Many organisations simplify the task by performing monthly scans to keep on top of any emerging vulnerabilities. Remediation is usually the best approach. You can learn more about your testing requirements by downloading Assured Security — Getting cyber secure with penetration testing. This free green paper explains in more detail how penetration testing works, the vulnerabilities you should be concerned about and the different types of penetration test you can use to detect them.
The tester — known as an ethical hacker — works on behalf of an organisation and looks for vulnerabilities in its systems.
In that regard, their actual work is much the same way as a criminal hacker. Indeed, unlike vulnerability scans, penetration tests are designed to identify not only weaknesses but also exploit them.
Doing this demonstrates to an organisation exactly how a cyber criminal would infiltrate its systems and what information they could access. On the other hand, vulnerability scanning is the act of identifying potential vulnerabilities in network devices such as firewalls, routers, switches, servers and applications.
It is automated and focuses on finding potential and known vulnerabilities on the network or an application level. It does not exploit the vulnerabilities. Vulnerability scanners only identify potential vulnerabilities; they do not exploit the vulnerabilities.
Hence, they are not built to find zero-day exploits. The scope of vulnerability scanning is business-wide, requiring automated tools to manage a high number of assets. It is wider in scope than penetration testing.
Products specific knowledge is needed to effectively use the vulnerability scans product. It is usually run by administrators or security personnel with good networking knowledge. Blog Vulnerability Scanning vs. Penetration Testing. Business Imperatives Vulnerability Scanning vs. Penetration Testing Vulnerability scans and penetration tests are very different from each other, but both serve important functions for protecting a networked environment Wednesday, December 20, By: Patrick Barnett - IT Security When people misunderstand the differences between penetration testing and vulnerability scans, they are often missing a vital component in their overall network security profile and both are crucial for cybercrime prevention.
Table 1 lists the differences between vulnerability scans and penetration tests. Vulnerability scan Penetration test Frequency At least quarterly, especially after new equipment is loaded or the network undergoes significant changes Once or twice a year, as well as anytime the Internet-facing equipment undergoes significant changes Reports Provide a comprehensive baseline of what vulnerabilities exist and what changed since the last report Concisely identify what data was compromised Focus Lists known software vulnerabilities that could be exploited Discovers unknown and exploitable weaknesses in normal business processes Performed by Typically conducted by in-house staff using authenticated credentials; does not require a high skill level Best to use an independent outside service and alternate between two or three; requires a great deal of skill Value Detects when equipment could be compromised Identifies and reduces weaknesses Table 1.

While compliance mandates or basic security strategies may dictate that you need to patch at least monthly, vulnerability scans executed more frequently are recommended. This way, organizations can benefit significantly by gaining an accurate representation of their security profile.
Depending on the complexity of the vulnerabilities, some exploits can start appearing in the wild rather quickly. Once you establish a scan cadence and remediate where possible, you will have a good baseline of your security and compliance posture. The advantages of pen tests for an organization are based on the fact that vulnerability scanners are limited to identifying specific vulnerabilities that are present on any particular asset.
The true risk of those vulnerabilities may or may not be fully realized until a pen tester tries them within a specific environment. Instead of looking at just one vulnerability, pen testers will leverage multiple or chain multiple vulnerabilities together for a bigger effect.
Something that may not be rated as all that severe during a vulnerability scan may become a linchpin to a more insidious exploit when chained with multiple vulnerabilities in specific environments. Provides organizations a functional test of the network and application controls that help to secure their operations and data.
But remember: the scan is only as good as the threat intelligence and vulnerability data you put into it. The most perceptible risk is in not doing it frequently enough. But when it comes to pen tests, there is a serious risk of which to be aware. The most common risk stems from who a company chooses as its pen tester.
