MySQL to fortify defenses with Citadel

Hop, skip and an upgrade


MySQL User Conference MySQL is targeting improved security and privacy with a version of its database codenamed Citadel due in 2009 that’ll also see MySQL speed up product release cycles.

Citadel will try to close the gap on IBM and Oracle with security and privacy capabilities in the areas of group-level access privileges and transparent data encryption at the table and column level.

Management permissions are currently set at an individual level with data encryption set using functions. Also due in Citadel is auditing and external authentication.

The changes are designed to help bring existing, web-centric MySQL customers inline with governments' regulatory and privacy rules, while also bringing MySQL to big, established businesses users tasked with meeting security and compliance demands.

MySQL hopes to bypass established rivals by adopting new techniques, particularly in encryption.

Zack Urlocker, vice president of products for Sun's database group, told Reg Dev: "There are standards we have to respect with privacy rules and encryption. MySQL has gone from a nice, speedy database to: 'I'm betting my database on MySQL'.

"Web sites are becoming more enterprisey and the enterprises are becoming more scale and web oriented."

Citadel will mark the latest phase in growth for a database that made its name on the web and by being embedded with ISV applications. Already The Sun-Microsystems-owned MySQL plans updates this year to boost its credentials in the fields of performance and scale.

To get there, MySQL plans to make greater use of parallel release schedules for the different projects that comprise the database, enabling more frequent releases - every 12 months - and simplified adoption.

Urlocker said parallel release cycles would mean fewer jumps for users upgrading.

The roadmap currently includes MySQL version 5.1 this June with version 6.0 hitting soon after, in the fourth quarter. Version 6.x has no due date but alpha testing is scheduled for "late" 2008, with Citadel following in the middle of next. By the time version 5.1 ships, it'll be more than two and a half years since the last big release, version 5.0, shipped.

MySQL 6.0 will include the highly anticipated Falcon transactional storage engine. Despite apparently out performing and "leap frogging" InnoDB on scale out, and despite the fact Falcon runs most InnoDB engines, MySQL was at pains to stress Falcon is no InnoDB replacement - InnoDB was purchased by Oracle in 2005 forcing MySQL to seek alternatives as Oracle's plans were unclear. Falcon, it seems, is being aimed at large, parallel, multi-core systems. Automated back up, meanwhile, is another key feature planned for MySQL 6.0 to remove the need for file dumps.

Also due in the fourth quarter of this year with MySQL 6.0 and Falcon is a new load balancer and connection manager. It's hoped, meanwhile, the Maria storage engine will make it in time for the version 6.0 release. Ahead of the fourth quarter, MySQL this year plans updates to MySQL clustering, the LDAP interface and data warehousing.

MySQL version 6.x will see updates to management and performance tuning. Planned changes include foreign keys for the database's many storage engines, improvements to prepared statements and replication with the addition of check sums, improvements in optimizers with faster check-sum queries, enhanced online back-up catalogues and changes to stored procedures with signal/resignal.

For database developers and DBAs, meanwhile, MySQL has opened early talks with the NetBeans and Eclipse communities over open source tools for MySQL.®

    In brief Prisons around the US are installing AI speech-to-text models to automatically transcribe conversations with inmates during their phone calls.

    A series of contracts and emails from eight different states revealed how Verus, an AI application developed by LEO Technologies and based on a speech-to-text system offered by Amazon, was used to eavesdrop on prisoners’ phone calls.

    In a sales pitch, LEO’s CEO James Sexton told officials working for a jail in Cook County, Illinois, that one of its customers in Calhoun County, Alabama, uses the software to protect prisons from getting sued, according to an investigation by the Thomson Reuters Foundation.

    Another terrible launch, but DICE is already working on improvements

    The RPG Greetings, traveller, and welcome back to The Register Plays Games, our monthly gaming column. Since the last edition on New World, we hit level cap and the "endgame". Around this time, item duping exploits became rife and every attempt Amazon Games made to fix it just broke something else. The post-level 60 "watermark" system for gear drops is also infuriating and tedious, but not something we were able to address in the column. So bear these things in mind if you were ever tempted. On that note, it's time to look at another newly released shit show – Battlefield 2042.

    I wanted to love Battlefield 2042, I really did. After the bum note of the first-person shooter (FPS) franchise's return to Second World War theatres with Battlefield V (2018), I stupidly assumed the next entry from EA-owned Swedish developer DICE would be a return to form. I was wrong.

    The multiplayer military FPS market is dominated by two forces: Activision's Call of Duty (COD) series and EA's Battlefield. Fans of each franchise are loyal to the point of zealotry with little crossover between player bases. Here's where I stand: COD jumped the shark with Modern Warfare 2 in 2009. It's flip-flopped from WW2 to present-day combat and back again, tried sci-fi, and even the Battle Royale trend with the free-to-play Call of Duty: Warzone (2020), which has been thoroughly ruined by hackers and developer inaction.

    Reuters claims nine State Department employees outside the US had their devices hacked

    The Apple iPhones of at least nine US State Department officials were compromised by an unidentified entity using NSO Group's Pegasus spyware, according to a report published Friday by Reuters.

    NSO Group in an email to The Register said it has blocked an unnamed customers' access to its system upon receiving an inquiry about the incident but has yet to confirm whether its software was involved.

    "Once the inquiry was received, and before any investigation under our compliance policy, we have decided to immediately terminate relevant customers’ access to the system, due to the severity of the allegations," an NSO spokesperson told The Register in an email. "To this point, we haven’t received any information nor the phone numbers, nor any indication that NSO’s tools were used in this case."
