Distributed Denial of Service attack. Spam a web server with so many requests so close together that it crashes. Sometimes spitting out valuable information as it crashes.
Protocols for encrypting/decrypting information. Most cybersecurity breaches happen due to human error, not software bugs.
The usage of deceptive emails and websites to maliciously gather personal information
Examples of servers include web servers, mail servers, and file servers. Each of these servers provide resources to client devices. Most servers have a one-to-many relationship with clients, meaning a single server can provide multiple resources to multiple clients at one time.
Confirms the identity and authenticity of a website.
sequential programming refers to programs that are executed sequentially – once through, from start to finish, without other processing executing.
