Impossible travel refers to the analysis and monitoring of user access patterns to identify improbable geographical connections. This security measure helps detect suspicious activities that may indicate fraudulent login attempts, security breaches, or other malicious behavior targeting public sector platforms.

How does it work

Impossible travel detection works by monitoring user access patterns and comparing the geographical locations of their connections. If the system detects a login from a location that would be implausible to reach within a certain timeframe considering the user's previous login, the connection is flagged as suspicious. This can help cybersecurity professionals and IT administrators identify possible fraud, data breaches, and other security threats.

Pros & Cons

• Pros:

  
  
  1. Proactive detection of suspicious activities: Impossible travel detection allows public sector IT professionals to preemptively identify potential security breaches, reducing their potential impact.

  2. Potential false alarms: Impossible travel detection may yield some false positives, flagging connections as suspicious when they are actually legitimate. This can lead to unnecessary investigations and resource allocation, as well as user frustration.

Tactical implementation

Implementing an impossible travel detection system requires several key steps:

1. Create an automated log analysis system for user access patterns: Develop or integrate a system that can analyze user access logs to identify patterns such as login frequency, connected devices, and geographical locations. This system should be capable of detecting improbable travel-based connections by comparing the timeframes and locations of user logins.

   
   

2. Set thresholds for triggering geographical-based alerts: To minimize false alarms, establish reasonable thresholds for impossible travel alerts. For example, consider factors such as the average distances between user logins and the time it would take to travel between locations. Adjust these thresholds over time as necessary to maintain a delicate balance between security and usability.

   
   

3. Implement verification procedures for flagged instances: When an impossible travel alert is triggered, set up a process to verify the flagged login attempt. This may include contacting the user directly, requiring them to complete extra authentication steps, or temporarily suspending access until the situation is resolved. Establish clear protocols for verification to ensure a swift and effective response to potential security threats.

   
   

By incorporating an impossible travel detection strategy into your public sector organization's cybersecurity measures, you can help proactively identify and prevent potential security breaches, protect sensitive government data, and maintain the integrity of your digital services and applications.
