Applying Cybersecurity Best Practices

The Challenge

Improving Your Cyber Resilience by Proactively Containing Risks

Operational risk comes from multiple sources including people, processes and technology. According to the Verizon 2019 Data Breach Investigations Report, intentional attacks on manufacturing by outsiders accounted for 70% of all breaches reported.1

But external threats aren’t the only risks that keep company leaders awake at night – accidental and unintentional cyber incidents caused by employees or suppliers can impact productivity as well. Examples include device configuration errors, open ports, the use of weak passwords, and forgetting to remove a contractor’s access after they’ve left the organization.

Given the significant risk to operations, it’s not surprising that OT leaders want to up their game by adopting cyber security best practices. But how do you implement a cyber security framework, and take cyber resiliency to the next level?

The Solution

Proactive Cyber Risk Detection and Effective Incident Response

Nozomi Networks makes it easy for you to understand and adopt cyber security best practices such as those outlined by the NIST Cybersecurity Framework for Manufacturing, IEC 62443 and ISO 27000.

For example, NIST outlines five security framework functions – identify, protect, detect, respond and recover, that should be incorporated into your operational processes to address cyber risk. Identification includes asset management and risk assessment, while detection includes continuous monitoring and insight into anomalies and events, among other functions.

The Nozomi Networks solution makes it easy to apply best practices around multiple NIST framework functions. As examples, it automates the creation of an asset inventory, continuously monitors your network and ICS, and rapidly identifies vulnerabilities. It also proactively identifies cyber risks that threaten the security of your industrial control systems, including:

Assets with vulnerabilitiesBad configurations (NTP/DNS/DHCP, etc.)
Cleartext or weak passwordsCorrupted OT packets
Device state change
IP conflicts
New connections to the enterprise networkNew connections to the Internet
New communicationsNew nodes
Policy violationsNew remote access
Open ports on assetsNon-responsive asset
Unauthorized cross level communicationUnencrypted communications (Telnet)

Adopting a trusted security framework such as NIST, and using the advanced monitoring and risk identification capabilities of Guardian™ will help you embed security into your organizational processes and improve your cyber resiliency.

Superior Operational Visibility and Advanced ICS Threat Detection

Guardian helps you apply cyber security best practices to proactively identify and contain operational risks.

More Operational Visibility & Cybersecurity Challenges

Effectively Monitoring My ICS Network

To stay on top of what’s happening, I need real-time visibility into my assets, connections, communications, protocols and more.

Keeping My Production Lines Running

Unplanned downtime can cost millions in lost production capacity, and create inventory headaches that hit my bottom line.

Integrating Our IT/OT Security Efforts

To close security gaps and protect my manufacturing processes against disruption, I need to leverage the expertise of IT.
