What you can do to protect yourself

Here are some steps you can take to protect yourself from cyber attacks.

  • Be on the lookout for suspicious links, attachments, and downloads
    Malware and ransomware can be embedded in links, attachments, and downloads. Make sure a link is authentic before clicking on it.
  • Create and use strong passwords
    You should always use strong and long passwords that are difficult to hack. Use unique passwords, meaning a different one for each account. Passwords should be at least 8 characters in length and contain numbers, special characters, and capitalized letters.
  • Use multi-factor authentication whenever possible
    Multi-factor authentication adds an extra layer of security. If a service you are using offers multi-factor authentication, use it.
  • Use secure internet communications
    Use sites that use “HTTPS” if you will access or provide any personal information. Don’t use sites with invalid certificates.
  • Update your anti-virus software regularly
    Make sure your anti-virus software is up to date and updates are installed regularly.
  • Report anything suspicious to your IT department
    Report any suspicious emails, files, or links to your company’s IT department.
