Software Testing - Brief Introduction To Security Testing

Security testing is an important process in order to ensure that the systems/applications your organization is using, meet the set security policies and are free from any type of loopholes, that can cause any loss to your organization.

Security Testing of any developed system is all about finding the potential loopholes and weaknesses of the system, which might result into loss/theft of highly sensitive information or destruction of the system by an intruder/outsider. It helps in finding out all the possible vulnerabilities of the system and helps developers in fixing those problems.
Need
  • A security test helps in improving the current system and also helps in ensuring that the system will work for a longer period of time .
  • It doesn't include conformance of resistance of the systems your organization uses, it also ensures that people in your organization understand and obey the security policies in place.
  • If involved right from the first phase of software development life cycle, it can help in eliminating the flaws in the design and implementation of the system, and in turn help the organization in blocking the potential loopholes in the earliest possible stage. This is beneficial to the organization almost in all aspects.
Who needs Security Testing?
These days, almost all organizations across the world are equipped with hundreds of computers connected to each other through intranets and various types of LANs inside the organization itself, and through Internet with the outer world. They are also equipped with data storage and handling devices.
The information that is stored in these storage devices and the applications that run on the computers are highly important to the organization from the business, security, and survival point of view.
Any organization, small or big in size, needs to secure the information it possesses and the applications it uses, in order to keep its customer's information safe and suppress any possible loss of its business.
Types
Security Auditing
It includes direct inspection of the application developed and Operating Systems and any system on which it is being developed. This also involves a code walk-through.
Security Scanning
It is all about scanning and verification of the system and applications. During security scanning, auditors inspect and try to find out the weaknesses in the OS, applications, and network(s).
Vulnerability Scanning
Vulnerability scanning involves scanning of the application for all known vulnerabilities. This scanning is generally done through various suitable software.
Risk Assessment
It is a method of analyzing and deciding the risk that depends upon the type of loss and the probability of loss occurrence. It is carried out in the form of various interviews, discussions, and analysis of the same. It helps in finding out and preparing a possible backup-plan for any type of risk, hence contributing towards the security conformance.
Posture Assessment and Security Testing
This is a combination of Security Scanning, Risk Assessment, and Ethical Hacking, in order to reach a conclusive point and help your organization know its stand with context to safety.
Penetration Testing
This type of tester tries to forcibly access and enter the application under test. It may try to enter into the application/system with the help of some other application or with the help of combinations of loopholes that the application has kept open unknowingly. It is the most effective way to practically find out potential loopholes in the application.
Ethical Hacking
It's a forced intrusion by an external element into the system that is being tested.
(Please Note: The mentioned types  is based on the Open Source Security Testing Methodology Manual of Pete Herzog and the Institute for Security and Open Methodologies - ISECOM)
The best way to ensure safety is to involve the security related assessments, audits, and various types of testing, right from the first phase of system development. The level and form of processes used in security testing of any system varies depending upon its phase, condition, and type.
