Information security standards have become increasingly important in recent years, as more and more legal requirements oblige companies to demonstrate a certain degree of cybersecurity compliance. The IEC 62443 family of standards describes in its various sections the requirements for the secure implementation of an ICS (Industrial Control System) and represents a guarantee of cybersecurity in industrial environments. This article deals with IEC62443-3-3 covering cybersecurity of industrial systems.
The increase of malware specifically designed to run on systems that support industrial processes creates a need in the industry that can be partly covered by different technological solutions. This article will focus on the different options available on the market to detect malicious files that aim to modify the operation of industrial environments or simply cause denials of service.
Both portable and agent-deployed solutions can be an option, and this article will reflect on these and other options as well as provide guidelines on when it is best to use one solution or the other.
When a security incident occurs in an ICS (Industrial Control System), depending on the severity of the incident, it can generate a serious problem, both at a productive and economic level, as well as in the security of the people working in the industrial system.
Therefore, in this article following the one entitled "Good practices for the recovery of industrial systems (I)", response plans will be discussed from a point of view oriented to current regulations, as well as their applications and necessity in critical industrial environments, such as the energy sector.
When a security incident occurs in an ICS (Industrial Control System), depending on its severity, it can generate a serious problem, both at a productive and economic level, as well as in the security of the people working in the industrial system.
Therefore, in this first article of a series on this subject, we will explain precisely the recovery plans, some general guidelines for their development and some conclusions on the use and applicability of these plans.
Technical reporting is one of the most important parts of the completion of a task, as it reflects the results of all the work done. Moreover, it does not only constitute a final deliverable for a customer, or for the decision-makers within an organization, but also acts as the link between the person or team that has carried out the task and the decision-makers, based on the findings.
Currently, there is a constant evolution in the technologies and implementations made in Industrial Control Systems. On one hand, some of the most common implementations for the improvement of industrial systems infrastructures are digitalization and the use of cloud technology. On the other hand, the increase in communication protocols and IIoT devices (due to the growth of the Industry 4.0) generates a large volume of traffic that is difficult to control and secure.
The programming of PLCs is a fundamental part of the initial phases when building and designing industrial plants. About that environment, the company will base all its operations in that environment making the configuration of these controllers a critical element. When it comes to programming these devices there are a series of steps and best practices that take advantage of the native functionalities available and that involve little or no need to resort to a PLC programmer, protecting the device in a simple way with minimum spend on resource.
Organisations are exposed to the consequences of cyber threats, and may be ill-prepared to face and manage cyber incidents, whether provoked or unprovoked. For this reason, in 2014 INCIBE launched its Indicators for the Improvement of Cyber Resilience (IMC) model, with the aim of improving and understanding the state of cyber resilience in organisations.
Demilitarized zones, also known as DMZs (demilitarized zones), are used for the secure exchange of information between computers on a network that we want to protect and an external network that needs to access those computers. DMZs are widely used in the IT sector and also in the OT sector, but the equipment and services they host are not exactly the same.
The security of control systems can be threatened from different aspects, with the end device being the most important attack vector. With this in mind, the IEC, within the 62443 standard, wanted to emphasise devices by preparing a document exclusively concerning their security: IEC62443-4-2. This document contains different technical requirements to improve the security of the types of assets that can be found in a control system.
