In the world of cybersecurity, we often talk about encryption, access controls, and authentication. But there’s a critical vulnerability that many organizations overlook: the concentration of power in individual administrators. PreVeil’s Approval Groups offer an innovative solution to this problem, fundamentally changing how we approach administrative security.

Understanding PreVeil's Approval Groups

The Problem with Traditional Admin Access

Imagine giving one person the keys to every room in a building. No matter how trustworthy that person is, it creates a single point of failure. If their keys are stolen or they turn malicious, the entire building is compromised. This is exactly how traditional admin access works in most systems – administrators have complete access to reset passwords, access user data, and make system-wide changes.

Enter Approval Groups

PreVeil’s Approval Groups take a radically different approach. Instead of giving complete power to individual administrators, they require multiple people to approve sensitive operations. Think of it like a bank vault that requires two different keys to open, held by two different people.

How Approval Groups Work

PreVeil implements Approval Groups using a clever cryptographic technique called Shamir Secret Sharing. Here’s how it works:

  1. Key Splitting: Instead of giving complete access to any individual, a secret key is split into multiple pieces (“shards”)
  2. Distributed Trust: Each shard is encrypted and given to a different approver
  3. Threshold Requirements: The system is configured to require a specific number of approvers (e.g., “any 3 out of 5”)
  4. Secure Reconstruction: When approval is needed, the required number of approvers must provide their shards to reconstruct the key

Real-World Applications

Approval Groups in PreVeil are used for several critical functions:

1. Account Recovery

  • If a user loses access to their device, they can recover their account
  • Multiple approvers must participate in the recovery process
  • No single administrator can access a user’s data

2. Data Export

  • When organizations need to export data for compliance or e-discovery
  • Requires multiple approvers to authorize the export
  • Prevents unauthorized bulk data access

3. Administrative Actions

  • Adding or removing users
  • Changing security settings
  • Promoting users to administrators

The Benefits

1. Eliminated Single Points of Failure

  • No individual can compromise the system
  • Malicious insider threats are significantly reduced
  • Lost or stolen admin credentials aren’t catastrophic

2. Better Compliance

  • Creates natural separation of duties
  • Provides clear audit trails
  • Supports principle of least privilege

3. Enhanced Security Culture

  • Encourages collaborative security decisions
  • Reduces pressure on individual administrators
  • Creates mutual oversight

Technical Implementation

PreVeil’s implementation is particularly elegant because it:

  • Uses cryptographic methods rather than just policy controls
  • Operates without centralized key storage
  • Maintains end-to-end encryption throughout
  • Automatically rekeys after each use

A Critical Difference: Cryptographic Enforcement vs. Policy-Based Security


Most traditional systems rely on policy-based enforcement for access control, meaning administrators can override or modify access permissions. This creates an inherent security risk: if an admin is compromised, policies can be changed to grant unauthorized access.

PreVeil eliminates this risk by enforcing access security at the cryptographic level. Instead of relying on policies that can be circumvented, PreVeil’s Approval Groups ensure security is mathematically enforced. Even if an admin account is compromised, attackers cannot bypass the multi-party cryptographic approval process.

This is a fundamental shift: security isn’t just about trusting the right people—it’s about making unauthorized access impossible without explicit multi-party approval.

Setting Up Approval Groups

When configuring Approval Groups, organizations should consider:

  1. Group Size: How many total approvers should be in the group?
  2. Threshold: How many approvers are required for authorization?
  3. Member Selection: Who should be approvers? Consider:
    • Different departments
    • Various levels of authority
    • Geographic distribution

Best Practices

To get the most out of Approval Groups:

  1. Diverse Membership: Include approvers from different departments and roles
  2. Clear Procedures: Document when and how approvals should be requested
  3. Regular Reviews: Periodically review and update group membership
  4. Training: Ensure approvers understand their responsibilities
  5. Backup Plans: Have contingencies for when approvers are unavailable

Real-World Example

Let’s say an organization configures an Approval Group with five members requiring any three to approve sensitive operations. If an employee loses access to their account:

  1. The employee initiates account recovery
  2. The system notifies all five approvers
  3. Three or more approvers must securely provide their key shards
  4. The system reconstructs the necessary keys
  5. The account is recovered with new keys
  6. Old keys are automatically invalidated

Conclusion

PreVeil’s Approval Groups represent a fundamental shift in how we think about administrative access. By distributing trust across multiple individuals and enforcing it through cryptography rather than policy, they create a security system that’s both more robust and more practical.  

This approach recognizes that in today’s security landscape, it’s not enough to just encrypt data or control access. We need to think about how administrative power is distributed and controlled. Approval Groups provide a elegant solution to this challenge, offering organizations a way to maintain security without creating dangerous concentrations of power.

For organizations serious about security, Approval Groups aren’t just a feature – they’re a necessity. They represent the future of administrative access control, where security is built on distributed trust rather than individual power.
