QuestionQ72

Threat Intelligence in Incident Response

The following elements are included in the order of volatility for a typical computing system under the RFC 3227 evidence-collection and archiving guidelines:

  1. Archival media
  2. Remote logging and monitoring data related to the target system
  3. Routing table, process table, kernel statistics, and memory
  4. Registers and processor cache
  5. Physical configuration and network topology
  6. Disk or other storage media
  7. Temporary system files

Identify the correct order of volatility, from most to least volatile, for a typical system.

  • A 4−>3−>7−>6−>2−>5−>1
  • B 2−>1−>4−>3−>6−>5−>7
  • C 4−>3−>7−>1−>2−>5−>6
  • D 7−>5−>4−>3−>2−>6−>1
Explanation

RFC 3227 directs evidence collection from the most volatile data to the least volatile. Its typical-system sequence is registers/cache; routing and process information, kernel statistics, and memory; temporary file systems; disk; relevant remote logging and monitoring data; physical configuration and network topology; and archival media. This corresponds to 4→3→7→6→2→5→1.
