Morefield Communications Cybersecurity and IT Operations team have been carefully monitoring a new vulnerability in the Log4J Java library which provides logging capabilities to various software. This new vulnerability (Log4Shell) allows a remote, unauthenticated attacker to force Java-based applications and servers to log a specific string into their internal systems, if using the Log4J library. When the application or server processes the logs, the string can force the vulnerable system to download and run a malicious script from an attacker-controlled domain, effectively taking over the vulnerable application or server.
A significant number of applications are affected. We will be updating this post as new information and affected applications are discovered.
Listed below are some of the running list of all applications and/or server products affected:

We expect more application vendors to report this vulnerability and we are diligently monitoring vendor responses for platforms and systems commonly deployed. We are committed to helping our clients make smart technology decisions while delivering outstanding service and expert solutions. If you have any questions, please contact your Network Administrator or Sales Representative.
Cloud computing is, in essence, storing or using programs and data using the internet instead of an on-site system. But one cloud computing model may be vastly different from the next. The term covers a range of cloud models, types and services, each tailored to meet various technology needs for individuals and organizations.
While the variety in cloud computing services is vast, these applications are categorized into three different deployment types — public clouds, private clouds and hybrid clouds. So what is the difference between private, public and hybrid cloud computing?
Below, we’ll discuss the key features of each deployment type and the advantages and disadvantages of each. With those features in mind, you can then choose what’s right for your organization.
Public clouds are the most commonly used cloud computing deployment type. In this model, a third-party cloud service provider owns, operates and manages all cloud resources, including hardware, software, servers and other infrastructure items. The services are then delivered to remote users over the internet.
In a public cloud model, all cloud users, also called “tenants,” share the same cloud resources. Each tenant’s data is separated and isolated from other tenants’ data, and they can use individual logins to access their data from a website or application. Public clouds are often used in cases where there are predictable computing needs. They can host web-based email services, office applications, storage services and testing environments.
While individual public cloud models can be used for a variety of purposes and can offer numerous capabilities and features, there are some characteristics shared across public cloud services. These key characteristics of public clouds include the following:
Public cloud examples vary by provider. General providers tend to offer great availability and numerous integration options, while smaller ones can provide more customization options for specific applications.
Private cloud hosting solutions are also known as internal or enterprise clouds. In this model, the cloud is proprietary and is dedicated to a single organization. The cloud platform may be hosted on-site in the company’s data center or in an off-site, third-party data center.
In a private cloud model, the company owns and manages its own cloud platform on a private network. Instead of having a third party own and manage the infrastructure, the business handles it all itself. This structure allows the company to have exclusive access to its own cloud platform. But the company is also responsible for managing, maintaining, securing and updating the data center.
Private clouds are highly customizable since the organization can make adjustments freely to serve its unique needs. It can also enjoy greater security since it does not need to worry about sharing resources with other companies. Companies using the private option can also apply any number of security features to protect their cloud platform.
While private clouds vary widely in their specific features based on the needs of the companies using them, some common characteristics include:
So what are the examples of private cloud applications? Most commonly, companies working in highly regulated industries that require tight security and handle sensitive data will use private clouds. Government agencies and financial institutions, for example, will often use private clouds to manage sensitive information.
A hybrid cloud platform is effectively a marriage of public and private cloud computing. Hybrid clouds orchestrate on-premises and third-party resources by connecting an internal data center with a public cloud. The hybrid cloud then allows the user company to deploy data between the private and public clouds as needed.
As computing and processing needs change, hybrid cloud platforms let businesses scale up their private cloud infrastructure. They can move overflow into a public cloud instead of purchasing more equipment for their internal infrastructure. Companies can then select what types of data must stay internal and what workloads can be moved to the public cloud. This choice allows for greater flexibility and scalability while still maintaining security for regulatory requirements.
Some key characteristics of hybrid cloud computing include:
A common example of a hybrid cloud is an organization using a private cloud environment for their workloads. It combines that with a public cloud resource to handle peripheral workloads following a spike in computing needs. Hybrid clouds are an excellent choice for companies with strict regulatory requirements or those that have fluctuating workloads.
Each cloud computing type has its own key features and characteristics. But what are their relative benefits and challenges? Below are some of the key advantages and disadvantages of each cloud type and what they mean for potential applications.
Public clouds hosted by third-party service providers offer a range of advantages to users, including:
These benefits make public clouds an excellent resource for small to medium-sized businesses with limited IT budgets.
While the public cloud offers many benefits, some of the potential drawbacks of public clouds can make it an unviable option for certain types of businesses. Some of the primary disadvantages of public clouds include:
Some of these disadvantages do not present problems to certain industries or business types. But they can be a deal-breaker for businesses working in highly regulated industries like healthcare and finance or larger companies.
Now that we’ve looked into the pros and cons of public clouds, what are the benefits of private cloud models? Some of the most popular advantages of private cloud models include:
These advantages make private clouds a top choice for highly regulated industries and businesses that need greater control over their IT resources.
While private clouds offer numerous advantages in terms of compliance and control, there are some challenges that make it a less viable option, especially for smaller businesses. So what are the disadvantages of private cloud models? Some of the potential ones include:
These possible disadvantages can make private clouds an exclusive option, as they are too limited for a portion of business ventures.
Hybrid clouds present a unique option to businesses, combining the capabilities of the public cloud with the security and control of private clouds. Some of the major advantages of hybrid clouds include:
These advantages make hybrid clouds an excellent option for mid-size to large businesses that need a balance of flexibility and security.
While hybrid clouds get around some of the more common issues with both private and public clouds, this model still comes with its own set of challenges. Some of the common drawbacks of hybrid cloud models include:
Quality implementation and assistance from specialists in cloud computing technology can help mitigate some of those challenges.
Learning about the different types of clouds gives companies greater insight into the options available, but it inevitably leads to the question of which to choose. Is the public or private cloud better, or would a hybrid cloud be the best choice for your application? When considering the different types of cloud computing models, think about your company’s needs and whether a specific model would support your business. Below are a few key factors to consider:
