datatofuA firewall is not enough. The major breach we analyzed was no due to a bad network but a broken philosophy. The lack of network segmentation allowed a single vulnerability to cascade into a devastating systemic failure. Learn how a smarter data architecture could have prevented it.<a href="https://mastodon.social/tags/DataArchitecture" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DataArchitecture</a> <a href="https://mastodon.social/tags/NetworkSegmentation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NetworkSegmentation</a> <a href="https://mastodon.social/tags/SiloedSystems" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SiloedSystems</a> <a href="https://mastodon.social/tags/DataGovernance" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DataGovernance</a> <a href="https://mastodon.social/tags/DataSecurity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DataSecurity</a> <a href="https://mastodon.social/tags/InfoSec" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#InfoSec</a> <a href="https://mastodon.social/tags/Cybersecurity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Cybersecurity</a> <a href="https://mastodon.social/tags/BusinessStrategy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BusinessStrategy</a> <a href="https://mastodon.social/tags/ShaolinDataScience" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ShaolinDataScience</a>

Claroty💡 On Nexus, Jim Miller, Director of OT Cybersecurity for Magna International explains how distributed <a href="https://infosec.exchange/tags/OT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OT</a> factory environments manage <a href="https://infosec.exchange/tags/cybersecurity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cybersecurity</a> from cultural issues to the need for proper <a href="https://infosec.exchange/tags/NetworkSegmentation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NetworkSegmentation</a>, and how to tune <a href="https://infosec.exchange/tags/firewall" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#firewall</a> rules to automate reviews. Miller explains how his team started with basic security configurations that should be in place, how risk scores are calculated for network segments against a safe baseline, and how those scores illuminate risk and improve protection versus just improving firewall rules.

Pen Test PartnersAre ships today more vulnerable to cyber attacks due to increased connectivity to their systems?🚢 In our latest blog post, Andrew Tierney explains the potential risks associated with systems such as the Power Management System (PMS)⚡ and Integrated Alarm and Monitoring System (IAMCS), which are responsible for controlling the power generation and other machinery onboard. ⚠️ The consequences if these are hacked? Blackouts, increased crew workload, and potential loss of control during manoeuvres - especially risky in busy waterways. While hackers taking full remote control of a vessel is unlikely, disruptions to these systems are a genuine concern due to rising automation and inadequate network segmentation. 🛳️ Dynamic positioning vessels and cruise ships have even more complex, integrated systems. Inadequate network isolation among systems like dynamic positioning, safety management systems, and voyage data recorders can allow a hacker to impact multiple systems at once, making recovery far more challenging. 👉 Find out Andrew Tierney's full thoughts and breakdown on how cyber attacks could disrupt modern ship operations in our latest blog: <a href="https://www.pentestpartners.com/security-blog/cyber-threats-to-shipping-explained/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.pentestpartners.com/security-blog/cyber-threats-to-shipping-explained/</a><a href="https://infosec.exchange/tags/MaritimeCybersecurity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MaritimeCybersecurity</a> <a href="https://infosec.exchange/tags/PMS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PMS</a> <a href="https://infosec.exchange/tags/IAMCS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IAMCS</a> <a href="https://infosec.exchange/tags/NetworkSegmentation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NetworkSegmentation</a> <a href="https://infosec.exchange/tags/OperationalRisk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OperationalRisk</a> <a href="https://infosec.exchange/tags/CyberAwareness" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CyberAwareness</a> <a href="https://infosec.exchange/tags/CyberSecurity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CyberSecurity</a> <a href="https://infosec.exchange/tags/ShipCyberSecurity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ShipCyberSecurity</a> <a href="https://infosec.exchange/tags/MaritimeSecurity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MaritimeSecurity</a>
