In this case, all process operations continue to flow seamlessly, but you could miss specific file and socket-related events that eBPF would otherwise capture. For more information, see Use eBPF-based sensor for
Cloud computing has, in a way, transformed IT infrastructures, thus rendering operating systems dependent on physical machines. They now act as a sort of portal between local hardware and cloud environments to ensure that cloud-based applications, remote data storage, and virtualization are smoothly ...
Are there tagging abilities, to help sort images? Can you tag images as approved only for development, and then testing, and then production environments? Does the registry offer visible metadata that allows you to track known vulnerabilities? Can you use the registry to assign and automate polic...

Prometheus stores data locally in a custom database. Distributed systems are challenging to make reliable, so Prometheus does not attempt to do any form of clustering. In addition to reliability, this makes Prometheus easier to run. Over the years, storage has gone through a number of redesigns...
Theeventsis yet another time a mask which defines in what sort of events are we interested. epoll_wait intepoll_wait(intepfd,structepoll_event*events,intmaxevents,inttimeout); Here, again we have to pass the file descriptor of the epoll instance. The second argument is an array of instanc...
Log files capture things like unsuccessful log-in attempts, failed user authentication, or unexpected server overloads, which can signal to an analyst that a cyberattack might be in progress. The best security monitoring tools can send alerts and automate responses when these events are detected ...
Notice how the EF.Property method can be used to access values from the period columns. This is used in the OrderBy clause to sort the data, and then in a projection to include these values in the returned data.This query brings back the following data:...
