A crucial component of solid cyber security is penetration testing, otherwise known as pen testing or ethical hacking. Essentially, penetration testing is a methodical process of scrutinising an organisation's IT system, network or web application to spot potential vulnerabilities a hacker could exploit. 

In this blog we look at the five stages of penetration testing: Reconnaissance, Scanning, Vulnerability Assessment, Exploitation, and Reporting 


The first stage, Reconnaissance, is the foundation of the entire process. In this phase, the tester embarks on an intelligence-gathering mission about the target system. The collection might encompass a variety of data, including information about IP addresses, domain details, network services, mail servers, and network topology. 

This proactive intelligence gathering provides invaluable insights, helping to sketch a detailed blueprint of the target's environment. Armed with this information, the tester can devise an informed testing strategy that can effectively probe for vulnerabilities, setting the stage for the subsequent phases of the penetration testing process.


Next comes the Scanning stage. This phase involves an in-depth technical review of the target system. Automated tools like vulnerability scanners, network mappers, and others are used to understand how the target system responds to various intrusions. 

Scanning enables testers to determine how the target application behaves under different conditions and to identify potential weak points that could be exploited. It maps out the system's digital terrain, enabling the tester to spot possible points of ingress that an attacker might use.

Vulnerability Assessment

Once the target system has been thoroughly scanned, the process proceeds to the Vulnerability Assessment stage. This phase is a careful analysis of the target system to identify potential points of exploitation. 

Using a combination of automated tools and manual methodologies, the tester scrutinises the security of the systems, identifying any potential loopholes. This meticulous assessment ensures a complete understanding of the system’s security posture, flagging potential vulnerabilities that could be exploited by cybercriminals. 


Once the Vulnerability Assessment is complete, the next stage is Exploitation. In this critical phase, the tester attempts to capitalise on the vulnerabilities discovered. The aim isn't to cause damage but to ascertain the depth of the vulnerability and assess the potential damage it could cause. 

Exploitation might involve data breaches, service disruption, or unauthorized access to sensitive information. This stage needs to be carefully controlled and monitored, to ensure that the system isn't accidentally damaged during the process. It’s a delicate balancing act between pushing the boundaries and maintaining the integrity of the system.


The final stage is Reporting, where the tester compiles a comprehensive report detailing their findings. This includes the vulnerabilities discovered, data exploited, and the success of the simulated breach. 

But the report is not just a list of issues. It also offers recommendations for addressing the vulnerabilities, including software patches, configuration changes, and improved security policies. The report serves as a roadmap, guiding the organization towards a more secure IT infrastructure.
