What is security testing in software testing?
Security Testing is a form of software testing that detects vulnerabilities, hazards, risks in a software application and prevents malicious attacks from intruders. Security Testing aims to locate all potential vulnerabilities and weaknesses in the software system that could result in a loss of information, income, and credibility in the hands of employees or outsiders of the Company.
Importance of Security Testing services
The main purpose of Security Testing is to identify the threats to the system and to measure its possible weaknesses so that threats can be identified and the system does not stop working or cannot be abused. It also helps identify all potential security risks in the system and helps developers to solve problems by coding.
Security Testing Types:
There are seven key forms of security testing in the Open Source Security Testing Services Methodology Manual. It is clarified as follows:
- Vulnerability Scanning: This is achieved using automated software to search the device against known signature vulnerabilities.
- Security Scanning: It includes finding network and device vulnerabilities, and then presenting solutions to reduce these risks. This scan can be done for both Manual and Automated scanning.
- Penetration Testing: This form of testing simulates an attack by a malicious hacker. This testing requires an inspection of a specific device to check for possible flaws in an external hacking attempt.
- Risk assessment: This test includes an overview of the safety threats found in the company. Risks are graded as low, medium, or strong. This test suggests controls and risk-reduction measures.
- Security auditing: this is an internal review of security flaws in software and operating systems. The audit may also be carried out by line inspection of the code
- Ethical manipulating: it’s hacking the information systems of the enterprise. Unlike malicious hackers who steal for their benefit, the aim is to reveal security vulnerabilities in the system.
- Posture assessment: This incorporates security screening, ethical hacking, and risk assessment to demonstrate the overall safety status of the company.
Desktop & Website Security Testing services
A desktop application should be safe not only in terms of its access but also in terms of the organization and storage of its data.
In the same way, web applications need even more security concerning their access, as well as data protection. The web developer should have the framework resistant to SQL Injections, Brute Force Attacks, and XSS (cross-site scripting). Similarly, if the web application requires remote access points, they must also be secure.
The Open Web Application Protection Project (OWASP) is a global non-profit organization focused on enhancing software security. The project has several tools to test different software environments and protocols. Project flagship tools include:
- Zed Attack Proxy (ZAP – an integrated penetration testing services India)
- Check of OWASP Dependency (it scans for project dependencies and checks against know vulnerabilities)
- Project for OWASP Web Testing Environment (collection of security tools and documentation)
Wireshark is a network analysis method formerly known as Ethereal. It collects packets in real-time and shows them in a human-readable format. It’s a network packet analyzer, which offers the minute details of your network protocols, decoding, packet information, etc. It’s an open-source that can be used on Linux, Windows, OS X, Solaris, NetBSD, FreeBSD, and many other systems. The information that is extracted from this tool can be accessed via a GUI or TTY TShark Utility.
W3af is an assault and audit platform for web applications. It has three types of plugins; discovery, audit, and attack that interact with each other for any weaknesses on the web, e.g. a discovery plugin in w3af searches for various URLs to test for vulnerabilities and forwards it to the audit plugin that then uses these URLs to check for vulnerabilities.
Security Testing Techniques:
1. Access to the program
If it is a software application or a website, ‘Roles and Rights Management’ implements access control. This is also achieved indirectly when covering features,
For example, in the Hospital Management System, the receptionist is least concerned about the laboratory tests, because his role is simply to register the patients and arrange appointments with the doctors.
Several user’s accounts with different and multiple functions should be generated by the tester. It can then use the application with the aid of these accounts and check that each function has access to its modules, screens, forms, and menus only. If the tester detects a discrepancy, the security problem should be logged in with full trust.
2. Data security
There are three facets of data protection. The first is that only the data that the user is expected to use can be accessed or used. Roles and privileges are therefore guaranteed
For example, the company’s TSR (telesales representative) can display the data on the current supply, but cannot see how much raw material was bought for development.
All confidential data must be encrypted to keep it safer. Encryption should be solid, particularly for sensitive data such as user account passwords, credit card numbers, or other business-critical information.
3. The brutal-force assault
Brute Force Assault is often achieved with certain automated methods. The idea is that by using a legitimate user ID, the program seeks to guess the associated password by attempting to log in again and again.
A basic example of protection against such an attack is the suspension of accounts for a limited period, as all mailing applications such as ‘Yahoo,’ ‘Gmail’ and ‘Hotmail’ do.
4. Injection of SQL and XSS (Cross-Site Scripting)
Conceptually speaking, the theme of each of these hacking attempts is identical, so they are discussed together. In this method, the malicious script is used by hackers to exploit the website.
There are a variety of ways to immunize against such attempts. For all input fields of the website, the length of the field should be specified small enough to limit the input of any script.
Security testing is the most critical test for an application and tests whether sensitive data remains confidential. In this form of testing, the tester plays the part of the intruder and plays a role in detecting security-related bugs across the device. Security Testing in Software Engineering is very important for the safety of data by all means.
