EV Charging – The Need For Cyber Risk Management
As the EV charging infrastructure expands around the world, it has increasingly become a target for hackers and cybercriminals seeking to exploit vulnerabilities in these critical systems. Cyber attacks on EV charging networks can compromise the safety and reliability of charging stations, crossing the domain from digital damage to physical catastrophes.
The latest vulnerabilities discovered on Autel, ABB, and ChargePoint Home AC chargers highlighted the need for Charge Point Operators (CPOs) to implement robust risk and vulnerability management strategies. CPOs need to enhance the resiliency of their EV charging infrastructure and protect it against cyber-attacks.
In this blog, we outline the cyber risks that CPOs need to be aware of and guide them through the essential steps to implement an effective risk management strategy.
The Potential Damage of Cyber Attacks on EV Charging Networks
Understanding the potential damage, risks, and vulnerabilities that exist in these networks is the first step in securing our EV charging infrastructure. It is also the first step in the implementation of the security standards and regulations that CPOs and owners will have to comply with, such as the EU’s NIS2 regulation and the NIST Cybersecurity Framework Profile for XFC. Let’s review the major risks cyber attacks pose on EV Charging Networks:
1. Operational Disruptions
By targeting the charging infrastructure and components, such as charging stations, network equipment, smart meters, and energy storage solutions, attackers can cause large-scale Denial of Charge, outages, or malfunctions, that can lead to local-grid destabilization or even blackouts, affecting not only the EV charging hubs but also nearby areas.
2. Financial and Reputational Damage
The impact on Charge Point Operators (CPOs) and owners extends beyond operations, as such attacks could lead to loss of revenue due to prolonged downtime, fines due to non-compliance with data protection regulations, and long-term reputational damage, which could harm customer trust.
3. Unauthorized Network Access
A breach in the charging network can expose personal information, such as customer data, charging patterns, and payment details, which could then be used for identity theft and fraud. Targeting the charging network can also be the first step of a multi-layered attack against the CPO or owner, and further the cyberattack into the organization’s network.
Top Risk Management Strategies CPOs Should Implement
CPOs must develop comprehensive risk and vulnerability management plans to safeguard their charging network operations. A strong cybersecurity risk management strategy starts with identifying, assessing, and mitigating potential threats that could compromise the operations, integrity, and continuity of the charging infrastructure. Below are key strategies that CPOs should implement:
1. Maintain Full Visibility Into All Assets Across The Charging Infrastructure
You can’t protect what you can’t see. The first step in handling the cyber risks is by gaining complete visibility into all assets and components within your EV charging network. This includes not just the charging stations but also the connected network equipment, IoT devices, smart meters, energy storage units, sensors, and grid-edge devices that are part of the charging operations.
By identifying and mapping every device on your network, including its entire configuration status, you can better understand where potential vulnerabilities lie and prioritize their mitigation accordingly. Network monitoring tools and asset management solutions can provide real-time insights into device status, firmware versions, Software Bill of Materials (SBOM), and configuration changes.
Full visibility allows you to quickly detect unauthorized devices, misconfigurations, or outdated software, helping you maintain a continuously secure and resilient infrastructure.
2. Monitor For Known Vulnerabilities (CVEs) and Security Gaps
Staying ahead of potential threats requires continuous monitoring of your EV charging infrastructure for known vulnerabilities and security gaps. Regularly tracking vendors’ security advisories and patches is crucial, as outdated firmware and unpatched software can leave your network exposed. Moreover, common security gaps, such as network misconfigurations—like open ports or weak segmentation—and the use of default credentials on critical systems, are frequently targeted by attackers.
Implementing real-time monitoring tools that detect these vulnerabilities and automatically alert you on any suspicious activity, misconfigurations, or outdated and vulnerable firmware versions enables you to address threats proactively before they can be exploited. This approach ensures that your EV charging network remains up-to-date, properly configured, and secured against potential attacks.
3. Prioritize Vulnerabilities Based On Risk and Exploitation Likelihood
To effectively manage cybersecurity risks in EV charging sites, it’s crucial to prioritize vulnerabilities and security gaps according to their risk level and likelihood of exploitation. Not all vulnerabilities pose the same threat level, so assessing the potential impact and exploitability of each issue could help you optimize and prioritize resources on the most critical risks.
For example, a vulnerability in the firmware of a widely used EV charger that could lead to unauthorized access or data breaches should be addressed with higher urgency than a less severe issue. Similarly, gaps in network security, such as misconfigured routers or exposed administrative interfaces, might present significant risks if they are easily exploitable by attackers.
By employing risk assessment frameworks and tools that evaluate the potential impact and likelihood of exploitation for each vulnerability in the EV charging network, you can focus your remediation efforts more effectively. This strategic approach ensures that the most dangerous and exploitable issues are addressed promptly, improving the overall security and resilience of your EV charging network.
Summary
Deploying risk and vulnerability management strategies is an essential component in safeguarding the EV charging infrastructure from cyber threats. By proactively identifying and addressing vulnerabilities, operators can ensure the security, reliability, and trustworthiness of charging stations, protecting both users and the broader power grid from potential attacks, unauthorized access, data breaches, and service disruptions.
