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...)
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...)
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…
Do you know (more...)
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...)
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.
It is now possible to protect Apache on both Windows and Red Hat servers against CRIME SSL/TLS attacks.
I have updated my Hardening the Apache HTTP Server post accordingly.
Often you do not want servers in your internal network segments to be able to access the Internet directly.
One way to get controlled access to the Internet is to place an Apache HTTP Server in a DMZ network segment. Internal servers can then use the Apache server as a (more...)
Oracle’s “Security Alert Advisory for CVE-2012-3132” issued a warning about an attack vector that once again was discovered by security expert David Litchfield. The vulnerability allows to execute SQL code with SYS privileges by using object names containing quotation marks, if the attacker has authorized access to the database, has CREATE TABLE and CREATE PROCEDURE privileges […]
It is not difficult to create an SSL/TLS certificate and configure an Apache HTTP Server to use it. But I found that there are some things you need to know that does not necessarily make much sense. Here are some lessons learned and a couple of tips.
Intermediate and Root (more...)
These are some amazing statistics…
If you do a default installation of the WebLogic Server user activity is not audited. WebLogic has a build in Auditing Provider but it has to be enabled.
The Audit Provider can log these events.
To enable it via the Admin Console got to Security Realms => myrealm => Providers (more...)
I bet if any of you have an exposed server to an internet connection, without properly firewall protection, that your server is under heavy fire from hackers around the “world”… By the world I mean mostly China and Russia ssh attacks. If you’re curious, on Linux you can check the (more...)
I was interviewed for a nice article about database security on Dark Reading. The interesting question, I think, is not wether to invest in DB security. To me, it’s a given that you have to do it (even though some customers still don’t agree). The question is – how will the threat landscape change if [...]
