technology security

  1. Logic Testing

  2. Stress Testing

  3. Conformance Testing

  4. Unit Testing

Show answer
Correct Option: D

AI Explanation

To answer this question, you need to understand the concept of different types of testing in software development.

Option A) Logic Testing - This option is incorrect because logic testing refers to the process of testing the logical correctness of the code, typically involving testing the flow of control and data within the code. It does not specifically refer to testing individual methods.

Option B) Stress Testing - This option is incorrect because stress testing is a type of testing that evaluates the system's performance under extreme conditions, such as high user loads or large amounts of data. It is not specifically related to testing individual methods.

Option C) Conformance Testing - This option is incorrect because conformance testing refers to the process of testing whether a product or system adheres to specific standards or specifications. It does not specifically refer to testing individual methods.

Option D) Unit Testing - This option is correct because unit testing is a type of testing that focuses on testing individual units or components of a software system, such as individual methods or functions. It is typically performed by developers to ensure that the individual units of code work correctly in isolation.

The correct answer is D) Unit Testing. This option is correct because unit testing involves testing individual methods in the source code.

Using a custom build process to enable specific features in the Apache Web server is an example of what design principle?
technology security

  1. Least Privilege

  2. Leveraging existing components

  3. Economy of mechanism

  4. Fail safe

Show answer
Correct Option: C

Applying the most restrictive set of operating system permissions to all application files is an example of what design principle?
technology security

  1. Least common mechanism Least privilege

  2. Least Privilege

  3. Separation of duties

  4. Weakest link

Show answer
Correct Option: B
Explanation:

To solve this question, the user needs to know the different design principles used in system design.

The option that represents the design principle described in the question is:

B. Least Privilege

Explanation:

The principle of least privilege is a design principle in which users, agents, or processes are granted only the necessary permissions to perform their assigned tasks, and no more. This principle is important because it limits the potential damage of a security breach or other security incident. By applying the most restrictive set of operating system permissions to all application files, the system is designed to provide each application with the minimum level of access required to function properly, reducing the potential damage that could occur from a security breach.

Option A, Least common mechanism, is a separate design principle that states that the fewer mechanisms shared by users, the less likely those mechanisms are to be compromised.

Option C, Separation of duties, is a design principle that requires that more than one person be involved in a task to ensure that no single individual has complete control over a process.

Option D, Weakest link, is a design principle that states that security is only as strong as its weakest point. It emphasizes the need to identify and address vulnerabilities in a system to ensure that it is secure overall.

Therefore, the correct answer is:

The Answer is: B. Least Privilege

A tool that can perform ODBC commands on a SQL Server

technology security

  1. PSQL

  2. SQLCMD

  3. OSQL

  4. Postgre SQL

Show answer
Correct Option: C

AI Explanation

To answer this question, you need to be familiar with the different tools that can perform ODBC commands on a SQL Server.

Option A) PSQL - PSQL is a command-line tool for interacting with PostgreSQL databases. It is not specifically designed for performing ODBC commands on a SQL Server.

Option B) SQLCMD - SQLCMD is a command-line tool provided by Microsoft for managing and executing SQL Server commands. It supports ODBC connectivity and can be used to perform ODBC commands on a SQL Server. However, it is not the correct answer in this case.

Option C) OSQL - OSQL is a command-line tool provided by Microsoft for managing and executing SQL Server commands. It supports ODBC connectivity and can be used to perform ODBC commands on a SQL Server. This is the correct answer.

Option D) Postgre SQL - Postgre SQL is an open-source relational database management system (RDBMS), similar to SQL Server but not specifically designed for it. It does not provide native support for ODBC commands on a SQL Server.

The correct answer is C) OSQL. This option is correct because OSQL is a command-line tool provided by Microsoft that supports ODBC connectivity and can be used to perform ODBC commands on a SQL Server.

As part of secure coding practices, its one of the counter measure that we take to address specific vulnerablity while attacker sending large amounts of data that exceed the quantities expected by the application within a given field.

technology security

  1. Error handling

  2. SQL Injection attack

  3. Data and Input Validation

  4. Buffer overflow attack

Show answer
Correct Option: D

AI Explanation

To answer this question, you need to understand secure coding practices and common vulnerabilities. Let's go through each option to understand why it is correct or incorrect:

Option A) Error handling - This option is incorrect because error handling is a practice used to manage and handle errors in a program, but it does not specifically address the issue of an attacker sending large amounts of data.

Option B) SQL Injection attack - This option is incorrect because SQL injection is a different type of vulnerability where an attacker can manipulate SQL queries to gain unauthorized access to a database. It is not directly related to the scenario described in the question.

Option C) Data and Input Validation - This option is incorrect because while data and input validation are important secure coding practices, they do not specifically address the issue of an attacker sending large amounts of data.

Option D) Buffer overflow attack - This option is correct because a buffer overflow attack occurs when an attacker sends more data than a program or application can handle, causing it to overwrite adjacent memory areas. This can lead to crashes, data corruption, and even the execution of malicious code.

The correct answer is D) Buffer overflow attack. This option is correct because it directly addresses the specific vulnerability described in the question.
