DoS attack prevention involves measures taken to protect a network, system, or service from denial-of-service attacks. These attacks aim to overwhelm a network with excessive requests, making it unavailable to legitimate users.In cryptocurrency, these attacks can disrupt transactions and hinder the functioning of exchanges, wallets, and blockchain networks. To mitigate this risk, various strategies are employed.Rate limiting restricts the number of requests a user can make in a given timeframe, reducing the chances of an attack succeeding. Load balancing distributes incoming traffic across multiple servers, ensuring that no single server is overwhelmed by too many requests.Firewalls and intrusion detection systems help identify and block malicious traffic before it reaches critical systems. Additionally, decentralized networks inherently offer some resilience against DoS attacks, as there is no single point of failure. Combining these techniques helps ensure continuous availability of services and protects the integrity of cryptocurrency operations.
