Solution Overview

Problem

Traditional systems for deploying signed certificates on backup servers and client devices are slow and ineffective, particularly in heterogeneous computing environments, leading to inadequate security during backup operations.

Innovation Solution

A method and system for identifying trust levels of backup servers and clients, deploying signed certificates corresponding to these trust levels, and assigning backup tasks based on sensitivity levels to ensure secure data transfer and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual certificate deployment is used on backup servers, then security level is improved, but deployment time and operational efficiency deteriorate

Engineering Contradiction:
Improvesecurity levelVSAvoiddeployment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary security assessments and trust level determinations for backup servers before certificate deployment. Security characteristics are evaluated in advance, and certificates are deployed automatically based on pre-determined trust levels, eliminating the need for manual administrator intervention and significantly reducing deployment time while maintaining security standards

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The backup servers perform self-assessment of their security characteristics and automatically receive appropriate certificates based on their determined trust levels. The system enables servers to service themselves through automated evaluation and certificate deployment processes, eliminating manual administrator work and accelerating the certificate deployment timeline

Inventive Principle:
Principle #25Self-service

2Productivity

If standardized certificate deployment process is used, then deployment efficiency is improved, but security level and adaptability to heterogeneous environments deteriorate

Engineering Contradiction:
Improvedeployment efficiencyVSAvoidsecurity level
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system applies different certificate security levels and deployment methods to different backup servers based on their individual trust levels and security characteristics. Rather than using a one-size-fits-all approach, each server receives customized certificate treatment appropriate to its assessed security posture, maintaining both high security standards and deployment efficiency across heterogeneous environments

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts certificate deployment parameters based on the trust level of each backup server. Security characteristics such as encryption strength, validation requirements, and certificate types are modified according to the assessed trust level, enabling efficient automated deployment while maintaining appropriate security levels for each specific server

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If automated certificate deployment is implemented, then operational complexity is reduced, but security verification difficulty increases

Engineering Contradiction:
Improveoperational complexityVSAvoidsecurity verification difficulty
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The system implements continuous feedback loops where backup servers periodically report their security status and task completion. The certificate authority receives feedback on server performance and security incidents, automatically adjusting trust levels and certificate validity periods. This feedback mechanism maintains simple automated operations while ensuring ongoing security verification through performance monitoring and adaptive certificate management

Inventive Principle:
Principle #23Feedback

AI summary

The disclosed computer-implemented method for performing secure backup operations may include (i) identifying a group of backup servers with heterogeneous computing environments that provide backup services for a backup client, (ii) determining, for each backup server within the group, a trust level of the backup server by identifying at least one security characteristic of the backup server, (iii) deploying, on each of the backup servers, a signed certificate that enables the backup server to transfer backup data with a security level that corresponds to the trust level of the backup server, and (iv) performing secure backup operations for the backup client by (a) identifying a sensitivity level of a backup task initiated by the backup client and (b) assigning the backup task to a backup server within the group of backup servers that has a signed certificate with a security level appropriate for the sensitivity level of the backup task.
