Why is Penetration Testing important for your Organisation?

Organisations of all sizes face increasing cyber threats, making proactive security measures more critical than ever. These threats are not foreign states as often misconstrued, but more often due to our lack of proactive approach towards misconfiguration, vulnerabilities due to lack of timely patching, secure hardening practices or insecure coding practices. This is why we are exploring the importance of penetration testing with ever-increasing threat landscape.

Penetration testing or ethical hacking is a cornerstone of any robust cybersecurity strategy. It offers a cost-effective way to identify and mitigate vulnerabilities. Regular penetration tests, ideally conducted at least annually, are essential for maintaining a strong and secure IT infrastructure.

What is Penetration Testing?

Penetration testing, often called pen testing, is a simulated cyberattack conducted against your Organisation’s computer systems, networks, and applications.

Ethical hackers, also known as pen testers, meticulously probe these systems, attempting to exploit vulnerabilities and gain unauthorised access. These vulnerabilities range from design and injection flaws to configuration errors and software bugs. Pen tests can be tailored to target specific applications, individual IP addresses, or even the Organisation’s entire network.

The Pen Testing Process

A typical penetration test involves several key phases:

1. Planning and Scoping: This initial phase defines the objectives of the test, determines the scope of the assessment (i.e., which systems and applications will be targeted), and establishes the rules of engagement.
2. Reconnaissance: The testing team gathers information about the target environment (in case of external testing or internal testing) or gains information through unauthenticated sessions (web app pentesting), including network topology, software versions, and publicly available information.
3. Vulnerability Scanning: Automated tools identify potential vulnerabilities in the target systems.
4. Exploitation: A penetration tester attempts to exploit the identified vulnerabilities to gain unauthorised access (though approved through authorisation forms) outside the current user privileges.
5. Post-Exploitation: Once access is gained, further attempts are carried out to escalate privileges or move laterally within the network until the domain administrator, in case of internal testing or highest level privileges, is achieved to demonstrate the potential impact of a successful attack.
6. Reporting: A comprehensive pentest report detailing the identified security vulnerabilities, the potential impact of exploitation, and recommendations for remediation is generated.

These penetration testing reports serve as crucial documents detailing the tests’ findings, including vulnerabilities discovered, targets, and recommendations for remediation. Penetration testing reports are valuable resources for developers to learn from their mistakes and reduce future errors.

Types of Penetration Tests

Penetration tests can be categorised based on various factors, including the scope of the assessment, the level of knowledge provided to the pen testers, and the target environment. These targeted testing types are:

• Black Box Testing: The pen testers have minimal knowledge of the target environment, simulating a real-world attack where the attacker has limited prior information. Double blind testing is also part of black box form of pentesting.
• Grey Box Testing: A penetration tester has some knowledge of the target environment, such as network diagrams or access credentials to conduct the assessment and gain access into authenticated areas.
• White Box Testing: The pen testers have extensive knowledge of the target environment, including documentation, source code and computer system configurations.
• Internal Testing: Conducted within the Organisation’s internal network to identify internal network and active directory security risks that could be exploited by insiders or attackers who have already gained access.
• External Testing: Targets internet-facing systems and IT infrastructure to identify weaknesses that a cyber criminal could exploit.
• Network Penetration Testing evaluates a network’s defences and identifies potential vulnerabilities through specialized tools. It is distinct from vulnerability scanning because it aims to assess and improve network security by simulating real-world attacks.

Importance of Penetration Testing

Penetration testing is not merely a technical exercise; it’s a crucial component of a holistic security strategy. It provides a clear and objective assessment of your Organisation’s security posture, highlighting weaknesses that might remain hidden.

The average to a major data breach cost can exceed $3 million to hundreds of millions for organizations. By proactively identifying weaknesses and addressing these vulnerabilities regularly, you can significantly reduce the risk of a successful cyberattack by staying on top of security threats.

Penetration testing also helps you validate the effectiveness of your existing security controls and identify areas where further investment is needed. It provides valuable data for making informed decisions about data security investments and resource allocation.
