Network Vulnerability Assessment: Summary

Network vulnerability assessment includes scanning for, detecting, and analyzing security vulnerabilities within a corporate network infrastructure and aims to ensure its resilience to common cybersecurity threats. 

It is required to carry out vulnerability assessment to comply with the majority of regulatory standards (HIPAA, PCI DSS, etc.). Usually, assessment is followed by penetration testing to exploit identified vulnerabilities and define most probable attack scenarios.

The assessment may take from 3-4 days (for a small network) to 2-3 weeks (for midsize and large networks). The process requires a team of a lead security engineer and a security engineer, and its cost starts from $5,000.

ScienceSoft’s security experts help midsize and large companies evaluate network security and unearth present security flaws. We can define the nature and criticality of network vulnerabilities and offer a remediation plan.

Network Vulnerability Assessment Methods

Depending on your testing needs, we apply black box, white box or gray box methods. 

Black box

Scanning for vulnerabilities without any information on a target network. The external network perimeter is a starting point for scanning.

Assessing the network vulnerability ‘from the inside’ (having all the knowledge about the network).

Searching for vulnerabilities in the network, having some information about it (e.g., user login details), but without access to the entire network.

Network Vulnerability Assessment Plan

ScienceSoft plans network vulnerability assessment, according to the complexity and size of your network infrastructure and the type of the targeted environment (production, development, etc.). Below, our security team shares a sample plan for conducting vulnerability assessment.

Network vulnerability scan planning and design

Duration: 1-10 days
  • Defining network vulnerability assessment goals (e.g., network segmentation check, malware scanning, preparing for HIPAA compliance audit).
  • Creating a checklist of the network segments and software to be assessed.
  • Selecting a vulnerability scanning tool that can be configured to bypass specific network firewall rules and restrictions.
  • Choosing between an external vulnerability scan (for the part of the network exposed to the internet) and an internal vulnerability scan (for the internal corporate network).
  • Scheduling the vulnerability scan (usually for non-business hours).


Configuring the scan

Duration: ~1 day
  • Defining target IPs by specifying hardware or software they belong to.
  • Adding the list of target IP addresses to the vulnerability scanning tool.
  • Scanning the network for open ports and defining port ranges and protocol types (TCP or UDP).
  • Setting up the aggressiveness level of the scan, its duration, and completeness notifications.

We typically set up scan aggressiveness at a medium level as a high scan may influence the performance of the entities you scan due to the increased consumption of network resources.

Scanning for vulnerabilities

Duration: 1-5 days
  • Scanning the targeted networks and software via manually tuned automated scanning tool.


Analysis of the scan results

Duration: 1-3 days

At this stage, we perform manual analysis of the scan findings:

  • To filter out false positives and validating the identified security vulnerabilities.
  • To analyse root causes and potential impact of the found vulnerabilities.

We recommend reaching out for penetration testing to see whether a real-life attacker can exploit the detected vulnerabilities.

Reporting the vulnerabilities discovered

Duration: 1-2 days

We draw up the final report on network vulnerability assessment, including:

  • A list of detected vulnerabilities with their description and classification by their severity.
  • Corrective measures for each vulnerability.
  • Vulnerability assessment methodology and tools.

Our cybersecurity consultants opt for performing network vulnerability assessment quarterly (monthly or weekly in case of strict compliance requirements) and each time after introducing major changes to the network (e.g., adding or removing hardware and software components).

Benefits of Vulnerability Assessment by ScienceSoft

Precise assessment scoping

We analyze your request and study testing targets to define the optimal testing scope. We aim to save your resources by not going beyond the necessary scope.

Complete view of vulnerabilities

We detect maximum vulnerabilities in your network. We identify the most critical and less significant vulnerabilities, so that you can prioritize remediation activities and wisely allocate resources.

Regulatory compliance (GLBA, HIPAA, PCI DSS, etc.)

We have hands-on experience with major regulatory standards. We will provide you a detailed roadmap to fix security gaps to achieve compliance.

Avoiding financial and reputational losses

Timely detection of network vulnerabilities helps prevent most cyberattacks and avoid workflow disruption, downtime, legal issues and non-compliance fines related to security breaches.

Tools We Employ for Network Vulnerability Assessment

During the vulnerability assessment projects, ScienceSoft’s cybersecurity engineers often use the following tools, as they provide high-quality assessment reports and frequently update their vulnerability databases.

Network Vulnerability Assessment Costs

Network vulnerability assessment costs may range greatly from project to project. Here we highlight essential vulnerability assessment cost factors:

  • The complexity of the network infrastructure.
  • Network size (the number of IPs, applications scanned, etc.).
  • The types and number of assessment goals (e.g., network segmentation check, malware scanning, checking compliance with HIPAA, PCI DSS, GDPR, etc.).
  • Service provision model (one-time or long-term, as long-term relationships with a vendor may reduce subsequent costs).

Note: In case of in-house network vulnerability assessment, additional costs also include vulnerability scanning tool licensing (usually charged as a subscription-based fee).

Here is a sample vulnerability assessment project with $5,000+ cost:

  • Assessment method: black box.
  • Assessment goal: assessing compliance with HIPAA.
  • The number of targeted IPs: up to 200.
