Defending industrial operations from cyberthreats ought to all the time be prime of thoughts.

You’ll be able to’t safe what you don’t learn about. You want full visibility into your industrial community and OT safety posture, so you will have the data you should cut back the assault floor, section the commercial community, and implement cybersecurity insurance policies. Cisco Cyber Vision provides you real-time, detailed visibility into your industrial belongings, their communication patterns, and utility flows. It embeds visibility capabilities into industrial community tools, so there’s no want for devoted safety home equipment or to construct out-of-band SPAN assortment networks.
2. Phase the community into smaller belief zones
Community segmentation is essential to securing your community and defending essential industrial processes. It’s additionally a requirement of the ISA/IEC62443 security standards. Utilizing devoted safety home equipment for zone segmentation requires you to deploy extra {hardware}, create and preserve firewall guidelines, and even change community wiring and IP addresses.

Cisco Identity Services Engine (ISE) works with community switches, routers, and wi-fi entry factors to limit communications as per the outlined zones. And it uses groups defined in Cyber Vision to permit/deny communications for every asset and drives collaboration between IT and OT groups.
Be a part of us for a webinar on October 31 for extra particulars on how to comply with the ISA/IEC62443 security standards.
3. Safe distant entry to OT belongings
Distant entry is essential for operations groups, distributors, and contractors to configure, preserve, and troubleshoot OT belongings with out time-consuming and expensive visits. Nevertheless, many current distant entry options create safety backdoors or include many tradeoffs Cisco Secure Equipment Access (SEA) is fixing the challenges of deploying safe distant entry to operational belongings at scale and brings all the advantages of a zero belief community entry (ZTNA) resolution 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 be taught 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 Conference 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.

The convention attracts ICS stakeholders throughout a bunch of industries and quite a lot of OT, IT, authorities, distributors, and extra. Be sure to cease by the Cisco Sales space #18 to debate additional and meet the crew.
