Why Now: How CyberSaint is Making Automated Risk Assessments Possible with NLP

Emerging technologies are shaping the future of every industry. Whether that’s through Artificial Intelligence and robotics transforming the way humans interact with the world, or ever-evolving “things” that are being embedded with sensors and software (hello, Alexa and Google Home) that strive to make every aspect of your life “smart”. Technology moves so fast that it’s vital for product leaders to have their fingers on the pulse of various emerging technologies and their potential impact. These technologies support market expansion, allow better differentiation of products and services, and enable providers to be more competitive and efficient.

One of the ways CyberSaint uses emerging technologies is through Natural Language Processing (NLP). NLP’s ultimate objective is to “read,” decipher, and understand language that’s valuable to the end-user. Currently, there are several ways NLP is used in day-to-day life. Many are familiar with chatbots, or auto-complete in emails or texts. But there’s a gap in cybersecurity and integrated risk management where NLP could be used to inform risk and regulatory compliance. Since interactions between humans and machines are based on language processing, NLP allows organizations to process increasingly large amounts of data, granting them the ability to be more efficient, more risk cognizant, and more secure.

Kyverno vs. OPA: Modernizing Your Kubernetes Policy Management by Ritesh Patel

Ever since Kubernetes emerged as a top-contender for multi-cloud container management, automation and security challenges have been holding back the adoption of this innovative solution. This is sparking a new revolutionary technology: Kubernetes policy management engines. These policy engines allow for the automation and secure handling of Kubernetes configurations — essentially restricting what applications can run within a given cluster.

A few years ago, the best way to manage security within Kubernetes systems was through the use of Role-Based Access Control (RBAC). However, RBACs were unable to provide adequate oversight at the level of specific resources, meaning intervention at higher levels is not possible. Pod Security Policies (PSPs) were designed as a built-in solution to provide cluster-level security. PSPs enable fine-grained control over the authorization and update of different pods. Unfortunately, the decision has been made to deprecate the use of PSPs due to complexities in the understanding and configuration of these policies.

Currently, the consensus on how to properly manage Kubernetes policy comes down to one debate: Kyverno vs. OPA. Both Kubernetes policy management engines are developed to help enforce management policy across stacks; however, they have some significant differences. For C-suite executives and high-end stakeholders to make informed decisions, it’s important to understand exactly what you’ll get from Kyverno vs. OPA.

But before we get to that debate, let’s go over the exact function of a Kubernetes policy management engine.

Kubernetes and Policy Management

As enterprise companies continue to adopt hybrid- and multi-cloud systems, there is an increasing need to manage the different containers that are being used to house various components of their digital infrastructure. This management system needs to operate across public and private clouds, centralized servers, and other critical infrastructures. This is where Kubernetes comes into the picture.

Kubernetes uses declarative programming to understand, compare, and modify any discrepancies between a container’s observable and desired states. Essentially, it ensures that all programs are running according to a user’s preferred policies and, if they aren’t, can rectify issues through internal logic.

But as these systems continue to increase in complexity, a higher-order solution is needed to manage all of the Kubernetes policies enacted across the multi-cloud infrastructure. This need resulted in the development of two distinct policy engines that can be leveraged to manage policies in a Kubernetes environment. The first, OPA/Gatekeeper, is a general system that operates independently of applications to manage their policy decisions through a specialized programming language. Kyverno, on the other hand, was created specifically to manage Kubernetes policies and is written in an easy-to-use native language.

Open Policy Agent

OPA is a general policy engine that can be leveraged across Kubernetes, Envoy, and other container environments. OPA was initially developed as an engine applicable for systems outside the realm of Kubernetes and then adapted to include the container management system upon its development. Gatekeeper is the specific webhook built on the OPA project used to manage policies in Kubernetes environments.

By decoupling policy management from the domain of specific codes, each software can be specified in a declarative way, and decisions offloaded from the individual systems themselves. The OPA/Gatekeeper engine allows for the validation and mutation of different resources. Each policy decision begins with a request, known as a query, which OPA processes through a specific declarative language known as Rego.

While incredibly well-suited for application across any container management system, the custom Rego language is not Kubernetes-native. This means all relevant DevOps teams will need to invest additional time and resources to gain proficiency in a new programming language before they can apply OPA Gatekeeper for Kubernetes policy management.

Kyverno

The younger of the two police management engines, Kyverno, has been developed as an answer to the highly complex, overly demanding nature of OPA Gatekeeper. Originally developed by Nirmata and now part of CNCF sandbox projects, this Kubernetes policy engine provides DevOps departments with a host of benefits — from its Kubernetes-native design to its ability to generate policies.

In response to the complex task of learning the OPA’s Rego language, Kyverno is designed specifically to use Kubernetes-style composition. This means that its policy expression capabilities provide users with a higher degree of simplicity and flexibility while enabling the development of more powerful policies. This Kubernetes-native design also makes Kyverno highly compatible with the dynamic configuration, GitOps, and tools commonly applied in a Kubernetes environment.

Policy engines are created with key capabilities that enable them to validate and mutate policies as needed. Kyverno, in addition to the validation and mutation functions that OPA Gatekeeper performs, also has built-in generation capabilities. Generation rules allow for supplementary and supporting resources every time a resource is updated or created.

Kyverno vs OPA: The Decision

At the end of the day, the decision regarding how best to modernize your Kubernetes policy management will come down to the specific criteria of your enterprise operations. For digital infrastructures comprising multiple different DevOps teams that require the development of complex policies, OPA Gatekeeper may be the right solution. But for any company that is singularly dedicated to the use of Kubernetes for their container management needs, Kyverno is unparalleled in its ability to modernize policy management processes. As it currently stands, CIOs leveraging Kubernetes as their predominant container management solutions can benefit greatly from the application of Kyverno as their policy management engine.

Twitter Considers New Security Features | Avast

Twitter People Experience Designer Lena Emara tweeted 4 new Twitter security feature concepts, asking users for feedback on whether or not they should move into development. “Privacy is one of those things everyone wants, but it’s not a one-size-fits-all,” Emara tweeted, before going into detail on each idea. The first idea, “Replies,” gives users an easy way to make their tweets public if they’d like to make a response to a non-follower viewable. The second idea, “Account Breadcrumbs,” provides easy and quick switching between multiple profiles. “Privacy Sets,” allows users to pick from various security presets, depending on their needs. The final idea, “Discover Me (Or Not),” alerts users when someone searches their username. It also lets users choose whether or not they’d like to be found that way. “These are just ideas and not being built (yet), so your feedback is helpful!” Emara wrote.

o MicroLogix 1100: All versions

3.2 VULNERABILITY OVERVIEW

3.2.1 IMPROPER INPUT VALIDATION CWE-20

A remote, unauthenticated attacker sending specially crafted commands could
cause the PLC to fault when the controller is switched to RUN mode, which
results in a denial-of-service condition. If successfully exploited, this
vulnerability will cause the controller to fault when the controller is
switched to RUN mode.

Agriculture, Water and Wastewater Systems
o COUNTRIES/AREAS DEPLOYED: Worldwide
o COMPANY HEADQUARTERS LOCATION: United States

3.4 RESEARCHER

Beau Taub of Bayshore Networks reported this vulnerability to Rockwell
Automation.

4. MITIGATIONS

A controller in this fault state can be recovered by downloading a new project
or an offline copy of the project to the controller. Rockwell Automation
recommends users set the controller switch to RUN mode to prevent remote
programming. Users are encouraged to have a backup copy of the project in the
case it is necessary to recover from an event. Rockwell Automation also
recommends users should consider migrating to the Micro870 controller.

Rockwell automation recommends the following general security guidelines:

o Utilize proper network infrastructure controls, such as firewalls, to help
ensure EtherNet/IP traffic from unauthorized sources are blocked.
o Consult the product documentation for specific features, such as a hardware
mode switch setting, to which may be used to block unauthorized changes,
etc.
o Block all traffic to EtherNet/IP or other CIP protocol-based devices from
outside the Manufacturing Zone by blocking or restricting access to TCP and
UDP Port 2222 and Port 44818 using proper network infrastructure controls,
such as firewalls, UTM devices, or other security appliances. For more
information on TCP/UDP ports used by Rockwell Automation Products, see
Knowledge Base Article BF7490
o Use trusted software, software patches, antivirus/antimalware programs and
interact only with trusted websites and attachments.
o Minimize network exposure for all control system devices and/or systems and
ensure they are not accessible from the Internet. For further information
about the risks of unprotected Internet accessible control systems, please
see Knowledgebase Article PN715
o Locate control system networks and devices behind firewalls and isolate
them from the business network.
o When remote access is required, use secure methods, such as virtual private
networks (VPNs), recognizing that VPNs may have vulnerabilities and should
be updated to the most current version available. Also recognize that VPN
is only as secure as the connected devices.
