What is internal penetration testing?

Internal penetration testing in New Zealand simulates an internal attacker such as an employee or contractor who has access to your internal network or external intruders who have breached perimeter defences.

This is done by finding the attack path that a potential internal threat actor could use to gain access to sensitive data from your organisation’s internal network. This includes file servers, workstations, and applications. As well as finding how a malicious party can exploit internal systems and network weaknesses, internal penetration testing can find threats that emanate from accidental errors made by staff that can lead to data exfiltration or other significant issues.

During an internal penetration test, an experienced tester will be given some access to your internal network. This is typically the same sort of access an ordinary employee has. The tester will attempt to escalate the level of privilege that account has with the intent of accessing data or systems that the account ought not be able to access. Or, the tester could use their escalated privilege to compromise network equipment in order to launch a larger and more damaging attack.


Why Internal Penetration Testing Matters to Your Organisation?

While significant attention is given to detecting and mitigating the risks associated with external attackers, internal penetration testing detects the risks of an internal actor with access to your network.

Internal pen testing gives your organisation an understanding of how an internal attacker could compromise your internal network and provide real insight into the potential damage and business risk an attacker could inflict.

As well as detecting technical issues, a penetration test can detect weaknesses in policies and procedures. This can include giving users unnecessarily escalated privileges, weak processes for assigning access to systems or poorly defined system access roles.

An internal penetration test ensures that your internal security posture is robust and that internal weaknesses are recognised and remediated.


How Can Tesserent Help New Zealand Organisations?

Tesserent a highly regarded cybersecurity company, will engage their internal penetration testing team to conduct internal testing for Australian and New Zealand organisations for many years across a wide variety of different industries. This has allowed companies across the ANZ region to enhance protection of their business intelligence, data and IT systems, brand and reputation.

Tesserent’s experts start internal penetration testing with reconnaissance to understand the structure of the internal network and how information is accessed and used. Internal penetration testing can examine the operation and configuration of a broad range of systems including Wi-Fi networks, end point devices, firewalls and applications. This information is used for vulnerability detection and then moves to actively exploiting those vulnerabilities.

At the conclusion of the internal penetration testing engagement, Tesserent prepares a comprehensive report outlining the security exposures of your internal network, including high impact recommendations and root causes. The report includes an action plan detailing how to resolve issues so your organisation can strengthen its security posture and reduce risks.
