2.9 SoHO Networks Flashcards
What is the first step in configuring security settings on SOHO networks?
Change default passwords
This is crucial to prevent unauthorized access. Myst physically place router and manage ip address
What is IP filtering used for in network security?
To control which devices can access the network
This can help prevent unauthorized devices from connecting.
Why are firmware updates important for routers?
They fix vulnerabilities and improve performance
Regular updates help maintain security.
What is content filtering?
Blocking access to specific websites or content
This can protect users from harmful or inappropriate material.
What is a recommended physical security measure for routers?
Place routers in secure locations
This prevents tampering and unauthorized access.
What is the purpose of DHCP reservations?
To assign fixed IP addresses to specific devices
This ensures consistent network access for important devices.
What is a static WAN IP?
A fixed IP address assigned to a network
It is used for consistent external access.
What does disabling Universal Plug and Play (UPnP) do?
Prevents automatic port forwarding and device discovery
This enhances security by limiting network exposure.
What is the purpose of changing the SSID?
To hide the network’s identity from potential attackers
A unique SSID can deter casual intruders.
What does disabling SSID broadcast achieve?
Prevents the network from being visible to nearby devices
This makes it harder for unauthorized users to find the network.
What is the role of encryption settings?
To secure data transmitted over the network
Encryption protects information from interception.
Why should guest access be disabled?
To limit unauthorized access to the main network
This helps protect sensitive information on personal devices.
What is the purpose of changing wireless channels?
To reduce interference from other networks
This can improve network performance and reliability.
What are firewall settings used for?
To control incoming and outgoing network traffic
Firewalls protect the network from unauthorized access.
What is the importance of disabling unused ports?
To reduce potential entry points for attackers
Keeping only necessary ports open enhances security.
What is port forwarding/mapping?
Redirecting traffic from one port to another on a device
This is often used for services like gaming or remote access.
