\u00a0<\/span><\/p>\nRemove Unnecessary User Accounts:<\/span><\/b> A test\/default account and password can be used by unauthorized parties to access systems if they are not removed from the technologies default configuration. Implementation accounts can be created, but they must be removed after the solution has been installed and not used for operation. It is important to identify and remove these accounts in the product and implementation documentation.<\/span>\u00a0<\/span><\/p>\nDisable Unused Functionality and Services:<\/span><\/b> In some solutions, all functionality and services are enabled by default. Disabling unused functionality and services reduces the attack surface and prevents possible attack vectors.<\/span>\u00a0<\/span><\/p>\nEnable Auditing of Security Events:<\/span><\/b> Continuously monitoring audit logs will assist in identifying breaches and attacks.<\/span>\u00a0<\/span><\/p>\nAdd Anti-Tampering and Anti-Vandalism Mechanisms: <\/span><\/b>Devices should be protected from unauthorized physical access, modification, vandalism, or theft.<\/span>\u00a0<\/span><\/p>\nOperations and Maintenance<\/span><\/h3>\nIt is essential to provide continuous support, tracking, and monitoring to a smart city once the solution has been implemented. The following requirements ensure safe operations:<\/span>\u00a0<\/span><\/p>\nMonitoring:<\/span><\/b> The organization is responsible for monitoring the stability of its services and monitoring any suspicious activity, abnormal behaviour, performance issues, or any other service-threatening events by regularly reviewing system audit logs and\/or other available tools.<\/span>\u00a0<\/span><\/p>\nPatching:<\/span><\/b> It is expected that organizations and vendors collaborate on deploying the latest security patches. Patches should be deployed in accordance with the company’s patch management policies, considering the urgency of the patches. In comparison to traditional enterprise IT systems, patching IoT devices presents challenges. It is frequently necessary to update the firmware of the device via secure updates, i.e., encrypted and signed.<\/span>\u00a0<\/span><\/p>\nRegular Assessment and Auditing: <\/span><\/b>Smart services should also be tested continuously to ensure compliance with standards and security policies (e.g., ensuring encryption is enabled, authentication is enabled, strong passwords are set, security settings are not altered, etc.). It is imperative to protect infrastructure to be prepared to respond to vulnerabilities and exploits every day.<\/span>\u00a0<\/span><\/p>\nProtection of Logging Environment:<\/span><\/b> The integrity and protection of evidence are crucial to investigating misbehaviour, tracking incidents, and determining legal liability. All logs need to be transmitted and stored safely. Data collection and routinely forwarding of data may not be possible on some ices, so logging should occur as close to the end<\/span> –<\/span>device as possible.<\/span>\u00a0<\/span><\/p>\nAccess Control: <\/span><\/b>To prevent unplanned changes, tampering, or downtime in smart cities, it is critical to monitor who, when, and how people have access to smart service systems.<\/span>\u00a0<\/span><\/p>\nCyber Threat Intelligence:<\/span><\/b> A threat intelligence system helps an organization identify regional and worldwide threats, such as new, trending, common, and regional attacks. By using such information, organizations can update their security posture and parameters to prevent attacks in advance. In many cases, attacks are replicated<\/span>,<\/span> and vulnerabilities are reused. In addition, cyber-threat intelligence<\/span>. <\/span>It could be used at a country level by the government to prevent certain traffic patterns and source locations from flowing through regional Internet gateways, thereby protecting all organizations within the country.<\/span>\u00a0<\/span><\/p>\nCompromise Reaction and Recovery:<\/span><\/b> If a smart city system is compromised, detailed procedure manuals and checklists should be created describing what needs to be done. The steps include revocation of certificates, erasure of keys, system isolation<\/span>,<\/span> and clean-up, as well as following up on the incident to understand how the system was compromised and develop plans to prevent it from occurring again in the future.<\/span>\u00a0<\/span><\/p>\nTechnology Disposal<\/span><\/h3>\nSmart city technologies are complex. Organizations plan for them, implement them, and then they need to dispose of them on a specific date. During the disposal process, multiple factors need to be considered. Organizations need to develop policies that ensure that technology is securely disposed of, keeping the following in mind:<\/span>\u00a0<\/span><\/p>\n\n- Technology should not be repurposed by the same organization or by third parties. It could expose sensitive design, client, password, or cryptographic information, posing a threat to production services.\u00a0<\/span>\u00a0<\/span><\/li>\n
- In order to ensure the safe, rapid disposal of critical data, it may be necessary to destroy the storage of data on the system<\/span>s<\/span>.<\/span>\u00a0<\/span><\/li>\n
- The replacement of a vendor is also important. While many organizations focus on disposing of data correctly, smart service systems could be used by vendor maintenance and support personnel to perform regular maintenance tasks. They could repurpose hardware or dispose of it without appropriate security measures if they replace hardware.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
Conclusion<\/span>\u00a0<\/span><\/h2>\nThe rise of smart cities is being powered by technology, which is digitally transforming necessary functions from public parking to public safety to traffic management and waste management. A new wave of digital transformation also brings new cyber risks that could fundamentally affect smart cities. Smart city developers (such as government entities and businesses) must be able to effectively monitor and manage their IoT infrastructure in order to reduce cyber risks.<\/span>
