API Penetration Testing: What Is It, Importance, Best Tools, and More
If you are working a enterprise, it is necessary to ensure that your information is protected. One strategy to assess the safety of an API is by performing penetration testing. But what’s API penetration testing, why do you want it and which instruments are one of the best for you you utilize? Here, within the following article, we’ll focus on all of this in better element.
We’ll begin with a definition of API penetration testing, and then transfer on to the significance of defending your information. Next, we’ll check out a number of the greatest API penetration testing instruments in the marketplace.
What Does API Penetration Testing Mean?
API safety testing is the method of inspecting Application Programming Interfaces to ensure they’re safe from vulnerabilities. You can check manually or by means of automation, however automated API safety instruments often enable you work quicker and extra precisely.
API safety refers back to the means of making certain your API calls and endpoints are shielded from potential attackers, in addition to constructing APIs which are extra proof against common safety dangers.
API Penetration Testing: Why do You Need It?
API penetration testing is significant as a result of it may find weaknesses in your system earlier than they’re taken benefit of. By discovering and fixing these vulnerabilities, you possibly can stop information breaches, id theft, and different kinds of assaults.
In addition to stopping assaults, API penetration testing may enable you enhance the general safety of your system. By figuring out weaknesses in your API design or implementation, you may make modifications that may make it tougher for attackers to take advantage of these weaknesses.
Best API Penetration Testing Tools on the Market
Now that we have answered the query “what’s API penetration testing,” let’s check out a number of the greatest instruments in the marketplace.
- Astra Security
- Postman
- Assertible
- Katalon Studio
API Penetration Testing Step-by-Step Process
Now that we have appeared on the definition of API penetration testing and a number of the greatest instruments in the marketplace, let’s focus on the right way to truly carry out API penetration testing. Here is a step-by-step course of:
Test for API Input Fuzzing
Fuzzing the API refers to feeding the API random information and observing something uncommon within the output. This could possibly be data, an error message, or some other factor that might recommend the API processed that particular information.
Examine for API Injection Attacks
- SQL Injection
SQL injection, which is the usage of a SQL assertion to execute arbitrary instructions or alter information, and parameter tampering are probably the most frequent injections. By injecting malicious code into an API that employs SQL databases, hackers can acquire entry to delicate information or run unapproved instructions on the database.
- XML Injection
Another kind of injection assault is XML Injection, by which the attacker tries to get entry to or modify essential information stored in XML information. This targets APIs that use XML to retailer and course of information.
- Command Injection
By utilizing several types of working system instructions, you possibly can ship API enter to a different location. Keep in thoughts that these directions will solely run as they need to when you have a corresponding Operating System put in; for instance, Linux customers can kind “rm /” to eradicate a complete root listing whereas Windows customers would want to enter different command units.
Test for Parameter Tampering
API request values are sometimes simply manipulated. For instance, an attacker would possibly change the worth of a product to $0.00, primarily permitting them to get the product totally free.
Test for Unhandled HTTP Methods
Web apps which are API-enabled incessantly make use of quite a lot of HTTP strategies. These HTTP operations are used for saving, deleting, and acquiring information. A failure to load a specific API perform implies that until the server is up and working, it won’t be accessible.
You can check your API endpoint for authentication vulnerabilities by making a HEAD request. You can ship HEAD requests utilizing varied strategies.
Looking on the Best API Penetration Testing Tools in Depth
Astra’s pentest
Astra Pentest is a well-liked API penetration testing resolution that may execute 3000 checks to determine flaws in APIs. Astra Pentest has the next excellent options:
- Comprehensive Vulnerability Scanning: Astra’s complete vulnerability scanner can determine safety flaws based mostly on publicly accessible CVEs, the OWASP Top 10, and different broadly accepted standards. The newer ones embrace Intel Vulnerability Manager (Intel VAM)
- Regular Penetration checks: The Astra Pentest API testing resolution helps organizations maintain their APIs protected from vulnerabilities by recurrently testing for them and rapidly fixing any which are discovered. This approach, confidential information is much less prone to be stolen or manipulated by a malicious attacker.
- Rescanning: Rescanning is a standout service accessible by means of Astra Pentest, which presents one other scan to make sure that no new flaws have appeared because of the fixes applied all through an API check and vulnerability restore.
- Pentest Certificate: After the rescan is completed and any new bugs if any have been found, Astra Pentest delivers a publicly verifiable certificates to its purchasers confirming that the check has been accomplished efficiently. This certificates could enhance your organization’s popularity and entice extra prospects.
- Zero False Positives: The workforce of professional pentesters at Astra Security ensures zero false positives in vulnerability detection. We totally vet all automated pentest outcomes to make sure accuracy and reliability.
Postman
Postman is a well-liked device for creating and testing APIs, with over 17 million customers at 500,000 companies. It’s been round as a browser plugin since 2013 and has advanced right into a SaaS platform or a desktop program suitable with Windows, Linux, and macOS.
API requests and examples might be organized, grouped, reused, and shared in Postman collections. This allows collaboration between customers, automated testing of the API, and request chaining. Monitors might be connected to the gathering in order that they run automated checks as incessantly as each 5 minutes. These screens will alert customers if there are potential issues with the API.
Assertible
Assertible is a robust and easy-to-use assertion device that means that you can check your API‘s varied options with no code. Assertions might be as easy or advanced as you want them to be, from automated checks to customized checks. Turnkey assertions can also be used for issues like JSON schema validation and information integrity checks, due to the JSONPath language assemble.
It works with quite a lot of growth and communication instruments, together with GitHub, Slack, PagerDuty, and Zapier, in addition to steady integration and supply platforms. Test variables could also be collected by way of setup steps by which HTTP requests are chained collectively to permit for extra difficult testing situations.
Katalon Studio
Katalon Studio is not your typical check automation device. Not solely could it automate APIs, internet, cell and desktop apps on Windows, Linux, and macOS; it additionally does so on all three working methods! This makes Katalon Studio one of the vital standard and versatile check instruments in recent times. With particular assist for SOAP and REST requests in addition to cross-platform compatibility, data-driven testing has by no means been simpler to execute with instructions that learn from a number of information sources concurrently.
Conclusion
Any group that exposes its APIs to the general public ought to critically penetration check its API for safety measures. By recurrently testing for vulnerabilities and rapidly fixing any which are discovered, firms can reduce the chance of confidential information being stolen or manipulated by a malicious attacker. There are quite a lot of totally different instruments accessible in the marketplace for API penetration testing, every with its personal distinctive options and benefits.
