advocate a hybrid solution combining traditional with cloud-based. When could this be beneficial?
The answer to your question is specific to your business and network environment. While I can't answer it for you, I can offer a number of considerations to keep in mind when you contemplate replacing your traditional firewall with a cloud firewall. Here's what enterprises should ask themselves:
- What are our current information risks? Are parts of our information systems at increased risk because we're using a traditional firewall? For example, are we more susceptible to denial-of-service attacks or malware infections because the traffic has not been sanitized before reaching our network?
- Do we have the resources to focus on internal firewall management and monitoring? Is time or cost related to monitoring prohibitive?
- Is the firewall outdated and in need of replacement? How does the cost of that replacement compare with an equivalent (or superior) cloud firewall service?
- Are we qualified to ensure our internal firewall is properly configured and maintained?
- Are there particular cloud firewall vendors that can help solve our problems?
- Have we asked prospective vendors the tough questions such as:
- What happens when your firewall goes down?
- How do we know how secure your firewall and overall cloud environment is?
- Will you help us in the event of a security breach? To what level?
- Can we have access to the logs for forensics or archiving purposes?
- How do you inspect traffic protected by SSL?
While I'm sure it exists, I can't imagine a situation where a cloud firewall could eliminate your on-premises firewall altogether. This may be why many security pros are advocating for a hybrid approach. In a hybrid firewall environment, enterprises keep their traditional firewall (perhaps simplifying the rule base) but also work with a cloud firewall vendor to serve as an intermediary for specific services or applications. Enterprises can then maintain control while leveraging the scalability, denial of service protections and presumed redundancy of cloud-based firewalls. In my opinion, it's a win-win.
