This research aims to study the Mirai Botnet working process which made high bandwidth impacted to Internet system. From 90000 clients of Deutsche Telekom cannot access to Internet that overall bandwidth growth nearly 1 TB per second in the history DDoS attacking behavior. As Mirai exaggerated attacking to ISPs and may be involved UniNet as a big umbrella which RMUTP network interconnected as well. The author would like to study in depth to several weak points of the end devices or IoT on Internet. In the Mirai code used the IoT devices such as the Internet cameras the CPUs based on ARM ARM7 Motorola 6800 SPC PowerPC X86 and SuperH (SH4). As the results of valuable attacking code studied based-on IPV4 attack without IPV6. The source code has more than 5500 lines with 16 files and 138 functions included 62 set of user accounts and passwords. Usage the 9 flooding techniques for port attacking via 22 23 and 80 with the IP scanning exceptions for DoD IANA GE and HP IP addresses. The Internet camera devices have to disable 22 23 and 80 ports or doing suitable usability techniques to manage for several flooding protection from system harmfully.

The purpose of this research is to study the effect of a safety system provided for wall tile external building activity on productivity. The safety system composed of (1) stable scaffolding system (2) providing clean and not slip walkways on the scaffold (3) installation of handrails not less than 0.90 meters in height along sides of the scaffold (4) installing safety nets around outside perimeters of the scaffolding (5) indicating working area (6) installing stairs (7) providing protection for people who works below (8) providing tools and equipments for transporting material which are safe and ready for using and (9) providing personal protective equipment for workers. Cost of the safety system is 79318 baht for a wall tile area of 385 m2 or approximately 206 baht/m2. Productivity rates for prior and after the used of safety system are 1.91 and 1.85 m2/person/day respectively. The productivity declines for approximately 3 %. In addition our study found an impact of work is a height of Building the wall tile external productivity could decrease for 6 %.

This study The objective is to research and evaluate the security of wireless networks Rajamangala University of Technology Phra Nakhon. To enhance the performance of the security of wireless networks. This research is a research and evaluation. In order to improve the security of wireless networks. The process of developing the procedures for the security of wireless networks. To improve security. It is a tool used in the evaluation is Kali Linux operating system. The findings The performance evaluation of such networks. Can be proved with the security of wireless networks. The study was done to evaluate the security of wireless networks. Found that satisfaction with the program was good

The objective of this qualitative study was to develop and determine security measures for private organizations. Documentary analysis and focus group technique were used as a method for gathering data. Eight participants who had experiences in security management were participated in a focus group. Data from two sources were gathered and integrated for data analysis. The results of data analysis led to the development of security measures factors. Findings indicated that there were five factors of security measures that needed to be implemented and carried out in private organizations including building awareness of technology development in security; integration of architectural security components; developing security systems; human resource management which encompasses security personnel and sharing knowledge; and determining appropriate security procedures that relate to nature and physical of organizations.

The purpose of this research is to study the effect of a safety system provided for column reinforcement activity on productivity by studying a construction of buildings in Bangkok. The safety system composed of (1) stable scaffolding system (2) providing clean and not slip walkways on the scaffold (3) installation of handrails not less than 0.90 meters in height (4) installing stairs and (5) providing personal protective equipment for workers. Cost of the safety system is 40030 baht for a column reinforcement area of 40 numbers. Productivity rates for prior and after the used of safety system are 11.06 and 8.80 kg./person/hr. respectively. The productivity declines for approximately 20.43 % the working time for column reinforcement could take longer for 13.18 % and labor cost could increase for 13.32 %.
