ValueMentor’s Penetration Testing Services assist customers in improved risk mitigation

At ValueMentor, our CREST certified Security Analysts present companies with a detailed vulnerability report and recommendations for improvement in their security infrastructure. Network penetration testing enables IT departments to validate existing security controls and meet security compliance requirements while allowing managers to better prioritize investment for remediation efforts.

Types of Network Penetration Test

External Penetration Testing

This test shows what a hacker can see into the network and exploits the vulnerabilities seen over the internet. Here the threat is from an external network from the internet. This test is performed over the internet, bypassing the firewall.

Internal Penetration Testing

Internal Penetration test shows the risks that arise from within the network. This test is performed by connecting to the internal LAN and thereby trying to explore the vulnerabilities that exist.

Segmentation Testing

Segmentation testing segregates the less secure networks from more secure networks and ensuring that the communication between these networks is restricted.

Black Box Penetration Testing

This test is carried out with zero knowledge about the network. The tester is required to acquire knowledge using penetration testing tools or social engineering techniques. The publicly available information over the internet may be used by the penetration tester.

White Box Penetration Testing

This test is called complete knowledge testing. Testers are given full information about the target network. This information can be the host IP address, domains owned, applications used, network diagrams, security defenses like IPs or IDs in the network.

Gray Box Penetration Testing

The tester stimulates an inside employee. The tester is given an account on the internal network and standard access to the network. This test assesses internal threats from employees within the company.

Benefits of Penetration Testing

Criticality of Vulnerabilities

Proactive identification of the criticality of the vulnerabilities and false positives given by the automated scanners. This helps in prioritizing the remedy action, whether the vulnerability is to be patched immediately or not based on the criticality.

Regulatory Compliance

Penetration testing helps comply with the audit regulatory standards like PCI DSS, HIPAA and GLBA. This avoids the huge fines for non-compliance.

Cost of Compliance

A security breach may cost heavily to an organization. There may be a network downtime leading to a heavy business loss. Penetration testing helps in avoiding these financial falls by identifying and addressing the risks.

Why Network Penetration Testing

The IT infrastructure is becoming more complex and wider. The internal networks have been given access over the internet to the legitimate users along with the user credentials and the privilege level, outside the firewall, which increases the surface of attack. Such infrastructure needs to be assessed regularly for security threats.

Identification of what type of resources are exposed to the outer world, determining the security risk involved in it, detecting the possible types of attacks and preventing those attacks.

Network Penetration Testing Methodology

Network Penetration Testing Methodology

Information gathering & Network Discovery

We gather information such as Active Hosts, Active Services, Insecure Services, Fingerprinting the Operating System, Services and links and internet surfing related to this, etc.

Scanning and enumeration

This process involves port scanning, service detection, and OS fingerprints.

Gaining access

Gaining access involves vulnerability assessment and exploiting.

Remedial Action Identification

In this phase, our security analysts prepare the remedial actions for the threats and vulnerabilities discovered in the previous phases.

Reporting & Re-Testing

A detailed report of the findings, recommendations on remediation are submitted. On successful remediation, a retest is performed to validate the effectiveness of the fixes applied
