Snmp Security Guidelines - HP 3500yl Series Access Security Manual

This page allows you to choose between two setup types:
Typical—provides a multiple page, step-by-step method to configure
•
security settings, with on-screen instructions for each option.
• Advanced—provides a single summary screen in which to configure
all security settings at once.
Refer to the WebAgent Online Help for detailed information about using the
Management Interface wizard.

SNMP Security Guidelines

In the default configuration, the switch is open to access by management
stations running SNMP (Simple Network Management Protocol) management
applications capable of viewing and changing the settings and status data in
the switch's MIB (Management Information Base). Thus, controlling SNMP
access to the switch and preventing unauthorized SNMP access should be a
key element of your network security strategy.
General SNMP Access to the Switch. The switch supports SNMP
versions 1, 2c, and 3, including SNMP community and trap configuration. The
default configuration supports versions 1 and 2c compatibility, which uses
plain text and does not provide security options.
HP recommends that you enable SNMP version 3 for improved security.
SNMPv3 includes the ability to configure restricted access and to block all
non-version 3 messages (which blocks version 1 and 2c unprotected
operation).
SNMPv3 security options include:
configuring device communities as a means for excluding management
■
access by unauthorized stations
■ configuring for access authentication and privacy
■ reporting events to the switch CLI and to SNMP trap receivers
restricting non-SNMPv3 agents to either read-only access or no access
■
■ co-existing with SNMPv1 and v2c if necessary
SNMP Access to the Authentication Configuration MIB. Beginning
with software release K.12.xx, a management station running an SNMP
networked device management application, such as HP PCM+ or HP
OpenView, can access the switch's management information base (MIB) for
read access to the switch's status and read/write access to the switch's
