Why Automated Pen Tests are Not Enough

With the increasing number of networks, systems, and applications, the vision of performing a Network Pen Test on every subnet and every system or performing an Web App Pen Test on every web app may seem impossible for many organizations, especially those with limited budgets and limited resources. With all that said, network and web application security risks will not be mitigated by automated testing. All of this will lead to extremely hard choices when trying to establish cost-effective strategies for network and web application security.

Almost every cybersecurity professional within the industry can agree that networks, systems, and web applications will not be properly secured by only running automated pen tests and automated vulnerability scans. Pen test companies that only offer automated pen tests should be avoided. This article will cover the numerous flaws of “automated pen tests” and automated scanning. This article will also provide organizations with potential solutions while taking in considerations such as limited resources and/or limited budget while still allowing organizations to properly secure their networks, web apps, and systems from cyberattacks.

What Are the Options for Pen Test Companies?

Pen test companies may offer different options for security testing. Three of the main security testing approaches vary in cost, accuracy, and depth. These three methods can be utilized at different frequencies as they can yield different results. These three methods can be combined together to build a more effective cybersecurity program.

  • Automated Pen Test / Automated Vulnerability Scanning
  • Automated Vulnerability Scanning with Manual Validation
  • Manual Pen Test (Vulnerability Scans leveraging Manual Validation, with additional Manual Pen Testing)

Is All Automated Scanning Bad?

No. Automated scanning can be a great starting point for organizations who lack a cybersecurity budget and cannot benefit from frequent manual penetration testing of all of their networks, systems, and applications. However, automated penetration testing and automated scanning should not be the only proactive actions taken. Manual penetration testing is a must!

Which Approach Should Organizations Take?

Some organizations will try to use an approach based on risk to help decide which kind of security test should be used. This approach can lead organization to conclude that either only automated penetration testing or only automated vulnerability scanning would be okay for some company networks, systems, and web applications. The truth is, this is not acceptable. A majority of networks, systems and web applications still need frequent manual penetration testing. The frequency of the manual penetration test may be set based on other factors such as the frequency of routine vulnerability scans.

Relying on Automated Pen Tests Exposes Many Organizations to Cyberattacks

Pen test companies that only offer automated penetration testing should be avoided. While automated penetration testing and automated vulnerability scanning may help organizations, automated testing should never be the sole method to test an organization’s cybersecurity posture. Many networks contain unique systems and configurations. Most web applications contain business logic which is unique and automated pen testing and automated scanning cannot contextualize. The automated verifications by automated penetration testing and automated scanning cannot identify many critical vulnerabilities within web applications.

Two example vulnerabilities include Authentication Bypasses and Weak Access Controls. These two example vulnerabilities may have devastating results if they are used by attackers and these example vulnerabilities are often related to the actions and properties found within unique web applications. These are only two examples of critical vulnerabilities that would require manual penetration testing to be discovered. Organization that rely on automated penetration testing or automated vulnerability scanning would be blind to these types cyberattacks.

Why are Automated Pen Tests Bad?

Unfortunately, some organizations have started relying on automated penetration testing and automated vulnerability scanning which can lead the entire organization to have a false and misleading sense of their security posture. Leadership assumes that the company’s networks and web application have been properly secured, but numerous critical vulnerabilities remain on the network and within the web applications.

Automated Pen Testing (Even With Some Manual Validation) Can Leave Organizations Exposed to Cyberattacks

Some organizations receive automated penetration testing and think that the networks and web applications no longer require manual penetration testing. Automated penetration testing, even with manual validation, has left organizations exposed to numerous cyberattacks. Pen test companies that only offer automated penetration testing should be avoided.

Case Study #1: Public Web Application

The findings below represent a small sample of security issues that would never have been identified or fixed if the company had only relied on automated penetration testing and automated vulnerability scans. If the organization had relied only on the automated testing, the organization would have been left vulnerable to cyberattacks.

Found During an Automated Penetration Test

  • High - Cross-Site Scripting (False Positive)
  • High - Encryption Is Not Enforced
  • Medium - Outdated Software Components

Found During a Manual Penetration Test (Missed During an Automated Penetration Test)

  • Critical - Authorization Bypass
  • Critical - API Does Not Require Authentication
  • Critical - Privilege Escalation
  • High - Sensitive Content Publicly Exposed
  • Medium - Client-Side Controls Can Be Bypassed
  • Medium - Outdated Software (JavaScript v1.4.0)
  • Low - Information Disclosure

The automated penetration test missed crucial vulnerabilities allowing attackers access to sensitive information.

Manual Pen Tests on an Annual Basis

It is required that all networks and web apps be tested manually by certified and qualified penetration testers at least one time a year. When you consider today’s constantly developing cyber threats, we recommend for networks and web applications to be tested manually twice a year and sometimes even quarterly. This allows organizations to proactively stay ahead of methods used to bypass security measures within networks and web applications. This is also why standards including PCI-DSS require both an annual external penetration test and an annual internal penetration test to be compliant. PCI-DSS also states that both the external and internal tests must include network testing and web application testing.

Manual Pen Tests After Significant Changes

It is also crucial that all networks and web applications are tested manually when new devices are added, when new functionality is introduced, and when major / significant changes are implemented to the supporting infrastructure. This is because additional vulnerabilities could be introduced which could leave the organization vulnerable to cyberattacks. PCI-DSS requires that penetration testing be performed after all significant changes. This is separate from the required annual penetration tests.

Automated Pen Tests and Automated Vulnerability Scanning

Automated penetration testing and automated vulnerability scanning may identify some types of vulnerabilities. Automated scanning may also be efficient at finding specific misconfigurations. The automated validations are sometimes performed by leveraging databases containing thousands of vulnerabilities related to different technologies along with particular flaws related to various versions of software that may be installed. Automated testing and scanning may be run on a routine basis which may help in-between manual penetration tests.

Automated Scans with Manual Validation

One of the largest issues of automated penetration testing and automated vulnerability scanning is the large number of misleading false positive items that the automated testing and scanning can generate. This often leads to wasting company resources since the teams may spend time investigating and attempting to fix vulnerabilities that may not actually exist. Furthermore, teams may spend time remediating items that present little risk for the organization. A certified penetration tester may manually validate items found in automated penetration tests and automated vulnerability scans to adjust the risk ratings. This may help prioritize next steps and help save company resources and money.

Automated Pen Tests and Automated Scans with Manual Validation

One of the most important items to note is that manually validating items found during automated penetration tests and automated scans does not increase the testing depth, nor does it increase the depth of analysis. This is why automated penetration testing with manual validation will not make the tests as dependable as manual penetration testing.

Cons of Automated Pen Test Companies

The following lists some of the cons of automated penetration testing:

  • The automated testing tool is not perfect
  • There are higher chances of false positives
  • There are higher chances of false negatives
  • Testing may not be considered as an independent attestation
  • Testing can only scan for the test cases given by the security vendor
  • Testing has a fixed number of results as programmed by the vendor
  • The automated tool cannot analyze situations that a human can analyze

Pros of Manual Pen Test Companies

The following lists some of the pros of manual penetration testing:

  • In-depth manual testing of networks
  • In-depth manual testing of systems
  • In-depth manual testing of web applications
  • Skilled penetration testers can analyze situations better
  • Skilled penetration testers can think like the hacker

Manual Pen Test Companies for the Win

After reading and analyzing this article, hopefully it is clear to you why manual penetration testing is the clear winner and why automated penetration testing alone will never be comparable to a manual penetration test. If you had an automated approach to read and analyze this article, which method would your script choose?

Do Not Be Fooled by an Automated Pen Test Companies

If you are investing in your organization’s security by undergoing a penetration test, ensure that you are actually receiving a manual penetration test. Do not let firms misguide you into thinking that an automated vulnerability scan or an automated penetration test can detect all of your vulnerabilities. If the firm you have hired does not use manual testing methods from a credentialed penetration tester during the penetration test, you are not receiving a quality penetration test. Acceptable credentials may include OSCP, OSWP, GXPN, GPEN, GCPN, GWAPT, GMOB, AWS CSS, and others. Contact Central InfoSec today to learn more about our quality-focused penetration testing services.
