Computer Security Guidelines for Users

• Back up your data regularly.

• Use strong passwords. In particular, blank passwords should never be used.

• All machines must be registered to use the wired (cabled network).

  • Only the registered IP address may be used.

  • DHCP must be used for configuring IP addresses.

• Operating System(s) must have automatic updates enabled.  Sophos Anti-virus and Remote Update must be installed.

• All instances of viruses should be reported to CSI Help.

• Ensure that a password is required to log on to your machine.

• When the machine is unattended (e.g. evenings, weekends), ensure that you are logged out or have locked the machine so that a password is required.

• All services / applications installed should be secured.

  • Only required services should be enabled.

  • Any additional required updates must be installed.

  • Any additional security tools should be run.

• A firewall should be installed where practicable.

• File-sharing (peer-to-peer) software should not be used except for research purposes.

• The regulations for the use of computer systems and networks in UCD are available from UCD IT Services. Non-compliance will be viewed as a breach of policy leading to a possible loss of network services. The University has implemented an Intrusion Detection System to enhance the security of the network, and machines found to be in breach of the regulations will be removed from the network. Regularly check this page and UCD IT Services for security information.

• Send any security queries to CSI Help.
