WHAT IS

PENETRATION TESTING?

Penetration Testing is a legal, structured procedure to evaluate the security posture of an organization. The practice simulates an attack against the security infrastructure of the enterprise, such as its network, applications, and users, to identify the exploitable vulnerabilities. It determines the efficacy of the company’s security policies, controls, and strategies. To strengthen the system, penetration testers proactively analyze for design flaws, technical weaknesses, and other vulnerabilities. The results of the vulnerability assessment are then comprehensively documented for executive management and the company’s technical audience.

Penetration Testing Phases

Phase 1:
Pre-attack Phase
Phase 2:
Attack Phase
Phase 3:
Post-Attack Phase

Phase 1: Pre-attack Phase

Research (Information Gathering)
In the initial phase, the penetration tester gathers general information about the security system and in-scope targets.

Phase 2 – Attack Phase

Targeting/Exploiting
The gathered data then used to locate ports and services. After this, the pen tester conducts the vulnerability assessment to gain more knowledge on its targeted system. The last part of the phase deals with heavy action – exploitation. Professionals use their expertise to attack and exploit resources.

Phase 3 – Post-Attack Phase

Documenting and Reporting
During the post-attack phase, the penetration tester submits a detailed report on all the findings and solutions to eliminate the potential threats.

Responsibilities of a

Penetration Tester

The common roles and responsibilities of a penetration tester are summarized here
  • Conducting a penetration test and risk assessment on the targeted system.
  • Performing security audits to evaluate whether the organization fits the defined security policies and standards.
  • Analyzing drafted security policies to make amendments.
  • Writing thorough reports on the findings of organized penetration tests.

Types of

Penetration Testing

Black Box Penetration Testing White Box Penetration Testing Gray Box Penetration Testing
Required knowledge A penetration tester has no previous knowledge of the system to be tested. A penetration tester has complete knowledge of the system to be tested. A penetration tester has limited knowledge of the system to be used.
Classification * Blind Testing – It’s a time-consuming and expensive process, where the penetration testing team provided with limited or no information.
* Double-Blind Testing – A few in the firm know about the pen test to be conducted. It evaluates security monitoring, attack identification, and response.
* Announced Testing – Penetration testing conducted after the full co-operation from the IT team.
* Unannounced Testing – The organization conducts the test without the knowledge of the IT staff.
No specific types
Turnaround Time It is time-consuming, requiring a considerable amount of time. It reveals vulnerabilities and bugs more quickly. It needs lesser time than black-box penetration testing.
Appropriate Testing Type (based on demand, goal, time, and available resources) Test to be conducted for evaluating the security stance of the organization. It uses the methodologies of an attacker. White and Gray box penetrating testing are used to save time and resources.
Required Qualification and Skills * They need to have a few years of experience to get qualified for the job.

  • Web application architecture

Different ways to conduct a

Penetration Test

Penetration testing can be performed in two ways – Automated Penetration Testing and Manual Penetration Testing.

Automated Penetration Testing
In automated penetration testing, various open-source and commercial tools are used to conduct the test.
Manual Penetration Testing
In manual penetration testing, an individual or a group of individuals perform the test.

Creating a career path in penetration testing

How penetration testing
differs from ethical hacking?

In general expression, people use penetration testing and ethical hacking interchangeably, but there’s a fine line between them. Penetration testing is a formal procedure, concentrating on finding vulnerabilities in an organization’s security infrastructure while ethical hacking is an umbrella term. The latter includes an attacker’s tools and TTP (Tactics, Techniques, and Procedures). To put it in simple words, penetration testing is a subset of ethical hacking.

Ethical Hacker

Penetration Tester

Ethical hacking, includes all attack vectors, hacking methods, and related tools Pen testers assess the security of a specific aspect of information systems as defined by a scope document
Have visibility to organization’s infrastructure 

 

They’re generally provided with limited or no information of organization’s infrastructure
Continuous engagement to ensure defense-in-depth One-time engagement for a limited duration
An ethical hacker should have detailed knowledge of TTP and various penetration testing tools to imitate the steps of a cybercriminal. A penetration tester needs to have sound knowledge of the dedicated domain or specific area for conducting pen-testing.
Required to assist blue teams and Incident handling teams in incident containment and validation No responsibility with regards to security configuration and incident handling
No mandatory requirement to be an expert in report writing. Penetration testing comes with fool-proof report writing.

Advanced Penetration Tester (APT) training program [Recommended for L|PT (Master)]

The Advanced Penetration Tester (APT) is the recommend training program, to prepare for the gruelling L|PT (Master) challenge. This course does not just provide you targets that are directly reachable, there are filters in place that you have to first map the attack surface of and identify a weakness to go through the filter, then once you have made it through the filter you next have to determine how you can gain access THROUGH the filter, this requires you to customize payloads and try and get them in and out of the filter. The APT ranges have multiple machines and some of these machines are behind layers of protection, so you have to identify this and once you do you have to find a way to gain access, then from the first point of access you have to pivot to another network and then assess that network. This requires manual manipulation and is not part of any of the other classes. Some of these programs claim to have pivoting, but it does not involve gaining access through a filter first. This prepares the tester for an environment where the administrator has placed protections in place such that the machines are not directly reachable which are more and more common obstacles a tester faces.

The APT focuses on the mapping of the attack surface and from that what the risk is to the client, we do this in the form of an understanding of how the networks are assessed, not just the machines. This is important, because in testing the client wants to know what you discover on the network and not as much about the methods of exploitation, so in the APT you will get experience with the analysis of the data and this is what is required for industry penetration testers, the process of security testing of which penetration testing is a component has not changed, but what has changed is the tools that are available and the targets, so in the APT we try to give you as many different targets as possible, because that is what will make you into a much better industry level penetration tester.

  • It evaluates the efficiency of in-use security controls.
  • It determines the scope of a potential attack.

How much does a pen tester make?

If you have previous experience with Blockchain and believe you can finish it in less than 3 months, you can choose the one-time payment option which allows you to get access to a fully customized plan.

This means that you will be able to work at your own pace from the moment you sign up for the course.

How long does a pen test take?

The overall time required to conduct a pen test is dependent on the size and complexity of the network. Based on this, the process may take one to four weeks.

How is penetration testing done?

Penetration testers imitate the steps of a threat actor by penetrating the security infrastructure of an organization.

What do you mean by penetration testing tools?

Penetration testing tools can be defined as the programs used to look for security threats in an organization.

What is physical penetration testing?
