HP JetAdvantage Security Manager 10 Device E-LTU Uživatelský manuál stáhnout pdf (Strana 57)

Security Manager isn’t remediating or downloading firmware to the device, it is merely reading the

device’s Jetdirect firmware version and comparing it with device’s latest Jetdirect version from the

following file over an HTTPS connection:

https://ftp.hp.com/pub/networking/software/jetdirect/firmware/firmware.glf.

If the current device’s firmware version does not match with the latest in the firmware.glf file, then an

assessment failure is shown.

There are three options to choose from to dictate how Security Manager will compare the firmware

versions: File, Web (hp.com), and Best Possible. Web (hp.com) provides the best accuracy as a real

time query is made to the ftp location to ensure the most recent data is being read. However, this

accuracy involves a query outside the company firewall, which may not be desired or possible on the

server. File allows for manually downloading the firmware.glf file at any desired frequency from any

client with web access, then the file can be uploaded into Security Manager to be used for

comparisons in assessments. This eliminates Security Manager having to query outside the firewall as

it will merely read from the file that is uploaded, but accuracy will only be as good as how recently

the file was uploaded. Best Possible combines both techniques, Security Manager attempts to gather

the most recent firmware.glf file from the web, but falls back on an earlier downloaded firmware

index file or can use the user provided firmware.glf file in the case of web connectivity not available.

The frequency or threshold in which Security Manager queries the web for the firmware.glf file is set

to be every 24 hours by default. That means Security Manager will use what has previously been

downloaded for up to 24 hours before it will query the web again for a more current file. The

threshold can be changed if desired in the following file:

C:\Program Files (x86)\HP JetAdvantage Security Manager\HPSM_Service.exe.config

Change the following to define the threshold. Default is 24 hours:

1 2 ... 52 53 54 55 56 57 58 59 60 61 62 ... 115 116
