It will probably replace the traditional Linux Firewall (netfilter/iptables/nftables) in the coming years, so if you are not using it yet, you should learn now.</span><br style="box-sizing: border-box; caret-color: rgb(35, 35, 51); color: rgb(35, 35, 51); font-size: 14.000000953674316px; white-space: normal;" class=""><br style="box-sizing: border-box; caret-color: rgb(35, 35, 51); color: rgb(35, 35, 51); font-size: 14.000000953674316px; white-space: normal;" class=""><span style="caret-color: rgb(35, 35, 51); color: rgb(35, 35, 51); font-size: 14.000000953674316px; white-space: normal;" class="">eBPF tools and scripts can be used to gain insight into a running processes, such as named. eBPF also provides valuable information for performance tuning on Linux. eBPF sees not only the network packets (like a traditional firewall), but also the syscalls and other kernel information. So it is possible to create richer firewall rules based on application data.</span><br style="box-sizing: border-box; caret-color: rgb(35, 35, 51); color: rgb(35, 35, 51); font-size: 14.000000953674316px; white-space: normal;" class=""><br style="box-sizing: border-box; caret-color: rgb(35, 35, 51); color: rgb(35, 35, 51); font-size: 14.000000953674316px; white-space: normal;" class=""><span style="caret-color: rgb(35, 35, 51); color: rgb(35, 35, 51); font-size: 14.000000953674316px; white-space: normal;" class="">This webinar gives an introduction into the eBPF/BCC toolset and shows how to use the tools to inspect a running BIND 9 process. We will also discuss some security applications for eBPF, such as finding the source of suspicious queries or traffic on the network.</span><br style="box-sizing: border-box; caret-color: rgb(35, 35, 51); color: rgb(35, 35, 51); font-size: 14.000000953674316px; white-space: normal;" class=""><br style="box-sizing: border-box; caret-color: rgb(35, 35, 51); color: rgb(35, 35, 51); font-size: 14.000000953674316px; white-space: normal;" class=""><span style="caret-color: rgb(35, 35, 51); color: rgb(35, 35, 51); font-size: 14.000000953674316px; white-space: normal;" class="">At the end of this webinar there will be an optional Hands-On Session.</span>
