Penetration Testing

What is Penetration Testing?

Penetration testing, also known as “pen testing,” is a critical cybersecurity practice whereby experts, called “ethical hackers,” intentionally try to break into a computer system, network, or application. They do this to discover security flaws and weaknesses that could allow bad actors to get in. The result of a penetration test is a detailed report containing the vulnerabilities discovered and exploited, and actionable recommendations for remediation.

The Cybersecurity Threat Landscape

The cybersecurity threat landscape is constantly evolving, with new challenges arising as technology advances. Currently, organizations must contend with a plethora of threats, including ransomware, software supply chain attacks, and well-organized and funded nation-state attacks. During the COVID19 pandemic, organizations began shifting to teleworking which widened the attack surface. Although the pandemic has ended, many organizations are still dealing with the challenges of securing remote access and cloud technologies. Cybercriminals are seizing the opportunity to exploit these vulnerabilities, making it crucial for organizations to adopt robust security solutions.

How Can Penetration Testing Benefit Your Business?

Pen testing plays a crucial role in an organization’s security strategy by:

01

Penetration testers use their skills and experience to reveal security vulnerabilities that automated tools might miss, offering a detailed view of potential entry points that cyber adversaries would likely exploit.

02

By mimicking the mindset and actions of malicious actors, pen testing offers insights into how an actual cyber incursion could occur, allowing organizations to understand and improve their defensive strategies.

03

The results of a pen test can help organizations to prioritize and mitigate identified vulnerabilities, thereby strengthening their overall security resiliency.

04

Organizations conduct regular pen testing to help them meet regulatory compliance and industry standards, which often mandate periodic security assessments.

05

By uncovering potential attack pathways, the findings of penetration tests can inform incident response teams on how to test and improve their incident response plans, strengthening their preparedness for effectively handling security breaches.

06

Penetration testing can also be a powerful training tool by increasing awareness among employees about the significance of security and the potential consequences of security breaches.

How Is Penetration Testing Done?

Penetration testing is a cyclical process formed of several phases. At Byte Defense Solutions, we employ various methodologies such as the Penetration Testing Execution Standard (PTES), the Open Web Application Security Project (OWASP), and NIST 800-115 testing methodology. In a nutshell, this is how it’s done:

Penetration Testing Process

  • Pre-Engagement
  • Information Gathering
  • Vulnerability Assessment
  • Exploitation
  • Post-exploitation
  • Reporting
This initial phase sets the stage for the penetration test, involving a series of inquiries and formal agreements. Clients specify their testing requirements and objectives. Key elements include the scoping questionnaire, pre-engagement meeting, and kick-off meeting.
In this essential phase, our team thoroughly collects data on the company’s structure, staff, and systems. Information gathering is a continuous part of the entire penetration testing cycle, involving open-source intelligence, and enumeration of infrastructure, services, and hosts, through both passive and active scanning methods.
In this phase, we scrutinize the gathered data to pinpoint vulnerabilities within network or system components. We consult the National Vulnerability Database (NVD) and the Common Vulnerability and Exposure (CVE) records to assess the severity of these vulnerabilities using the Common Vulnerability Scoring System (CVSS) ratings.
In this phase, our team leverages accumulated insights to exploit identified vulnerabilities, emulating tactics of attackers to penetrate the target system. We meticulously strategize each step to ensure efficacy and minimize potential negative impacts.
After securing a foothold, our team conducts post-exploitation tasks, revisiting Information Gathering to extract sensitive data from an “insider” view. We aim to maintain access, elevate privileges, extract data, and pivot to other systems, which, if successful, restarts the penetration testing process from Information Gathering.
In the reporting phase, our pen testers compile a report detailing the test outcomes, assessing the business impact of vulnerabilities, and offering remediation guidance to enhance your security stance.

Summary

As the cybersecurity threat landscape evolves and becomes more complex, penetration testing emerges as an invaluable tool for organizations to proactively find and remediate security vulnerabilities, enhance the protection of their digital assets, and stay ahead of cyber threats.
