combining two domains in SE Linux

To get the maximum value out of my writing when I am asked a question that is of general interest in private mail I will (without in any way identifying the person or giving any specifics of their work) blog my reply. I hope that not only will this benefit the general readers, but also […]

more security foolishness

Dutch police arrested 12 people for acting suspiciously on a flight to India. A passenger said “They were not paying attention to what the flight attendents were saying”, I don’t pay attention to the flight attendents either. When you fly more than 10 times a year you learn how to do up your seat-belt and […]

2006 Open Source Symposium

There is an interesting eWeek article about this that contains the interesting quote “The built-in locks don’t yet meet TSA specifications because […]

a newbie question about SE Linux and anti-spam measures

An anti-spam measure that is used by a very small number of people is that of verifying the sender address by connecting to the sending mail server. For example when I send mail from russell@coker.com.au the receiving machine will connect to my mail server and see whether it accepts mail addressed to russell@coker.com.au and will […]

invasive vs inconvenient security

The recent news from the UK gives us an example of invasive security. Preventing passengers carrying on any hand luggage (even wallets) and frisking all of them is the type of treatment you expect for criminals and visitors to maximum security prisons. It’s not what you expect for people who are involved in routine (or […]
