Session Fixation Attack
-
Brute force attack
-
Insecure Direct Object Reference
-
Injection Flaws
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.
-
A scanned copy of a paper certificate document is called a digital certificate
-
Voice signal converted from analog to digital signal during transmission on a PSTN network
-
An encryption mechanism for confirming the message sender and integrity of the message received
-
none of the above
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
This application is for deployment on cloud, so security will entirely be service provider's responsibility and not ours. This is a
-
Absolutely Correct Assumption
-
Absolutely Incorrect assumption
-
Partially Correct Assumption
-
Possibly correct Assumption
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:
| Aspect of Security | Responsibility |
|---|---|
| Physical security of the infrastructure | Cloud provider |
| Network security | Cloud provider |
| Application security | Organization |
| Data security | Organization |
| Compliance with regulations | Organization |
-
It establishes traceability of every action to the doer
-
In some critical situations it should be impossible to deny an action
-
It is a forensic analysis mechanism
-
All of the above
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.

Use of readLine() method in java may lead to
-
Sql Injection attack
-
Denial of Service attack
-
CSRF attack
-
None of these
AI Explanation
To answer this question, it is important to understand the purpose and functionality of the readLine() method in Java.
The readLine() method is used to read a line of text from an input source, such as a file or the console. It returns the line of text as a string. This method is commonly used for user input, where the user can enter text in the console.
However, the readLine() method itself does not directly lead to any security attacks such as SQL Injection, Cross-Site Request Forgery (CSRF), or other similar attacks.
Option A) SQL Injection attack - The readLine() method does not have any direct relation to SQL Injection attacks. SQL Injection attacks occur when an attacker is able to manipulate SQL queries by injecting malicious code into user inputs that are used in SQL statements. To prevent SQL Injection attacks, it is important to use prepared statements or parameterized queries when executing SQL statements.
Option B) Denial of Service (DoS) attack - This is the correct answer. The readLine() method itself does not lead to Denial of Service attacks. However, if the program using the readLine() method does not implement proper input validation and handling, it may be vulnerable to DoS attacks. For example, if the program does not limit the amount of data that can be read using readLine(), an attacker could potentially flood the input source with a large amount of data, causing the program to consume excessive resources and resulting in a denial of service.
Option C) CSRF attack - The readLine() method is not directly related to Cross-Site Request Forgery attacks. CSRF attacks occur when an attacker tricks a user into performing unwanted actions on a website in which the user is authenticated. CSRF attacks exploit the trust that a website has in a user's browser. To prevent CSRF attacks, web applications typically use tokens to verify the authenticity of requests.
Option D) None of these - This option is incorrect, as explained above.
In summary, the readLine() method in Java itself does not lead to SQL Injection or CSRF attacks. However, if proper input validation and handling are not implemented, it may make a program vulnerable to Denial of Service attacks. Therefore, the correct answer is B) Denial of Service attack.
