SNMP v3 trap.

SHA (Secure Hash Algorithm) are hash algorithms used to authenticate SNMP data. SHA
authentication is generally considered stronger than MD5, but is slower.
Privacy This displays the encryption method for SNMP communication from this user. Methods
available are:
• DES - Data Encryption Standard is a widely used (but breakable) method of data
encryption. It applies a 56-bit key to each 64-bit block of data.
• AES - Advanced Encryption Standard is another method for data encryption that also
uses a secret key. AES applies a 128-bit key to 128-bit blocks of data.
Privlege This displays the access rights to MIBs.
• Read-Write - The associated user can create and edit the MIBs on the ZyWALL/USG,
except the user account.

MIBs.
Service Control This specifies from which computers you can access which ZyWALL/USG zones.

The entry with a hyphen (-) instead of a number is the ZyWALL/USG's (non-configurable)
default policy. The ZyWALL/USG applies this to traffic that does not match any other
configured rule. It is not an editable rule. To apply other behavior, configure a rule that
traffic will match so the ZyWALL/USG will not have to use the default policy.
Zone This is the zone on the ZyWALL/USG the user is allowed or denied to access.
Address This is the object name of the IP address(es) with which the computer is allowed or denied
to access.
Action This displays whether the computer with the IP address specified above can access the
ZyWALL/USG zone(s) configured in the Zone field (Accept) or not (Deny).
