What is Software Security Testing?

What is Software Security Testing?

Software security testing (SST) is the process of identifying and eliminating vulnerabilities in software. It’s a critical part of any software development project, but it can be difficult to get started with SST because there are so many different types of tests and security tasks that need to be performed.

Software security testing has become an essential part of the software development process and testing. A veteran security testing company such as ours offer on-demand software security testing services by security experts that are designed to identify flaws in the code before they can be exploited, providing peace of mind before release.

There are also many different tools available for performing these tests for security issues, which makes it even more confusing. This article will help you understand software security testing, types of software security testing, and the best way to ensure your software is secure.

Types of Software Security Testing

There are two main types of software security testing; manual testing and automated testing.

Manual Testing

Manual testing is a time consuming and painstaking process where an individual or team inspects software to discover weaknesses in the application and how it should be improved. There are many different types of manual tests, but they all have one goal: to find bugs. Though it can be time-consuming, manual testing can greatly improve the quality of a software product.

Automated Testing

Automated testing is the process of executing test cases automatically. Automated testing may be executed by running a software application under test through its path of execution in an automated fashion. The results of the execution might be checked and compared to expected results, or they might be disregarded if not within certain tolerances. Test automation has been widely used in software engineering for decades to improve efficiency, find bugs and reduce defects in systems. Automated tests are typically written using tools such as a test automation framework or an automated regression tester (ART). There have been many articles discussing the benefits of test automation, its impact on software development is one of the more popular topics.

What are Software Security Testing Services?

Software security testing services are services that provide software security testing for custom applications. Software security testing services intend to test the confidentiality, integrity, and availability of software to ensure that a certain level of protection is achieved for its users. They conduct tests at different stages such as requirements analysis, architecture design, development/test cycle, and production deployment. These tests can be conducted manually or automatically through tools such as software testing tools.

What are the advantages of Software Security Testing Services?

There are many advantages to software security testing services. Some of the advantages include:

  1. Identify potential security risks in software before it is released.
  2. Ensure that software meets all security standards.
  3. Improve the overall security of software.
  4. Reduce the chances of software vulnerabilities being exploited.
  5. Preventing data breaches
  6. Ensuring compliance with security standards and regulations
  7. Improving the overall security of the software

The main advantage of having a software security testing service by security experts is that your business will not be adversely affected by costly technology decisions, and you’ll have peace of mind knowing that your application is safe. You can also save time, money, and effort by outsourcing this work to an experienced team who has already done it before.

Why is Software Security Testing Required?

Software security testing is an important part of the software development cycle. It can be done in different phases of the Software Development Life Cycle (SDLC). The goal of software security testing is to find vulnerabilities in the software before it gets deployed to production. This will minimize the impact of any potential vulnerabilities and prevent attackers from exploiting them later. Security testing also helps find bugs that are not related to security issues like performance or usability issues.

Software security is a key factor in the development of software systems. It is important to ensure that both the design and implementation of software are secure. There are various approaches to achieving this goal.

Software Security Testing: Our Approach

 

Architecture Study & Analysis

Most development initiatives begin by specifying software requirements that describe what the business wants from the project. In a technology project, software requirements often include specific functional or non-functional specifications that detail how the feature will work in practice, as well as business or performance requirements that help with project management and define how the feature will be built at the highest level.

Threat Identification

The first step we perform in developing secure software is to identify the threats that your software might be exposed to. We employ many approaches to developing secure software, including application penetration testing services, vulnerability assessment, code review and threat modeling. One of the most common types of threats faced by organizations today is cyberattacks. This includes malware and ransomware attacks as well as denial-of-service attacks which aim to disrupt or disable a computer network or system. Our team of experts provide services to identify, manage and resolve any possible threats and vulnerabilities that might arise from the use of information and communication technology at the level of people, processes and systems.

Test Planning

Test planning should take the insights gained during requirements or product analysis and turn them into an established QA strategy. The resulting strategy documentation is intended to convey exactly what testing is about to be performed, or will not be performed, using clearly defined requirements and goals. The testing strategy should be updated as requirements and user insights change and should be centrally located in the product management system. A testing strategy typically focuses on defining acceptance criteria, which are the set of conditions that must be met in order for a product to satisfy its need. Testing strategies may also include techniques such as “black box” testing,

Testing Tool Identification

In the software testing approach, test tools are the products used to support test activities. The testing tools can be used to support manual or automated test activities in developing applications. The kinds of software testing tools used in software development will depend on the nature of the application to be developed. In a unit software testing approach, test tools are typically used to test individual source code modules. In an integration testing approach, test tools are typically used to test the interactions between software modules.

Test Case Development

Test development entails employing both human and automated testing to ensure that the software’s functionality is fully covered, with the process being guided by the requirements established beforehand. Because human testing cases are presented in the form of cheat sheets, test cases for automated testing are frequently produced separately.

Test Case Execution

The tests are carried out using pre-written test documentation and a properly setup test environment. The test management system keeps track of all test outcomes. Negatively passed tests, in which the actual result differs from the intended result, are marked as errors, and sent to the development team for revision, with rechecking after repair. The tests are executed in the test environment without a live user interface.

Reporting

The testing team submits a test closure report at this point, summarizing and communicating its results to the rest of the team. This report usually contains summaries of the testing effort and findings, as well as an appraisal of the testing and the approval of the manager. The test closure report may be submitted directly to the project sponsor or manager, or it may be routed through a QA lead, product manager, quality assurance director, and other stakeholders. The report may also include contact information for the team members so that these individuals can receive further questions and inquiries from the project sponsor.

What is a Software security Vulnerability and What Are Some Examples?

Software security vulnerability is a weakness in the code of a software. Many programs contain flaws in the code that allow hackers to take advantage of the computer.

Software security vulnerabilities can be classified into two main categories: software bugs and design flaws. A bug is a mistake in the code that causes it to behave incorrectly, while a flaw is an error in the way the program was designed or implemented.

Some examples of software security vulnerabilities are buffer overflows, cross-site scripting, and SQL injection.

  • Buffer overflows occur when a program tries to store more data in a buffer than it is allocated to hold. This can cause the program to crash or allow an attacker to execute code on the system.
  • Cross-site scripting (XSS) vulnerabilities occur when an attacker injects malicious code into a web page that is then executed by unsuspecting users who visit the page. This can allow the attacker to steal sensitive information or hijack the user’s session.
  • SQL injection occurs when malicious code is inserted into a SQL query, which can allow the attacker to steal sensitive information or use the database for malicious purposes.

Here is a list of the most common of software security vulnerabilities that software developers should be aware of:

  • Malware. Also known as malicious software, malware is a general term that refers to any type of software, including viruses, worms, trojans, adware and spyware. These programs are designed to do things like steal your personal information, damage your hard drive, or even harm you physically.
  • Phishing. A form of social engineering that involves the fraudulent use of email to obtain sensitive information such as usernames, passwords and credit card details. The perpetrator sends an email pretending to be from a legitimate source in order to trick users into revealing their credentials.
  • Pharming. A technique used by attackers to redirect a victim’s browser request to a website controlled by the attacker. In some cases, phishing attacks are combined with pharming to bypass firewalls.
  • Proxies
  • Spyware. A type of malware that can be installed on your computer without you knowing. It gets into your system and monitors all the information you do online, such as your search history, browsing habits, emails, chats, etc
  • Adware. A type of malware that displays advertisements on the computer screen. It can be used to make money for its creators, or it may simply be a way for them to promote their own websites and products. The ads are usually
  • Botnets. A botnet is a network of computers that has been infected with malicious software. The malware then uses the infected machines to send spam, launch denial-of-service attacks or steal sensitive data from other computers on the Internet.
  • Spam. Unsolicited bulk e-mail (UBE) is an electronic communication sent to many recipients. It can be used for commercial purposes such as advertising and marketing, but it may also be used by spammers to distribute viruses, worms, spyware, adware, and other types of malware. Spamming is illegal in many countries.
  • Missing data encryption
  • OS command injection. A vulnerability that allows an attacker to execute arbitrary commands on a target system. This can be used for privilege escalation, or simply to gain access to the compromised host.
  • Injection Flaws/ SQL injection. These occur when untrusted data is fed into an application, resulting in the execution of unintended actions or commands. SQL injection is a well-known type of injection flaw.
  • Buffer overflow. A common vulnerability in software. They occur when the size of an array or buffer used to store data exceeds its capacity. The attacker can then use this flaw to overwrite memory that will be used by other parts of your
  • Missing authentication for critical function
  • Missing authorization
  • Unrestricted upload of dangerous file types
  • Reliance on untrusted inputs in a security decision
  • Cross-site scripting (XSS). These allow attackers to inject malicious code into webpages viewed by other users.
  • Template injection. This is an example of an attack where the attacker tries to insert a malicious HTML or PHP script in a vulnerable page.
  • A download of codes without integrity checks
  • Use of broken algorithms
  • URL redirection to untrusted sites
  • Path traversal. In computer science, path traversal is the process of walking along a graph or tree structure to reach some goal. The term “path” can be used to refer to either an ordered sequence of nodes (a walk) or a set of paths through the same node(s).
  • Software Bugs. A bug is a mistake in the code. It’s not necessarily an error, but it can be and often is. A bug is usually caused by a programmer making a mistake while writing or testing the program. The programmer might
  • Weak passwords

Types of Software Security Testing

There are many types of software security testing used to identify software vulnerabilities and weaknesses. One of the most common types of software security testing is Black Box testing, which involves examining the input and output without looking at the code. White Box testing, on the other hand, involves examining both the input and output as well as the code. A third method called Grey Box testing examines only the code and input. In situations where any kind of testing is required but no one knows how white-box testing can be employed to check for bugs.

Static application security testing (SAST)

Static application security testing (SAST), or static analysis, is a testing methodology that assesses the security of a source code application to find potential vulnerabilities before the code is compiled and executed.

The three forms of security testing are done in a completely different manner. Black box means the type of testing involves the evaluation of the source code from outside the application. SAST is a form of black box testing that analyzes source code for the presence of security vulnerabilities. Whereas static analysis is performed from inside the application. Static analysis is much more thorough than black box testing because it allows you to analyze the source code line by line.

The most popular SAST tools are:

  • BinScope Binary Analyzer
  • Coverity Scan
  • Fortify SCA
  • Klocwork Static Code Analyzer
  • Parasoft C/C++test

Compliance Testing

Compliance testing is a process that verifies the compliance of an organization with the applicable laws and regulations. It’s also known as internal audit, risk management or quality assurance. The purpose of this testing is to ensure that your business complies with all relevant legal requirements.

  • Standards-based security testing, OWASP Top 10, and SANS Top 25
  • GDPR Compliance
  • HIPAA Penetration Testing
  • PCI Penetration Testing
  • NERC CIP Compliance

Application Penetration Testing

Application Penetration Testing (also known as pen testing) is a security exercise in which a cyber-security professional tries to uncover and exploit flaws in a computer system. The goal of this simulated attack is to find any vulnerabilities in a system’s defenses that attackers could exploit. to gain access to the system. The term “penetration testing” is often used interchangeably with the term “ethical hacking”. However, unlike ethical hacking, application penetration testing services are not limited to a particular scope of knowledge or skill set. It can be performed by even highly technical and novice individuals.

Red Teaming

Red teaming is the technique of using an adversarial approach to thoroughly challenge plans, policies, systems, and assumptions. A red team can be a hired outside firm or an inside group that employs tactics to stimulate outsider thinking and provide a check on insiders’ thinking. The red teaming process is based on the premise that plans are often flawed. It’s also based on the understanding that every plan, policy, or strategy will be related to a set of assumptions. Those assumptions need to be brought into question and confirmed or replaced with new ones. The process typically involves having an outside group (typically hired by a corporation or the government) develop, test, and refine a plan within the group. The red teaming process allows for realistic testing of a plan or strategy with different assumptions and provides an opportunity for multiple perspectives to contribute valuable insights.

Load Testing

Load Testing is a form of software testing that focuses on the performance of an application when accessed by multiple users at the same time. It is performed to improve performance bottlenecks and to ensure that the application is stable and runs smoothly before it is deployed.  The backbone of this testing is a stress test system. The stress test system typically consists of one or more client machines and a server machine. The server machine is the focus of the exercise, and it runs real-time applications on multiple virtual machines hosted by the provider. It can also be known as load testing, performance testing, stress testing, and responsiveness testing.

Tracing the Origin of Defects

Tracing the origin of defects or debugging is a tedious process, therefore it is very important to be able to identify the source of the software defects. It is even more important to be able to identify the source of the software defects before new features or modifications are introduced. into the system. Software defects include, but are not limited to, the following items:

  • Division by zero
  • Out of bounds memory access
  • Invalid pointer dereference
  • Stack overflow
  • Numeric overflow

SQL Injection Testing

SQL injection testing is a method of testing an application to see if it is possible to inject data into the application so that it executes a user-controlled SQL query in the database. Developers use SQL injection testing to check if they are vulnerable to SQL injection attacks. The code fragments shown are all valid queries that can be injected.

Thick client testing

Thick client pen-testing involves both local and server-side processing and often uses proprietary protocols for communication. Thicker client testing may involve both client-side and server-side evaluation and may use proprietary protocols for communication. Thick client pen-testing often delays the attack for hours or even days. This makes it particularly effective against a constantly changing target, as well as in situations where an attacker is attempting to remain undetected.

IoT and embedded software testing

Embedded testing is the process of discovering defects in a newly developed software or hardware. It ensures that a newly created software or hardware is defect-free. Embedded software testing is primarily conducted by the developers themselves but may also be carried out by external testers. Testing embedded software can be broken down into three processes: Unit Testing, Integration Testing, System Testing

Unit testing, also known as component or module testing, is done on specific pieces of application source code and is often used to test the individual parts of an application. This method of testing ensures that the necessary components are working together to create a whole system that works as it should.

Mobile Application Security Testing

Apps that allow users to send text messages or download files from unknown apps without the app store reviewer vetting them may not be secure. Mobile Application Security Testing ensures that apps do not store personal information or files from another app without the user’s knowledge and permission. In many cases, apps store personal information or files from another app on their servers to make it easy for the users to download files when they need them. The app developer must take care not to expose the user’s personal information or files when sending text messages or downloading files from an unknown app.

Network Security Penetration Testing

Network security penetration testing is a process of evaluating the security of an information system by testing the system against a set of predetermined threats. Wireless, ethernet, hardware/IoT (internet of things), phishing emails, and physical access are common ways hackers gain access to networks and data. Testing in these mediums can lead to security risks and breaches. A network security tester is typically responsible for identifying vulnerabilities in computer networks and systems, as well as assessing the risks and potential consequences related to these vulnerabilities.

Static Application  Security Testing

Analyzing the application source code itself is called static application security testing (SAST). SAST is a form of black box testing, is the process of analyzing source code for the presence of security vulnerabilities. The two forms of security testing are done in a completely different manner. Black box means the type of testing involves the evaluation of the source code from outside the application. Whereas static analysis is performed from inside the application. Static analysis is much more thorough than Black Box testing because it allows you to analyze the source code line by line.

Dynamic Application Security Testing

Dynamic Application Security Testing or DAST is a security assessment tool that can detect certain web application weaknesses if an expert attempts to enter the production web applications. Dynamic Application Security Testing uses an experienced DAST tester also called a black box tester to use the same techniques that an attacker would use to find weaknesses.

Security Risk Assessment

security risk assessment is a process by which an organization identifies and evaluates the risks of an application (e.g., a mobile application, a business application, etc.). It is primarily used to identify key security controls as well as application defects and vulnerabilities. A vulnerability is a condition that might allow an attacker to compromise the security of a system, application, or network. Vulnerabilities can be classified as either technical vulnerabilities (e.g., design flaws in software) or nontechnical vulnerabilities (e.g., human error). An exploit is any attack technique designed specifically to take advantage of a security vulnerability. Exploits happen when an attacker uses a vulnerability in an application, operating system, or network to take control of the affected systems and then potentially to use them maliciously. An exploit launched by a software vulnerability typically targets a specific target computer with the intention of taking advantage of that computer’s resources and/or confidential data. An exploit launched by a hardware or software vulnerability typically targets the computer system’s resources and/or confidential data.

Cloud Security Penetration Testing

Cloud or server-based attacks threaten the confidentiality and integrity of data on the Internet. To detect all those threats, cloud or server-based attackers need to know how to test the systems. Cloud Security Penetration Testing has four basic steps: Determine your target, discover if the cloud is trustworthy, exploit vulnerabilities, fix vulnerabilities and close security holes To do this, it is important to determine their target. This will help you decide what kind of cloud security penetration tests to perform.

Web Application Security Testing

Web Application Security Testing is type of software security testing often used by hackers and cyber-security experts, to gauge the security strength and security posture of a Web application to determine if it is secure. This testing is often done using manual and automated security testing techniques.

API Security Penetration Testing

API security penetration testing is a process that involves scanning your API (Application Programming Interface) to ensure that it is secure. This has traditionally been done manually by your enterprise security team. In recent years, API security testing has become a popular process, in which hackers utilize various techniques to uncover flaws in the APIs.

Amazon Web Services (AWS) Penetration Testing

With Amazon Web Services (AWS) Penetration Testing the security engineers focus on reviewing the configuration of the cloud and applications being utilized by the company. AWS Penetration Testing services is different from normal pen-testing which is a process usually employed by companies to find potential security flaws in the infrastructure and applications behind a Web site’s operations.

What We Learned from MES Fall 2019

What We Learned from MES Fall 2019

Needless to say, it was a quite a busy start of autumn here at Euro Testing Software Solutions. And it all started with the MESS conference in Phoenix, Arizona. However, now that we are back in the office, we went over our notes and decided to share what we found especially interesting at the conference.

  • Basic needs are important: Although it’s considerably larger than Europe as a market, the US medium enterprise market seemed smaller in terms of variety of project requests, mainly consisting of lots of clients that try to find solutions to somewhat basic software testing needs. However, while the complexity of demands is not that vast, the expected scale of implementation is.
  • Cybersecurity focus: We’ve noticed that most project requests for application development revolved around cybersecurity. It remains a hot topic in the US market. Following that, the most sought expertise was software testing automation and related services (DevSecOps, RPA). Lastly, there was a lot of discussion around cloud architecture and IoT.
  • Every cent counts: Most IT infrastructure/ Development budgets seemed to be allocated towards clearly defined, fixed-price projects and less on broader service offerings (off-shoring, managed services etc.). All-in-one services were a tough sell.
  • Trust trumps hype: Regardless of project size, having great references is key for the US market. This becomes especially relevant when new(er) products & services are introduced. We were pleasantly surprised that people remembered us from last year’s conference, and this worked as an argument for new engagements.
  • Software Testing as a Pizza: Lastly, the “reinterpretation” of our services was a hit. Repackaging functional testing, regression testing, performance & security testing as types of pizza (plus positioning RPA & Automation as toppings) helped participants get a better understanding of their relevance in specific stages of an application’s lifecycle.

Fun fact: We found it very interesting that there were a lot of discussions around Arizona’s 5 key industries: cotton, cattle, citrus, copper & climate. We hope our experience can prove helpful. If you would like to know more about our mix & match software testing services, contact us for more information.

5 Things Cyber Criminals Don’t Want You To Know About How They Can Enter Your Business – Part 1 (With Recommendations)

5 Things Cyber Criminals Don’t Want You To Know About How They Can Enter Your Business – Part 1 (With Recommendations)

Risk Based Testing is all about evaluating and pointing the likelihood of software failure. What’s the probability that the software will crash upon release? What would the expected impact look like?  Think about “know-unknowns” in your software – this is what risk based testing is trying to unearth.

While it would be wonderful if we could have unlimited resources for testing – from our experience this is wishful thinking. Choices have to be made, and most of the time we go after issues that could prove critical for the business. When we define risk, we look at two dimensions as defined by HPE ALM (https://saas.hpe.com/en-us/software/alm): Business Criticality and Failure Probability. The first measures how crucial a requirement is for the business and the second indicates how likely a test based on the requirement is to fail.

Assessing risks 

While there are many ways to approach risk assessment, we usually use HPE ALM because it’s a reliable tool and saves us a lot of time. It has an integrated questionnaire that allows us to determine the risk and functional complexity of a requirement and give possible values for each criterion plus a weight assigned to each value. This allows us to evaluate the testing effort and determine the best testing strategy.

In assessing risk, comparing the changes between two releases or versions is fundamental for quality assurance to identify the risk areas, reducing the total testing efforts, managing project risks, bringing lots of value with less effort and more efficient testing.

The testing team can explore the risks and provide their feedback on the test execution and whether or not to continue testing.

Advantages vs Disadvantages

For some projects, the big challenge is to accommodate the need to reduce development time, while maintaining the scope. Under these conditions, a smart risk testing approach is key in allowing the testing team to develop their software in a timely manner, making the testing effort more efficient and effective.

Dealing with the most critical areas of the system first will counteract the additional time and costs of solving those issues at a later stage in the project. And maximize on the fact that the time is spent according to the risk rating and original mitigation plans.

A faster time to market and reduction of cost per quality are more easily achievable with this risk-oriented approach.

Proper risk identification in the analysis process, prevents the negative impact that assessing a risk as too low or based on too subjective criteria, could have.

Identifying potential issues that could affect the project’s cost or outcome, create an efficient risk-based testing work and ensure better product quality.

Overall Benefits

Using a testing approach that takes risk into account, promotes some of the best practices in risk management, while conducting fewer tests with a more focused view on critical areas, higher testing efficiency, and increased cost-effectiveness.

We invite you to test these benefits out for yourself and try on this software testing approach for size. If the size fits don’t hesitate to share some of your best practices in risk assessment software with us at Euro-Testing.

Or if you are not sure what testing approach would suit you best, let us know here! And we will tailor the best solution for your needs.

Who Tests the Tests?

Who Tests the Tests?

Let’s begin with an analogy about software testing. Suppose for a moment that bugs are like medical conditions (no pun intended). The process we use to identify them is like the medical one: through differential diagnosis. We detect the harmful situation and offer a course of treatment. Yet we are all familiar with situations where things can get complicated, just like in the medical field.  In software testing, one of the most challenging situations we can encounter relates to a particular type of errors: the false positives and false negatives. What are they and how do we approach them?

The false positive – our tests are marked as failed even if they actually passed and the software functions as it should.  We report errors even though they don’t exist. Data tells us the software should not work as intended yet it does.

From our experience, this type of error has an insidious impact. While it doesn’t affect the software itself, they tend to upset the dev’s trust in the software testing process.

Some can even begin to question the software testing company’s expertise. However, it’s usually uninspired to penalize testers for false positives (or even base KPIs on this) because it can only lead to an undesired situation – testers being scared to report them because of possible backlash. Also, keep in mind that most false positives are related to unclear situations – e.g. missing documentation. As cliché as it might sound – it’s better to be safe than sorry.

The false negative – our test are marked as passed even though they failed. We detected no problems at the moment of the test, yet they were present. The software will continue to run with glitches embedded even though it shouldn’t have.

What can happen? In a best case scenario, we detect them at a later stage of tests and fix them. Bad case: we notice them after the software has been deployed.  Worse case: the bugs remain in the software for an indeterminate amount of time.

The main problem with these errors is that they can affect the business bottom line by “breaking” the software.

We think that one of the best ways of detecting false negatives is to insert errors into the software and verify if the test case discovers them (linked with mutation testing).

What can we do about it?

Some argue that reporting false positives is somewhat preferable to missing false negatives. This is because while the first keep things “internal” the second have wider business implications: from bad software to unhappy end-users.

We should keep in mind is that they are by nature hard to detect. Their causes can vary:  from the way we approached the test to the automation scripts we used and even to test data integrity.

From our experience, having test case traceability in place works best to prevent both them. When was the first time the failure showed itself? Can we track it back in time? Was it linked with extra implementations? Did some software functionalities change? Does the test data look suspicious? These questions usually help us figure out which test cases were most likely affected.

All things considered, we believe it all comes down being responsible in software testing. It’s important to actually care about the test and not just do a superficial track & report

If you think you might be dealing with false positives and negatives errors in your software tests and need some guidance, drop us a line.

We invite you to test these benefits out for yourself and try on this software testing approach for size. If the size fits don’t hesitate to share some of your best practices in risk assessment software with us at Euro-Testing.

Or if you are not sure what testing approach would suit you best, let us know here! And we will tailor the best solution for your needs.
