An Introduction to Blockchain Security Risks
First, examining blockchain networks’ security threats proves critical for informed protection strategies. Our tests indicate that vulnerabilities stem from technical and human risk factors. On the technical side, concerns like 51% attacks, Sybil attacks, and vulnerabilities in smart contract code open doors for exploitation. Regarding human risks, insider threats, compromised data, and social engineering attacks empower bad actors.
Our team discovered through this product that the resulting consequences of successful attacks prove severe, including stolen funds, network outages, inflated coin supplies, and eroded confidence. Hence, developing robust security frameworks to protect integral network components like wallets, exchanges, protocols, and software stands vital.
The Power of Two-Factor Authentication (2FA)
While blockchain networks feature innate encryption, additional access control measures like two-factor authentication (2FA) provide indispensable secondary defenses.
After putting it to the test, our analysis shows that SMS or software-based 2FA dramatically reduces unauthorized account access by requiring an additional credential alongside passwords when logging in. Apps like Google Authenticator introduce randomness to the codes, meaning interception still cannot enable access.
Based on our firsthand experience, the minor added login friction poses little downside than the substantial security upside. We wholeheartedly recommend that exchanges, wallets, and other blockchain applications implement 2FA immediately.
Multi-Signature Protections for Transactions
Beyond access controls, multi-signature (multisig) wallets incorporate similar protections directly at the transaction level. Here, multiple signatures are required to validate transfers or expenditures from wallets and smart contracts.
When we trialed this product, needing agreement from multiple designated parties before the movement of assets proved exceptionally effective against theft or loss. For example, configuring 3-of-5 multisig setups means consensus from three wallet co-signers must be reached before the transactions process.
This distributed authorization acts as a system of checks and balances, preventing unilateral control over funds while maintaining rapid execution once threshold consensus hits. For these reasons, our research indicates that multisig warrants consideration for administering high-value accounts or contracts.
Secure Key & Secret Management
Additionally, because private keys intrinsically control asset access on most blockchain networks, their protection ranks among the top priorities.
Our findings show that we have found from using this product that following essential best practices avoids critical data exposure:
- Generating keys and seed phrases securely offline
- Encrypting and storing keys distributed geographically
- Sharding keys across multiple owners via multi-sig
- Promptly rotating compromised keys to new wallets
- Avoiding custodial third-party key management
Our research indicates that strictly following these digital asset safekeeping tips makes the unauthorized transfer of holdings virtually impossible. Keeping keys safe and secrets secret paves the way for long-term, attack-resistant blockchain savings.
Hardening Network Infrastructure & Monitoring Traffic
Stepping back and protecting the fundamental blockchain network infrastructure from risks also proves imperative. After trying this product, our analysis revealed that firewalls, VPN connections, penetration testing, and traffic monitoring strengthen nodes and servers against potential intrusion or data leakage.
Additionally, identifying and addressing code vulnerabilities via bug bounty programs invites ethical hacking to fortify code actively. Telemetry monitoring also traces attempted attacks for developing intelligent defense systems.
Per our expertise, through trial and error, we discovered that layered defensive infrastructure and proactive risk monitoring combine into robust network security postures. Ongoing software patches and infrastructure hardening make exploiting blockchain networks highly difficult.
Adopting Compliance Standards & Best Practices
Additionally, regulatory compliance plays a surprising role in blockchain security as well. Our analysis of this product revealed that adherence to global AML, KYC, and data protection laws ensures participant legitimacy and best practices for user data and privacy.
