Introduction
Microsoft has recently intensified its stance on security by disabling ActiveX controls by default in Microsoft 365. This move replaces the previous setting that allowed users to enable controls with minimal restrictions, prompting a necessary change in how users interact with this legacy technology.
Key Details Section
- Who: Microsoft
- What: ActiveX controls are now disabled by default in Microsoft 365.
- When: This security update has begun rolling out, following its earlier implementation in Office 2024 LTSC.
- Where: This change impacts Microsoft 365 across all platforms globally.
- Why: The shift aims to enhance security by preventing potential malware or unauthorized code execution stemming from the use of ActiveX, which has a history of being exploited through documents.
- How: Users can still enable ActiveX controls via the Trust Center, but this requires administrative permissions, making it increasingly challenging to utilize this feature.
Why It Matters
This update highlights significant implications for enterprise IT infrastructure as it affects:
- Security and Compliance: Reducing the risk of vulnerabilities associated with ActiveX mitigates potential compliance issues.
- Legacy System Dependency: Many enterprises rely on ActiveX for legacy applications. Transitioning away from it may necessitate re-engineering efforts, which could be resource-intensive.
- Service Performance: With ActiveX being disabled, organizations may need to find alternative solutions for data integration and workflow automation.
Takeaway
IT professionals should evaluate the impact of this change on their existing systems and workflows. Consider exploring alternative technologies for application integration, such as Office Add-ins, while preparing staff for potential re-training on new platforms. Plan strategically for compliance, security, and the gradual transition from legacy solutions like ActiveX.
