DOAG 2017 Oracle 12c Release 2 Datenbank-Sicherheit in a Nutshell

DOAG Konferenz 2017Below you will find a list of the different demo scripts used during the DOAG training day 2017 Oracle 12c Release 2 Datenbank-Sicherheit in a Nutshell. In general the script do need a SCOTT or a HR demo schema. Some of the scripts may have more requirements eg. Kerberos configuration, Oracle Enterprise User Security etc. The scripts are available free for anyone to use. I do not accept any responsibility for any damage, errors or anything whatsoever caused by running or using these scripts. The scripts have been tested thoroughly but as there are many platforms, Oracle versions and possible configurations, it does not mean that they will work for you when they work for me. Please check the file header for further information on the scripts, references etc before running them especially on production system.

Articles in DOAG Red Stack Magazin

A while ago I wrote two articles for the DOAG Red Stack Magazin. In the meantime both articles have been published. For this reason I use the opportunity to make the PDF versions of the articles available on The articles are written in German and available as Trivadis version as well Red Stack version. Although the articles versions differ only in the number of typos and layout.

None of the articles are currently available in english. On request I will write also articles about Oracle Unified Directory in English in the future. However, currently I still have a lot of ideas for blog posts about database security, enterprise user security and unified directory on my to-do list. And blog posts I usually write in english… 🙂

GDPR and Database Security Speeches

The new EU GDPR and Database Security in general keeps me busy. I’ve updated the list of speeches and events for the next couple of month. It’s an interesting mix between GDPR, Oracle Database Security and MS SQL Server 2016 security. Depending on the feedback of the Call For Papers for the DOAG Conference and the Oracle OpenWorld there will probably be more. But for now I’ll definitely give a full day training on Oracle Database 12c Security at the Education day on DOAG Conference.

Upcoming events

  • Thu

    Mid June I give a lecture on Oracle 18c New Security Features at the SOUG day in Baden.

    The aim of the presentation is to discuss the various security enhancements which has been introduced with Oracle Release 18c. But which features are worth a closer look at? In what context do the new features and option do make sense? How can security be improved in general with Oracle database 18c? Where does it make sense to invest in additional database options? The aim of this lecture is to answer these and other questions around Oracle Database 18c security.

    Among others this presentation will cover the following security enhancements (not conclusively)

    • Create a User-Defined Master Encryption Key
    • Use Encrypted Passwords for Database Links with Oracle Data Pump
    • Use Oracle Data Pump to Export and Import the Unified Audit Trail
    • Create a Keystore for Each Pluggable Database
    • Create Schema Only Accounts
    • Encrypt Sensitive Credential Data in the Data Dictionary
    • Enhancements to Oracle Database Vault
    • Integration of Active Directory Services with Oracle Database
    • Ability to Write Unified Audit Trail Records to SYSLOG or the Windows Event Viewer

    Have a look at the SOUG Webpage for a detailed Agenda of the Event and the location. Looking forward to see you there.

  • Wed

    I present a lecture on Oracle Unified Directory on Docker at the DOAG SIG Security in Stuttgart. Slides and presentations will be in German. Short abstract on my presentations:

    Oracle Unified Directory ist eine All-in-One-Verzeichnislösung mit Speicher-, Proxy-, Synchronisations- und Virtualisierungsfunktionen. Je nachdem welche Deployment-Methode verwendet wird, lässt sich OUD einfach in einem Docker Container konfigurieren und betreiben. Im Rahmen dieses Vortrages werden Punkte rund um OUD on Docker besprochen.

    More Information on the Event including full agenda, registration etc is available on the DOAG web side DOAG SIG Events.

Have you missed an event? In this case check out the download page or blog post categorized with speaking. If possible, I’ll provide all information online?

DOAG Webinar Oracle 12.2 New Security Features

A couple of days ago I’ve successfully finished the DOAG Webinar on Oracle 12c Release 2 new Security Feature. It was a great opportunity to discuss the security enhancements in the latest Oracle database release. This release introduces some new security features that simplify the secure operation of on-premises or cloud-based databases. Especially the online encryption of tablespaces with TDE.

Based on initial experiences and insights, the following topics have been discussed:

  • Authentication
  • Authorization
  • Database Auditing with Unified Audit
  • Encryption with Transparent Data Encryption
  • As well as an overview of further innovations in database security

The slides and the recording of the webinar is available in German over the following links:

EU GDPR, MS SQL Server 2016 and Oracle Security

I’ve just updated the list of my public appearances and planned events. For once, no just Oracle Events 🙂 I’ll speak about the new EU GDPR and its impact on databases in a Trivadis regional customer event together with my colleague Stephan Hurni. Beside this two events I’ll hold a webinar on Oracle 12c Release 2 new security features. This webinar is organised by DOAG.

Unfortunately all these events are in german. No matter, I’m about to register the one or other topic at upcoming Call For Papers. If the speeches get approved I’ll update my list of public appearance.

Trivadis Schwaben Gipfel – Die neue EU Datenschutzverordnung

Just finished my first presentation at the Trivadis Schwaben-Gipfel in Stuttgart together with Florian van Keulen and Aleksander Widera. It is about the new European General Data Protection Regulation (EU GDPR) and some few considerations on its impact on Databases. The slides are available for download  Schwaben-Gipfel Die neue EU Datenschutz Verordnung.pdf.

Some impression for the event and my presentation.


DOAG SIG Security Mannheim 2016

Bit more than two weeks ago I finished my presentation about Security Probleme und deren Risikobewertung at the DOAG SIG Security in Mannheim. It is about Database and Data Classification, Risk Assessment and how Risks could be minimized. The slides are available for download  DOAG_SIG_Security_Security_Wieviel_darf_es_sein.pdf.

DOAG SIG Security

Just a couple of hours ago I’ve lecture a presentation about the latest Generation of Database Technology at the DOAG SIG Security in MĂĽnchen. It is a sneak preview on a few upcoming security improvements. Unfortunately I do not yet have the permission to provide the presentation for download. But I will make the download link available once the dust settles on the latest Generation of Database Technology…

so stay tuned.

SOUG Special Intrest Group Baden March 21st

In about two weeks I will participate at the SOUG special interest group at Baden. I will present a paper entitled “New Security Features in latest generation of Oracle Database“. Where latest generation of Oracle Database does not stand for an other Oracle 11g release. But that’s an other story…

The aim of the presentation is to provide a range of information on new security features as they could be released in with latest generation of Oracle Database. It covers the following possible new features.

  • Data Redaction
  • Unified Datenbank Auditing
  • Role and Privilege Analysis
  • Improved Database Vault
  • Database Application Security Architecture
  • Improved Key Management
  • New OS Roles

Have a look at the SOUG Webpage for a detailed Agenda of the Event and the location. Looking forward to see you there.

Due to the fact that this presentation contains preliminary information, the slides will not be available for download. It is a must to personally attend the SIG SOUG 🙂 If you do not have time to participate at the SOUG event, you have a second chance later this year. I’ve planned a similar presentation for the DOAG Event in DĂĽsseldorf. More on that later.

Oracle Database Security Seminar – New dates

After the two Database Security Seminars in february, Oracle plans two more events in june. I’ll participate with the presentation “Oracle Security – How much should it be?” as already posted in the older blog post Oracle Database Security Seminar – Wieviel darf es denn sein?. The event and presentation is again in german, but there will be a set of slides available in english.

Event Informations

Event announcement and description on the Oracle website.


  • Datendiebstahl – auch bei Ihnen ein Risiko?
  • Aber wie hoch ist das Risiko? Und welche (sinnvollen!)
  • Massnahmen gibt es, um das Risiko zu reduzieren?

Dieser Vortrag präsentiert eine fragebogengestĂĽtzte Herangehensweise an eine Risikoanalyse, anhand deren Ergebnisse die Datenbanken in Security-Klassen eingeteilt (public, intern, vertraulich) werden. In einem zweiten Schritt werden die Risiken pro Klasse definiert – und dazu die Massnahmen, um dies zu reduzierenden. Ziel des Vortrages ist, dass Sie Datenbanken klassifizieren lernen (Sie kennen deren Schutzbedarf und das vertretbare Restrisiko). Ausserdem sehen Sie an einem Praxisbeispiel die Umsetzungen der nötigen Massnahmen.


The updated slides can be downloaded after the event on this website. Slides from the last events in DĂĽsseldorf, Berlin and Basel are already available.
