Network Vulnerability Assessment and Penetration Testing

Network security breaches are growing more regular and costly for businesses all around the world. 

Organizations must protect their networks and applications from cyberattacks and hacking threats. Individual firms can achieve this by implementing network security rules and performing an in-depth network vulnerability assessment and penetration testing is one of the important network security controls/practices.

Standards followed are:

How CBL can help?

CBL’s focus of the assessment is on the identification and exploitation of security weaknesses that could allow a remote attacker to gain unauthorized access to organizational data. The attacks are conducted with the level of access that a general Internet user would have along with elevated privileges where required. The assessment is conducted in accordance with the recommendations outlined in CIS Benchmarks and NIST with all tests and actions conducted under controlled conditions.

Network VA & PT Services

VA & PT Compliance

Various cybersecurity compliance require security testing of the network architecture. This includes network security concepts.

> DMZ Creation

> Network segmentation testing

> Firewall and core switch config

> Flat file exposure

> Security groups, IDS and IPS config

Network Security Testing

Network Security tests performed before launch or anytime after significant change. Ensure the network is resilient and secured. 

> Customised testing program 

> AWS and Azure networks 

> Identify network layer vulnerabilities

> Quick turn around times

> Compliance tool for maintenance

Periodic Security Testing

Periodic network security testing is required by various compliance programs. It is also a great way to keep your organization network defended. 

> Customised testing program 

> Test on premise and cloud networks

> Included in the dev-ops cycle 

> Solutions for fixing vulnerabilities

> Track your compliance 

Our Approach

CBL follows the following approach while performing network penetration testing.

1. Discovery

Aims at identifying all potential assets for investigation. The information gained through the discovery process creates a road map for the investigation module.

2. Analysis

Utilizes the list of assets from the discovery process and thoroughly examines them for potential vulnerabilities. The raw data resulting from the investigation must be analyzed and verified.

3. Validation

Tests vulnerabilities to ensure that all false positives and inaccuracies are removed from the raw investigation data. This often-neglected step ensures accuracy, painting a nearly complete picture of the security posture.

4. Exploitation

Involves the in-depth analysis and execution of advanced testing techniques against all verified vulnerabilities. This effort completes the security picture and provides the information necessary to fully mitigate the observations.

5. Reporting

Provides an overview of the assessment methodology, vulnerability and threat assessment observations, recommendations, and corrective actions, and a copy of all data collected.

Tools Used for Network Pentesting




A network vulnerability assessment is a network security practice that assists companies in identifying, quantifying, and prioritizing risks and vulnerabilities in their network architecture.

To put it another way, network vulnerability assessment is all about identifying your flaws before others do.

Vulnerability assessment tools can assist identify security issues, but they can’t tell you which ones are dangerous, and which aren’t. That’s why penetration tests are critical for identifying which vulnerabilities are dangerous and exploiting them purposefully but ethically.

Breach of network security is getting more regular and costly. And knowing the potential security flaws in the network infrastructure is crucial to prevent such breaches.

Conducting a network vulnerability assessment allows businesses to detect any system flaws before they are discovered by attackers. It also includes extensive instructions on how to address those flaws as quickly as possible.Not only that, but many compliance requirements, such as PCI-DSS, HIPAA, SOX, ISO, and others, demand network vulnerability assessment.

Standards such as PCI-DSS, PCI-3DS, PCI-CP, ISO 27001:2022, AICPA SOC, etc. require periodic performance of VA and PT, either as a direct requirement/control or as a risk mitigation practice.
