International Dimensions

So far we have explored laws in the United States. But many people outside the United States will read this book, perhaps wondering why they should learn about laws from a foreign country. This question has two answers.

International Dimensions

 

So far we have explored laws in the United States. But many people outside the United States will read this book, perhaps wondering why they should learn about laws from a foreign country. This question has two answers.

 

Technically, computer security laws in the United States are similar to those in many other countries: Lawmakers in each country learn about subtle legal points and interpretation or enforcement difficulties from laws passed in other countries. Many other countries, such as Australia, Canada, Brazil, Japan, the Czech Republic, and India, have recently enacted computer crime laws. These laws cover offenses such as fraud, unauthorized computer access, data privacy, and computer misuse. Schjolberg [SCH02] has compiled a survey of different countries' laws to counter unauthorized access.

 

The second reason to study laws from a foreign country is that the Internet is an international entity. Citizens in one country are affected by users in other countries, and users in one country may be subject to the laws in other countries. Therefore, you need to know which laws may affect you. The international nature of computer crime makes life much more complicated. For example, a citizen of country A may sit in country B, dial into an ISP in country C, use a compromised host in country D, and attack machines in country E (not to mention traveling on communications lines through dozens of other countries). To prosecute this crime may require cooperation of all five countries. The attacker may need to be extradited from B to E to be prosecuted there, but there may be no extradition treaty for computer crimes between B and E. And the evidence obtained in D may be inadmissible in E because of the manner in which it was obtained or stored. And the crime in E may not be a crime in B, so the law enforcement authorities, even if sympathetic, may be unable to act.

 

Although computer crime is truly international, differing statutes in different jurisdictions inhibit prosecution of international computer crime. In the remainder of this section we briefly discuss laws around the world that differ from U.S. laws and that should be of interest to computer security students.

 

Council of Europe Agreement on Cybercrime

 

In November 2001, the United States, Canada, Japan, and 22 European countries signed the Council of Europe Agreement on Cybercrime to define cybercrime activities and support their investigation and prosecution across national boundaries. The significance of this treaty is not so much that these activities are illegal but that the countries acknowledged them as crimes across their borders, making it easier for law enforcement agencies to cooperate and for criminals to be extradited for offenses against one country committed from within another country. But to really support investigation, prosecution, and conviction of computer criminals, more than just these 25 countries will have to be involved.

 

The treaty requires countries that ratify it to adopt similar criminal laws on hacking, computer-related fraud and forgery, unauthorized access, infringements of copyright, network disruption, and child pornography. The treaty also contains provisions on investigative powers and procedures, such as the search of computer networks and interception of communications, and requires cross-border law enforcement cooperation in searches and seizures and extradition. The original treaty has been supplemented by an additional protocol making any publication of racist and xenophobic propaganda via computer networks a criminal offense.

 

E.U. Data Protection Act

 

The E.U. Data Protection Act, based on the European Privacy Directive, is model legislation for all the countries in the European Union. It establishes privacy rights and protection responsibilities for all citizens of member countries. The act governs the collection and storage of personal data about individuals, such as name, address, and identification numbers. The law requires a business purpose for collecting the data, and it controls against disclosure. Dating from 1994 in its initial form, this law was one of the first to establish protection requirements for the privacy of personal data. Most significantly, the act requires equivalent protection in non-E.U. countries if organizations in the European Union pass protected data outside the European Union. Chapter 10 contains more detail on this directive.

 

Restricted Content

 

Some countries have laws controlling Internet content allowed in their countries. Singapore requires service providers to filter content allowed in. China bans material that disturbs social order or undermines social stability. Tunisia has a law that applies the same controls on critical speech as for other media forms [HRW99].

 

Further laws have been proposed to make it illegal to transmit outlawed content through a country, regardless of whether the source or destination of the content is in that country. Given the complex and unpredictable routing structure of the Internet, complying with these laws, let alone enforcing them, is effectively impossible.

 

Use of Cryptography

 

Cryptography is the fourth major area in which different countries have developed laws. We survey these laws in a subsequent section.
