Key notes

Open-source software is the core concept for development because it is free to modify and adapt to your needs. And nothing is more configurable thannetwork security software. Here, you will find the best open-source tools for enterprise network security.

Why would I choose open-source software?

Why would I choose open-source software?

Cybersecurity tools protect enterprises from all threats andopen-source softwareis a low-budget, flexible solution for that.

However, you will need to have a strong team with high technical expertise to configure and implement the solution.

We have chosen the tools below based on their features and readiness in terms of network security and integrations.

What are the best open-source network security tools?

Wazuh– Best network privacy security

If you’re looking for the best open-source network security tool, the answer is Wazuh.

Of course, it’s an open-source solution that ensures protection for workloads across on-premises, virtualized, and cloud-based environments.

In other words, it’s an enterprise-level tool for both Cloud and endpoint security. Its agents for Windows, Linux macOS, Solaris, AIX, and HP-UX systems are capable of detecting any anomaly or rule-based transgression.

And it does that by scanning all the network components and their logs, to provide information for the central manager that will analyze and store it.

As a change in file content, attributes and permissions are viewed as privacy threats, Wazuh constantly monitors any such modifications.

However, it doesn’t just alert you, it’s also able to block access to the affected system or execute commands to remedy the situation.

Another strong advantage for Wazuh is the list of integrations with other services and tools such as YARA, AlienVault, Amazon Macie, VirusTotal, and many more.

The solution is free so that you can implement it immediately but if you need technical assistance, you will have to pay a fee.

Let’s review some of itskey features:

AlienVault OSSIM– Great SIEM solution

The OSSIM acronym from AlienVault OSSIM stands for Open Source Security Information and Event Management.

Compared to Wazuh, which also has XDR components to fight off the attacks, this solution only has SIEM features.

That means, it can detect network events and alert you so you can make the necessary changes to resolve the possible issue.

In short, AlienVault OSSIM offers asset discovery, vulnerability assessment, intrusion detection, behavioral monitoring, and SIEM event correlation.

The software is based on the proprietary Open Threat Exchange (OTX) that involves users contributing and receiving real-time information about malicious hosts.

Here are some of itsmost important features:

OpenEDR– Ideal for endpoint malware protection

OpenEDR is a free, open-source endpoint detection and response software. It provides real-time analytic detection with Mitre ATT&CK visibility.

It basically offers event correlation and root cause analysis of malicious threat activity and behaviors to help you protect your network.

One of the best advantages of OpenEDR is that it can be deployed on any endpoint environment and has a cloud-based management console.

And if you want to build integrations for it, it’s as simple as using its GitHub source code.

Let’s review some of itskey features:

Metasploit– Great for network penetration testing

If you have a strong IT management team, Metasploit can be an excellent tool to test your network vulnerability.

The software can be used to run security assessments, anticipate attacks and improve overall cybersecurity awareness.

A great advantage is that it is very flexible. You can install it on Windows (64-bit), macOS, and Linux workstations.

Moreover, you will find ready-to-use installers for fast implementation. And then, Metasploit can automate almost all the phases of a penetration test, starting with exploit tactics and ending by collecting evidence.

Here are some of itsbest features:

⇒Get Metaexploit

Nmap– Good for network scanning

Besides appearing in Matrix Reloaded and Ocean’s 8 as a hacking tool, Nmap is actually a network mapping and visualization tool.

Network administrators can use it also for network inventory, managing service upgrade schedules, and monitoring host or service uptime.

Nmap uses raw IP packets to identify which hosts are available on the network, what services are offering, what OSes they are running, and a lot more.

The tools can scan large networks very fast, and runs on all major computer operating systems. You will find official binary packages for Linux, Windows, and Mac OS X.

It comes as a command line terminal but you may also install an advanced GUI and results viewer called Zenmap.

There are also other integrations available such as Ncat (a flexible data transfer, redirection, and debugging tool), Ndiff (for comparing scan results), and Nping (a packet generation and response analysis tool.
