1. Keep your access codes confidential and do not to lend them out to others.

Access codes are strictly for personal use, and may not be lent out to others.

• System administrators are not allowed to ask you for your access codes under any circumstances.
• Lending out access codes to third parties is prohibited. Surfnet, UvA-net's parent network, prohibits the use of its network by third parties.

There is no need to lend out your access code to fellow students or colleagues: they have been issued their own access codes.

2. Make sure to choose passwords that are not obvious, and change your password regularly.

For example, choose a password made up of the first letters of a sentence you find easy to remember, and change one or two letters into characters. ‘I hardly ever eat cabbage anymore' would then become Ihe!ca. Keep in mind that specially designed software can be used to find out your password by means of password guessing if you choose anything obvious. Your username and password must always be different.

3. Make sure to save your data on the server rather than your PC as much as possible.

Saving your data on the server will limit damage to your files in the event of a major incident: backups are made of all files you save on the server, which is more effectively protected against viruses and other threats than your own computer.

4. Take precautions to prevent computers from being hacked.

• Activate a password-protected screensaver on your computer.
• If possible, use a firewall on your PC at home, and regularly install updates of your operating system.
• Do not install or activate unnecessary software applications.
• Never engage in hacking, cracking, spoofing, defacing, cross-site scripting, portscans, sniffing and denial of service attacks.

5. Do not engage in activities in violation of any law, including copyright law.

UvA employees and/or students may not use UvA-net to engage in activities that are in violation of any law. UvA employees have a relationship with the UvA subject to employment law, and may be subject to additional rules on the basis of their collective labour agreement.

6. Do not distribute discriminatory, defamatory and/or offensive material.

In spite of freedom of expression, there are limits to what is deemed acceptable. Make sure to observe proper conduct. Remember to treat others as you would wish to be treated.

7. Do not install and/or use illegal and/or undesirable software.

This includes software for which the required licensing fees have not been paid and software that disrupts normal operation of the computer and/or UvA-net. Software applications such as Kazaa are not illegal, but the consequences of their use almost always are.

8. Do not distribute computer viruses, etc.

• The term computer viruses should also be taken to include worms, Trojans, etc.
• If you are using UvA-inbel or UvA-ADSL on your PC at home, install at least one antivirus program and make sure to regularly update your anti-virus files.

Be careful when opening attachments and programs found on the Internet.

9. Do not send unsolicited emails; do not generate unnecessary amounts of network traffic.

• Do not participate in ‘chain mails' no matter how valuable their message may seem. Peace on earth won't be achieved by bombarding others with email messages.
• You may not send out anonymous emails or emails with an incorrect sender address (spam).

10. You may not use your UvA-net connection for commercial purposes.

UvA-net is property of the UvA. In the case of abuse, users may be denied access to ICT services, including UvA-net. Employees found guilty of abuse may be subject to dismissal.

Compliance

All persons granted access to UvA-net must abide by the ICT code of conduct described above, which was drawn up by the UvA Board and which forms an integral part of the UvA-net Regulations. Violation of one or more of the rules in this code of conduct may result in the user being denied access to UvA-net for a period determined by or on behalf of the Board. This period will be no longer than one year. The period may be extended in the event of repeated violations.
