Enhancing IoT Security Using IPTABLES on Raspberry Pi: A Lightweight Firewall Approach with Real-time Monitoring and Notification System

Trisilp Jitnarwee — 2025-08-21

Currently, Internet of Things (IoT) devices are widely used in various fields. However, due to their resource constraints, such as low processing power, limited memory, and restricted energy supply, deploying traditional cybersecurity solutions, including Intrusion Detection Systems (IDS) and complex firewalls, is challenging. This research aims to develop an approach using IPTABLES Firewall on Raspberry Pi as a Lightweight Firewall to enhance the security of IoT devices. The focus is on protecting against four types of attacks: Port Scanning, Brute Force Attack, Denial of Service (DoS), and Man-in-the-Middle (MITM), along with a real-time alert system through email and Telegram. The system was tested on a Raspberry Pi, simulating attacks from Kali Linux, to evaluate its performance using metrics such as False Positive Rate (FPR), False Negative Rate (FNR), CPU Load, Memory Usage, and Network Latency. The test results showed that the system could effectively detect and prevent Port Scanning, Brute Force, and DoS attacks with low False Positive and False Negative rates. However, MITM attack prevention has certain limitations because IPTABLES operates at Layer 3-4 of the OSI Model. In conclusion, the developed Lightweight Firewall system can enhance the security of IoT devices efficiently without significantly impacting system performance. This makes it a suitable solution for protecting resource-constrained IoT devices against cybersecurity threats.

The Right of Withdrawal for Consumers in General Insurance Contracts

Natnicha Promhom — 2025-08-21

Individuals in society are constantly exposed to various forms of uncertainty and risk in their daily lives. Insurance functions as an economic tool and a form of consumer behavior aimed at protecting individuals from potential financial consequences arising from such risks. Insurance policies, which serve as evidence of general insurance contracts, are typically unilaterally prepared by insurers based on their business expertise and presented in standard form, which does not afford consumers a realistic opportunity to bargain over the terms. One approach in consumer protection involves the inclusion of a cooling-off period, a designated timeframe after contract conclusion during which consumers may withdraw from the contract. This period offers consumers an opportunity to review and understand the product and contract terms, particularly in complex or pre-drafted agreements. This study examines the characteristics of general insurance contracts, legal concepts related to contracts and consumer protection, and legal measures concerning consumer protection in general insurance contracts in selected foreign jurisdictions and Thailand. It concludes that consumers should be granted the right to terminate general insurance contracts within such a period, and that this right should be clearly disclosed during the offering of the insurance policy. The study also identifies gaps in Thailand’s current legal measures that result in inadequate protection for consumers.

A total of 69 data sets were randomly selected by choosing one set out of every 40 entries. All data were processed using SPSS software for analysis and mathematical model construction. Hypothesis testing and multiple regression analysis were employed, specifically using the Stepwise Regression method, and model selection was based on the R-squared value. The research was conducted between September and October 2024.The variables in this study included demographic factors age and gender and environmental factors such as needs related to personal interests, educational needs, and basic needs (the four necessities of life). These needs were rated on a scale from 0 to 5, ranging from no interest to full interest. The findings revealed that 44.93% of the sample were male and 55.07% were female. The majority, or 84.06%, were aged 15 and above. Among demographic factors, only age had a statistically significant effect on students’ saving expenses, while gender did not influence any of the models. Regarding savings motivated by personal interests, a relatively high correlation was observed. The mathematical models produced from the analysis showed low accuracy when applied to savings for basic necessities. However, when analyzed within specific savings categories, the model accuracy improved significantly. Some models did not include all variables due to high multicollinearity among certain independent variables. A total of eight mathematical models were developed from the study.
