Small business owners rarely find themselves with nothing to do. Instead, they prioritize productive tasks and constantly address urgent issues. As a result, incident response planning and backup testing can easily be neglected unless they are intentionally scheduled and assigned.
When should a small business practice Incident Response?
A small business should regularly practice incident response to ensure its team is well-prepared to effectively handle and mitigate security incidents when they occur. However, determining the most appropriate interval or trigger for these practices can be confusing. It is essential to establish a consistent schedule and clear criteria for triggering these drills to maintain readiness and improve response strategies.
Here are some scenarios and considerations for practicing incident response:
Regular Schedule
Schedule incident response drills or exercises on a regular basis. This could be quarterly, semi-annually, or annually, depending on the size and complexity of the business. It can be beneficial to align these drills with other regularly scheduled tasks to ensure they are consistently carried out.
New Staff Onboarding
Include incident response training as part of the onboarding process for new employees to familiarize them with the organization’s procedures and protocols. This ensures all team members are prepared to respond effectively from the start.

Incident response scenarios for small businesses should be realistic and tailored to the organization’s industry and potential threat landscape. For example, if you are a small business machine shop, you may not have many production-critical remote workers, but there could be business-critical roles that can be managed off-site. Tailoring scenarios to reflect these realities ensures that incident response plans are practical and effective.
What are some realistic scenarios for a small business to use when practicing Incident Response?
Here are some incident response scenarios tailored for small businesses. Some of these scenarios can be practiced independently, while others may require the involvement of a third party or a contracted managed service provider:
