# Input Validation Strategy ⎊ Area ⎊ Greeks.live --- ## What is the Input of Input Validation Strategy? The core of robust systems across cryptocurrency, options, and derivatives hinges on rigorous input validation. This process acts as a primary defense against malicious actors and operational errors, ensuring data integrity before any computational step. Effective input validation minimizes the attack surface and prevents unexpected behavior stemming from malformed or unauthorized data. It’s a foundational element of secure and reliable trading infrastructure. ## What is the Strategy of Input Validation Strategy? A comprehensive input validation strategy involves a layered approach, encompassing both whitelist and blacklist techniques. Whitelisting defines acceptable inputs, rejecting anything outside that scope, while blacklisting identifies and blocks known malicious patterns. The specific strategy employed depends on the context; for example, smart contract code demands stringent whitelisting to prevent exploits, whereas order book validation might utilize a combination of both. Regular review and adaptation of the strategy are crucial to address evolving threats and market conditions. ## What is the Validation of Input Validation Strategy? Input validation in these complex financial environments extends beyond simple data type checks. It incorporates range constraints, format verification, and consistency checks across related fields. For instance, validating order sizes against account balances or ensuring timestamps adhere to market open/close times are critical. Furthermore, cryptographic validation, such as signature verification for on-chain transactions, is essential for maintaining trust and preventing unauthorized actions. --- ## [Input Sanitization in Proxies](https://term.greeks.live/definition/input-sanitization-in-proxies/) Process of validating and cleaning external data at the proxy level to prevent malicious input from reaching logic. ⎊ Definition ##
