Sysmask is a security solution designed for Linux systems. It can protect
the system integrity against vulnerabilities in the great majority of codes,
whether known or unknown, patched or non-patched, in user programs,
libraries or the kernel.
Sysmask can be configured to restrict the access of a process or a user to
system resources: files, sockets, devices, system calls, disk space, memory
usage. The restriction policy can be defined with great precision, sometimes
contextual. Processes with tightly restricted access rights may continue to
do their normal work as before, but if they are compromised, the malicious
code that gets run will be unable to harm the system except for the job that
is assigned to the compromised process.
A fully deployed sysmask can protect the system against any vulnerability
except those in a small portion of the kernel, which is historically very
solid, plus those in the sysmask package itself.
With respect to other security solutions, several novel features have been
introduced in sysmask.
1. It offers protection against most kernel vulnerabilities that occur or
will occur in practice, by allowing selective closure of unused system
calls and activities for untrusted processes or users.
2. Using configuration definitions with a simple user-friendly syntax,
interactive security reactions can be defined in various ways, leading to
flexible and highly customizable security schemes without the need to
recompile existing softwares nor even to modify their configurations.
Custom interactive reactions greatly enhance the security level, as the
system behavior becomes unpredictable to outside attackers with no knowledge
of these reactions.
3. It can protect against both system level risks (unauthorized accesses
etc.) and user level risks (viruses etc.), and includes efficient resource
consumption limitations that overcome the shortcomings of traditional rlimit
setups.
4. It supports runtime reconfiguration with a menu-based user interface that
accepts feedback configuration.
Sysmask introduces only minimal or negligeable performance overhead, except
for a few programs under special conditions and requiring highly selective
protection.
The package of sysmask is also very simple and compact, with its critical
parts independent of outside codes (libraries), minimizing the probability
of bugs contained in the package itself.
Sysmask allows you to radically reduce the need to update your system
components for security reasons, because you can now live with
vulnerabilities without being hurt. Traditional anti-virus scanners are no
longer needed, let alone the need to update them, because sysmask can
prevent any virus from being installed. |

While WinNT/2K and Windows 9x's built-in Label utility lets you change the labels of disk volumes, it does not provide any means for changing volume ids. This utiltity, VolumeID, allows you to change the ids of FAT and NTFS disks (floppies or hard drives) on both Windows NT/2K and Windows 9x.
Usage: volumeid <driveletter:> xxxx-xxxx
This is a command-line program that you must run from a command-prompt window.
Note that changes on NTFS volumes won't be visible until the next reboot. In addition, you should shut down any applications you have running before changing a volume id. NT may become confused and think that the media (disk) has changed after a FAT volume id has changed and pop up messages indicating that you should reinsert the original disk (!). It may then fail the disk requests of applications using those drives. |

UNIX provides a standard utility called Sync, which can be used to direct the operating system to flush all file system data to disk in order to insure that it is stable and won't be lost in case of a system failure. Otherwise, any modified data present in the cache would be lost. Here is a an equivalent that I wrote, called Sync, that works on all versions of Windows. Use it whenever you want to know that modified file data is safely stored on your hard drives. Unfortunately, Sync requires administrative privileges to run. This version also lets you flush removable drives such as ZIP drives.
Usage: sync [-r] [-e] [drive letter list]
-r Flush removable drives.
-e Ejects removable drives.
Specifying specific drives (e.g. c e ) will result in Sync only flushing those drives. |
