This article is an introduction to vulnerability assessments, one of the most effective and affordable techniques for discovering system flaws. Read on to learn how a vulnerability assessment helps detect system faults, evaluate risks, and improve overall cybersecurity.
Introduction to Vulnerability Assessment
A company wishing to organize a vulnerability test has two options: have the in-house staff run the test or hire a third-party to evaluate the system. While going with the in-house team is the cheaper choice, the best results come from testers unfamiliar with the subject system and its protocols.
Network assessment scans identify possible threats to network security. Testers inspect hubs, switches, routers, clusters, and servers to ensure network-accessible resources are safe from malicious actors.
Both vulnerability analysis and penetration testing detect weaknesses within an IT system and improve the overall security level. A penetration test also typically includes a vulnerability scan by default.
However, there is a difference between the two testing processes. Whereas a vulnerability scan tries to detect and mitigate system flaws, a pen test involves actual attempts to exploit weaknesses. Pen testers (or ethical hackers) actively try to break into a system by simulating a real cyberattack in a controlled setting. The goal is to prove that:
A vulnerability assessment discovers, quantifies, and prioritizes weaknesses in an IT environment. In contrast, a risk assessment evaluates the probability that certain flaws and threat actors will lead to an exposure or data loss.
A vulnerability scan is larger in scope than a risk assessment. A complete analysis not only evaluates the likelihood of a breach but also deals with potential consequences and strategies for avoiding future incidents.
A vulnerability assessment process is intended to identify threats and the risks they pose. They typically involve the use of automated testing tools, such as network security scanners, whose results are listed in a vulnerability assessment report.
Organizations of any size, or even individuals who face an increased risk of cyber attacks, can benefit from some form of vulnerability assessment, but large enterprises and other types of organizations that are subject to ongoing attacks will benefit most from vulnerability analysis.
Because security vulnerabilities can enable hackers to access IT systems and applications, it is essential for enterprises to identify and remediate weaknesses before they can be exploited. A comprehensive vulnerability assessment, along with a management program, can help companies improve the security of their systems.
A vulnerability assessment provides an organization with details on any security weaknesses in its environment. It also provides direction on how to assess the risks associated with those weaknesses. This process offers the organization a better understanding of its assets, security flaws and overall risk, reducing the likelihood that a cybercriminal will breach its systems and catch the business off guard.
Vulnerability assessments discover different types of system or network vulnerabilities. This means the assessment process includes using a variety of tools, scanners and methodologies to identify vulnerabilities, threats and risks.
A vulnerability assessment often includes a penetration testing component to identify vulnerabilities in an organization's personnel, procedures or processes. These vulnerabilities might not normally be detectable with network or system scans. The process is sometimes referred to as vulnerability assessment/penetration testing, or VAPT.
However, penetration testing is not sufficient as a complete vulnerability assessment and is, in fact, a separate process. A vulnerability assessment aims to uncover vulnerabilities in a network and recommend the appropriate mitigation or remediation to reduce or remove the risks.
A vulnerability assessment uses automated network security scanning tools. The results are listed in the vulnerability assessment report, which focuses on providing enterprises with a list of vulnerabilities that need to be fixed. However, it does so without evaluating specific attack goals or scenarios.
Organizations should employ vulnerability testing on a regular basis to ensure the security of their networks, particularly when changes are made. For example, testing should be done when services are added, new equipment is installed or ports are opened.
In contrast, penetration testing involves identifying vulnerabilities in a network, and it attempts to exploit them to attack the system. Although sometimes carried out in concert with vulnerability assessments, the primary aim of penetration testing is to check whether a vulnerability really exists. In addition, penetration testing tries to prove that exploiting a vulnerability can damage the application or network.
While a vulnerability assessment is usually automated to cover a wide variety of unpatched vulnerabilities, penetration testing generally combines automated and manual techniques to help testers delve further into the vulnerabilities and exploit them to gain access to the network in a controlled environment.
A vulnerability assessment is a systematic review of security weaknesses in an information system. It evaluates if the system is susceptible to any known vulnerabilities, assigns severity levels to those vulnerabilities, and recommends remediation or mitigation, if and whenever needed.
This course introduces the preparatory skills needed to learn penetration testing and vulnerability assessment, and familiarizes Information Technology support personnel and managers with the tactics, techniques and procedures (TTPs) that are used by attackers and penetration testers. Participants will have an increased knowledge and understanding about the tools used in a cyber-attack and in turn be better able to prepare defenses. The course focuses on the basic skills and knowledge needed to conduct and plan vulnerability assessments and penetration tests as well as show how to legally and ethically conduct tests and assessments. Participants will be introduced to Open Source tools such as Metasploit and Nmap, as well as methodologies for researching vulnerabilities. This course is designed based on research and federal agency reports.
Vulnerability Assessment and Penetration Testing (VAPT) are two types of vulnerability testing. The tests have different strengths and are often combined to achieve a more complete vulnerability analysis. In short, Penetration Testing and Vulnerability Assessments perform two different tasks, usually with different results, within the same area of focus.
Vulnerability assessment tools discover which vulnerabilities are present, but they do not differentiate between flaws that can be exploited to cause damage and those that cannot. Vulnerability scanners alert companies to the preexisting flaws in their code and where they are located. Penetration tests attempt to exploit the vulnerabilities in a system to determine whether unauthorized access or other malicious activity is possible and identify which flaws pose a threat to the application. Penetration tests find exploitable flaws and measure the severity of each. A penetration test is meant to show how damaging a flaw could be in a real attack rather than find every flaw in a system. Together, penetration testing and vulnerability assessment tools provide a detailed picture of the flaws that exist in an application and the risks associated with those flaws.
Veracode has developed an automated, on-demand, application security testing solution. With Veracode, companies no longer need to buy expensive vulnerability assessment software, train developers and QA personnel on how to use it, or spend time and money to constantly update it. The Veracode platform is dynamically updated and upgraded, meaning users reap the latest benefits every time they log in.

A vulnerability assessment is the process of identifying, quantifying, and prioritizing (or ranking) the vulnerabilities in a system. Examples of systems for which vulnerability assessments are performed include, but are not limited to, information technology systems, energy supply systems, water supply systems, transportation systems, and communication systems. Such assessments may be conducted on behalf of a range of different organizations, from small businesses up to large regional infrastructures. Vulnerability from the perspective of disaster management means assessing the threats from potential hazards to the population and to infrastructure.It may be conducted in the political, social, economic or environmental fields.
"Classical risk analysis is principally concerned with investigating the risks surrounding a plant (or some other object), its design and operations. Such analysis tends to focus on causes and the direct consequences for the studied object. Vulnerability analysis, on the other hand, focuses both on consequences for the object itself and on primary and secondary consequences for the surrounding environment. It also concerns itself with the possibilities of reducing such consequences and of improving the capacity to manage future incidents." (Lövkvist-Andersen, et al., 2004) In general, a vulnerability analysis serves to "categorize key assets and drive the risk management process." (United States Department of Energy, 2002)1
In the United States, guides providing valuable considerations and templates for completing a vulnerability assessment are available from numerous agencies including the Department of Energy, the Environmental Protection Agency, and the United States Department of Transportation, just to name a few. 2ff7e9595c
