Internal Network Security Testing based on Multiple Security Frameworks Methodologies

Internal network security testing based on multiple security frameworks methodologies involves using multiple methodologies and frameworks to assess the security of an organization’s internal network. This approach helps to identify vulnerabilities and threats that may not be detected using a single framework or methodology.

Here are some of the commonly used security frameworks and methodologies that can be used in combination for internal network security testing:

  1. NIST Cybersecurity Framework – The NIST Cybersecurity Framework provides a structured approach to managing and reducing cybersecurity risk. It includes five core functions: identify, protect, detect, respond, and recover.

  2. Open Web Application Security Project (OWASP) – OWASP is a non-profit organization that provides tools, guides, and standards for web application security. The OWASP Top 10 is a widely used standard that identifies the top ten web application security risks.

  3. Payment Card Industry Data Security Standard (PCI DSS) – PCI DSS is a standard for securing payment card data. It includes requirements for network security, access control, and encryption.

  4. Center for Internet Security (CIS) Controls – The CIS Controls provide a prioritized set of actions that organizations can take to improve their cybersecurity posture. They cover a wide range of security domains, including network security, access control, and incident response.

  5. SANS Critical Security Controls – The SANS Critical Security Controls provide a framework for securing an organization’s assets, including hardware, software, and data. They focus on continuous monitoring, incident response, and vulnerability management.

When using multiple frameworks and methodologies, it’s important to tailor the testing approach to the specific needs of the organization. A thorough understanding of the organization’s IT infrastructure, business objectives, and risk profile is critical for designing an effective testing strategy.

Additionally, it’s essential to ensure that the testing approach aligns with relevant legal and regulatory requirements. This may include obtaining consent from employees and stakeholders, and ensuring that the testing does not disrupt critical business operations.

An internal network penetration test is a type of security assessment that simulates a real-world attack on an organization’s internal network infrastructure to identify vulnerabilities and weaknesses that could be exploited by malicious actors. The objective of this type of testing is to evaluate the effectiveness of an organization’s security controls and identify potential security gaps that could result in unauthorized access to sensitive data or network resources.

During an internal network penetration test, security professionals use a range of techniques and tools to identify vulnerabilities in network devices, servers, workstations, wireless networks, and applications that run on the internal network. The testing typically follows a predefined methodology that includes reconnaissance, vulnerability scanning, exploitation, post-exploitation, and reporting.

The results of an internal network penetration test provide organizations with valuable information about the effectiveness of their security measures and enable them to take proactive steps to remediate identified vulnerabilities before they can be exploited by attackers. By identifying and addressing security weaknesses, organizations can improve the overall security posture of their internal network infrastructure and reduce the risk of a security breach.

Internal network penetration testing is important for several reasons:

  1. Identifying vulnerabilities: Internal network penetration testing helps identify vulnerabilities and weaknesses in an organization’s internal network infrastructure. These vulnerabilities could be exploited by malicious actors to gain unauthorized access to sensitive data or network resources.

  2. Improving security posture: By identifying weaknesses and vulnerabilities, organizations can take steps to improve their security posture and reduce the risk of a security breach. This can help prevent financial loss, reputational damage, and legal repercussions.

  3. Compliance: Many regulatory standards, such as PCI DSS and HIPAA, require organizations to conduct regular security assessments, including internal network penetration testing, to ensure compliance with industry regulations.

  4. Demonstrating commitment to security: Conducting internal network penetration testing demonstrates an organization’s commitment to security and their willingness to take proactive steps to identify and address potential security risks.

  5. Mitigating insider threats: Internal network penetration testing can help identify potential insider threats by identifying vulnerabilities that could be exploited by insiders. This can help prevent data breaches and other security incidents caused by employees or contractors with malicious intent.

In summary, internal network penetration testing is important for identifying vulnerabilities, improving security posture, compliance, demonstrating commitment to security, and mitigating insider threats. By conducting regular internal network penetration testing, organizations can proactively identify and address potential security risks, reducing the risk of a security breach and protecting their sensitive data and network resources.

The Penetration Testing Framework (PTF) provides comprehensive hands-on penetration testing guide. It also lists usages of the security testing tools in each testing category. The major area of penetration testing includes: Network Footprinting (Reconnaissance) Discovery & Probing.

Our testers will contact you immediately by phone, email, and the dedicated Slack channel that we will use with you during the testing process.

This isn’t something we actively test for and we wouldn’t recommend testing for this. However, we will highlight vulnerabilities that could lead to a Denial of Service.

The network penetration testing process typically consists of five phases:

  1. Planning and Reconnaissance. The goal of this phase is to plan to simulate an attack. Understanding your company’s tech stack and systems is key.
  2. This refers to the investigation stage, where penetration testers use scanning tools, explore your systems and identify vulnerabilities of the network.
  3. Gaining Access. Having identified network vulnerabilities, the penetration testers use these security vulnerabilities to gain access to your business network. The pen testers then use these vulnerabilities to exploit your system.
  4. Persistent Access. After successfully gaining access to your system, the pen tester will maintain access long enough to accomplish the typical malicious hackers’ goals.
  5. Security Assessment Report. After the Network Penetration test, a report is prepared discussing the process itself together with the analysis. The report will outline the security vulnerabilities found and how to prevent future attacks.

The time that penetration testing takes depends on the size and complexity of your organization’s system structure, as well as the scope of the test itself. For the ‘average’ company, a network penetration test should take around three days. For a merchant processing millions of credit cards a year, for example, a pen test will take over a week, or possibly two.

It’s crucial to find out how vulnerable your network is before an attack happens. You can use the information collected to fix potential security flaws and keep your data safe from hackers.

The penetration testing cost depends on the facts identified during scoping, such as the agreed time, goals, technical resources, approach, and remedial support.
