Study Notes
- Mobile devices often use screen locks to prevent unauthorized access to information.
- Screen lock options can include facial recognition, PINs, fingerprint scanning, and swipe patterns.
- Failed access attempts trigger security measures like data wiping or device lockout.
- iOS devices erase after 10 failed attempts, while Android devices lock and prompt for Google credentials, potentially wiping data if incorrect credentials are provided.
- Locator applications use built-in GPS to help find lost devices, with options to play a sound, get directions, display a message, or remotely erase the device.
Mobile Device Updates and Encryption
- Keep mobile devices updated with the latest security patches and OS enhancements.
- Most mobile devices have automatic updates enabled by default.
- Full disk encryption protects data on mobile devices.
- iOS uses passcode-based encryption, while Android has integrated full device encryption, often enabled by default.
- Backing up mobile device data is crucial due to the ease of damage or loss.
- Mobile operating systems often provide automatic data backups to the cloud via wireless and mobile networks.
- Lost or damaged devices can be replaced, and data can be restored from the cloud backup.
Security Threats and Protections
- Attackers target mobile devices for personal data through malware and vulnerabilities.
- iOS's closed environment makes it harder for malware to be installed.
- Android's open nature allows app installations from various sources, increasing the risk of Trojan Horses.
- Applications run in sandboxes, limiting their access to device data and resources.
- Antivirus and anti-malware options are available for both iOS and Android.
- Mobile devices primarily initiate outbound data flows, reducing the default need for a firewall.
- Firewalls are not standard on mobile devices, but some are available, mainly for Android, with limited widespread use.
Enterprise Mobile Security
- Mobile Device Managers (MDMs) control data access within enterprise environments.
- MDMs manage both company-owned and employee-owned (BYOD) devices through security policies.
- MDMs address challenges of securing devices with both personal and corporate data.
- MDM policies manage app types, data storage locations, and resource availability based on location.
- System administrators may restrict features like cameras based on location (e.g., disabling in the office).
- Data separation via partitioning allows administrators to remove company data while preserving personal data upon employee departure.
- Policies can enforce screen locks and PIN requirements for device access.
Internet of Things (IoT) Security
- IoT devices connect more devices to networks at home and work.
- IoT examples include smart sensors for heating/cooling, networked lighting, and home automation features like doorbells and garage door controls.
- Wearable devices and sensors in building systems also fall under IoT.
- IoT devices from various manufacturers may have different functionalities and potential vulnerabilities.
- Segmenting IoT devices onto a separate network segment with restricted access can enhance security and limit the impact of potential breaches.
- Companies specializing in IoT devices may lack IT security expertise, necessitating security measures like network segmentation.
