| Financial Records | 750,000 | 10 | 75,000 |
| Business Continuity | 1,000,000 | 5 | 50,000 |
This number game helps to pinpoint where to toss cash and effort, based on how much it might hurt the wallet or the boss.
Qualitative and Semi-Quantitative Assessments
Let’s shift gears to gut-feeling risk assessments, which are more of a guessing game. You’ve got teams making up scenarios, chatting up the staff, and pulling together a picture of what could mess up their flow (Drata). It’s kind of like piecing together a jigsaw.
Then there’s the hybrid way, which plops some numbers on those gut feels. Imagine ranking risks on a scale from 1-10. It’s like saying, “Hey, this risk feels like a 5 on my risky-meter.”
Example Table: Semi-Quantitative Risk Assessment
| Risk | Impact (1-10) | Likelihood (1-10) | Risk Score (Impact x Likelihood) |
|---|---|---|---|
| Data Breach | 8 | 6 | 48 |
| System Downtime | 7 | 5 | 35 |
| Regulatory Non-compliance | 9 | 4 | 36 |
This mixed method sets some steady ground for deciding what’s urgent and what can wait till after lunch.
Vulnerability-Based Risk Assessment
This one’s the treasure hunt for weak spots. It’s all about poking around the IT setup to find where you might trip over a wire (Drata). Seeing what glitches and gaps could let the bad guys sneak in gives a real heads-up on what needs a sturdy lock.
The checklist includes spotting weaknesses, categorizing them, and figuring out which ones are jumping up and down for attention. Fixing the worst issues first keeps the tech house standing tall and secure.
Example Table: Vulnerability-Based Risk Assessment
| Vulnerability | Exploitability (1-10) | Impact (1-10) | Risk Priority |
|---|---|---|---|
| Unpatched Software | 9 | 8 | High |
| Inadequate Access Controls | 7 | 6 | Medium |
| Weak Password Policies | 5 | 5 | Low |
