Vulnerability Assessment
Vulnerability assessment is a method used to detect vulnerabilities and threats on a target network by utilizing automatic scanning tools and manual support. Once the tool categorizes these vulnerabilities, security professionals prioritize them to decide which vulnerability to address first. They may opt to reduce the risk level or eliminate the vulnerabilities. There are numerous effective tools available in the market for this purpose. By conducting a properly scoped vulnerability scan, it is possible to uncover common application weaknesses, unapplied patches, gaps in network control, and vulnerabilities in software versions. Using a vulnerability scanning tool, the security team can recommend how to precisely remediate vulnerabilities with configuration changes, patch management, or hardening security infrastructure.
Vulnerability Assessment Process
- The vulnerability scanner in our environment accomplishes automated discovery of all assets.
- The vulnerabilities in infrastructure, network, and application are detected and identified.
- The vulnerabilities are prioritized and categorized based on their level of risk.
- The security professional remedies vulnerabilities through configuration changes, patch management, or enhancing the security infrastructure.
Penetration Testing
Penetration testing is a method used to discover vulnerabilities in a specific network, and to verify the authenticity of the vulnerabilities. If a penetration tester is able to exploit a potentially vulnerable area, the vulnerability is considered genuine and is included in the report. The report may also show unexploitable theoretical vulnerabilities if no vulnerable spot is found. It is not recommended to exploit theoretical vulnerabilities as it may lead to DoS, which can threaten the network. Penetration testers may attempt to harm a client’s network by installing malicious software on their computer, taking down servers, or gaining unauthorized access to their system, which is not included in vulnerability assessments.
Penetration Testing Process
- Gathering the open-source intelligence
- Scanning and discovering
- Identify the vulnerabilities
- Attack phase
- Risk analysis
- Send report
Differences between Vulnerability Assessment and Penetration Testing
Although vulnerability scanning and penetration testing are related to each other, they serve different purposes. While vulnerability scanning identifies and reports the severity of vulnerabilities, penetration testing takes things further by actively exploiting vulnerabilities to assess the effectiveness of the security controls in place. To summarize, the distinctions between vulnerability assessment and penetration testing are as follows:
Breadth vs. Depth
The main difference between penetration testing and vulnerability assessment is the breadth and depth of vulnerability coverage.
| Vulnerability Assessment | Penetration Testing |
| The breadth-over-depth approach of vulnerability assessment aims to detect as many security weaknesses as possible to maintain the security of the network. Regular security measures should be implemented, particularly when new services are added, ports are opened, or new equipment is installed. | Penetration testing is employed by clients who claim to have robust security defenses in place but desire to test the hack-proof nature of their network. This approach focuses on depth over breadth, seeking to thoroughly examine the network’s vulnerabilities rather than simply detecting their presence. |
The Automation Degree
| Vulnerability Assessment | Penetration Testing |
| The scope of vulnerability detection is broader in vulnerability assessment, and it typically involves an automated process. | Penetration testing is a comprehensive approach to uncovering vulnerabilities, employing both manual and automated techniques. |
Choice of Professional
| Vulnerability Assessment | Penetration Testing |
| Automated testing is typically utilized in vulnerability assessments and does not demand extensive expertise, making it feasible for a company’s security department members to conduct. However, while internal security personnel may identify vulnerabilities, they may be unable to include them in a report. As a result, third-party vendors specializing in vulnerability assessments typically possess a greater wealth of information. | Penetration testing necessitates a high degree of expertise, and it is typically outsourced to a service provider specializing in the field. |
Choice of Vendors
The dissimilarities between penetration testing and vulnerability assessment indicate that both types of security testing are necessary to safeguard the security of a network and require the expertise of a skilled professional.
| Vulnerability Assessment | Penetration Testing |
| Vulnerability assessment is a vital tool for maintaining security. | Penetration testing reveals security weaknesses. |
To derive maximum benefit from penetration testing and vulnerability assessment, it is essential to engage a high-quality vendor capable of comprehending the nuances of these assessments and, more importantly, able to explain the distinctions between them to the client.
