Software testing Vs Cyber security
In today’s digital age, software testing and cyber security have become two essential pillars of software development. While both of these fields are important in their own right, they serve different purposes and require different skill sets. Understanding the differences between software testing and cyber security is crucial to ensure that your software is not only functional, but also secure from cyber threats.
Software Testing
Software testing is the process of evaluating a software application or system to identify defects or errors that may prevent it from functioning properly. The goal of software testing is to ensure that the software meets its intended requirements and specifications, and performs as expected in different scenarios and environments. Testing can be conducted at various stages of the software development lifecycle, from unit testing to acceptance testing.
There are several types of software testing, including functional testing, performance testing, security testing, and usability testing. Each type of testing is designed to address specific aspects of the software and identify potential issues. For example, security testing is focused on identifying vulnerabilities and weaknesses that could be exploited by cyber attackers.

Cyber Security
Cyber security, on the other hand, is the practice of protecting computer systems, networks, and data from unauthorized access, theft, or damage. Cyber security aims to ensure the confidentiality, integrity, and availability of information and systems, and prevent cyber attacks that can cause financial, reputational, or operational damage to organizations.
Cyber security encompasses various disciplines, including network security, application security, information security, and cloud security. Cyber security professionals use a range of tools and techniques to detect, prevent, and respond to cyber threats, such as malware, phishing, ransomware, and social engineering.
Examples
To illustrate the differences between software testing and cyber security, let’s consider two examples:
Example 1: A software application that processes online payments
Software testing: In the testing phase, the application is tested to ensure that it can process payments accurately and securely. Testing may include functional testing to verify that payment information is captured correctly, performance testing to ensure that payment processing is efficient and timely, and security testing to identify vulnerabilities that could be exploited by hackers.
Cyber security: In the cyber security phase, the application is assessed for vulnerabilities that could be exploited by cyber criminals to steal payment information, such as credit card numbers and personal identification numbers (PINs). Cyber security measures may include encryption to protect payment information, firewalls to prevent unauthorized access, and intrusion detection systems to monitor for suspicious activity.
Example 2: A mobile banking application
Software testing: In the testing phase, the mobile banking application is tested to ensure that it functions properly on different mobile devices and operating systems. Testing may include usability testing to ensure that the user interface is easy to navigate, and security testing to identify vulnerabilities that could compromise user data.
Cyber security: In the cyber security phase, the mobile banking application is assessed for vulnerabilities that could be exploited by cyber criminals to gain unauthorized access to user accounts and steal sensitive information, such as banking credentials and personal data. Cyber security measures may include two-factor authentication to verify user identity, encryption to protect user data, and secure coding practices to prevent common vulnerabilities such as SQL injection and cross-site scripting (XSS).
In summary, software testing and cyber security are two distinct but complementary fields that are essential to the success of software development. Software testing ensures that software applications are functional and perform as expected, while cyber security ensures that software applications are secure and protected from cyber threats. By understanding the differences between software testing and cyber security, software developers can design and develop software applications that are not only functional, but also secure and resilient to cyber attacks.
