Set Up Ip Addressing
Setting up IP addressing is key for network communication. Every device needs a unique IP address.
This setup helps devices find each other and share data smoothly. Proper addressing avoids conflicts.
Assign Static And Dynamic Ips
Static IPs do not change and stay assigned to a device. They are useful for servers and printers.
Dynamic IPs change over time and are given by a DHCP server. They work well for most user devices.
- Use static IPs for important devices that need a fixed address
- Use dynamic IPs for everyday devices like laptops and phones
- Keep a list of static IP addresses to avoid conflicts
Configure Subnets
Subnets divide a large network into smaller parts. This helps organize and manage traffic better.
Each subnet has its own range of IP addresses. Devices in the same subnet communicate faster.
- Choose subnet masks based on the number of devices
- Use smaller subnets to improve security and reduce traffic
- Plan subnets to match departments or locations
Implement Dhcp Settings
DHCP automatically assigns IP addresses to devices on a network. It saves time and reduces errors.
Set DHCP scopes to control which IPs can be assigned. You can also set lease times for addresses.
- Define IP address ranges for DHCP to use
- Set lease duration based on how long devices stay connected
- Reserve IP addresses for devices needing static assignment

Configure Network Protocols
Network protocols control how devices communicate. Setting them right keeps your network safe and fast.
Good protocol configuration stops attacks and improves data flow. Follow this checklist to secure your network.
Enable Secure Communication Protocols
Use secure protocols to protect data during transfer. They prevent eavesdropping and data theft.
Protocols like HTTPS, SSH, and TLS encrypt information. This keeps your network communications private and safe.
- Activate HTTPS for web traffic
- Use SSH for secure remote access
- Enable TLS for email and messaging
- Disable older, insecure protocols like Telnet
Disable Unused Services
Turning off unused services reduces security risks. Each active service can be a target for hackers.
Check all running services and stop those not needed. This lowers the chance of network breaches.
- List all active network services
- Identify services not in use
- Disable or uninstall those services
- Regularly review running services
Update Firmware And Software
Keep firmware and software up to date. Updates fix security holes and improve performance.
Check for updates from device makers often. Apply them quickly to protect your network.
- Schedule regular update checks
- Install firmware patches promptly
- Update network software frequently
- Test updates before full deployment
Implement Access Controls
Access controls protect your network from unwanted users. They help keep data safe and secure.
Strong access controls limit who can see or change important information. This lowers the risk of attacks.
Set Strong Passwords And Credentials
Use passwords that are hard to guess. Mix letters, numbers, and symbols for better security.
Change default passwords right away. Avoid using the same password for many accounts.
- Use at least 12 characters
- Include uppercase and lowercase letters
- Add numbers and special characters
- Change passwords every 3 to 6 months
Use Multi-factor Authentication
Multi-factor authentication adds a second step to login. This step can be a code or a fingerprint.
This extra step makes it harder for hackers to access accounts. Even if they have the password, they need more.
- Use SMS or email codes
- Use authentication apps like Google Authenticator
- Enable biometric checks if available
Define User Roles And Permissions
Assign roles to users based on their job tasks. This limits what each user can do.
Only give access needed to perform work. Avoid giving full control to everyone.
- Admin: Full access to all settings
- Editor: Can change content but not settings
- Viewer: Can see data but not edit
