Look, for example, at what happened to Estonia last week. Ever since the government of the Baltic state decided (rather tactlessly it must be said) to remove a war memorial to the Red Army from a square in the capital, Tallinn, Russian outrage has ensued.

This took the form of demonstrations and even riots. But then something extraordinary happened: quickly, and wholly without warning, the whole country was subjected to a barrage of cyber-warfare, disabling the websites of government ministries, political parties, banks and newspapers.

Techniques normally employed by cybercriminals, such as huge remotely-controlled networks of hijacked computers, were used to cripple vital public services.

Nato has sent its top cyber-terrorism experts to Tallinn, with western democracies caught on the hop over the implications of such an attack.

The Estonian defence ministry said: “We’ve been lucky to survive this. If an airport, bank or state infrastructure is attacked by a missile, it’s clear war. But if the same result is done by computers, then what do you call it? Is it a state of war? These questions must be addressed.”

TCP/IP serves as the backbone of current computer networks. The reason for this is that it is simple, efficient, and flexible. Like any computer system, the methods it uses are subject to exploitation. Over the course of the last 20 years, as security issues have been raised, counters to electronic attack have been developed: Packet Encryption, Jails, Firewalls, Tar Pits, and a host of others. The evolution of such tools will go hand in hand with the development of methods to circumvent them. IPv6, which was to replace IPv4 with a more secure, reliable and flexible method of data delivery was recently discovered to have a very serious security flaw. This only goes to show that any new “secure” system will always be at risk because the people who design it are human, and will make mistakes.

It is not just the interface translation that is at fault (Firefox or iMax vs Explorer proves that).

The problem is the ability for HTTP itself to be abused and the functions it contains to be used for more nefarious purposes.

Obviously means of defense need to be found, and I expect that many many people are working on that, and many others are working on ways to overcome that defense.

The problem is that the primary network software is from one source.

FWIW…
