Application allowlisting is the practice of specifying an index of approved applications or executable files that are permitted to run on a system by a specific user

"This is often used on a multi-user system or some kind of a shared hosting server, where multiple users exist and they have to be given limited permissions, so that they can only run approved applications on the shared system.

Note: A lot of external documentation uses the term "whitelist" in the place of allowlist and "blacklist" in the place of denylist. Red Hat is trying to be more inclusive by eradicating problematic language.

Red Hat Enterprise Linux (RHEL) and many other distributions have SELinux available, which can be used to effectively block applications which are not explicitly allow listed, and commercial products are also available. However technologies like SELinux are designed to control application behaviour but do not know which applications are trusted. Therefore SELinux is complementary to other technologies because they handle different aspects of system security..."


People working in the telco space with DPDK accelerated Open vSwitch have probably seen questions about packet drops a number of times and with multiple customers

"Is it OVS-DPDK, or is it the VNF? Why is it happening, and where? What happened, and more importantly, what can we do about it? In this post we'll look at troubleshooting and answering some of these questions.

About three years ago, at OVScon 2017, Ericsson came up with a proposal made of two parts:

  • Exposing more advanced metrics from the PMD Threads

  • Improve how drop packets are classified in Open vSwitch

Since then (and many OVS-DPDK escalations after) the upstream community (including a number of Red Hatters) has worked really hard. So it was clear, we had to improve the usability and the observability features of OVS-DPDK..."
