  Control-  ISO 27001 Annex : A.17.1.3 Verify, Review and Evaluate Information Security Continuity In order to ensure accurate and productive to adverse circumstances, the company must review on-going controls on safety information defined and enforced at regular intervals. Implementation Guidance-  Changes in organizational, technological, administrative and procedures, whether operational or framework, will lead to changes in the criteria for the continuity of  information security . In such cases, the continuity of information security processes, procedures and controls against these changed requirements should be reviewed. “It is far better to foresee without certainty than not to foresee at all” – Henri Poincare Organizations will track the consistency of their management of information security by: Exercise and test the reliability of systems, procedures, and controls for the protection of information in compliance with objectives of information continuity; Exe...

  Hard Disk Interfaces in this the hard disk drive connects to the PC using an interface. There are various types of interfaces: IDE, SATA, Fiber Channel, SCSI, etc. 1. ATA DATA (IDE/EIDE) IDE (Integrated Drive Electronics) is a standard electronic interface used between a computer motherboard’s data paths or bus and the computer’s disk storage devices, such as hard drives and CD-ROM/DVD drives. The IBM PC Industry Standard Architecture (ISA) 16-bit bus standard is base for the IDE interface, which offers connectivity in computers that use other bus standards. ATA (Advanced Technology Attachment) is the official American National Standards Institute’s (ANSI) name of Integrated Drive Electronics (IDE). 2. Parallel ATA: PATA, based on parallel signaling technology, offers a controller on the disk drive itself and thereby eliminates the need for a separate adaptor card. Parallel ATA standards only allow cable lengths up to 46 centimeters (18 inches). Features  of PATA: Relatively...

   In this article explain Logical & Physical Structure of a Hard Disk there components uses. Physical Structure of a Hard Disk The main components of hard disk drive are: Platters:  These are disk like structures present on the hard disk, stacked one above the other and store the data Head:   It is a device present on the arm of the hard drive that reads or writes data on the magnetic platters, mounted on the surface of the drive Spindle:  It is the spinning shaft on which holds the platters in a fixed position such that it is feasible for the read/write arms to get the data on the disks Actuator:  It is a device, consisting of the read-write head that moves over the hard disk con to save or retrieve information Cylinder These are the circular tracks present on the platters of the disk drive at equal distances from the center Related Product :  Computer Hacking Forensic Investigator | CHFI Physical Structure of a Hard Disk (Cont’d) A hard disk con...

In this article explain Discribe the different types of Disk and there characterstics & uses. Disk Drive is a digital data storage device that uses different storage mechanisms such as mechanical, electronic, magnetic, and optical to store the data. It is addressable and rewritable to support changes and modification of data. Depending on the type of media and mechanism of reading and writing the data, the different types of disk drives are as follows: Magnetic Storage Devices:   Magnetic storage devices store data using magnets to read and write the data by manipulating magnetic fields on the storage medium. These are mechanical devices with components moving to store or read the data. Few other examples include floppy disks, magnetic tapes, etc. In these types of hard disks, the disks inside the media rotate at high speed and heads in the disk drive read and write the data. Optical Storage Devices:  Optical storage devices are electronic storage media that store and read...

ISO 27001 Annex : A.17 Information Security Aspects of Business Continuity Management in this article explain Information Security Continuity, Planning Information Security Continuity and Implementing Information Security Continuity this contols. A.17.1 Information Security Continuity Its objective is the continuity of  information security  should be integrated into the business continuity management processes of the organization. A17.1.1 Planning Information Security Continuity Control –  In adverse circumstances, e.g. during a crisis or a catastrophe, the company will determine the information security standards and consistency of information security management. Implementation Guidance-   An organization should assess whether the continuity of security is captured in the management process of business continuity or in the disaster recovery process. In business continuity preparation and disaster recuperation, information security standards will be determined. The...
