Multi-level Security

Last updated:

In the modern world, a lot of information inside of a single company can have different levels of importance for said company. This kind of importance grading also implies different security measures that have to be applied to specific parts of the data – but drawing a clear line between different categories might not be an easy task. Luckily enough, a dynamic Multi-Level Security (MLS) solution can help solve this problem.

While this particular problem is not as bad when it comes to a single company with no outside connections whatsoever – pretty much each and every company has to share information and/or collaborate with multiple partners on a regular basis, using different types of media and different problems. Information sharing is the main reason for comprehensive data security controls to exist in the first place.

As we’ve mentioned before, creating an effective security system that still allows for information sharing is not an easy task – which is why various MLS solutions exist. Combined with dynamic policy enforcement, MLS is capable of doing high-level data security without restricting data sharing, but still stopping any unauthorized access to the data in question.

A security classification for a specific piece of data refers to how much damage can unauthorized exposure of said data piece bring to the company. It is quite normal for a company to have information that belongs to different security classification levels. Each level of security classification is associated with its own freedoms and limitations, the main purpose of which is to control who can access this particular data piece, who can share it, and so on.

But these kinds of security controls only work when the data in question is mostly stationary and barely moves anywhere – which is absolutely not the case for most of the data in the modern world. This is where we have to be aware of the concept of security domains – a specific part of information protected by some sort of a security boundary.

It’s not an easy task to maintain the same level of security when the data in question is constantly moved between different security domains (with each domain having its own set of rules, security measures, and so on). Each company has become a very complex entity that needs some sort of dynamic policy enforcement to be able to solve some of these problems in the first place.

A solution to this particular problem is MLS – a complex security system with the ability to dynamically enforce different security rules to different data categories within the same environment. MLS also offers granular controls for these security measures to work across different security domains, as well as data labeling, dynamic policy enforcement, and more.

However, MLS on its own is not at its peak performance, either. To be able to act and provide access to specific parts of the data at a granular level, the inclusion of Attribute-based Access Controls (or similar) is pretty much a requirement, too. ABAC is capable of improving MLS effectiveness by acting as an extended policy enforcement method with the capability to provide even more context to each data access attempt based on a multitude of rules and regulations.

ABAC can serve as an easy way to assess each user and their devices to make sure that they meet the requirements to access specific parts of the data. The data itself can also be classified using a multitude of parameters, such as location, organization, device type, nationality, and a lot more. This makes it way harder to access information that you should not have access to, for any of the reasons.

The combination of MLS and ABAC can be incredibly beneficial to a company, offering a multitude of advantages and benefits, such as:

  • Better access management for more sensitive information thanks to the addition of contextual labels;
  • Improved effectiveness and interoperability due to the possibility of multinational information sharing and the usage of mission-specific environments;
  • Higher speed and accuracy of giving a specific information to a user, if the latter meets the requirements to access it;
  • Easier document creation due to the security rules being set for the data in question automatically, and more.

If you’re looking for an example of a platform that is a combination of MLS and ABAC, look no further than Kojensi platform by archTIS. It’s a highly effective SaaS solution that helps with protecting various information types without hindering the ability to collaborate, share data and store it.

Other than the aforementioned multi-level security features, Kojensi also offers an abundance of additional features, including:

  • Metadata modification for specific files or documents, restricting access to them even more;
  • Support for multinational information sharing via security handling agreement mapping from different nations;
  • An easy-to-use interface that helps with both editing documents and enforcing security rules;
  • Easy control and establishment of various virtual workspaces, with extensive user control;
  • Better security for newer documents due to an easy way to instantly change the document’s metadata, granting it specific terms of access right after its creation – and more.

There is also another product of archTIS that can provide a similar set of controls and regulations, but focused mainly on Microsoft applications – it is called NC Protect. It is capable of working with several different M365 applications, including Teams, SharePoint, OneDrive and Exchange, allowing for a much more detailed and specific rules enforcement for your Microsoft-based data. 

NC Protect offers a variety of sharing, usage and access controls for different environments, and the effectiveness of both these solutions is backed up by archTIS being a known player on the market for the last 15 years.
