Adaptive SQL Plan Management (SPM) in Oracle Database 12c Release 1 (12.1)

SQL Plan Management was introduced in Oracle 11g to provide a "conservative plan selection strategy" for the optimizer. The basic concepts have not changed in Oracle 12c, but there have been some changes to the process of evolving SQL plan baselines. As with previous releases, auto-capture of SQL plan baselines is disabled by default, but evolution of existing baselines is now automated. In addition, manual evolution of sql plan baselines has been altered to a task-based approach. This article focuses on the changes in 12c.

iPhone’s Passcode Bypassed Using Software-Based Bruteforce Tool

Last week, a blogger reported on a $300 device called the IP Box, which was allowing repair shops and hackers to bypass passcodes and gain access to locked iOS devices. But it turns out that expensive hardware isn’t required; TransLock, a new utility for Mac, can do the same job over USB.

MDSec’s video proved that the IP Box was able to bypass an iOS passcode using brute-force and maintain the data on an iPhone, iPad, or iPod touch even when the device is set to erase itself automatically when an incorrect passcode has been entered ten times.

Google adds ‘On-body detection’ Smart Lock mode to Android Lollipop devices

Google seems to be rolling out a new ‘Smart Lock’ feature for Android devices running Lollipop — On-body detection. This new feature will only lock your device when it is sitting on a table or in your pocket.

The feature will make use of the accelerometer on your Android device to detect any movement. In case it does not detect any movement, it will automatically lock your device. But if you are holding the device in your hand and it is already unlocked, On-body will keep it unlocked.

In case you hand over your device to someone while it is unlocked, On-body will keep it unlocked. The feature cannot determine who is holding the device, it only knows that someone is holding it and thus keeps it unlocked.

Google is rolling out the feature only to selected users for now, but it is likely that a wider rollout will start within the next few weeks. For now, the feature has only shown up on Nexus devices, but it is likely that Google will roll it out to other Android devices running Lollipop as well.


BlackBerry launches encrypted enterprise messaging service BBM Protected for iOS

BlackBerry today announced that it is bringing BBM Protected — its enterprise-grade encrypted messaging service — to BBM for iOS.

The keys to encrypt messages in BBM Protected will be generated on the iPhone device itself. This prevents any “‘man in the middle’ hacker attacks, providing greater security than competing encryption schemes, and earning BBM Protected FIPS 140-2 validation by the U.S. Department of Defense.”

The feature can be easily deployed in enterprises that already use BBM for communication, and does not require any additional setup or OS upgrade on their side.

BBM Protected users can start a chat with other BBM Protected users in their organisation as well as outside of it. In case the recipient (or sender) does not use BBM Protected, the other party in the conversation can still initiate an encrypted and trusted chat environment.

BBM Protected is a paid service, though BlackBerry is offering a free 30-day trial to enterprises. It is also available for Android and BlackBerry OS 10 running devices.
