We can confidently say that cybercriminals will always exist. Hackers are constantly looking for novel methods to target your site, your company, and your private details. Security breaches are happening more frequently now. Due to the expansion of the web, attackers now have more options to access your website or identify a security vulnerability through which to do so. Internal penetration testing is one of the finest ways to protect your company against security breaches and attackers.
What is internal penetration testing?
A form of penetration testing called an internal pentest, commonly referred to as an internal penetration test, involves testers attempting to attack a network from within. It’s intended to mimic the behaviors of an actual assault. An employee or someone with exposure to the network’s foundation does an internal pentest.
The purpose of an internal penetration test is to mimic the activities of an actual assault. An employee or someone with initial access to the system is carrying out the assault. The term “Advanced Persistent Threat” (APT) attack is frequently used to describe this approach.
Furthermore, an internal pentest is not just for APT testing. You may want to conduct an internal pen test for a variety of additional causes. You should be ready for them to take business information with them, for instance, if a worker departs the organization or if you have a malevolent insider.
The idea is to identify any security holes in your system before an intruder does, allowing you time to devise a solution before you are affected.
Red and blue teams are internal groups that exist in many businesses. Both software engineers and cybersecurity experts might be a part of these groups.
The Blue Team will watch over the network and defend it from threats while the Red Team looks for security holes and vulnerabilities in it. Collectively, the two teams will seek to strengthen the network and increase assault security.
Depending on whether the company selects internal or external penetration testing, the precise objectives, technique, circumstances, and objectives may vary considerably.
The goal of external pen testing is to mimic how an external user without the right access and privileges could take advantage of exposed security holes in the internal network. In essence, the tester takes on the role of a malevolent intruder or criminal who might attempt to attack the company.
Determining how a malicious attacker with inside authority could attack the network’s weaknesses is the goal of internal pen testing. Additionally, it seeks to ascertain what details might actually be revealed to this insider.
It’s typically better to carry out both internal and external pen tests to fully identify network security flaws and improve the corporate overall security.
Red teams and blue teams: what are they?
In the field of IT security, the red team and blue team are frequently combined, yet they have quite different roles to play. Let’s get a thorough understanding of both sides.
The Red Team.
During penetration testing, the red team evaluates the cybersecurity’s susceptibility. In a procedure called penetration testing, examiners are given a target to breach through hacking.
Red teaming is the practice of employing an external attack to assess your company’s capacity for assault detection and mitigation. To test how a company would respond in actual scenarios, it is necessary to pose an external threat.
To evaluate the efficacy of cyber security measures, this concept is utilized. The crew is made up of skilled cybercriminals who were engaged by the company to perform cybersecurity testing. Without the IT or cyber security group’s knowledge, this is accomplished.
The objective is to breach security mechanisms and then record them. Then, any flaws that have been discovered are fixed using this specification.
The Blue Team.
People in charge of a company’s or asset’s security make up the blue team. The task of defending against external attacks falls to the blue team. Together, they form the red team.
In addition, the blue team is in charge of developing data security rules and practices, authorizing red team actions, and evaluating vulnerabilities. Additionally, they guarantee that the firm responds to risks appropriately.
Benefits of internal testing
Most firms today are strengthening their security against external threats, but often overlook the fact that 49% of cyberattacks originate internally.
Users don’t anticipate the individuals they trust to damage them, making an internal breach considerably more destructive than an external danger. Internal penetration testing is growing in popularity because of this.
The goal of internal penetration testing is to simulate an insider attack. It entails searching for security flaws in the network system, examining access restrictions within the framework, and assessing the security safeguards of both databases and apps.
One of the best methods to safeguard your business from the hazards posed by cybercrime is pen testing. Due to this, the technique is becoming more and more common, and some regulatory guidelines, like PCI-DSS or HIPAA, mandate some variation of it.
Yet, the majority of individuals immediately conjure up external penetration testing when they hear the term “pentest.”
It’s a widely held belief that external pen testing is more beneficial and significant than internal pen testing. This might be due to the increased usage of external pen testing. Internal pen testing, therefore, has special advantages that external tests are unable to deliver.
Internal pen testing is more efficient and successful in revealing information about internal systems and computer security because it starts from within.
Internal penetration testing can benefit your company greatly in several ways, including:
- Identify internal weaknesses
- To identify internal or insider threats
- Comprehensive & thorough examination
- Save money by avoiding data breaches.
- Assists in obtaining compliance
Internal Penetration Testing Procedure
-
Data Gathering
The initial step in penetration testing is data gathering, which involves gathering as much data as possible about the target assets or systems to conduct more penetration tests.
To utilize this data in the second stage of pen testing, this phase seeks to learn as much as it can about the targeted system or network.
The collection of data stage of penetration testing is crucial. If the data collecting is not done properly, data loss may occur, necessitating another round of pen testing on the part of the tester.
-
The Research Phase
The Penetration Tester employs the data acquired during reconnaissance to find flaws in the target during the discovery process. Different automation technologies are used by penetration testers to carry out automated scans.
Any further assaults will be built upon the knowledge collected during the reconnaissance phase, which also serves as the prelude to the discovery phase.
-
Extraction
Exploitation is the third stage of the hacking procedure. Any weaknesses that were initially found throughout the reconnaissance stage are used at this point by the attacker.
Accessing the target network is the aim of this stage. If the attacker can enter the target server, they can then take ownership of it and manipulate it to serve their needs.
-
Reporting
The reporting stage of pen testing is a crucial stage that aids in your understanding of the safety status of your system.
The report is often delivered to the corporation’s administration or IT division. Its major objective is to assist the organization (or the IT team) in making the best choices for fixing the safety issues found throughout the pen testing, enhancing general asset safety, and strengthening the organization’s cyber security postures.
3 typical internal penetration testing techniques
Given that internal penetration testing immediately affects your company, it’s crucial to adhere to industry norms.
Although you can add your methods and processes on top of regulatory requirements, be careful not to wander too far from the components that originally made the rule!
Here are the most popular internal pentest techniques:
- Penetration Testing Guide by OWASP
- PCI Penetration Testing
- NIST 800-115
Which internal networks ought to be examined?
Rarely does a hacker successfully acquire entry by specifically aiming for a vulnerable item. This makes sense since these delicate resources are usually the ones that are best preserved. Hackers frequently acquire initial entry by focusing on services and networks that the company perceives as being of low importance. Security is frequently weaker, giving the hacker a foothold in the system. The hacker moves and raises from this point until they have accumulated the necessary rights to get entry to the important resource. The complete ecosystem might be included in a smaller company. The indicative ranges chosen by a bigger company often include servers, terminals, networks, voice, and other resources. This enables the tester to investigate controls throughout the business and the interactions between surroundings elements.
