Which network architecture is often used with blockchain ledgers to mitigate risks associated with a centralized authority but is not commonly used in UEBA?

The choice of P2P (Peer-to-Peer) network architecture is particularly relevant in the context of blockchain ledgers because it allows for decentralized data management and transaction validation. In a P2P network, each participant (or node) has equal authority and responsibility, which significantly reduces the risks associated with relying on a single, centralized authority. This decentralization is a key feature of blockchain technology, as it enhances security, transparency, and trust among users.

In contrast, UEBA (User and Entity Behavior Analytics) typically relies on centralized data analysis and processing to identify anomalous behavior based on established baselines. The use of a P2P model does not align with how UEBA systems operate since they need centralized log and event data to effectively monitor and analyze user behaviors for security purposes. Therefore, while P2P is central to the functioning of blockchain, it does not fit well within the framework of UEBA, which is designed to function with centralized data sources for effective analysis and threat detection.
