Information is the most important asset that owned by an organization. In the era of the technology development that increase rapidly, all information can be stored and managed digitally. This makes the informationmanagement process within the organization become more effective and efficient. On the other side, informationsecurity is an absolute thing to be fulfilled by the organization. Leakage of information on an organization will have an adverse effect on the sustainability of the organization. Informationsecurity must include the CIA aspects (Confidentiality, Integrity, and Availability). With the rapid development of technology, threats to aspects of C.I.A (Confidentiality, Integrity, and Availability) in an organization are also getting higher. If one of the aspects of C.I.A cannot be fulfilled by the organization, then the accuracy and availability of information on the organization will be questioned and the trust of the users of that information will decrease so that it has a major impact on the operational continuity of the organization. STMIK STIKOM Bali is a university in the field of Information Technology in Bali which currently has more than 5000 students. This makes STIKOM Bali's informationmanagement complexity quite high, so that the informationsecurity aspects of STI KOM Bali become very important. But until now there has not been a good and structured informationsecuritymanagement based on informationsecurity standards for an organization. In this study, an informationsecuritymanagement analysis process was carried out on the information technology infrastructure in STMIK STIKOM Bali, and the results is the measurement of the maturity level were 1.72 (Initial / Ad Hoc)
Boss et al., (2009) introduced the concept of mandatoriness, which has been shown to motivate individuals to take security precautions. Despite the importance of ISA, there is a paucity of empirical studies that analyze the impact of ISA on informationsecurity. Siponen (2006) conceptually analyzed ISA and suggested methods to enhance awareness. A few conceptual studies (Furnell et al., 2006; Hentea, 2005; Thomson and Von Solms, 1998) have highlighted the importance of ISA education and training. Puhakainen and Ahonen (2006) proposed a design theory for improving ISA campaigns and training. D’Arcy et al. (2009) suggested that organizations can use three security countermeasures—user awareness of security policies; security education, training, and awareness programs; and com- puter monitoring—to reduce user’s misuse. Beyond showing the direct influence of ISA on an employee’s attitude towards compliance, the countermeasures aim to understand the antecedents of compliance by disentangling the relationships between ISA and an employee’s outcome beliefs about compliance and noncom- pliance. For instance, ISA issues within organizations were apparent in the report by Potter and Beard (2012), where it stated that ‘incidents caused by staff’ were experienced by 82% of the sampled large organizations.
InformationSecurityManagement System (ISMS) adalah seperangkat kebijakan berkaitan dengan manajemen keamanan informasi atau terkait dengan risiko TI. Prinsip yang mengatur di balik ISMS adalah bahwa organisasi harus merancang, menerapkan dan memelihara seperangkat kebijakan, proses dan sistem untuk mengelola risiko aset informasi mereka, sehingga memastikan tingkat risiko keamanan informasi yang dapat diterima. Dari perencanaan dan implementasi sistem manajemen keamanan informasi ini, dihasilkan daftar nilai risiko akhir aset- aset kritikal dan dokumen-dokumen tata kelola penunjang ISMS. Metode penelitian yang digunakan adalah studi kasus yang didalam hal ini, merupakan penelitian kualitatif. Adapun proses yang digunakan untuk mengukur tingkat kematangan dari tata kelola keamanan sistem informasi ini berdasarkan kerangka kerja ISO/IEC 27001. Dari kerangka tersebut kemudian dilakukan evaluasi terhadap objek kontrol yang dimiliki ISO/IEC 27001. Hasil yang didapat adalah peningkatan terhadap tata kelola keamanan sistem informasi. Kesimpulan dari penelitian ini adalah dibutuhkannya tata kelola keamanan sistem informasi agar IT dapat diandalkan untuk mencapai tujuan bisnis.
¾ Kebijakan keamanan, atau dalam bahasa Inggris disebut sebagai Security Policy. Contoh kebijakan keamanan ini misalnya adalah sebagai berikut: Semua kejadian pelanggaran keamanan dan setiap kelemahan sistem informasi harus segera dilaporkan dan administrator harus segera mengambil langkah-langkah keamanan yang dianggap perlu. Akses terhadap sumber daya pada jaringan harus dikendalikan secara ketat untuk mencegah akses dari yang tidak berhak. Akses terhadap sistem komputasi dan informasi serta periferalnya harus dibatasi dan koneksi ke jaringan, termasuk logon pengguna, harus dikelola secara benar untuk menjamin bahwa hanya orang/ peralatan yang diotorisasi yang dapat terkoneksi ke jaringan.
All the critical success factors support the importance of setting up the InformationSecurityManagement Committee that emphasize on the criticality of having inputs from all the departments throughout organization. The inputs from various departments are important to achieve the following goals:
understanding the field of InformationSecurity. This is accomplished by explaining the importance of information technology and defining who is responsible for protecting an organization’s information assets. In this chapter the student will come to know and understand the definition and key characteristics of informationsecurity as well as the come to recognize the characteristics that differentiate informationsecuritymanagement from general management.
Everyone have roles and responsibilities for maintaining security in organization. The management, technical people, employees, vendors and contractors have different roles in developing and implementing an effective security process. For this article, we will look at the roles and responsibilities of management, InformationSecurity Department and users in implementing and maintaining informationsecuritymanagement system (ISMS) in organization.
brainstorming sessions to review the threat landscape. The output from these sessions is a list of “top risks.” Security resources are then focused on mitigating the items on the list. There are several problems with this approach. Information comes from a narrow, limited range of sources, resulting in a blinkered security perspective that tends to stifle creative thinking. Also, the information is usually fragmented, making it difficult for the team to identify trends and gaps in the data. These deficiencies continue through security planning and implementation. Because the team lacks a full view of the threat landscape, it’s hard to determine which threats require immediate attention and how much of the limited security budget they deserve. As a result, risks are incorporated into plans on an ad hoc basis, and not all risks are adequately mitigated. Finally, security teams often don’t have a structured process for communicating threat information to other people within their organizations. Because of this, people outside the security group remain unaware of emerging risks and don’t know how to respond when they experience an attack.
As part of this white paper, a survey conducted on senior executives from around the world with security concerns was found in an article by Rudolph W.Giulani “Testing The Defences For Corporate Security”. The Economist Inteligence Unit (2003). The finding in this research by Giuliani reveals some interesting inconsistencies in Management thinking on InformationSecurity. The majority of executives for example, believe computer viruses are the most frequent and damaging form of security threat and incident. According to this finding, their believes are only partly right. In reality, theft of proprietary information is much more costly evil. In addition, the findings also mentioned that most security incidents are mostly accidental than deliberate.
Based on the preliminary survey conducted by researchers at the Hospital ManagementInformation System in Sukoharjo District Hospital in medical records in terms of data security is still going according to theory, among others, medical records officers do not yet have their own username and password - alone. The system is not equipped with automatic logging off and the system is also not equipped with a search feature trail. This type of research is descriptive. His re- search is SIMRS data security systems. The object of the research is admin and user SIMRS of SIMRS in medical records. The research instrument used is the observation guidelines. The data collected by observation and interviews were unstructured. Data processing techniques of data collection, editing and presentation of data. Data processing descrip- tively. The results based on observations and interviews in Sukoharjo District Hospital, the hospital has not had a policy on hospital managementinformation system. The clerk at the medical records do not have a username and password. Admin disallow access rights to users. Computers have been installed antivirus. There are no traces of search features. Backing up data is done automatically. One server computer storage space with IT space as well as data transmission using the LAN. Advice from researchers is Sukoharjo district hospitals to publish a policy on hospital managementinformation system so that officers have guidelines in work, each user is expected to have a username and password alone - alone, the system is expected to have a search feature and a computer trail is expected to have an auto log off.
An important element in any security system is the business continuity plan An important element in any security system is the business continuity plan, also known as the disaster recovery plan. Such a plan outlines the process by which businesses should recover from a major disaster.

The two SHA-3 XOFs are designed to resist collision, preimage, and second-preimage attacks, and other attacks that would be resisted by a random function of the requested output length, up to the security strength of 128 bits for SHAKE128, and 256 bits for SHAKE256. A random function whose output length is d bits cannot provide more than d /2 bits of security against collision attacks and d bits of security against preimage and second preimage attacks, so SHAKE128 and SHAKE256 will provide less than 128 and 256 bits of security, respectively, when d is sufficiently small, as described in Table 4. For example, if d = 224, then SHAKE128 and SHAKE256 provide 112 bits of collision resistance; however, they provide different levels of preimage resistance: 128 bits for SHAKE128 and 224 bits for SHAKE256.
Ideally, information reduces uncertainty about a state or event. For example, information that the wind is calm reduces the uncertainty that the boat trip will be pleasant. An information system is the basis for interaction between the user and the analyst. It provides instruction, commands and feedback. It determines the nature of the relationships among decision-makers. In fact, it may be viewed as a decision center for personnel at all levels. From this basis, an information system may be defined as a set of devices, procedures and operating systems designed around user based criteria to produce information and communicate it to the user for planning, control and performance. In systems analysis, it is important to keep in mind that considering an alternative system means improving one or more of these criteria.
• Incorrect or inadequate classification of some assets and information. Somewhere there is often a detailed map of your full network, or a full security plan, complete with information on every layer of security present. That can act just like a building blueprint for identifying the weakest and most vulnerable points of entry. Maybe there is a network device that is the gateway to your most classified and confidential information. Often information like this is maintained with much lower security than the information they protect. For example, I have frequently been given security and network plans like this during an external audit. Although these document are designed to evidence a strong security posture, granting access to this document, even having it all in one place is evidence to the contrary.
interests of its customers. Currently there are no "consumer reports" for security products and services, so it can be difficult to prove a product's worth. In the absence of empirical ways to do so, the security industry has historically used sales tactics such as appealing to fear. Perhaps this is not so different from other markets. It may also be that vendors truly believe that their product or service is a panacea or the ultimate solution— that the ends (better security) justifies the means. But even if they are right, the net result is not positive. Companies scared by security risks and led astray by vendor marketing are likely to spend very inefficiently. When acting as a consultant, one of the authors has on several occasions been told by companies that they have no time to document their environment, and then shortly thereafter been asked what brand of new security product they should buy. What would ultimately be more
Although big data security is immature today, we believe, with concerted effort from industries, governments, academicians, and practitioners, big data security will improve over time to meet those challenges discussed in this chapter. Similar to the case of Internet security, which is an afterthought when the need for security became critical and evident. The initial Internet architecture had little consideration for security and privacy. However, as Internet and the World-wide Web grew exponentially in the 1990s, multi-layer Internet security protocols were developed and those security standards helped facilitating the growth of the Internet and Internet applications. We are optimistic that big data security will follow a similar path. This chapter provides basic concepts, principles, challenges, and current issues of big data security. We hope it serves as a launching pad for advancing big data security research in the future.
In the logical design phase, team members create and develop the blueprint for security, and examine and implement key policies that influence later decisions. In the physical design phase, team members evaluate the technology needed to support the security blueprint, generate alternative solutions, and agree upon a final design.
The era of globalization brought about changes in the development of information technology systems, invariably affect business activities in order to be at pace with the global world (Babatunde & Selamat, 2011 & 2012). So, this paper confers on the investigation of accounting informationsecurity activities and the establishment of an informationsecurity culture in an organizational setting. The goal of this paper absolutely is to illuminate on informationsecurity projects, establishment of informationsecurity culture and the imperative of updating technological systems of the banking industry from the perspective of Nigeria as a developing country. Conversely, the challenges Nigerian banks encompassed with non-compliance with the international security standards as a result of lack of establishment informationsecurity culture, thereby led to fraud perpetration within the management. So, the governing council of Central bank of Nigeria is seeking to eradicate frauds to the minimum level. Also, the need to establish an informationsecurity culture with the organization and to update the users of technological systems meet the global world to achieve the highest key performance indicator (KPI).
Technical requirements, such as those for the cleaning of new hard discs, form one of the two sections of this standard. On the whole, these requirements are specific to the laboratory being audited and will include baseline competencies in technical operations for all staff working in the laboratory. This ensures everyone is trained and that training is regularly refreshed in a way that is appropriate to individual roles. It is also possible, depending on the work being carried out in the laboratory, that there will be a requirement for proficiency testing between compliance evaluations by their accreditation body. This means that staff must demonstrate their skills in certain key activities together with their on-going personal development in the area in which they are operating. A straightforward check that might be helpful for a ‘visiting auditor’ from a customer organisation, who may have limited knowledge of the process happening in the lab, is to see that all the processes being carried out are covered by the terms of the existing accreditation and that the laboratory has not operated outside of the work they were certified to carry out. The second part of this standard focuses on management requirements. This is vital because the technical system might be entirely compliant, but if the way that tasks are carried out is not appropriately managed then the standard of the actual operation is at risk of inadequacy. This part relates to the ISO 17025 ‘operation and effectiveness of the operation management system’ 4 and will be along similar lines to any
