New Article on OTN: Tips for Securing an Oracle Linux Environment

Some time ago, we published Tips for Hardening an Oracle Linux Server on the Oracle Technology Network. This article focused on hardening an Oracle Linux system right after the initial installation, exploring administrative approaches that help to minimize vulnerabilities.

This week we issued a second part,Tips for Securing an Oracle Linux Environment, which focuses on the operational part: detecting intrusion attempts, auditing and keeping systems up-to date and protected.

If you manage Oracle Linux systems in your environment, check out these articles for some invaluable hints and suggestions on how to improve and maintain security of these servers!

New article on OTN: How I Use the Advanced Capabilities of Btrfs

In her first article, "How I Got Started with the Btrfs File System for Oracle Linux", Margaret gave an overview of the Btrfs file system on Oracle Linux and explained the basic file system operations.

In the second part of this article series titled "How I Use the Advanced Capabilities of Btrfs", Margaret now explores some of the more advanced features of this file system like RAID, checksums or filesystem snapshots and clones.

If you want to learn more about this exciting new file system, these two articles provide a solid foundation of information to evaluate and get familiar with Btrfs. Go check them out!

Reminder: OTN Sys Admin Day in Salt Lake City on January 18th

Just a friendly reminder: this year too, we'll continue this series of free one-day events.

OTN Sys Admin Days are like OTN's Developer Days, but we focus on the Sys Admin with two parallel, hands-on Oracle Solaris and Oracle Linux tracks. These are live classroom events and you'll need to bring your own laptop to follow the practical exercises that we will go through in a VirtualBox environment.

The Linux track will cover topics like package management with RPM and yum, storage management with LVM2 and Linux RAID as well as learning the basics of managing the Btrfs file system. The Solaris track will cover the ZFS file system, Solaris containers and security (roles, SMF).

The next OTN Sys Admin Day will take place in Salt Lake City (UT), on January 18th, 8:00am-4:00pm.

Attendance is free, but a registration is required – reserve your spot now by following this link! We look forward to your participation.
