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 126.96.36.199, 188.8.131.52, 184.108.40.206, 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. ===========================================================================

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.
I’m more than a little disappointed at people not being serious about information security. One of my customers asked me to help load data from a school system into an apex application I designed for some years back. The excel spreadsheet received from the school system has teacher names and social security numbers. The excel file was not encrypted in any way shape or form. I’ll be contacting the school system on Monday to resolve this issue. If it’s not resolved in a short period of time, I’ll be sending the data to their local news paper. This has got to stop.
Chatting with a friend this morning, we were talking about todo list and being overwhelmed by everything that needs to get done. After sharing with her mindfulness meditation, that helps me keep the “chattering monkeys” at bay and has improved my focus. I mentioned that I’ve gotten away from todo list and now write out the outcome I want from today. Coming up with an outcome for the day can be quite difficult; but once you get the hang of it; the outcome for today will be self evident.
Back on 3/1 I needed to bring this practice back into focus and wrote this note to myself.
In my outcome for the day, I also establish a performance goal for the day. This performance goal can be related to my physical performance while exercising and/or my performance around people. An example of this would be even though my chair is very comfortable, I will do twenty minutes on the rowing machine and lift weight for thirty minutes. It will also include what distance will I do in those twenty minutes, and what weights / sets will I do in my exercise.
My professional outcomes for the day, may be; Catch the problem in production, before the customer catches it. This way, the customer is not surprised when there is an issue. They get an FYI instead of, them sending my team an email saying there is a problem.
The beauty of this is, when you defined the outcome; what you need to do to get that outcome should become self-evident.
If you’re like me, you frequently have many environments open at the same time in putty, sqlcl, sqldeveloper, or other tools. This happened quite a few years back, I was switching between my dev, test, and production environments, doing some work, then the “Oh S^#t” happened. I shutdown production when I thought I was in dev.
You can change your prompt to show what environment you are working in; yea’ that works … but I’ve taken this a couple steps further. Out of habit, if I’m not actively doing work in production, I close it. Second, I changed to colors of my screens to tell me what environment I’m in at a glance. Test is green, dev is blue and production is RED.
This way, if I’m about to do any work in production a cold sweat breaks out and I ask myself, do I really want to do that? You can do this in putty, and sqlcl.
In sqlcl (on windows), bring up the property dialog, click on the color tab, and select your foreground and background colors. Then click OK.
In putty, bring up the configuration dialog. Load the configuration for the environment, click on color under the Window tree, select default foreground, then modify button and select your foreground color. Then select default background, then modify button and select your background color. Go back to session tree and click save.
There you have it, this will make things a lot safer when you have multiple environments open.
I recommend closing your production connection if you are not actively using it. You can’t be too safe.
