Running a business isn\u2019t easy, and potential data breaches make it even more challenging. Information related to your client, coding, revenue, and employees is crucial. That\u2019s why regular <\/span>penetration testing<\/span><\/a> is so important. The goal is to uncover vulnerabilities by performing an actual cyberattack on your system.<\/span><\/p>\n\n\n\n

According to the style and approach, the three <\/span>types of penetration<\/b> testing are black box<\/b> testing, gray box testing, and white box testing. Let\u2019s discuss and compare them in detail. <\/span><\/p>\n\n\n\n

Black Box Testing<\/h2>\n\n\n\n

A black box penetration test<\/b>, also known as an external penetration test, is performed when a white-hat hacker has no prior information about the security policies, architecture diagram, source codes, etc. of your IT structure. Conducting a <\/span>penetration test step by step <\/span>this way mimics the actions of a real-life cyberattacker. .<\/span><\/p>\n\n\n\n

In<\/span> black box penetration test methodology<\/b>, the company allows white-hat testers to impersonate an unprivileged black-hat attacker. It\u2019s like an actual cyberattack, so it gives you the best idea about your system\u2019s vulnerabilities. <\/span><\/p>\n\n\n\n

The white-hat tester creates a map of attack and all the entry points (just like a black-hat hacker) for observation and analysis required to hit your system. <\/span><\/p>\n\n\n\n

The benefit of the <\/span>black box penetration testing methodology<\/b> is its ability to detect complex vulnerabilities like cross-site scripting (also known as XSS, which enables threat actors to disrupt the operation of web pages), SQL injections, server misconfiguration, etc. XSS.  <\/span><\/p>\n\n\n\n

Now that you\u2019re fairly aware of <\/span>what a black box penetration test is<\/b>, let\u2019s move to the next testing approach.<\/span><\/p>\n\n\n\n

Gray Box Testing<\/h2>\n\n\n\n

So, what is a gray box<\/b> penetration test? <\/b>Unlike <\/span>black box penetration testing<\/b>, the tester has basic knowledge about your system, applications, and network. With <\/span>gray box penetration testing<\/b>, the tester gets low-level credentials, network maps, and logical flow charts<\/a>. <\/span><\/p>\n\n\n\n

This saves time consumed in various <\/span>stages of penetration tests<\/span>. <\/span>Gray box penetration testing<\/b> is helpful as some vulnerabilities can only be found by looking at source codes. Such susceptibilities are left unidentified in <\/span>a black box penetration test<\/b>.<\/span><\/p>\n\n\n\n

White Box Testing<\/h2>\n\n\n\n

The easy <\/span>white box penetration testing definition<\/b> is as follows: It\u2019s a style of testing in which the tester is privileged to get all your system\u2019s information. This means they already have credentials, source codes, infrastructure maps, and all that\u2019s required to attack your system. <\/span><\/p>\n\n\n\n

The <\/span>white box penetration testing technique <\/b>is basically applied to spot potential weaknesses. This can be a poorly written code, or absence of robust security measures.<\/span><\/p>\n\n\n\n

Testers prefer using the white box approach for high-risk systems only as it takes time. Nonetheless, it still efficiently fulfils the <\/span>goals of a penetration test<\/span>.<\/span><\/p>\n\n\n\n

Black Box vs. White Box vs. Gray Box Penetration Testing<\/h2>\n\n\n\n

Let\u2019s compare <\/span>black box vs. gray box vs. white box penetration testing<\/b>. This will help you decide the most appropriate technique as per your expectations, budget, and requirements. Knowing the differences also gives you insights on using the right <\/span>penetration testing tools<\/span> in future.<\/span><\/p>\n\n\n\n
