Securing Data Centers: Limiting Access and Federation between On-Premises and Cloud

Limiting Access and Federation between On-Premises and Cloud

As organizations continue to rely on cloud services and on-premises infrastructure, it is essential to understand the risks associated with sharing data and authentication between these two environments. While sharing data and authentication between cloud assets and on-premises infrastructure has its benefits, it also introduces potential weaknesses that can be exploited by attackers.

Risks of Federation and Access

The recent SolarWinds supply chain attacks highlighted the importance of securing federation and access between on-premises and cloud environments. The attacks exploited vulnerabilities in Active Directory Federation Services, allowing attackers to gain unauthorized access to sensitive data. This demonstrates the need for organizations to understand the risks involved and implement additional monitoring resources to review authentication processes.

Microsoft 365 Security Defaults and Settings

If you are a customer of Microsoft 365, it is essential to review your security defaults and settings. Microsoft and other entities, such as the Center for Internet Security, have updated and revised benchmarks over the years. Some benchmarks require manual steps, while others are more automated. It is crucial to ensure that your security settings are up-to-date and aligned with the latest best practices.

Conclusion

Limiting access and federation between on-premises and cloud environments is a critical aspect of securing data centers. By understanding the risks involved and implementing additional monitoring resources, organizations can reduce the likelihood of unauthorized access and data breaches. Regularly reviewing security defaults and settings is also essential to ensure that your organization is protected from potential threats.
