A 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.

Nice article! Can‘t agree more on all of them amd seen many of them in the wild:

📄 Default configurations of software and applications

⛔️ Improper separation of user/administrator privilege

🔎 Insufficient internal network monitoring

⚠️ Lack of network segmentation

🔄 Poor patch management

🔀 Bypass of system access controls

📱 Weak or misconfigured MFA methods

🎣 Lack of phishing-resistant MFA

🚫 Insufficient access control lists on network shares and services

🧼 Poor credential hygiene

👨🏼‍💻 Unrestricted Code Execution

💡 On Nexus, Jim Miller, Director of OT Cybersecurity for Magna International explains how distributed #OT factory environments manage #cybersecurity from cultural issues to the need for proper #NetworkSegmentation, and how to tune #firewall 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.

Are 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.

Network segmentation is the second area to address in zero trust planning and implementation. With segmentation you’re enhancing security by dividing networks into isolated zones with strict access controls.
 
Based on professional observations from numerous successful intrusions, network segmentation is one of the most common zero trust concepts not implemented. This is often due to the cost, time, and the staff necessary to design, implement and secure legacy network infrastructure when those legacy networks are not perceived as “broken” by the end-users or leadership.   This is where the adage, “If it’s not broke, don’t fix it” is most apparent and a difficult, but necessary area to explain to corporate stakeholders.

To properly conduct network segmentation, you should consider the following:

1.      Threat Containment: Isolating segments limits the impact of breaches, aligning with zero trust's principle of minimal trust.
2.      Granular Access Control: Enforce stringent access policies, verifying users and devices continuously regardless of location.
3.      Layered Defense: Combine segmentation with other tools for robust security layers against cyber threats.
4.      Adaptive Security: Adjust controls dynamically based on threat intel and user behavior, ensuring agility against evolving threats.
5.      Compliance Assurance: Facilitate compliance by segregating sensitive data, reducing audit scope and regulatory risks.
6.      Implement network segmentation to fortify your security posture and embrace zero trust principles effectively.

Zero trust and network segmentation aren’t one and done matters. They require constant reevaluation and change, this process of continuous evaluation, although tedious, always works in the favor of the defender.

One fundamental strategy that stands out as a powerful defense mechanism against intrusions is network segmentation. This practice involves dividing a network into smaller, isolated segments, each with its unique access controls and security measures.

Architects and admins should ask the five "W's" when designing a network.

-Who needs to access a specific network segment? Example: Firewall rules limiting network segments, or public/private VLAN communication paths.

-What systems or data do users need access to? Example: Does every department need to have access to the finance or HR subnet?

-When do specific resources need access? Example: 8a-5p, holidays, weekends, work hours, 24x7?

-Where can users access specific network resources? Example: Do VPN or ZTNA users have the same access as those users residing locally?

-Why does a server, endpoint or resource need to have unlimited access? Example: Do printers or IoT devices all need Internet access?

With well designed and implemented network segmentation businesses can significantly limit the potential damages caused by a computer intrusion.
