Home-Automation which it automates as connection home by network gives human beings to many conveniences but there is problem must solve. Rightly it is an illegal infiltration against the information transmission and a joint ownership of information home appliance machinery and tools. Especially design of Home Automation is necessary for Information Security because the vulnerability is exposed when it is connecting on the mobile communication terminal and the home appliance machinery and tools. In this research, we're going to help to function and efficiency improvement of Korean Home-Automation by Security Design and proposal for a research and development of Korean Home-Automation.

It becomes common to use computers to control electronic devices and security facilities in newly constructed buildings and house. There are many home application devices in the market which can be controlled by computers. But they are expensive and managed by specialized companies. This paper is focused on personal computers which are available in most homes and can be used to control home electronic appliances and home security facilities. We implemented a home automation server based on Linux. The standard parallel port of personal computer is used to connect sensors and actuators. Therefore, the cost of the server is very low. Moreover, the server is connected to Internet and anywhere we can control and monitor the home security facilities and home automation systems.

As the youngest branch of information hiding, network covert timing channels conceal the existence of secret messages by manipulating the timing information of the overt traffic. The popular model-based framework for constructing covert timing channels always utilizes cumulative distribution function (CDF) of the inter-packet delays (IPDs) to modulate secret messages, whereas discards high-order statistics of the IPDs completely. The consequence is the vulnerability to high-order statistical tests, e.g., entropy test. In this study, a rich security model of covert timing channels is established based on IPD chains, which can be used to measure the distortion of multi-order timing statistics of a covert timing channel. To achieve rich security, we propose two types of covert timing channels based on nested lattices. The CDF of the IPDs is used to construct dot-lattice and interval-lattice for quantization, which can ensure the cell density of the lattice consistent with the joint distribution of the IPDs. Furthermore, compensative quantization and guard band strategy are employed to eliminate the regularity and enhance the robustness, respectively. Experimental results on real traffic show that the proposed schemes are rich-secure, and robust to channel interference, whereas some state-of-the-art covert timing channels cannot evade detection under the rich security model.

국내 외에서 공장자동화에 대한 관심과 개발이 활발하게 시도되고 있다. 특히, 중소기업들은 공장자동화를 통한 생산성 향상을 위해서 노력하고 있다. 최근에는 독일의 인더스트리4.0 표준을 준수하고자 하는 노력이 전 세계적으로 시도되고 있다. 하지만 이것은 높은 개발 비용과 설비 비용 때문에 실질적인 투자나 개발은 이루어지지 않고 있다. 그러므로 우리는 공장자동화시스템의 생산성을 높이기 위해서 SEB를 설계 및 제작하고자 시도하였다. SEB는 RFID와 WiFi 네트워크를 연동해서 기존 공장자동화 시스템보다 통신 범위를 넓히고, 전송 속도도 빠르게 개선하였다. 그리고 기존에 공장자동화 시스템에서 취약점인 보안 문제를 해결할 수 있도록 사용자 인증에 대한 부분을 추가로 해결할 수 있다.

Detecting intrusion attacks accurately and rapidly in wireless networks is one of the most challenging security problems. Intrusion attacks of various types can be detected by the change in traffic flow that they induce. Wireless industrial networks based on the wireless networks for industrial automation-process automation (WIA-PA) standard use a superframe to schedule network communications. We propose an intrusion detection system for WIA-PA networks. After modeling and analyzing traffic flow data by time-sequence techniques, we propose a data traffic prediction model based on autoregressive moving average (ARMA) using the time series data. The model can quickly and precisely predict network traffic. We initialized the model with data traffic measurements taken by a 16-channel analyzer. Test results show that our scheme can effectively detect intrusion attacks, improve the overall network performance, and prolong the network lifetime.

Successful implementations of DevOps practices significantly improvise software efficiency, collaboration and security. Most of the organizations are adopting DevOps for faster and quality software delivery. DevOps brings development and operation teams together to overcome all kind of communication gaps responsible for software failures. It relies on different sets of alternative tools to automate the tasks of continuous integration, testing, delivery, deployment and monitoring. Although DevOps is followed for being very reliable and responsible environment for quality software delivery yet it lacks many quantifiable aspects to prove it on the top of other traditional and agile development methods. This research evaluates quantitative performance of DevOps and traditional/ agile development methods based on software metrics. This research includes three sample projects or code repositories to quantify the results and for DevOps integrated selective tool chain; current research considers our earlier proposed and implemented DevOps hybrid model of integrated automation tools. For result discussion and validation, tabular and graphical comparisons have also been included to retrieve best performer model. This comparative and evaluative research will be of much advantage to our young researchers/ students to get well versed with automotive environment of DevOps, latest emerging buzzword of development industries.
