Defending industrial operations from cyberthreats ought to at all times be high of thoughts.

Signal as much as watch the replay: Defending industrial networks from cyber threats: The place do I begin?
Within the webinar, Kam recommends a stepped strategy in direction of a mature ICS/OT safety technique, implementing the next greatest practices:
1. See every part in your industrial community
You may’t safe what you don’t learn about. You want full visibility into your industrial community and OT safety posture, so you could have the data you have to cut back the assault floor, section the economic community, and implement cybersecurity insurance policies. Cisco Cyber Imaginative and prescient offers you real-time, detailed visibility into your industrial property, their communication patterns, and utility flows.

2. Phase the community into smaller belief zones
Community segmentation is essential to securing your community and defending crucial industrial processes. It’s additionally a requirement of the ISA/IEC62443 safety requirements. Utilizing devoted safety home equipment for zone segmentation requires you to deploy further {hardware}, create and preserve firewall guidelines, and even change community wiring and IP addresses.

Cisco Identification Companies Engine (ISE) works with community switches, routers, and wi-fi entry factors to limit communications as per the outlined zones. And it makes use of teams outlined in Cyber Imaginative and prescient to permit/deny communications for every asset and drives collaboration between IT and OT groups.
Be part of us for a webinar on October 31 for extra particulars on how one can adjust to the ISA/IEC62443 safety requirements.
3. Safe distant entry to OT property
Distant entry is essential for operations groups, distributors, and contractors to configure, preserve, and troubleshoot OT property with out time-consuming and expensive visits. Nevertheless, many current distant entry options create safety backdoors or include many tradeoffs Cisco Safe Tools Entry (SEA) is fixing the challenges of deploying safe distant entry to operational property at scale and brings all the advantages of a zero belief community entry (ZTNA) answer to industrial operations. There isn’t a devoted {hardware} to put in and handle and no advanced firewall guidelines to configure and preserve.
If you wish to study extra, be a part of us for a session on ZTNA on October 25 for IIoT World Cybersecurity Day.
For extra particulars on how one can get began along with your industrial safety journey, watch Kam’s webinar replay or come to the SecurityWeek ICS Cybersecurity Convention in Atlanta subsequent week, the place Anastasia Mills and Kam Chumley-Soltani can be presenting a breakout session on Wednesday, October 25 at 10:25 am PST.
