Windows Server 2003 has officially reached it’s end-of-life date. Does this mean that all of your Windows Server 2003 servers will be hacked on July 16th? Probably not. However, it is worthwhile to ensure that your organization has a plan in place to migrate all of your applications and services off of this legacy operating system. This is especially true if you have any Windows Server 2003 systems that are exposed to the internet. It is only a matter of time until a new vulnerability is discovered that affects this operating system.
As a former Windows Systems Administrator, I understand how difficult it can be to convince an application owner to invest the time and resources into migrating a system or service to a new operating system. Despite the fact that these systems have a heightened risk of being compromised, it’s very possible that your organization doesn’t have the financial resources to migrate your applications and services to a new operating system. You’re not alone. I found over 1.3 million servers running IIS 6.0 in Shodan. Over 688,000 of these servers are in the United States. However, there are still ways to reduce the risk of hosting these legacy operating systems until a migration plan is put into place.
A few ways to reduce the risk of hosting an application on a legacy operating system are:
- Discover and document – You can’t protect a system if you don’t know it exists. Take some time to identify and document all of the legacy and unsupported operating systems in your network.
- Learn about the application – Take some time to learn some details about the application. Is it still even being accessed? Who uses it? Why is it still hosted on an unsupported operating system? Are there other options available?
- Educate the business users – If financial resources are an issue, take some time to explain the risks of hosting this application to the business users. Once they gain an understanding of the risk associated with hosting their application on a legacy OS, they can help secure funding to ensure that the application is upgraded.
- Isolate – Segmenting the legacy system can reduce the risk that it is accessed by an attacker. It also can decrease the likelihood that a compromise of the legacy system will spread to other servers.
- Update and secure – Install all available patches and updates. Not only for the operating system, but the hosted applications as well.
- Perform thorough log analysis – Implement some sort of centralized logging platform to ensure you have the ability to detect any anomalies that occur within these systems.
- Plan for the worst – Be prepared. Have a plan in place for responding to an incident involving these systems.
