Security Hub collects security data from AWS services, organizes it, applies standards, and helps users monitor and respond to security issues.

Execution Sample

AWS

1. Enable Security Hub
2. Security Hub collects findings
3. Findings are normalized
4. Standards are applied
5. Insights and alerts generated
6. User reviews findings

This sequence shows how Security Hub processes security data step-by-step.

Process Table

Step	Action	Input	Output	Notes
1	Enable Security Hub	AWS Account	Security Hub activated	Start monitoring security findings
2	Collect Findings	Findings from AWS services (GuardDuty, Inspector, etc.)	Raw security findings	Gather data from multiple sources
3	Normalize Findings	Raw findings	Standardized findings	Convert to common format
4	Apply Standards	Standardized findings	Findings with compliance status	Check against CIS, PCI DSS, etc.
5	Generate Insights	Findings with compliance status	Security insights and alerts	Highlight important issues
6	User Review	Security insights and alerts	User actions (investigate, remediate)	User decides next steps
7	Continuous Monitoring	Ongoing findings	Updated insights	Repeat process for ongoing security

💡 Process continues indefinitely for continuous security monitoring

Status Tracker

Variable	Start	After Step 2	After Step 3	After Step 4	After Step 5	After Step 6	Final
Security Hub State	Disabled	Enabled	Enabled	Enabled	Enabled	Enabled	Enabled
Findings	None	Raw findings collected	Normalized findings	Findings with compliance status	Insights and alerts generated	User reviewed findings	Continuous updates
User Actions	None	None	None	None	None	Investigate or remediate	Ongoing

Key Moments - 3 Insights

Why does Security Hub normalize findings from different AWS services?

Normalization converts diverse findings into a common format, making it easier to apply standards and generate insights, as shown in step 3 of the execution_table.

What happens after Security Hub applies security standards to findings?

It marks findings with compliance status and generates insights and alerts to highlight important issues, as seen in steps 4 and 5 of the execution_table.

Does Security Hub stop monitoring after the user reviews findings?

No, Security Hub continuously monitors and updates insights with new findings, shown in step 7 of the execution_table.

Full Transcript

AWS Security Hub is a service that helps you see and manage security alerts from many AWS services in one place. First, you enable Security Hub in your AWS account. Then, it collects security findings from services like GuardDuty and Inspector. These findings are converted into a standard format so they can be compared and analyzed easily. Security Hub checks these findings against security standards such as CIS and PCI DSS. It then creates insights and alerts to highlight important security issues. Users can review these alerts and decide what actions to take, like investigating or fixing problems. Security Hub keeps monitoring continuously to keep your security status updated.
