Supercharge your compliance practices with SUSE Manager
Many industries and governments require compliance with security standards to ensure security, identity, confidentiality and data integrity. These standards specify a minimum-security level and also mandate measures such as logging and auditing to reveal any hints of unauthorized use.
Some of the most widely adopted standards are:
• Sarbanes-Oxley (SOX)—a U.S. standard intended to improve confidence in financial reporting and accountability of publicly traded companies
• HIPAA—a set of US regulations primarily associated with maintenance and privacy of medical records
• PCI DSS—an independent set of worldwide standards governing credit card transactions
• PIPEDA—Canada’s Personal Information Protection and Electronic Documents Act
• Several European Union directives on data protection and company law
This complicated landscape became even more so in May 2018 with the arrival of the European Union General Data Protection Regulation (GDPR). GDPR, which applies to any organization serving individuals based in the European Union, introduces new compliance requirements for data control, security, due diligence, risk mitigation and breach notifications.
In addition to external regulations, system administrators also have to contend with company policies designed to ensure a minimum level of security, reporting and accountability. Policies might specify an update schedule or declare which versions of which applications are authorized to run on which systems.
The need to scale these external and internal compliance requirements across a whole company can become a massive undertaking that requires significant staff time. SUSE® Manager eliminates the time and expense of compliance tracking by enforcing configuration control, automating auditing and alert notification, locking down package updates, working with Kernel Live Patching and placing all the necessary information at your fingertips.
See It All
SUSE® Manager offers a single user interface for managing the complete lifecycle of all your Linux systems, including virtual machines, containers and bare metal systems running in the cloud or on site. You only need to learn one tool to keep watch over deployments, configurations, upgrades and other significant events in the life of your Linux systems.
The configuration, auditing and automation features of SUSE® Manager make it easy to keep your systems in compliance. You can predefine a complete system configuration and watch for unauthorized changes automatically. SUSE® Manager also checks for vulnerabilities defined through the Common Vulnerabilities and Exposures (CVE) list or OpenSCAP (Figure 1).
Figure 1: SUSE® Manager can quickly check to see if any deployed servers include CVE vulnerabilities.
The powerful tools collected within the SUSE® Manager user interface help you secure your Linux systems and keep them in continuous compliance with external standards and internal requirements. Read on for a closer look at how SUSE® Manager ensures compliance through configuration control, auditing, patch management and security monitoring.
Uniform Configuration with Salt
The Salt configuration management system built into SUSE® Manager enables you to predefine a complete system configuration through centrally managed state files. Whenever a Salt client (called a Salt minion) running inside a managed system receives a state file, it reconfigures the host to make it match the description. Collections of state files that describe complete configurations of systems or services are often bundled as Salt formulas.
SUSE® Manager comes with several preconfigured Salt formulas (Figure 2) and allows you to create custom formulas that can be easily parametrized through ordinary web forms. You can apply formulas to single systems or whole groups. Salt also enables you to execute Action Chains—sequences of actions that implement a complex configuration task but are executed as a single command. Salt formulas and Action Chains let you create a compliant prototype system in a controlled setting and replicate it to other systems automatically, ensuring uniformity and full compliance across the Linux landscape.

You can create an inventory of the contents of your Linux systems, and SUSE® Manager will allow you to easily identify noncompliant software that should not be installed on a system. SUSE® Manager 4 also checks whether all software on the system is up to date, manages patch levels automatically and sends daily notifications listing any noncompliant systems (Figure 3).

SUSE® Manager controls and automates software installations and updates. You can define software channels that group packages by application or use case. A managed system can only receive updates and patches through a secure channel. The channel system in SUSE® Manager lets you guarantee the source of any package or patch installed on any managed system, ensuring that all systems are free of noncompliant software.
Flexibility and Interoperability
SUSE® Manager 4 offers efficient automation to reduce errors and delivery times. Detailed reports are available at every step to verify the state of compliance with external standards and internal corporate policies. You can manage all your Linux assets from a single interface, with automated reporting and improved visualization—regardless of whether those systems are IoT edge devices, containerized workloads, Kubernetes clusters, traditional on-metal servers or virtual machines. SUSE® Manager also includes programming interfaces that let you control the features of your landscape using custom scripts.
Lock Down and Keep Watch
SUSE® Manager automates Linux configuration, patching and management to provide a unified management infrastructure. The SUSE® Manager solution enforces key best practices to ensure compliance through the whole lifecycle of all your Linux systems, from bare metal to containers, for both internal company policies and external regulations. You can specify a predefined configuration and customize it as needed for a uniform and fully compliant Linux landscape. SUSE® Manager also watches for changes that could signal unauthorized access and locks down the package installation process to ensure that only compliant software reaches your network (Figure 4).

You can also use SUSE® Manager to watch for vulnerabilities defined through the CVE list or the OpenSCAP protocol. If you are looking for a way to organize and automate the compliance process to save money and workforce time, take a closer look at the compliance features of SUSE® Manager.
Live Kernel Patching
With SUSE® Manager, you gain even more control over compliance via projects and systems that include live patching. Through this, you can validate that all of your patches work before they are promoted (Figure 5), which allows you to move content independent of system registrations.
Figure 5: Using filters to validate patches for live patching a kernel.
Filters are used to make this happen. For example, you could deny any kernel patch that does not meet a specific time frame or filter out any patch that would require a reboot. This lets you make sure a build won’t fail because of a problematic patch. In the case of live patching, you can define the time period for a specific kernel lifecycle with live patching and control when you want to reboot.
