macOS Introduces New Security Layer to Prevent Admin Errors
Organizations often overlook configuration oversights, creating vulnerabilities that can be exploited by attackers. To address this issue, ThreatLocker has introduced a new feature called Defense Against Configurations (DAC), aimed specifically at enhancing security on macOS.
New Security Layer for macOS
DAC for macOS, currently in Beta, follows the successful August 2025 release for Windows. This feature seeks to identify and correct configuration weaknesses that could lead to security breaches. It identifies issues such as:
- Unencrypted drives
- Disabled firewalls
- Legacy file-sharing protocols like SMB v1
- Default settings that are left vulnerable
Frequency and Focus of Scanning
The ThreatLocker agent performs routine configuration scans on Macs, executing up to four times a day. Initially, the focus is on key security controls, including:
- Disk encryption status (FileVault)
- Built-in firewall status
- Remote access settings (remote login)
- Local administrator accounts and membership checks
- Automatic update settings
- Gatekeeper and app source controls
- Security and privacy preferences
These findings are organized by endpoint and category, with clear guidance provided for remediation. The mapping with major frameworks, including CIS, NIST, ISO 27001, and HIPAA, allows organizations to align with comprehensive security requirements.
Importance of DAC for Creative Teams
For design firms, media studios, and production teams using Macs, security visibility is critical. While the M-series processors are efficient for creative software, security measures have lagged behind. DAC ensures these teams can proactively identify and remedy weak spots in their security posture.
With DAC, when an issue is flagged, it not only points out the problem but also connects it with actionable ThreatLocker policies. This feature enhances IT and security teams’ understanding of their configurations and elevates their ability to fortify their environments without unnecessary guesswork.
Ultimately, DAC’s integration into macOS enhances organizational security by providing vital insights, helping meet insurance requirements, and improving compliance with industry standards. This shift represents a significant step toward empowering teams to manage their security effectively while leveraging the benefits of their macOS devices.
