Question

While reviewing a PCAP in Wireshark, an analyst follows an HTTP stream and sees the following server reply to a client GET request:

HTTP/1.1 200 OK
Date: Tue, 14 May 2024 09:22:41 GMT
Server: Apache/2.2.15 (CentOS)
X-Powered-By: PHP/5.3.3
Content-Type: text/html; charset=UTF-8
Content-Length: 4821

Which intrusion-analysis conclusion is BEST supported by interpreting these HTTP response header fields?

Accepted Answer

The response headers disclose specific server software and versions, giving an attacker reconnaissance data to match against known vulnerabilities.

Answer

The 200 OK status code confirms the server successfully blocked an exploitation attempt.

Answer

The Content-Length field indicates the payload was encrypted before transmission.

Answer

The Date header proves the client and server clocks are synchronized, ruling out a replay attack.
