Fuzz testing or fuzzing is a software/application testing technique used to discover coding errors and security loopholes in software, operating systems, or networks by inputting massive amounts of random data, called fuzz, to the system in an attempt to make it crash.
Fuzzers work best for problems that can cause a program to crash, such as buffer overflow, cross-site scripting, denial of service attacks, format bugs, and SQL injection.
Fuzzer helps to generate and submit a large number of inputs supplied to the application for testing it against the inputs. This will help us to identify the SQL inputs that generate malicious output.
Suppose a pen tester knows the underlying structure of the database used by the application (i.e., name, number of columns, etc.) that she is testing.
Which of the following fuzz testing she will perform where she can supply specific data to the application to discover vulnerabilities?

Attackers create secret accounts and gain illegal access to resources using backdoor while bypassing the authentication procedures. Creating a backdoor is a where an attacker obtains remote access to a computer on a network.
Which of the following techniques do attackers use to create backdoors to covertly gather critical information about a target machine?

SQL injection attacks are becoming significantly more popular amongst hackers and there has been an estimated 69 percent increase of this attack type.
This exploit is used to great effect by the hacking community since it is the primary way to steal sensitive data from web applications. It takes advantage of non-validated input vulnerabilities to pass SQL commands through a web application for execution by a back-end database.
The below diagram shows how attackers launched SQL injection attacks on web applications.

The objective of social engineering pen testing is to test the strength of human factors in a security chain within the organization. It is often used to raise the level of security awareness among employees.
The tester should demonstrate extreme care and professionalism during a social engineering pen test as it might involve legal issues such as violation of privacy and may result in an embarrassing situation for the organization.
Which of the following methods of attempting social engineering is associated with bribing, handing out gifts, and becoming involved in a personal relationship to befriend someone inside the company?

Black-box testing is a method of software testing that examines the functionality of an application
(e.g. what the software does) without peering into its internal structures or workings. Black-box testing is used to detect issues in SQL statements and to detect SQL injection vulnerabilities.
Most commonly, SQL injection vulnerabilities are a result of coding vulnerabilities during the Implementation/Development phase and will likely require code changes.
Pen testers need to perform this testing during the development phase to find and fix the SQL injection vulnerability.
What can a pen tester do to detect input sanitization issues?
