Security advisories
We care about your network security. It’s our highest priority, and it’s what drives us to deliver the timely, useful advice on emerging vulnerabilities that you’ll find below. But there are also a few practices that it’s good common sense to follow at all times:
- Change the default password as soon as you log in to a new device for the first time
- Use strong, unique passwords for every device and change them regularly
- Ensure your devices are running the latest available firmware
- Don't enable remote access unless it's absolutely necessary
