Abstract

An alternative methodology using new preventative technology to manage cybersecurity exposure on deepwater drilling rig assets is presented. For the past two years Shell's Deepwater Wells business has been evaluating typical cyber defence approaches and undertaken cybersecurity risk assessments and penetration tests. These activities have demonstrated the challenges attaining cybersecure drilling rig environments. Whilst cyberattacks increase in frequency, adaptability, and become cheaper to launch, regulatory and liability insurance requirements are also evolving. To achieve the goal of cyber-resilience, a major Operator has collaborated with a cybersecurity firm to trial technology for rapidly and reliably protecting deepwater rigs. The paper presents aspects of the numerous challenges faced and offers a different approach using new technology applied to both supplement and accelerate the attainment of a cyber-resilient environment onboard deepwater drilling rigs. It shares the deep dive lessons learnt leading to a more comprehensive understanding of how to protect drilling rigs and their safety critical control systems. Aside from addressing technical attributes using risk vs. maturity based methods, the approach also caters to business demands of short term rig contracts, managing multi-vendor legacy systems and satisfying increasing digitalisation/remote access needs with associated reductions in overall cybersecurity CAPEX spend.
海上深水钻井平台的网络防御
提出了一种替代方法,使用新的预防性技术来管理深水钻井平台资产的网络安全风险。在过去两年中,壳牌深水井业务一直在评估典型的网络防御方法,并进行网络安全风险评估和渗透测试。这些活动表明了实现网络安全钻井环境的挑战。虽然网络攻击的频率、适应性和发动成本都在增加,但监管和责任保险要求也在不断变化。为了实现网络弹性的目标,一家大型作业者与一家网络安全公司合作,对快速可靠地保护深水钻井平台的技术进行了试验。本文介绍了所面临的众多挑战的各个方面,并提供了一种不同的方法,使用新技术来补充和加速深水钻井平台上网络弹性环境的实现。它分享了深度潜水的经验教训,从而更全面地了解如何保护钻井平台及其安全关键控制系统。除了使用基于风险与成熟度的方法解决技术属性问题外,该方法还满足了短期钻机合同的业务需求,管理多供应商遗留系统,满足日益增长的数字化/远程访问需求,同时降低了整体网络安全资本支出。
