USB Flash Drive Security
Secure USB flash drives protect the data stored on them from access by unauthorized users. USB flash drive products have been on the market since 2000, and their use is increasing exponentially. As businesses have increased demand for these drives, manufacturers are producing faster devices with greater Computer data storage, data storage capacities. An increasing number of portable devices are used in business and decreased numbers for consumers, such as laptops, notebooks, personal digital assistants (PDA), smartphones, USB flash drives and other mobile devices. Companies in particular are at risk when sensitive data are stored on unsecured USB flash drives by employees who use the devices to transport data outside the office. The consequences of losing drives loaded with such information can be significant, including the loss of customer data, financial information, business plans and other confidential information, with the associated risk of reputation damage.

USB Flash Drive
A flash drive (also thumb drive, memory stick, and pen drive/pendrive) is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc, and usually weighs less than . Since first offered for sale in late 2000, the storage capacities of USB drives range from 8 megabytes to 256 gigabytes (GB), 512 GB and 1 terabyte (TB). As of 2024, 4 TB flash drives were the largest currently in production. Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and are thought to physically last between 10 and 100 years under normal circumstances (Digital permanence, shelf storage time). Common uses of USB flash drives are for storage, supplementary data backup, back-ups, and transferring of computer files. Compared with floppy disks or Compact disc, CDs, they are smaller, faster, have significantly more capacity, and are more durable due to ...

BitLocker
BitLocker is a full volume encryption feature included with Microsoft Windows versions starting with Windows Vista. It is designed to protect data by providing encryption for entire volumes. By default, it uses the Advanced Encryption Standard (AES) algorithm in cipher block chaining (CBC) or " xor–encrypt–xor (XEX) -based tweaked codebook mode with ciphertext stealing" (XTS) mode with a 128- bit or 256-bit key. CBC is not used over the whole disk; it is applied to each individual sector. History BitLocker originated as a part of Microsoft's Next-Generation Secure Computing Base architecture in 2004 as a feature tentatively codenamed "Cornerstone" and was designed to protect information on devices, particularly if a device was lost or stolen. Another feature, titled "Code Integrity Rooting", was designed to validate the integrity of Microsoft Windows boot and system files. When used in conjunction with a compatible Trusted Platform Module (TPM), BitLocker can validate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Remanence
Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously written data to be recovered. Data remanence may make inadvertent disclosure of sensitive information possible should the storage media be released into an uncontrolled environment (''e.g.'', thrown in the bin (trash) or lost). Various techniques have been developed to counter data remanence. These techniques are classified as clearing, purging/sanitizing, or destruction. Specific methods include overwriting, degaussing, encryption, and media destruction. Effective application of countermeasures can be complicated by several factors, including media that are inaccessible, media that c ...

Cruzer Enterprise
The SanDisk Cruzer Enterprise was an encrypted USB flash drive. This secure USB drive imposed a mandatory access control on all files, storing them in a hardware-encrypted, password-protected partition. The Cruzer Enterprise is designed to protect information on company-issued USB flash drives. Central Management and Control (CMC) server software centrally managed the drive, enabling password administration, data backup, and termination if the drive is lost or stolen. It was released around 2008. The Cruzer Enterprise supported Microsoft Windows 2000 SP4, Windows XP SP1, Windows Server 2003, Windows Vista, and Apple OS X 10.4 and 10.5. It was discontinued in November 2010. The SanDisk Cruzer Enterprise competed with other secure USB drives, including IronKey, Kingston, and Verbatim, and also disk encryption software such as FreeOTFE and TrueCrypt.

Health Insurance Portability And Accountability Act
The Health Insurance Portability and Accountability Act of 1996 (HIPAA or the Ted Kennedy, Kennedy–Nancy Kassebaum, Kassebaum Act) is a United States Act of Congress enacted by the 104th United States Congress and signed into law by President Bill Clinton on August 21, 1996. It aimed to alter the transfer of healthcare information, stipulated the guidelines by which personally identifiable information maintained by the healthcare and healthcare insurance industries should be protected from fraud and theft, and addressed some limitations on Health insurance in the United States, healthcare insurance coverage. It generally prohibits Health professional, healthcare providers and businesses called covered entities from disclosing protected information to anyone other than a patient and the patient's authorized representatives without their consent. The bill does not restrict patients from receiving information about themselves (with limited exceptions). Furthermore, it does not proh ...

Software As A Service
Software as a service (SaaS ) is a cloud computing service model where the provider offers use of application software to a client and manages all needed physical and software resources. SaaS is usually accessed via a web application. Unlike other software delivery models, it separates "the possession and ownership of software from its use". SaaS use began around 2000, and by 2023 was the main form of software application deployment. Unlike most self-hosted software products, only one version of the software exists and only one operating system and configuration is supported. SaaS products typically run on rented infrastructure as a service (IaaS) or platform as a service (PaaS) systems including hardware and sometimes operating systems and middleware, to accommodate rapid increases in usage while providing instant and continuous availability to customers. SaaS customers have the abstraction of limitless computing resources, while economy of scale drives down the cost. Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Boot Attack
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine. Typically, cold boot attacks are used for retrieving encryption keys from a running operating system for malicious or criminal investigative reasons. The attack relies on the data remanence property of DRAM and SRAM to retrieve memory contents that remain readable in the seconds to minutes following a power switch-off. An attacker with physical access to a running computer typically executes a cold boot attack by cold-booting the machine and booting a lightweight operating system from a removable disk to dump the contents of pre-boot physical memory to a file. An attacker is then free to analyze the data dumped from memory to find sensitive data, such as the keys, using various forms ...

Disk Utility
A disk utility is a utility software, utility program that allows a user to perform various functions on a computer disk, such as disk partitioning and logical volume management, as well as multiple smaller tasks such as changing drive letters and other mount points, renaming volumes, disk checking, and disk formatting, which are otherwise handled separately by multiple other built-in command (computing), commands. Each operating system (OS) has its own basic disk utility, and there are also separate programs which can recognize and adjust the different filesystems of multiple OSes. Types of disk utilities include disk checkers, disk cleaners and disk space analyzers Disk cleaners Disk cleaners are computer programs that find and delete potentially unnecessary or potentially unwanted files from a computer. The purpose of such deletion may be to free up disk space, to eliminate clutter or to protect privacy. Disk space consuming unnecessary files include temporary files, trash ( ...
