Security of Data
The loss and compromise of sensitive data by the Revenue has left most of us dumbfounded as every security precaution that could have been provided to protect this data were totally ignored.
Security professionals across the country gasped in amazement as the story unfolded. If a private company had lost this amount of data the Data Protection Act would be invoked and a criminal investigation and prosecution would follow. Will this happen in this case? I doubt it. Will the truth come out? Again I doubt it particularly as Civil Servants have been told to keep quiet or risk prosecution under the Official Secrets Act.
Government departments with their immunity from prosecution are often cavalier with the rules that apply to the rest of us.
This scandal should bring down the Government or as an absolute minimum result in the sacking of the Chancellor.
However for the law-abiding and professional users of data here are the basic precautions that should be taken when transmitting sensitive data:
These are the basics which seem to have been ignored by the custodians of our personal information.
If the Government is to hold even more data (ID cards for example) then their systems have to be bomb proof.
Industry is adopting ISO27001 - information security management - to protect data and so it should. It is a sad reflection on HMG that these standards are not adopted by them.

However for the law-abiding and professional users of data here are the basic precautions that should be taken when transmitting sensitive data:
- Never send data over the internet unless securely encrypted;
- Never send more data that is actually required;
- If data is to be burned onto CD or DVD, it must be properly authorised and the disks numbered, monitored and tracked.
- Never send disks of this type by post;
- If they need to be sent to another location, a hand to hand transfer is most secure followed by a data tracking delivery and lastly by a registered method.
- Once the disks have been used they should be returned to the originator by a secure method for destruction.
- If there is an apparent loss of disks then an immediate and high priority search should be made and interested parties informed.

Laptop Data Safety
Basic levels of password protection on laptops are easily overcome by the experienced thief and this is causing considerable concern within the industry.
There are two things you should do:
That takes some account of security for the laptop, but with attached devices such as SD cards and USB pen-drives the situation is different:
Anyone stealing the SD Card or Pen-drive can read the data on any computer loaded with similar software. This is clearly a point of vulnerability; the best method to protect this type of device is to encrypt it so that it is useless without the decrypt key.
This protection is not the expensive option it used to be, with open source software freely available. The best of these encrypt and decrypt on the fly and are transparent to the authorised but render the device useless to the thief and in may cases appear to be a blank device.
ISO27001 and Laptop Security
There are two things you should do:
- Physical security - Don't let your laptop out of your sight. Never leave it unattended in a public place. Never leave it in the boot of your car overnight at hotels. Always use a steel cable to attach it to a firm structure when in use outside your normal environment.
- Electronic security - Don't have sensitive data on a hard disk in the first place. Use a complex password and if possible second level authentication, such as a token or other device. When the laptop is on but is not being used, use the electronic lock facility to activate the password entry facility. Use a password on any screensaver.
