Talking Points

Recent interactions between the hosts and their guests.

Sub Cable Security | Ferris Adi
Q: What is the role of governance and executive leadership in cybersecurity for submarine cables?
Security must be treated as a business risk and an enabling factor for the enterprise. The board and senior management should drive resilience, fund security properly, and ensure security is embedded in strategy and branding, not just IT.
Sub Cable Security | Ferris Adi
Q: How should organizations prepare for breaches and not just focus on prevention?
Prepare with a detailed incident response plan, clearly defined roles, regular tabletop exercises, tested backups, rapid detection, transparent communication, and a governance-focused approach that involves the entire executive team.
Sub Cable Security | Ferris Adi
Q: What are the key threats that submarine cables face and how do you mitigate them?
Threats exist in physical, logical, and geopolitical domains. Mitigation requires defense in depth, physical isolation, robust access controls, updated firmware, multi-factor authentication, encryption, and strong vendor management to reduce risk across the entire supply chain.
Submarine Cable Routing | James Porter
Q: How do you actually go about doing this, and what software and data do you rely on to understand the relationships between cables?
The process starts with a desktop study, site visits, and then loading data into a GIS-based tool (MacEye) along with internal and public databases. The route is iteratively adjusted to satisfy depth, seabed type, and protection requirements, while also accounting for existing cables and third-party repeats, supported by bathymetric and geophysical survey data from subcontractors.
Submarine Cable Routing | James Porter
Q: Could you just tell us briefly about what the paper was about and especially why you think this paper was necessary to present at Suboptic this year?
James explains that the paper focused on submarine cable routing with an emphasis on the interplay of geopolitics, seabed features, and existing infrastructure, arguing that robust mapping and standardization help operators design compliant, installable routes even in congested areas. The presentation at Suboptic showcased practical mapping approaches and the need for clear data to inform routing decisions.
