Network Security Assessment

Network Security Assessment

Network security assessment is a systematic process of evaluating the security of a computer network to identify vulnerabilities, weaknesses, and potential threats. The primary goal of a network security assessment is to assess the overall security posture of a network, identify potential risks, and recommend measures to mitigate those risks. This process is crucial for ensuring the confidentiality, integrity, and availability of network resources and data.

At Crystalline, we offer top-notch cyber security services to keep your business secure and your customers safe. Our team of experts specializes in network security assessment and we use the latest technologies to identify the weaknesses of your network.

Why Network Security Assessment Matters?

Network security assessments are a vital tool for organizations to proactively manage and enhance their cybersecurity defences. They help organizations of all sizes and industries to:

Provide a structured and systematic approach to understanding and managing cybersecurity risks.
Protect valuable assets, maintain compliance, and uphold trust in an organization's ability to safeguard data and systems.
Adhere to industry regulations and standards, avoiding potential legal and financial consequences.
Protect brand reputation by mitigating the risks.
Prepare for security incidents by identifying potential vulnerabilities and attack vectors.

Types of Testing

Vulnerability Scanning: Automated tools scan your network for known vulnerabilities, offering a quick overview of potential issues.
Penetration Testing: Skilled testers simulate real-world attacks to identify vulnerabilities and assess the overall security posture of your network.
Network Architecture Review: Experts review and evaluate the overall network architecture and design for security best practices and potential weaknesses.
Policy and Configuration Review: Analyse security policies, firewall rules, access controls, and configurations to ensure they align with security best practices and organizational policies.

Compliance and Regulatory Assessment: Assess that the network and security measures align with specific industry regulations and compliance standards.

These assessments can be conducted individually or in combination, depending on an organization's needs and objectives. Regularly performing a variety of network security assessments helps maintain a strong security posture and adapt to evolving threats in the ever-changing cybersecurity landscape.

Standards and Frameworks

CIS CSC

Developed by the Center for Internet Security (CIS), the CIS CSC provides a prioritized set of actions that organizations can take to improve their cybersecurity posture

PCI DSS

PCI DSS outlines security requirements for organizations that handle payment card data. It includes specific testing and assessment requirements to ensure the security of the network that process credit card transactions.

NIST SP 800-53

National Institute of Standards and Technology (NIST) provides a comprehensive framework for security controls and assessment procedures. Performing security testing against this standard provides a view of the network's security posture.

Process & Methogology

A typical network security assessment process and methodology involves a systematic and structured approach to identifying vulnerabilities and weaknesses in networks. Here is a step-by-step overview of a network security assessment process:

Objectives and Scope

01

Define the scope of the assessment, including the network's boundaries, systems, devices, and assets to be evaluated. This may include internal and external network components, such as routers, firewalls, servers, workstations, and applications

Vulnerability Scanning

03

Use specialized tools and techniques to scan the network for known vulnerabilities and weaknesses. Vulnerability scanning helps identify outdated software, misconfigurations, and common security issues

Policy and Configuration Review

05

Evaluate the network's security policies, rules, and configurations to ensure they align with best practices and security standards. This includes reviewing firewall rules, access control lists, and authentication mechanisms

Remediation and Retesting

07

Collaborate with development teams to address identified vulnerabilities. Conduct retesting to verify that vulnerabilities have been adequately remediated.

Information Gathering

02

Collect information about the network, such as network diagrams, IP addresses, domain names, and other relevant documentation. This phase may also involve passive reconnaissance, such as scanning for publicly available information about the network.

Penetration Testing

04

Involves simulating attacks to actively exploit vulnerabilities and weaknesses to determine their real-world impact. Penetration testing often requires more advanced skills and may be conducted by skilled security professionals

Reporting

06

Document all findings, including identified vulnerabilities, their severity, and recommendations for remediation. Provide clear and actionable reports to developers and stakeholders.

Final Reporting

08

Generate a final report summarizing the testing process, findings, and the status of remediation efforts. Provide recommendations for ongoing security practices and improvements.

It's important to note that network security assessment is an iterative process, and regular assessments should be performed to ensure ongoing security. Additionally, the specific methodology and tools used may vary depending on the organization's needs, technology stack, and compliance requirements.

Get Started on Securing Your Networks

Don't leave your networks and systems vulnerable to cyber threats. Protect your users, data, and reputation by investing in network security assessment. Schedule a consultation and take the first step towards a more secure online presence.

Remember, security is not a one-time task—it's an ongoing commitment. Stay ahead of threats with regular security testing and fortify your digital assets against even the most determined attackers.

Secure today for a resilient tomorrow.
