Question

Which type of attack does the use of HMACs protect against?

-DoS
-DDoS
-brute force
-man-in-the-middle

Answer 1

HMACs protect against man-in-the-middle attacks by ensuring data integrity and authenticity. Hackers utilize various methods to acquire sensitive data, which can be prevented using strong security measures and user education. Anti-virus software and proper security practices are essential in reducing hacking risks.

Step-by-step explanation:

HMACs (Hash-based Message Authentication Codes) are used to protect against man-in-the-middle attacks. They ensure that the data has not been altered in transit by providing a way to check the integrity and authenticity of a message. HMACs use a secret key in conjunction with a hash function to create a unique value that can be verified by the recipient using the same secret key.

Hackers employ various tactics such as phishing, malware attacks, exploiting vulnerabilities, and SQL injection, to name a few. They often steal sensitive data like credit card numbers, passwords, or personal information which they can use for identity theft or sell on the black market. To protect against hacking, it is important to use strong, unique passwords, enable two-factor authentication, keep software updated, and be vigilant about suspicious activities and links.

Anti-virus software and firewalls are also important tools in mitigating the risk of hacking. Additionally, educating users about the risks and signs of hacking can reduce the chances of successful attacks. Institutions and individuals must stay informed about the latest security practices to protect their data effectively.

Answer 2

HMACs protect against man-in-the-middle attacks by ensuring data integrity and authenticity. Hackers utilize various tactics to steal sensitive information and may use or sell what they steal. Strengthening security measures can help mitigate the success of hackers.

Thus option 4.man-in-the-middle is correct answer.

Step-by-step explanation:

HMACs, or Hash-based Message Authentication Codes, provide security against a variety of cyber threats, including one particularly insidious form known as man-in-the-middle attacks. In a man-in-the-middle attack, a hacker intercepts communication between two parties, either to steal data or to manipulate the conversation for malicious purposes.

The use of HMACs ensures that the data integrity and authenticity of a message is maintained by using a secret key combined with a hash function. This means that any alteration of the communication can be detected and thus the parties can prevent unauthorized access or tampering.

Hackers use a myriad of tactics, including phishing, malware distribution, and exploiting vulnerabilities. They steal sensitive data such as personal information, financial records, intellectual property, and more.

The stolen data can be used for various illegal activities, including identity theft, financial fraud, or sold on the dark web. Hackers can be quite successful due to persistent security gaps and the evolving nature of their methods.

However, hacking can be reduced or stopped by implementing strong security measures, such as using complex passwords, enabling two-factor authentication, keeping software updated, and educating users about cybersecurity best practices.

Thus option 4.man-in-the-middle is correct answer.
