What are network security tools?

Learn how network security tools have evolved to detect vulnerabilities and keep your data safe.

Network security can seem like a daunting task with all of the cyber threats looming on the net. However, with the evolution of hacking has come an evolution of information security tools and techniques. Security companies are working around the clock to keep up with the latest hacking techniques. Network security tools have been forced to evolve so that people, and businesses, can keep their data safe. 

But what are network security tools? What purpose are they used for? Put simply, network security tools are things like firewalls, network-based antivirus programs, and intrusion detection systems. Security companies also offer advanced access controls and application security to try to limit unknown entities from finding weak points to access your network from. These tools work to detect potential vulnerabilities and active threats, respond to them efficiently, and protect your system from other threats down the road. 

Threats to your network security can put client data at risk, but they can also threaten the ability to use the network at all. These types of attacks, commonly known as denial of service (DoS) attacks, can shut down services and threaten the entire business for up to 24 hours. That is a lot of time for hackers to take advantage of, and a lot of time for your business to be at a standstill. 

Finding an effective network security monitoring tool doesn’t have to be a difficult task. With a little preparation and some detailed knowledge, you can narrow down your best options from any security tools list and protect your network as soon as possible. This article will give you the information you need to understand what your network needs and how to secure every piece of sensitive information on your network.

Secure for the known, insure for the unknown

Your destination may be achieving compliance in industry certifications such as SOC2 or ISO27001, but it doesn’t stop there. With Trava, our modern tools can help you bridge the gap between where you are and where you want to be by giving you the control to assess your risk, repair the most vulnerable areas, and transfer risk through insurance.

Cybersecurity Tools

Now that you have an understanding of what network security is, we can go into more detail on different types of cybersecurity tools and their benefits. Security monitoring tools and techniques are the best defense against cybercrime groups that are highly skilled and often highly paid. This is why it’s important to know who is developing the network security tools you use and how much experience they have and their reputation in the industry.

A quick web search on the subject will give you more than a few cybersecurity tools PDF, but those can require a lot of reading to get to what you really need. For a quick reference, here is a security monitoring tools list that can point you in the direction of some reputable tools.

These are some of the most popular security tools available today. Many of these offer a free trial as well. If your organization needs fully free and customizable network security monitoring tools, open-source options are available, including Argus that was listed above. No matter what you’re in the market for, a Trava vulnerability assessment is a perfect start to identifying what tools can best protect your network.

Software Security Tools

Software security tools (also referred to as application security tools) are examples of security tools that specifically protect software applications from external threats. No matter what types of network security tools and techniques you use to protect your overall network, the applications running on it can provide hackers with all they need to slip past those defenses. 

Any good network security tools list will offer recommendations for effective software security tools. You will likely similar examples of security tools like these popular options:

Many of these names appear on most cybersecurity tools list you search for online. Again, this is because hackers aren’t working alone anymore. They are organized, funded, and efficient. Using reputable companies and their tools is usually more advisable because they have the budget and the manpower to keep up with hacking trends. 

Software applications allow companies to complete and collaborate on projects across their entire network, so it is important that they are just as secure as the rest of your system. These days almost all software gets updated regularly, which can open the door to criminals on the web. The yearly number of cyber breaches through web applications is on the rise, so your business can’t afford to go much longer without a reliable software security tool.

Network Security Applications

We have used many names to describe these network and security tools and techniques discussed in this article so far.  They fall under many categories, but in the end they can all be defined as network security applications. Googling “network security tools PDF” will probably pull up files that list some methods which are used for network security and can provide helpful information and methods that will help you along in the process. But what about other helpful tools that basic web searches might not provide readily?

Resources like free cyber attack simulation tools might be a bit more obscure and require some insight to go and find. Infection Monkey and NeSSi2 are just a couple example of free network security tools that run simulations based off of current cyber attack trends. This allows security teams to get an in-depth report on what type of attacks their network is most vulnerable to and how to fix that. 

There are multiple network security applications that can provide both protection and insight into weaknesses. Doing detailed, specific research to narrow down your most effective options in the sea of network security applications that exist in 2022 is the key to protecting your network against the ever-growing methods of cyber crime.

Data Security Tools

When you hear “cybersecurity,” you likely think of protecting your data first. Data security tools are types of security tools that specifically work to make sensitive data more secure. Data encryption, password protection, data backup, and identity and access management are just some of the types of security techniques that can help protect your data.

Cybersecurity tools and techniques that deal with data are accessible and often offer free trials for their services. Cybersecurity tools PDF files can be found online and offer insight on many data security tools as well as all other types of cybersecurity tools. Data security management is also often built in to other security management tools as data is usually cited as one of the main aspects of business that management teams want to want to protect the most.

Network security tools are intrinsically tied to data protection because many of those tools utilize tactics to protect data in one way or another. However, implementing a dedicated data security tool will ensure that you know exactly how your data is being protected and you can rest easy knowing that sensitive information will stay behind those defenses.

Open Source Network Security Tools

Open-source cybersecurity tools have been a staple of cybersecurity for a long time. They are essentially free security tools that often allow for their code to be modified to fit specific needs, but are functional and effective without any modifications. Open-source endpoint protection (protecting access points like laptops, desktops and mobile devices) and open-source network security monitoring (collecting data from systems for analysis and threat detection) are two popular forms of the best open-source security tools available. 

To get right to the point, Wireshark, Snort, and ELK are commonly regarded as the best free security tools available. They are powerful, provide detailed reports, and offer industry specific modifications that don’t require an entire IT department to implement. They appear at the top of many lists on open-source security tools. 2021 saw Wireshark at number 2 for many lists and the top of those lists in 2022.

Whether you’re using free tools or paying for them, getting the most out of the security you employ starts with understanding what type of threats you are at risk of. Trava can run a number of assessments to determine your network security and help you take the actions necessary to protect your business and your clients.
