Red Hat Enterprise Linux 8 Beta has been supporting OpenSSL 1.1.1 and TLS 1.3. Red Hat is enabling server applications on the platform to use the latest standards for cryptographic protection of customer data.

RHEL8 supports more efficient Linux networking in containers through IPVLAN. It also includes a new TCP/IP stack with Bandwidth and Round-trip propagation time (BBR) congestion control, which enables higher performance & minimized latency. We can convert existing iptables or ip6tables rules into nftables. nftables support advantages like it offer a single framework for packet filtering.
