Reasons

for a

Pentest

Every Redlings pentest is subject to strict guidelines and ethical principles.

1

Priorisierung von IT-Risiken

With a penetration test you can determine which existing vulnerabilities have the greatest impact on your web applications and network. on your web applications and network. Use your resources and time more efficiently.

2

Detection of vulnerabilities

Penetration tests attack your network and web applications like a hacker would - but without causing any damage. This allows you to find and fix vulnerabilities before the attackers do.

3

Implementation of Security Policy

Are important patches missing or are applications and operating systems not hardened? If your pentesters can show that applications and network areas with good implementation have fewer security vulnerabilities, this often has the effect of motivating them to follow the security guidelines.

4

Compliance requirements

Regulations such as PCI-DSS, but also ISO 27001/2 and others, may require regular penetration tests. Some contractual regulations may also contain such a requirement.

5

Konsequenzen eines Understand Cybersecurity Incidents

Penetration testing gives you unvarnished feedback on the possible consequences of an IT security incident such as a ransomware attack.

6

Evidence-based investment

Investments in security measures should always be supported with concrete evidence to demonstrate the value to the business. By showing your leadership team the value of an investment, you can justify your need for more resources

.
7

Training of the internal IT team

The results of a penetration test can help your developers and administrators make fewer mistakes. A pentest detects misconfigurations, programming errors and other vulnerabilities.

8

Protect your most important data and the trust of your customers

Company and customer data is considered the lifeblood of a business and can be extremely damaging in the wrong hands. With a pentest, your company can better protect its data assets and, if possible, prevent attacks.

9

Increase the effectiveness of your security investments

Our pentesters are certified experts in their field and often uncover ways in which existing (and paid for) security technologies can be better leveraged and protective efficacy enhanced.

Steps for a Penetration Test

1

Kick-Off

The project schedule is planned and prepared during the joint kick-off meeting. Among other things, the following points will be discussed:

  • Contact information exchange
  • Start and end date, test time window if applicable
  • Confirmation of the exact scope of the project
  • Presentation of the test item
  • Providing information for the testers (e.g. API documentation in case of an API test)
  • Agreement on the test environment and procedures
2

Penetration Test Execution

Now the security test takes place. Here, it usually consists of one (or more) commissioned test modules.

  • Internal Network Penetration Test
  • External Network Penetration Test
  • Web Application & Web-API penetration test
  • IoT/Hardware Security Assessment
  • Wifi Pentest
  • Active Directory Security Assessment
  • Red Teaming
  • Social Engineering
3

Report

The test results are compiled in a report. This will include, among others, the sections listed below:

  • Summary of the results and description of the framework of the project
  • Listing and description of security vulnerabilities found with risk assessment and remediation actions
  • Proof documentation on the security vulnerabilities, screenshots if necessary
4

Final Discussion

The penetration test and its result are discussed in a final meeting with all parties involved. We understand very well that the discovered and documented security vulnerabilities are only the first step. Concrete measures for the improvement of IT security must be derived and also implemented.

Häufige Fragen

What is a penetration test?

A penetration test, or "pentest" for short, is a security check that emulates an attack by a malicious party on a network or application to identify security vulnerabilities. This test is coordinated in advance and conducted in such a way that no system is damaged. At the end of the test, you will receive a report that includes the problems and vulnerabilities found, along with suggestions on how to fix them.

How long does a pentest take?

Similar to cost, the duration of penetration testing depends on several factors. Penetration testing is a hands-on assessment that does not lend itself to short, quick sprints. At Redlings, we tend to have pentesting projects start at week or so, but many projects can extend over a much longer period of time. extend over a significantly longer period of time.

How much does a penetration test cost?

As with any business service, the cost of a penetration test varies significantly depending on several factors. significantly depending on several factors.

Scoping details such as network IP addresses, complexity and number of (web) applications and employees for social engineering are key factors in determining project size. Taking these variables into consideration, our team works diligently to, align the scope details with your organization's security requirements.

Nevertheless, some empirical values that can serve as an initial guide can be mentioned. A high-quality, professional pentest performed by experts usually costs usually from about €10,000, but can be for large projects also significantly above this amount.

Redlings also offers discounts for multi-year contracts ("continuous pentesting") to ensure, that your company has a consistent pentesting partner, and can can stretch the security budget further.

How is the scope of a penetration test defined?

The scope of a penetration test should always be jointly adapted to the specifics of the company as well as the system to be tested.

In the case of a Web application, the scope often consists of the server and operational landscape as well as the user interfaces and APIs. Often, there are enterprise applications that have been specifically was written and that you want to have looked at.

Other considerations also play a role in a network pentest. In particular, the scope you choose should include mission-critical systems that would Could compromise security in the event of a compromise, e.g. because they store sensitive data, such as user information, passwords or customer data.

How is a vulnerability scan different from a penetration test?

Unlike penetration testing, vulnerability assessment does not determine in detail whether the vulnerability can actually be exploited or what impact it has. A vulnerability scan usually uses automated vulnerability scanners such as Nessus or even Nmap. Vulnerability scanners only cover standard scenarios and do not take into account the specifics of the IT infrastructure in question.

Vulnerability scans are therefore more of a first step in the technical analysis of vulnerabilities than a complete process for securing systems. They are also often used as part of a security audit or as one of the first steps in penetration testing. In all cases, penetration testing goes further and examines the discovered vulnerabilities in detail.

The pentester attempts to exploit the vulnerabilities and assess the resulting opportunities for the attacker. This helps determine the impact of a vulnerability. Due to the manual nature of a penetration test and the creativity of the pentester, the chances of finding serious vulnerabilities are much higher with professionally conducted penetration tests than with standardized vulnerability scans.

What is the difference between a penetration test and a vulnerability scan?

Both penetration testing and automated vulnerability scanning are useful tools for identifying technical risks and security vulnerabilities. Although they are different testing methods, they complement each other and should both be performed.

A vulnerability scan is an automated, low-cost method for testing common network and server vulnerabilities. This is sometimes referred to as automated pen testing. There are many automated tools available, and most can be easily configured by the end user to scan for published vulnerabilities on a scheduled basis. While an automated vulnerability scan is very efficient and cost-effective at identifying common vulnerabilities such as missing patches, service misconfigurations, and other known vulnerabilities, they are not as accurate at verifying the correctness of vulnerabilities, nor do they fully determine impact through exploitation. Automated scanners are more prone to reporting false positives (falsely reported vulnerabilities) and false negatives (unidentified vulnerabilities, especially those affecting web applications). Automated vulnerability scanning is mandated by the Payment Card Industry Data Security Standard (PCI DSS).
Well-known vulnerability scanners include and OpenVAS. Examples of scanners that specialize in finding web application vulnerabilities are Netsparker Security Scanner and Acunetix Vulnerability Scanner.

A penetration test focuses on the environment as a whole. In many ways, it picks up where scanners leave off to provide a comprehensive analysis of the entire security posture. Although scripts and tools are used by a penetration tester, their use is largely limited to reconnaissance activities. The majority of a penetration test is manual in nature. A penetration test identifies vulnerabilities that scanners cannot detect, such as vulnerabilities in wireless systems, vulnerabilities in web applications, and vulnerabilities that have not yet been disclosed. In addition, a penetration test involves attempts to securely exploit vulnerabilities, escalate privileges, and ultimately demonstrate how an attacker could gain access to sensitive information assets. Penetration testing also often involves the use of company-specific "test scenarios."

Penetration testing and automated vulnerability scans both serve a purpose, and both types of tests belong in a comprehensive vulnerability assessment program. Automated vulnerability scans should be performed at regular intervals, ideally at least weekly, while network penetration tests should be scheduled quarterly or when significant changes to the environment are planned.
