Case Study
The client is a mining company in Australia. They did not have a standardized vulnerability management program due to which the security risk was high.
Infosys, with a proven capability model and matured execution process, established a unified approach to manage the vulnerabilities from detection to remediation, thereby reducing more than 80% vulnerabilities.
Key Challenges
- No vulnerability scanning for more than 12 months
- Huge backlog of vulnerabilities posing high risk of cyber-attacks
- Lack of security awareness and ITIL processes increased number of vulnerabilities and security risk
- No standard SLAs for scanning and timely remediation
- Multiple and diverse remediation teams leading to increase in operations effort
The Solution
Developed risk-based model to remediate vulnerabilities
Created risk-based model prioritizing assets and vulnerabilities for remediation
Assisted in asset classification which was challenging due to mix of IT and OT assets
Created inventory of all devices in the enterprise to help in planning of upgrades and future assessments
Coordinated and assisted different owners for effective remediation
Defined escalation matrix, SLAs, and RACI and aligned them with rightly identified owners
Tracked vulnerabilities using ITSM (ServiceNow) tool and performed reverification scans to validate the applied fixes
Benefits
Faster and effective remediation of vulnerabilities
Reduced overall risk by identifying known security exposures
Resolved more than 80% backlog of vulnerabilities
Standardized vulnerability management program by documenting learnings and gaps post the unified vulnerability reduction approach
Reduced manual efforts from 20 hours to 15 minutes by automating vulnerability reports per ownership
