Crypto Exchange Security 10 Golden Rules - Detaylı rehber
Keep 90-95% of assets offline!
Hot Wallet (Online)
Cold Wallet (Offline)
1. Multi-signature cold wallets
2. Hardware wallets (Ledger, Trezor)
3. Air-gapped computers
4. Geographic distribution
5. Time-locked transfers
Binance approach:
95% cold storage
Multi-location cold wallets
Single signature is not enough!
For withdrawal, 2 of 3 people must approve:
- CEO signature
- CTO signature
- CFO signature
Advantage: One person cannot be hacked
Protect from attacks!
Layer 3-4 (Network)
Layer 7 (Application)
Two-Factor Authentication for everyone!
1. TOTP (Time-based OTP)
2. SMS (Risky!)
3. Hardware Tokens
1. Registration: 2FA mandatory
2. Login: 2FA check
3. Withdrawal: Email + 2FA
4. API key: 2FA required
5. Settings change: 2FA verify
For every critical operation!
# Withdrawal confirmation flow
1. User requests withdrawal
2. System sends email + SMS
3. User clicks link (30 min expiry)
4. 2FA verification
5. Withdrawal processed
Detect suspicious activities!
Detect:
1. Freeze account (automatic)
2. Send alert (email + SMS)
3. Require additional verification
4. Manual review queue
5. Risk scoring system
Test continuously!
1. Code Audit
2. Penetration Testing
3. Infrastructure Audit
Last line of defense!
Crypto Insurance
Self-Insurance (SAFU)
Biggest threat is from within!
Principle of Least Privilege
CEO: Strategy decisions
CTO: Technical access
CFO: Financial access
Developers: Code only
Support: User data (limited)
Multi-approval

Crypto exchange security is vital. 10 Golden Rules:
Security is not a cost, it's an investment! 🚀
The most important security rule is using cold wallets for 90-95% of assets. Cold wallets are offline and cannot be hacked remotely. This protects the majority of funds even if hot wallets are compromised. Multi-signature cold wallets add an extra layer of security.
Multi-signature requires multiple approvals for transactions, preventing single points of failure. If one person's credentials are compromised, funds remain safe. For example, a 2-of-3 MultiSig requires 2 out of 3 authorized persons to approve withdrawals.
DDoS (Distributed Denial of Service) attacks overwhelm servers with traffic, making exchanges unavailable. Exchanges need DDoS protection because downtime means lost revenue and user trust. Layered protection at network (Layer 3-4) and application (Layer 7) levels is essential.
2FA (Two-Factor Authentication) adds a second verification step beyond passwords, significantly reducing account compromise risk. Even if passwords are stolen, attackers cannot access accounts without the 2FA code. TOTP apps (Google Authenticator) are more secure than SMS.
Anomaly detection uses machine learning to identify suspicious activities like unusual withdrawal amounts, logins from new locations, or abnormal trading patterns. When anomalies are detected, accounts can be automatically frozen and alerts sent for manual review.
Crypto exchanges should perform code audits (smart contract review, vulnerability scanning), penetration testing (quarterly white hat hacking), and infrastructure audits (server configuration, SSL/TLS verification). Regular audits help identify and fix vulnerabilities before attackers exploit them.
Insurance coverage depends on exchange size and risk profile. Major exchanges typically have $100M-$1B in coverage. Self-insurance through SAFU funds (10% of trading fees) provides additional protection. Insurance should cover hot wallet hacks, internal theft, and operational errors.
The biggest security threat is often internal - employees with excessive access or malicious insiders. Implementing principle of least privilege, multi-approval processes, background checks, and access controls minimizes internal security risks.
Security audits should be performed quarterly for penetration testing, annually for comprehensive audits, and continuously for code reviews. After major updates or security incidents, immediate audits are recommended. Regular audits are essential for maintaining security.
Users should enable 2FA, use strong unique passwords, enable email/SMS confirmations for withdrawals, use whitelisted withdrawal addresses, avoid phishing scams, never share credentials, and use hardware wallets for large amounts. User education is crucial for overall security.
