A penetration test, also referred to as a pentest, is a security analysis that mimics the harmful actions of actual hackers to find security flaws in the software or systems used by your company. A pen test’s purpose is to discover the weaknesses in your company’s IT networks, how they may be abused, and what would happen to the company if a hacker were to succeed.
External penetration testing is what it’s termed when it’s carried out by a third-party security team. External penetration testing can be extremely thorough, including human scrutiny, source code analysis, etc. Alternatively, depending on the needs, a company’s system and network may only be focused on publicly visible resources.
Web applications, mobile applications, networks, network devices, and other types of software are frequently the targets of penetration testing.
What an External Network Penetration Test Is Used For
The exterior kind of penetration test might be the closest to a literal translation when considering what that term means.
An external network pen test is made to identify and take advantage of holes in hosts that can be reached via the Internet. Your pen test team takes on the role of a hacker on the public Internet and makes an effort to compromise any web-facing resources you may have by locating weaknesses and setting errors.
Your pen test team will try to break through where they can in order to obtain access to your underlying infrastructure or application using various approaches such as port scans, vulnerability scans, assessments of weak or basic setups, and manual efforts to exploit any vulnerabilities detected on all in-scope servers.
But that’s all there is to it. If a high-risk problem has been found, your pen test team should give you with a progress report that includes instructions to recreate the issue and accompanying images. There is no additional activity done to pivot further if they manage to acquire access to the company’s network. A list of findings that require correction is what’s left.
The difference between an internal penetration test to an external penetration test
External penetration testing
A specialized group of security researchers does external penetration testing independently. Security testing can be outsourced affordably. Our external penetration testing is excellent at simulating a hacker’s actions on the target system and provides a new viewpoint on the platform’s safety. Since it is an outside engagement, conducting it typically takes time. External penetration testing is required to meet a number of compliance requirements.
Internal penetration testing
Cybersecurity experts perform internal penetration testing. Maintaining a full-time security staff can be expensive and in-house security experts frequently find it difficult to view a network from a hacker’s point of view because they are familiar with its inner workings. Internal penetration testing can be conducted more often and with less advanced planning and is insufficient to meet regulatory standards.
Who Has the Most Need for External Penetration Testing?
For businesses to have a website or online app that is accessible to the public, external penetration testing is essential. Due to their direct online exposure and accessibility by anyone who has internet access, these technologies are frequently the most susceptible to attacks.
Thorough external penetration testing of these networks is required, particularly after any major upgrades or modifications. By doing this, you can make sure they won’t be a target for an assault and can keep providing their services unhindered.
There are five steps in an external penetration test.
Planning helps prevent chaos. You must adhere to a process in order to execute an effective and methodical external penetration test. External penetration testing can be broadly divided into the following five stages:
- Prior to date:
In order to prevent any incompatibilities, this is the stage where the tester and the client agree on the participation conditions, pentesting technique, test kinds, security goals, and results.
You (the customer) must be prepared with the following responses in order to get the most out of an external penetration test:
- Why do I need to run pentests?
- What am I hoping to accomplish with it?
- Do I require any extra tests?
- What strategy am I considering? gray box, white box, and black box
- What resources are essential to my business and should be given top priority
- Do I need to be certified, and so forth.
After concluding the transaction and accepting an NDA, you can start the penetration testing after everything is functioning as it should.
- Defining the breadth or reconnaissance
The process of determining the breadth involves identifying the resources (web pages, user management, APIs, networks, etc.) that will be subjected to the pentest. Additionally, at this point, both parties exchange essential information and access.
Cybersecurity experts and the company typically choose the kind of penetration test to run throughout this step.
For example, network penetration testing may be required if your company plans to test its network; web app pentesting may be required if you require to test your web application, and so on.
- Extraction
The most interesting and crucial aspect of penetration testing is abuse. This is where pentesters use a variety of cyberattacks to try and compromise your system.
Privilege elevation, XSS, SQL injection, and other cyberattacks are evaluated against your app or system. To expedite some scanning tasks throughout the test, pentesters employ a number of advanced technologies.
- Reporting and Correction
After the exam, the tester writes a thorough yet concise report detailing the results. The specifics of the weaknesses, the CVSS rating, the methods to replicate and patch them, etc., should all be included in a perfect penetration testing document. A penetration testing document should also provide a concise, understandable overview of the key findings that can be quickly read and examined.
Finally, remediation. The company has to address the reported weaknesses at this point. The expert will retest the delivered solutions if the weaknesses are fixed within the engagement’s duration. If the timeframe wasn’t met, a fresh contract would be necessary, and the rescan would cost more money.
- Re-Scan and Certification
The external penetration tester evaluates your industry standards and patches at the conclusion of their work. A pentest certificate will be issued to your organization by the security team/company if the flaws are successfully addressed.
External Penetration Testing Advantages
A complete study of systemic flaws and their effects is provided by external penetration testing, which offers an outsider’s perspective on the safety of your network.
The benefits of external network penetration testing are listed below.
Data protection
Both businesses and individuals have been extremely concerned about data breach. Pentesters replicate attacks that are most similar to the genuine event by acting like real-world cyber criminals. By doing so, it becomes feasible to identify information leak locations that can later be connected to stop further data intrusions.
Security Adherence
The external penetration testing list of requirements covers evaluating potential threats, offering insight into security priorities, and providing insights. It demonstrates how a hacker could jeopardize your systemic problems.
Additionally, it offers information on how to prioritize security spending according to actual risks. Furthermore, being aware of an attacker’s viewpoint may help one develop a strategy for dealing with serious hazards.
Cost-effectiveness
By outsourcing security analysis to security experts that use a tried-and-true technique, security compliance expenses can be much reduced as opposed to internal penetration testing, which requires you to retain a full tech staff of pen testers.
Assures the safety of your project
Your project is protected by penetration testing from risks like
- DDoS attacks
