NETWORK AND IT INFRASTRUCTURE SECURITY

Network and IT Infrastructure Security: Building Resilient, Secure Foundations

In an increasingly connected digital world, securing your network and IT infrastructure is essential to protecting critical business operations and sensitive data. As organizations face an ever-growing number of sophisticated cyber threats, from ransomware to insider attacks, a robust network security strategy is essential to defend against breaches and maintain operational integrity.

At Cratos Can Inc., we deliver comprehensive Network and IT Infrastructure Security solutions that ensure your organization’s critical systems are protected, resilient, and compliant with modern cybersecurity standards. Our solutions are designed to secure network access, optimize platform security, and implement advanced segmentation techniques such as micro-segmentation and Zero Trust architectures to keep your business safe from both external and internal threats.

Key Components of Network and IT Infrastructure Security

Network Access Control (NAC)
Securing network access is the first line of defense in protecting your infrastructure. NAC ensures that only authenticated and authorized users or devices can connect to your network, reducing the risk of unauthorized access or data breaches. Our NAC solutions provide granular control over who or what can access your network, enforcing security policies based on identity, device type, and security posture.
  • a. Device and User Authentication: We use multi-factor authentication (MFA) and secure access protocols to verify users and devices before they gain network access.
  • b. Policy Enforcement: Security policies tailored to your organization ensure that access is granted based on roles, responsibilities, and device security status.
Platform Security Solutions
Platform security encompasses the protection of your IT infrastructure, including servers, endpoints, and cloud platforms. Our platform solutions are designed to harden your systems against attacks, vulnerabilities, and unauthorized access. From endpoint detection and response (EDR) to server hardening and secure cloud configurations, we protect every layer of your infrastructure.
  • a. Endpoint Security: Continuous monitoring and threat detection across all connected devices, with rapid response capabilities to stop attacks before they cause damage.
  • b. Server and Cloud Protection: Securing cloud-based and on-premises servers through proper configurations, regular updates, and proactive threat management.
Network Segmentation and Micro-Segmentation
Network segmentation divides your network into smaller, isolated sections to limit the spread of an attack and contain security threats. Each segment can be secured with tailored policies that restrict user and device access to only what is necessary for business functions. This approach not only improves security but also enhances compliance and simplifies monitoring.

Micro-segmentation takes this a step further by applying security controls at a more granular level, down to individual workloads or devices. By isolating critical assets and sensitive data, even lateral movement within the same network is tightly controlled. This prevents attackers from easily jumping between different segments and minimizes the blast radius in case of a breach.
  • a. Isolate Sensitive Data: Separate high-value assets from less critical components to mitigate risk.
  • b. Granular Control: Apply tailored security controls to individual segments, ensuring strict access to sensitive data.
Zero Trust Security Architecture
Traditional network security models operate on the assumption that everything inside the network is trusted. However, with the rise of insider threats and advanced persistent attacks, the Zero Trust model is the new standard in cybersecurity. Zero Trust assumes that no user or device, whether inside or outside the network, is trusted by default.

Cratos Can Inc. implements Zero Trust architectures by enforcing strict verification of every user and device, monitoring all traffic, and applying least-privilege access controls. Continuous authentication and real-time monitoring are fundamental to this approach, ensuring that trust is never assumed but always verified.
  • a. Least Privilege Access: Limit access to only what is necessary for each user or device, minimizing the attack surface.
  • b. Continuous Verification: Users and devices must continuously authenticate to access systems and data, reducing the risk of lateral movement within the network.
Network Traffic Monitoring and Threat Detection
Advanced threat detection capabilities are essential for early identification of potential breaches or malicious activity. We deploy real-time monitoring tools that analyze network traffic, detect anomalies, and provide actionable insights to mitigate threats quickly. By leveraging machine learning and AI-driven tools, our solutions identify suspicious activity before it escalates into a full-blown attack.
  • a. Real-Time Visibility: Continuous monitoring of network traffic to detect anomalies and unauthorized activities.
  • b. Threat Intelligence: Use of AI and threat intelligence to predict, detect, and respond to threats before they cause damage.

Use Case:
Implementing Network and IT Infrastructure Security for a Financial Institution

Industry: Finance
Client: Mid-Sized Financial Institution
Objective: Secure network access, protect sensitive financial data, and implement Zero Trust architecture to mitigate insider and external threats.

Client Situation:
A mid-sized financial institution with multiple branch offices and remote workers faced increasing cyber threats targeting its network and financial data. The organization needed a security solution that would not only secure remote access but also protect critical systems such as customer databases, payment systems, and internal financial platforms. Existing network infrastructure was not segmented, increasing the risk of lateral movement in case of a breach.

Challenges:

  1. Multiple access points, including remote workers and third-party vendors, increased the risk of unauthorized access.
  2. Lack of network segmentation made the entire network vulnerable to lateral movement if breached.
  3. Regulatory requirements, such as PCI DSS, mandated strict controls over sensitive financial data.

Solution: Cratos Can Inc.’s Network and IT Infrastructure Security

  1. Network Access Control (NAC)
    We implemented NAC to ensure that only authorized users and devices could access the financial institution's network. Multi-factor authentication (MFA) was enforced for all remote workers and external vendors, adding a strong layer of security to the authentication process.
  2. Network Segmentation
    The network was segmented to isolate sensitive financial systems (such as payment processing and customer databases) from less critical areas of the network. Each segment had specific access policies and monitoring, minimizing the risk of unauthorized lateral movement within the network.
  3. Micro-Segmentation for Critical Data
    Micro-segmentation was applied to particularly sensitive assets, such as the internal financial platform and customer records database. This ensured that even if one segment was breached, attackers could not easily access other parts of the network without triggering additional authentication and security controls.
  4. Zero Trust Implementation
    A Zero Trust architecture was deployed to eliminate implicit trust within the network. Every access request, whether from internal employees or external vendors, was continuously verified based on user identity, device, and security posture. Least-privilege access was enforced, ensuring users only had access to the systems and data necessary for their roles.
  5. Threat Detection and Real-Time Monitoring
    We implemented continuous network traffic monitoring with AI-powered threat detection to identify anomalies and detect potential threats in real time. The financial institution’s IT team received instant alerts for any suspicious activities, allowing them to respond swiftly to prevent breaches.

Results:
 

  1. Enhanced Security Posture:
    The financial institution significantly reduced the risk of unauthorized access and lateral movement within the network. The segmentation of critical systems and Zero Trust architecture provided multiple layers of defense against insider and external threats.
  2. Regulatory Compliance:
    With stronger access controls and detailed monitoring, the institution met PCI DSS requirements, ensuring the secure handling of payment card data and sensitive financial information.
  3. Operational Efficiency:
    Automated access control and micro-segmentation improved security without impacting the productivity of employees, contractors, or external vendors.
