With an increasing number of cyber related incidents in today's digital landscape, the need for effective vulnerability management and assessment has become more important than ever. From significant data breaches to more minor tech mishaps, every organisation is at risk, regardless of its size, industry, or capabilities. In order to identify the main components of vulnerability management and assessment, a robust cybersecurity strategy is a necessity.

Vulnerability management is an ongoing cybersecurity process that involves identifying, classifying, remediating, and mitigating vulnerabilities. This process can be separated into five main components: identification, analysis, evaluation, treatment, and review. It is its continuous nature that makes vulnerability management an integral part of cybersecurity efforts.

Component 1: Identification

The process starts with vulnerability identification. For this aspect, IT professionals should use automated tools and techniques to identify system vulnerabilities in their networks, servers, and applications. They should also scan and evaluate their external and internal environmments for unfamiliar or unauthorized devices, as these can serve as potential entry points for hackers.

Component 2: Analysis

After identification comes the analysis phase. It involves assessing discovered vulnerabilities in relation to the network, server, or application they reside in. The objective is to determine the effects exploitation of each vulnerability would have on the organization. Factors such as potential data loss, system downtime, and reputational damage are all considered here.

Component 3: Evaluation

Vulnerability evaluation is the next step where the severity of vulnerabilities is ranked based on criteria such as their potential impact, the resources required to exploit them, and the likelihood of exploitation. This stage is crucial for prioritising remediation efforts and allocating resources where they are most needed.

Component 4: Treatment

The focus then shifts to vulnerability treatment during which mitigation and remediation strategies are developed and implemented. Remediation can include patching, configuration changes, and system upgrades. Mitigation strategies, on the other hand, are measures implemented to lessen the risk of vulnerabilities being exploited if they cannot be immediately patched.

Component 5: Review

Finally, vulnerability review involves continuously monitoring and reassessing vulnerabilities post-remediation. It ensures that the implemented measures are effective and the previously identified vulnerabilities are indeed resolved. Furthermore, it helps identify new vulnerabilities that may have developed since the last scan.

Vulnerability Assessment

Vulnerability assessment, on the other hand, is a more focused process that entails the evaluation of IT systems for potential vulnerabilities. It is often an integral part of vulnerability management and contributes to the first three steps: identification, analysis, and evaluation. Vulnerability assessments can be carried out by employing a few different methodologies, most notably network scanning, host-based scanning, and wireless network scanning.

Network Scanning

Network scanning is used for identifying active hosts within networks and the open ports and services available in those hosts. Techniques like OS fingerprinting can also be used to determine the running software and detect known vulnerabilities pertaining to that specific software.

Host-based Scanning

Host-based scanning, alternatively, is used to examine particular devices or 'hosts' like workstations or servers. It provides a more detailed perspective of the operating system and application vulnerability details.

Wireless Network Scanning

Wireless network scanning is used for identifying and securing vulnerabilities in wireless networks. Tools are used to identify open Wi-Fi access points, to assess the security protocols employed by the wireless network, and to identify potential vulnerabilities within the wireless network infrastructure.

In conclusion, the cybersecurity realm is intricate and multifaceted, but with a profound understanding of vulnerability management and assessment, businesses can better defend themselves from potential threats. In order to safeguard from potential cyber attacks, a robust comprehension and implementation of the main components of vulnerability management and assessment is imperative. By paying heed to vulnerability identification, analysis, evaluation, treatment, and review in vulnerability management, as well as utilising network scanning, host-based scanning, and wireless network scanning in the vulnerability assessment, the security of an organization's IT infrastructure can be significantly amplified. Regular reviews and updates to vulnerability management strategies are essential to ensure ongoing protection in the ever-evolving digital landscape.
