What is Golem immune to?

As a cryptocurrency enthusiast and finance professional, I'm curious to understand the resilience of the Golem network. Specifically, what types of vulnerabilities or threats is the Golem network immune to? Is it secure against traditional hacking attempts? Does it have built-in measures to mitigate the risk of distributed denial-of-service attacks? Additionally, how does it handle the security of user data and transactions? Understanding these aspects is crucial for assessing the overall safety and reliability of the Golem platform.
