What is the update interval configured for Snort rules?

• A. 1 Day
• B. 12 Hours
• C. 1 Hour
• D. 7 Days

Answer: (A)

Rule updates for Snort are about how often the system pulls in new rule signatures. The update interval sets the schedule for refreshing the rule set from your rule source. A daily interval fetches the latest rules once every 24 hours, which is a solid balance: you stay reasonably current with new threats while keeping network traffic and processing overhead manageable. More frequent pulls (every 12 hours or every hour) increase overhead and may yield diminishing returns for many environments. Less frequent updates (every 7 days) leave you vulnerable to newer signatures for longer. So the configured update interval is daily.
