A Comprehensive Guide to Internal Penetration Testing in 2022

Businesses are concerned about data security these days as they try to avoid becoming the next victim of cybercrime. Hackers are continuously on the lookout for flaws that leave firms vulnerable to attacks in an increasingly remote and networked world.

Most businesses have policies and security procedures in place to prevent data breaches by now, but not all of them put their data security to the test. Penetration testing is used to solve this problem.

Internal Penetration Testing:

A complete security examination of the company’s internal systems is performed during an internal penetration test. This evaluation involves vulnerability scans to determine how far an experienced attacker may progress across your network and gain access to your data after gaining first internal access.

If a penetration tester acquires access to your network as part of an external penetration test, they will use that access to gather data, try to elevate privileges, and spread their access to other internal assets and applications.

Alternatively, the pen testing team can ask the client to connect a device directly to the internal network, eliminating the requirement for external testing and allowing them to focus solely on internal tests. This gadget is set up to provide dependable remote connections in order to finish the testing.

During an internal penetration test, the tester will gather information before attempting all known exploits to determine how the security measures respond to prospective assaults and breaches. Finding weaknesses that allow them to acquire admin control of a domain will be one of their key methods.

Internal penetration Testing methodology:

1:- INITIAL SCOPING & OBJECTIVES

Our internal network penetration testing experts work with you to define the assets in scope covering primary security concerns and any regulatory requirements.

Specific assessments defined against certain targets are defined under ‘white box’, ‘black box’, or ‘grey box’ methodologies to define internal network test cases before starting the assessment.


2:- LATERAL MOVEMENT & EXPLOITATION

An initial foothold is gained by exploiting weaknesses identified in the previous phase. Privilege escalation attempts and lateral movement actions are carried out to infiltrate and gain access to the network(s). Further vulnerabilities are exploited in a safe manner to measure the extent of exploitation, leading up to domain administrator account compromise.


3:- RECONNAISSANCE & INTELLIGENCE GATHERING

The reconnaissance phase has a single goal: to gather and analyse data in order to give valuable information for other stages.

Unless it’s a red team pentesting where personnel is in focus, intelligence collection is mainly infrastructure-related (e.g., network layouts, domains, servers, infrastructure data).


4:- DATA ANALYSIS & REPORTING

This comprises analyzing the test results, assessing the risk impact, and determining the likelihood of an attack before recommending action plans to mitigate the identified risks.

All of our reports include accompanying raw data for both business and technical audiences, as well as mitigation techniques at the strategic and tactical levels to assist customer security teams.


5:- ACTIVE SCANNING & VULNERABILITY ANALYSIS

Using manual approaches and penetration testing tools, our cyber security experts identify security weaknesses and prepare an attack layout to target vulnerable systems. It includes identifying open ports, and services, identifying relevant network interface web applications, and any vulnerabilities that could be exploited.


6:- DEBRIEF & SUPPORT

Our engagement process includes delivering a free-of-charge debrief to management and technical teams. This session involves helping to prepare a remediation plan based on the identified vulnerabilities and Q&A to ensure that customer contacts are up to date.Detox Technologies provides a remediation consultancy where we define and execute the risk mitigation plan.

Benefits of Internal Penetration Testing

1:- Measure an insider attacker’s extent for exploitation

2:- Assess an accurate picture of security controls

3:- Determine in-depth third-party/partner access to resources

4:- Assess strategic issues such as data exfiltration, leaks & misconfigurations

5:- Demonstrate cyber security commitment

6:- Helps shape IT strategy & investments
