Defining Security Testing: What You Need to Know
A testing type of software testing that reveals vulnerabilities and pitfalls in a software operation prevents vicious attacks from interfering. The purpose of security tests is to spot all possible loopholes and sins of the software system that result in a loss of information, profit, or reputation at the hands of the workers or outlanders of the association. It's about discovering all possible faults in the system that might affect the loss of data or information in an organization. It helps detect all possible security pitfalls in the system and assists inventors in fixing these problems through coding.

Exploring Different Types of Security Testing
The below highlighted are the different types:
Cross-Site Scripting
Cross-site scripting (XSS) testing involves checking for vulnerabilities where attackers inject malicious scripts into web applications. This type of testing also ensures that user input is properly sanitized to prevent unauthorized access to sensitive data, like cookies.
Ethical Hacking
Ethical hacking is a type of security testing where professionals simulate cyberattacks to find weaknesses in a network or system. The goal is to identify vulnerabilities before malicious hackers can exploit them, enhancing overall system security.
Password Cracking Testing
Password cracking tests the effectiveness of password security measures in place. By attempting brute-force or dictionary attacks, testers identify weak passwords and areas where encryption or stronger authentication is required.
Penetration Testing
Penetration testing involves simulating an attack on a system to discover vulnerabilities. The goal is to assess the security posture of the system by attempting to exploit potential weaknesses, helping organizations understand where they are most at risk.
Ethical Hacking vs. Penetration Testing - While ethical hacking involves authorized attempts to exploit vulnerabilities to improve security, penetration testing specifically focuses on simulating real-world attacks to identify security weaknesses.
Risk Assessment Testing
Risk assessment testing involves identifying and evaluating potential threats to an organization's IT infrastructure. This type of security testing helps determine the likelihood and impact of vulnerabilities being exploited, guiding risk management decisions.
Security Auditing
Security auditing is a comprehensive review of an organization's security policies, procedures, and controls. The goal is to assess how well the system conforms to established security standards and identify areas for improvement.
Security Scanning
Security scanning uses automated tools to identify vulnerabilities in web applications, operating systems, and networks. It helps detect potential security threats early, allowing teams to take action before exploitation occurs.
SQL Injection Testing
SQL injection testing focuses on ensuring that applications are not vulnerable to attacks in which user input is maliciously used to manipulate the database. By entering certain characters into input fields, testers can confirm that the application properly sanitizes data to prevent unauthorized access.
Vulnerability Scanning
Vulnerability scanning involves using automated tools to detect known security risks within a network or application. This type of testing helps identify unpatched vulnerabilities and weaknesses that attackers could exploit.
Posture Assessment
Posture assessment combines multiple security testing techniques, including ethical hacking, risk assessment, and security scanning, to provide a comprehensive evaluation of an organization's security health. It offers a holistic view of an organization's readiness to defend against cyber threats.

Core Principles of Effective Security Testing
Security testing is crucial for identifying vulnerabilities and ensuring that your applications, systems, and networks are safeguarded against potential threats. Below are the key principles that should guide your security testing practices:
- Confidentiality: Ensure sensitive data is protected and accessible only to authorized users.
- Integrity: Confirm that data has not been altered or tampered with by unauthorized entities during transit or storage.
- Availability: Verify that systems and applications are available for authorized users, even during a potential cyberattack.
- Authentication and Authorization: Test mechanisms to validate that users are who they say they are and have appropriate access levels.
- Compliance: Security testing should always consider compliance with industry standards like GDPR, HIPAA, or PCI-DSS.
Important Techniques:
- DevSecOps: Integrating security testing within the DevOps pipeline for continuous security assurance throughout the development lifecycle.
- Application Security Testing (AST): Focuses on the security of applications, testing for vulnerabilities that could be exploited by attackers.
Importance of Security Testing in the Current Digital Era
Data Security of Customer
A significant reason startups deploy testing in their development model is to ensure the standards of their products/ services. These services very often collect and make extensive use of knowledge collected from the top clients/users. This knowledge is segregated into two parts: operational data and data stored within the repositories. If any one of those data is compromised, it creates an enormous problem for the organization because the data becomes public, and it poses a threat of misuse of that data.
Customer Confidence Matters
Users give critical & sensitive data on these applications & platforms and often depend on online banking & payment platforms to make transactions. The various Security breaches, whether major or minor, may lead to a loss in customers' confidence, honesty, and the organization's reputation, ultimately affecting the revenue.
Increase Product Quality
Debugging after a user has already encountered a problem is expensive. Still, it'll cost productivity, reputation, and consumer trust, and any startup can't afford to lose any of its very few customers. The latter is carefully analyzing what your product has to offer them.
Authentication
The authentication will cover the outbreaks, which aim to the application methods of validating the user identity, where the user account individualities will be stolen. Partial authentication will allow the attacker to access the functionality or sensitive data without performing the correct authentication.

Stages of Performing Security Testing
The several stages for its testing are described below:
Requirement Stage
The SDLC requirements phase performs a security analysis of business requirements to see which cases are operational and which are wasted.
Design Stage
During the SDLC design phase, security tests are conducted to investigate the risk of the design, and security tests are also embraced during the development of the test plan.
Development or Coding Stage
The SDLC coding phase runs white-box tests along with static and dynamic tests.
Testing Stage
During the SDLC testing phase, you need to perform a round of vulnerability scanning along with black-box testing.
Maintenance Stage
Within the maintenance phase of SDLC, we'll do the impact analysis of impact areas.

Techniques for Comprehensive Security Scanning
Static Application Security Testing (SAST)
SAST relies upon static analysis. This approach is the inside-out process. It is also known as white-box testing and simulates a developer's testing methodology. The tester is aware of all the underlying technologies and has access to the code, frameworks, libraries, binaries, algorithms, and implementations. In SAST, analyze the source code without running the application. Further, when using this approach, security vulnerabilities can be found during the earlier phase in the SDLC and are fixed before the application enters the testing phase. Furthermore, the tester needs to have advanced knowledge of the implementation, programming language, and technologies used. SAST can't detect runtime vulnerabilities.
Dynamic Application Security Testing (DAST)
DAST relies upon dynamic analysis. This approach is the outside-in approach. It is also known as black-box testing and simulates a hacker's testing methodology. In DAST, the application is executed and analyzed. The tester doesn't require access to source code and only needs running applications to test. With this approach's help, security vulnerabilities are found during the later phase of the SDLC and generally fixed in the next cycle, except for the critical vulnerabilities. The tester needs to have essential to intermediate knowledge of the implementation, programming language, and technologies used. DAST can detect runtime vulnerabilities.
Interactive Application Security Testing (IAST)
IAST combines SAST and DAST security testing techniques/approaches to address their drawbacks. It is a more focused approach to application testing. This approach uses the information present inside the application while running and requires the tester to perform analysis in real-time and during any phase of the development process. IAST integrates well with the CI/CD (continuous integration/continuous delivery). It also covers a broader set of testing rules than either SAST or DAST.

Overview of Various Security Testing Methods
The primary task in penetration testing is security testing. The target of Evaluation (ToE) is the resource, system, or environment. Categorise Security Testing into two major categories, which can further be classified into different types. The two major categories are:
Based on the Knowledge About the Environment
-
Black-Box Testing
In black-box testing, the tester is not knowledgeable about the target environment or its components. It simulates an external attack where the attacker doesn't have any information provided by the organization. The tester does not know the internal workings of the system and applications. The attacker's responsibility is to gather all necessary information about the target, including its security posture and vulnerabilities. It simulates a real-world testing approach that is taken by external attackers. In black-box testing, the tester spends more time gathering information about the target. It is not suitable for algorithm testing. It is the least exhaustive and least time-consuming, but it can be the most time-consuming in some cases.
Black-box testing can be performed by end-users, testers, and developers. However, testing of the data domain and internal boundaries is not possible with black-box testing. It is done using the trial-and-error method. It is opaque, and its granularity level is low. -
White-Box Testing
In white-box testing, the tester has complete knowledge of the target environment or its components. The organization provides all necessary information about the target, including documentation, security postures, and algorithms. The tester has full knowledge of the internal workings of the systems and applications. White-box Testing is a more structured approach, and the security tester reviews the information provided by the organization and verifies its accuracy. It simulates a system to which an internal attacker follows. In white-box testing, the tester spends more time searching for vulnerabilities and exploiting them. It is best suited for algorithm testing. It is the most exhaustive and most time-consuming.
The tester and developers are the ones who perform this testing. Testing of data domain and internal boundaries is possible with white-box testing. It is transparent. Its granularity level is high. It is also a clear-box Test, structural testing, or code-based testing. -
Gray-Box Testing
In gray-box testing, the tester has partial knowledge of the environment and its components, including some documentation and limited information provided by the organization. The tester is knowledgeable enough about the system's internal workings. It is not best for algorithm testing. It is partly exhaustive and average time-consuming. End-users, testers, and developers can perform it. Testing data and internal boundaries can be possible with gray-box testing if the organization provides the information. It is translucent and its granularity level is medium.
Based on the Pen Tester's Location
-
Internal Testing
In internal penetration testing, the tester or attacker performs the attack from within the organization's internal network. The attacker may be provided access to resources behind the firewall. This type of penetration testing simulates internal attacks that are carried out by a team member or stolen credentials. -
External Testing
In external penetration testing, the tester or attacker performs the attack on the organization's external or internet-facing resources. The attacker may or may not be allowed to physically enter the organization's premises during the entire process and perform the pen test from any remote location. This type of penetration testing simulates external attacks or cyber-attacks.

Based on the Method of Conduction
-
Manual Penetration Testing
Humans and required human interactions carry it out at every point in time. Experts or professionals perform it as different tools must be run manually on the interaction and results at different points. It requires multiple tools, and results can vary every time based on the type of tool used and the attack vector targeted. It is time-consuming and exhaustive both for the attacker and the resources, but it can be relied upon for critical resources. If the attacker uses manual penetration testing, he can explore the entire attack surface. There is a strong possibility of finding vulnerabilities that automated penetration Testing tools can't detect. It involves an analysis of obtained results at various levels and combining the insights to create the payload. The attacker creates the report after carrying out the pen-testing. Manual Penetration Testing is generally beneficial in the case of external testing. -
Automated Penetration Testing
It is carried out with the help of automatic tools that require very little human interaction. Any learner can perform it as everything is automatic, and the tester just needs to know how to configure the scan. It has all the tools in it, and the results are fixed as only a fixed set of predefined tests are run and attack vectors are tested. It is fast and more efficient but is not completely reliable. If the tester uses automatic penetration testing, the tester gets the report at the end of the scan or test, and only the tests present in the tool's database are carried out. Analyze the report manually by tester. Automatic penetration testing is generally helpful in internal testing using various penetration testing tools.
Based on Intimation
-
Blind Testing
In Blind testing, the tester has only the name of the target organization. This is necessary to get an analysis from a black-hat hacker perspective. Along with this, it replicates a real-attack scenario and helps the organization's security personnel get insights to improve their security posture. -
Double-Blind Testing
In double-blind testing, the attacker or tester is only provided with the name of the target organization. The organization's security personnel are not aware that a stimulative attack (penetration testing) is going to happen. It helps to check the organization's readiness and test their defense strategies as the attack is in real-time, and the security team has no time to prepare for the attack. -
Targeted Testing
In targeted testing, the tester or attacker and the organization's security personnel work together and update each other about their progress. This provides the security team with real-time feedback and insights from a hacker's perspective. Targeted testing is a security training program.
