Internal Penetration Testing

back to our services...

An internal penetration test focusing on authenticated vulnerability scanning, network attacks, and misconfigurations aims to assess the security posture of an organization from the perspective of an insider or someone with authorized access.

Internal Penetration Testing
This type of penetration test is crucial for identifying and addressing vulnerabilities that could be exploited by an attacker with insider access, helping to strengthen the overall security posture of the organization.

This type of penetration test typically includes:

Authenticated Vulnerability Scanning:

  • Identifying vulnerabilities in systems, applications, and network devices using authenticated scans.
  • Assessing patch levels and security configurations in operating systems and software, across both servers and s sample of end user devices.

Network Attacks:

  • Testing for vulnerabilities in network protocols and services.
  • Conducting man-in-the-middle (MITM) attacks to evaluate data exposure risk. These typically involve ARP poisoning, DNS and IPv6 attacks.

Misconfiguration Analysis:

  • Reviewing network device configurations (routers, switches) for security weaknesses.
  • Examining server and application configurations for security lapses.
  • Identifying improperly configured permissions and access controls across accessible systems and file shares.
  • Attempt lateral movement using re-used credentials.

Access Controls and Privilege Escalation:

  • Assessing the strength and effectiveness of access control mechanisms.
  • Attempting to escalate privileges to gain unauthorized access to sensitive data or systems.

Lateral movement:

  • Moving around the environment using acquired or provided credentials.
  • Identifying opportunities to gain access to sensitive data and systems.

Internal Data Exposure and Leakage:

  • Identifying sensitive data that is inadequately protected or exposed.
  • Testing for data leakage scenarios within the internal network.

Segmentation Testing:

  • Evaluating network segmentation and its effectiveness in isolating critical systems.
  • Testing for unauthorized access across different network segments.

Wireless Network Security (Optional):

  • Assessing the security of internal wireless networks.
  • Testing for vulnerabilities like weak encryption and rogue access points.

Firewall Configuration Review:

  • Reviewing and analysing firewall configurations.
  • Checking for proper settings and rules that control both ingress (incoming traffic) and egress (outgoing traffic) to prevent unauthorized access and data exfiltration.

We initially reached out to Punk Security to help us out with our hosting architecture and were impressed with their breadth of knowledge.

With their expertise we were able to implement additional controls into AWS and successfully scale our systems. When we needed to gain more performance insights, their engineers configured our datadog platform end to end.

We’ve found that they really take the time to understand our problem and then put forward a great solution.



Services: Trusted Security Partner, Managed Incident Response

Our internal IT team were in need of expert consultancy to help us strengthen our cybersecurity measures and protect our sensitive data.

We engaged the services of Punk Security and were thoroughly impressed with the level of professionalism and knowledge they brought to the table.

The team was able to provide valuable insights and recommendations, and their guidance helped us implement effective security protocols that have greatly enhanced our overall security posture.



Services: Incident Response, Cloud Engineering support

We originally sought Punk’s services to support us with a potential cyber-attack. The team responded immediately, out of hours, and calmly and professionally walked us through the necessary steps to determine that our environment hadn’t been compromised.

Since then, we have engaged Punk to carry out a third party audit of our cloud environment and a gap analysis against the Cyber Essentials and ISO270001 criteria. The team provided a thorough report with recommendations and are now working with us to improve our processes and systems.

I feel assured that we are walking towards best practice security operations.

Having attended a live hack demo held at C4DI we approached Punk Security to help sure-up our cyber security and DevOps processes. Punk not only completed this audit but passed on valuable gained knowledge to our team to broaden their skills and insight in this area.

We have since continued to work in partnership with Punk to implement a WAF and frequently consult their expertise in DevOps in relation to our application so we can all learn and grow in a collaborative way.

Punk are approachable, knowledgeable and also adept at explaining in layman’s terms for the less technical! We look forward to continuing our fruitful working relationship.



Services: DevSecOps training

Our team at Illumio recently participated in a custom CTF event hosted by Punk Security, and it was a great experience! The CTF was not only challenging but also immensely educational, especially in the realm of cloud security principles.

The challenges presented during the CTF were designed to cover a broad spectrum of cloud security topics. This approach allowed our team to dive deep into practical scenarios that tested our skills and pushed us to explore new strategies and technologies. The balance between difficulty and learning outcomes was perfectly struck, ensuring that each team member, regardless of their prior level of expertise, found the event to be rewarding.

Punk Security were happy to perform external scans pro bono due to our status as an NGO.

The team also spent meeting time on two separate occasions to discuss our requirements and provide advice without any commitment or expectation. I’ll certainly be coming to Punk Security again in future should we need further security services



Services: DevSecOps training

Punk Security provided exceptional DevSecOps training for our engineers here at Sage and delivered an outstanding talk at our Securing Sage Summit.

Their expertise and knowledge were evident throughout the sessions.

Not only were they efficient and great to work with, but their presentation was also the highest rated session of the entire event. We highly recommend Punk Security for any security-related needs.
