Client Application Isolation in Web Browser

Overview

Client Application Isolation ensures that the UnoLock web application runs in a fully isolated environment within the user's browser, providing additional layers of protection. This feature prevents the web application from interacting with other browser processes or tabs, reducing the risk of cross-site attacks, such as cross-site scripting (XSS) or man-in-the-middle (MITM) attacks. By containing the UnoLock client within a secure environment, this feature guarantees that sensitive operations, such as encryption and decryption, remain shielded from potential browser vulnerabilities or malicious extensions.

How It Works

  • Sandboxed Environment: UnoLock runs in a secure, sandboxed browser environment, separating its processes from other open tabs or extensions. This minimizes exposure to threats arising from other web applications.
  • Process Isolation: The browser allocates a separate process to UnoLock, preventing data leakage or cross-interaction with other browser processes.
  • Secure Handling of Data: All cryptographic functions (e.g., key generation, encryption) are handled locally and within the isolated browser context, ensuring that no sensitive data is shared across browser processes or with external websites.
  • Content Security Policy (CSP): UnoLock enforces a strict CSP to limit the sources of executable scripts, reducing the risk of XSS and other injection-based attacks.

Security Implications

  • Reduced Attack Surface: By isolating the UnoLock client within its own browser environment, the risk of browser-based attacks, such as cross-site scripting or unauthorized data access, is significantly reduced.
  • Protection Against Malicious Extensions: Browser extensions are prevented from accessing the UnoLock application or interacting with its data, enhancing the overall security of the platform.
  • Secure Local Operations: All sensitive operations (such as encryption and key management) are performed locally within the isolated context, reducing exposure to browser vulnerabilities.

Use Cases

  • Web-Based Vault Access: Users accessing their UnoLock vault through a web browser can securely manage their digital assets, knowing that their session is isolated from other websites and browser activities.
  • High-Security Environments: Individuals in sensitive roles (e.g., executives, journalists) who require strong browser isolation can benefit from additional protection against web-based attacks.
  • Cross-Platform Use: Users accessing UnoLock from different devices can rely on consistent security, thanks to the isolated client environment across all web browsers.

Why It Matters

Client Application Isolation ensures that sensitive operations and data within the UnoLock vault are protected from common browser vulnerabilities. In a world where phishing, malware, and browser-based exploits are rampant, isolating the UnoLock client reduces the risk of unauthorized access and ensures secure vault management.

FAQs

Can browser extensions interact with my UnoLock session?

No, UnoLock’s Client Application Isolation prevents browser extensions from interacting with your vault or accessing sensitive data.

How does this isolation protect my data?

By running in a sandboxed environment, UnoLock isolates its processes from the rest of the browser, ensuring that no data leaks occur and no unauthorized access is possible.

What happens if another website tries to access my UnoLock session?

The isolation prevents any cross-site interaction, ensuring that no other websites or browser tabs can access your UnoLock vault or session data.

Compliance & Privacy Regulations

  • GDPR & HIPAA Compliance: By ensuring secure data handling within an isolated browser context, Client Application Isolation helps users comply with strict data privacy regulations such as GDPR and HIPAA.

Integration with Other Features

  • Content Security Policy (CSP) Isolation: Works in conjunction with strict CSP enforcement to further limit potential attack vectors within the browser.
  • Client-Side Encryption: All cryptographic operations are securely handled within the isolated environment, ensuring end-to-end encryption integrity.
