On a hard drive, the sectors are always the same size of 512 bytes. Depending on the file system used to format the hard drive, the sectors will be clumped together into clusters. For instance, in Windows NTFS, the standard size for a cluster is four sectors. This means that a cluster is (4×1024=4096) bytes.
Correspondingly, what happens when you copy an encrypted file from an EFS enabled NTFS disk to a non EFS disk or folder?
The file is unencrypted automatically. Only the owner of the file can continue to access it. The file is unencrypted automatically.
Likewise, what's a virtual cluster number? Any cluster in a file has a virtual cluster number (VCN), which is its relative offset from the beginning of the file. A logical cluster number (LCN) describes the offset of a cluster from some arbitrary point within the volume.
Beside above, why was EFI Bootware developed quizlet?
EFI boot firmware was developed to provide better protection against malware then BIOS does. Device drivers contain what kind of information? Device drivers contain instructions for the OS on how to interact with hardware devices.
What does CHS mean quizlet?
Cylinder, head and starter. 3. Zone bit recording is how disk manufacturers ensure that a platter's outer tracks store as much data as possible.
Where are EFS certificates stored?
Basically, the way it works is that when a user requests that a file or folder be encrypted, an EFS certificate is generated for the user and its private key is stored in the user's profile. The public key is stored with the files created by that user, and only that user can decrypt the file.What is the most difficult part of designing a cryptosystem?
Key Exchange and Management Key management deals with the secure generation, verification, exchange, storage, and destruction of keys. It is extremely important to have secure methods of key management. Key exchange and management are often considered the most difficult part of designing a cryptosystem.How do you decrypt a file?
To decrypt a file or folder:- From the Start menu, select Programs or All Programs, then Accessories, and then Windows Explorer.
- Right-click the file or folder you want to decrypt, and then click Properties.
- On the General tab, click Advanced.
- Clear the Encrypt contents to secure data checkbox, and then click OK.
What happens when a file is encrypted?
When files are encrypted, they're scrambled to the point that they're unusable unless they can be decrypted, which is usually only possible with specific software and knowledge of the same password used for encryption. You might encrypt your files if you keep sensitive information that you need to keep private.What is basic EFS certificate?
The EFS (Encrypting File System) always attempts to enroll the Basic EFS template. When requesting a certificate on first use, EFS requests the Basic EFS template, or it uses auto-enrollment. When no certificates exist on the client computer, the version 1 template of the Basic EFS is used.How does EFS encryption work?
EFS works by encrypting a file with a bulk symmetric key, also known as the File Encryption Key, or FEK. It uses a symmetric encryption algorithm because it takes less time to encrypt and decrypt large amounts of data than if an asymmetric key cipher is used.How are files encrypted?
Data, or plaintext, is encrypted with an encryption algorithm and an encryption key. The process results in ciphertext, which only can be viewed in its original form if it is decrypted with the correct key. Symmetric-key ciphers use the same secret key for encrypting and decrypting a message or file.What are the three rules for a forensic hash?
What are the three rules for a forensic hash? It can't be predicted, no two files can have the same hash value, and if the file changes, the hash value changes.What methods do steganography programs use to hide data in graphics files?
Steganography program hides the data in the files by insertion by using host file. The file that is to be hidden is placed in the host file and when someone see the host file the hidden content is not visible without having the look at the data structure.What is a bit stream image quizlet?
bit-stream copy. A bit-by-bit duplicate of data on the original storage medium. This process is usually called "acquiring an image" or "making an image." bit-stream image. The file where the bit-stream copy is stored; usually referred to as an "image," "image save," or "image file."What are the major improvements in the Linux ext4 file system?
What are the major improvements in the Linux Ext4 file system? Support for partitions larger than 16TB, improved management of large files, and offered a more flexible approach to adding file system features.What is the purpose of the reconstruction function in a forensics investigation?
What is the purpose of the reconstruction function in a forensics investigation? 1. Re-create a suspect's drive to show what happened during a crime or incident.What are some ways to determine the resources needed for an investigation?
