Security for you and your device

Keep your device and information safe by following these best practices – 

  • Do not leave your device unattended – if you have to leave it, lock it up so no one else can use it; same for a flash drive or an external hard drive – encrypt and lock. Desktop computer – lock the screen and shut down the system when you are not using it.
  • Password management – maintain strong unique passwords and change them several times during the year;  do not use the same password for multiple sites – allows hackers to get your password for everything ☹
  • If you receive an email or see something suspicious on your computer STOP  and call Sierra – do not forward or reply to the email and do not click on any attachments or hyperlinks!
  • Phishing scams – unsolicited requests for personal information, which are done mostly by email, but can also be done by text, phone or social networking sites; do not fall for any email message or phone call asking for financial or personal information.
  • Malware – do not click on websites you do not know or download software from sources you are not sure of or do not trust, as they could host malware that will install on your computer and do harm. Do not click on unexpected email attachments, or a website you are not sure of as it could be embedded with malware.
  • Credit and debit card fraud – a lot is done online with spyware collecting personal information in the background recording your Internet browsing habits and keystrokes.  Card information can be stolen from unsecured websites – do your research and be sure the site is legitimate. Sites having “https” in the web address or a lock icon is meant to symbolize higher security.
  • Ransomware – if you do not want to have to pay a sum of money to get access to your computer be leery of malicious software and malware.
