I will describe how you configure trust stores for the WebLogic Server.
Chain of trust
When a SSL server certificate is issued by a CA it is signed by a another certificate. Normally this will be an intermediate certificated, that is again signed by the CAs root certificate. So there is a chain of trust between the (more...)
In every business, there is a balance between business goals and various impediments.
You need to make sure that you don’t allow legal, QA, security and other internally-focused concerns tip the scale towards paralysis. There is more in this week’s edition of my newsletter “Technology That Fits” – sign up here.
Suddenly, our offshore colleagues could not access the database. We scrambled to find a solution, and and it soon transpired that the central security function had rolled out out a security policy upgrade the night before. Unfortunately, our offshore colleagues were connected to the network in an uncommon way, so the new security policy cut them off.
You don’t know what will happen when you change a system. Enterprise IT landscapes have reached a complexity (more...)
This post is about exploring the mechanisms used by Oracle Clusterware 184.108.40.206 to restrict remote service registration, i.e. the 12c new feature "Restricting Service Registration for Oracle RAC Deployments"Why is this useful?
This improvement of 12c clusterware and listeners over the 11.2 version is useful mainly for security purposes, for example as a measure against TNS poisoning attacks (see also CVE-2012-1675
), and it is particularly relevant for (more...)

I recently got my hands on a review copy of Learning Devise for Rails
and was quite interested to see if it was worth a recommendation (tldr: yes).
A book like this has to be current. Happily this edition covers Rails 4 and Devise 3, and code examples worked fine for me with the latest point releases.
The book is structured primarily as a (more...)
We recently upgraded our EM12c 220.127.116.11 installation to 18.104.22.168. This service was configured to authenticate logins against our Active Directory server via LDAP. However, after upgrading we found that authentication stopped working, even after recreating the Active Directory Authenticator (as required). I could see the list of users from AD, but could not authenticate them in EM!
In this post I'm going to share what we did to diagnose (more...)
There has been a policy in integration that has stored up a really great challenge of data security, and by great I don't mean 'fantastic' I mean 'aw crap'. Its a policy that was done for the best of reasons and one that really will in future represent a growing challenge to Big Data and federated information.
The policy can be described as this:
Users authenticate with Apps, Apps
Today when trying different settings with Basic Authentication and SOA Suite, I wanted to from the embedded OWSM Policy Repository of JDeveloper to the one stored on the application server. In JDeveloper you can do that through preferences (Tools | Preferences). See this blog for more details.
Click on the App Server Connection option and choose an existing connection through the Connections drop-down or add a new one by clicking New.
It seems that Boing just lost a 4 billion dollar deal to supply fighter jets to Brazil, because the Brazilians were miffed that the NSA spied on them.
You also live in a transparent world. If the NSA was unable to weed out Edward Snowdon in their hiring procedure, do (more...)
My son (10) has been asking about VPNs a lot lately. Which I thought was because of all of the news lately about the NSA. I ended up showing him tunnel bear, which he quickly installed on his laptop and iPhone. I complimented my son for his interest in security (more...)
It appears that international credit bureau company Experian was inadvertently selling private information to online criminals posing as “private investigators”. These criminals then used Social Security numbers, birthdays and drivers license records to commit identify theft. Ironically, Experian is also selling protection against identity theft to private customers…

Java 7u51 is scheduled for release in January. It will have some consequences for you Forms installation that you need to address.
As far as I know there is no problems with using 7u51 on the server side, only on the client side.
7u51 requires you to sign all RIAs (Applets and Web Start applications).
Oracle already signs the standard jar (more...)
After input from Jacco H. Landlust and Edwin Biemond I have rewritten my post about entropy.
In computing you often need random numbers. They are used for encrypting stuff but also for lots of other things.
For Linux servers random numbers are default provided by the /dev/random device. /dev/random is a pool of random bits (more...)
Tired of tracking down all the users in the database to deactivate them when they cease to exist, or change roles, or fulfill their temporary need to the database? Or, tracking down privileges you granted to existing users at the end of their requested period? The solution is to think (more...)
If you have been working with Oracle 12c, you may have missed a little something that appeared without mush fanfare but has some powerful implications. Let's see it with a small example--connecting with SQL*Plus.C:\> sqlplus arup/arup
SQL*Plus: Release 22.214.171.124.0 Production on Mon Aug 19 14:17:45 (more...)
2 days ago I gave a presentation “Oracle 12c from the attackers perspective” at the DOAG SIG Security. I learned some interesting things, especially that a fix for the Oracle oradebug “disable auditing” problem is available since 9 months.
Oradebug allows to run OS commands and to enable/disable Oracle SYSDBA (more...)
While I was not surprised that the U.S. intelligence agencies monitor web activity, I was surprised at the scale revealed by the Edward Snowdon leaks.
If there are still American cloud providers that do not routinely provide the NSA with wholesale access to their customers’ data, it will only (more...)
Here is a quick way of creating your own CA and issue server and client certificates via OpenSSL.
I will test the certificates via the Apache HTTP Server by configuring one and two-way SSL.
I use Oracle Linux 5.
You should of cause only use this for test scenarios.
