Choosing the Right Encryption Approach for RDBMS

Sometimes, specially now a days when people are planning to move to cloud, security is one of the key factor, and in my experience, what I saw is the cloud architect tries to sell the full disk encryption as a solution for all applications, databases etc. Which in my opinion, is absolutely incorrect.

The goal of this post is to evaluate, at a higher level, different encryption approach for different scenario (specially RDBMS) to better inform the decision making process.

ZERO Downtime Kernel Security updates for Oracle & Redhat Linux

Linux Kernel vulnerabilities, e.g. Kernel Side-Channel Attacks (Meltdown, Spectre), Dirty COW, Linux Kernel Double Fetch Denial of Service Vulnerability, udp.c in the Linux kernel ... … … the list goes on and on.

Linux kernel security updates with important new security and reliability patches are released about once per month to stay up to date with important kernel and user-space security updates.

Industry regulations and best practices require companies to apply these security updates and patches regularly because security is compromised by a failure to update. System administrators are forced to choose between known best practices and system reboots that are costly and disruptive.

Since these are kernel security fixes which means the operating system requires restart in order to active the new kernel and the fixes.

ONLY to fix Linux kernel vulnerabilities, every month organizations have hundreds of hour's system downtime in every quarter at minimum.

Next Oracle Release will be Oracle Database 18 instead

Release 12.2: New releases will be annual and the version will be the last two digits of the release year. The release originally planned as will now be release 18, and the release originally planned as will be release 19. Releases 18 and 19 will be treated as under the umbrella of 12.2 for Lifetime Support purposes. The current plan is for Oracle Database 19 to be the last release for 12.2. This may change in the future to Oracle 20 as the last release for 12.2.
