There are several methods to protect data from eavesdropping:
1. Encryption: Encrypting data makes it unreadable to anyone who doesn’t have the correct key. For example, Transport Layer Security (TLS) is a widely used encryption protocol that helps protect data from eavesdropping.
2. Network Segmentation: Network segmentation is a technique that divides a network into smaller, isolated parts. This limits the damage that can be done by an eavesdropper, as they can only access the segmented network they are connected to.
3. Firewalls: Firewalls are systems that control the flow of data into and out of a network. They can be used to block suspicious traffic and protect data from eavesdropping.
4. Access Control: Access control is a security measure that restricts access to certain resources. For example, a network administrator can limit access to sensitive data to only authorized users. This helps protect data from eavesdropping by unauthorized individuals.
