Applying Cybersecurity Best Practices
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?
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 vulnerabilities||Bad configurations (NTP/DNS/DHCP, etc.)|
|Cleartext or weak passwords||Corrupted OT packets|
|Device state change ||IP conflicts|
|New connections to the enterprise network||New connections to the Internet|
|New communications||New nodes|
|Policy violations||New remote access|
|Open ports on assets||Non-responsive asset|
|Unauthorized cross level communication||Unencrypted 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.
