Difficulty: EasyHost, Network, and Architecture Vulnerabilities

A system administrator discovers that a server in the data center is running an operating system version for which the vendor has permanently discontinued all technical support and security updates. Which of the following host vulnerabilities best describes this situation?

  1. End-of-life systemAnswer
  2. B
    Default credentials
  3. C
    SQL injection exposure
  4. D
    Missing perimeter firewall

Answer

End-of-life system
An end-of-life (EOL) system occurs when a software vendor ceases all support, maintenance, and security patch distribution for a product. When security flaws are discovered in EOL systems, vendors do not issue patches, creating persistent host vulnerabilities.

Step-by-Step Solution

1
Analyze the host condition presented in the scenario.
The server's operating system has reached a status where vendor patches and technical support have been permanently discontinued.
Identifying vendor support lifecycle milestones helps categorize the exact host vulnerability.
2
Match the observed condition to vulnerability taxonomy definitions.
Software or hardware no longer receiving vendor support or security patches is defined as an end-of-life (EOL) system.
EOL hosts present severe security risks because security flaws discovered after the support end date will remain unpatched.
