  • What’s Your Total Risk?

    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...

  • Is Your Bond Strong?

    Most critical physical systems use multiple network interfaces bonded together to provide redundancy and, depending on the workload, to provide greater network throughput. Bonding can be configured in either manner depending on the mode specified in the bonding configuration file. It is quite common to misconfigure bonding. It is case sensitive so something might be capitalized that shouldn’t be. You might have misunderstood the documentation and configured an incorrect or suboptimal bonding...

  • Do you know where that open source came from?

    Last year, while speaking at RSA, a reporter asked me about container provenance. This wasn’t the easiest question to answer because there is a lot of nuance around containers and what’s inside them. In response, I asked him if he would eat a sandwich he found on the ground. The look of disgust I got was priceless, but it opened up a great conversation. Think about it this way: If there was a ham sandwich on the ground that looked mostly OK, would you eat it? You can clearly see it’s a ham...

    Cryptographic protocols and algorithms have a limited lifetime—much like everything else in technology. Algorithms that provide cryptographic hashes and encryption as well as cryptographic protocols have a lifetime after which they are considered either too risky to use or plain insecure. In this post, we will describe the changes planned for the 6.9 release of Red Hat Enterprise Linux 6, which is already on Production Phase 2.

  • A leap second is coming

    The basic timekeeping standard for almost all of the world's local time zones is called Coordinated Universal Time (UTC). UTC is derived from International Atomic Time (TAI) and Universal Time (UT1), also known as mean solar time because it’s the time it takes for the Earth to rotate once on its axis. Because the rotation of the earth varies a bit over time and is slowly decreasing its mean rotation speed, a deviation occurs between UTC and UT1. When this deviation approached .9 seconds, a leap...

  • Evolution of the SSL and TLS protocols

    The Transport Layer Security (TLS) protocol is undoubtedly the most widely used protocol on the Internet today. If you have ever done an online banking transaction, visited a social networking website, or checked your email, you have most likely used TLS. Apart from wrapping the plain text HTTP protocol with cryptographic goodness, other lower level protocols like SMTP and FTP can also use TLS to ensure that all the data between client and server is inaccessible to attackers in between. This...

  • Don’t panic! Don’t let your kernel do it either.

    A system crash can be one of the most frustrating issues that administrators can encounter in their day to day work. They often strike without warning, require hard reboots, and can kill a process uncleanly, leaving various locked files in place that an admin must go back and manually clean up. These kind of interruptions can take a few minutes to a few hours to overcome. That’s time you could be spending engineering new solutions that change the world, or at the very least, drinking some...
