Top 10 Tools to Scan Linux Servers for Vulnerability and Malware

Scan Linux Servers

Are you searching for a tool which can recognize, characterized, categorized to Scan Linux Servers etc. the security holes, then this article can provide you a solution where you can get the details about the most comprehensive tools .

Vulnerability is the detected part of any vulnerability assessment, which is the point that needs to be disclosed. There are few disclosures that executed by some individual teams like the organization have to get discovered by Computer Emergency Readiness Team (CERT) or vulnerability.

These vulnerabilities are only the reason for malicious activities like cracking the system, website, and LANs.

Now you might be wondering what the vulnerability Scanner is? It is an automated security auditing that plays a vital part in your IT security by scanning your network.

It also does the scanning of your website for several security risks. Scanners are also generated the prioritize the list where you must patch, and they also must describe the vulnerability.

They also need to take a step to remediate them. Here you will get the automated patching process by Scan Linux Servers with the most important tools.

Linux-based systems are considered to be impenetrable, and they also know to take the risk seriously. Many harmful programs like rootkits, ransomware, viruses, etc. can cause the problem for Linux servers.

The operating system must be fully secure because of the server. Many large brands and organisation have taken the responsibility to develop some tools so that it does not detect malware and can make them capable to take preventive actions. There are many tools available at an affordable price that can help with this process.

Top 10 Tools to Scan Linux Servers

  • Lynis
  • Chkrootkit
  • Rkhunter
  • ClamAV
  • LMD
  • Radare2
  • OpenVAS
  • REMnux
  • Tiger
  • Maltrail


This is one of the renowned tools to Scan Linux Servers which is a preferable option for Linux. It works based on Unix and macOS. This is an open-source software which is getting used since 2007 under the GPL license.


This can detect the security hole which configures the flow. Sometimes it goes beyond that, so just exposing the vulnerability is not the matter. You need to take corrective action and get a detailed auditing report.

It must run the host system. Installation is not important for the Lynis; user can extract it and run this. You will also get this from the Git clone to gets access to complete documentation and code.

Lynis has two types of service, and it works depends on the individuals and enterprise but is expected to be an outstanding performance.


This is the another best tool to Scan Linux servers that is the existence of rootkit and this is one type of malicious software that gives unauthorized user access. If you are working on a Linux-based server, then rootkit can cause the problem.


To detect the rootkit, the best program is a Unix-based program. It also uses ‘strings’ and ‘grep’ so that it can see the issues.

You can also use this as an alternative directory from the rescue disc, or you can verify it as a compromised system.

There are different components that delete the entries and make this a ‘last log’ file. You need to find the sniffer record so that it can do the checking of hidden entries.

To do the proper use, you must have the latest version of the server so that you can extract the file, and after that, you can compile them so that you can ready to start.



Rkhunter develops in 2003. This is suitable for the POSIX system, and it also helps to detect the rootkit and other vulnerabilities.

This Rkhunter makes sure that it goes through all the files separately and does the default directories, misconfiguration, kernel modules, etc.

Due to this application, everything must go with a routine check-up, and compare to others, it is safe and maintain the proper record.

It also conducts a suspicious program which is written on bash, and this runs in everything but does not run in Linux machine and other versions of Unix.


  1. This is an open-source to Scan Linux Servers that helps detect the trojans, virus, and any other malware. This application is fully free so only many people scan their emails, personal information, other types of malicious files, etc.

This tool got developed not being many days, especially for Unix. It also has the third-party version, which can be used in BSD, AIX, OSF, OpenVMS, macOS, etc.

It provides automatic and regular updates to all the database, and detect the recent threats.

It also allows command-line scanning, which has a multi-threaded option which improve the scan speed.

It also helps you to detect a different kind of files includes Zip, Gzip, RAR, Tar, CHM, SIS format, and much more.


  1. Linux Malware Detect is one of the renowned antiviruses for Linux systems. This is perfect for identifying the threats and found in the hosted environment. Unlike other, it can detect malware and rootkits.
  2. It also uses as a signature databae;s if it finds out any malicious running code, then it quickly terminates that.

It does not have an exact limit, and its working with its own signature database. It includes leverage Team Cymru’s and ClamAV, and it helps to find more viruses.

To make populate the database, LMD captures the threat and gives the network edge intrusion, which can detect the system.

LMD also gets used through “maldet”, which is the standard line and this is specially made for the Linux platform, which can easily search for the Linux servers.


  1. It is a framework to analyze the binaries, and it does the reverse-engineering, which can do the excellent detection ability. It detects the malformed binaries and gives the user access to tools to manage and neutralize the potential threats.

Many software security researchers prefer to use this tool to get excellent data presentation ability.

One more outstanding features it has where the user not get forced to use the command line and do the task like dynamic analysis, software exploitation, and much more. It’s recommended that users can do research any binary data.


This is also called Open Vulnerability Assessment System to Scan Linux Servers, which is hosted by the vulnerabilities and helps them to manage. It is correctly designed so that it can fit all business types. It also helps to detect the security issue which has hidden with their infrastructure.


Usually, this product is also well-known as GNessUs, and this is the current owner, and now it got changed to OpenVAS. This is the  4.0 version which provides continuous updating.

This is one of the best networks which provides Network Vulnerability Testing (NVT). Most of the security experts prefer to use this because it can scan fast compare to others.

It also gives excellent configurability, which gets used by the self-contained virtual machine to do safe malware research.



This is a reverse-engineering method that can analyze the malware and can detect many browser-based issues.

It has hidden JavaScript, which has obfuscated code and flash applets.

It is capable of scanning PDF files, which perform memory forensics. It also helps to detect the malicious program where it can detect the virus quickly.

This is very much effective because of its decoding and reverse-engineering capabilities, which determine the suspicious program, and it is very much an undetectable innovative malicious program. This application gets used for both Windows and Linux.



This is one of the best applications introduced by 1992 and A&M University started working on it.

This is a very popular program, especially for the Unix-like platform. This is the security audit tool, which also does the intrusion detection system.

This is free to use under a GPL license. This depends on the POSIX tool where it can create the perfect framework to increase security.

This tool is written in shell language, and this makes this tool more effective. It is best to check the system status and other configurations.

Tiger also can be used for multipurpose and even for those who use POSIX tools.


It is one of the best traffic detection systems capable of keeping the server traffic clean. This works best for avoiding malicious threats. This tool performs all tasks where traffic sources backlisted the sites and publish things online.


If you check the blacklisted site, then you might have used the heuristic mechanism to detect different threats. Though it is optional, it can manage the server that has already been attacked.

This is a sensor capable of detecting traffic where the server sends the information to the Maltrail server.

This is the detection system, that verifies the traffic quality and enhanced the data between source and server.

How to Choose the Best Tool Scan Linux Servers?

This is very tough because the abovementioned work very well which is very good for the Linux environment. We are pretty sure that many people are using it. One most important thing is each tool is dependents on other tools. You need to select based on your requirement so that it can have the best vulnerability.
