<div class="description">
|
||
|
|
<p>Verified Executables (Veriexec) ist ein kernelbasiertes Verfahren zur Steigerung
|
||
|
|
des Vertrauens in Dateien, die auf einem System, vorzugsweise eines
|
||
|
|
Serversystems, aufliegen. Über ein Pseudo-Device wird eine Liste von Pfäden
|
||
|
|
von Dateien mitsamt ihren Fingerprints und Typattributen in den Kernel geladen,
|
||
|
|
womit das NetBSD-System in den zickigen Modus überführt werden
|
||
|
|
kann, sich zu weigern Dateien auszuführen oder auch nur schon zu lesen, die
|
||
|
|
einen veränderten Fingerprint aufweisen. Als Hashverfahren können alle
|
||
|
|
eingesetzt werden, die von cksum(1) unterstützt werden und diese können in
|
||
|
|
einer Dateienliste auch je Datei gemischt verwendet werden. Zudem kann zwischen
|
||
|
|
verschiedenen Strict Modi unterschieden werden, die das Systemverhalten beim
|
||
|
|
Vorliegen hashveränderter Dateien beeinflussen. Die Systemgeschwindigkeit wird
|
||
|
|
dank eines Cache-Verfahrens nur unmerklich beeinflusst.</p>
