but also more secure. However, WPA2-PSK is considered secure enough for most home users.
- WEP (D): WEP (Wired Equivalent Privacy) is an older encryption standard that is considered insecure by today’s standards. It uses weak encryption, making it relatively easy for attackers to break into a network using WEP encryption. WEP is obsolete and should never be used.
Thus, WPA2-PSK is considered the most secure and reliable option for home wireless networks.
