Can i install ics on playbook
In a best-case scenario, a specialist in ICS security has written some guidance for her to follow. These playbooks instruct her to gather and analyze relevant data, how to triage the alert, and how to determine if the activity monitored was malicious or benign.
A good security operations environment provides playbooks for many tasks — both routine and emergency. Not only does this aid each analyst in performing tasks they have less expertise in, but it ensures every analyst completes tasks uniformly and can reach a similar conclusion.
Playbooks are tools which help security analysts perform their job in a consistent way, while learning more about IT and ICS security in the process. The Dragos Platform places a heavy focus on playbooks for both hunting and incident response. Each threat hunting or incident response case opened in the platform may be loaded with one or more playbooks. Individual threat behavior analytics fire in the platform and are tied to specific playbooks, which aid analysts in response and investigation.
In addition to new analytics, our experienced Threat Operations Center team provides a new set of playbooks with each content pack release for the Dragos Platform. So, what exactly does a playbook in the Dragos Platform contain? At the most basic level, it contains a step-by-step list of directions.
To account for varying experience levels, each step may be expanded to show more detailed help in performing the directed action. The end goal is to provide as much concise guidance and education to any analyst using our platform as possible.
List of definitions Roles Roles defined in this collection are listed below. List of packages are listed in 'packages' in site config. Note, openssh and ansible are required to be installed by preseeded installation media. Will not touch local output lines, so comment them out by hand if in need. Definitions and requirements on modification To write roles and playbooks, following points are required to be considered.
System configurations after installation using built ISO images are assumed to be done by Ansible, preseed configurations are to install bare OS with Ansible to run. Releases No releases published.

This opportunity to detect anomalies much quicker and more accurately makes NSM an effective defense strategy for neutralizing adversaries in ICS. Performing regular vulnerability scans on critical business services is a good practise.
Automating them and having the results delivered to an IT team's inbox on a regular basis is a great practise. I've seen this work very well in IT quickly followed up with remediation plans. Vulnerability scanning in an ICS network can have unpredictable and undesirable effects. For example, scanning older PLCs with "xmas tree scans" could exhaust CPU and memory resources rendering unresponsive controllers. But tipping over PLCs is becoming less common.
In recent years vendors have been building more security into ICS devices with the introduction of new models and through upgraded firmware.
No-cost added protection could be just a well planned firmware upgrade away, but realize general active scanning in ICS environments can impact operations.
While there are some scanning products available for safe use in ICS it's highly recommended they are tested in development first and supported by all stakeholders, including safety departments and change management.
Alternative less invasive methods of vulnerability assessments can be performed by reviewing asset inventories, configuration files and firmware versions against threat intelligence and vulnerability advisories. With careful planning and a phased approach vulnerability assessment can happen effectively in ICS.
Patching operating systems and software is an effective security practice that's been common place in business networks for decades. For ICS there are special circumstances where patching may not be feasible or possible within a normally accepted timeframe. This could be the case with legacy equipment or critical infrastructure systems. However, patching has become more acceptable in ICS environments in recent years given the threat landscape, availability of patches, patch testing by ICS vendors, and standards such as NERC North American Electric Reliability Corporation for the electrical utility sector.
Patching is not a "nice to have", it's a requirement with strict criteria from when patches are identified, reviewed and applied. Compensating controls then could be used to reduce risk in some cases. Many ICS vendors go to lengths to verify their software on common operating systems not long after patch notifications. This process continues to improve across multiple sectors so patching is becoming more of a positive and achievable part of preventative maintenance that facilities can benefit.
Patch vulnerabilities that are applicable in your environment in a phased and controlled approach for success. Add additional monitoring or compensating controls where patching is not feasible or possible within an normally accepted timeframe.
Encrypting traffic between remote sites over inherently insecure channels can protect both IT and ICS networks, and is a general best practice. However, confidentiality inside an ICS is less of a requirement compared to inside business networks.
Internal ICS network encryption can provide unintended challenges. Attention to end point processing power, network latency and bandwidth consumption, especially in facilities with legacy equipment will be needed. Also realize if encryption is used internally even though network flow data like traffic patterns and 5 tuple data is still available, critical defense initiatives such as NSM will be degraded.
