How to use your essential PC safely
How to use your essential PC safely
We will introduce things to be careful of to use it safely and recommended actions to take regularly.
Use a supported operating system and software
There is a support period for operating systems and software. After the support period ends, security updates will no longer be provided and you will be using the software in a dangerous state. Be sure to use supported software.
Update your antivirus software to the latest version
Windows comes with an antivirus program called "Windows Defender" installed as standard. Make sure you know how to use it. Make it a habit to check whether it is updated to the latest version and whether any threats are found during scans.
Update your OS to the latest version (Windows Update)
Windows updates (Windows Update) are provided to protect your OS from unauthorized access and cyber attacks. If you are notified of an update, update it to use the latest version of the OS.
Back up your important data
You never know when your PC might break down, so be sure to save important data such as assignments and reports to cloud services such as Google Drive or OneDrive, or to external media (USB).
Use the software in accordance with the license terms and conditions.
When installing software, the license terms will be displayed. Be sure to observe the number of installations and terms of use. Free software also has terms and conditions.
Do not install counterfeit, pirated or illegally copied software
Installing illegally obtained software is a copyright violation. It may also lead to virus infection or unauthorized access. Always use genuine software.
Never open spam emails/Do not click on links (URLs) in spam emails or posts on social media
Do not open spam emails or attached files as you may be infected with a virus. After clicking the link, you will be directed to a malicious web page where you will be asked to enter personal information and the information will be stolen. Delete spam emails immediately. Even if you do click on a link, do not enter any information such as your ID, password, or credit card number if you are asked to do so.
Make sure the free Wi-Fi is legitimate. Do not enter personal information when using free Wi-Fi.
When using free Wi-Fi, there is a risk that third parties may intercept (sneak a look at) your communications. There is also a risk that the contents of emails you send and receive, your ID, password, and other personal information you enter may be collected. Do not enter personal information. There are also fake free Wi-Fi services that look similar to genuine free Wi-Fi provided by stores. If in doubt, refrain from using it.
When using the university's Wi-Fi, please read the network usage rules carefully before connecting.
When using the university's WiFi (LEONET Wi-Fi), please read the rules of use carefully.
Regularly conduct self-inspections regarding information security to check whether it is being used appropriately
Disable browser preloading
To increase page display speed, browsers have a "pre-loading" function that connects to a page and downloads data before it is actually accessed. When this function is active, there is a risk of unintentionally accessing or downloading a large amount of data in a short period of time.
You can disable this feature by changing your browser settings as follows:
By disabling (OFF) this function, you can reduce the risk of unintentionally accessing suspicious sites and unnecessary background communication, which not only reduces privacy and security risks but also reduces communication volume and battery consumption.
| Microsoft Edge | 1. Select "Privacy/Search/Services" from "Settings" 2. Open "Cookies" 3. Turn off "Preload pages for faster browsing and searching" |
| Google Chrome | 1. Select "Performance" from "Settings" 2. Turn off "Preload pages" |
| Safari (Mac) | 1. Open "Safari" > "Preferences" (or "Settings") on the menu bar 2. Uncheck "Preload top hits in the background" in the "Search" tab |
Other notes
Please be aware that there have been many cases of people believing fake security warnings (support scams) displayed on their PC browsers and paying the fees.

How to use your smartphone safely
Here are some tips to keep in mind for safe use of smartphones.
Use a supported OS
OSes have a support period. After the support period ends, security updates will no longer be provided and the OS will be used in a dangerous state. Regularly check the support period of the OS you use and use a supported OS.
Update your OS and apps to the latest version
Using outdated devices without updating them will leave them vulnerable to vulnerabilities (security risks). Always update and use the latest OS and apps.
Use apps downloaded from official websites/Do not download apps from fraudulent websites
Download apps from official websites such as the Apple Store or Google Play. There may be fake apps that look like the real thing. Be sure to check the developer, provider, and reviews before downloading.
Set only necessary permissions for apps / Delete apps that you don't use regularly and review their permissions
When installing an app, always check the permissions you are asked to grant before granting them. Determine whether the app you want to install requires access to your contacts, camera, etc. If the app has unnatural permissions, it is safer to refrain from installing it.
Never open spam emails/Do not click on links (URLs) in spam emails or posts on social media
