Network Vulnerability Scanning
Network vulnerability scanning is a technique that identifies vulnerabilities in the networks that connect computers and devices. It detects vulnerabilities on different types of devices, including routers, switches, firewalls, and clusters. Network vulnerabilities can also be found on host computers. Host-based scans look at a host’s configuration, memory settings, and user directories. Both types of scans can identify potential threats to networks and data.
The type of network vulnerability scans that’s used depends on the industry and company guidelines. For instance, a healthcare company might focus on HIPAA compliance, which means avoiding storing personal health identifiers on electronic media. Other industries may scan web applications to find common configuration issues, such as missing SSL certificates and security headers.
Network vulnerability scanning is an essential part of network security. Without it, networks can fall prey to cyberattacks. These attacks can cause major operational disruptions, prevent customers from communicating with you, and result in data breaches. These types of breaches can have a negative impact on a business’s reputation and expose it to large fines. To protect your network, you must scan for vulnerabilities and make sure they’re repaired as soon as possible.
Network Vulnerability Scanning Examples
Once you’ve run a vulnerability scan, you need to document it to ensure it’s thorough and effective. There are two main types of vulnerability scans: authenticated and non-authenticated scans. A non-authenticated scan involves an IT specialist logging in as an intruder to see if there are any vulnerabilities. An authentic scan, on the other hand, requires the IT specialist to log in as a trusted user and can uncover security loopholes that only authorized users can exploit.
When done properly, vulnerability scanning can serve as an early warning system for intrusions. In addition, it can identify vulnerable areas and create extra security measures to address them. It can also help you to formulate a backup plan in case of a breach. However, vulnerability scanning is a time-consuming and labor-intensive process.
A network vulnerability scanner needs to be comprehensive. It should cover all major operating systems and software flavors. The scan should also check esoteric systems, such as SCADA controls. A network vulnerability scanner should prioritize vulnerabilities based on their severity, impact, and likelihood of an attack. Once the scan results are in, IT administrators can prioritize the remediation efforts based on the severity of the threats and prioritize the best ones for immediate action.
When scanning networks, it’s important to understand the different types of vulnerability scans available. The first method identifies vulnerable services by scanning their ports. The other method relies on database scanning. It enumerates vulnerable systems and provides their respective versions. Both methods have their advantages and disadvantages.
The process of network vulnerability scanning can be complex, so it’s best to follow a structured, methodical approach to ensure that the security of your network is robust. The results will help you understand where weaknesses are and how to improve them.
