ISMS is a framework of policies, procedures, guidelines and associated resources to establish, implement, operate, monitor, review, maintain and improve information security for all types of organisation. ISMS is defined in the family of standard and guidelines published jointly by the International Standardization Organisation (ISO) and the International Electrotechnical Commission (IEC) , ISO/IEC 27000 . This standard defines the requirement for an ISMS establishes the basis for certification of an ISMS. The standards explain the overall plan-do-check-act (PDCA) approach provide detail guidance for it implantation.

ISO/IEC 27000:2016, latest published: 2016-02-15, the overview of information security management systems, and terms and definitions commonly used in the ISMS family of standards. This International Standard is applicable to all types and sizes of organization (e.g. commercial enterprises, government agencies, not-for-profit organizations).

ISO is an independent, non-governmental international organization with a membership of 161 national standards bodies. Through its members, it brings together experts to share knowledge and develop voluntary, consensus-based, market relevant International Standards that support innovation and provide solutions to global challenges.

The International Electrotechnical Commission (IEC) is a not-for-profit, non-governmental organization, founded in 1906. The IEC's members are National Committees, and they appoint experts and delegates coming from industry, government bodies, associations and academia to participate in the technical and conformity assessment work of the IEC. The International Electrotechnical Commission is the leading global organization that publishes consensus-based International Standards and manages conformity assessment systems for electric and electronic products, systems and services, collectively known as electrotechnology. IEC publications serve as a basis for national standardization and as references when drafting international tenders and contracts. Reference: http://www.iec.ch/about/

It’s the most accepted technique of media rotation. In this method, illustrate as below:   - Daily backup (son) are made over the course of a week.   - The earlier daily backup media are then rotated to reuse as backup media for the sequence weeks   - The final backup taken during the week become the backup of that week (father)   - The earlier weekly backup media are then rotated to reuse as backup media for the sequence months   - At the end of the month, the final weekly backup is retained as the backup for that month (grandfather) Given example: Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7 Week 1 Tape 1 (son) Tape 2 (son) Tape 3 (son) Tape 4 (son) Tape 5 (son) Tape 6 (son) Tape 7 (father) Week 2 Tape 1 (son) Tape 2 (son) Tape 3 (son) Tape 4 (son) Tape 5 (son) Tape 6 (son) Tape 8 (fathe

There are 3 backup schemes which each of them has its own advantages and disadvantages. 1. Full backup This scheme type copies all file or folders to create a backup set. Advantages: - It has a unique repository in case of restoration. Disadvantages: - It requires more time and media capacity 2. Incremental backup This backup copies the files or folder that changed or are new since the last incremental or full backup. If you have a full backup on day 1, your incremental backup on day 2 will copies only the changes made from day 1 to day 2. On day 3, it will copy the changes made from day 2 to day 3. Advantages: - It’s faster backup method and requires less media capacity Disadvantages: - It requires more time for restoration, all backup sets need to be restored since a full backup. Given example: full plus incremental backup + Day 1: full backup + Day 2 to 7: incremental backup    -> Day 1: new files: 1, 2, 3 & 4    -> Day 2: file 1 cha

Windows command prompt is is an entry point for typing computer commands in the Command Prompt window. By typing commands at the command prompt, you can perform tasks on your computer without using the Windows graphical interface. How to run the command prompt: -> "Start" -> "All Programs" -> "Accessories" -> "Command Prompt" OR -> "Start" -> search "command prompt" or "cmd"

Easy tip to get detailed configuration information about a computer and its operating system is just a few simply steps.

Solaris (UNIX based) Solaris, the UNIX-based operating system developed by SUN Microsystem, was born in 1987. AT&T and SUN Microsystem tried to combine the leading Unix versions (BSD, XENIX, and System V) into one operating system. In 1991, SUN Microsystem replaced it's existing Unix operating system (SunOS 4) with one based on SVR4, called Solaris 2. Contained with many new advances, including use of the Open Network Computing (ONC) functionality, NIS+ and OpenWindows graphical user interface, Solaris 2 was specially designed for symmetric multiprocessing. And now, for more than twenty-years, numerous versions of Solaris has been released with great innovations to adapt the changing of the computer environment, trying to anticipate where the computer world is going. Innovations that Solaris OS has made will takes pages to be described. I’ll show you some of the most important milestones: 1. 1996 – Solaris 2.5.1 – NFSv3 file system and NFS/TCP, CDE (Common Desktop Envir

AS/400 (IBM's product) On June 21, 1988, IBM introduced the Application System/400 (AS/400), a new family of easy-to-use computers designed for small and intermediate-sized companies. As part of the worldwide introduction, IBM and IBM Business Partners worldwide rolled out more than 1,000 software packages in the biggest simultaneous applications announcement in computer history. Seen here are the AS/400 B-series models (IBM 9404 and IBM 9406), which illustrate the varying sizes and configurations available in the initial offering. The AS/400 quickly became one of the world's most popular business computing systems. By 1997, IBM had shipped nearly a half-million AS/400s. The 400,000th AS/400 was presented on October 9, 1996, in Rochester, Minn., to Greg LeMond, the three-time winner of the Tour de France bicycle race and a small business entrepreneur. The AS/400 family was succeeded in 2000 by the IBM eServer iSeries -- high-performance, integrated business servers for mid-mark
