Key Areas Covered by the iOS CIS Benchmark

The iOS CIS Benchmark covers a broad spectrum of security settings and configurations. Here are some of the key areas it addresses:

Password Policies: Recommends enforcing strong, unique passwords and using biometrics (Face ID or Touch ID) for authentication. Strong password policies are a fundamental aspect of security, and the iOS CIS Benchmark provides detailed guidance on how to implement them effectively. By enforcing strong, unique passwords, you can make it more difficult for attackers to gain unauthorized access to your devices. Biometrics, such as Face ID and Touch ID, provide an additional layer of security and make it more convenient for users to authenticate themselves. The iOS CIS Benchmark also recommends disabling simple passcodes, which are easier for attackers to guess.
Device Security: Covers settings related to device locking, screen timeout, and remote wipe capabilities. Device security is critical for protecting sensitive data on mobile devices, and the iOS CIS Benchmark provides comprehensive recommendations in this area. By configuring device locking and screen timeout settings, you can prevent unauthorized access to your devices when they are unattended. Remote wipe capabilities allow you to erase the data on your device if it is lost or stolen, protecting your sensitive information from falling into the wrong hands. The iOS CIS Benchmark also recommends enabling Find My iPhone, which can help you to locate your device if it is lost or stolen.
Network Security: Includes recommendations for Wi-Fi settings, VPN configurations, and cellular data usage. Network security is essential for protecting your devices from cyber threats when they are connected to the internet, and the iOS CIS Benchmark provides detailed guidance on how to configure your network settings securely. By using strong Wi-Fi passwords and disabling auto-join on public Wi-Fi networks, you can reduce the risk of eavesdropping and man-in-the-middle attacks. VPN configurations can encrypt your internet traffic and protect your data from being intercepted. The iOS CIS Benchmark also recommends limiting cellular data usage to prevent excessive charges and potential security vulnerabilities.
Data Protection: Focuses on encrypting data at rest and in transit, as well as disabling unnecessary services and features. Data protection is a critical aspect of security, and the iOS CIS Benchmark provides comprehensive recommendations on how to protect your sensitive information from unauthorized access. Encrypting data at rest and in transit helps to prevent data breaches and ensures that your data is protected even if your device is lost or stolen. Disabling unnecessary services and features reduces the attack surface of your device and minimizes the risk of potential vulnerabilities. The iOS CIS Benchmark also recommends enabling iCloud Keychain, which can securely store your passwords and credit card information.
Privacy Settings: Provides guidance on configuring privacy settings to limit data collection and tracking by apps and services. Privacy settings are essential for protecting your personal information from being collected and tracked by apps and services, and the iOS CIS Benchmark provides detailed guidance on how to configure these settings securely. By limiting location services, advertising tracking, and contact sharing, you can reduce the amount of data that is collected about you and protect your privacy. The iOS CIS Benchmark also recommends reviewing app permissions regularly to ensure that apps are only accessing the data that they need.
