Today is my MBP's first anniversary of being baptised... 26 April 2016. I remember the morning very well. How could I forget?!
I'd brought in a pint of water to my desk, set the glass on the desk near my open laptop, I sat down and promptly knocked the glass over baptising my Mac and flooding my keyboard. I near froze, horrified at what I had done. Ran into the next room to get a towel, sat down and put it on my knee, lifted the Mac upside down over it watching the water pour then drip from the keyboard. Then I realised the Mac was still on. So turned it right way up to turn it off and it conked out! What could I do now?
Panic ensued. Needed to hang it upside down... couldn't think how and what with. But then remembered there was a metal framed laundry basket that had material I could hang the Mac over. Left it there while I went online on another computer to search what to do. I was slightly comforted that I wasn't the only one who'd done something so stupid!
I decided to leave it hanging... occasionally I turned a hair dryer on in a warm setting and directed the airflow gently over the keyboard.
Time for a walk... it would be a while before I attempted to switch it on. While I walked, I wondered what would I lose if it didn't come on... and came to the conclusion, very little, except my pride:
- backup was only done the previous day so the contents of the hard disk would be restored
- I was developing a web site early that morning and all work was on one of the server instances (we use AWS cloud hosting service).
So I was more relieved... the disciplines of backing up and our development processes we'd formed over the last two decades had counted for something! It was a matter of waiting.
When I got back I continued to use the hair dryer to gently evaporate any water that was left and dry it out. The next morning I figured it was time. Put it on my desk, gingerly switched it on and, to my amazement, everything started up as normal. Tested every key and every one worked.
So was there any lasting damage? No, when we opened the Mac to upgrade it recently, we only found the natural fluff that gets into any computer, was in corners, obviously directed there from the air of the hair dryer.
These days there are so many other measures we need to adopt to prevent sensitive data loss or device compromise in every day scenarios -- business or personal. These include using public wi-fi services when out or travelling, or allowing a stranger to watch us using our keyboard or view our screen, or worse still, losing a laptop or phone, even temporarily. So it's important to do more than backup your devices regularly. Other measures include:
- making sure you have to log in to your computer when powered up
- making sure it goes to sleep if left idle for a few minutes and require password to revive
- preferably make sure all data on your laptop is encrypted
- don't leave laptop where it could easily be stolen
- ensure your backup is encrypted, or the data is secured in another way
- physically secure your backup device
- don't use laptop on an insecure wireless network
- protect sight of your screen if using in a public place, always close lid if not using
- use different passwords for different services
- use two factor authentication whenever possible
- be very careful about what you view, download or execute.
Many organisations decide to implement the standard ISO 27001 (Information Security), in order to benefit from the best practice it contains to reassure themselves and others that its recommendations have been followed.
Hope you found this useful and will help you think about what backup and discipline procedures you could improve.
