Whitepaper: Applying Secure Configurations to Enterprise Mobility
Introduction
Enterprise mobility has revolutionized the modern workplace, providing unparalleled flexibility and productivity. However, it also introduces significant security risks. As enterprises embrace mobile solutions, applying secure configurations becomes critical. This whitepaper outlines comprehensive strategies for implementing secure configurations in enterprise mobility, focusing on managed configurations, deployment scenarios, and essential security considerations.
Managed Configurations
Effective management of mobile devices involves several critical components. This section delves into the essential aspects of secure configuration.
Application Control
Application control ensures that only approved apps can be installed and used. Implementing strict policies to whitelist or blacklist applications prevents the installation of malicious software. Using Mobile Application Management (MAM) tools, enterprises can enforce app usage policies, restrict access to sensitive data, and ensure compliance with regulatory requirements.
Password Management
Strong password policies are the first line of defense against unauthorized access. Enterprises should enforce complex password requirements, including minimum length, character diversity, and regular updates. Integrating password management tools can help users maintain secure passwords without compromising usability.
Multi-Factor Authentication (MFA)
MFA adds an extra layer of security by requiring additional verification methods, such as biometrics or one-time passcodes. This significantly reduces the risk of unauthorized access, even if passwords are compromised.
Token-Based Access
Token-based access systems, such as OAuth, enhance security by providing temporary, limited access tokens instead of permanent credentials. This minimizes the exposure of sensitive information and improves control over access permissions.
Patch Repository
Regular updates and patches are crucial for mitigating vulnerabilities. A centralized patch repository allows enterprises to manage and deploy patches efficiently, ensuring that all devices remain up-to-date with the latest security fixes.
Firmware Over-the-Air (FOTA)
FOTA updates enable enterprises to remotely manage and update device firmware. This ensures that devices are protected against newly discovered vulnerabilities and can benefit from the latest performance enhancements.
Remote Wipe
In the event of a lost or stolen device, remote wipe capabilities allow enterprises to erase all data, minimizing the risk of data breaches. This function is essential for protecting sensitive information stored on mobile devices.
WiFi Security
- WiFi Protected Access (WPA2/3): WPA2/3 provides robust encryption for wireless networks, preventing unauthorized access and eavesdropping. Enterprises should enforce the use of WPA2/3 to secure their wireless communications.
- Device Certificates: Device certificates authenticate devices connecting to the network, ensuring that only trusted devices can access corporate resources.
Profiles
User profiles help manage device configurations based on user roles and permissions. Profile-based management allows enterprises to enforce security policies specific to different user groups, enhancing overall security.
Bluetooth and NFC
- Bluetooth: Secure Bluetooth configurations prevent unauthorized pairing and data transfer. Disabling discoverability and using strong pairing methods enhance Bluetooth security.
- Near-Field Communication (NFC): NFC security involves restricting NFC usage to authorized applications and disabling it when not needed to prevent unauthorized data exchange.
Peripherals
Managing peripherals involves controlling access to external devices like USB drives. Enterprises should enforce policies that restrict the use of unauthorized peripherals, reducing the risk of data leakage.
Geofencing
Geofencing creates virtual boundaries around specific geographic areas. It enables enterprises to enforce policies based on location, such as restricting access to sensitive data outside corporate premises.
VPN Settings
Virtual Private Networks (VPNs) provide secure remote access to corporate networks. Enforcing the use of VPNs for remote connections ensures encrypted data transmission, protecting sensitive information from interception.
Geotagging
Geotagging associates location information with data. Enterprises should manage geotagging settings to protect location-sensitive information and comply with privacy regulations.
Certificate Management
Certificate management involves issuing, renewing, and revoking digital certificates used for authentication and encryption. A robust certificate management system ensures secure communication and device authentication.
Full Device Encryption
Full device encryption protects data by encrypting all information stored on the device. This ensures that even if the device is compromised, the data remains inaccessible without proper decryption keys.
Tethering and Airplane Mode
- Tethering: Controlling tethering prevents unauthorized data sharing between devices. Enterprises should enforce policies that restrict tethering to secure devices.
- Airplane Mode: Managing airplane mode settings helps prevent unauthorized wireless communication by disabling all wireless connections when necessary.
Location Services
Location services management ensures that applications access location data only when necessary. Restricting location services helps protect user privacy and prevents unnecessary data exposure.
DNS over HTTPS (DoH) and Custom DNS
- DNS over HTTPS (DoH): DoH encrypts DNS queries, preventing interception and manipulation by third parties. Enforcing DoH enhances privacy and security for mobile devices.
- Custom DNS: Custom DNS settings allow enterprises to route DNS queries through secure servers, ensuring that domain name resolutions are handled securely.
Deployment Scenarios
Different deployment scenarios require tailored security strategies. This section explores various deployment models and their specific security considerations.
Bring Your Own Device (BYOD)
BYOD allows employees to use personal devices for work purposes. Security strategies for BYOD include implementing MDM (Mobile Device Management) solutions, enforcing secure app usage policies, and ensuring data segregation between personal and corporate data.
Corporate-Owned Devices
Corporate-owned devices provide greater control over security configurations. Enterprises can enforce stringent security policies, manage device settings centrally, and ensure compliance with organizational standards.
Corporate-Owned, Personally Enabled (COPE)
COPE combines the benefits of corporate-owned devices with personal usage flexibility. Enterprises should implement containerization to separate personal and corporate data, ensuring security without compromising user experience.
Choose Your Own Device (CYOD)
CYOD allows employees to choose from a selection of approved devices. Security configurations for CYOD involve enforcing policies on approved devices, ensuring compliance with security standards, and managing device updates.
Security Considerations
Secure configurations must address various security concerns. This section highlights critical security considerations for enterprise mobility.
Unauthorized Remote Activation/Deactivation
Preventing unauthorized activation or deactivation of devices or features is crucial. Enterprises should implement strong authentication mechanisms to control these actions.
Encrypted and Unencrypted Communication
Ensuring that all communication is encrypted protects data in transit from interception. Enterprises should enforce the use of encrypted communication channels and avoid unencrypted methods.
Physical Reconnaissance and Personal Data Theft
Physical security measures, such as device locking mechanisms and secure storage, help prevent unauthorized access to devices and data theft. Educating users about the risks of physical reconnaissance enhances security awareness.
Health Privacy and Wearable Devices
Wearable devices often collect sensitive health data. Enterprises should enforce strict privacy policies for wearable devices, ensuring that health data is protected and used in compliance with regulations.
Digital Forensics
Digital forensics capabilities enable enterprises to analyze collected data for security incidents. Implementing secure logging and audit trails ensures that forensic analysis can be conducted effectively.
Unauthorized Application Stores and Jailbreaking/Rooting
Preventing access to unauthorized application stores and detecting jailbroken or rooted devices help mitigate security risks. Enterprises should enforce policies that restrict the installation of unapproved apps and detect compromised devices.
Side Loading and Containerization
Controlling side loading prevents the installation of apps from untrusted sources. Containerization isolates corporate data from personal data, enhancing security and compliance.
