100-160 Question 67
Single answerDuring a security audit of a company's network, the cybersecurity technician discovers that an internal server is using a public IP address instead of a private IP address. How could this configuration impact the organization's network security?
- A
It allows devices outside the organization to directly access the server, increasing the risk of unauthorized access.
- B
It improves the server's performance by enabling direct communication with external devices.
- C
It ensures the server is isolated from external threats by preventing external communication.
- D
It reduces the likelihood of IP address conflicts within the internal network.
Show answer and explanation
Correct answer: A
Explanation
Assigning a public IP address to an internal server bypasses the protection provided by private IP addresses and network firewalls, exposing the server to external threats. Best practices dictate using private IP addresses for internal servers and employing Network Address Translation (NAT) for secure external communication.
- A. Correct.
Using a public IP address for an internal server makes it directly accessible from the internet, increasing the risk of unauthorized access or attacks.
- B. Incorrect.
Public IP addresses do not inherently improve performance. Instead, they expose the server to external threats, which can harm security.
- C. Incorrect.
Using a public IP address does not isolate the server from external threats; it does the opposite by making it more accessible to external attackers.
- D. Incorrect.
While using public IP addresses can reduce internal IP conflicts, this is not a recommended practice for internal servers due to the significant security risks it poses.
