Optimize Your Testing Scope for Maximum Impact with Cyber Legion

As expert pentesters, we understand that even the smallest piece of information about the system being tested can be valuable in uncovering potential exploits. At Cyber Legion, we offer flexible testing options to meet our clients’ needs, ensuring that we identify vulnerabilities that may exist due to improper configuration of operating systems or open network services.

Types of Pentesting

  • At Cyber Legion, we offer flexible testing options to meet our clients’ needs. The types of pentesting we offer are:

    • Black Box: No prior access is given during an external network pentest unless explicitly outlined in the scope.
    • White Box: Specific access is given during an external network pentest.
    • Gray Box: No access is given to start, but some access is given after certain tests are performed.

Further, we can include the following details in the scope of the desired pentest with gray box and white box testing:

  • Network diagrams
  • Infrastructure diagrams
  • Accounts (even temporary accounts for pentests)
  • User information

Optimal Pentesting Approach

To achieve maximum impact and comprehensive results, we recommend a white-box test that covers the following:

Identify Specific Assets to Be Tested

To ensure that our testing is focused and effective, we work with our clients to identify the assets that need to be tested. This can include specific parts of the external network or other critical assets that need to be evaluated.

Determine Associated IP Addresses

Once we have identified the assets to be tested, we determine the IP addresses associated with those assets. This ensures that our testing is conducted on the correct systems and that we can identify any potential security gaps that may exist.

Verify Ownership of IP Addresses

We take the necessary steps to ensure that the IP addresses we are testing actually belong to the company. This involves verifying ownership and notifying any third-party vendors connected to those assets to prevent any disruptions to their operations.

Follow Best Practices and Frameworks

At Cyber Legion, we follow industry-standard frameworks and best practices, such as OWASP, ASVS, or OSSTMM, to ensure that our testing is comprehensive and effective. Our methodology typically involves port scanning activities, followed by the search for web servers. We also determine the software and version in use for each service, which can help identify misconfigurations or vulnerabilities.

Monitor Public IPs for Future Attacks

To increase the value of external assessments, we monitor public IPs from which attacks may be launched. This allows us to better identify and respond to any future attacks, giving our clients the peace of mind they need to focus on their core business objectives.

External Network Security Testing based on Multiple Security Frameworks Methodologies

When it comes to External Network Penetration Testing, the following test techniques can be used based on the aforementioned methodologies and standards:

  1. Information Gathering: This involves collecting information about the target organization’s network and systems. This can be done using tools such as Nmap, Shodan, and Maltego. The objective is to identify potential attack vectors and vulnerabilities in the network.

  2. Vulnerability Scanning: Once the target network is identified, vulnerability scanning is conducted to find known vulnerabilities in the system. This can be done using tools such as Nessus, OpenVAS, and Retina. The objective is to identify security holes that can be exploited to gain unauthorized access to the network.

  3. Exploitation: Exploitation is the process of attempting to gain unauthorized access to the target system by exploiting the vulnerabilities identified during the vulnerability scanning phase. This can be done using tools such as Metasploit, Core Impact, and CANVAS.

  4. Social Engineering: Social engineering is the process of manipulating people to divulge sensitive information that can be used to gain unauthorized access to the target network. This can be done through techniques such as phishing, pretexting, and baiting.

  5. Password Cracking: Password cracking involves attempting to guess or crack passwords that are used to secure the target network. This can be done using tools such as John the Ripper, Cain and Abel, and Hydra.

  6. Web Application Testing: Web application testing involves assessing the security of web applications hosted on the target network. This can be done using tools such as Burp Suite, Acunetix, and WebInspect.

  7. Wireless Network Testing: Wireless network testing involves assessing the security of wireless networks hosted by the target organization. This can be done using tools such as Aircrack-ng, Wireshark, and Kismet.

  8. Post-Exploitation: Post-exploitation is the process of maintaining access to the target network after gaining unauthorized access. This involves using techniques such as privilege escalation, backdoor installation, and data exfiltration.

These are just a few of the test techniques that can be used during External Network Penetration Testing. The specific techniques used will depend on the scope of the test and the methodology being followed. It is important to follow a standard methodology to ensure that the test is comprehensive and effective.

Penetration tests, also known as pen tests, are conducted by ethical hackers in order to identify vulnerabilities in your company’s software and hardware systems. A web application pen test is a specific type of test that focuses on examining the endpoint of every web application in order to uncover potential weaknesses. These tests are becoming increasingly important as hackers are targeting web apps, browsers, and plug-ins that may contain sensitive financial or personal information. By conducting a pen test, you can ensure that your systems are secure and protect your company’s data from potential threats.

External penetration testing (also known as external network penetration testing) is a security assessment of an organisation’s perimeter systems. Your perimeter comprises all those systems which are directly reachable from the internet.

External penetration tests allow you to properly gauge your defenses and determine where it can be successfully hacked. The penetration test highlights cybersecurity exposures, which allows you to correct the issues before hackers can exploit them.

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.
