Motion detectors are sensors that record movement in a certain area. This study proposes the evaluation of three motion detectors, using the Arduino microcontroller to execute orders to the sensors infrared, PIR (passive infrared sensor) and ultrasonic, to determine the obstacle detection behavior against different objects. According to the tests carried out and the theory presented for each sensor, we have found that the most efficient sensor for object detection is the PIR, due to its scope and viewing angle, which represents being feasible and more reliable to implement; for example, in security systems.

Purwarupa sistem ini dilatar belakangi karena kurangnya sistem keamanan yang memadai sehingga terjadi tindakan pencurian dan penghuni asrama atau kost membawa teman tanpa seizin pemilik kost. Sistem ini mengimplementasikan pola sidik jari penghuni yang telah terdaftar. Dengan menggunakan satu pola sidik jari dipastikan tidak membawa lebih dari satu orang, sehingga sistem dapat mengizinkan akses masuk kost atau asrama maupun menolak akses masuk karena ada orang lain yang tidak terdaftar.Pengujian sistem dilakukan setiap hari dengan menggunakan beberapa sampel pola sidik jari penghuni yang diambil oleh alat sensor sidik jari Fingerspot U.are.U 4500.Pendeteksian orang menggunakan sensor Passive Infrared Receiver dengan bantuan sensor photodiode untuk menghitung jumlah orang.Untuk mempermudah pendeteksian digunakan sistem minimum ATMega16 dan bahasa pemrograman Bascom AVR.Microsoft Visual Basic 6 digunakan sebagai antarmuka sehingga dapat berinteraksi dengan alat. Data yang telah diambil selanjutnya disimpan dalam basis data menggunakan MySQL dan Microsoft Access 2007.The prototype of this system is due to the lack of adequate security systems in the boarding house that there was a theft and tenants bring their friends without the permission of the owner of the boarding house. This system is based on fingerprint patterns of the tenants who have been registered. By using a fingerprint pattern for security mechanism, a tenant will not be able to bring his/her friends without permission.The system is implemented using Fingerspot U.are.U 4500 as the fingerprint reader. The presence and number of people is detected using Passive Infared Receiver and photodiode. In order to simplify the system, detection of people is implemented using ATMega16 as minimum system and Bascom AVR as programming language. Microsoft Visual Basic 6 is used for interaction with the interface. The data whisch have been taken are stored in Microsoft Access 2007 and MySQL.

End of Line Resistor (EOLR) is a resistor that has a certain value to protect the circuit at the end of a loop or zone. The End of Line Resistors is used in security systems to enable the control panel to monitor wiring of open and closed. In this research using an Arduino microcontroller and Passive Infrared (PIR) Motion Sensor that connected with the systematic circuit to supervisory a loop or zone. Systematic circuit use combination of the resistor as the end of line resistor and voltage divider method. Analog input on Arduino uses to detect different states of sensors. The 1K resistor in series with the sensor line provides some protection for the input pin against the unexpected current flow. The 4K7 pull-up resistor, when combined with the resistance provided by the sensor, acts as a voltage divider, exposing the analog input to a different voltage depending on the state of the sensor. The result of measurement viewed by serial monitor function on the personal computer. PIR Sensor connected with an analog pin on microcontroller running well and there is no significant voltage value changing.

Pros And Cons

The multi-pattern matching is a fundamental technique found in applications like a network intrusion detection system, anti-virus, anti-worms and other signature- based information security tools. Due to rising traffic rates, increasing number and sophistication of attacks and the collapse of Moore’s law, traditional software solutions can no longer keep up. Therefore, hardware approaches are frequently being used by developers to accelerate pattern matching. Reconfigurable FPGA-based devices, providing the flexibility of software and the near-ASIC performance, have become increasingly popular for this purpose. Hence, increasing the efficiency of reconfigurable information security tools is a scientific issue now. Many different approaches to constructing hardware matching circuits on FPGAs are known. The most widely used of them are based on discrete comparators, hash-functions and finite automata. Each approach possesses its own pros and cons. None of them still became the leading one. In this paper, a method to combine several different approaches to enforce their advantages has been developed. An analytical technique to quickly advance estimate the resource costs of each matching scheme without need to compile FPGA project has been proposed. It allows to apply optimization procedures to near-optimally split the set of pattern between different approaches in acceptable time.

Subject. The article discusses the modeling of preventive protection of IT systems and evaluates their cyber resilience. Objectives. The study evaluates the existing threats and determines how informatization processes may unfold in the credit segment. Methods. Research is based on methods of regulatory and legislative analysis. We evaluate today’s public administration of cybersecurity in the financial and credit sector. To give a view of the existing situation and sum up the sector’s performance for the recent years, we performed the content analysis of statistics on data hacking and leakages. Results. The article highlights new trends in the financial and credit sector and the growing complexity of data security systems. As proposed by the Bank of Russia, the integration of smart technologies is showed to reinforce the cybersecurity of banking systems. Conclusions and Relevance. The informatization of all banking operation systems, growing complexity of procedures and work logs require new robust resources to be integrated into financial technologies. Stronger cybersecurity should lay a trend in the financial and credit sector in the nearest future. The findings can be used to flag strategic milestones of the banking development in the information-driven society.

الملخّص يهدف هذا البحث لبيان أن السبيل الناجح لمواجهة الإرهاب الدولي المعاصر الملتبس بدعاوي الجهاد الإسلامي وإحياء دولة الخلافة الإسلامية هو التركز على معاني الأمن الفكري والروحي في الإسلام وهذا الاتجاه في المباحثة يُعيد النظر في طرائق قضايا الجهاد ويميز بين ما هو عقائدي ومرتبط بنظام الإسلام الكلي وبين ما هو من مجال حروب الفتنة والصعلكة.  الكلمات المفتاحيّة: الجهاد، حروب الصعلكة، حروب الفتنة، الأمن الروحي والفكري.              Abstract This study focuses on the most effective way of combating global terrorism that utilizes the banner of Jihad and restoration of the Khilafa system of governance. It should be emphasized that there is a dire need for a new line of investigation concerning the issue of Jihad that pays more attention to both spiritual and intellectual security systems in Islam. This requires a distinction to be made between what is universalistic in the Islamic system and what is particular. In this regard one has to differentiate between acts of just war and those of economic or sedition wars. Keywords: Jihad, economic war, sedition war, spiritual-intellectual security system.
