Network & Infrastructure Security

Network Security is a subset of Cyber Security, which specifically focuses on securing the network infrastructure and its components, such as routers, switches, firewalls, and other network devices.

Legacy networks were traditionally designed from the outside in, with a focus on classifying users as either “trusted” or “untrusted”. The network design process began at the outer edge, where the carrier handed off the network circuit to the data center. The necessary routers were then identified and connected to multiple types of networks. The infrastructure was then built and once the network was in place, users were free to connect wherever they wished.

Therefore, perimeter-based security is based on the concept of a trusted perimeter around the network. The model assumes that all devices and users within the network are trusted, and that the perimeter can be secured using Firewalls, Intrusion Detection and Prevention Systems, and other security controls.

Micro-Segmentation introduces an advanced network security model that offers greater control and protection by logically dividing network resources into distinct security segments, even down to individual workloads. Unlike traditional network segmentation, which focuses on creating sub-networks within the overall network, Micro-Segmentation provides granular security at the level of Virtual Machines (VMs) and individual hosts.

By leveraging network virtualization technology, Micro-Segmentation enables the creation of secure zones within data centers and cloud deployments. This approach isolates each workload and applies specific security controls tailored to its needs. The use of fine-grained security policies tied to individual workloads helps prevent attacks and limits an attacker’s ability to move laterally within the data center, even if they breach perimeter defenses.

The zero trust model flips the traditional network design approach by starting from the inside out instead of the outside in. This means that instead of classifying users as “trusted” and “untrusted,” the focus is on protecting the data or assets that require safeguarding, and the network is built around them. By eliminating the trust model from the network, Zero Trust provides sophisticated and detailed protection against data breaches and other network threats.

In a Zero Trust Architecture, every user, device, and application are assumed to be untrusted, and access is granted on a need-to-know basis, based on continuous authentication and authorization.

Our services include:

Network (IT) Security Policy

An IT Security Policy defines the rules and requirements for ensuring the confidentiality, integrity, and availability your organization’s IT assets, and provide a framework for implementing and enforcing security controls. Such a policy typically includes:

      • Access Control
      • Authentication and Authorization
      • Data Protection
      • Incident Response
      • Network Security
      • Physical Security
      • Third-Party Access

It also includes another important component being “Enforcement”. Once your organization has established multiple layers of protection, including firewalls, intrusion detection/prevention systems, access controls, and other security technologies, enforcement mechanisms are necessary to ensure that these security measures are being applied correctly and are effective.

Enforcement involves establishing policies, procedures, and guidelines that dictate how network security technologies and controls should be configured, monitored, and managed. It also involves assigning responsibilities to specific individuals or teams for maintaining the security of the network and enforcing compliance with security policies and procedures. This can include the regular testing of security systems, analyzing security logs for potential threats, and promptly addressing any security incidents or violations.

Network Security Assessment

To establish a baseline, we can perform various audits to assess the status and effectiveness of your network security measures. Auditing involves the examination and evaluation of network infrastructure, systems, and applications to ensure they comply with your organization’s security policies and standards. The main goal of auditing is to identify security gaps or vulnerabilities in the network and ensure that appropriate measures are taken to mitigate those risks.

There are different types of audits in network security, including network audits, system audits, application audits, and compliance audits.

Network Audits focus on examining the network architecture, infrastructure, and topology, as well as network devices such as routers, switches, and firewalls.

System Audits involve the examination of operating systems, servers, workstations, and other devices that are part of the network.

Application Audits focus on examining the security of software applications running on the network, including web applications, mobile apps, and desktop applications.

Compliance Audits are performed to ensure that the network is following regulatory and industry standards such as PCI DSS, HIPAA, and ISO 27001.

Network Security Design & Implementation

There are many important components involved in designing and implementing a network security architecture, for example:

      • Various Firewall implementations
      • Intrusion Detection and Prevention Systems (IDPS)
      • Virtual Private Networks (VPNs)
      • Network Access Control (NAC)
      • Security Information and Event Management (SIEM), Encryption
      • Patch Management
      • Data Loss Prevention (DLP)
      • Antivirus and Anti-Malware software
      • Application Security

Zero Trust Architecture Consulting

Over the past few years, the networking and security landscape has experienced a significant shift where work is no longer confined to a physical location but is instead an activity that can be performed from anywhere. As a result, hybrid work has become the new norm, causing your applications and users to be scattered everywhere, which has led to a significant expansion of your attack surface. In conjunction, we also have seen a surge in the level of sophistication and frequency of cyber-attacks aimed at exploiting this expanded attack surface.

Therefore, the traditional network security model is no longer sufficient and is being replaced by a new model that assumes every user, device, and application to be untrusted, and access is granted on a need-to-know basis, based on continuous authentication and authorization – the Zero Trust Model.

A Zero Trust Architecture is based on the following:

      • Identity-Centric Security
      • Micro Segmentation
      • Least Privilege Access
      • Continuous Monitoring and Analytics
      • Encryption and Data Protection
      • Adaptive Security Controls
      • Secure Access Everywhere

This results in three main areas:

      • Trust and Identity
      • Policy Enforcement
      • Visibility and Monitoring

A typical Zero Trust Architecture might include the following components:

      • Identity and Access Management (IAM)
      • Multi-Factor Authentication (MFA)
      • Device Identity and Management
      • Network Segmentation
      • Micro-Segmentation
      • Policy-Based Access Controls
      • Continuous Monitoring and Analytics
      • Encryption
      • API Security
      • Cloud Security
      • Endpoint Security
      • Remote Access Security
      • User Behavior Analytics (UBA)
      • Threat Intelligence Integration
      • Automated Security Orchestration

In most cases, moving to a Zero Trust Architecture without re-architecting the entire network is not a simple thing and requires a lot of expertise and experience. We can help you to accelerate your Zero Trust adoption by identifying and reviewing your business assets, optimize and automate your policies, and designing your Zero Trust architecture.
