Encryption is a key component of cloud web security. It scrambles data to make it unreadable to unauthorized parties. This ensures the confidentiality of sensitive information.

Firewalls are used to block malicious traffic from entering the network. They act as a barrier between the internal network and the external world, preventing cyber - attacks.

Intrusion detection systems monitor network activity for any signs of intrusion. They can detect and alert administrators to potential threats in real - time.

User authentication and access control are crucial. Multi - factor authentication provides an extra layer of security to prevent unauthorized access to cloud resources.
