Understanding your strengths, vulnerabilities, and where your team should allocate time is crucial in the realm of cybersecurity. However, determining these factors and prioritizing tasks can be challenging. So, conducting penetration testing is a highly effective approach to gaining clarity.

Penetration testing is a solid basis for any security team. It excels at pinpointing what to focus on and proposing initiatives for your team’s future endeavors. So, what exactly is pen testing, and why is it so important? The following article will provide further insights.

What is Penetration Testing?

A penetration test (or pentest), is a sanctioned simulation of an attack carried out on a computer system to assess its security. Penetration testers employ identical tools, methods, and procedures as actual attackers to discover and illustrate the detrimental effects of system vulnerabilities.

These tests typically simulate diverse attack types that pose potential risks to a business. They evaluate the system’s ability to resist attacks from authorized and unauthorized sources, as well as various system roles. With appropriate parameters, a pen test can delve into any system facet.

Why is Penetration Testing Important?

A penetration test holds a strong significance in ensuring network security. This testing methodology enables businesses to accomplish the following objectives:

• Uncover security vulnerabilities preemptively, beating hackers to the punch.
• Identify gaps in information security compliance.
• Assess the response time of the information security team, gauging how quickly  to detect breaches and minimize the impact.
• Understand the potential real-world consequences of a data breach or cyber attack.
• Obtain actionable guidance for remediation purposes.

Penetration testing empowers security experts to methodically assess the security of multi-tier network architectures, custom applications, web services, and other IT components.

Penatration testing services and tools provide swift visibility into high-risk areas, letting businesses build security budgeting.

Comprehensive testing of an organization’s entire IT system, a web app or a mobile app is crucial for safeguarding critical data from cyber hackers and enhancing the IT department’s responsiveness during potential attacks.

5 Phases of Penetration Testing

Penetration testers replicate the tactics employed by determined adversaries. At LQA, we adhere to a comprehensive plan that encompasses the following penetration testing process:

Phase 1 – Estimation

In the first pen testing process, we need to understand the exact number of items in scope, such as

• HTTP requests in web application and API,
• screens & main functions in Android / iOS application,
• server and network devices,
• IP addresses in systems.

Then, we build a plan based on the function severity. The ranking on a scale of A to S will be used as a criterion for customers to select items to test from the estimate list.

Phase 2 – Preparation

In this phase, we need to prepare some things before testing, including:

• Web application information: Site name, host, system, cloud services, penetration testing type (remote, onsite), period time, environment testing.
• Access restriction: Restricting access with IP address, basic authentication, we also need some special configured access settings.
• Account information: Multiple permission settings, multiple accounts (username and password).
• Various process: Assessment of functions associated with various processes and external systems.
• Validation: Confirm other important information before testing.

Phase 3 – Penetration testing

In this phase, LQA’s testing team will:

• Schedule penetration testing
• Implement manual and automated testing
• Analyze and evaluate detected vulnerability
• Analyze and evaluate the case of threats and impacts when the vulnerability is exploited

Phase 4 – Report

In the report phase, we will:

• Send daily quick report for high-risk vulnerability detected.
• Write a summary and technical report, then deliver the final report.

Phase 5 – Re-testing

In the last phase, LQA’s testing team will re-test the vulnerabilities after remediating programs.

After completing a successful pen-test, an ethical hacker collaborates with the target organization’s information security team to share their findings.

Typically, these findings are categorized with severity ratings, enabling the prioritization of remediation efforts. Issues with the highest ratings are addressed first to ensure effective resolution.

A business uses these findings as a foundation for conducting additional investigations, assessments, and remediation to enhance its security posture.

At this stage, decision-makers and stakeholders become actively involved, and the IT or security team establishes deadlines to ensure prompt resolution of all identified security issues.

Pen Testing Approaches

Penetration testing includes a trio of primary approaches, each equipping pen testers with specific levels of information required to execute their attacks effectively.

• White box testing: In white box testing, the customer furnishes comprehensive system information, including accounts at various access levels. This ensures that the testing expert can band encompass system’s functionalities.
• Black box testing: Black box penetration testing is a form of behavioral and functional testing in which testers are intentionally kept unaware of the system’s inner workings. Organizations commonly engage ethical hackers for black box testing, as it simulates real-world attacks and provides insights into the system’s vulnerabilities.
• Gray box testing: Gray box testing combines white box and black box testing techniques. Testers are granted limited knowledge of the system, including low-level credentials, logical flow charts, and network maps. The primary objective of gray box testing is to identify potential code and functionality issues in the system.

Application testing can be classified in various ways, encompassing methods, levels, techniques, and types. To gain a comprehensive and clear understanding of the application testing system, take a look at the infographic below.

Types of testing

Application Testing Methods

There are two primary application testing methods: Manual Testing and Automation Testing. Let’s explore the key differences between Manual Testing vs Automation Testing, and understand when to use each method effectively.

Manual testing

This testing method involves human QA engineers and testers manually interacting with the software app to evaluate its functions (from writing to executing test cases).

In manual testing, QA analysts carry out tests one by one in an individual manner to identify bugs, glitches, defects, and key feature issues before the software application’s launch. As part of this process, test cases and summary error reports are developed without any automation tools.

Manual testing is often implemented in the first stage of the SDLC to test individual features, run ad-hoc testing, and assess one-time testing scenarios. 

It is the most useful for exploratory testing, UI testing, and initial testing phases when detecting usability issues and user experience problems.

Automation testing

This testing method utilizes tools and test scripts to automate testing efforts. In other words, specified and customized tools are implemented in the automation testing process instead of solely manual forces.

It is efficient for repetitive tests, regression testing, and performance testing. Automation testing can accelerate testing cycles, improve accuracy, and ensure consistent test coverage across multiple environments.

Manual Test and Automation Test

Application Testing Techniques

Black box testing

Black box testing is a software application testing technique in which testers understand what the software product is supposed to do but are unaware of its internal code structure.

Black box testing can be used for both functional and non-functional testing at multiple levels of software tests, including unit, integration, system, and acceptance. Its primary goal is to assess the software’s functionality, identify mistakes, and guarantee that it satisfies specified requirements.

White box testing

White box testing, or structural or code-based testing, is the process of reviewing an application’s internal code and logic. 

Testers use code coverage metrics and path coverage strategies to ensure thorough testing of code branches and functionalities. It is effective for unit testing, integration testing, and code quality assessment.

Gray box testing

Gray box testing is a software application testing technique in which testers have a limited understanding of an application’s internal workings.

The principal goal of gray box testing is to combine the benefits of black box testing and white box testing to assess the software product from a user perspective and enhance its overall user acceptance. It is beneficial for integration testing, usability testing, and system testing.

Black box, Grey box and White box penetration testing differences

• Realistic evaluation: Black box testers focus on the output of the software application and how the software works in reality.
• User focus: Black box testers evaluate software functionality as users, from a user perspective, hence increasing the likelihood of user acceptance.
• Early testing: Black box test cases can be designed right after the completion of specifications and executed in the early stages of software development, allowing for early detection of functional issues.
• Unbiased tests: Black box testers provide an unbiased, fresh perspective as they lack knowledge of the internal workings of the app.

Cons of black box testing

Black box testing also has some drawbacks, such as:

• Dependence on documentation: Black box testing test case design relies heavily on accurate and comprehensive specifications, which may not always be available or up-to-date.
• Limited code coverage: Black box testing may miss certain code paths and internal logic, reducing the depth of testing coverage.
• Inefficiency for complex systems: It may not effectively pinpoint intricate code-related issues in complex software architectures, due to its inability to directly access and analyze the internal code structure.
• Potential for redundancy: Tests can be redundant if already run by the software designer and developers.

Types of Black Box Testing

Black box testing is applied to 3 major test types: functional testing, non-functional testing, and regression testing.

Functional testing

Functional testing ensures that the software functions as intended. It tests features like input validation, user interface, and data manipulation.

Some common types of functional testing include smoke testing, sanity testing, integration testing, system testing, and regression testing.

Black box testing in functional testing involves creating test cases based on external specifications, executing them to validate functionality, and ensuring that the software meets specified requirements without knowing the internal code.

Non-functional testing

Non-functional testing focuses on aspects other than functionality, including performance, security, usability, and reliability.

In other words, while functional testing checks if the software performs a specific action, non-functional testing checks how the software performs that action under different conditions.

In non-functional testing, black box tests can assess whether the software:

• is user-friendly
• performs well under various loads
• is compatible with different browsers, devices, and environments
• remains secure against common threats and vulnerabilities

Regression testing

Testers can use black box testing techniques in regression tests to verify whether new changes affect the existing functioning of the system.

Regression testing is often done when there are modifications to a system, such as developing a new function, fixing a bug, or maintenance. In apps with frequent updates, regression testing is often automated for optimal efficiency.

Black Box Testing Techniques

There are many black box testing techniques that apply to different logics within software applications. Here are the 5 major techniques.

All the above black box testing methods can be done without knowing the internal workings of the system, hence are called black box testing. Let’s dig into them!

1. Boundary value analysis (BVA)

Boundary value analysis, short for BVA, is a black-box testing technique to test the boundaries between partitions instead of testing multiple values in the equivalence region. In BVA, testers assume that if it is true for boundary values, it is true for the whole equivalence region.

Example of BVA: 

Let’s say you’re testing a system where valid age values are between 20 and 50.

• Test with the minimum boundary value (20). It should be valid.
• Test with the maximum boundary value (50). It should be valid.
• Test just below the lower boundary (19). It should be invalid.
• Test just above the upper boundary (51). It should be invalid.

2. Equivalence class partitioning

In equivalence class partitioning, also known as equivalent partitioning, testers divide all possible inputs into various equivalence data classes (or data groups) and test only one example input from each class, assuming that data in each class behaves the same.

Example of equivalent partitioning:

Imagine you’re testing a system where valid usernames are within 5 – 20 text-only characters. You divide the inputs into 5 groups as below.

Then, you pick one representative input from each group to test. For instance, if you input 10 text characters, it should be valid. But if you input 4 characters, it should be invalid.

3. Decision table based testing

Decision table, also called a cause-effect table, is a software testing technique based on cause-effect relationships. It is used to test system behavior in which the output depends on a combination of inputs, for instance:

• Combination of inputs: all blanks/specific blanks in the log-in section are filled in by a user.
• System behavior: navigate the user to the homepage.

Example of decision table testing: 

An app allows users to log in only when the username, password, and captcha are correct. We have the below table that represents all possible scenarios to test, in which T = true and F = false.

4. State transition testing

In state transition black-box testing, changes in the input make changes to the state of the system and trigger different outputs. In this technique, testers execute valid and invalid cases belonging to a sequence of events to evaluate the system’s behavior.

Example of state transition testing: 

An e-commerce app will lock a user’s account if he/she enters the wrong password 3 times in a row. This means the user will be able to log in if he/she enters the correct password on the 1st, 2nd, 3rd try. Each time the password is entered correctly, the state is transitioned into “Access accepted”. Otherwise, the state turns into “Account locked” after the 3rd time entering the wrong password.

The state transition diagram below represents a sequence of events to test.

5. Error guessing

In error guessing, you rely on testers’ intuition and experience to anticipate and uncover possible errors or error-prone situations in the software, particularly in situations where formal test cases may be insufficient.

In error guessing, the test cases could be based on:

• Previous experience in testing related/similar software products.
• Understanding of the system to be tested.
• Knowledge of common errors in such applications.
• Prioritized functions in the requirement specification documents (to not miss them).

Black Box vs. White Box vs. Gray Box Testing

Black box, white box, and grey box testing make up the three software testing methodologies to test an app as an outsider, an insider, and a partial insider. While black box testing and white box testing are opposite concepts, gray box testing stands in between the two.

Let’s dive into a detailed comparison between black box, white box and gray box testing.

How To Perform Black Box Testing?

A standard black box testing process takes place as below:

• Examine the requirements and specifications of the software
• Define the testing scope, objectives, and create a test plan
• Develop test cases based on specifications and user scenarios, including choosing valid inputs, invalid inputs, and expected output for each input.
• Execute the test cases, entering inputs, observing outputs, and comparing real outputs with expected outputs.
• Document any discrepancies or defects found during testing.
• Re-run tests after fixes or changes to ensure existing functionality remains intact.

Frequently Asked Questions about Black Box Testing

1. What are the types of black box testing?

Black box testing is suitable for three primary types of tests: functional testing, non-functional testing, and regression testing.

2. Is black box testing illegal?

No, black box testing is not illegal. It is a legitimate and widely used software testing method where testers assess the functionality of a system without knowing its internal code.

However, it’s crucial to conduct black box testing on systems you have permission to test, respecting ethical and legal boundaries. Unauthorized testing on systems or networks without proper consent is considered illegal and can result in legal consequences.

3. Why might companies prefer black box testing over white box testing?

Black box testing is user-focused and doesn’t require knowledge of internal code. Hence, it is often simpler to start and more cost-effective to carry out compared to white box testing and gray box testing. That’s why companies may prefer black-box testing over white-box testing.

Functional vs Non-functional Testing: Key Differences

What is functional testing and non functional testing?

Functional and non functional testing are both popular and essential software testing types that help verify if a software’s features work correctly and assess aspects like performance and security for overall reliability.

The differences between functional and non-functional testing lie in their respective focuses. Functional tests focus on verifying if the required functions are met, whereas non-functional tests evaluate non-function aspects of any software such as performance, stability, efficiency, usability, visuals, etc.

Functional testing and non functional testing: Key differences

Put simply, functional test tries to answer if the software’s important functions are operating, while non-functional tests care more about how the operations occur.

What are the differences between functional and non-functional testing?

Let’s explore the key differences between functional and non-functional testing in the table below:

Why is Functional Testing Important?

Software functional testing is an important phase of the software development life cycle (SDLC) for a variety of reasons:

Functional testing benefits

• Verification of requirements: Functional test guarantees that the software meets the requirements. By testing each function or feature, you can ensure that the application acts as expected and meets the functional criteria.
• Bug detection: One of the key goals of functional test is to find and disclose bugs or problems in software. It aids in identifying disparities between predicted and actual results, allowing developers to correct flaws before the software is published.
• Software quality improvement: Functional testing helps to improve the overall quality of software by verifying that every module or component carries out its assigned task correctly.
• User experience optimization: Functional tests improve user experience by identifying and correcting issues early in the SDLC. It helps develop a software product that satisfies users’ expectations and reduces post-release problems.
• Cost-effectiveness: Resolving problems at a later stage of the software development life cycle or after the product has been delivered is more expensive than identifying and repairing errors early in the process. Functional test lowers the overall cost of development and maintenance by assisting in the early detection of issues.
• Risk mitigation: Functional testing assists in reducing the risks related to software development by methodically testing the program’s functioning. It gives teams information about the application’s usability, performance, and dependability so they may proactively solve any possible problems.

Types of Functional Testing

What are the most common functionality testing types? Here are the most common functional testing examples:

Types of functional testing

Regression testing

Regression testing ensures that new code does not break current functionality. It determines whether or not the application’s quality has deteriorated. These tests focus on the changes made and guarantee that the entire application is stable.

Unit testing

Unit testing involves breaking down the desired result into smaller units, which allows functional testers to check if a limited number of inputs, sometimes even just one, delivers the desired outcomes. By focusing on testing a specific part of the code, such as a function or method, unit testing is quick to write and run.

Integration testing

Integration testing verifies whether each software parts work properly together. This testing makes sure that the modules function properly when they are dependent on one another, even if they pass independent tests.

Smoke testing

Smoke testing is frequently used when a new build is developed. As an early-stage testing type, this method provides an additional layer of verification to determine whether the new build can move one or requires revisions. 

Sanity testing

A sanity test is executed for a new build that includes small bug fixes or new code, frequently after smoke testing. This method is to verify if every major functionality of an application operates properly both on its own and in combination with others.

Usability testing

Usability testing evaluates a software product’s user interface and overall user experience and addresses usability issues. In this testing method, real users will test the product in a production environment. Their feedback will be collected for future improvements.

How to Perform Functional Tests

QA functional testing typically includes the following essential steps:

How to perform functional test?

Identify test input

Before the testing phase, quality engineers need to determine the function that needs to be tested, along with its requirements, and how it operates. This essential step allows functional testers to understand the function’s goal and learn the potential user paths.

Create test scenarios

Create a list of every potential test scenario—or at least every crucial one—that may be used for a particular feature. Test scenarios demonstrate how a feature will be used in different contexts. For example, test cases for a payment module might include different currencies, managing expired or invalid card numbers, etc.

Create test data

Based on the test scenarios that you selected, create test data that replicates typical use situations. Input the test data manually with tools like MS Excel, or automatically with a script or testing tool that retrieves data from sources such as a database, flat file, XML, or spreadsheet. Make sure that each input data has relevant information specifying the expected outcome it should produce.

Execute test cases

In this stage, the created test cases are run and the results are recorded. After that, compare the expected and real output. The actual output produced after running the test cases is compared to the predicted output to determine the level of variance in the results. This stage indicates whether or not the system is operating as intended.

Why Automate Functional Testing?

There are various advantages of functional testing automation during the SDLC. The following are some reasons why organizations decide to automate functional testing:

• Efficiency and speed: Automated functional test can be completed faster than manual tests. This leads to more rapid feedback on the software’s quality, which allows more frequent updates and faster release cycles.
• Reusability: Automated functional tests can be repeated without extra work and reusable at various phases of the development process. This allows consistent testing across different builds and releases, cutting down on redundancy.
• Improved test coverage:  Automated functional test offers wider coverage of test scenarios and data variances. This leads to higher test coverage, ensuring that all of the application’s components are carefully tested.

In summary, automated functional test improves the software development process’s effectiveness, consistency, and dependability, which leads to better products and quicker release cycles.

2. What is non-functional testing?

In contrast to functional testing, non-functional testing assesses factors including scalability, performance, usability, and dependability. Rather than focusing on particular features or functionalities, it evaluates the system’s non-functional characteristics, such as reaction time, load management, and security.

3. What is the difference between unit testing vs functional testing?

Unit testing is a type of functional testing in which the validity of individual modules or components is verified by testing them separately. More broadly, functional testing evaluates the system’s functionality as a whole.

4. What is the difference between functional vs regression testing?

Regression testing makes sure that new features don’t negatively affect already-existing functionalities, while functional test confirms that the program operates as intended. Although being one of the functional test types, regression testing focuses on potential problems with new changes, whereas functional test validates features.

5. What is the difference between functional vs integration testing?

While integration testing evaluates the connections between various systems or components, the functional test looks at specific functions on their own. Both are a component of functional testing; integration testing makes sure these features work together seamlessly, whereas functional testing concentrates on features.

Final Thoughts About Functional Testing

In conclusion, functional test is the key to ensuring software reliability and user satisfaction. Its comprehensive examination of each function not only addresses and fixes possible issues but also guarantees a seamless alignment with user expectations.
