Which of the following is NOT a challenge in handling cloud security incident logs?

The correct choice highlights that timestamp synchronization is not considered a significant challenge in handling cloud security incident logs. In cloud environments, most cloud service providers have robust mechanisms for logging and maintaining consistent timestamps across their services. These systems often utilize synchronized time protocols, which help ensure that log entries across different services and locations have consistent timestamps. This synchronization is crucial for accurately correlating log events when conducting incident investigations.

On the other hand, decentralization of logs, evaporation of logs, and having multiple layers and tiers present more considerable hurdles. Decentralization can complicate the aggregation and analysis of logs since logs may be stored in various locations, making it challenging to get a comprehensive view of security incidents. Evaporation of logs refers to the potential loss or expiration of log entries over time, which can hinder the ability to investigate incidents effectively. Multiple layers and tiers in a cloud environment can create complexity in understanding the flow of data and events across the entire system, which makes monitoring and analyzing logs more difficult.
