Network Trends:1. Bring Your Own Device (BYOD) allows users to access information and communicate using their own devices.2. Online Collaboration enables collaboration over the network on joint projects.3. Video Communication allows video calls to be made to anyone, regardless of location, using tools like Cisco TelePresence.4. Cloud Computing allows businesses to store personal files or backup data on servers over the internet and access applications through the cloud.5. Smart Home Technology integrates technology into everyday appliances to interconnect them.6. Powerline Networking allows devices to connect to a LAN using electrical outlets and standard powerline adapters.7. Wireless Broadband provides an alternative to DSL and cable internet connectivity in rural areas through wireless internet service providers (WISPs).Security Threats:1. Network Security is essential for protecting data, regardless of network size, using protocols, technologies, devices, tools, and techniques.2. External Threats include viruses, worms, Trojan horses, threat actor attacks, denial-of-service (DoS) attacks, data interception, and identity theft.3. Internal Threats include lost or stolen devices, accidental misuse by employees, malicious employees, etc.Security Solutions:1. Install antivirus and antispyware software on end devices to protect against viruses, worms, Trojan horses, spyware, and adware.2. Use firewall filtering to block unauthorized access to the network.3. Implement dedicated firewall systems, access control lists (ACLs), intrusion prevention systems (IPS), and virtual private networks (VPNs) for larger networks.
