Purposes of a plan
Verify that all business requirements will be met
Verify that all technical requirements will be met
Create a roadmap for network implementation
Document the network design for future use
Creating a plan
1. Determine business requirements
2. Review the current infrastructure
3. Review new and existing technologies
4. Determine the appropriate infrastructure requirements
5. Document the design
6. Review the documentation with the appropriate personnel
Ongoing planning
Plans evolve New technologies emerge
Implementing a plan
1. Purchase equipment
2. Install network media
3. Connect your networking devices
4. Connect your computers
Wireless LAN components
Wireless NICs Wireless access points
Firewalls
Controls traffic Blocks or permits traffic based on
rules
NAT
Correlates internal and external addresses
Protects internal devices Reasons for NAT
– Availability of addresses– Security
Port address translation
NAT services using port numbers Port triggering
Security zones
Intranet Perimeter DMZs
