What Does Nessus Do?

There are many scanners that look for vulnerabilities in websites, but Nessus is one that the pros here at Be Structured love to rely on. Nessus assesses for vulnerability and provides penetration testing. This lets us look around your system and server for malicious attacks or open areas that need addressing. Tenable Security is the company behind Nessus, and they have created a tool that is effective at many different levels. The professional version of Nessus is commonly used in the IT field because of how quickly it can assess and discover problem areas within your networks. It can also create a target profile, audit the configuration of your network, detect if you have malware present, discover if sensitive data is adjusted improperly or missing, and even scan the programs you use within your system.

Customize Nessus with Over 127,000 Plugins

A bonus that comes with using Nessus is that you even get protection from scans when the devices or servers are offline. Using Nessus allows your entire business environment to be safe without sharing information with people that you do not know are safe to have in your environment. Your business could be a lot safer with regular scans from Nessus. Plus, it is always updated. There are over 123,000 plugins that it uses, which allow for both local and remote security checks by authenticated users, an interface and architecture that is simple to follow and use, and even lets tech experts create their own unique plugins. There is also extra documentation so that you can fully understand what the existing plugins are capable of. Nessus was made to be user-friendly, which is often great news for both tech-friendly and non-tech businesses alike.

How is Nessus Different Than Other Network Security Tools?

When most business owners look for network security tools, they feel overwhelmed. Just the idea of having to use a tool like this makes them nervous. However, Nessus is different. While you still may not feel comfortable reading the results on your own, it is set up to be user-friendly and approachable. The results you get when you run a scan are very fast, and it gives you an overview of how secure your network is with just the click of your mouse.

Nessus Pinpoints Vulnerabilities

Most hackers determine where to strike by first running a scan that lets them see where a businesses’ system is vulnerable. This is called a penetration test. This test will look through your entire business along with all associated devices, and pinpoints where the hacker could most easily get in and exploit information from your business. They are on the lookout for ports that are open, areas that do not require passwords, software titles that are out of date, and similar holes. Then, they set up their mission of exploiting those vulnerabilities until they can get in and take whatever information is in front of them.

Instead of allowing these holes to exist, we use Nessus to go over your entire network. It includes everything connected to your network and allows you to see where there may be existing gaps in your security measures. You have the main software, plus all of its associated tools to help you keep your network safe. There are specific steps that go into getting the most out of Nessus.

Nessus Scan Types

Once the installation and plugin setup are complete, you should run your first vulnerability scan. Since this software is designed to scan for several issues, you have many different options. However, the first scan we will run will be a network scan to get an idea if there are any issues that you need to be aware of right off the bat. Expect this first scan to take a little longer than most subsequent scans, as it will look over every bit of information and every device that is connected toy our network.

There are many different scans that Nessus is capable of running that can help your business. We will determine which scans are best based on the type of business you have and any issues with compliance you may have already in your business. Here are some of the most common scans we typically use when we use Nessus.

  • Host Discovery Scans: This is when we scan to see if there are any open ports or live hosts on your network.
  • Basic Network Scans: This is when you run a scan to simply tell you if anything is obviously vulnerable about your system where someone may come in and exploit the issue.
  • Malware Scans: This is a scan that looks over Unix and Windows systems in search of any type of malware.
  • PCI Compliance Quarterly Scans: This is when a scan is performed quarterly on external access to your system to help maintain PCI compliance.
  • OVAL and SCAP Audits: This is when we use Nessus to audit your system using OVAL and/or SCAP definitions.

Getting Information from Your Nessus Results

After the scan, you will see a lot of colorful results. Each device on your network will have results, and each color you see represents the threats where a potential vulnerability exists. The colors range from low danger to critical risk of vulnerability. You should see all devices on your local network, including your servers, firewalls, network equipment, printers (if network-enabled), your laptops or PCs, and workstations around your business. Each graph you see has more information about the vulnerability of the specific devices, so you not only get information that shows that the device is vulnerable, but also how.

Vulnerabilities Assessment

You will see each vulnerability shown as a plugin, because that is how this software discovers holes of vulnerabilities. If you click on a plugin, it will provide you with more information about how this problem creates vulnerability. You can also find additional information on how to fix this type of issue. Thankfully, if you do not want to take the time to figure out how to fix each vulnerability you have, you can turn to this Los Angeles cybersecurity firm and we will help you.

You also have the option of understanding how this creates a problem for your business. One of the major benefits of using Nessus is that it helps to provide you with a lot of information. This means you can look at each vulnerability, and it will explain to you how a potential hacker would be able to exploit the problem. It also tells you the processes a hacker would use. If you had old firmware on an outdated device, you may see an explanation such as, a hacker could create fake access points using this vulnerability. That lets you see how sneaky a hacker could be and shows you that even something you likely forgot about (the old firmware since the device was outdated) is a possible problem.

Taking Action Based on Your Nessus Results

You will be given a lot of information about your business when you look through the Nessus results. However, you may not understand what to do to protect yourself from those vulnerabilities. Thankfully, that is part of what makes us such an effective Los Angeles cybersecurity firm. We can go through and explain your results, plus offer you suggestions on what can be done to help secure your company. You never want to leave yourself open to an attack. Prior to your Nessus scans, you may not have had any type of an idea you were even vulnerable. However, now that you know, you need to be able to take steps to protect yourself, your business, and your customers.

If you were to neglect your Nessus Scan results, it could leave your business and customers open to identity theft or personal attacks. This is not a solution you want, and it could lead to the ruin of your company. Bad reputations for safety concerns travel quickly. Instead, allow the experienced professionals here at Be Structured provide you with solutions that can close those vulnerable holes and give you the security you need and deserve.

After the full scan, we will look at the remediations tab. This is where we will see the largest problems are. Going back to the example of outdated firmware, we would see that listed here, along with the other issues that your network faces. While we may go through and update your devices often, some are bound to slip through the cracks that will wind up on this list. We need to determine if we should close the vulnerability or to remove the device from your network. Both are viable options, depending on the size of your network. Occasionally the risks are very low too and remediation is deemed not necessary.

Do You Know What is On Your Network?

Hackers are always on the lookout for any way into a busy network. Those networks that are overloaded and busy, often have more gaps in them than tiny networks, since those are easier to maintain. It is vital that you know what is on your network. This scan by Nessus may give you a lot more insight as to what is going on in your network than you expected. We will take the time to go over the results with you fully and remove whatever vulnerabilities we determine to be necessary. If you are not sure how to make a problem area within your network safe, then ask us. We understand how to configure servers, set up networks, authenticate users, install security software, and so much more. If you have an open gap in your network, we can fix it.

Vulnerabilities Are Scary and Should Not Be Ignored

You will see a lot of information when looking over a Nessus report. While it can be a bit scary to see that you really are vulnerable to an outside attack, it is also important that you know there are solutions to fix it. Sitting back and worrying about the holes in your network is not going to help it fix itself. You need the right tools to make sure each hole is closed up the right way. Seeing these openings is only the start of what needs to be done.

You also need to understand that these vulnerabilities are sometimes somewhat limited. For example, if you are talking about an opening with an outdated device that has not been used in years, the information the hacker could have access to is going to be limited as well. However, if you are not sure where a device is or who may be using it, the limitations are unknown at that point. That is part of what makes taking care of any vulnerabilities you may have so important. You never know what type of limitations a device may have unless someone tries to access it. At that point, it is simply not worth the risk.

Protect Your Business With Nessus Scanning

Are You At Risk For A Cyber Attack?Ninety-five percent of network security breaches are due to human error. Empowering your team with the knowledge and skills to identify cybersecurity threats is essential to keeping your network protected. After all, a team of cybersecurity experts can only protect your network so much; at a certain point, it’s up to your everyday users to sidestep threats before they cripple your network. That’s where cybersecurity awareness training, such as phishing email training from Be Structured, comes into play.

The first step to cultivating a culture of cybersecurity awareness is simply to inform your team about the reality of cyber threats. As new threats emerge, it’s critical to provide ongoing training that helps employees spot threats and avoid them. Phishing email training is one of the most straightforward ways of accomplishing this goal. When you partner with Be Structured, it’s easy to ensure your team stays one step ahead of cybercriminals by automating ongoing phishing attacks.

Phishing email training automatically sends team members simulated phishing attacks on an ongoing basis. Your team will be able to report the email as phishing or, if caught unaware, click on one of the links. If they report the email, they’re congratulated and notified that it was a simulated attack. If, however, they fall victim to the simulated attack, they’re required to complete an additional security awareness training course online to bolster their awareness.
