Businesses have long known of the threats of DDoS to their operation, and the security community has been watching this threat evolve to the point where we all need to take collective action to prevent attack.
- Businesses of every size need to know what devices you have and what you have them for. This gets hard but must be done if you are to optimize your IT. If you don’t understand what you have got you will never be able to keep systems patched and will have a hard time changing default passwords.
- We are strong believers in using software defined perimeter approaches to understand who is who and what is what and only allowing authorized actions in your network.
- Use a DNS firewall to reduce two major issues: 1) users visiting sites known to have malicious code that threatens your enterprise and 2) malicious code inside your enterprise that seeks to beacon out to its controller. We recommend Verisign’s DNS Firewall. It provides cloud-based network security based on is built on Verisign’s global recursive DNS platform.
- Managed DNS is important as well. Make sure your provider of managed DNS services has a track record of reliability.

- Ensure your workforce is tracking the cyber threat by signing up for the OODA Daily Pulse. This will provide strategic warning of threats and info on mitigation strategies.
- Your network defenders should avail themselves of the powerful research tools of Passive Total. This will help keep them aware of threats in ways that will help them adjust defenses. A key benefit is tracking risks that exist totally out of your control.
