Who is pentester ?

 

Penetration Tester Overview

A penetration tester is a network security expert who attempts to break into or discover potential exploits in various computer systems and software.They can be thought of as a form of ethical hacker.They are typically expected to conduct a number of tests, most of which are focused on network penetration, and then write up evaluation reports based on their findings.
While they will frequently conduct pre-determined sorts of tests, they will also develop their own tests for a significant amount of the time, which demands creativity and inventiveness, as well as a high level of technical understanding and know-how.

  

You'd be expected to conduct formal tests on web-based apps, networks, and other sorts of computer systems on a regular basis as a penetration tester.Physical security inspections of servers, computer systems, and networks will also be expected of you.You'll be conducting regular security audits from both a logical/theoretical and a technical/hands-on stance in addition to these tests and assessments.In most professions, you'll be expected to work on wireless network security, database security, software development security, and/or company secrets security.Each of these fields is distinct, and many people opt to focus on just one or two. 

 

What is penetration testing?

Penetration testing entails an authorized simulated attacks with the goal of determining how to improve the system's security.A penetration tester's goal is to discover security flaws in a system before a hacker does.

 

Penetration testing is used to avoid what is known as "black-hat hacking," or breaking into a system with malevolent intent.A black hat hacker's goal could be to install malware, kidnap systems, or steal passwords, credit card numbers, or other personal information.  

By breaking a number of application systems, such as application protocol interfaces (APIs) and frontend/backend servers, a penetration tester will imitate these actions.This procedure can be carried either manually or with the help of automated software.Penetration testing reveals information that can be utilized to fine-tune security and avoid unethical hacking. 

An ethical hack is often carried out by a penetration tester in a five-step process:

• Gathering and analyzing open source intelligence (OSINT) – information from public sources – to find information disclosures (when an application reveals sensitive information).
• Providing expertise on security and testing defensive mechanisms for the organization.
• Conducting assessments on a wide range of technologies, using both automated tools and manual approaches
• Developing scripts, tools, and methodologies to improve testing processes.
• Testing both wired and wireless networks for any security vulnerabilities.
• Examining results from the assessment to identify findings and develop a holistic view of the system.
• Identifying the root cause of both technical and non-technical findings.
• Publishing a report that documents the findings from the assessment while identifying potential countermeasures.
• Keeping track of and communicating findings from multiple assessments.
• Communicating the methods used to complete assessments.
• Providing technical support in the organization. 

 

There are many useful tools that penetration testers use to carry out their tests. These include Kali Linux, nmap, Metasploit, Wireshark, and John the Ripper, all of which are designed to help pen testers find weaknesses in a system.
