Case Study - ISP ISO27001

Written by HQ | Dec 18, 2024 5:08:34 PM

Problem:  

A medium-sized Internet Service Provider (ISP) utilising Microsoft 365 and Azure infrastructure had a specific requirement to enhance the security of their IT environment. Their challenge was to determine the appropriate security controls for Azure and Microsoft 365 while aligning with their risk appetite. Their chosen framework was ISO 27001. 

Response: 

In response to the client's requirement, Toro assessed the organisation's threat profile to gain a comprehensive understanding of potential risks and vulnerabilities in their Azure and Microsoft 365 environments. The organisation's risk appetite was carefully evaluated to determine the appropriate levels of security controls needed to protect its infrastructure effectively. Based on the threat assessment and risk appetite determination, ISO 27001 was then leveraged to guide the implementation of security measures. 

Outcome: 

The implementation efforts led to several noteworthy outcomes. We helped apply enhanced security controls within the Microsoft environment. 

To enhance the security posture and remediate vulnerabilities, the implementation of Microsoft Defender for Cloud was recommended. This tool seamlessly integrated with Azure and provided advanced threat protection capabilities. 

We also supported the implementation of the Microsoft Cloud Security Benchmark, which encompasses a wide range of security domains, including Network Security, Identity Management, Privileged Access, Data Protection, Asset Management, Logging and Threat Detection, Incident Response, Posture and Vulnerability Management, Endpoint Security, Backup and Recovery, DevOps Security, Governance, and Strategy. 

By assessing their threat profile, determining risk appetite, and aligning with the Microsoft Cloud Security Benchmark, the medium-sized challenger ISP successfully enhanced its security posture for Azure and Microsoft 365. The application of Microsoft baselines and the adoption of Defender for Cloud further fortified their defences, ensuring comprehensive protection against a wide range of cybersecurity threats.
