Linux Software Security and Compliance - Atomicorp - Unified Security Built on OSSEC

Secure Linux and Apps With XDR Plus Compliance

Free and open source Linux runs servers, desktop distributions, commercial mobile devices such as Android and Nokia, and virtualized server environments like Kubernetes clusters and containers. Linux even runs supercomputing. Accordingly, Linux skills are in high demand, both for software application development and for API and kernel level security.

Whether you’re a do–it-yourself open source shop or an IT solution provider for the enterprise open source and government sectors. Atomic OSSEC has your needs covered in one integrated security solution. The powerful commercial endpoint and cloud workload protection system provides deep open source-based detection, response, and expert support, enabling your organization to orchestrate security and compliance across popular and custom Linux applications. 

Linux Security XDR

Linux System and Application Security

To secure Linux applications, you’ll need to be able to tweak the Linux source code. There’s the free Linux kernel, but there are also specific open-source programs you’ll want to use. Providers include Ubuntu, Rocky Linux, Red Hat Enterprise Linux (RHEL), and Red Hat Linux-as-a-service resellers. 

Atomic OSSEC protects Linux (including end of life deployments), servers, applications, major cloud platform environments, and web and cloud APIs. It provides strong control, detection and response for Linux platforms and open source applications down to the kernel. Atomic OSSEC supports multiple Linux distributions like Red Hat, Ubuntu and Rocky Linux servers (legacy and latest versions) and virtual server applications. It can monitor and secure workstations, clusters, containers, and other software applications. 

The Atomic OSSEC endpoint and cloud workload protection system enables you to deepen and extend protection and response to support all types of Linux use cases:

  • Linux enterprise applications. Linux is deployed in modern virtualized server environments including VMs, multitenant servers, and containers and clusters. It also runs on equipment, old and new, where Linux software or Linux-based commercial software is embedded. Atomicorp is an active Linux security developer for modern and legacy system applications. If the equipment or OS version doesn’t modernize, the security still should. Security functions need to go beyond AV and basic protection, and Atomic OSSEC offers a deep and agile Linux security stack. 
  • Business services – As IT adapts to changing business and market needs, security can’t be an afterthought when rapid service development and deployment occur. Security engineering should start in the early stages of software development and continue through the service lifecycle so that rollouts of new hardware, virtual servers, clusters and containers are protected and in compliance with security and privacy regulations. Our DevSecOps software protects Linux environments (modern and legacy) at the kernel, OSI, web server, and application service level with powerful detection, precision, and response. 
  • Web application development – Secure the software and services used to enhance the customer experience on websites, web browsers, and web applications. Atomic OSSEC intrusion prevention and active response looks into file characteristics and anomalous details across devices, source code, programming languages, and log utilities, old and new.**
  • Enterprise data and analytics – Meet security and privacy requirements such as GDPR, HIPAA, and PCI DSS as you responsibly analyze big data and customer interactions for smart decision making and investment.
  • Enterprise data services – Implement, manage and secure your Linux databases, files, directories, and connective endpoints, on premise, remote, and in the cloud. Orchestrate powerful but network-noninvasive security rules to detect, respond, and report while enabling authentic traffic flow and file access.
  • Managed IT services – As part of a managed IT service offering, Atomic OSSEC contributes cross-platform detection, response, and threat hunting, real-time FIM, vulnerability management, search, auditing, reporting, and more. Reduce software maintenance cycles and costs and log management duties, while addressing risk and compliance requirements.

Secure Linux Systems and Data for NIST, PCI DSS and Other Compliance Requirements

Protect your computing endpoints, the software supply chain, the federal supply chain, customer data, and cloud and web workloads in compliance with federal, global and industry regulations and standards. Atomic OSSEC helps to meet the following standards:

NIST. National Institute of Standards and Technology (NIST) 800-53 is a catalog of security controls to which Department of Defense contractors and subcontractors of federal agencies must adhere. The NIST 800-171 subset provides guidance specifically to federal agencies to safeguard controlled unclassified information (CUI). Atomic OSSEC weaves OpenScap and SCAP and Red Hat Ansible security automation capabilities into a network-noninvasive toolset rich with advanced security capabilities and NIST compliance controls. It goes deep into Linux architectural resources and disparate connective endpoints in the cloud and software supply chain to detect and respond, monitor and protect data. 

FISMA. Atomicorp enables your organization to address Federal Information Security Modernization Act (FISMA) requirements. These include the ability to: 1) identify threats and vulnerabilities, 2) protect digital assets, 3) detect malicious code and behavior, and 4) respond through automation and strong Linux security expertise. Atomic OSSEC also enables you to 5) recover through immutable redundant backup (it automatically stores a copy of every changed file before it was changed), and 6), report through a GUI and audit controls that provide artifacts for compliance and reporting.

FIPS. Federal Information Processing Standard 140-2 (FIPS 140-2) is a requirement for U.S. government organizations and contractors, a government security mandate designed to evaluate and approve encryption solutions serving the federal supply chain. The Atomic OSSEC intrusion detection system is fully FIPS 140-2 compliant out-of-the-box and provides government agencies, independent software vendors, and equipment vendors with additional tools for assessing, implementing, and enforcing FIPS encryption compliance elsewhere on any system on which the agent is installed.

JSIG. Federal agencies and commercial organizations supporting the federal Department of Defense’s IT, and any organization in the supply chain, must comply with the Joint Special Access Program Implementation Guide, or JSIG. This means tightened rules over control, no matter what the device or equipment, or where. Atomicorp provides deep and versatile endpoint and cloud workload detection and response across a variety of operating systems, new and old, to help organizations, agencies, and system integrators address JSIG security controls. 

DISA STIG. DISA STIG is an implementation guide for organizations working for the DoD. The DISA STIG guidelines outline how an organization should handle and manage security software and systems, and information assurance. Atomic OSSEC fortifies enterprises and agencies with powerful endpoint protection and audit controls to meet these STIG guidelines as well as NIST-800-53 and HIPAA requirements. Atomic OSSEC also leverages SCAP and OpenSCAP automation capabilities to facilitate rapid and effective security orchestration.

PCI DSS. Credit card information is the bloodstream of business operations—but a sought-after item by thieves and adversaries. Harden the security at the financial transaction and data handling stages as to who can be trusted with this full information, or a piece of it. Atomic OSSEC provides evolving security rules for your PCI DSS compliance, protecting systems, files and data across AIX, Linux, and Windows OSs, and legacy environments such as Linux end of life (RHEL 5, 32-bit), Windows end of life (XP, 2003, etc.), HP-UX, Solaris, Ubuntu, IoT Linux, and CentOS.

HIPAA. Health care organizations and patients run a gauntlet of data hijackers as they exchange data in distributed fashion. The bad guys appear in the form of cyber thieves, men in the middle, and fraudsters persistently trying to intercept this data for illegal purposes. HCOs have a lot of devices to protect inside and outside facilities, and many don’t have sufficient personnel or budget to track and control where private data is going and how it’s being used. This can bring HIPAA violations, fines and test a health care organization’s confidence. Atomic OSSEC provides automatic logging, advanced security control rules on data use, and compliance reporting and analysis tools to address HIPAA §164.312(b), the section of the HIPAA Security Rule that governs auditing and monitoring. 

GDPR. In General Data Protection Regulation (GDPR), the European Union laid out rules on how personal data must be kept private and sovereign by anyone doing business in European Union countries. Atomic OSSEC software aids in GDPR by inspecting traffic and payload on server, workstation, and in the cloud. It empowers organizations to enforce processing restrictions over network resources and IT services, and extend authorization and authentication capabilities over private data and personal files being shared locally and in a distributed manner.
