Everything You Need to Know about the Vulnerability Assessment Process

A vulnerability assessment is an appraisal of a system’s susceptibility to attack. During this kind of analysis, as many flaws in the system’s security as possible are identified and graded according to their level of risk. This strategy may include both automated and human operations, each with a different degree of stringency and an emphasis on total coverage. Vulnerability assessments may target various layers of technology when employing a risk-based technique, especially when detecting the log4shell vulnerability.

Vulnerability Assessment Types

Several types of vulnerability assessments use a distinct collection of diagnostic tools to evaluate a system’s or network’s issues. Automated systems may need to do several distinct assessments to identify all of their potential flaws.

Host Assessments

The major emphasis of a host review is on the most critical servers, workstations, and other network hosts. A network assessment can tell you about ports and services, but a host assessment can tell you about the host’s patching history and how it is set up.

Network Assessments

It is possible to discover potential network vulnerabilities by examining the network. These procedures may be performed on both wired and wireless networks. These assessments help to avoid security threats that target both public and private networks, as well as information accessible through the network.

Wireless Assessments

A wireless assessment will primarily focus on an enterprise’s Wi-Fi network. Wireless networks that are not adequately protected, particularly those with rogue access points, may expose an organization’s infrastructure to attack. These assessments also validate that an organization’s network is secure and appropriately configured.

Database Assessments

Database assessments include analyzing an organization’s database for problems. Malicious attacks, such as SQL injections, target databases with wrong configurations, rogue databases, and inadequate development testing (DevTest). These assessments can help businesses determine if sections of a particular infrastructure include personal information that must be classified.

Application Assessments

Online programs, websites, and source code are examined during an application evaluation to detect incorrect software downloads, bad installations, and other security vulnerabilities. These are often automated scans of the front-end code and infrastructure.

Common Cybersecurity Vulnerabilities

As more businesses add more and more digitalization and automation to their operations, the need for proactive risk and vulnerability management will only grow. A single security compromise might have far-reaching repercussions beyond unplanned downtime. Moreover, security breaches may cost the organization thousands of dollars. The following are four common types of vulnerabilities that every business must know:

Zero-Day Exploits

Since hackers often exploit software defects before they are made public, these vulnerabilities pose a significant threat to organizations’ networks. End users discovering a security flaw in commercial software will often alert the program’s designer or post information about the problem online. Hackers may exploit software defects even if the companies that provide the program are doing everything necessary to fix the issues as soon as feasible.

Authentication Flaws

Authentication methods that check users help companies protect their sensitive data and important applications. This strategy helps to ensure that unauthorized individuals, whether within or outside the organization, are unable to access critical data repositories or interact with network settings. If a well-planned and executed phishing scam or brute-force attack is utilized, hackers may get access to computer systems and data repositories that are not protected by two-factor or biometric authentication.

Untrained Personnel

Unfortunately, when it comes to the security of computer systems, private networks, and mission-critical applications, end-users are often the weakest link in the chain. When an employee is unfamiliar with cybersecurity best practices, they may unwittingly download dangerous malware by clicking on an infected link or downloading a malicious email attachment.

Network Vulnerabilities

Many business owners believe that their networks are risk-free and safe, yet their systems are significantly more susceptible than they realize. Spoofing attacks may cause users to provide information they do not wish to disclose to an attacker. This vulnerability affects a broad range of services and protocols. IT departments should conduct frequent network audits to find any new security flaws that may have been created.

How to Do a Vulnerability Assessment

If you have the right tools, you can do a vulnerability assessment by using the following steps in the order given:

Asset Identification

To begin, you must decide what you want to scan, which is not always as simple as it seems. One of the most common barriers to cyber security for a company is a lack of insight into its digital infrastructure and the connected devices it includes.


When you’ve taken inventory of everything you possess, the next issue is whether you have the financial resources to do a risk assessment on everything. In an ideal world, a vulnerability assessment should be performed consistently across all of your systems. Prioritization, on the other hand, may be useful in cases when budgets cannot cover every asset owned by the organization since many suppliers charge on a per-asset basis.

Vulnerability Scanning

Vulnerability scanners are programs that look for known issues in a system’s security and then advise on how to address such issues. Because of the regularity with which these problems are publicly disclosed, a wealth of information about vulnerable software is easily available. Vulnerability scanners analyze this information and use the findings to discover vulnerable devices and software inside an organization’s infrastructure.

Result Analysis & Remediation

After the vulnerability scan is finished, the scanner generates an assessment report. While reviewing this report and making remedial strategies based on it, keep the following in mind:


A vulnerability scanner should put a possible issue into one of several categories based on how bad it is. It is critical to prioritize the most significant vulnerabilities first while planning for fixing, but it is equally critical not to overlook the other vulnerabilities forever. It is fairly uncommon for hackers to combine many moderate-severity vulnerabilities to create an attack. A trustworthy vulnerability scanner will estimate when each issue should be resolved and offer a deadline for doing so.

Vulnerability Exposure

It is important to remember that not all vulnerabilities are found in systems that are open to the public. A person who is randomly searching the internet is more likely to abuse a device that can connect to the internet. As such, fixing vulnerabilities in these systems should take precedence. After that, you should make it a high priority to fix any staff PCs running vulnerable software. Moreover, systems that contain extremely sensitive data or have the potential to harm your firm may need to be prioritized above all others.

Today, when almost all businesses are moving their most important services online, it’s important to have a good cybersecurity plan in place. As part of this plan, your organization should undertake vulnerability assessments regularly. This ensures that any external threats are detected and addressed as soon as feasible, rather than waiting until a later period.
