INSTRUCTIONS:
Click on the firewall and configure it to allow ONLY the following communication.

Section: Network Security
Implicit deny is the default security stance that says if you aren't specifically granted access or privileges for a resource, you're denied access by default.Rule #1 allows the Accounting workstation to ONLY access the web server on the public network over the default HTTPS port, which is TCP port 443.Rule #2 allows the HR workstation to ONLY communicate with the Financial server over the default SCP port, which is TCP Port
22Rule #3 & Rule #4 allow the Admin workstation to ONLY access the Financial and Purchasing servers located on the secure network over the default TFTP port, which is Port 69.

NEW QUESTION # 369
Task: Configure the firewall (fill out the table) to allow these four rules:
Only allow the Accounting computer to have HTTPS access to the Administrative server.
Only allow the HR computer to be able to communicate with the Server 2 System over SCP.
Allow the IT computer to have access to both the Administrative Server 1 and Administrative Server CORRECT TEXT Task: Configure the firewall (fill out the table) to allow these four rules:
Only allow the Accounting computer to have HTTPS access to the Administrative server.
Only allow the HR computer to be able to communicate with the Server 2 System over SCP.
Allow the IT computer to have access to both the Administrative Server 1 and Administrative Server 2
- A. Use the following answer for this simulation task.
Below table has all the answers required for this question.
Firewall rules act like ACLs, and they are used to dictate what traffic can pass between the firewall and the internal network. Three possible actions can be taken based on the rule's criteria:
Block the connection Allow the connection
Allow the connection only if it is secured
TCP is responsible for providing a reliable, one-to-one, connection-oriented session. TCP establishes a connection and ensures that the other end receives any packets sent.
Two hosts communicate packet results with each other. TCP also ensures that packets are decoded and sequenced properly. This connection is persistent during the session.
When the session ends, the connection is torn down.
UDP provides an unreliable connectionless communication method between hosts. UDP is considered a best-effort protocol, but it's considerably faster than TCP.
The sessions don't establish a synchronized session like the kind used in TCP, and UDP doesn't guarantee error-free communications.
The primary purpose of UDP is to send small packets of information.
The application is responsible for acknowledging the correct reception of the data. Port 22 is used by both SSH and SCP with UDP.
Port 443 is used for secure web connections? HTTPS and is a TCP port.
Thus to make sure only the Accounting computer has HTTPS access to the Administrative server you should use TCP port 443 and set the rule to allow communication between 10.4.255.10/24 (Accounting) and 10.4.255.101 (Administrative server1) Thus to make sure that only the HR computer has access to Server2 over SCP you need use of TCP port 22 and set the rule to allow communication between 10.4.255.10/23 (HR) and 10.4.255.2 (server2) Thus to make sure that the IT computer can access both the Administrative servers you need to use a port and accompanying port number and set the rule to allow communication between: 10.4.255.10.25 (IT computer) and 10.4.255.101 (Administrative server1)
10.4.255.10.25 (IT computer) and 10.4.255.102 (Administrative server2) - B. Use the following answer for this simulation task.

An analyst wants to implement a more secure wireless authentication for office access points. Which of the
following technologies allows for encrypted authentication of wireless clients over TLS?
- A. WPA2
- B. PEAP
- C. RADIUS
- D. EAP
Answer: B
Explanation:
Explanation/Reference:
Explanation:
EAP by itself is only an authentication framework.
PEAP (Protected Extensible Authentication Protocol) fully encapsulates EAP and is designed to work
within a TLS (Transport Layer Security) tunnel that may be encrypted but is authenticated. The primary
motivation behind the creation of PEAP was to help correct the deficiencies discovered within EAP since
that protocol assumes that the communications channel is protected. As a result, when EAP messages are
able to be discovered in the "clear" they do not provide the protection that was assumed when the protocol
was originally authored.
PEAP, EAP-TTLS, and EAP-TLS "protect" inner EAP authentication within SSL/TLS sessions.
