• Post Quantum Cryptography

    Traditional computers are binary digital electronic devices based on transistors. They store information encoded in the form of binary digits each of which could be either 0 or 1. Quantum computers, in contrast, use quantum bits or qubits to store information either as 0, 1 or even both at the same time. Quantum mechanical phenomenons such as entanglement and tunnelling allow these quantum computers to handle a large number of states at the same time. Quantum computers are probabilistic rather...

  • Satellite 5.8 cdn-sync Performance

    Introduction Red Hat Satellite 5.8.0 comes with a new way to synchronize channel-content from Red Hat: cdn-sync. Unlike satellite-sync, which synchronizes content (i.e. channels, packages, errata, and kickstart trees) from RHN Classic servers, cdn-sync retrieves content from Red Hat's CDN servers (the same source which is used by systems registered via subscription-manager). cdn-sync command attempts to keep option parity with satellite-sync where it makes sense to do so. Although Satellite 5.8...

  • Enhancing the security of the OS with cryptography changes in Red Hat Enterprise Linux 7.4

    Today we see more and more attacks on operating systems taking advantage of various technologies, including obsolete cryptographic algorithms and protocols. As such, it is important for an operating system not only to carefully evaluate the new technologies that get introduced, but to also provide a process for phasing out technologies that are no longer relevant. Technologies with no practical use today increase the attack surface of the operating system and more specifically, in the...

    Recently we rolled out a couple new features to help you assess and prioritize your risk. These would be the Likelihood and Impact that you will see assigned to individual Insights Rules. Likelihood is the probability that a system will experience impact described in the rule. Since we are trying to be proactive in detecting the conditions before there is an impact, Likelihood is an important factor when prioritizing work. The higher the Likelihood, the more urgent it is to proactively...

In this part we shall discuss some security and privacy improvements. Remove Obsolete and insecure cryptographic primitives Remove RSA Handshakes When RSA is used for key establishment there is no forward secrecy, which basically means that an adversary can record the encrypted conversation between the client and the server and later if it...
