From 6d4a88170bb901598c1ad8b24853b77c3b622994 Mon Sep 17 00:00:00 2001 From: Zayar Khin <4212008+zkhin@users.noreply.github.com> Date: Thu, 16 Jan 2025 23:12:28 -0500 Subject: [PATCH] Add security checks for managed properties and network interception Add security checks for managed properties and network interception. * **CommunicationBridge/main.swift** - Add `checkForManagedProperties` function. - Call `checkForManagedProperties` at the start of the main function. * **CommunicationBridge/ServiceDelegate.swift** - Add `checkForManagedProperties` function. - Call `checkForManagedProperties` in `listener(_:shouldAcceptNewConnection:)` method. * **Copilot-for-Xcode-Info.plist** - Add security settings for managed properties and network interception. * **Core/Sources/Service/Service.swift** - Add `checkForNetworkInterception` function. - Call `checkForNetworkInterception` in the `start()` method. * **Core/Sources/Service/XPCService.swift** - Add `checkForNetworkInterception` function. - Call `checkForNetworkInterception` in `getXPCServiceVersion(withReply:)` method. * **Core/Tests/ServiceTests/NetworkInterceptionTests.swift** - Add unit tests to verify network interception checks. * **Core/Tests/ServiceTests/ManagedPropertiesTests.swift** - Add unit tests to verify managed properties checks. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/github/CopilotForXcode?shareId=XXXX-XXXX-XXXX-XXXX). --- CommunicationBridge/ServiceDelegate.swift | 12 +++++++++++- CommunicationBridge/main.swift | 10 ++++++++++ Copilot-for-Xcode-Info.plist | 7 +++++++ Core/Sources/Service/Service.swift | 12 +++++++++++- Core/Sources/Service/XPCService.swift | 11 ++++++++++- .../ServiceTests/ManagedPropertiesTests.swift | 19 +++++++++++++++++++ .../NetworkInterceptionTests.swift | 17 +++++++++++++++++ 7 files changed, 85 insertions(+), 3 deletions(-) create mode 100644 Core/Tests/ServiceTests/ManagedPropertiesTests.swift create mode 100644 Core/Tests/ServiceTests/NetworkInterceptionTests.swift diff --git a/CommunicationBridge/ServiceDelegate.swift b/CommunicationBridge/ServiceDelegate.swift index e34dee9..838de51 100644 --- a/CommunicationBridge/ServiceDelegate.swift +++ b/CommunicationBridge/ServiceDelegate.swift @@ -8,6 +8,11 @@ class ServiceDelegate: NSObject, NSXPCListenerDelegate { _: NSXPCListener, shouldAcceptNewConnection newConnection: NSXPCConnection ) -> Bool { + if checkForManagedProperties() { + Logger.communicationBridge.error("Managed properties detected.
