What is AbsoluteLock ?
 AbsoluteLock is a system and harddisk security tool, which uses the only acceptable method to assure a really secure protection solution for your data. After you have installed AbsoluteLock to your system, you will be asked to enter a password everytime you boot your computer. If the password is incorrect the access will be denied, if a user tries to boot from a floppy disk, the protected harddrive(s) will still not be accessable at all.
If you have source codes, other kind of sensetive files or simply want to keep your harddisk locked against others, you need to find a way to secure your system so, that you are the only person who is able to access your data.
You might have already discovered that using the BIOS password protection is simply not safe enough, if you honestly want to protect your system against intruders.
Removing the CMOS battery, using the universial password or replacing a harddisk into another computer system would disclose total access to your data without even knowing your password. Other worthless protection shemes such as a program which is called within autoexec.bat or a driver which gets executed in config.sys are also very easy to be removed. Boot from a floppy disk and you will have full access to your harddrives again, can remove the line in config.sys or where ever it is.
Within Microsoft(R) Windows(TM) several programs offer the possibility to secure folders by asking for a password everytime you want to access the protected folder.
These kind of security products
- slow down your working process,
- folders can usually be accessed from a DOS environment, booted e.g. from a floppy disk,
- cannot protect all data (configuration files, system files...) because these programs only run under Windows and thus conflict with the OS if e.g. the \windows directory would be protected.
Similar weak security offer "protected environment" operation systems such as Windows NT or Windows 2000.
If you want to bypass the LOGIN, you can again simply boot from a floppy disk, if the harddisk uses the NT file system (NTFS) you run a program like NTFDS(5) and you are again able to access all files (patch or delete the SAM file in config32\ and can login into Windows without password).
In fact, most protection system prompt for a password write that password either in encrypted or plain form to disk, when the user wants to log in, the program again prompts for the password and compares it with the one which was written to disk. AbsoluteLock uses a lot more secure variant, it encrypts code which is neccesary for the system to run and even to access the harddrive (either from a floppy boot or from hdd boot). The area which is password encrypted by AbsoluteLock is called "partitiontable", the code which is followed by the masterbootrecord of every IBM, PS/2 or compatible computer system independent which operationsystem is installed. Registered users also have the possibility to encrypt the "bootsector" and do a "partly FAT encryption" for additional security.
Due to this method, the password is neither in plain nor in encrypted form written anywhere to disk.
Which advantages does AbsoluteLock have ?
- Advanced security due to alternative technology to protect harddisk(s)
- No risk of data loss caused by any incompatibilties resulting of already installed bootmanagers or other security tools etc. because AbsoluteLock creates a bootable RescueDisk which can be used to deinstall the protection at any time even if something went wrong
- Operation system independent, has been tested to work with Windows 95/98, Windows NT/2000, DOS, PTSDOS, DRDOS
- Very easy to use, within 1-3 min. also unadvanced users can protect their harddrives against intruders and any kind of unauthorized file access
- AbsoluteLock does not reduce available RAM or harddisk space
