Known Attacks. There are two proof of concept attacks published on gethub.com. (I’m not posting the links for good reason.) and there are two known active attacks going on in the wild. ISC SANS and Netlab 360 is tracking attacks.
To Do: 1) Block port 7001 internally until patched.
This is an easily exploited flaw, that allows a user with low level privileges ( connect with network access via Oracle Net) can completely hijack the Oracle database. Affected versions 184.108.40.206, 220.127.116.11, 18.104.22.168, 18
BGOUG: 16-18.11.2018 (planned) Blockchain a primer. There is a lot of confusion about the blockchain. Blockchain is not crypto currency, block chain is the one part of the technology that makes crypto currency secure. We’ll chat about the technology and how to implement the technology.
BGOUG: 16-18.11.2018 (planned) The application of blockchain technologies to build faith and trust in thecriminal justice system. I’m excited about this one. We are going to go through a case study of securing e-justice systems using blockchain technology.
Here is a quick tip on Oracle privilege analysis. Frequently I want to find out all of the ways a user can get to an object for any privilege. DBA_TAB_PRIVS and DBA_ROLE_PRIVS are the two views I go to. I want to also see all the privileges that are granted on any object. This is good for starting at the user tracking privileges to the object, it’s also good for starting at an object and walking back to the user. This query does a pivot on the users and roles to get the path to the object and what privileges are associated with that path. ===========================================================================

WHERE T.GRANTEE = R.GRANTED_ROLE (+)
AND t.grantee != 'SYS'
AND t.grantee != 'SYSTEM'

AND R.GRANTEE != 'SYSTEM' )

Why: That’s a pretty silly question. For me, it’s the opportunity to share what I know with a wide audience. This is one of those conferences where you are not only going to do a serious amount of learning from over 20 of the top speakers in the world. You will also have the opportunity to expand your network. You will definitively have a good time, Kamil will see to that.
How: Get here by plane, train or automobile. I’m told that tickets have already been sold out. But double check with the website, things do change.
When you get here, be sure to bring your thinking cap, your beer mug, and your sense of humor. You’ll need em’. Zobaczcie się za kilka tygodni.
There is a mistake that I’m seeing frequently. Loading a raw data file into an encrypted database then leaving the data file on an unencrypted device.
After loading the data into the database; if you don’t need the data file anymore, you should do a secure delete on the file. If you are going to need the data file again, then move the data file to an encrypted device then do a secure delete on the old data file. Better yet, when you bring the data file down, save it straight to an encrypted device and work from that device.
