Overview
Network Security Assessment & Review (NSAR) is the process of evaluating an organization’s entire network across on-premises and cloud environments like AWS to identify and remediate security issues that could be exploited by attackers. This includes reviewing how your network is architected, how data flows across systems, and how secure your devices, cloud resources, and operational processes are.
Since networks form the backbone of digital infrastructure, securely connecting servers, users, applications, and cloud services, it's crucial to ensure they are properly segmented, monitored, and hardened. A weak or misconfigured network whether in a physical data center or an AWS VPC can lead to unauthorized access, data breaches, or service disruptions.
The main goal of NSAR is to uncover and fix vulnerabilities before they are exploited. The review typically includes:
- Assessment of overall network architecture and segmentation
- Firewall, router, switch, and VPN configuration review
- Identification of open ports, exposed services, and risky protocols
- AWS-specific evaluations, such as VPC design, security group rules, IAM policies, cloud firewall configurations, and S3 bucket permissions
The assessment uses a combination of automated tools and expert-led analysis to review all network layers. In cloud environments like AWS, NSAR examines services such as EC2, VPC, RDS, CloudTrail, GuardDuty, and IAM configurations, ensuring that security controls are properly implemented and monitored.
The evaluation covers internal and external networks, cloud platforms, remote access setups, and hybrid architectures. It aligns with industry frameworks like ISO 27001, CIS AWS Benchmarks, NIST, and regulatory standards such as PCI DSS and HIPAA.
By performing a Network Security Assessment, organizations can gain visibility into their current security posture, identify gaps in cloud and on-prem configurations, enhance resilience, and ensure alignment with compliance and governance requirements.
Highlights
- Identify vulnerabilities and misconfigurations across internal and external network environments.
- Evaluate network design, segmentation, and device configurations against security standards.
- Improve compliance and reduce risk through actionable recommendations based on thorough network analysis. The evaluation often follows industry best practices and aligns with security standards such as ISO 27001, CIS Benchmarks, and regulatory frameworks like PCI DSS or HIPAA.
