To answer this question, the user needs to know about common types of attacks on web applications and their characteristics.

Option A: Session Fixation Attack, which is also known as a session hijacking attack, involves an attacker fixing the session identifier of a user to gain unauthorized access to the user's account. This option is incorrect because it does not match the given scenario.

Option B: Brute force attack is the correct answer. A brute force attack is a common type of attack where an automated process tries a large number of possible values to crack a password or find a key. This type of attack is often used to gain unauthorized access to a system or application. This option matches the given scenario.

Option C: Insecure Direct Object Reference is a type of attack where an attacker can access an unauthorized resource by manipulating an object reference. This option is incorrect because it does not match the given scenario.

Option D: Injection Flaws are a type of attack where an attacker sends malicious input to an application to exploit a vulnerability and gain unauthorized access to the system. This option is incorrect because it does not match the given scenario.

Therefore, the correct answer is:

The Answer is: B. Brute force attack.

To solve this question, the user needs to have an understanding of digital certificates.

Option A: This option is incorrect. A digital certificate is not a scanned copy of a paper certificate. A digital certificate is an electronic document that verifies the identity of the certificate holder.

Option B: This option is incorrect. Voice signal conversion from analog to digital signal during transmission on a public switched telephone network (PSTN) is not related to digital certificates.

Option C: This option is correct. A digital certificate is an encryption mechanism that confirms the message sender and integrity of the message received. It contains information about the identity of the certificate holder, including their public key.

Option D: This option is incorrect. Option C is the correct statement.

Therefore, the answer is: C

The answer to this question is C. Partially Correct Assumption.

Explanation:

The cloud provider will take care of the physical security of the infrastructure, such as the data centers and the network. However, the responsibility for application security still lies with the organization that owns the application. This includes things like ensuring that the application is coded securely, that it is properly configured, and that it is regularly updated with security patches.

Therefore, the assumption that security will entirely be the service provider's responsibility is partially correct. The service provider will take care of some aspects of security, but the organization still has a responsibility to ensure the security of their application.

Here is a table that summarizes the different aspects of security that are the responsibility of the cloud provider and the organization:

Non-repudiation is a very desirable trait because it ensures that an action or transaction cannot be denied or disputed by the parties involved. Let's go through each option to understand why it is correct or incorrect:

Option A) It establishes traceability of every action to the doer - This option is correct because non-repudiation ensures that every action can be traced back to the person who performed it. This helps in establishing accountability and responsibility.

Option B) In some critical situations, it should be impossible to deny an action - This option is correct because non-repudiation prevents the ability to deny or dispute an action, especially in critical situations. This is important to ensure trust and reliability in such scenarios.

Option C) It is a forensic analysis mechanism - This option is incorrect. While non-repudiation can be used as a tool in forensic analysis, it is not the primary purpose of non-repudiation. Non-repudiation primarily focuses on preventing denial of actions or transactions.

Option D) All of the above - This option is correct because all the statements mentioned in options A and B are true. Non-repudiation establishes traceability, prevents denial in critical situations, and can be used in forensic analysis.

Therefore, the correct answer is D) All of the above. Non-repudiation is desirable because it establishes traceability, prevents denial in critical situations, and can be used as a forensic analysis mechanism.
