General IT advice
Turn off your PC when finished
To help reduce energy consumption, please switch off your PC and monitor when they are not in use. This saves the University energy and money, for example leaving a computer switched on overnight for a year will produce enough CO2 to fill a double decker bus.
Every NTU associate has a quota on their mailbox. If you receive a message saying you are running low on space, please try to save any large attachments on your H drive. Any messages in your deleted items will still count towards the size of your mailbox.
Password change policy
The University has a password change policy to ensure that passwords are updated at least every 90 days. Please do not write down any passwords, as this is a security risk.
Phising emails and how to detect them
Phishing is the fraudulent practice of sending fake emails in order to obtain personal details or passwords for criminal purposes. We will never ask you to confirm your password. Unsolicited messages received from banks or financial organisations are often fake.
The authenticity of an email can often be established in some or all of the following ways:
- Look at how the email addresses you, non-specific salutations such as Dear Member or Dear Valued Customer are unlikely to be from a valid sender. If the messages were from a legitimate source, they would address you by name, customer number or other specific detail.
- Also be wary of emails asking you to update your details, or to log into your account via a link within the message. The link may appear to take you to the company's website with the usual login screen but these are often fraudulent. Check to see if the webpage is secure by looking for a locked padlock symbol, or HTTPS at the beginning of the address.
- Most web browsers now have phishing filters that we recommend you use.
What to do if you are unsure about an attachment that has been sent to you?
- Run a virus scan on the document by copying the file to your desktop, right clicking on the file and selecting scan for viruses.
- If you are still unsure, you can email the file to the Service Desk who will be able to help you further.
What to expect if your PC detects a virus
You will receive a pop-up message from Microsoft Forefront Endpoint Protection, stating that 'detected threats are being cleaned' and 'no action needed'. If any other behaviour is exhibited please email us for further advice and support.
Use your personal home drive
Information Systems recommends that you store all personal files in your home directory (the H:\ drive). All files stored on this drive are backed up overnight. If you store any files in the My Documents folder, or other areas of your computer’s local hard drive, and the hard drive fails you will lose all of the files stored on your PC.
