Security

Authentication continued

MD5

authentication

(Web interface),

continued

If you use

MD5

authentication, which is available only for the Web

interface, disable the less secure interfaces, including Telnet,

FTP

, and

SNMP

. For

SNMP

, you can disable write-only access so that read

access and trap facilities are still available.

Although

MD5

authentication provides a much higher level of security

than the plain-text access methods, complete protection from security

breaches is almost impossible to achieve. Well-configured firewalls are

an essential element in an overall security scheme. For additional

information on

MD5

authentication, see

RFC

document #

1321

at the

Web site of the Internet Engineering Task Force. For

CHAP

, see

RFC

document #

1994
