Unused EC2 Key Pairs Stat Card

Overview

The "Unused EC2 Key Pairs Stat Card" provides insights into EC2 key pairs that are no longer in use within your AWS environment. EC2 key pairs are essential for securely accessing instances via SSH. Over time, unused key pairs may accumulate, and it’s crucial to track and manage them to reduce the attack surface and maintain security best practices. This stat card helps IT and Security teams identify and clean up unused key pairs to minimize potential vulnerabilities.

Why It Matters

For IT Engineers:

1. Security Hygiene:

   • Unused EC2 key pairs can be a potential security risk if they are not properly managed. By monitoring this stat card, IT engineers can ensure that key pairs that are no longer in use are removed, reducing the risk of stale or orphaned credentials being exploited.

2. Resource Optimization:

   • Key pairs that are not in use still count as resources within the AWS environment. Identifying and deleting unused key pairs helps optimize the environment, ensuring that only the necessary resources are maintained.

3. Access Control and Compliance:

   • Ensuring that only active, necessary key pairs are retained helps enforce strong access control policies and contributes to meeting security and compliance standards by reducing the risk of unauthorized access.

For Security Engineers:

1. Minimizing Attack Surface:

   • Unused key pairs can still be used if compromised. By regularly reviewing the stat card and removing unused key pairs, security engineers can minimize the number of entry points into the system, making it more difficult for attackers to gain unauthorized access.

2. Audit and Compliance:

   • Many security frameworks require periodic audits of key management practices, including removing unused or expired keys. The stat card helps security teams ensure that key pairs are only used when necessary and are retired in a timely manner to maintain compliance with security policies.

3. Incident Prevention:

   • Leftover key pairs, especially those that are no longer needed, pose an unnecessary risk. Monitoring this stat card helps security engineers prevent incidents by ensuring that all EC2 key pairs are relevant, active, and securely managed.

By leveraging the "Unused EC2 Key Pairs Stat Card," IT and Security teams can improve their security posture, ensuring that key pairs are actively managed, reducing risks related to unauthorized access and simplifying key management across the AWS environment.
