Companies are relying increasingly on cloud service providers for conducting business, including storing data, hosting email, and more. But with the increasing regulatory focus on the risk of cloud data storage, is the forecast for cloud solutions stormy?
ACA Aponix recently hosted the webcast Enhancing the Security of Your Office 365 Environment. Kris Lau, Managing Director at ACA Aponix, along with John Manganiello, Head of Business Development at RFA, and Michael Asher, RFA’s CIO, discussed their thoughts and guidance on the security of cloud solutions, particularly Microsoft® Office 365®, as well as security risks companies should be aware of and specific steps they can take to enhance their cloud security posture.

Highlights of the webcast include:
Regulators are Cloud-Watching
It’s increasingly clear that regulators are interested in how companies are securing their data when using cloud solutions.
The U.S. Securities and Exchange Commission’s (SEC), including the SEC’s Office of Compliance Inspections and Examinations (OCIE), have specifically targeted cloud solution security. In May, the SEC commenced a cyber compliance examination sweep of registered investment advisers (RIAs) which included a focus on cloud service provider risk. Also in May, OCIE issued a Risk Alert on cloud and network data storage solutions.
On the cloud service provider side, the U.S. Cloud Act obligates service providers to comply with search warrant requirements regardless of whether the data is stored inside or outside the U.S.
Privacy regulations such as the EU’s General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and others extend to data stored in the cloud as well.
Maintaining a secure cloud environment is therefore key, not just for protection of company information, but to stay on the right side of regulators.
Who’ll Stop the Rain?
Gone are the days when companies could rely on firewalls to protect themselves from the storms caused by outside forces. According to the 2018 NSCP/ACA Aponix Cybersecurity Compliance Programs Survey, nearly 70% of firms are using a cloud-based email provider. Combined with employees accessing company data from insecure locations, using their own devices, sharing data and access with outsiders, and more, security is far more complicated than it used to be.
It’s Still Leaky Up There
Office 365, Amazon Web Services, Microsoft Azure, and other cloud services all have their own security features, with many settings enabled by default. Additionally, cloud service providers have their own levels of internal security for their data storage facilities. Further, changes in cloud security structures may be on the way, particularly with a move to more certificate-based authentication schemes that may reduce the need for passwords and move security to an individual machine basis.
But relying solely on protection from the sky is not recommended. Companies must be proactive regarding data security, in combination with the protections that cloud providers afford. Companies should take active roles in due diligence, user management, access controls, auditing, retention, and security configurations.
Blame for the Rain? The Fault is in Default
Office 365 includes some built-in security features (including its “Secure Score” module), but many settings need to be appropriately configured by the system administrator. Moreover, out-of-the-box default settings are typically insecure.
For example, without additional configuration:
- All services are enabled, even if unused
- Restrictions on sharing are loose
- Bypassing of third-party SPAM filtering and archiving may be possible
- Multi-factor authentication is not enabled
- Not all auditing is enabled
- No retention policies are in place
Dive Deep into the Clouds
It’s advisable for companies to go beyond default security settings provided by Office 365 and other cloud service providers. Evaluate possible solutions, assess specific needs, test settings, and identify what works and what can work better.
