Internet Explorer 11 is disabled or removed (Intune)

🔐 Why ACSC Recommends Disabling IE11:

⚠️ 1. End of Support

• Microsoft officially ended support for IE11 on June 15, 2022 (for most versions of Windows 10).

• No more security updates, patches, or stability fixes.

⚠️ 2. High Exploit Target

• IE11 has a long history of critical vulnerabilities, such as:

  • Remote code execution (RCE)

  • Memory corruption

  • ActiveX/Flash abuse

• Attackers often use IE-specific exploits in phishing and drive-by attacks.

⚠️ 3. Legacy Rendering Engine (Trident)

• Many exploit kits target older web rendering engines like Trident (used by IE).

• Even viewing a malicious website could result in compromise without user interaction.

⚠️ 4. ACSC Hardening Guidance

The ACSC includes IE11 disablement as part of:

• Application Hardening

• Mitigation of phishing and web-based malware delivery

• Essential Eight: especially under Application Control and Patch Applications

From ACSC guidance:
“Disabling Internet Explorer mitigates the risk of exploitation of its known vulnerabilities, especially when opening untrusted content such as email attachments or web links.”
