What can be the Best Preventive measures against different vulnerabilities?

technology security

  1. Firewall

  2. Input Validation

  3. Updated Antivirus

  4. Extension check for file

Show answer
Correct Option: B

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Firewall - Firewalls help protect against unauthorized access to your network by monitoring and controlling incoming and outgoing network traffic. While firewalls can help prevent certain types of vulnerabilities, they are not the most effective preventive measure against all vulnerabilities. Therefore, this option is incorrect.

Option B) Input Validation - Input validation is the process of checking and validating user input to ensure that it meets specified criteria. By implementing input validation, you can prevent common vulnerabilities such as SQL injection, cross-site scripting (XSS), and command injection. This option is correct because input validation is an effective preventive measure against various vulnerabilities.

Option C) Updated Antivirus - While having an updated antivirus program is essential for protecting against malware and viruses, it is not the most effective preventive measure against all vulnerabilities. Antivirus software primarily focuses on detecting and removing malicious software, but it may not prevent vulnerabilities caused by insecure coding practices or configuration errors. Therefore, this option is incorrect.

Option D) Extension check for file - Checking the extension of a file can help prevent certain types of vulnerabilities, such as file upload vulnerabilities. By validating the file extension, you can ensure that only allowed file types are uploaded, reducing the risk of executing malicious code. However, this measure alone is not sufficient to prevent all vulnerabilities. Therefore, this option is incorrect.

The correct answer is Option B) Input Validation. This option is correct because input validation is a fundamental preventive measure that helps protect against various vulnerabilities.

Which of the following vulnerability can not be handled by Input Validation?

A technique where in a hacker masquerades a fake website to look like the original one to obtain sensitive information from a victim

technology security

  1. Keylogging

  2. Backdoor

  3. Phishing

  4. Masquerading

Show answer
Correct Option: C
Explanation:

To solve this question, the user needs to be familiar with different hacking techniques. The user must identify the technique used by the hacker to obtain sensitive information from a victim.

The correct answer is:

C. Phishing

Explanation:

Phishing is a technique used by hackers to create a fake website or email to look like an original one to trick the victims into providing sensitive information, such as passwords, credit card numbers, or social security numbers. The fake website or email will usually contain a link to the original website, but when the victim clicks on the link, they will be directed to the fake website where the hacker can obtain their sensitive information.

Option A, Keylogging, is a technique used to record the keystrokes of a victim to obtain their login credentials.

Option B, Backdoor, is a technique used to create a hidden entry point to a computer system to gain access to it later.

Option D, Masquerading, is a general term that refers to any technique used to disguise oneself or one's activities.

Therefore, the correct answer is C. Phishing.

Pick Odd One Out :

technology security

  1. AES

  2. DES

  3. RSA

  4. MARS

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the different encryption algorithms.

Option A) AES - AES stands for Advanced Encryption Standard. It is a symmetric encryption algorithm widely used for securing sensitive data. AES is a strong encryption algorithm and is considered to be secure.

Option B) DES - DES stands for Data Encryption Standard. It is a symmetric encryption algorithm that was widely used in the past. However, DES is no longer considered secure due to its small key size.

Option C) RSA - RSA is an asymmetric encryption algorithm named after its inventors, Ron Rivest, Adi Shamir, and Leonard Adleman. RSA is widely used for secure communication and digital signatures. It is based on the mathematical properties of large prime numbers.

Option D) MARS - MARS stands for Multiple-precision Advanced RISC Machine. However, MARS is not an encryption algorithm. It is a type of microprocessor architecture used in computer systems.

The correct answer is B) DES. DES is the odd one out because it is an outdated encryption algorithm that is no longer considered secure. AES, RSA, and MARS are all valid encryption-related terms or algorithms.
