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.
Network Trends
- 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.
