How does a distributed denial-of-service (DDoS) attack work, and what measures can be taken to mitigate its impact?
A DDoS attack floods a target server or network with an overwhelming amount of traffic, causing service disruption. Mitigation measures include implementing rate limiting, traffic filtering, and using DDoS protection services.

See lessWhat are the differences between symmetric and asymmetric encryption algorithms, and when is each used?
Symmetric encryption uses a single key for both encryption and decryption, while asymmetric encryption uses a pair of keys (public and private). Symmetric encryption is faster and used for bulk data encryption, while asymmetric encryption is used for key exchange and digital signatures.

See lessWhat is the difference between HTTP and HTTPS, and why is HTTPS important for web security?
HTTPS encrypts data transmitted between a web server and a browser, while HTTP sends data in plain text. HTTPS is crucial for web security as it protects sensitive information from eavesdropping and interception by malicious actors.
