Lesson 4: Network Security

What does NAT do?

• It encrypts and authenticates IP packets.
• It provides caching and reduces network traffic.
• It translates public IP addresses to private addresses and vice versa.
• It analyzes incoming and outgoing traffic packets.

The WPA2 PreShared Key (PSK) is created by using a passphrase (password) and salting it with the WPS PIN.

• Service Set Identifier (SSID)
• Admin password
• WEP key
• No change is needed

To implement WPA2 Enterprise, you would need a/an:

• RADIUS server
• SSL server
• WEP server
• VPN server

What is a service set identifier (SSID)?

• A wireless encryption standard
• The wireless LAN transmission type
• The broadcast name of an access point
•  A wireless security protocol

What is a common method for password collection?

• Email attachments
• Back door intrusions
• SQL Injection
• Network sniffers

Which technology enables you to filter communications between a program and the Internet?

• RADIUS server
• Antivirus software
• Software firewall
• BitLocker To Go

The first line of defense against attacks from the Internet is a software firewall.

• hardware firewall
• virus software
• radius server
• No change is needed

Which type of firewall allows for inspection of all characteristics of a packet?

• NAT
• Stateful
• Stateless
• Windows Defender

Basic security questions used to reset a password are susceptible to:

• Hashing
• Social engineering
• Network sniffing
• Trojan horses

Network Access Protection (NAP) enables administrators to control access to network
resources based on a computer's:

• Encryption level
• Warranty
• Physical location
• Configuration
