Edge computing is quickly gaining popularity because it shifts processing and storage to the edge of the network, enabling low-latency, high-efficiency, real-time operations. Making the switch from a centralized data center to this creative alternative seems promising to a lot of people. It does, however, also present important cybersecurity risks or threats that must be handled.
5 Major Cybersecurity Risks of Edge Computing
Although edge computing has several advantages, there are various cybersecurity risks associated with its use. The following are the top five dangers connected to edge computing:
1. ) IoT-Specific Vulnerabilities
Due to their lack of built-in security measures, Internet-connected devices, or IoT devices, are frequently extremely susceptible to assaults like man-in-the-middle and botnets. IoT attacks exceeded 112 million in 2022 (compared to 32 million in 2018). Since most edge computing solutions rely on these devices, there is a serious cybersecurity risk associated with their weaknesses.
2. ) Overabundance of Logs
It can be quite difficult to manage security logs when there are hundreds or thousands of endpoints. The amount of daily alerts is already overwhelming the teams of over 50% of chief information security officers. This problem can be made worse by adding the duty of monitoring a decentralized edge structure, which raises the possibility of missing important threats and squandering resources on false positives.
3. ) Data Compromises
It is difficult to secure any IoT device in a decentralized system, in contrast to centralized data centers. Man-in-the-middle and ransomware attacks are more likely to target data that is gathered, kept, and exchanged at the edge. Sniffing attacks, for example, have the ability to intercept and take over unencrypted data in transit. Edge devices are especially vulnerable since they frequently lack the computing capability for strong encryption.
4. ) Expansive Attack Surface
By positioning devices near to the edge of the network, edge computing lowers latency and boosts bandwidth. On the other hand, this gives attackers multiple possible ports of entry into a dispersed assault surface. Every machine situated near the edge poses a risk and must be protected.
5. ) New Budget Limitations
The technical implementation of edge computing is challenging and necessitates large expenditures in IT and telecom infrastructure. Budgets may be strained by the continuous expenses of manpower and device maintenance, even with large upfront investments. This reduces the amount of money available for military deployment or failure recovery.
Mitigation Strategies for Edge Computing Risks
Despite these dangers, careful preparation and financial commitment might lessen the impact of edge computing-related cybersecurity concerns. Here are a few successful tactics:
1. ) Utilize Authentication Controls
Unauthorized access can be avoided by putting authentication measures like biometrics, one-time passcodes, and multi-factor authentication (MFA) into place. Even if you have faith in your team, it is imperative to utilize these solutions because human error is responsible for 27% of data breaches.
2. ) Cybersecurity Risks Automate Log Monitoring with AI
Automating log monitoring with artificial intelligence (AI) can help identify indicators of compromise (IOCs) before they become full-blown threats. AI can outperform humans in detecting suspicious activities, such as unusual network behavior and failed login attempts. Studies show AI algorithms can achieve a 99.6% recall rate for high-priority notifications and a very low false positive rate.
3. ) Authenticate Devices and Users
By requiring edge device authentication, all endpoints are validated prior to network access. This lowers the possibility of invasion by preventing illegal devices from connecting. It also facilitates the identification and tracking of risks by linking anomalous activity to particular machines.
4. ) Encrypt Network Traffic
While encryption is crucial for cybersecurity, it is resource-intensive and may not be feasible for widespread deployment in edge computing. By classifying data to prioritize encryption for critical endpoints and information, you can enhance security without overwhelming the system. Encryption should be applied both at rest and in transit using strong encryption keys.
5. ) Deploy an Intrusion Detection AI
A specially designed intrusion detection system is necessary because of the energy, processing, and memory constraints of edge computing. It is possible to customize deep learning algorithms to identify and categorize attack patterns that were previously unknown. These algorithms are perfect for edge situations because they can handle several endpoints, process massive volumes of data, and adjust on their own over time.
