• Encryption and Protection of SQLite database - App of signature with the Signature of Blackberry tool

  Hello

  I am trying to encrypt and protect my SQLite database. To do this, I have generated a pair of public/private key using the administration Blackberry signature tool. Then, I added the .key file to my project and written the code for encryption and data protection. Then, I signed the app with Blackberry signing authority tool such as mentioned in the documentation. It was duly signed. But my application does not work on the device. It shows that my application tries to access a secure API which means that it is not properly signed.

  What could be the problem?

  And also I want to know what is the difference between the signing of the "Tool of signed" app within the eclipse and sign the application with "Blackberry signing authority tool '?

  I sign my application with eclipse itself "tool of signed" before adding the public .key file and it worked very well.

  Please suggest.

  Thank you.

  You must sign with both.

• Universal Clipboard is encrypted and how the data is stored in iCloud

  Hello

  You need a deep understanding of the works of the new, universal Clipboard feature safety? The feature is nice, but do you copy your password by company store system administrator password... This password is moving all over the world and also through Apple servers... Don't make me happy.

  Who can guarantee that the communication is encrypted and the data stored in iCloud are not used for other purpose?

  Thanks and greetings

  Security and privacy - Apple Support Overview iCloud

  Although not listed here, all data transmitted to the Apple servers is encrypted in transit and on the server.

  I can't offer any advice on the question of whether your transmissions could be intercepted and decoded.

  They say they also unequivocally that they never provide encryption keys to any third party. Which has been further strengthened with their recent dealings with the FBI.

  You'll have to decide for yourself if you agree with what Apple says.

• Transparent data encryption and Performance

  We started a project to encrypt our SAP database using the transparent data encryption.  The project is currently mandated by corporate policy, so there is not much choice involved.  The indications are:

  The server O/s: HP - UX 11.31

  CPU: HP Itanium

  Oracle Version: 11.2.0.3 (64-bit)

  DB Dimensions: Approx. 5 TB

  Core SAP: 7.x

  Our leadership is very concerned about the impact on performance.  If you have encrypted your database, SAP or not, I am very interested in hearing if you the performance of your server data after encryption.  Good news, bad news, either.

  TIA,

  Mike

  Dear Mike,

  I can give you a few comments based on direct experience, since we recently migrated from an unencrypted Oracle (11g Enterprise Edition Release 11.2.0.3.0) server to a new server with encryption TDE (same version db).

  Our application is a warehouse of data with massive volumes of data (terabytes) and a few very large tables.

  After having migrated to the new server, which was much more powerful than the former, we were surprised to discover that the performance was much worse (about two times slower, on average, measured on our typical user queries).

  A study on the causes of degradation in performance shows that transparent data encryption are the source of the problem, causing a saturation of the individual CPU (do not look at the aggregate average load on the CPU, which is misleading).

  Basically, we have been deceived by the official Oracle documentation that estimates the impact on the performance of the transparent data encryption in the order of 5 to 8%. Further investigation showed that this low impact may be true of operations that involve a small amount of data. With the full picture of the analyses on large tables however, the truth is that the performance may be (5 - 10 times) slower order that without transparent encryption of data.

  If you want more information, take a look at this excellent article (in two parts):

• How do I encrypt a data file so that only I can retrieve the Info?

  How do I encrypt a data file so that it cannot be read without permission?

  I have a request where the client shouldn't have access to the data that I need to save for troubleshooting purposes.  (there are trade secrets, I want to protect)  My plan is to save a datalog (currently I produce a Spreadsheet tabs-delimited format) whenever the device is running and hide the files where they will not likely be found.  But some sort of encryption or everything at least password protection would be better.

  I never tried to do this before, but thought it would be pretty easy.  Maybe I'm looking all just not in the right places.

  Thank you

  Well, you could look in something like DES, Triple, ESA, etc.  It has libries lying since these writings in LabVIEW.  I'm not sure about the cost.

  If you want a very simple way to protect your data, just reverse all or part of the bits in each byte of the file.  It's super simple and turns a nice ASCII text file noise when read from a text file.

• Making sure that I understand Appassure encryption for data replication

  Hi all

  I hope I can get clarification on encryption in Appassure.

  We have agents in remote offices, carrots on-site backup, then the carrots of off-site replication to our central office. These replication tasks travel via setup of vpn in each office to the central office.

  We have several smaller offices and offices micro we don't have dedicated vpn and would prefer to keep it that way. Of course, be sure that the data circulating on the internet is encrypted. My understanding is given in Appassure is encrypted on the kernel and therefore when it is travelling off-site it remains encrypted.

  So if we replicated offsite to a remote database to our central office without a vpn data are secure and encrypted completely during the trip. Is this the case?

  In addition, my understanding is the data travelling agent to the local base are not encrypted and moves on the local network in "clear text", for lack of a better description. Is this the case?

  Thank you for any information that you can provide

  All data traveling between the agent and the kernel and between two nuclei is encrypted using SSL/TLS.  It is a secure connection.  If you use an encryption key, the data is encrypted more away when it gets to the heart the backup and is then stored encrypted.  From that point on the data is encrypted with the encryption key and encrypted as part of the transfer of data from one base to another.  Double is encrypted.  Your data is completely safe while flight using an encryption key or not.  The reason to use an encryption key is to ensure that your data is encrypted at rest.

• How can I get voice and data to work with the ASA 5505?

  Here's the issue I'm having.   Can I get a Cisco 7940 to work behind one site to another configured ASA 5505 and I can also get data to work behind it.  However, when I try to create a separate Vlan for voice and data, it does not work.  Our voice VLANs on our remote sites are 172.30 and data are 172.31, when I put the inside interface with 172.31 data will work and when I on it 172.30 voice will work.  I upgraded to a security more license and tried vlan3 created as voice.  I have the data to the top and work but I can't get vlan3 to work.   Any help would be greatly appreciated.  Thank you

  Peter,

  Note that access list names are case-sensitive, so you've actually done something different from what I proposed.

  Please do:

  no nat (Corp_Voice) 0-list of access vpn

  No list of vpn access extended permitted ip TESTvpn 255.255.255.0 everything
  IP 172.30.155.0 255.255.255.0 extended vpn access do not allow any list all

  extended VPN ip 172.30.155.0 access list allow 255.255.255.0 any

  NAT (Corp_Voice) 0-list of access VPN

  In the case where you did deliberately, for example to separate the 2 acl: note that acl VPN (upper case) is also used in the encryption card, where you cannot add a second LCD.

  So if you want to separate you, you will need 3 access lists:

  list of access data-vpn ip TESTvpn 255.255.255.0 allow one

  voice-vpn ip 172.30.155.0 access list allow 255.255.255.0 any

  access-list all - vpn ip TESTvpn 255.255.255.0 allow one

  access-list all - vpn ip 172.30.155.0 allow 255.255.255.0 any

  NAT (inside) 0-list of access vpn data

  NAT (Corp_Voice) - access list 0 voice-vpn

  outside_map 1 match address all vpn crypto card

  Don't know if this was also clearly to my previous message, I recommend you to replace the "all" (in each of the ACL lines) to something more specific (i.e. a remote network, or group of objects that contain the remote networks).

• PGP Whole Disk Encryption and Boot Camp Partition

  I use the PGP 10.0 Beta for the last two weeks (it is now been shipped and is the current version), and one of the new features is Whole Disk Encryption on Boot Camp partitions. It works fine - except for the fact that VMWare Fusion 3.0.1 can not load the Boot Camp partition is encrypted (it starts initially, but does not advance beyond what I suppose is the PGP bootloader).

  I know that I can create a virtual machine and run Windows to work around the problem - I'm just curious to know if this is something that VMWare are willing to study and operate now PGP 10.0 has been shipped.

  It seems to be fixed/supported in a future version?

  Thank you very much .

  This looked interesting so I tried myself. I downloaded a demo of PGP 10.0 and encrypted to my hard drive which has OS X 10.5.8 and a Windows 7 Boot Camp partition.

  After starting the machine virtual Boot Camp in Fusion, I see a black screen that says bootguard _

  

  I guess that's also what you see?

  You're right - it's the PGP bootloader which replaced the Windows loader in the MBR of the physical disk. Fusion accesses the data in the partition through Mac OS X, which already has access to the decrypted data. The boot loader assumes that the drive is always encrypted and fails when he tries to decrypt again.

  Fortunately, Boot Camp VMs include a copy of the MBR (with the boot code and the partition table) in a separate file, so it's very easy to fix:

  #. Start the machine virtual of Boot Camp (not native!) with a Windows CD/DVD installation (or ISO image).

  #. Go to the repair command prompt.

  #. Run the fixmbr command in Windows XP or bootrec /fixmbr in Windows Vista or Windows 7 to replace the MBR code.

  In this way, your Boot Camp virtual machine will use the default Windows boot loader to access the already decrypted data, while the native Boot Camp startup will use code PGP MBR (which is always the physical disk) to access the prompt for the PGP password and decrypt the drive.

  Hello

  Encrypt a script/procedure/KM helps protect the valuable code.

  An encrypted script or KM or a procedure cannot be read or modified if it is not decrypted. Orders generated in the newspaper by a scenario Encrypted KM or procedure are unreadable.

  Oracle Data Integrator uses a personal encryption key-based encryption algorithm. This key can be saved in a file and reused to perform encryption or decryption operations.

  P.S:there is impossible to decipher a procedure without the encryption key or encrypted KM. Therefore, it is strongly recommended to keep this key in a safe place. It is also advisable to use a unique key for all developments.

• Develop the encryption Transparent data with Oracle 10 g XE

  Currently I develop an application that will require encrypted in some tables columns, I will recommended to the customer buying an Oracle database for the application and that you have installed Oracle 10 g XE to begin development, I found that I can't create tables with columns TDE tho I can't create a portfolio. I searched the forums and found that a portfolio manager is not available with Oracle XE.
  
  My plan was to develop the application and then provide scripts for creating the DBA of the customer so that they can create data tables in their Oracle database... Can I develop the application without transparent data encryption and then say s/n, which must be implemented in the version of the application? The application needs to know the password of portfolio/TDE to encrypt/decrypt the columns!
  
  Any ideas how I could go on the development of the customer Oracle XE database without access to CDW?

  The T in TDE is transparent, so that your application should need not even be aware that all columns or storage are encrypted. Transparent data encryption are generally implemented in systems that were never designed to encrypt data, so in theory it should be 'perfectly safe' to develop not encrypted and have the client encrypt the columns during installation.

  Of course, when marketing people start talking about things that are 'perfectly safe', it is always a sign of coming danger. Although I have never heard of a case where encrypt a column caused a problem for an application, I would be very doubtful to the development in an environment different from that of production. This includes the exact version of the database (I guess that the customer has installed the last patchsets, so they run 10.2.0.4, for example) as well as editing. If you decide to rely on the fact that everything should go smoothly when you promote to a different version of a different edition of the database with a different schema definition, even if it would normally, you virtually guarantee that you will end up with a problem that will be difficult to solve.

  In your case, I would use XE to the development. It would be much safer to develop against the personal edition. It's not free, but it's the database licensed Enterprise edition to run on developer machines. It is not free, but it is much less than an enterprise edition license.
