Cloud Workload Protection Platform for DNS Reputation Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Protecting corporate cloud-based services and infrastructure from cyber threats is challenging due to dynamic network environments and expanded security perimeters, which introduce vulnerabilities from remote workers, cloud devices, and untrusted traffic sources.
Innovation Solution
Implementing a system that determines the approval status of data streams and transmits fetch requests to a renderer for network resources requested by protected clients, using a reputation-based global threat engine for real-time access controls, monitoring, and auditing, while preventing lateral attacks and unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network security perimeters are expanded to include remote workers, mobile devices, and cloud devices, then accessibility and flexibility are improved, but vulnerabilities and security risks increase
Solution Approach 1:
A cloud-based security platform acts as an intermediary between protected clients and network resources. The platform intercepts DNS requests, performs reputation-based filtering, and controls access to network resources, thereby mediating security risks while maintaining expanded network accessibility.
Solution Approach 2:
The system performs preliminary security checks by evaluating the reputation of DNS requests before allowing access to network resources. By pre-assessing the trustworthiness of requested domains and IPs, the system prevents malicious traffic from reaching protected devices, addressing security vulnerabilities before they can cause harm.
2Ease of operation
If traditional network-based security approaches are used, then infrastructure control is maintained, but visibility and protection of remote traffic are lost
Solution Approach 1:
The security system transitions from traditional network-perimeter-based protection to a cloud-based, application-layer security model. By moving security controls to the cloud and implementing DNS-level filtering, the system extends visibility and control to remote traffic without requiring changes to local network infrastructure.
Solution Approach 2:
The cloud-based security platform provides universal protection across multiple devices, locations, and network environments through a single centralized system. It handles DNS requests from any protected client anywhere in the world, providing consistent security policies and visibility across the entire expanded network perimeter.
3Reliability
If zero-trust principles are implemented across all traffic, then security is improved, but system complexity and processing overhead increase
Solution Approach 1:
The system applies differentiated security evaluation to different DNS requests based on their reputation scores and contextual factors. Rather than uniformly treating all traffic with the same level of scrutiny, it dynamically adjusts security measures based on the specific risk profile of each requested resource, optimizing both security and performance.
4Measurement precision
If comprehensive threat intelligence is collected and analyzed, then detection accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The system pre-evaluates and caches reputation information for DNS requests, performing security assessments before traffic needs to be routed. By maintaining updated reputation databases and pre-assessing domain trustworthiness, the system enables rapid real-time decisions without extensive processing delays during actual traffic flow.
Data Source
AI summary
Systems, methods, apparatuses, and computer program products for providing a virtual cloud workload protection platform. One method may include determining, by a device, whether a data stream is approved or unapproved; and transmitting, by the device, a fetch request to a renderer requesting a network resource requested by a protected client. Another method may include receiving, by a rendering device, a fetch request from a device requesting at least one network resource requested by a protected client; requesting, by the rendering device, the requested at least one requested resource; and rendering, by the rendering device, the at least one requested resource.
