Cybersecurity teams have no shortage of threat data: New vulnerabilities are disclosed, malware is discovered, attack campaigns are analyzed, and manufacturers, CERTs, and security agencies continuously publish indicators of compromise (IoCs), security advisories, and other technical information. For operators of critical infrastructure, however, collecting this information is not even the most challenging part. Security teams still need to determine whether a threat is relevant to their environment, which assets may be affected, and what the observed activity actually means in the context of an operational network. In the energy sector, that requires knowledge extending beyond enterprise security and into the protocols, equipment, and processes that keep power systems operating. A suspicious packet in an office network is one thing. Understanding whether communication between an engineering workstation and a protection device using IEC 61850 represents expected maintenance activi...

OT incidents rarely start with "OT attacks." They start with ordinary enterprise weaknesses: shared credentials, remote access shortcuts, management systems that bridge zones too easily, and monitoring that stops short of operations.  When those weaknesses line up, an initial IT compromise becomes an OT event, and the deciding factor is no longer whether the activity is detected, but whether the environment can be contained and recovered without extended outage. What matters is that these failure patterns repeat across industries, which means they can be anticipated and solved - but only if recovery is treated as a security control, not an afterthought.

Throughout history, societies have protected their most valuable assets by building walls, fortresses, and moats. Whether it was a medieval castle or an ancient city-state, security meant keeping threats on the outside and creating barriers around the things that mattered most.  We took these principles with us as we moved into the digital age, designing network security with firewalls, access controls, and gated perimeters to protect digital assets. Firewalls and network devices became our virtual walls, defining trusted and untrusted zones, and keeping the "bad actors" at the gate. For years, this perimeter-based approach was the primary line of defense in the world of cybersecurity, establishing a digital fortress around systems and data. But just as history has shown us that walls and borders can be breached, so too has modern cybersecurity taught us that no perimeter is foolproof. As organizations increasingly connect their IT systems to the wider internet and integrate the...
