## What is the Integrity of Data Feed Security?

Data feed security ensures that external market information provided to smart contracts is accurate and tamper-proof. In decentralized finance, reliable price data is essential for accurate collateral valuation and derivative settlement. The integrity of these feeds prevents malicious actors from exploiting price discrepancies between exchanges.

## What is the Vulnerability of Data Feed Security?

Attack vectors often target data feeds through flash loans or oracle manipulation, where an attacker temporarily distorts the price on a single exchange. If a protocol relies on a single or poorly aggregated source, this manipulation can trigger incorrect liquidations or allow for profitable arbitrage at the expense of the protocol. The vulnerability of data feeds represents a critical systemic risk in DeFi.

## What is the Mitigation of Data Feed Security?

Mitigation strategies involve using decentralized oracle networks that aggregate data from multiple sources, making manipulation prohibitively expensive. Time-weighted average prices (TWAP) are also employed to smooth out short-term price spikes and reduce the impact of sudden market movements. These measures enhance the robustness of derivatives protocols against data-related exploits.
