What is vulnerability scanning?
Vulnerability scanning is the action of conducting an automated review of your system to look for potential risks and vulnerabilities. For budding information security professionals (or even those who have worked in the field for years), there is always something new to learn. Not only is it a highly intricate and advanced field but, on a daily basis, there is a cat-and-mouse game happening between security engineers and hackers. Engineers look for new ways to secure their systems, hackers look for new ways to break those security measures, and the cycle goes on and on.
You don’t have to know every vulnerability or risk out there, though, because there are tools that do it for you. This is the magic of vulnerability scanning.
What does vulnerability scanning mean?
Think of it as a scan to check for any unlocked doors that a thief could use to get in or to get access to your confidential data. Vulnerability scanning is a vital part of a strong security posture, and it’s even required for compliance with certain security standards and certifications.
What is a vulnerability scanner?
A vulnerability scanner is a tool that performs an automated vulnerability scan for your system. There are numerous different vulnerability scanners on the market, and each one has its own processes and covers different digital assets. It’s important to understand what your system entails so you can examine various vulnerability scanners to find the best fit.
What is a vulnerability scan?
The term “vulnerability scan” can be used in a few different ways. It can refer to the process of scanning for vulnerabilities, such as, “We’re running a vulnerability scan today.” Or, it can refer to the report you receive as a result of the scan, such as, “According to our vulnerability scan, these are the issues we need to address.”
Types of vulnerability scans
Vulnerability scanning doesn’t vary from one brand to another. There are different types of scans you can choose to perform based on what you want to know about your system. Most noticeably, you’ll see options for internal vs. external vulnerability scans and authenticated vs. unauthenticated vulnerability scans.
Internal vs. external vulnerability scans
Proper data security involves not only locking down your system from access by unauthorized users but also locking down sensitive, confidential data on a need-to-access basis. Internal and external vulnerability scans assess your security from both of these angles.
An internal vulnerability scan is conducted from within your network. The goal is to find any vulnerabilities that could be exploited by an internal user like an employee. An external vulnerability scan, on the other hand, is conducted from outside your network to find vulnerabilities that could be exploited from outside the network.
The most comprehensive choice, of course, is to perform both internal and external scans. In fact, this is required for some security standards like PCI DSS.
Authenticated vs. unauthenticated vulnerability scans
Another distinction that can be made between vulnerability scans is authenticated vs. unauthenticated vulnerability scans. An authorized vulnerability scan is a scan conducted using valid log-in credentials for your system to see what a logged-in user could access and how they could move through your system. An unauthorized vulnerability scan, on the other hand, evaluates what a person could access if they weren’t able to get valid log-in credentials.
Note that you might also see the terms “credentialed vulnerability scan” and “non-credentialed vulnerability scan.” These are used interchangeably with authenticated and unauthenticated vulnerability scans.
How is vulnerability scanning different from penetration testing?
Vulnerability scanning may sound similar to another type of security evaluation technique called penetration testing. After all, they are both ways to assess your security posture and identify missing pieces and opportunities for problems. They work in different ways, though.
In vulnerability scanning, an automated tool performs a scan of your system to look for known vulnerabilities from its database. It’s all about finding security gaps that a hacker could hypothetically exploit.
In penetration testing, on the other hand, a hired expert runs through operations to try to hack into your system and access confidential data.
How does vulnerability scanning work?
A vulnerability scanner works by using a database of known vulnerabilities and looking for these vulnerabilities in your system. It checks various interfaces and runs various scenarios within your system to identify any potential risks. The best part is that this is all done on an automated basis, so it’s hands-off for your team.
Is vulnerability scanning a requirement?
For most organizations, vulnerability scanning is a voluntary way to keep your data and your infrastructure secure. It is, however, a requirement for compliance with certain security standards like PCI DSS.
In addition to this, there are other standards that don’t necessarily require vulnerability scanning by name, but they do require you to have a process in place for identifying vulnerabilities. Vulnerability scanning is an efficient and reliable way to meet that requirement.
Why is vulnerability scanning important?
Protecting your organization and your clients’ data needs to be an ongoing effort, and there are always new vulnerabilities that may arise. To keep your data secure, you need to have a way to detect these vulnerabilities when they appear and resolve them promptly.
A vulnerability scanner doesn’t only give you a reliable way to do this but it also takes the manual work off your hands. It’s always a good idea to stay on top of the latest news about discovered vulnerabilities, but a vulnerability scanner ensures that you don’t need to check your system manually; if there is an opportunity for hackers, it will alert you.
