Internal infrastructure penetration testing

It takes the average company 280 days to realise an attacker is in their network.

Do you know how far an attacker could get within your environment in that time?

Internal infrastructure penetration testing is an integral part of any organisation’s security strategy, assessing how misconfigurations or vulnerabilities within your internal network, both on-premise and in the cloud, could be exploited by an attacker who has insider access to your environment.

Working to an agreed scope, our consultants attempt to compromise hosts, including Active Directory, Windows & Linux servers, and database servers, using non-destructive attack methods. Where possible, this may lead to the exfiltration of data.

The outcome of an internal infrastructure penetration test is a list of vulnerabilities within the specified hosts and a solid remediation plan for mitigating the risks.

Our internal infrastructure penetration testing aims to highlight vulnerabilities and misconfigurations of systems, which can lead to privilege escalation, theft of data, and even the ability to gain a persistent foothold within the network.

Although methods used will vary for each engagement, dependent on the services in use and the client’s appetite for risk, we follow a similar methodology in each project. Initially, our consultants run vulnerability scans to quickly highlight potential risks. They then manually investigate issues, which leads to the exploitation of vulnerabilities and the eventual compromise of the host or system where possible.

As part of the engagement, our consultants provide risk ratings for each vulnerability based on the ease of exploitation and the potential impact should the exploit be used. This helps you to prioritise your remediation efforts, and manage your risks accordingly.

Given that every environment is constructed slightly differently, all of our internal infrastructure penetration tests are tailored to your specific requirements.

Following the delivery of the report, we recommend a follow-up call to run through the findings and ensure that remediation advice is clear. This also allows your team to ask any further questions and clarify any areas of uncertainty.

Analysis and potential exploitation

This testing is designed to assess security posture against best practices and attempts are made, where safe and permitted, to exploit any vulnerabilities discovered.

This may involve escalating privileges if possible, accessing key systems and ultimately exfiltrating confidential data if practical.

Is bringing your own device to work a bad idea?

As ‘Bring Your Own Device’ or BYOD rises in popularity, with more than two-thirds of us using a personal device at work, it’s important for businesses to understand the security risk that this can pose.


What is attack path management?

In a world where identities are the new security perimeter, compromising identity platforms like AD and AAD provides the greatest payoff for attackers, ultimately giving them control of all users, systems and data within the organisation.


.ZIP domain registration: A risky gateway to nefarious outcomes

In the ever-evolving world of cybersecurity, understanding emerging threats is critical to maintaining a robust defence. One trend currently attracting attention is the registration of .ZIP domains.
