This paper deals with the android application security detection method, based on the permissions .Mobile applications create their own security and privacy models through permission-based models. Some applications may request extra permissions that they do not need but may use for suspicious activities. The aim of this study is to identify those spare permissions requested and use this information in the security and privacy approach. To combat serious malware campaigns, we need a scalable malware detection approach that can effectively and efficiently identify malware apps. The proposed method based on metropolis algorithm with twalk is to provide the detection method for the android security of the applications based on the permissions that the applications request from the users during installations. This method helps to speedup detection and also increasing the sampling rate. Accuracy, precisions and recall values are calculated using true and false positive and negativerates depending on which this model is selected to detect the security of the android application.

Network security is the process of taking physical and software preventative measures to protect the underlying networking infrastructure from unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure, thereby creating a secure platform for computers, users, and programs to perform their permitted critical functions within a secure environment. A local area network (LAN) is a computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings. A LAN is composed of inter-connected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices, anywhere on the LAN. LANs are characterized by higher communication and data transfer rates and the lack of any need for leased communication lines. A data network is an interconnected system of computers, peripherals and software over which data files and messages are sent and received. LAN is only one type of computer network. LAN define is Data com system allowing a number of independent devices to communicate directly with each other, within a moderately sized geographic area over a physical communications channel of moderate data rates. Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared light through an optical fiber. The light is a form of carrier wave that is modulated to carry information. Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances. Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Researchers at Bell Labs have reached a record bandwidth distance product of over 100 petabit × kilometers per second using fiber optic communication. Communication between remote parties can be achieved through a process called Networking, involving the connection of computers, media and networking devices. When we talk about networks, we need to keep in mind three concepts, distributed processing, network criteria and network structure. The purpose of this Network is to design a Local Area Network (LAN) for a BAEC (Bangladesh Atomic Energy Commission) Head Quarter and implement security measures to protect network resources and system services. To do so, we will deal with the physical and logical design of a LAN. The goal of this Network is to examine of the Local Area Network set up for a BAEC HQ and build a secure LAN system.

We live in age of modern science. Computer Network is the best innovation of Modern science. A local area network (LAN) is a computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings. A LAN is composed of inter-connected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices, anywhere on the LAN. LANs are characterized by higher communication and data transfer rates and the lack of any need for leased communication lines. A high-quality and correctly dimensioned network infrastructure is essential for all well- functional IT system. A Local Area Network based network can ensure high speed as well as high quality network. To fulfill the current requirements of AERE (Atomic Energy Research Establishment) considering its smooth operation of high speed internet service, LAN based network is the state-of-the-art network solution. A LAN network design refers to the specialized processes leading to a successful installation and operation of a network which includes determining the type of communication system(s) which will be carried over the network, the geographic layout, the transmission equipment required and the fiber network over which it will operate. The purpose of this Network is to design a Local Area Network (LAN) for AERE (Atomic Energy Research Establishment) and implement security measures to protect network resources and system services. To do so, I will deal with the physical and logical design of a LAN. The goal of this Network is to examine of the Local Area Network set up for AERE and build a secure LAN system.
