Skybox Appliance 7000 Quick Start Guide

Skybox version 11.7.100

68

RECOMMENDATION

SCORED

DESCRIPTION

password when authenticating with SSH.

5.2.7

ü

Ensure that SSH

HostbasedAuthentication

is

disabled. The

HostbasedAuthentication

parameter

specifies whether authentication is permitted through
trusted hosts via the user of

.rhosts

, or

/etc/hosts.equiv

, along with successful public key

client host authentication. This option only applies to SSH
Protocol Version 2.

Rationale: Even though the

.rhosts

files are ineffective if

support is disabled in

/etc/pam.conf

, disabling the

ability to use

.rhosts

files in SSH provides an additional

layer of protection.

5.2.15

ü

Ensure that SSH access is limited. There are several
options available to limit the users and groups that can
access the system via SSH.

l

AllowUsers: The

AllowUsers

variable gives the

system administrator the option of permitting specific
users to SSH into the system. The list consists of
space-separated user names. Numeric user IDs are not
recognized with this variable. If a system administrator
wants to restrict user access further by only permitting
these users to log in from a particular host, the entry
can be specified in the form of

user@host

.

l

AllowGroups: The

AllowGroups

variable gives the

system administrator the option of permitting specific
groups of users to SSH into the system. The list
consists of space separated group names. Numeric
group IDs are not recognized with this variable.

Rationale: Restricting the users who can remotely access
the system via SSH helps ensure that only authorized
users access the system.

5.2.16

ü

Ensure that the SSH warning banner is configured. The

Banner

parameter specifies a file whose contents must be

sent to the remote user before authentication is permitted.
By default, no banner is displayed.

Rationale: Banners are used to warn connecting users of
the particular site’s policy regarding connection.
Presenting a warning message prior to the normal user
login may assist the prosecution of trespassers on the
computer system.

5.3.1

ü

Ensure that password creation requirements are
configured. The

pam_pwquality.so

module checks the

strength of passwords. It performs checks including
making sure that a password:

l

Is not a dictionary word

l

Is a certain length

l

Contains a mix of characters (for example, alphabet,
numeric, other)

l

And more
