Which Part of the BIA? — TechKnowSurge

About this interactive

A contingency plan takes a lot of time and money, so a business impact analysis (BIA) decides where to spend it. The lesson builds one in steps. - Impact categories are the kinds of harm the business measures: lost revenue, lost assets, fines, the cost of notifying people, lost competitive advantage, damage to reputation. - Impact levels put a size on each category, set by how much risk the company will take on. In the lesson, a revenue loss under $75,000 is minimal, $75,000 to $1 million is moderate and over $1 million is severe. - Essential functions are the mission-critical processes: invoicing customers, paying vendors, shipping products. - Maximum tolerable downtime (MTD) is how long one of those functions can be out before the harm is more than the business accepts. In the lesson, invoicing can be down no more than 24 hours. - Resource requirements are the systems each function needs. Getting paid needs the invoicing system, the web server and the payment processing system. Each resource then gets its own recovery time objective, and the recovery priorities follow. A quick test for a card: is it a kind of harm, a size of harm, a business process, a time limit on a process, or the systems behind a process? Security+ lists the business impact analysis under risk management, with RTO, RPO, MTTR and MTBF.
