Network Penetration Testing

Deep-dive, manual network penetration testing performed by experienced and certified penetration testers

Overview

The primary objective for a network penetration test is to identify exploitable vulnerabilities in networks, systems, hosts and network devices (ie: routers, switches) before hackers are able to discover and exploit them. Network penetration testing will reveal real-world opportunities for hackers to be able to compromise systems and networks in such a way that allows for unauthorized access to sensitive data or even take-over systems for malicious/non-business purposes.

Our penetration testing methodology includes an attack simulation carried out by our highly trained security consultants in an effort to:

  • Identify security flaws present in the environment
  • Understand the level of risk for your organization
  • Help address and fix identified network security flaws

RedTeam Security network penetration testers have had experience supporting network, systems and hosts —not just trying to break them. They leverage this experience to zero in on critical issues and provide actionable remediation guidance.

As a result of our penetration tests, you’ll be able to view your systems through the eyes of both a hacker and an experienced network security professional to discover where you can improve your security posture. Our consultants produce findings in written reports and provide your team with the guidance necessary to effectively remediate any issues we uncover.

  • Approach

    Approach

    RedTeam Security’s network penetration testing service utilizes a comprehensive, risk-based approach to manually identify critical network-centric vulnerabilities that exist on all in-scope networks, systems and hosts.

    1. Information Gathering
    2. Threat Modeling
    3. Vulnerability Analysis
    4. Exploitation
    5. Post-Exploitation
    6. Reporting

    Using this industry-standard approach, RedTeam’s comprehensive method covers the classes of vulnerabilities in the Penetration Testing Execution Standard (PTES) and the Information Systems Security Assessment Framework (ISSAF) including, but not limited to: CDP attacks, MIME testing, DNS enum/AXFR, SMTP relay, SNMP recon, port security, brute force, encryption testing and more…

    Manual Testing vs Automated Testing

    RedTeam’s approach consists of about 80% manual testing and about 20% automated testing – actual results may vary slightly. While automated testing enables efficiency, it is effective in providing efficiency only during the initial phases of a penetration test. At RedTeam Security, it is our belief that an effective and comprehensive penetration test can only be realized through rigorous manual testing techniques.

    Tools

    In order to perform a comprehensive real-world assessment, RedTeam Security utilizes commercial tools, internally developed tools and the same tools that hacker use on each and every assessment. Once again, our intent is to assess systems by simulating a real-world attack and we leverage the many tools at our disposal to effectively carry out that task.

    Reporting

    We consider the reporting phase to mark the beginning of our relationship. RedTeam strives to provide the best possible customer experience and service. As a result, our report makes up only a small part of our deliverable. We provide clients with an online remediation knowledge base, dedicated remediation staff and ticketing system to close the ever important gap in the remediation process following the reporting phase.

    We exist to not only find vulnerabilities, but also to fix them.

    Remediation & Re-testing

    Simply put, our objective is to help fix vulnerabilities, not just find them. As a result, remediation re-testing is always provided at no additional cost.

  • Methodology

    methodology-chart-networkMethodology

    Each and every network penetration test is conducted consistently using globally accepted and industry standard frameworks. In order to ensure a sound and comprehensive penetration test, RedTeam leverages industry standard frameworks as a foundation for carrying out penetration tests. At a minimum, the underlying framework is based on the Penetration Testing Execution Standard (PTES) but goes beyond the initial framework itself.

    Intelligence Gathering

    The information-gathering phase consists of service enumeration, network mapping, banner reconnaissance and more. Host and service discovery efforts results in a compiled list of all accessible systems and their respective services with the goal of obtaining as much information about the systems as possible.

    Host and service discovery includes initial domain foot printing, live host detection, service enumeration and operating system and application fingerprinting. The purpose of this step is to collectively map the in-scope environment and prepare for threat identification.

    Threat Modeling

    With the information collected from the previous step, security testing transitions to identifying vulnerabilities within systems. This begins with automated scans initially but quickly develops into deep-dive manual testing techniques. During the threat-modeling step, assets are identified and categorized into threat categories. These may involve: sensitive documents, trade secrets, financial information but more commonly consist of technical information found during the previous phase.

     Vulnerability Analysis

    The vulnerability analysis phase involves the documenting and analysis of vulnerabilities discovered as a result of the previous steps. This includes the analysis of out from the various security tools and manual testing techniques. At this point, a list of attractive vulnerabilities, suspicious services and items worth researching further has been created and weighted for further analysis. In essence, the plan of attack is developed here.

    Exploitation

    Unlike a vulnerability assessment, a penetration test takes such a test quite a bit further specifically by way of exploitation. Exploitation involves actually carrying out the vulnerability’s exploit (ie: buffer overflow) in an effort to be certain if the vulnerability is truly exploitable. During a RedTeam Security network penetration test, this phase consists of employing heavy manual testing tactics and is often quite time-intensive.

    Exploitation may include, but is not limited to: buffer overflow, SQL injection, OS commanding and more…

    Reporting

    The reporting step is intended to deliver, rank and prioritize findings and generate a clear and actionable report, complete with evidence, to the project stakeholders. The presentation of findings can occur via Webex or in-person – whichever format is most conducive for communicating results. At RedTeam Security, we consider this phase to be the most important and we take great care to ensure we’ve communicated the value of our service and findings thoroughly.

  • Deliverables

    Deliverable

    At RedTeam Security, we consider the Delivery / Reporting phase to be the most important and we take great care to ensure we’ve communicated the value of our service and findings thoroughly. The deliverable consists of an electronic report that includes several key components including, but not limited to: Executive Summary, Scope, Findings, Evidence, Tools and Methodology. In addition to the report, a raw file in comma-separated value (CSV) format is also provided in an effort to optimize the remediation and management of any identified findings.

    Findings are communicated in a stakeholder meeting and typically presented in-person or virtually via Webex — whichever medium is most conducive for communicating results effectively. During this time, RedTeam Security consultants will walk through the report, in detail, to ensure all findings and their corresponding description, risk rating, impact, likelihood, evidence and remediation steps are thoroughly understood. While this typically involves a single meeting, there is no limitation to that number. The key underlying message is that all information is clearly understood and that a roadmap toward remediation / mitigation is crystal clear.

  • FAQ

    Frequently Asked Questions

    Why should should I conduct a penetration test?

    A penetration test is a simulated attack from the perspective of a bad actor, such as a malicious hacker. The objective is to simulate a cyber security attack and attempt to uncover security vulnerabilities that might otherwise be discovered by hackers. In doing so, you would gain valuable insight into the security posture of the in-scope assets and be able to fix them before hackers are able cause serious damage by exploiting them.

    How long does it take to conduct a network penetration test?

    The overall time depends on the size and complexity of the in-scope network(s). That said, most tests take anywhere from one week to four weeks, start to finish.

    How much does a network penetration test cost?

    We get this question a lot and it’s not easy to answer until some level of scoping has been performed. Our scoping process is quick, online and painless. But overall, the complexity of the application will ultimately determine its cost. For example, when determining the work effort, we take the following into account: number of live IP addresses, etc.

    What’s the difference between a Penetration Test and a Vulnerability Assessment?

    We get this question a lot as well. Short answer: Exploitation and Post-Exploitation. Vulnerability assessments do not involve Exploitation while penetration testing goes well beyond a vulnerability assessment and into Exploitation and Post-Exploitation phases.
