Data & Computer Recovery Guidelines
Data & Computer Recovery Guidelines Data & Computer Recovery Guidelines This document contains general guidelines for restoring computer operating following certain types of disasters. It should be noted these guidelines will not fit every type of disaster or every organization and that you may need to seek outside help to recover and restore your operations. This document is divided into five parts. The first part provides general guidelines which are independent of the type of disaster, the next three sections deal with issues surrounding specific disaster types (flood/water damage, power surge, and physical damage). The final section deals with general recommendations to prepare for the next disaster. General Guidelines 2. Your first step is to restore the computing equipment. These are general guidelines for recovering after any type If you do try to power on the existing equipment, it of disaster or computer failure. If you have a disaster is best to remove the hard drive(s) first to make sure recovery plan, then you should be prepared; however, the system will power on. Once you have determined there may be things that were not covered to help the system powers on, you can reinstall the hard drive you recover. This section is divided into two sections and power the system back on. Hopefully, everything (computer system recovery, data recovery) works at that point. Note: this should not be tried in the case of a water or extreme heat damage. Computer System Recovery 3. If the computer will not power on then you can either The first step is to get your physical computer systems try to fix the computer or in many cases it is easier, running again. -
Data Remanence in Non-Volatile Semiconductor Memory (Part I)
Data remanence in non-volatile semiconductor memory (Part I) Security Group Sergei Skorobogatov Web: www.cl.cam.ac.uk/~sps32/ Email: [email protected] Introduction Data remanence is the residual physical representation of data that has UV EPROM EEPROM Flash EEPROM been erased or overwritten. In non-volatile programmable devices, such as UV EPROM, EEPROM or Flash, bits are stored as charge in the floating gate of a transistor. After each erase operation, some of this charge remains. It shifts the threshold voltage (VTH) of the transistor which can be detected by the sense amplifier while reading data. Microcontrollers use a ‘protection fuse’ bit that restricts unauthorized access to on-chip memory if activated. Very often, this fuse is embedded in the main memory array. In this case, it is erased simultaneously with the memory. Better protection can be achieved if the fuse is located close to the memory but has a separate control circuit. This allows it to be permanently monitored as well as hardware protected from being erased too early, thus making sure that by the time the fuse is reset no data is left inside the memory. In some smartcards and microcontrollers, a password-protected boot- Structure, cross-section and operation modes for different memory types loader restricts firmware updates and data access to authorized users only. Usually, the on-chip operating system erases both code and data How much residual charge is left inside the memory cells memory before uploading new code, thus preventing any new after a standard erase operation? Is it possible to recover data application from accessing previously stored secrets. -

EEPROM Emulation
...the world's most energy friendly microcontrollers EEPROM Emulation AN0019 - Application Note Introduction This application note demonstrates a way to use the flash memory of the EFM32 to emulate single variable rewritable EEPROM memory through software. The example API provided enables reading and writing of single variables to non-volatile flash memory. The erase-rewrite algorithm distributes page erases and thereby doing wear leveling. This application note includes: • This PDF document • Source files (zip) • Example C-code • Multiple IDE projects 2013-09-16 - an0019_Rev1.09 1 www.silabs.com ...the world's most energy friendly microcontrollers 1 General Theory 1.1 EEPROM and Flash Based Memory EEPROM stands for Electrically Erasable Programmable Read-Only Memory and is a type of non- volatile memory that is byte erasable and therefore often used to store small amounts of data that must be saved when power is removed. The EFM32 microcontrollers do not include an embedded EEPROM module for byte erasable non-volatile storage, but all EFM32s do provide flash memory for non-volatile data storage. The main difference between flash memory and EEPROM is the erasable unit size. Flash memory is block-erasable which means that bytes cannot be erased individually, instead a block consisting of several bytes need to be erased at the same time. Through software however, it is possible to emulate individually erasable rewritable byte memory using block-erasable flash memory. To provide EEPROM functionality for the EFM32s in an application, there are at least two options available. The first one is to include an external EEPROM module when designing the hardware layout of the application. -
PROTECTING DATA from RANSOMWARE and OTHER DATA LOSS EVENTS a Guide for Managed Service Providers to Conduct, Maintain and Test Backup Files
PROTECTING DATA FROM RANSOMWARE AND OTHER DATA LOSS EVENTS A Guide for Managed Service Providers to Conduct, Maintain and Test Backup Files OVERVIEW The National Cybersecurity Center of Excellence (NCCoE) at the National Institute of Standards and Technology (NIST) developed this publication to help managed service providers (MSPs) improve their cybersecurity and the cybersecurity of their customers. MSPs have become an attractive target for cyber criminals. When an MSP is vulnerable its customers are vulnerable as well. Often, attacks take the form of ransomware. Data loss incidents—whether a ransomware attack, hardware failure, or accidental or intentional data destruction—can have catastrophic effects on MSPs and their customers. This document provides recommend- ations to help MSPs conduct, maintain, and test backup files in order to reduce the impact of these data loss incidents. A backup file is a copy of files and programs made to facilitate recovery. The recommendations support practical, effective, and efficient back-up plans that address the NIST Cybersecurity Framework Subcategory PR.IP-4: Backups of information are conducted, maintained, and tested. An organization does not need to adopt all of the recommendations, only those applicable to its unique needs. This document provides a broad set of recommendations to help an MSP determine: • items to consider when planning backups and buying a backup service/product • issues to consider to maximize the chance that the backup files are useful and available when needed • issues to consider regarding business disaster recovery CHALLENGE APPROACH Backup systems implemented and not tested or NIST Interagency Report 7621 Rev. 1, Small Business planned increase operational risk for MSPs. -
