Penetration testing (also known as “pen” testing) is what happens when a business hires an ethical hacker to find and exploit their cybersecurity vulnerabilities.
Much like running an office fire drill, penetration testing provides a heads-up about potential issues, so you can figure out a way to address problems before the real thing happens.
Curious whether this might be a good idea for your organization? This article helps you understand precisely what pen testing is and isn’t, types of testing, and potential pitfalls.
TL;DR: Penetration testing is when you hire an ethical hacker to hack your business and see how much damage they could cause. It’s a weird idea, but it can really help you see how a hacker would approach your systems. Contact Interplay to learn more.
Take a moment to think about all the computers and devices your organization uses, all the local and cloud applications you run on each of those devices, all the peripherals attached to your network like printers and scanners and phones, and all the background network equipment you have like servers and routers and switches.
Has your brain started to hurt yet?
When you start to dive into the complexity behind IT systems, it quickly becomes clear that even the smallest in-office setups are sprawling hulks of interconnected systems. They have a lot of “unknown unknowns.”
Penetration testing, the practice of hiring an ethical hacker to break into your systems, brings those unknown unknowns to light so you can fix them.
The idea of hiring a hacker to break into your systems may sound foolhardy (and sometimes it is, if you hire the wrong one). However, much like hiring a thief to break into your bank vault, watching what the intruder does and how they try to circumvent your systems can provide you with a lot of great ideas on how to better secure your data and equipment.
We’ve all heard news stories about friendly hackers who reach out to people or businesses to point out security flaws that need to be fixed. A recent example of this was when a reporter discovered an online flaw that exposed school employees’ Social Security Numbers to the public. The newspaper reached out and told the state’s Department of Elementary and Secondary Education about the flaw, and the state repaired it.
This is NOT an example of penetration testing.
Although this situation identified a cybersecurity flaw in a no-consequence environment that the state could repair before a cyberattack happened, the state did not hire the reporter to find that flaw, so it was not an example of penetration testing.
Remember: if someone reaches out to your company and says they’ve found a flaw with your cybersecurity, this is NOT an example of penetration testing. (Don’t scoff. Strangely, this is a relatively common event. If they contact you, please contact your Managed Services Provider before doing anything… just in case.)
Another example of something that is NOT penetration testing is a Network Vulnerability Scan. Though a scan is a great first line of defense that can give you the 10,000-foot view of all the potential issues with your systems, it isn’t an actively simulated attack like penetration testing.
Now that we’ve got that covered, we can talk about the types of penetration testing.
In general, there are three main types of testing available:
Sometimes the IT team knows about the test in advance – sometimes they are given no advance notice. In cases where they have no advance notice, the penetration testing exercise can also analyze IT’s response to the issue in real time.
A hacker may also try to find the vulnerabilities in multiple systems. They may test your:
While penetration testing can be extremely beneficial to a company, there can be some drawbacks.
If you’re interested in running a penetration test for your organization, you can avoid these flaws by limiting what tools a hacker can use, or what systems they’re allowed to go after. You can cut down on the cost by deploying AI to simulate a real penetration test instead of hiring a real-live hacker.
