the International Olympic Association (IOA) and the International Olympic Committee (IOC), it becomes clear that the IOC plays the central role in overseeing and organizing the Olympic Games and promoting the Olympic Movement globally.

2. IOA or Indicator of Attack, is a pattern of behavior
that indicates that a cyber attack is in progress or
is about to happen. IOAs are based on the
knowledge of how attackers typically operate,
and they can be used to detect a wide range of
attacks.
EXAMPLE
• A sudden increase in the number of failed login
attempts to a system.

3. IOC or Indicator of Compromise, is a piece of
evidence that indicates that a system has been
compromised. IOCs can be anything from a
specific IP address to a file hash to a registry
entry. IOCs are often used to detect known
threats, such as specific malware strains or
attack vectors.
EXAMPLE
• The presence of a specific malware file on a
system.

4. 1. Define Objectives
• IOA: Identify the objectives for detecting mali
cious activities before they compromise the
system.
• IOC: Define the goals for identifying signs of
a successful breach or compromise.
2. Gather Data
• IOA: Collect data on attack tactics,
techniques, and procedures (TTPs).
• IOC: Gather logs, network traffic data, and
system events.

5. 3. Analyze Threat Intelligence
• IOA: Analyze threat intelligence feeds,
reports, and forums for emerging threats and
attack patterns.
• IOC: Review threat intelligence for known
signatures, malware hashes, malicious IPs,
and domains.
4. Develop Indicators
• IOA: Develop indicators based on observed
attack behaviors, anomalies, and patterns.
• IOC: Create indicators using known
compromised elements such as file hashes,
IP addresses, URLs, and email addresses.

6. 5. Implement Detection
• IOA: Implement detection rules and alerts in
security tools such as SIEM, IDS, and EDR.
• IOC: Integrate IOC signatures into security
appliances, firewalls, and endpoint protection
platforms.
6. Test and Validate
• IOA & IOC: Test the indicators against
historical data and simulated attack
scenarios to validate their effectiveness.
7. Refine and Update:
• IOA & IOC: Continuously refine and update
indicators based on evolving threats and
false positive/negative feedback.

7. 8. Automate and Integrate:
• IOA & IOC: Automate the process of gathering
and analyzing threat intelligence. Integrate
IOA and IOC with incident response and threat
hunting workflows.
9. Share and Collaborate:
• IOA & IOC: Share indicators with trusted
partners, ISACs (Information Sharing and
Analysis Centers), and threat intelligence
communities.
10. Educate and Train:
• IOA & IOC: Educate and train security teams
on the latest threats and indicators. Conduct
regular drills and exercises to enhance
detection and response capabilities.
