Are you wondering what is the fastest vulnerability scan? Worry not, our experts have the answer. Read on to learn more. Our Server Management team is here to lend a hand with your queries and issues.

What is the fastest vulnerability scan?

Each system or application comes with its own set of flaws. These flaws can be manipulated to create security lapses.

In most cases, vulnerabilities are a result of weak configurations or outdated software packages. This is why it is essential to track down these flaws before the attackers get a chance to exploit them.

Fortunately, there are several vulnerability scanning tools to make this task easier., A vulnerability scanner is responsible for performing tests to ensure there are no weaknesses present.

Each scanner uses a different approach to get the job done. While some scanners scan the network for active systems and check which network ports are open, other scanners run on the system itself.

The former works well for targets to which we do not have access, whereas the latter can access more data due to better access.

Linux vulnerability scanning tools help us with:

• Vulnerability management
• Vulnerability scanning
• Vulnerability check

Is Nmap the fastest vulnerability scan?

According to our experts, Nmap is one of the fastest vulnerability scanners in the market today. It helps with network discovery as well as security scanning. Furthermore, it performs port scanning, vulnerability scanning, fingerprinting operating systems, and so on.

It offers a CLI and GUI interface, making it user-friendly as well. Nmap comes with its own scripting engine as well as .nse scripts for vulnerability scanning.

How to install Nmap?

We can easily install Nmap in Linux with these commands:

$ sudo apt-get update
$ sudo apt-get upgrade -y
$ sudo apt-get install nmap -y

Then, we can use it to scan a server for open ports as well as list the services on these ports with the following code:

$ nmap hackme.org

Additionally, we can scan for UDP ports as seen below:

$ sudo nmap -sU hackme.org

Here are some of the other options available in Nmap:

• -p- : Scan for each 65535 port
• -O : Scans for OS running
• -v : Verbose scan
• -sT : TCP connect scan
• -A : Aggressive scan
• -Pn : If the server blocks ping
• -T[1-5] : To set the scanning speed
• -sC : Scan using default scripts

Let us know in the comments if you run into any trouble while using Nmap- the fastest vulnerability scanner.
