Vulnerability scanning or vulnerability assessment is a systematic process of finding security loopholes in any system addressing the potential vulnerabilities. The purpose of vulnerability assessments is to prevent the possibility of unauthorized access to systems. Vulnerability testing preserves the confidentiality, integrity, and availability of the system. The system refers to any computers, networks, network devices, software, web application, cloud computing, etc. Vulnerability scanners have their ways of doing jobs. We can classify the vulnerability scanners into four types based on how they operate. Used to find vulnerabilities within cloud-based systems such as web applications, WordPress, and Joomla. Used to find vulnerabilities on a single host or system such as an individual computer or a network device like a switch or core-router. Used to find vulnerabilities in an internal network by scanning for open ports. Services running on open ports determined whether vulnerabilities exist or not with the help of the tool. Used to find vulnerabilities in database management systems. Databases are the backbone of any system storing sensitive information. Vulnerability scanning is performed on database systems to prevent attacks like SQL Injection. Vulnerability scanning tools allow for the detection of vulnerabilities in applications using many ways. Code analysis vulnerability tools analyze coding bugs. Audit vulnerability tools can find well-known rootkits, backdoor, and trojans. There are many vulnerability scanners available in the market. They can be free, paid, or open-source. Most of the free and open-source tools are available on GitHub. Deciding which tool to use depends on a few factors such as vulnerability type, budget, frequency of how often the tool is updated, etc. Nikto2 is an open-source vulnerability scanning software that focuses on web application security.
