NEW QUESTION # 144
Which of the following are potential risks in HTTP communication?

A. Lost: There is a low probability that data is lost during transmission.
B. Pretending: Third parties can impersonate another user.
C. Tampering: Third parties can tamper with communication data.
D. Eavesdropping: Third parties can obtain communication data.

Answer: B,C,D

Explanation:
Understanding HTTP Security Risks
# What is HTTP?
* HTTP (Hypertext Transfer Protocol) is a protocol used for communication between web clients (browsers) and servers.
* It is unencrypted, making it vulnerable to security threats.
Potential Risks in HTTP Communication:
# A. Eavesdropping (Data Interception)
* Correct: HTTP traffic is unencrypted, meaning attackers can capture data using tools like Wireshark or MITM (Man-in-the-Middle) attacks.
* Example: Hackers intercept login credentials over public Wi-Fi.
# B. Pretending (Impersonation / Spoofing)
* Correct: Without encryption or authentication, attackers can spoof legitimate websites.
* Example: A phishing website mimics a banking login page to steal user credentials.
# C. Tampering (Data Manipulation)
* Correct: Attackers can modify HTTP data in transit, changing the content sent to users.
* Example: Injecting malicious scripts into a webpage (e.g., Cross-Site Scripting - XSS).
# D. Lost (Low Probability of Data Loss)
* Incorrect: HTTP runs over TCP, which ensures reliable data transmission.
* Packet loss is not a major security risk but rather a network performance issue.
How to Mitigate HTTP Risks?
* Use HTTPS (HTTP Secure) # Encrypts data using TLS (Transport Layer Security).
* Enable HSTS (HTTP Strict Transport Security) # Forces HTTPS connections.
* Implement Web Application Firewalls (WAFs) # Protects against attacks like SQL Injection & XSS.
