    Study Notes

    Introduction to Networks

    • Networks are vital for interaction, learning, work, and play.
    • Networks have evolved from separate, dedicated networks to converged networks.
    • A Converged network carries multiple services (data, voice, video) on a single link.

    Network Requirements

    • There are four main requirements of a reliable network:
      • Fault Tolerance: Restricting impact of failures.
      • Scalability: Growing with an increasing number of users and devices.
      • Quality of Service (QoS): Providing a consistent level of performance to each application and user.
      • Security: Confidentially, Integrity, and Availability.
    • Bring Your Own Device (BYOD): Users connect to the network using their own devices.
    • Cloud Computing: Allowing for scalability and flexibility.
    • Video Communications: Replacing traditional voice calling.
    • Online Collaboration: Enabling teams to work together from anywhere.

    Security Threats

    • Security threats can be Internal or External.
    • External threats: Viruses, worms, Trojan horses, spyware, adware, zero-day attacks, hacker attacks, denial of service attacks, data interception and theft, identify theft.
    • Internal threats: User error
    • BYOD increases corporate data vulnerability.
    • Security Solutions;
      • Antivirus and antispyware software.
      • Firewalls.
    • Security is implemented in multiple layers using more than one security solution.
