  • Network Bonding Helper

    We're proud to introduce a new Red Hat Access Labs app: Network Bonding Helper. Red Hat Enterprise Linux allows administrators to bind network interface controllers (NICs) together into a single channel using the bonding kernel module and a special network interface known as a bonding (or channel bonding) interface. Bonding enables two or more network interfaces to act as one, simultaneously increasing the bandwidth and providing redundancy. This app is designed to help you configure bonding....

  • It's all a question of time - AES timing attacks on OpenSSL

    This blog post is co-authored with Andy Polyakov from the OpenSSL core team. Advanced Encryption Standard (AES) is the mostly widely used symmetric block cipher today. Its use is mandatory in several US government and industry applications. Among the commercial standards AES is a part of SSL/TLS, IPSec, 802.11i, SSH and numerous other security products used throughout the world. Ever since the inclusion of AES as a federal standard via FIPS PUB 197 and even before that when it was known as...

  • OpenSSL Privilege Separation Analysis

    As part of the security response process, Red Hat Product Security looks at the information that we obtain in order to align future endeavors, such as source code auditing, to where problems occur in order to attempt to prevent repeats of previous issues. Private key isolation When Heartbleed was first announced, a patch was proposed to store private keys in isolated memory, surrounded by an unreadable page. The idea was that the process would crash due to a segmentation violation before the...

  • LVM RAID Calculator

    We're proud to introduce a new Red Hat Access Labs app: LVM RAID Calculator. To create Logical Volume Manager (LVM) on RAID, you usually need to execute several commands and carefully provide parameters for each. A subtle error in a command parameter might cause the execution to fail or affect the performance of your LVM. This app is designed to walk you though creating LVM on RAID by dividing the creation procedure into a few steps and generating all necessary commands with appropriate...

  • OpenSSL MITM CCS injection attack (CVE-2014-0224)

    In the last few years, several serious security issues have been discovered in various cryptographic libraries. Though very few of them were actually exploited in the wild before details were made public and patches were shipped, important issues like Heartbleed have led developers, researchers, and users to take code sanity of these products seriously. Among the recent issues fixed by the OpenSSL project in version 1.0.1h, the main one that will have everyone talking is the "Man-in-the-middle...

    We're excited to announce the new ability to comment on new documentation within the Customer Portal. This is live and available today and we'll begin to roll this out for future documentation releases as well. For an example see the Red Hat Enterprise Linux 7 Release Notes. Several months ago we introduced a survey for our documentation to gather feedback from the people who use it the most. With this most recent release we wanted to take that a step further, as we felt it was really...

  • Log Analyzer

    We are proud to introduce a new Red Hat Access Labs app: Log Analyzer Log Analyzer is a multi-purpose log parsing web application with an emphasis on break/fix and identification of errors in your log files. Currently there are plenty of enterprise solutions in the log parsing arena but none that work in an on-demand fashion and none that tie into Red Hat's ecosystem. This app fills that void and provides a means to parse your logs (see the info page for currently supported log types) into a...

  • Defeating memory comparison timing oracles

    The standard C functions for comparing two strings of the same length, memcmp can be implemented naïvely as follows: For each byte in the two strings: From both strings, load the byte at the position currently under consideration and compare their values. If they are not equal, return some value matching the sign of their difference (as unsigned bytes). If no differing bytes are discovered, return 0. From time to time, there are reports that this implementation results in a timing oracle...

  • File System Layout Calculator

    We're proud to introduce a new Red Hat Access Labs app: File System Layout Calculator. To create file systems on multi-disk RAID arrays, you need to use the mkfs command with proper arguments. You need to carefully calculate the value for arguments like stride and stripe-width to make sure that your file systems align with the underlying RAID arrays and that you have maximized performance. This app is designed to save you the trouble of making tedious and error-prone calculations by creating...

  • SSL/TLS Everywhere – visions of a secure OpenStack

    As most people familiar with OpenStack are already aware, it is made up of many software components that are typically deployed in a distributed manner. The more scalable an OpenStack deployment is, the more distributed the underlying components are as the infrastructure is usually scaled out horizontally on commodity hardware. As a consequence of this distributed architecture, there are many communication channels used between all of the software components. We have users communicating...

  • New SELinux Feature: File Name Transitions

    In Red Hat Enterprise Linux 7, we have fixed one of the biggest issues with SELinux where initial creation of content by users and administrators can sometimes get the wrong label. The new feature makes labeling files easier for users and administrators. The goal is to prevent the accidental mislabeling of file objects. Accidental Mislabeling Users and administrators often create files or directories that do not have the same label as the parent directory, and then they forget to fix the label...

  • New Red Hat Enterprise Linux 7 Security Feature: systemd-journald

    A lot has already been written about systemd-journald. For example, this article describes the security benefits of the journal. I would argue that systemd-journal is not a full replacement for syslog. The syslog format is ubiquitous, and I don't see it going away. On all Red Hat Enterprise Linux 7 machines, syslog will still be on by default. This is because it's still the defacto mechanism for centralizing your logging data, and most tools that analyze log data read syslog data. The journald...

  • New Red Hat Enterprise Linux 7 Security Feature: PrivateTmp

    One of the reasons I am really excited about Red Hat Enterprise Linux 7 is the amount of new security features we have added, and not all of them involve SELinux. Today, I want to talk about PrivateTmp. One of my goals over the years has been to stop system services from using /tmp. I blogged about this back in 2007. Anytime I have discovered a daemon using /tmp, I have tried to convince the packager to move the temporary content and FIFO files to the /run directory. If the content was...

  • New Red Hat Enterprise Linux 7 Security Feature: systemd Starting Daemons

    Why is this a security feature? In previous releases of Red Hat Enterprise Linux, system daemons would be started in one of two ways: At boot, init (sysV) launches an initrc script and then this script launches the daemon. An admin can log in and launch the init script by hand, causing the daemon to run. Let me show you what this means from an SELinux point of view. NOTE: In the code below, @ means execute, --> indicates transition, and === indicates a client/server communication. The...

    We're proud to introduce a new Red Hat Access Labs app: KDump Helper. KDump is a reliable kernel crash-dumping mechanism that captures crash dumps for troubleshooting issues like kernel crashes, hangs, and reboots. Setting up KDump usually requires a series of steps and configurations. We developed the KDump Helper app to simplify the process and reduce the effort required to set KDump up on your machines. Input a minimum amount of information and this app will generate an all-in-one script for...
