Options

• AConfigure more robust word lists for blocking suspicious emails
• BConfigure appropriate regular expression rules per suspicious email received
• CConfigure Bayesian filtering to block suspicious inbound email
• DConfigure the mail gateway to strip any attachments

• B
  77% (20)
• C
  12% (3)
• D
  8% (2)

Explanation

Given that keyword word-list matching is already in place, configuring regular expression (regex) rules provides more precise and flexible pattern matching tailored to the specific characteristics of suspicious emails as they are received. Regex allows administrators to craft granular patterns that go beyond static word lists, targeting structural patterns in phishing emails (e.g., spoofed sender formats, obfuscated URLs). Option C (Bayesian filtering) is a valid and often more effective long-term approach as it learns statistically from spam patterns; however, the question implies a targeted, reactive improvement to existing controls, which regex best provides. Option D (stripping attachments) is too broad and would disrupt legitimate business email.
