What is Security Testing? (Types with Examples)
What is the Purpose of Security Testing?
Security testing is a sort of software testing that identifies vulnerabilities, hazards, and dangers in a software program and guards against intruder assaults. The goal of security tests is to find any potential flaws and vulnerabilities in the software system that might lead to a loss of data, income, or reputation at the hands of workers or outsiders.
What are the Benefits of Security Testing?
The basic purpose of security testing is to find and assess possible vulnerabilities in a system so that attacks may be faced and the system does not cease working or be exploited. It also aids in the detection of any potential security vulnerabilities in the system, as well as assisting developers in the resolution of issues via code.

Security Testing Types
According to the Open Source Security Testing methodology document, there are seven basic forms of security testing. The following are the explanations −
Vulnerability Scanning − This is done by scanning a system against known vulnerability signatures using automated tools.
Security Scanning − entails discovering network and system flaws and then proposing remedies to mitigate the risks. This scanning may be done in two ways − manually and automatically.
Penetration testing − This kind of testing replicates a hostile hacker's attack. This testing entails examining a specific system for possible vulnerabilities in the event of an external hacking attempt.
Risk Assessment − This kind of testing entails analyzing the security threats that have been identified in the company. There are three levels of risk: low, medium, and high. This testing suggests risk-reduction controls and procedures.
Security Auditing − This is an internal check for security issues in applications and operating systems. A line-by-line examination of code may also be used to conduct an audit.
Hacking an organization's software systems is referred to as ethical hacking. Unlike criminal hackers who steal for personal benefit, the goal is to uncover system security problems.
Security scanning, ethical hacking, and risk assessments are combined in a posture assessment to reveal an organization's overall security posture.
How to Test for Security
It is universally acknowledged that deferring security testing until after the software implementation process or after deployment would increase costs. As a result, security testing must be included early in the SDLC life cycle.
Let's have a look at the security procedures that should be used for each step of the SDLC.
|SDLC Phases||Security Processes|
|Requirements||Check for abuse/misuse incidents and do a security analysis.|
|Design||For designing, do a security risk analysis. Creating a test plan that includes security tests|
|Coding and Unit Testing||Security and Static and Dynamic Testing Testing in a White Box|
|Integration Testing||Black Box Testing|
|System Testing||Vulnerability scanning and black box testing|
|Implementation||Vulnerability Scanning, Penetration Testing|
|Support||Analyze the Impact of Patches|
The test strategy should contain the following −
Security-related scenarios or test cases
Data pertaining to security testing
Security testing necessitates the use of test tools.
Analyzing numerous test results from various security technologies
Examples of Security Testing Scenarios
Sample test scenarios to give you an idea of the kind of security tests that are available −
A password must be stored in an encrypted way.
Invalid users should not be allowed to access the application or system.
For application, check cookies and session time.
The browser back button should not operate on financial sites.
Security Testing Methodologies, Approaches, and Techniques
Different approaches are used in security testing, and they are as follows −
Tiger Box − This kind of hacking is often done on a laptop with a variety of operating systems and hacking tools. This testing aids penetration testers and security testers in assessing and attacking vulnerabilities.
Black Box − The tester is permitted to test the network architecture and technologies in general.
Grey Box − A combination of white and black box models in which the tester is provided only partial knowledge about the system.
Roles in Security Testing
Hackers − Unauthorized access to a computer system or network
Crackers − Infiltrate computer systems in order to steal or destroy data.
Ethical Hacker − Performs the majority of the breaking actions with the owner's approval.
Script kids or packet monkeys are inexperienced hackers who know how to program.

Wireshark, formerly known as Ethereal, is a network analysis tool. It catches packets in real-time and displays them in a way that is understandable to humans. It's essentially a network packet analyzer that gives you minute data about your network protocols, decryption, packet information, and so on. It's free and open-source, and it works with Linux, Windows, OS X, Solaris, NetBSD, FreeBSD, and a variety of other operating systems. The information acquired by this utility may be examined using a GUI or the TShark Utility in TTY mode.
W3af is a framework for web application attack and auditing. It has three types of plugins: discovery, audit, and attack, which communicate with one another to find any vulnerabilities in the site. For example, a discovery plugin in w3af looks for different urls to test for vulnerabilities and forwards them to the audit plugin, which then searches for vulnerabilities using these URLs.
Security Testing Myths and Facts
Let's have a look at some intriguing security testing myths and facts −
Myth #1 − Because we have a tiny firm, we don't need a security policy. Fact: Every individual and corporation need a security policy.
Myth #2 − Security testing has no return on investment.
Fact − Security testing may identify areas where efficiency and downtime can be improved, allowing for maximum throughput.
Myth #3 − Unplugging it is the only way to safeguard it.
Fact − Finding "Perfect Security" is the only and best technique to safeguard an organization. By doing a posture assessment and comparing it to commercial, legal, and industry grounds, perfect security may be accomplished.
Myth #4 − The Internet is a dangerous place. I'll buy software or hardware to protect the system and rescue the company.
Fact − Purchasing security software and hardware is one of the most difficult tasks. Instead, the company should first learn about security before implementing it.
The most critical testing for an application is security testing, which ensures whether secret data remains confidential. In this sort of testing, the tester takes on the role of an attacker and explores the system in search of security flaws. Security testing is critical in software engineering because data must be protected at all costs.
It is vital to undertake security testing on an application or program to ensure that sensitive data remains secret. Security testing is critical in software testing since it allows us to keep our vital data in the end. In this scenario, the test engineer will impersonate an intruder and test the system or look for security flaws.
