Sending Yokogawa FAST/TOOLS logs to McAfee ESM

Collecting logs from Yokogawa FAST/TOOLS and sending them to McAfee ESM could be complex due to this unique combination of log sources and the SIEM solution. In this post, we will look at how you can forward log data from Yokogawa FAST/TOOLS to McAfee ESM using NXLog.

Yokogawa FAST/TOOLS

FAST/TOOLS is Yokogawa’s SCADA software platform. Its client-server architecture comprises three main functional components: a SCADA server, a Web HMI client, and a Web HMI server. The SCADA server is responsible for collecting, processing, and managing the logs it receives from the Web HMI clients. The Web HMI server displays events and other operational data from Web HMI clients while also serving as the human-machine interface for displaying the logs that the SCADA server has processed.

FAST/TOOLS comprises several function-specific modules that include OPC server and client functionality and a history scheduler. The FAST/TOOLS software platform integrates with cloud computing and virtualization infrastructures. It is widely deployed in the oil and gas industry and large manufacturing plants worldwide.

Collecting Yokogawa FAST/TOOLS logs

FAST/TOOLS produces a wide variety of logs about its operations. These logs are available in flat files and stored in the C:\Users\Public\Yokogawa\tls\log\ system directory.

There is no room for error or trade-offs because Yokogawa FAST/TOOLS monitors and controls the type of operations Its steady, uninterrupted operation is essential to maintaining plant safety. However, due to excessive log noise, valuable information can sometimes remain hidden in the logs it collects. Another challenge is the lack of consistent log formats. The ability to parse data from various log formats is an absolute necessity.

NXLog Enterprise Edition is a lightweight, modular log collection tool capable of tackling the most challenging cases log collection may pose. Its rich features allow it to read almost any log format and parse fields to produce structured data for further processing. It is the perfect tool for monitoring and collecting FAST/TOOLS logs.

RDBMS data collection

FAST/TOOLS provides an ODBC (open database connectivity) interface that collects data from the FAST/TOOLS data set services layer and sends it directly to an external ODBC compliant database. With FAST/TOOLS, you can view table components and perform faster queries, obtaining much quicker insight into your plant operations. FAST/TOOLS includes an embedded relational database management system (RDBMS) that allows you to execute more complex queries and cross-reference FAST/TOOLS data with your own RDBMS environment.

Collecting FAST/TOOLS logs from file

FAST/TOOLS' file-based logs include start logs, diagnostics logs, system monitor logs, and systems error logs. The processes that detect system errors send messages to the FAST/TOOLS unsolicited message handler (UMH), which manages all the necessary information present in these logs. This information includes the name of the process that detected the error, a timestamp, and an error code. You can view these application error logs in the messages.umh file of the FAST/TOOLS data directory. NXLog is capable of parsing these complex logs by using regular expressions.

FAST/TOOLS passive network monitoring

FAST/TOOLS supports open platform communications (OPC) functionality and includes an embedded OPC Unified Architecture (UA) environment. It also supports classic OPC for distributed communication (DCOM) links across your network. NXLog can passively monitor your network traffic and generate logs for most network protocols.

NXLog’s data normalization and log aggregation capabilities can extend the functionality of Yokogawa FAST/TOOLS. Because NXLog can collect logs from literally any file in any format, it is ideally suited for integrating with FAST/TOOLS' wide variety of log types and file formats.

The log sources mentioned above and NXLog’s features play an important role in normalizing logs to meet McAfee ESM’s requirements.

Sending logs to McAfee ESM

McAfee ESM is a SIEM solution that collects, processes, and correlates events for investigation and incident response. It offers real-time visibility into all activity on systems, networks, databases, and applications.

Log sources

A log source must be added for McAfee ESM to receive events from NXLog. ESM provides a long list of predefined log sources that it can accept, such as DHCP server logs, DNS debug logs, Windows Event Log, to name a few. Each log source type must have a corresponding data source (or parent source) configured in the ESM local receiver.

Forwarding logs

NXLog uses its om_tcp and om_ssl output modules to forward processed logs to McAfee ESM via TCP and TLS/SSL, respectively. TCP is suitable if ESM is installed on the local network, but if installed in the cloud, like in AWS, it is vital to use TLS/SSL for securing data that leaves the local network.
