Answer: A

"An application-level gateway is the best way to protect
against hacking because it can define with detail rules that
describe the type of user or connection that is, or is not
permitted. It analyzes in detail each package, not only in
layers one through four of the OSI model but also layers
five through seven, which means that it reviews the commands
of each higher level protocol (HTTP, FTP, SNMP, etc.) For a
remote access server there is a device (server) asking for
username and passwords before entering the network. This is
good when accessing private networks, but it can be mapped
or scanned from the Internet creating security exposure.
Proxy servers can provide protection based on the IP address
and ports. However, an individual is needed who really knows
how to do this, and second applications can use different
ports for the different sections of their program. Port
scanning works when there is a very specific task to do, but
not when trying to control what comes from the Internet (or
when all the ports available need to be controlled somehow).
For example, the port for "

Ping"

(echo request) could be blocked and the IP addresses would
be available for the application and browsing,

Answer / chatter

The Correct answer is A
A. An application-level gateway is the best way to protect against hacking because it can be configured with detailed rules that describe the type of user or connection that is or is not permitted. It analyzes, in detail, each package—not only in layers one through four of the Open System Interconnection (OSI) model, but also layers five through seven, which means that it reviews the commands of each higher-level protocol (Hypertext Transmission Protocol [HTTP], File Transfer Protocol [FTP], Simple Network Management Protocol [SNMP], etc.).
B. For a remote access server, there is a device (server) that asks for a username and password before entering the network. This is good when accessing private networks, but it can be mapped or scanned from the Internet, creating security exposure.
C. Proxy servers can provide excellent protection, but depending on the type of proxy, they may not be able to examine traffic as effectively as an application gateway. For proxy servers to work, an individual is needed who really knows how to do this, and applications can use different ports for the different sections of the program.
D. Port scanning is used to detect vulnerabilities or open ports on a network, but not when trying to control what comes from the Internet, or when all the ports available need to be controlled. For example, the port for Ping (echo request) could be blocked and the IP addresses would be available for the application and browsing but would not respond to Ping.
