Network penetration testing is a crucial procedure that helps identify security flaws, network weaknesses, and threats that could damage any organization’s networks, website servers, and other applications if they are attacked by hackers. It’s a crucial step in determining how secure your network is by simulating attacks to gain unauthorized access to the target network thereby assessing the current state of network security.
Black Box, often referred to as behavioral testing or external testing, is a form of software testing technique wherein no prior knowledge of the internal code structure, implementation specifics, or internal routes of an application is necessary. It focuses on the application’s input and output and is entirely dependent on the specifications and requirements of the software.
White Box testing examines a software’s underlying structure, coding, and architecture to validate the input-output flow and improve the application’s design, security, and utility. Testing of this kind is sometimes referred to as internal testing, clear box testing, open box testing, or glass box testing because testers can see the code.
Gray box testing, which combines black box and white box testing, is a software testing approach used to test an application while only having a general understanding of its core code. It searches for and identifies context-specific errors that the application’s poor code structure has produced.
The client’s scope must be clearly defined before an application assessment can be conducted. At this point, open dialogue between the company and the client is recommended to build a secure platform upon which to conduct assessments.
At this step, a variety of OSINT (Open-Source Intelligence) tools is used and tactics are to gather as much data as they can on the target. The gathered data will help us comprehend how the relationship functions, which will enable us to precisely assess the risk as the engagement develops.
At this point, we combine computerized resources and tools with various data collection methods to create more advanced data. Any potential attack vectors are carefully examined by our experts. In the following step, the acquired data from this stage will serve as the foundation for its application.
To uncover all potential attack paths and vulnerabilities, we launch both a manual and an automated security scan in this step. To assess the application’s security, we then execute exploits against it. For a high degree of penetration, we employ several techniques, open-source scripts, and internal tools. To secure your application and its data, all of these are carefully carried out.
This is the last step in the entire assessment procedure. This stage involves gathering all acquired data, analyzing it, and providing the client with a complete, comprehensive breakdown of our results. A comprehensive analysis of all the hazards will be included in the full report, and the final report will also list all the application’s strengths and shortcomings.
The network penetration test should be carried out at least once a year or whenever one of the following situations arises:
a) The addition of, or a material modification to, infrastructure or applications.
b) End-user access policies being changed (permissions or roles).
During a pen test, an outsider or hacker is made to pretend they are getting access to the system of the organization. A subset of pen test procedures called a vulnerability scan is used to evaluate a network and connected systems for a predetermined list of known vulnerabilities. While vulnerability scans focus on the system flaws already present, a pen test will simulate a 'live' threat or assault.
Network VAPT is performed by NIST SP800-115, PTES, and CIS Benchmarks requirements.
In addition to routine VAPT, it's advisable to do a configuration audit and device-level security analysis by the OEM's suggested security policies and procedures.
