External Network Penetration Testing

Assess your external nettwrok for security vulnerabilities with a comprehensive security test

External Network Penetration Testing

Our security solution is specifically designed to protect the external assets of any organization. By combining automation with manual network penetration testing, we are able to quickly identify any vulnerabilities that may exist due to improper configuration of operating systems or open network services. These vulnerabilities could potentially be exploited to gain unauthorized access to the network or key servers from the internet. Our testing covers web servers, VPNs, firewalls, routers, mail servers, and a wide range of networking services to ensure the security of your organization.

It is crucial for organizations to understand their vulnerabilities and the ways that hackers may attempt to exploit them. One way to do this is through external network penetration testing, which involves actively evaluating the security of an organization’s internet-accessible perimeter infrastructure. This helps identify potential opportunities for attackers to gain access to sensitive information or compromise business-critical systems.

External networks may include servers, VPN login portals, webmail portals, and any other portals that can be accessed via a web browser. During a pentest, Cyber Legion’s team of experts will use real-world attack methods and tools to try to breach external systems and gain access to sensitive information.

The testing will be carried out without access to detailed network or infrastructure diagrams and without any accounts or additional user information (unless specifically included in the scope of the test). Our testers follow a standard methodology based on the Open Source Security Testing Methodology Manual (OSSTMM). The external network test can be focused on a specific IP range or include broader reconnaissance using open-source intelligence (OSINT).

Security Testing Methodology – What do we test for?

Types of Pentesting

  • 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, these details can be included 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

Network Pentesting

As pentesters, we know that any information about the system being tested is valuable. By understanding the software that is running on someone’s web server, we can more effectively find exploits that are specific to that version of the software, rather than trying a variety of exploits and hoping one works.

At Cyber Legion, we offer flexible testing options to meet our customers’ needs. However, if you want maximum impact and a white-box test, here’s what we recommend for preparing the scope:

  • Identify the assets to be tested, such as specific parts of the external network
  • Determine the IP addresses associated with those assets
  • Provide those IP addresses as the scope of the test

It’s important to make sure the provided IP addresses actually belong to the company, and to notify any third-party vendors connected to those assets. To increase the value of external assessments, it can also be helpful to monitor public IPs from which attacks may be launched in order to better identify and respond to future attacks.

We follow frameworks and best practices such as OWASPASVS, or OSSTMM. Typically port scanning activities are performed, followed by the search for web servers. Determining the software and version in use for each service is also helpful in identifying misconfigurations or vulnerabilities.

Security Testing Methodology – What do we test for?

Several testing stages follow that result in an effective test. By using our platform’s cyber intelligence capability together with expert penetration testing knowledge, Informer’s testers identify your true attack surface with depth.

  • Asset discovery – asset mapping is using Informer’s discovery tools and intelligence engine
  • Service identification – identifies live services that are accessible from the internet
  • Vulnerability analysis – each service is analyzed in detail to identify misconfigurations and software vulnerabilities
  • Service exploitation – exploitation will be performed to verify vulnerabilities and gain access to infrastructure
  • Gain additional access & pivoting – successful exploitation will be used to gain further access to connected networks and hosts

FAQ’s

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.
