Multi-layered defense refers to a security strategy that employs multiple layers of protection to safeguard assets, data, and transactions. In this context, it aims to protect against various threats such as hacking, fraud, and malware.The first layer typically involves secure wallets, including hardware and software options, to store funds safely. These wallets often require encryption and private keys to limit access.The second layer includes two-factor authentication (2FA) that adds an additional step for verifying user identity. This can involve using mobile apps or physical tokens.Another layer involves regular software updates to patch vulnerabilities in both wallets and exchanges. Additionally, employing strong, unique passwords further enhances security.Furthermore, transaction monitoring can act as a layer that detects and alerts users about suspicious activities. This helps in taking immediate action to protect assets.By using a multi-layered approach, individuals and organizations can reduce the risk of breaches and provide more robust security for their assets.
