Internet Security and Safety

At a recent staff PD session we discussed Internet security and safety. The below videos give some insight to the dangers we face should we not take the necessary electronic precautions.

Stay safe on public Wi-Fi 

1) Only join trusted networks and then be sensible about what you do while away and online

2) Make sure your Firewall is on

3) Turn off file sharing 

4) Avoid using specific websites on public Wi-Fi  ( Banking and personal (Facebook, Twitter, webmail) sites are most at risk since these are the type of websites hackers want access to )

5) Turn off Wi-Fi when you are not using it.

Some other things to remember

  • Have a proper password - at least 8 Characters long; includes numbers, capitals and symbols e.g. eX@mpl3! How safe is your password?
  • Keep your operating software and programmes up to date. These updates patch vulnerabilities within the operating system and guard your machine against exploits. 
  • Make sure your machine is adequately protected against viruses. We use FSecure at the school and can highly recommend it.

Be aware of...

Saving Credentials: You should perhaps only use auto-complete and save your credentials on your own device i.e. don’t do this on any machine that is not your own  

  • Remembering login credentials for you is convenient 
  • Absolutely safe to do for non-critical sites e.g. No banking sites 
  • Credit card numbers, email addresses, passwords and usernames can become vulnerable to attacks 
  • You're likely to forget your passwords if you never have to type them in If you leave your laptop unattended and unlocked, then anyone can retrieve your saved passwords 
  • Fake websites can fool your browser into providing stored login and form data

Ad blocking to prevent click-bait
Install Ad Block Plus plugin for your browsers – Ad block Plus blocks those annoying and maliciously deceptive advertisements found on many of the most popular websites today making browsing faster and safer.

- Adblockplus is available on Chrome, Firefox, Internet Explorer and Safari.

Common ways a PC or laptop get infected (virus/Malware/Spyware)

  • Accepting installation prompts without reading (An Internet advert or window pops-up that says your computer is infected with a virus and needs to scan or that software is required for you to install in order to download something. Or you agree to ‘free software’ that has check-boxes already checked to install additional applications bundled with your download. DON'T accept such prompts. )
  • Visiting / Downloading software/movies/music/pictures from unreliable or illegal sources (Many modern viruses can be hard-coded into the website data which is downloaded into your temporary internet files automatically just by loading the webpage.) 
  • Opening email attachments without knowing who they are from and why you have been sent them. Always double check the sender’s email address and confirm that the mail is relevant. 
  • Plugging infected USB sticks and external hard drives into your laptop without scanning them first.
