With the rapid development of IT technology, integration with existing industries has led to an increase in smart manufacturing that simplifies processes and increases productivity based on 4th industrial revolution technology. Security threats are also increasing and there are. In the case of supply chain attacks, it is difficult to detect them in advance and the scale of the damage is extremely large, so they have emerged as next-generation security threats, and research into detection technology is necessary. Therefore, in this paper, we collect, store, analyze, and visualize logs in multiple environments in real time using ELK Stack and Sysmon, which are open source-based analysis solutions, to derive information such as abnormal behavior related to supply chain attacks, and efficiently We try to provide an effective detection method.

SQL Injection attacks are one of the older attack techniques and are the dominant type of hacking attempts against web services. There have been many attempts to hack SQL injection attacks by exposing data or obtaining privileges. In this paper, we implement a log analysis system that can respond to SQL injection attacks in real time using the open source ELK Stack. did. By providing a visualization of SQL injection attack log data through the implemented system, it is expected that users will be able to easily grasp the degree of attack risk and quickly prepare for attacks.

With the development of IT technology, cybercrime is becoming sophisticated and intelligent. In particular, in the case of BackDoor, which is used in the APT attack (intelligent continuous attack), it is very important to detect malicious behavior and respond to infringement because it is often unaware that it has been damaged by an attacker. This paper aims to build an EDR platform that can monitor, analyze, and respond to malicious behavior in real time by collecting, storing, analyzing, and visualizing logs in an endpoint environment in real time using open source-based analysis solutions ELK Stack and Sysmon.

Data on the crude protein requirements of elk doe are nonexistent and the data are essential for their management in Korea. Therefore, this study was conducted to evaluate the crude protein requirement for maintenance of elk doe. Three female elk deer were used in 3 × 3 Latin square design with three diets containing three levels of crude protein (CP) that contained low crude protein (approximately 12%), medium crude protein (15%), and high crude protein (18%). Each three elk doe trials included a 14-day preliminary period and a 5-day collection period. Crude protein intake was 4.83, 6.26, and 9.00 g/d for 12%, 15%, and 18% of CP level, respectively. Crude protein balances were 1.04, 1.41, and 4.14 for 12%, 15%, and 18% of CP level, respectively. The maintenance requirement for CP from the regression equation between CP intake and CP balance were 3.70 g/BW^0.75.

The study was conducted to determine the effects of hormone injection on casting day of antler, velvet antler yield, and blood hormone concentration in elk deer and Sika deer. The study revealed that the casting day of Elk and Sika deer at medroxy progesterone acetate(MPA) injection averaged 21 days after MPA injection, which was earlier 38 and 24 days, respectively, compared control(P<0.01). The regrowth of antler in both Sika deer and Elk occurred in the MPA injection and the duration of antler growth was 2 times longer than control. The total yield of velvet antler of Elk in the control and MPA injection was 7.31 and 10.11kg and the that of sika deer was 1.00 and 1.41kg, respectively. Blood testosterone concentration of Sika deer and Elk was less than 4.0ng/ml for both at the casting and during the antler growing. Blood IGF-1 concentrations of Sika deer and Elk during the antler growing tended to increase with the same as growth curve of antler.

A four-year-old male elk (Cervus elaphus nelsoni) was diagnosed as pulmonary aspergillosis and renal oxalosis. Clinical signs were coughing, sneezing, respiratory distress, salivation, moderate anorexia, and progressive emaciation. Main gross lesions were fibrinopurulent tonsillitis, diffusely fibrinous pleuritis, and distinct lobar pneumonia with purple red in color. Most of the pulmonary lobes had numerous well demarcated 0.5 to 2 cm yellowish white discrete or confluent nodules that were surrounded by pale red zones. Histopathologically, the affected lungs were disseminated necrotizing pyogranulomas including fungal hypae, vasculitis, and diffusely fibronecrotic pleuritis. The renal lesions were composed of extensive tubular necrosis with large numbers of rosette-formation by birefringent oxalate crystals. Aspergillus fumigatus was isolated from lesions of the lungs. It seems to be a first report for pulmonary aspergillalis and renal oxalosis of a farmed elk in Korea.

A thirty-five week old elk was referred for Chronic Wasting Disease (CWD) confirmation from Chungnam province in Korea. Necropsy revealed much bloody contents in the lumen of small and large intestines, and reddening of its mucosa. Microscopically, few coccidia showing various developmental stages were infiltrated in lamina propria of small intestine with granulomatous inflammation and congestion. They were identified as Eimeria spp. according to their location and morphological characteristics. Because fecal examination and oocyst culture were not available, the species of the Eimeria could not be confirmed. There were no detection of pathogenic bacteria such as clostridia and virus in intestinal contents. CWD was shown to be negative in immunohistochemistry test. In conclusion, it was the first Eimeria case detected in small intestine of Korean domestic elk as far as we know although Eimeria spp. were not the main cause of death.

Authors encountered a case of elk babesiosis in Daegu, Korea. The main symptoms observed before the death of the patient were elevated rectal temperature, severe degree of hemoglobinuria, icterus and recumbency. Hematologically, the erythrocyte count was 1.93 million per cu.mm 11% of which were infected with Babesia. Most(88%) of the protozoa were spherical or vacuolated ring form in shape, resembling B. bovis. However, the sizes (0.98-2.85) were slightly smaller than the latter. About 7% of the protozoa were vacuolated oval, the size of which varied from $2.06{\sim}2.95{\times}1.08{\sim}1.97$ ($2.53{\times}1.51$ in average). The remaining 5% were irregular in shape. Pear-shaped were scarcely observed. A three-gears-old Korean native cattle was inoculated subcutaneously with the elk's blood. However, no evidence of susceptibility was observed until 30 days postinoculation.

With the development of IT, hacking crimes are becoming intelligent and refined. In Emergency response, Big data analysis in information security is to derive problems such as abnormal behavior through collecting, storing, analyzing and visualizing whole log including normal log generated from various information protection system. By using the full log data, including data we have been overlooked, we seek to detect and respond to the abnormal signs of the cyber attack from the early stage of the cyber attack. We used open-source ELK Stack technology to analyze big data like unstructured data that occur in information protection system, terminal and server. By using this technology, we can make it possible to build an information security control system that is optimized for the business environment with its own staff and technology. It is not necessary to rely on high-cost data analysis solution, and it is possible to accumulate technologies to defend from cyber attacks by implementing protection control system directly with its own manpower.
