Security Testing: Ensuring Software is Secure And Free From Vulnerabilities

Published On: May 10, 2023

With the rising number of security breaches recently, it is crucial to incorporate safety measures into your program. Only by adopting robust software security testing procedures can companies ensure the safety of their apps and other digital products that deal with sensitive information from consumers, clients, and partners.

Not only do businesses utilize and sell online payroll systems, shopping carts, banks, and stock trading programs, but consumers can also buy them.  This implies that users and consumers have come to rely on the safety and security of online applications. Such a security feature is, without a doubt, crucial for desktop apps as well. Ensuring software safety is important in every business scenario and hence learning Software Testing Training in Chennai fetches you worthy opportunities in top MNc.

The need for security measures, however, skyrockets when discussing the internet. No one will ever use a website for business if their financial information is not secure. There is no need to define “security” or treat it as a nuanced notion. The integration of security testing into the software development lifecycle is now standard practice.

Finding and fixing software security flaws is what software security testing (SST) is all about. Although SST is essential to every software development project, getting started can be challenging due to the wide variety of tests and security-related activities that must be completed.

It’s even more difficult given the number of tools available for doing these tests for security flaws. Learn about the many types of software security testing and the most effective strategies for making sure your software is safe to use by joining the Software Testing Training in Chennai at SLA, the premier IT training institute.

Software Security Testing – What is It?

Software security testing is a process that guarantees the software does not have any potential vulnerabilities or flaws, dangers, or threats. This is done so that the software does not have the ability to harm the user system or the data contained within it.

It is now standard practice to publish software only after it has been subjected to comprehensive security testing, which may be repeated several times.

Nobody wants their data or information to be compromised due to software security breaches, whether they are an individual user, a company, or an organization. Maintaining confidentiality and integrity of your web app’s data is just as important as making sure it meets quality criteria for performance and usability.

Detecting and fixing application security flaws requires thorough software testing in today’s world. Enrich your knowledge of software testing concepts and test cases by registering with Software Testing Training in Chennai.

Services that perform software security testing on client-specific applications are known as software security testing providers. In order to guarantee that a particular level of protection is provided for its users, software security testing services aim to assess the privacy, integrity, and reliability of software.

Testing occurs throughout the development process, from initial planning through the final phases of manufacturing. These checks can be executed either manually or automatically with the help of software testing tools.

Primary Types of Software Security Testing

Manual testing and automated testing are the two primary types of software security testing.

Manual Testing

Manual testing is a laborious procedure in which a single tester or a small group of testers examine a program to look for bugs and make suggestions for enhancements. Manual testing takes numerous forms, but it always serves the same purpose: discovering flaws. Manual testing might be time-consuming, but the benefits to a software’s quality are well worth the effort.

Automated Testing

In automated testing, test cases are run without human intervention. To do automated testing, a software application can be automatically put through its paces. Execution outcomes may be validated against hypothesized outcomes or ignored if they fall outside of predetermined margins of error. Software engineers have relied on automated testing for decades to boost productivity, root out issues, and lower defect rates in their systems. Test automation frameworks and automated regression testers are common instruments for creating automated tests (ART).

The influence of test automation on software development is a common theme in the many publications written about its advantages.SLA offers extensive and exploratory Software Testing Training in Chennai in both manual testing and automated testing.

How to Do Software Security Testing?

The following methods can be used by the developer during preparation and planning for security tests:

Research and Evaluation of Architecture

The majority of development projects start with the specification of software requirements that outline what the organization expects from the development effort. In the context of a technology project, the software requirements typically comprise explicit functional or non-functional specifications that specify how the feature will operate in practice. Moreover, the software requirements may include business or performance requirements that assist with project management and outline how the feature will be implemented at the highest level.

Identification of Potential Threats

The first thing that we do while building secure software is to identify the potential threats to which your software could be exposed. When it comes to designing secure software, we make use of a wide variety of strategies, some of which include application penetration testing services, code review, vulnerability assessment, and threat modeling. Cyberattacks are one of the most common sorts of security risks that businesses and other organizations face in the modern day. This includes assaults using malware and ransomware, as well as attacks using the denial-of-service technique, which is intended to interfere with or cripple a computer network or system.

Software Testers offer services to identify, manage, and eliminate any potential threats and security flaws that may be brought about by the use of information and communication technology at the levels of people, processes, and systems. These services are provided to ensure the safety of the software. Become a successful software tester by signing up for Software Testing Training in Chennai.

Test Planning

The insights obtained during requirements or product analysis should be incorporated into an established quality assurance strategy before the test preparation phase begins. The documentation of the strategy that was produced as a result is supposed to express exactly what testing is about to be performed, or will not be performed, based on objectives and goals that are described very specifically.

A common repository for the testing plan ought to be established within the product management system, and it ought to be brought up to date if there is a shift in either the requirements or the user insights. Acceptance criteria are the conditions that must be satisfied before a product can be considered successful in meeting its target market’s requirements. Defining acceptance criteria is often the primary emphasis of a testing approach. Techniques like “black box” testing are also sometimes used in testing strategies.

Identifying the Testing Tool

Test tools are the goods that are utilized to provide support for testing activities in the software testing methodology. In the process of designing applications, the testing tools may be utilized to facilitate either manually performed or automatically performed testing operations. The type of application that will be produced will determine the software testing tools that will be utilized during the development process of the software.

Unit software testing is a way of testing software in which individual source code modules are put through their paces using various testing tools. Test tools are often put to use in an integration testing strategy in order to test the interactions that occur between different software modules. Learn about various software testing tools and gain comprehensive knowledge about software testing by joining Software Testing Training in Chennai at SLA.

Test Case Development

Test development requires the use of both human and automated testing in order to guarantee that all of the functionality of the program is thoroughly covered, with the process being directed by the requirements that were developed in advance. Test cases for automated testing are generally prepared independently from those for human testing because human testing cases are typically supplied in the form of cheat sheets. Learn about the creation of test cases by acquiring knowledge from the Software Testing Training in Chennai.

Test Case Execution

The tests are executed with the aid of pre-written test documentation and a test environment that has been set up appropriately. The test management system is responsible for maintaining a record of the results of each test. Negatively passed tests are those in which the real result is different from the result that was intended.

These tests are flagged as mistakes, and the development team is tasked with revising them before they are rechecked after being fixed. In the test environment, the tests are carried out, but there is no actual user interface present. Become a certified software tester by enrolling in the software testing certification training in Chennai.


At this stage, the testing team is responsible for submitting a test closure report, in which they communicate and summarize their findings to the other members of the team. This report will often include summaries of the testing effort and findings, as well as an evaluation of the testing and the manager’s approval. It is possible to deliver the test closure report straight to the project sponsor or manager, although it is also possible to route it through a quality assurance head,  quality assurance director, product manager, and various other stakeholders.

It’s possible that the report may also provide contact information for the members of the team, which would allow the project’s sponsor to ask those persons additional questions and provide additional clarification. No matter even if you don’t have a programming background, you can easily switch your career to IT by becoming a successful software tester by joining Software Testing Training in Chennai.

Software Security Vulnerability

In computer programs, a security vulnerability is a potential entry point for malicious code. Numerous programs have vulnerabilities in their coding that can be exploited by hackers.

There are two primary types of security issues in software: bugs and design defects. 

The difference between a bug and a flaw is that a bug is an error in the code that results in the program behaving erroneously, whereas a flaw is an error in the manner in which the program was planned or implemented.

Vulnerabilities in Software and Some Examples

Buffer overflows, cross-site scripting, and SQL injection are all instances of security flaws in software.

To put it simply, a buffer overflow happens when software attempts to store more information in a buffer than the buffer can actually retain. The program may crash or an attacker may gain control of the system.

Vulnerabilities known as cross-site scripting (XSS) occur when an attacker inserts malicious code into a web page, which is then deployed by users who visit the website without their knowledge. The attacker may then be able to access private data or take over the user’s session.

A SQL injection happens when an attacker inserts malicious code into a SQL query, giving them access to the database and the potential to steal data or do other forms of database abuse. Learning about the most possible security threats and vulnerabilities in a software product is essential to stay aware of any harmful attack. Hence, acquire thorough knowledge about software testing through our Software Testing Training in Chennai at SLA.

The most prevalent types of software security flaws that programmers should be aware of are as follows:

  • Malware. Malware, short for harmful software, encompasses not just viruses and worms but also trojans, adware, and spyware. These apps are malicious and can steal information from your computer, corrupt your data, or even cause bodily harm.
  • Phishing. Email phishing is a sort of social engineering in which personal information like passwords and credit card numbers is stolen via phony emails. To steal users’ credentials, the bad actor poses as a trusted organization and sends them an email.
  • Pharming. Redirection is a tactic used by cybercriminals to trick victims into visiting malicious websites. Pharming is sometimes used in conjunction with phishing attempts to get around security measures.
  • Proxies
  • Spyware. Malware can be secretly installed on a device without the user’s knowledge. It infiltrates your computer and keeps track of everything you do online, from search terms to websites visited to emails read to chats participated in.
  • Adware. Adware is a sort of malicious software that causes unwanted pop-up ads to appear on the screen. Its authors may use it to advertise their own services and websites, or they may use it to monetize their efforts. Usually, the commercials
  • Botnets. When multiple computers are compromised by malware, they form a botnet. Infected computers may subsequently be used to spread spam, conduct DDoS attacks, or steal personal information from other users.
  • Spam. Unsolicited bulk email (UBE) refers to electronic messages delivered to multiple recipients without their consent. It has legitimate business uses like advertising and marketing, but spammers may also exploit it to spread malware including viruses, worms, spyware, adware, and more. In a number of nations, spamming is against the law.
  • Failure to encrypt data
  • Injecting OS Commands. A security hole that could let an attacker run malicious code on the compromised machine. This can be exploited to acquire root access to the compromised host or to elevate one’s privileges on that host.
  • SQL injection vulnerabilities. They occur when an application receives unreliable information, which causes it to carry out inappropriate tasks. One common form of injection vulnerability is SQL injection.
  • Overflowing buffer. One of the most typical types of software flaws. They manifest themselves when the quantity of data to be stored in an array or buffer exceeds the available space. Because of this vulnerability, an attacker can overwrite data that you intend to utilize in other places.
  • An essential function is lacking authentication.
  • Lack of permission
  • Permissionless sharing of potentially harmful files
  • Making a safety judgment without reliable information.
  • Internet-wide scripting (XSS). These vulnerabilities allow attackers to compromise websites visited by unsuspecting victims.
  • Injection of a template. Such an attack often involves the injection of malicious HTML or PHP code onto a susceptible page.
  • The downloading of programs without verifying their integrity
  • Using flawed algorithmic methods
  • Potentially malicious URL re-routing
  • Following a route. To accomplish a task in computer science, one must “traverse” a graph or tree structure. A path can be either a sequence of nodes in a predetermined order (a walk) or a collection of paths that all share the same node (s).
  • Flaws in the program. A bug is a flaw or error in the software. It’s not always wrong, but it happens a lot. When a programmer makes a mistake when writing or testing code, it usually results in a bug. A programmer may use insecure passwords.

Different Types of Security Testing in Software Testing

Several forms of software security testing are available for finding security flaws in code. Black Box testing is widely used in software security testing since it examines the input as well as the output without looking at the code. In contrast, white box testing looks at the code, the input, and the output. Grey Box testing is a third approach that focuses solely on the code and input. White-box testing is used to find bugs when no one is familiar with the inner workings of the system being tested.

Static Application Security Testing (SAST)

The purpose of static application security testing (SAST), also known as static analysis, is to identify security flaws in an application’s source code before it is compiled and used.

There is a huge difference between the three types of security testing. Black box testing is a form of software testing in which the code is analyzed in isolation from the rest of the program. SAST is a type of black box testing that looks for security flaws in the source code. Alternatively, static analysis happens within the program itself. Static analysis is superior to black-box testing due to its line-by-line analysis of the source code. The most often used SAST software includes:

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

Compliance Testing

In order to ensure that an organization is following all relevant legislation, compliance testing is performed. Internal auditing, risk management, and quality assurance are all terms for the same thing. The goal of this inspection is to make sure your company is following the law. Using the OWASP Top 10 and SANS Top 25 as examples of standards-based security testing

  • GDPR Compliance
  • PCI Penetration Testing
  • NERC CIP Compliance
  • HIPAA Penetration Testing

Application Penetration Testing

Often known as pen testing, is a type of penetration testing in which a professional in the field of cyber security attempts to find and exploit vulnerabilities in a software application. The purpose of this simulated attack is to identify security flaws in the target system. in order to log in and use the system.

The terms “penetration testing” and “ethical hacking” are often used interchangeably but have distinct meanings. Application penetration testing services, on the other hand, do not require the same level of expertise as ethical hacking. Even those with little to no technical experience can do it. Enrich your knowledge about software testing by gaining insights from the best software Testing Training in Chennai at SLA.

Red Teaming

Red teaming is a process whereby a group of people takes on an antagonistic stance in order to critically examine and question presumptions, rules, and procedures. A red team, sometimes known as a “swat team,” can be an externally contracted company or an internally formed group that uses techniques to encourage creative problem-solving from a different perspective and functions as a check on the dominant way of thinking.

The idea behind red teaming is that most plans have some sort of defect. Assumptions are important to this framework, as they are to any plan, policy, or strategy. These presumptions must be challenged and either verified or discarded in favor of more grounded ones. In this method, a company or government hires an outside group to come up with a strategy, then has that strategy tested internally.

Red teaming is a method of conducting thorough, realistic tests of a plan or strategy under varying assumptions, allowing for the combined insights of several experts. Know more about Res teaming by joining Software Testing Course in Chennai.

Load Testing

When several users access an application simultaneously, its performance is the primary focus of Load Testing. Pre-deployment testing is done to fix any bugs or performance issues and make sure the program is ready for prime time. The testing is built around a stress test system. One or perhaps more client machines and a server machine make up the stress testing system.

The exercise centers on the server machine, which hosts many virtual machines and processes real-time applications. Load testing is sometimes known as performance testing, stress testing, or testing for responsiveness. Become an expert in various types of software testing as SLA offers industry-aligned Software Testing Training in Chennai.

Finding the Origin of Defects

Identifying the cause of software bugs is crucial because of the time and effort required to track down their origin. Finding the cause of software flaws before adding new functionality or making changes is even more crucial. to the system as a whole. Problems with software can take many forms, such as those listed below.

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

SQL Injections Testing

The purpose of SQL injection testing is to determine if an application may be exploited by a malicious user to perform a custom SQL query on a database. To determine their level of protection against SQL injection attacks, developers perform penetration testing. All of the displayed code snippets are legitimate injection targets.

Extensive Client Testing

Thick client pen-testing typically makes use of custom protocols for communication and processing on both the client and server sides. Tests on a thick client may employ custom protocols for communication between the client and the server. Attacks can be postponed by hours or even days thanks to thick client pen testing. This makes it useful when facing a target that is always adapting, as well as when the attacker is trying to stay under the radar.

IoT and Embedded Software Testing

Defects in newly produced software or hardware can be found through a technique called embedded testing. It guarantees the flawlessness of newly developed software or hardware. Testing of embedded software is typically done by the developers themselves but can also be done by independent testers. Unit testing, integration testing, and system testing are the three main types of embedded software testing.

The term “unit testing” refers to testing that is performed on discrete units of source code, or modules, of an application. This technique of testing verifies that all of the system’s parts are interacting as they should. Gain knowledge of every detail of software security testing by means of dedicated instruction of experts at SLA, the best Software Training Institute in Chennai.

Mobile Application Security Testing

Unreviewed apps in the app store that let users send text messages or download files from unknown apps may not be safe to use. Checking the security of mobile applications guarantees that they won’t secretly save user data or data from other apps. It’s common practice for apps to save user data or third-party files on their servers, making them readily available in the event that users require them. When communicating with unknown apps or downloading files from them, app developers should take precautions to protect their users’ privacy.

Network Security Penetration Testing

Penetration testing in the realm of network security is a method of gauging the robustness of a computer network by subjecting it to a series of simulated attacks. Hackers often obtain access to networks and data using wireless, hardware/IoT (internet of things), ethernet, phishing emails, and even physical access. Security concerns and breaches may result from testing on these platforms. A network security tester’s duties often include the detection of security holes in a system or network and the evaluation of the associated dangers. Get your job-ready in the field of software testing by enrolling in the best Software Testing Training in Chennai.

Static Application Security Testing

Static application security testing refers to a code-level analysis of an application (SAST). Black box testing, of which SAST is a subtype, entails inspecting programs’ source code for bugs. Both types of security testing are executed in distinct ways. Black box testing is a form of software testing in which the code is analyzed in isolation from the rest of the program. Alternatively, static analysis happens within the program itself. Static analysis is superior to Black Box testing due to its line-by-line analysis of the source code.

Dynamic Application Security Testing

DAST, or Dynamic Application Security Testing, is a security evaluation tool that can identify vulnerabilities in web applications in response to an expert’s attempted entry into a live environment. An accomplished DAST tester, also known as a black box tester, mimics an attacker’s actions to identify vulnerabilities in an application.

Security Risk Assessment

When a company wants to know what dangers an app poses, they do what’s called a “security risk assessment” (e.g., a mobile application, a business application, etc.). Its primary function is to detect flaws and vulnerabilities in software applications and essential security controls. A security flaw is a potential opening in a system, program, or network that could be exploited by an adversary. Both technical (such as software design errors) and non-technical (such as social) factors can contribute to a system becoming vulnerable (e.g., human error).

An exploit is any form of attack that takes advantage of a known security hole. An exploit is a process by which an attacker takes advantage of a weakness in a computer system, program, or network in order to gain unauthorized access and, in certain cases, commit acts of malice using the compromised resource. When a software flaw is used to begin an attack, the compromised computer is normally selected at random, and its resources and/or data are then exploited.

The resources and/or private information of a computer system are often the objectives of an exploit launched via a hardware or software flaw. Know about the potential security threats to ensure software security by signing up for Software Testing Training in Chennai.

Cloud Security Penetration Testing

Internet data security is vulnerable to assaults that originate in the cloud or on servers. An understanding of how to test the systems in the cloud or on a server is essential for detecting all of these dangers. To do this, they must first define their target, then learn if the cloud can be trusted, then exploit weaknesses, repair vulnerabilities, and finally shut security holes. This will guide your selection of specific penetration testing for cloud security.

Web Application Security Testing

Hackers and cyber-security specialists utilize Web Application Security Testing, a subset of software security testing, to evaluate the safety of an Online application. Manual and automated security testing methods are commonly used for this purpose.

Penetration Testing for API Security

Application Program Interface (API) security penetration testing is a scan of your API to check for vulnerabilities. Your company’s security team has likely been manually performing this task up to this point. Hackers employ a wide variety of methods to probe APIs for security holes, and this practice has grown in popularity in recent years.

Penetration Testing on Amazon Web Services (AWS)

When doing an Amazon Web Services (AWS) Penetration Test, a company’s cloud and apps’ configurations are reviewed by the company’s security engineers. Normal pen-testing is a method used by businesses to look for security holes in the framework and code that runs a website; Amazon Penetration Testing services are distinct in this regard. Learn the best practices of Software Testing by enrolling in the best Software Testing Training in Chennai.

Advantages of Software Security Testing Services

The benefits of using software testing to ensure its safety are numerous. The advantages include, among others:

  • Find bugs that could compromise software security before releasing it.
  • Verify that the program satisfies all safety requirements.
  • Boost the safety of software in general.
  • Minimize the likelihood that software flaws may be exploited.
  • Data leakage prevention
