Essential Security Practices for Computing Resources

🧩 4.1 Security Administration on Computing Resources

🔹 Secure Baselines

  • Define secure configurations (disable unused ports, enforce strong passwords, patch systems).

  • Deploy via configuration tools (Group Policy, Ansible, SCCM).

  • Maintain through regular audits and updates.

🔹 System Hardening

TargetKey Techniques
Workstations/ServersDisable Telnet/FTP; patch OS/apps; use AV + firewall; limit admin privileges.
Mobile DevicesUse MDM, enforce encryption, PIN/biometrics, remote wipe, containerization.

Early Earth Life Origins and Biological Classification

Part 5: Early Earth, Origin of Life, and Evolution

Characteristics of Early Earth & Prebiotic Simulation

Early Earth lacked oxygen and an ozone layer, resulting in high UV radiation, noxious gases, frequent electrical storms, and abundant water.

The prebiotic simulation (1950s) recreated these early Earth conditions in the lab, leading to the formation of amino acids—the basic building blocks of life. This supports the chemical evolution hypothesis.

Hypotheses for the Origin of Life

Factors Determining Economic Productivity and Output

Factors Determining Economic Productivity

An increase in the capital-to-labor ratio (K/L) causes an increase in output per worker (Y/L).

How Productivity Is Determined – Part 1

  • Natural Resources (N)
    • Inputs into production that nature provides (land, rivers, and mineral deposits).
  • Natural Resources per Worker (N/L)
    • Other things equal, more natural resources allow a country to produce more output (Y).
    • An increase in N/L causes an increase in Y/L.

How Productivity Is Determined – Part 2

  • Technological Knowledge
