Members and ISACA Certification holders shall:

■ Support the implementation of, and encourage compliance with, appropriate standards, procedures and controls for information systems.

■ Perform their duties with due diligence and professional care, in accordance with professional standards and best practices.

■ Serve in the interest of stakeholders in a lawful and honest manner, while maintaining high standards of conduct and character, and not engage in acts discreditable to the profession.

■ Maintain the privacy and confidentiality of information obtained in the course of their duties unless disclosure is required by legal authority. Such information shall not be used for personal benefit or released to inappropriate parties.

■ Maintain competency in their respective fields and agree to undertake only those activities, which they can reasonably expect to complete with professional competence.

■ Inform appropriate parties of the results of work performed; revealing all significant facts known to them.

■ Support the professional education of stakeholders in enhancing their understanding of information systems security and control.

RELATIONSHIP OF STANDARDS TO GUIDELINES AND PROCEDURES

IS Auditing Standards are mandatory requirements for certification holders’ reports on the audit and its findings. IS Auditing Guidelines and Procedures are detailed guidance on how to follow those standards. The IS Auditing Guidelines are guidance an IS Auditor will normally follow with the understanding that there may be situations where the auditor will not follow that guidance. In this case, it will be the IS Auditor’s responsibility to justify the way in which the work is done. The procedure examples show the steps performed by an IS Auditor and are more informative than IS Auditing Guidelines. The examples are constructed to follow the IS Auditing Standards and the IS Auditing Guidelines and provide information on following the IS Auditing Standards. To some extent, they also establish best practices for procedures to be followed.

The audit program is designed to address the primary risks of virtually all computing systems. Therefore, the objective statement and steps in the program are general by design. Obviously, computing systems can have many different applications running on them, each with its own unique set of controls. However, the controls surrounding all computing systems are very similar. The IS controls in the audit program have been grouped into four general categories:

Objective:

1. To assess the adequacy of environmental, physical security, logical security, and operational controls designed to protect IS hardware, software, and data against unauthorized access and accidental or intentional destruction or alteration, and
2. to ensure that information systems are functioning in an efficient and effective manner to help the organization achieve its strategic objectives.

TESTS OF ENVIRONMENTAL CONTROLS

Step 1. Assess the adequacy and effectiveness of the organization’s IS security policy. In addition, assess whether the control requirements specified in the organization’s IS security standards adequately protect the information assets of the organization. At a minimum, the standards should specify the following controls and require them to
be applicable to all information systems:

a. The maiden password should be changed after the system is installed.

b. There is a minimum password length of eight or more characters.

c. Passwords require a combination of alpha and numeric characters.

d. The password is masked on the screen as it is entered.

e. The password file is encrypted so nobody can read it.

f. There is a password expiration period of 60 days or less.

g. Three or fewer unsuccessful sign-on attempts are allowed, then the user ID is suspended.

h. User sessions are terminated after a specified period of inactivity (e.g., five minutes or less).

i. Concurrent sign-on sessions are not allowed.

j. Procedures are in place to remove user IDs of terminated users in a timely manner.

k. Users are trained not to share or divulge their passwords with other users, post them in their workstations, store them in eletronic files, or perform any other act that could divulge theirpasswords.

l. Unsuccessful sign-on attempts and other logical security-related events (e.g., adding and deleting users, resetting passwords, restarting the system) are logged by the system, and the log is reviewed regularly by system security staff.

m. Fully developed and tested backup and recovery procedures exist to help ensure uninterrupted business resumption in the event of a full or partial disaster.

n. New information systems are required to be designed to enable the aforementioned controls to be implemented by system security administrators. New systems include those developed in house, those purchased from vendors, and third-party processor systems. In the case of software vendors and third-party processors,the above control requirements should be specified as requirements in the contract.

Step 2. For service organization applications, examine the most recent report in the policies and procedures placed in operation at the vendor’s data processing site as prepared by its external auditors. In the United States, the format and testing requirements are dictated by Statement on Auditing Standards 70 (SAS 70), issued by the American Institute of Certified Public Accountants.

Step 3. If the system was purchased from and supported by a vendor, assess the financial stability of the system vendor using the most recent audited financial statements prepared by the vendor’s external auditors.

Step 4. Examine the vendor software license agreement and any agreements for ongoing maintenance and support to ensure that they are current, address service needs, and do not contain or omit any wording that could be detrimental to your organization.

TESTS OF PHYSICAL SECURITY CONTROLS
Step 5. Assess the adequacy of physical security over the computer system hardware and storage media.

Step 6. Determine whether an adequately trained backup system security administrator has been designated.

Step 7. Assess the adequacy and effectiveness of the written business resumption plan, including the results of mock disaster tests that have been performed.

Step 8. Assess the adequacy of insurance coverage over the hardware, operating system, application software, and data.

TESTS OF LOGICAL SECURITY CONTROLS
Step 9. Determine whether the maiden password for the system has been changed and whether controls exist to change it on a periodic basis in conformity with the computing system security policy, standards, or guidelines identified in Step 1.

Step 10. Observe the system security administrator sign on and print a list of current system users and their access capabilities. Alternatively, if you can obtain appropriate system access, you can obtain the list of users independently.

Step 11. Document and assess the reasonableness of the default system security parameter settings. The settings should conform to the organization’s computing system security policy, standards, or guidelines tested in Step 1. (Be alert to the fact that in some systems, individual user parameter settings override the default system security
parameter settings.)

Step 12. Test the functionality of the logical security controls of the system (e.g., password masking, minimum password length, password expiration, user ID suspended after successive invalid sign-on attempts, log-on times allowed, and session time-outs).

Step 13. Determine whether the file containing user passwords is encrypted and cannot be viewed by anyone, including the system security administrator.

Step 14. Determine whether sensitive data, including passwords, are adequately
encrypted throughout their life cycles, including during storage, transmission through any internal or external network or telecommunications devices, and duplication on any backup media.

Step 15. Assess the adequacy of procedures to review the log of system security-related events (e.g., successive invalid sign-on attempts, system restarts, changes to user access capabilities and user parameter settings).

Step 16. Assess the adequacy of remote access controls (e.g., virtual private networks [VPNs], token devices [CRYPTOCard, SecurID, etc.], automatic dial-back, secure sockets layer [SSL]).

TESTS OF INFORMATION SYSTEMS OPERATING CONTROLS
Step 17. Determine whether duties are adequately segregated in the operating
areas supporting the information system (e.g., transactions should be authorized only by the originating department, programmers should not have the capability to execute production programs, procedures should be adequately documented, etc.).

Step 18. Determine whether there have been any significant software problems with the system. Assess the adequacy, timeliness, and documentation of resolution efforts.

Step 19. Assess the adequacy of controls that help ensure that IS operations are functioning in an efficient and effective manner to support the strategic objectives and business operations of the organization (e.g., system operators should be monitoring CPU processing and storage capacity utilization throughout each day to ensure that adequate reserve capacities exist at all times).

The Pacific Symposium on Biocomputing (PSB) is an international, multidisciplinary conference for the presentation and discussion of current research in the theory and application of computational methods in problems of biological significance. Papers and presentations are rigorously peer reviewed and are published in an archival proceedings volume. PSB 2008 will be held January 4-8, 2008 at the Fairmont Orchid on the Big Island of Hawaii. Tutorials will be offered prior to the start of the conference.

PSB 2008 will bring together top researchers from the US, the Asian Pacific nations, and around the world to exchange research results and address open issues in all aspects of computational biology. PSB is a forum for the presentation of work in databases, algorithms, interfaces, visualization, modeling, and other computational methods, as applied to biological problems, with emphasis on applications in data-rich areas of molecular biology.

The PSB has been designed to be responsive to the need for critical mass in sub-disciplines within biocomputing. For that reason, it is the only meeting whose sessions are defined dynamically each year in response to specific proposals. PSB sessions are organized by leaders in the emerging areas and targeted to provide a forum for publication and discussion of research in biocomputing’s “hot topics.” In this way, PSB provides an early forum for serious examination of emerging methods and approaches in this rapidly changing field.

ComputerWorld : “Green IT” at the top of its list of 10 strategic technologies for next year, and the research firm says that if businesses don’t improve data center energy efficiency, the government may force them to do so.But social networking technologies are also on the list, along with some further-off technological developments, such as server designs that use a resource-sharing approach called a computing fabric.

A strategic technology is something that may have an impact on a business. And impact could mean driving an investment or posing a threat.

Here’s a look at list:

1. Green IT. This is a path that more and more companies are taking as a socially responsible strategy. A green approach is multifaceted and can affect data center operations in a number of ways, such as moving workloads based on energy efficiency and using the most power-inefficient servers only at times of peak usage. But data centers also face the threat of regulatory action to curb power usage. The problem is you can’t predict what may trigger regulation or when mandates will arrive.

2. Unified communications. The move to unified communications systems is happening as the world shifts from analog to digital over IP networks. But it’s not just the obvious things that will converge, such as telephony and messaging. Companies may make security videos part of this convergence, which may give businesses, for instance, new ways to analyze a retail outlet’s traffic patterns. This video data would require a lot of storage, so using it in this way could prompt IT managers to introduce the security team to the networking group.

3. Business process management. This is not a technology, its a way of using technologies to enable companies to simulate, model and design the processes that run their businesses. A key trend is the evolution of the business process management suite, Cearley said. This may include, model-driven development, content and document management, collaboration capabilities, system connectivity, business intelligence activity monitoring and management, rules and systems management.

4. Metadata management. This is becoming important as companies integrate data — for instance, customer and product data and warehouse data.

5. Virtualization. Virtualization technology is critical, but not just for consolidation; it also offers a way to mirror production systems for disaster recovery. Virtualization is now into its 2.0 version, as software vendors begin to ship their software in virtual machines with the operating system and needed middleware. This approach avoids the “deleterious effects of one piece of software on another.

6. Mashups. Mashup tools allow users to take things from multiple Web sites and combine them together to create a Web-centric composite application.

7. The Web platform. This is the model for services in the future. An example is the cloud computing announcement this week by Google Inc. and IBM, which are jointly offering a platform for use by universities for application development initiatives, including Web 2.0 projects.

8. Computing fabric. A server design that is still a work in progress, computing fabric involves treating memory, processors and I/O cards as a pooled resource instead of a fixed arrangement. Blade servers allow you to do some of this pooling with I/O.

9. Real World Web. This is the name of the computing experience made possible by ubiquitous access to networks of even-increasing bandwidth via mobile technologies. Thanks to the Real World Web, users can have ready access to all kinds of information, including travel information or the location of a jar of pickles in a grocery store.

10. Social software. Social software includes podcasts, blogs and wikis — anything that fosters the development of social networks.

Buku berikut hasil kompilasi penulisan Ilmiah Fitrah, Dian, Pamela, eviyanti, Satyani, mahasiswa Teknik Informatika, Universitas Gunadarma. Meskipun hanya berupa terjemahan user manual LUA, namun saya yakin bermanfaat untuk kita. Buku bisa di download disini (pdf file)

Pendahuluan

Saat ini, banyak bahasa pemrograman yang terfokus pada bagaimana caranya membantu anda menulis program-program dengan ratusan ribu baris. Untuk itu, mereka menawarkan anda paket-paket, namespaces, sistem tipe kompleks, ribuan konstruksi, dan halaman-halaman dokumentasi untuk dipelajari.

Namun tidak pada Lua. Justru, Lua mencoba membantu anda untuk memecahkan masalah dalam ratusan baris, bahkan lebih sedikit. Untuk mencapai tujuan ini, Lua mengandalkan sifat extensibility, seperti banyak bahasa lainnya. Tidak seperti hampir semua bahasa lainnya, bagaimanapun, Lua mudah dikembangkan tidak hanya dengan software khusus yang ditulis dengan Lua, tetapi juga dengan software yang ditulis dengan bahasa lain, seperti C dan C++.

Lua dirancang, sejak awal, untuk terintegrasi dengan perangkat lunak yang ditulis dengan C dan bahasa-bahasa konvensional lain. Dualitas bahasa ini membawa banyak manfaat. Lua merupakan bahasa yang sederhana dan mudah, sebagian karena Lua tidak mencoba untuk melakukan apa yang telah dapat dilakukan bahas C, seperti kinerja yang tipis, operasi low-level, atau penghubung dengan perangkat lunak pihak ketiga. Lua mengandalkan C untuk melakukan tugas tersebut. Apa Yang Lua tawarkan adalah apa yang tidak dapat dilakukan dengan baik pada C : suatu jarak yang baik dari perangkat keras, struktur-struktur dinamis, tanpa redudansi, pengecekan yang mudah dan debugging. Untuk itu, Lua mempunyai lingkungan yang aman, manajemen memori otomatis, dan fasilitas terbaik untuk menangani string dan data jenis lain dengan ukuran yang dinamis.

Lebih dari sekedar menjadi bahasa yang dapat diperluas, Lua juga merupakan bahasa perekat (glue language). Lua mendukung pendekatan berbasis komponen pada perkermbangan software, di mana kita membuat satu aplikasi dengan merekatkan komponen-komponen prioritas tinggi yang ada. Biasanya, komponen-komponen ini ditulis dalam susunan hipunan (compiled), bahasa yang statis, seperti C atau C++; Lua merupakan perekat yang kita gunakan untuk menyusun dan menghubungkan komponen-komponen itu.

Biasanya, komponen-komponen (object) ditunjukkan lebih kongkrit, konsep low-level (seperti widgets dan struktur data) yang bukan subjek pada banyak perubahan selama perkembangan program dan yang mengambil sebagian terbesar waktu CPU dari program akhir. Lua memberi bentuk akhir dari aplikasi, yang mungkin akan mengubah selama daur hidup produk. Bagaimanapun, tidak seperti teknologi glue lainnya. Oleh karena itu kita dapat menggunakan Lua tidak hanya untuk melekatkan komponen, tetapi juga untuk mengadaptasikan dan mengatur bentuk komponen itu, atau bahkan menciptakan seluruh komponen itu.

Tentu saja, Lua bukan satu-satunya bahasa penulisan (scripting language). Terdapat bahasa-bahasa lain yang dapat digunakan dengan tujuan yang hampir sama, seperti Perl, Tcl, Ruby, Forth, and Python. Keunggulan fasilitas-fasilitas berikut menjadikan Lua jauh berbeda dari bahasa-bahasa ini; meski bahasa-bahasa lain berbagi sebagian fasilitas berikut dengan Lua, tidak ada bahasa lain yang menawarkan profile serupa:

· Extensibility: Extensibility Lua sangat menarik perhatian sehingga banyak orang menganggap Lua bukan sebagai suatu bahasa, tetapi sebagai suatu perangkat untuk membangun bahasa-bahasa domain spesifik. Lua telah dirancang untuk diperluas/diaplikasikan, pada kode Lua dan kode eksternal C. Sebagai suatu bukti dari konsep, Lua menerapkan banyak kemampuan dasarnya melalui fungsi-fungsi eksternal. Hal ini sangat mudah untuk menghubungkan Lua dengan C/C++ dan bahasa-bahasa lain, seperti Fortran, Java, Smalltalk, Ada, bahkan dengan bahasa-bahasa penulisan yang lain.

· Simplicity / Sederhana : Lua adalah bahasa yang mudah dan sederhana. Lua mempunyai sedikit konsep (namun tangguh). Kesederhanaan ini membuat Lua mudah dipelajari dan memperbesar suatu implementasi yang sederhana. Distribusinya yang lengkap (source program, manual, biner-biner lebih untuk beberapa platform) sesuai dengan floopy disk.

· Efisiensi: Lua mempunyai implementasi yang efisien. Benchmark-benchmark yang mandiri menunjukkan Lua sebagai bahasa tercepat dalam dunia bahasa penulisan (interpreted).

· Portabilitas: Ketika kita berbicara tentang portabilitas, kita tidak berbicara tentang menjalankan Lua di platform Windows dan Unix. Kita berbicara tentang menjalankan Lua di semua platform yang sudah pernah kita dengar, seperti: NextStep, OS/2, PlayStation II (Sony), Mac OS-9 dan OS X, BeOS, MS-DOS, IBM, EPOC, PalmOS, MCF5206ELITE Evaluation Board, RISC OS, dan tentu saja semua jenis Unix dan Windows. Source program untuk masing-masing platform hampir sama. Lua tidak menggunakan kumpulan kondisi untuk menyesuaikan kodenya kepada mesin-mesin yang berbeda; sebagai gantinya, Lua mengikuti standar ANSI ( ISO) C. Dengan cara itu, biasanya anda tidak perlu menyesuaikan pada suatu lingkungan baru: Jika anda mempunyai satu compiler ANSI C, anda hanya harus meng-kompile Lua, out of box.

Bagian kehandalan Lua terletak pada pustakanya (library). Salah satu dari kekuatan utama Lua yaitu sifat ekstensibilitas pada tipe barunya dan fungsi-fungsinya. Banyak fitur yang berperan dalam kehandalan ini. Pengetikan dinamis mengizinkan tingkat polimorfisme. Manajemen memori otomatis menyederhanakan penghubungan, karena tidak perlu memutuskan siapa yang bertanggung jawab atas alokasi dan dealokasi memori, atau bagaimana caranya menangani overflows. Fungsi-fungsi penugasan yang tinggi (Higher-order) dan fungsi-fungsi tanpa nama mengizinkan suatu prioritas tinggi parametrisasi, pembuatan fungsi-fungsi lebih serbaguna. Lua hadir dengan suatu set kecil pustaka standar. Saat menginstall Lua pada lingkungan dengan kapasitas terbatas, seperti processor, mungkin harus lebih hati-hati untuk memilih pustaka yang dibutuhkan. Lebih dari itu, jika keterbatasan sangan besar, dengan mudah dapat masuk pada pustaka source program dan memilih satu-persatu fungsi-fungsi mana saja yang harus tetap disimpan. Ingat, bagaimanapun, Lua lebih sederhana (bahkan dengan semua standar pustaka) dan dalam kebanyakan sistim anda dapat menggunakan keseluruhan paket tanpa kawatir.
