Software Transformation

Remove dead code, unused libraries, and bloat without requiring access to source code.

Protocol Customization

Identify, disable, and remove unwanted and rarely-used legacy features of networking protocols.

Model Driven DevOps

Automate and scale network configuration functions with software- defined networking (SDN) tools.

Realtime migration between Instruction Set Architectures (ISAs)

Seamlessly and automatically migrate applications between x86 and ARM architectures.

Container Hardening

Reduce attack surfaces and common vulnerabilities and exposures while optimizing efficiencies.

Legacy applications, when not optimized, have become massive cost centers, depleting resources, power, and personnel.

Software Transformation

While AI, machine-learning, event-driven software architecture, and other types of automation tools represent the latest trends in technology, the reality is not so glamorous. A significant number of organizations, from government agencies to large corporate enterprises, are still tied to legacy applications that play a critical role in their respective operations. Enter PJR’s software transformation tool designed to address the issues that often plague legacy applications, costing organizations millions in terms of:

  • Higher Sustainment Costs
  • Difficulty Patching and Removing Known Vulnerabilities
  • Not Yet Exploited Security Vulnerabilities
  • Slow Execution
  • Lack of Scalability, Flexibility
  • Increased Power Consumption
  • Poor Interoperability with Modern Technology
  • Poor Customer Experience/Service
  • Negative Impact on Employee Morale

Java DeBloat Video

Java DeBloat Video

Reduce your legacy application’s footprint by 20 to 60% without compromising features or functionality.

Software Transformation: removes dead code and features without needing to access source code or the original developers.

PJR’s software re-engineering system uses dynamic and static analysis to generate a call graph of the application, then applies slicing algorithms and cutting techniques to safely remove bloat and allow the user to selectively remove unwanted features from the compiled binaries. This results in smaller, simplified applications with less vulnerability.

Communication protocols represent a critical component of your technology infrastructure – and can result in significant issues for your organization.

Protocol Customization

Just like software, communication protocols can suffer bloat from numerous sources, such as support for legacy features and rarely-used/unnecessary functionality.

This bloat can represent significant problems to any organization, from increased security vulnerabilities to unstable communications and slower networks.

PJR partnered with a university to develop a protocol customization tool to identify, disable, and remove unwanted features of protocols. PJR takes a multi-pronged approach in simplifying protocols and maximizing their optimization:

  • Protocol Feature Identification
  • Feature-to-Source Code Mapping
  • Automated Removal/Disabling of Features From Source Code

Less complication. Fewer security issues.
More speed and stability.

Protocol customization can address protocol risks and issues as they relate to mobile ad hoc networks,
heterogeneous wireless networks, adaptive routing, reliable network transport, decentralized service operation and discovery, network management and monitoring, and cognitive network technologies.

Your network forms the backbone of your information and communications technology, from cloud computing, to AI, to edge computing – and an ability to customize protocols could improve security and efficiency.

Model Driven DevOps

With the ever-increasing demands placed on datacenters and other large-scale computing environments with the arrival of IoT, AI, and mobile computing, the need to create frameworks that can support more data-intensive applications is significant.

Model Driven DevOps (MDD) provides a means to leverage and scale existing networks to meet these demands, and more. . Automate and scale network configuration functions quickly, consistently, and securely using Infrastructure as Code (IaC)

MDD is the solution is the SDN solution network engineers have sought to handle the most critical networking tasks:

  • Network Scalability
  • Uptime
  • Centralized Network Provisioning
  • Holistic Enterprise Management
  • Centralized Security
  • Lower OpEx/CapEx
  • Unification of Cloud Resources
  • Data Traffic Control

As network complexity increases, organizations can either increase the support staff to manage the network, or deploy tools that absorb the increased complexity without the need for additional resources.

By automating a range of network configuration functions, MDD accelerates the delivery of new services, scales them in concert with demand, and replaces manual tasks with automated, repeatable processes.

Being limited to a single-processor architecture limits flexibility, locking an organization in to x86_64 processors and potentially being exposed to increased power/cooling requirements and additional security risks.

Popcorn

Enterprise-class software systems are comprised of millions of lines of code. As they undergo hardware refreshes in their current and emerging baselines, they are challenged with multiple degrees of complexity. This complexity results in significant and costly overhead to update/maintain; not to mention the security vulnerabilities exposed in such legacy systems.

The availability of ARM-based processors, Graphics Processing Units (GPUs), Data Processing Units (DPUs), AI accelerators is exploding, and Popcorn,, developed using Popcorn Linux (Popcorn Linux – Home), enables applications to “pop” over to another ISA (and vice versa) without execution interruption. These emerging compute platforms are designed for specific types of applications and can be expensive and draw a lot of power.

Save money. Save power. Save time.

This has numerous benefits across the technology landscape:

  • Developers can take advantage of the benefits offered by next-gen processors without rewriting applications from the ground up –potentially saving millions or even tens of millions of dollars.
  • Server density can be increased as ARM processors require less power/cooling.
  • Security posture can be improved.

Container Hardening (CONFINE)

Confine Video

Confine Video

The adoption of the open-source container platforms and third-party libraries provides significant cost benefits, but it also presents various security challenges. Containers can be exploited by an attacker using system calls to gain root access to systems operating on the tactical edge. Hackers can spoof/steal data, install malware, snoop network traffic or otherwise highjack systems.
Previous container attack surface reduction efforts rely on dynamic analysis and training using realistic workloads, and consequently are not practical or comprehensive. CONFINE only uses dynamic analysis to monitor the container to identify applications and relies on static analysis to identify the system calls used by those applications.
