Make sure your private information is not exposed. Your disk still has all your information even if you delete the data. When you delete information from your disk, what happens is the index pointing to your data is deleted, your data is still on the disk. If you’re like me, you have photos, documents, and emails. I don’t know about you, but I don’t like people reading my private emails to friends, customers, and acquaintances.
Blancco and data recovery company Ontrack performed a study of 159 disk drives purchased on ebay. Ontrack recovered information from 42% of the drives. Now, personally I don’t sell my used equipment; however you might do that. There is an easy and safe way to sell your old devices and not worry about exposing your information to strangers.
I use the free version of CCleaner. (Note: I have not received any compensation for this, it’s just the tool that I use) CCleaner has the ability to securely delete information on the disk and also keep your disk from getting cluttered with junk that windows does not clean up. Personally I run this about once a week.
When you select wipe free space, You’ll get a popup window that will tell you the process will take a long time. So, this is not something you want to run on a regular basis. When I’ve run it in the past, it has taken three days to run on the 1T drive in my laptop.
Once you’ve installed CCleaner, select Options, then under settings select the Secure Delete and in the pulldown select how secure you want your deletion. I use Advanced Overwrite 3 pass, this is pretty secure. This option will overwrite your deleted files three times with random data and if you select wipe free space, it will overwrite your free space three times with random data.
This year has been busy, and I don’t see it slowing down anytime soon. Life is good. The my chapters are all finally in for the Database Security book, now it’s time to edit. After reading the audit chapter, I’m not really happy with it. Once I’m done editing it, the version APRESS gets back may not look a lot like v0.1.
This May my travels are going to take me to Kiev Ukraine, Chișinău Moldova, Helsinki Finland, Stockholm Sweden, back to Kiev, and home just in time to celebrate my 59th birthday (am I starting to get old?). I’ll be speaking in Helsinki at the Full Stack Developers Conference on PL/SQL Secure Coding Practices https://fsdc.fi/ then heading over to Stockholm to do a couple talks on Holistic Database Security, Secure Coding Practices, and discuss Privilege Analysis.
June is going to be a bit easier, I’ll be in Bulgaria for BGOUG to talk about Privilege analysis and Leadership; then back to Chișinău and Barcelona to take care of some business.
July, oh, that’s simple, back to Bulgaria again (third trip there this year) where I’ll be speaking at the IEEE International Conference on Software Quality, Reliability, and Security. https://qrs19.techconf.org/track/tutorials The topic, Database Secure Coding and Design.
I’m going back to my speaking roots in May. Oracle Users Group Finland gave me my first opportunity to speak on database security many years ago.
This year we’ll see some of my favorite speakers in Helsinki.
First up, Heli From Finland. (she uses that because nobody can pronounce her last name.) Feel free to try at her last name Helskyaho, bet you can’t pronounce it either. Some of the things you may not know about Heli, she was a ballerina, travels more than me, and loves to show people her city Helsinki, is an Oracle ACE Director, and a PhD student. This year, she’ll be speaking on “The Basics of Machine Learning.”
