# Security Protocols

Security is at the heart of GCB’s operations, particularly in the volatile environment of cryptocurrency.

###  Key Security Measures:

* Multi-Factor Authentication (MFA): Requires multiple authentication methods to protect user accounts.
* Encryption: End-to-end encryption for sensitive data both in transit and at rest.
* Smart Contracts: Audited and secure smart contracts to avoid vulnerabilities.
* DDoS Protection: Technologies to guard against Distributed Denial of Service attacks, ensuring the platform's availability.
* KYC/AML Procedures: Strict adherence to Know Your Customer (KYC) and Anti-Money Laundering (AML) protocols to prevent fraud.  
* Penetration Testing: Regular security audits and penetration tests to identify vulnerabilities before they can be exploited.
