Heatmap Analysis
Heatmap Analysis
Heatmap Analysis is a technique used to visualize data, making it easier to identify trends and patterns. What is a Heatmap?
A heatmap is a graphical representation of data where values are depicted by color.
It uses a warm-to-cool color spectrum to show activity levels, with red indicating high activity and green indicating low activity.
Why Use Heatmaps in Cyber Threat Intelligence?
Heatmaps help make complex data sets comprehensible and actionable.
They allow you to quickly see trends and understand what actions to take next.
In cyber threat intelligence, heatmaps can show intrusion attempts and help identify knowledge gaps about adversaries.
Creating a Heatmap in Excel
Prepare Your Data: Create an Excel spreadsheet with rows representing activities per month and columns representing different campaigns.
Select Data: Highlight the numerical data you want to visualize.
Apply Conditional Formatting:
Go to the Home menu.
Choose Conditional Formatting.
Select a color scale (e.g., red to green) where red indicates the highest activity level.
Analyze Results: Look at the heatmap to identify high activity periods (red areas) and low activity periods (green areas).
Benefits of Heatmap Analysis
Identify Trends: Quickly see periods of high and low activity.
Understand Adversaries: Determine patterns in intrusion attempts, such as increased activity during certain months.
Prioritize Actions: Use the insights to decide on the best course of action to address threats.
