Security Policy on using the Centre's Computing Resources

Since incident reports of malicious attacks or account hacking and mail spamming originating from our University have been on the rise, the Computer Centre wishes to make users aware of the "The University of Hong Kong Statement of Ethics on Computer Use".  This article will further substantiate the Computer Centre's policy for legitimate use of our computing resources and state the course of action to take against an abuser of our computing resources.

 For details on how to protect your Unix systems against hacking, please refer to the article "System Security for Unix Systems" in a previous issue of the Computer News.  For PC system security, you may find the experience of a concerned PC user to be useful information.

General Statement

In general, all computer users are expected to behave with ethics in using the University's computing equipment and services.  Any of the following behavior is considered unacceptable and shall constitute an offense or an abuse of computing resources: Please note that  the above guidelines also apply to ACE net/Hall network users using their own computing equipment in connecting to the campus network.  In order to ensure a high level of services to our users, the Computer Centre will monitor the network for sudden surge of traffic or violating activities.

Action against Reported Incidents

When a complaint of abuse of the computing resources is received, the Computer Centre shall handle the incident as follows:
  1. contact the individual to inform him/her of the alleged offense;
  2. suspend the computer account(s) of the offender;
  3. arrange a meeting between the offender and a Computer Centre staff to discuss the incident.  The meeting should focus on educating the individual on the nature of this offense so that future violations can be avoided;
  4. the computer account of the violator will be resumed after the investigation is completed and related issues resolved or when the Computer Centre considers it not a threat to our system's security any more.
If there is a compromised computer system involved in the incident, the computer should be immediately disconnected from the campus network before remedial work can be done on it.  Before re-connecting the machine to the campus network, the violator should be responsible for cleaning up the system based on advice provided by the Computer Centre.  If there is any difficulty in cleaning up the affected system, consultancy services will be provided by the Computer Centre and there may be a charge for such services.  The Computer Centre reserves the right to disconnect a computer system from the campus network if any of the following situations are encountered: If you wish to report any intrusion on your computer system, please feel free to report your case to security@hku.hk.
