The internet world is still growing. People are spending more time (and money) online than ever before, and this trend does not appear to be stopping anytime soon. Individuals have fully embraced life online, propelled by convenience and given some extra propulsion by a pandemic that reduced people’s capacity to make real-world connections.

Technology is evolving at a rapid rate, as are the dangers that attack it. Cybersecurity has never been more important, and one of the cornerstones of a solid security plan is penetration testing. In this post, we’ll look at penetration testing, its importance, and how it may help your IT infrastructure.

What is Penetration Testing?

Penetration testing is a technique for simulating a cyberattack in order to find flaws in your computer system, network, or online applications. It’s referred to as an ethical hack because it’s utilized to improve your cybersecurity.

A penetration test, or pen test as a service, should not be confused with a vulnerability assessment, which assesses possible vulnerabilities in a network and makes suggestions to mitigate these risks. Because penetration testing simulates a cyberattack, it is more intrusive.

Pen testing aims to assess the amount of risk associated with vulnerabilities in IT infrastructure. Companies invest extensively in their development and engineering teams to establish their digital infrastructure in today’s environment. However, they frequently fail to perform all of the essential measures to secure and safeguard their systems after deployment.

Then, when an attack happens on their networks, businesses react by forming an incident response team. This is to analyze their systems, rather than tackling it proactively with pen testing and security scanners. Companies may close the loop on this cycle by implementing a competent pen testing program.

Companies follow particular methodologies to perform penetration testing known as, black box, white box, and gray box testing:

  • Black Box Testing: Here the tester is given only the bare minimum of information, such as the firm name. A tester will be able to imitate an attacker who is unfamiliar with the company. When this high-level knowledge is supplied upfront, time might be saved testing for possible vulnerabilities.
  • Gray Box Testing: Here the tester is given more information, such as specific hosts or networks to target. This can give a solid picture of what a focused assault would look like without forcing the tester to spend a lot of time gathering data.
  • White Box Testing: This form of testing entails giving the tester various internal documentation, configuration blueprints, and so on. The tester will be able to devote more time to exploiting vulnerabilities rather than host enumeration and vulnerability scanning.

The Perks of Performing Penetration Testing: The Significance

Organizations press developers to create the product they commissioned as soon as possible so that it may be marketed and income generated. As a result, the hurriedly developed code is riddled with security flaws and defects that may be easily exploited for malicious purposes.

The same is true for infrastructure, which is frequently implemented in haste since businesses can’t wait and ROI is expected quickly. Penetration testing services help with these hassles with their numerous benefits such as:

It Exposes Vulnerabilities

A pen test allows businesses to identify where their vulnerabilities exist and how these vulnerabilities might be exploited. This test is performed in a secure environment where the pen tester is working with your organization rather than against it.

It’s similar to carrying out a test of your business continuity plan. You believe you’ve got everything covered, but even the best plan may be revealed to have a huge hole when a question or problem that no one has ever considered before is posed.

Gives Perspectives on Digital Infrastructure

Pen testing aids in the development of a deeper knowledge of your digital systems. This improves comprehension of how to prioritize risks and devise methods to mitigate the most harmful ones. As a result, alignment between repair and continuing corporate goals and objectives is possible.

Furthermore, firms might gain just by mapping out their digital infrastructure. Outlining your digital assets, a critical step in initiating a pen test, sheds information on how systems interact with sensitive data. This allows resources to be directed toward the most critical components and the development of appropriate security.

It Develops Customer Trust

With fresh hacks being disclosed nearly daily in the press, the importance of cybersecurity penetration testing should be obvious from a public relations aspect. When firms demonstrate that they have proactively checked their networks for vulnerabilities, it helps customer service.

Pentest might assist in convincing clients that they are in good hands with your organization. More importantly, avoiding the shame of a public hack improves consumer relations significantly. Investing in a strong penetration testing service provider can help prevent trust loss.

It Reduce the Number of Errors 

Penetration testing reports can also help developers make fewer mistakes. When developers understand how a hostile entity launched an assault against an application, operating system, or other software they helped create, they will become more committed to learning more about security and will be less likely to make similar mistakes in the future.

It should also be highlighted that penetration testing is especially critical if your company:

  • Has recently upgraded or changed its IT infrastructure or applications significantly,
  • Has just moved to a new location,
  • Have security patches, or
  • Alterations in End-user policies.

It Assists with Regulatory Compliance 

Many standards and laws are in place to secure data across many businesses. If you operate in business, you are probably bound by the PCI DSS standard. HIPAA standards must be followed if you operate in the healthcare industry.

Whatever standard your sector utilizes to safeguard consumers or clients, penetration testing providers may ensure that your company meets these standards. Industry compliance is critical because it helps you avoid regulatory penalties, potential litigation, and a variety of other difficulties that can affect your organization.

What are the Types of Penetration Testing?

A penetration test is most often done externally by companies to mimic various attack paths. A penetration tester may or may not have previous knowledge of the environment and systems they’re seeking to break, depending on the aims of each test. Here are some of the top types of penetration tests:

    Web App Penetration Testing

    Web application penetration testing performs on web apps to identify security flaws or vulnerabilities in web-based applications. It employs several penetration techniques and assaults in order to get access to the web application itself. An online penetration test’s standard scope covers web-based applications, browsers, and associated components.

      IoT Penetration Testing

      IoT penetration testing searches for security flaws in linked ecosystems, such as flaws in hardware, embedded software, communication protocols, servers, and IoT-related online and mobile apps. Some devices, for example, may necessitate data dumping via electronic components, firmware analysis, or signal collection and analysis.

        Mobile App Penetration Testing

        Mobile application penetration testing is done on mobile applications (but not mobile APIs or servers), and it includes both static and dynamic analysis:

        • Static analysis gathers source code and metadata and then reverse engineers it to find flaws in application code.
        • While the program is operating on a device or server, dynamic analysis detects application vulnerabilities.

        External Network Penetration Testing

          External network penetration testing examines your present richness of publicly available information or assets. The assessment team seeks to acquire access to data via external-facing assets like as corporate emails, cloud-based apps, and websites by exploiting vulnerabilities discovered when screening your organization’s public information.

            Cloud Penetration Testing 

            Cloud penetration testing intends to examine a cloud system’s strengths and vulnerabilities in order to enhance its overall security posture. Cloud penetration testing aids in the identification of risks, weaknesses, and gaps. The consequences of vulnerable vulnerabilities. Determine how to make use of any access gained through exploitation.

            What is the Process of Penetration Testing?

            Organizations often penetration testing companies to test their infrastructure to find vulnerabilities. These service providers have a specific process of conducting penetration tests for the application or network provided. Here’s a glance at the whole process:

                                    What is the primary purpose of penetration testing?

                                    Pen testing (or penetration testing) is a security exercise in which a cyber-security specialist seeks to discover and exploit flaws in a computer system. The goal of this simulated attack is to find any weak points in a system’s security that attackers may exploit.

                                      How does penetration testing contribute to overall cybersecurity efforts? 

                                      Pen testing assesses a company’s capacity to defend its networks, apps, endpoints, and users against external or internal efforts to overcome security rules and obtain unauthorized or privileged access to protected assets.

                                        What types of vulnerabilities can penetration testing uncover? 

                                        Some of the most prevalent vulnerabilities discovered during external infrastructure penetration testing include Password attacks, cross-site scripting, application-level attacks, misconfigured security, and firewall devices.

                                          How often should organizations conduct penetration testing?

                                          Penetration testing should be conducted on a regular (at least once a year) basis to guarantee more consistent IT and network security management by disclosing how newly found threats (0-days, 1-days) or growing vulnerabilities might be exploited by malevolent hackers.

                                            Can penetration testing be automated, or does it require manual intervention?

                                            Manual and automated penetration testing are the two basic approaches used in the process. Each technique has different advantages and disadvantages; thus, security experts must establish a balance between the two in order to conduct full and successful security evaluations.
