- A.
Inbound HTTP traffic
- B.
Outbound HTTP traffic
- C.
Inbound HTTPS traffic
- D.
Outbound HTTPS traffic
Correct Answer
B. Outbound HTTP trafficExplanation
If a firewall is configured to block egress traffic on TCP ports 80, it means that any outgoing traffic on port 80, which is used for HTTP communication, will be blocked. This would affect the Outbound HTTP traffic, as any requests or data being sent from the local network to external servers using HTTP would not be able to pass through the firewall. However, it would not affect the Inbound HTTP traffic, Inbound HTTPS traffic, or Outbound HTTPS traffic, as these use different ports (80 for HTTP and 443 for HTTPS) which are not being blocked by the firewall in this scenario.Rate this question:

SSL encryption is a security protocol that encrypts the data transmitted between a web server and a web browser, ensuring that the information remains confidential and cannot be intercepted by unauthorized parties. By using SSL encryption, the HR department can protect the confidentiality of the data when employees enroll in benefits through the web site on the corporate Intranet. This encryption technology prevents hackers or eavesdroppers from accessing and understanding the sensitive information being transmitted.Rate this question:

Inadequate programming and coding practices introduce the risk of:
- A.
Phishing
- B.
Buffer overflow exploitation
- C.
SYN flood
- D.
Brute force attacks
Correct Answer
B. Buffer overflow exploitationExplanation
Inadequate programming and coding practices can lead to buffer overflow exploitation. This occurs when a program or system does not properly check the size of input data, allowing an attacker to overflow a buffer and overwrite adjacent memory. This can result in the execution of malicious code, unauthorized access to sensitive information, or system crashes. It is important to follow secure coding practices and validate input data to prevent buffer overflow vulnerabilities.Rate this question:

To prevent IP spoofing attacks, a firewall should be configured to drop a packet if:
- A.
The source routing field is enabled
- B.
It has a broadcast address in the destination field
- C.
A reset flag (RST) is turned on for the TCP connection
- D.
Dynamic routing is used instead of static routing
Correct Answer
A. The source routing field is enabledExplanation
If the source routing field is enabled, it allows the sender of a packet to specify the route that the packet should take through the network. This can be exploited by an attacker to spoof their IP address and bypass security measures. Therefore, to prevent IP spoofing attacks, a firewall should be configured to drop any packet that has the source routing field enabled.Rate this question:

An organization can ensure that the recipients of e-mails from its employees can authenticate the identity of the sender by:
- A.
Digitally signing all e-mail messages
- B.
Encrypting all e-mail messages
- C.
Compressing all e-mail messages
- D.
Password protecting all e-mail messages
Correct Answer
A. Digitally signing all e-mail messagesExplanation
By digitally signing all e-mail messages, an organization can ensure that the recipients can authenticate the identity of the sender. Digital signatures use encryption technology to verify the integrity and authenticity of the message. The sender's digital signature is unique to them and can only be generated with their private key. When the recipient receives the digitally signed message, they can use the sender's public key to verify the signature and confirm that the message has not been tampered with and indeed originated from the claimed sender. This provides a level of trust and assurance in the authenticity of the e-mail.Rate this question:

The use of residual biometric information to gain unauthorized access is an example of which of the following attacks:
- A.
Mimic
- B.
Brute force
- C.
Cryptographic
- D.
Replay
Correct Answer
D. ReplayExplanation
The use of residual biometric information to gain unauthorized access is an example of a replay attack. In a replay attack, an attacker intercepts and records legitimate data or information and then replays it later to gain unauthorized access. In this case, the residual biometric information, such as fingerprints or facial recognition data, is captured and replayed to bypass the biometric authentication system and gain unauthorized access.Rate this question:

Use the diagram to answer this question. To detect attack attempts that the firewall is unable to recognize, an IS auditor should recommend placing a network intrusion detection system (IDS) between the:
- A.
Firewall and the organization's network
- B.
Internet and the firewall
- C.
Internet and the web server
- D.
Web server and the firewall
Correct Answer
A. Firewall and the organization's networkExplanation
An IS auditor should recommend placing a network intrusion detection system (IDS) between the firewall and the organization's network. This is because the IDS is designed to detect and monitor network traffic for any suspicious or malicious activity that the firewall may not be able to recognize. By placing the IDS in this location, it can analyze the incoming and outgoing traffic and alert the organization of any potential attack attempts that the firewall may have missed. This helps to enhance the overall security of the network and protect against unrecognized threats.Rate this question:

Use the diagram to answer this question. E-mail traffic from the Internet is routed via firewall-1 to the mail gateway. Mail is routed from the mail gateway. via firewall-2, to the mail recipients in the internal network. Other traffic is not allowed. For example, the firewalls do not allow direct traffic from the Internet to the internal network. The intrusion detection system (IDS) detects traffic for the internal network that did not originate form the mail gateway. The first action triggered by the IDS should be to:
- A.
Alert the appropriate staff
- B.
Create an entry in the log
- C.
Close firewall-2
- D.
Close firewall-1
Correct Answer
C. Close firewall-2Explanation
The correct answer is to close firewall-2 because the intrusion detection system (IDS) has detected traffic for the internal network that did not originate from the mail gateway. By closing firewall-2, it prevents any further unauthorized traffic from entering the internal network, ensuring the security and integrity of the network.Rate this question:
