Strategy 3: Impossible Travel Analysis
What is impossible travel analysis
Impossible travel analysis is a technique used by cybersecurity experts to detect and flag suspicious access attempts of sensitive accounts and protected systems, such as APIs. This method is particularly useful in the telecom and utility sectors, where efficient and secure APIs are crucial for safeguarding valuable customer data and protecting business operations.
How it works:
Impossible travel analysis examines API requests by looking at the timestamps and IP geolocation data associated with each request. By comparing the physical locations of consecutive requests and the time interval between them, the system can identify access attempts that seem unlikely or "impossible" due to the short amount of time and geographic distance between the requests. Such suspicious activities can indicate unauthorized access attempts, data breaches, or other fraudulent actions related to API abuse.
An example of an impossible travel scenario would be a user logging in from Paris, and then, within a few minutes, attempting to access an API from a location in Tokyo. This suspicious activity suggests that the user's account may have been compromised or a malicious third party is attempting unauthorized access, requiring immediate attention.
Pros & Cons:
- Prevents unauthorized access attempts and reduces the likelihood of successful cyberattacks.
- Identifies potential fraud attempts before they can cause significant damage to systems and data.
