    Security – nine tips to prevent a virus

    LARGE CYBER ATTACKS ARE WORLD NEWS

    Consider the recent attack with the ransomware virus, which used an email attachment to infect systems. In using the internet, security is increasingly important. At Mett too, online security has the highest priority. How do you recognize a suspicious email? What can you do as moderator to prevent this? A good occasion to discuss a number of tips. We received them ourselves, did some internet research, and asked our security officer Tom Westra.

    HOW DO YOU RECOGNIZE A SUSPICIOUS EMAIL?

    In many cases, it involves private email viewed on corporate computers. This means that your vigilance is required. On first glance, it may appear to be a PDF or ZIP file. Virus emails often have one or several of the following features:

    1. Generic salutation: The email is often not send to you personally, but opens with a generic salutation. You might receive an email from a “company” you don’t even do business with (such as KPN, ABN AMRO, Rabobank) or you’d never want to do ‘business’ with such as the IRS, the police, or a debt collector.
    2. Urgency: The email creates a sense of urgency (if you don’t pay the invoice in time, we’ll send a debt collector after you).

     

    WHAT CAN YOU DO YOURSELF? TOM, OUR SECURITY OFFICER, HAS 9 TIPS.

    Prevention is better than cure. What can you do to prevent yourself opening the attachments of a suspicious email? Tom shares 9 important tips:

    1. Never open unknown attachments

    Never open attachments in emails from unknown senders. Even when it appears that the email was sent by a reputable source. If you doubt the authenticity of an email you received, contact the helpdesk.

    1. Check the sender

    Check the email’s sender. You have to pay close attention here, because language, logos, and fonts are often so similar to real emails, that you can’t tell them apart.

    1. Install a virus scanner

    Install a virus scanner at home. It might go without saying, but a virus scanner is important. You can find good scanners online.

    1. Update your system

    Regularly update your system. Allow applications to update automatically. Do you have a Windows PC or laptop at home too? Check Windows Update for the most recent version and download it.

    1. Work/private

    Keep your work and private life separate. Limit the access children and other family members have to your laptop or PC.

    1. Backup

    Ensure that you keep a backup on an external drive. Creating additional copies of your data is a way to protect yourself. You can either use an external drive or online cloud services. Be sure to at least make backups once a week.

    1. Isolate from network

    If ransomware still found a way to infect your laptop or PC, remove the computer from your network immediately.

    1. Sensible

    Use your common sense.
