For transparent encryption, of lesson, is full of. In other words, the petition software to generate temporary files should too be dense state.
numerous applications in the edit data files, temporary files are generated. The most well understood is that MS Word doc file editing,
GHD IV Salon Straighteners, will appear in the same catalogue as These temporary files in the corresponding data file is properly closed, will be deleted. As these temporary files are cached confidential commerce data, and accordingly the protection of these temporary files are extremely important.
suppliers in a test this period, with particular care. Some brands of encryption system, in mandate to give their convenience, to give up on the intermediate file is encrypted. For example, a practiced of the industry's contractors have accepted such an approach: ① the use of intercept procedures Hook technology file open action; ② to open the decrypted file to a hidden file operations on the data pointer in the This design allows the user appears to be competent to open the secret text editor, edit, save, or get the ciphertext. But in truth the real editing application software thing is a non-encrypted plaintext files. This approach, in principle it is also feasible But, after all, Murder, that If the credit node User knows this
transparent encryption should be only for data files, operating system files and application software files naturally can not be encrypted. Moreover, assorted users, even users with a different department, files of data to be encrypted are not the same. Such as product design department should be encrypted on the product drawings, and the Photoshop *. psd files you do not need encryption. However, the planning department for message may be equitable the opposite, their mental outcome of inspired duplicate, and copy *. psd file is fair to load the. In short,
GHD Dark Styler Straighteners, *. psd file in the technology sector is not perceptive, and in the publicity department is sensitive planning. Therefore, the procedure how to resolve whether a file should be encrypted, yet also a transparent encryption system is extremely important to examine arrows. This problem can also put it distinct way: How should the administrator to set encryption rules.
face this problem, encryption vendors, there are three options.
First, specify the path,
GHD Green Styler Straighteners, that is to save the file in the specified path be encrypted. System administrators can specify for each node one or more credit If users save the file to this path, then the file will be encrypted. As the transparent encryption function is Manufacturers in response to this problem, usually to invest such a solution: ① All applications will be fully installed in C steer, then make a mirror on the C drive, the other disk (both plausible or physical disk) only allows storing data files; ② will in increase to all the letter drive other than C are set to automatically reinstate the C drive (much favor Internet cafes and some corporations in use of the reduction technology).
Second, specify the application, that is generated along the specified application documents be encrypted. System administrators can specify for each node one or more credit If the average user to use these applications to save files secret, then the file will be encrypted. For example, the example cited earlier, the system administrator can set the AutoCAD application for the technology sector, classified, will set the planning department Photoshop classified applications.
Third, clarify the suffix, namely namely apt retention the file at all times the specified suffix, the file ambition be encrypted. System administrators tin clarify as each knot an alternatively more honor If the average user will save the data file for this enhancement, the file will be encrypted. Continue bearing above the cases, the system administrator can *. dwg and *. psd were set for the technical division and maneuvering division of the
these three ways, each with advantages and disadvantages.
1st approach has the advantage of easy to implement, and does not concern what application software. But the disadvantages are also obvious. Mainly It’s about time: ① routine IT livelihood work to build a excellent deal of inconvenience: the signature anti-virus software upgrades, installing new applications, etc., will restore the C drive with the restore, unless you first clear the C disk protection, upgrade or setup later the end of revitalization protection; ② has obvious security flaws: the average user can first save the file to the C drive, then shut down Windows, and even forced a power outage, production the reduction of the C drive machinery has as yet had time to activity will drive away the role of demolition, which will state the data file that away. Because obviously more damage than good, so this approach is only accustom by a few manufacturers; ③ does not distinguish itself from the file, will produce over encrypted (so-called over-encryption is also encrypted should not be encrypted,
second approach has the advantage of very agreeable close to the user, is persistent with the user's way of preoccupied, for users are most cared almost,
GHD Leopard Grain Straighteners, This user-friendly way to amplify and preserve rules. In general, the use of encryption systems in this way will be limited: only the application software ahead they can open the secret cipher, non-classified applications are no allowed to open the ciphertext. (This limitation is cozy to understand: If the non-classified applications are able to open the ciphertext, it then save the file, close the text becomes clear.) This brings the way of a drawback, which may will lead to over-encryption. For example, the software manufacture is very obvious. They are commonly the source code of the program to encrypt, that is *. c, *. h files such as source code is usually ciphertext. Compiler absences to read the source code of these secret state documents, rational to say that the compiler should be classified programs. But by the same compiler also generates the target file, the target file is not should be encrypted. A alike rebuttal exists in assorted other industries. For example, in manufacturing manufacture machining programming software, on the one hand to read the secret state dwg file,
GHD Straighteners NZ, the other state to generate machining code that files; in the construction industry in the structural analysis software, on the one hand to read dwg file state secret, the other states to generate report files, etc. tomorrow.
third reach has the advantage is relatively close to the user, more in line with the user's way of musing. The drawback is complicated to specify through the exhaustive reach to always the Generally recommended that you select a Some brands of perspicuous encryption system, when using the second method and third usage,
GHD Rare Styler Straighteners, and primarily for the shortcomings of the second approach has taken some corrective fathom (for example, can be set for a secluded program exception suffix). For users, this devise is the maximum attractive.
