Cybersecurity Prologue Introduction and Latest MCQs

What is CyberSecurity?

Cyber Security is a process that’s designed to protect networks and devices from external threats. Businesses typically employ Cyber Security professionals to protect their confidential information, maintain employee productivity, and enhance customer confidence in products and services.

The world of Cyber Security revolves around the industry standard of confidentiality, integrity, and availability, or CIA. Privacy means data can be accessed only by authorized parties; integrity means information can be added, altered, or removed only by authorized users; and availability means systems, functions, and data must be available on-demand according to agreed-upon parameters.

The main element of Cyber Security is the use of authentication mechanisms. For example, a user name identifies an account that a user wants to access, while a password is a mechanism that proves the user is who he claims to be.

What are the types of Cyber Crimes?

Cybercriminals usually try to profit off of their crimes using a variety of tactics, including:

  • Denial of Service, or DOSWhere a hacker consumes all of a server’s resources, so there’s nothing for legitimate users to access
  • Malware Where victims are hit with a worm or virus that renders their devices useless
  • Man in the Middle Where a hacker puts himself between a victim’s machine and a router to sniff data packets
  • Phishing Where a hacker sends a seemingly legitimate-looking email asking users to disclose personal information

Other types of cyberattacks include cross-site scripting attacks, password attacks, eavesdropping attacks (which can also be physical), SQL-injection attacks, and birthday attacks based on algorithm functions.
