Network Security 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 of the network to comply with the majority of regulatory standards (HIPAA, PCI DSS, etc.). Usually, assessment is followed by network penetration testing to exploit identified vulnerabilities and define the most probable attack scenarios.
This engagement may take from 3-4 days (for a small network) to 2-3 weeks (for midsize and large networks). It 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.
Risks of Network Security Flaws
Vulnerabilities in a network may enable cybercriminals to launch a variety of attacks to gain partial or full control of your IT assets.
As a result, they may disrupt your IT operations and damage or misuse your sensitive data. The risks of neglected network vulnerabilities include:
- Operational downtime.
- Financial losses.
- Litigations.
- Reputational damage.
According to security best practices, a company should undergo network vulnerability assessments quarterly. In case of strict compliance requirements, it may be necessary to scan your network monthly or even weekly. Also, you should consider vulnerability assessment after introducing any significant changes to the network: e.g., adding or removing critical hardware and software components. Our cybersecurity consultants warn that if you neglect proper vulnerability assessment for longer than a year, you are likely to become an easy target for hackers.
Network Vulnerability Assessment Methods
Depending on your network vulnerability testing needs, we apply the black box, white box, or gray box approach.
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.
Steps to Perform Network Vulnerability Assessment
ScienceSoft plans vulnerability assessment of a network according to its size and complexity and size and the type of the target environment (production, development, etc.). You are welcome to check out our sample plan below and use it as your network vulnerability assessment checklist.
1.
Network vulnerability scan planning and design
- Defining the assessment goals: e.g., network segmentation check, malware scanning, preparing for HIPAA compliance audit.
- Creating a list 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).
ScienceSoft
2.
Configuring the scan
- Defining target IPs by specifying the 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 scanning aggression at the medium level. It helps avoid the disruption of network operations, as a high scanning aggression level requires increased consumption of network resources.
3.
Scanning for vulnerabilities
- Checking the target network components with a manually tuned automated scanning tool.
ScienceSoft
4.
Analysis of the scan results
At this stage, we perform manual analysis of the scan findings:
- To filter out false positives and validate the identified security vulnerabilities.
- To analyze 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.
5.
Reporting the vulnerabilities discovered
We deliver an executive summary with the project highlights and a final report, which contains:
- A list of detected vulnerabilities with their description and classification by their criticality.
- Corrective measures for each flaw.
- The assessment methodology and tools.

Network Vulnerability Management Steps
An integral part of a sound security strategy, network vulnerability management is a continuous process of keeping an up-to-date inventory of network assets, assessing network security, and eliminating vulnerabilities.
Top Network Vulnerabilities and Ways to Handle Them
Weak access controls
- Easy-to-guess passwords.
- Single-factor authentication.
- Unrestricted or poorly restricted access to sensitive information or critical network components.
Vulnerable software
- Deprecated or unpatched software.
- Misconfigured software, including security services and tools.
Insecure network architecture
- Absent or inefficient network segmentation that, in case of a breach, will enable intruders to freely move around the network and easily reach its critical components.
Low security awareness
- Employees breaking security rules due to negligence or ignorance: e.g., clicking malicious links, connecting unsecured devices to the network, accessing corporate IT network via public Wi-Fi without VPN, etc.
Network Vulnerability Assessment Checklist
Take our quick quiz and learn whether you need to improve your network security controls.
Have you implemented role-based access control to ensure that the users only have access to the network resources necessary to perform their tasks?
Are there strong authentication measures, such as complex passwords and multi-factor authentication, to control access to network resources?
Are critical assets, including sensitive data, isolated in separate network segments with increased security?
Is a demilitarized zone (DMZ) set up properly and isolated from the internal network?
Have strong encryption protocols been implemented to protect client-server communication?
Do you use a VPN for a secure connection between remote devices and your central network?
Do you have properly configured firewalls to control network traffic?
Is anti-malware installed across the network devices?
Do you use email security solutions for email encryption and malware scanning, spam filtering, etc.?
Have you implemented efficient network monitoring and traffic analysis tools (e.g., IDS/IPS, SIEM)?
Is network hardware and software regularly patched and updated?
Do you perform regular network vulnerability assessments and pentests?
Does your organization provide consistent training to educate employees about network security threats and ways to handle them?
Have you assessed the cyber resilience of your staff through social engineering testing?

- Network size (the number of IPs, applications scanned, etc.).
- Applied assessment method (automated scanning, manual assessment, or a combined approach).
- Service provision model (one-time or long-term, as long-term relationships with a vendor may reduce subsequent costs).
- The need for a follow-up penetration testing to investigate the potential impact of the detected vulnerabilities’ exploitation.

Common Questions About Network Security
What are the pillars of network security?
- Full visibility of network components that enables their timely vulnerability management.
- Strong network access controls.
- Properly configured security tools: firewalls, antivirus, DLP, IPS, SIEM, and others.
- Adherence of all network users to security rules and best practices.
- Regular security checkups: vulnerability assessment and penetration testing.
What is the most vulnerable part of the network?
Mobile devices, such as smartphones, laptops, and tablets, especially those used by remote employees, are considered the major sources of network vulnerabilities: outdated software, weak passwords, misconfigured firewalls and other security tools, insecure connections, etc. With these devices, it is difficult to control if the necessary security measures, such as vulnerability patching or security updates, are applied consistently. In addition, mobile devices often get lost or stolen.
