Penetration testing is kind of Security Testing used to check the unprotected portions of the system or applications. The goal of this testing is to find all security vulnerabilities that are existing in the system being tested. Vulnerability is the possibility that a cyber-attacker can interrupt or gain authorized access to the system or any data contained within it. It is also called pen test or pen testing.
Vulnerabilities are usually introduced by problems during software development and implementation phase. Common vulnerabilities include software bugs, configuration errors, design errors etc.
Penetration is essential in an enterprise because
Banks, Investment Banking, and Stock Trading Exchanges and other financial sectors want penetration testing for secure their data and is also essential to ensure security
In case if the software system was hacked already and organisation wants to determine whether any threats are still available or not in the system to avoid future hacks.
Proactive Penetration Testing is the best security against hackers.
Types of Penetration testing:
The type of penetration test selected usually depends on the scope and whether the organisation wants to simulate an attack by an Employee, by External Sources, or by Internal Sources. There are three types of Penetration testing and they are
- Black Box Testing
- Grey Box Penetration Testing
- White Box Penetration testing
In black box penetration testing, the tester has unknown about the systems to be tested. They are responsible to gather information about the target system or network.
In a grey box penetration testing, the tester is given partial knowledge of the system or network. It can be considered as an attack by an external hacker who had gained illegitimate access to an organization’s network infrastructure documents.
In a white-box penetration testing, the tester is usually given complete information about the system or network to be tested, including the OS details, IP address schema, source code etc. This can be considered as a simulation of an attack by any internal sources.
Penetration Testing cannot find all vulnerabilities in the system. There are limitations of time, budget, scope, skills of Penetration Testers
The following will be common effects when tester is doing penetration testing:
- Down Time
- Data Loss and Corruption
- Increase costs
Role and Responsibilities of Penetration Testers:
The penetration Tester job is to:
- Testers should gather essential information from the Organization to enable penetration tests
- To Find flaws that could enable hackers to attack a target machine
- Pen Testers should act & think like a real hacker albeit ethically.
- Work by Penetration testers should be logically done so that it will be easy for developers to fix it.
- Start date and End date of test execution should be defined in advance.
- Testers should be responsible for any loss in the system or information during the testing
- Testers should keep data and information private.
