Security Concern

The issue of data security seems to be one of the most intriguing topics to observe in the development of information technology in recent time/. The information technology related to the management processes, one of which is the SIMAK application at   the University of Siliwangi needs a higher security concern. This study aims to determine the level of security of the SIMAK application in which the researchers can provide recommendations to SIMAK managers. This could be the basis for the future improvements. Researchers used 4 domains from ISO / IEC 27002: 2013, namely domain 5, it contains information security policies. Domain 6, it contains organizational information security. Domain 9, it contains access control. Lastly, Domain 11, it contains physical and environmental security.  When they are specified from the four domains, 38 controls are obtained. Security, from the results of the questionnaire and weighting, the result of the 5 domains maturity value is= 1.49, the result of the domain 6 maturity value is= 1.52, while domain 9 maturity value is= 1.32 and domain 11 maturity value constitute to 1.97.  If it is averaged,  the Siliwangi University SIMAK application is at level 2 or repeatable.

Different Parts

The issues related to network data security were identified shortly after the inception of the first wired network. Initial protocols relied heavily on obscurity as the main tool for security provisions. Hacking into a wired network requires physically tapping into the wire link on which the data is being transferred. Both these factors seemed to work hand in hand and made secured communication somewhat possible using simple protocols. Then came the wireless network which radically changed the field and associated environment. How do you secure something that freely travels through the air as a medium? Furthermore, wireless technology empowered devices to be mobile, making it harder for security protocols to identify and locate a malicious device in the network while making it easier for hackers to access different parts of the network while moving around. Quite often, the discussion centered on the question: Is it even possible to provide complete security in a wireless network? It can be debated that wireless networks and perfect data security are mutually exclusive. Availability of latest wideband wireless technologies have diminished predominantly large gap between the network capacities of a wireless network versus a wired one. Regardless, the physical medium limitation still exists for a wired network. Hence, security is a way more complicated and harder goal to achieve for a wireless network (Imai, Rahman, & Kobara, 2006). So, it can be safely assumed that a security protocol that is robust for a wireless network will provide at least equal if not better level of security in a similar wired network. Henceforth, we will talk about security essentially in a wireless network and readers should assume it to be equally applicable to a wired network.

Information security is a prime goal for every individual and organization. The travelling from client to cloud server can be prone to security issues. The big data storages are available through cloud computing system to facilitate mobile client. The information security can be provided to mobile client and cloud technology with the help of integrated parallel and distributed encryption and decryption mechanism. The traditional technologies include the plaintext stored across cloud and can be prone to security issues. The solution provided by applying the encrypted data upload and encrypted search. The clouds can work in collaboration; therefore, the encryption can also be done in collaboration. Some part of encryption handle by client and other part handled by cloud system. This chapter presents the security scenario of different security algorithms and the concept of mobile and cloud computing. This chapter precisely defines the security features of existing cloud and big data system and provides the new framework that helps to improve the data security over cloud computing and big data security system.

Driven by the difficulty in achieving complete security with technical tools, business investigators are looking into organizational and behavioral issues that could help make systems more secure. This chapter looks at the security of systems from the organizational perspective. Specifically, this study attempts to identify if different organizations have different predisposition to particular type(s) of security threat sources. Using publicly available security breach data from a privacy rights clearinghouse to investigate which organizational characteristics predisposes an institution to an external or internal threat source, it was concluded that as size of organization and the number of its valuable documents increase by one unit, the organization's probability of suffering an internal attacks decrease. Furthermore, when executive members have a business degree rather than information-security-related degrees, the likelihood of suffering an internal attack increases. Also, the probability of an organization suffering an internal or external attack is not based on its industry type.

Currently, information security inspection can only be conducted via network scan using a laptop, which results in a low-efficient one-by-one check, and moreover lacks the ability to locate wireless networks and not to mention technical measures to discover hidden networks. With respect to the regulations of a power supply enterprise regarding wireless network security, combined with the operation and maintenance comprehensive supervision system (IMS), and the information extranet security monitoring system (ISS), a cascading wireless network security inspection platform is studied and implemented. This paper describes the wireless network encryption technology, and details the deployment pattern and the work flow, etc. about the wireless network security inspection platform. Experiments show that the platform provides support for the information security supervision work of wireless networks and can effectively safeguard the security of wireless networks in a power enterprise.

Abstract: Data is any type of stored digital information. Security is about the protection of assets. Data security refers to protective digital privacy measures that are applied to prevent unauthorized access to computers, personal databases and websites. Cryptography is evergreen and developments. Cryptography protects users by providing functionality for the encryption of data and authentication of other users. Compression is the process of reducing the number of bits or bytes needed to represent a given set of data. It allows saving more data. Cryptography is a popular ways of sending vital information in a secret way. There are many cryptographic techniques available and among them AES is one of the most powerful techniques. The scenario of present day of information security system includes confidentiality, authenticity, integrity, nonrepudiation. The security of communication is a crucial issue on World Wide Web. It is about confidentiality, integrity, authentication during access or editing of confidential internal documents. Keywords: Cryptography, Hill Cipher, Homophonic Substitution Cipher, Monoalphabetic Cipher, Ceaser Cipher.
