Overview of K1000 Services, Ports, and Protocols
• Primary
communications are
HTTPS traffic
• Select optional
protocols wisely and
only when needed
• Arrows indicate
direction to open the
port on any firewalls

3. Dell World User Forum
Inside the Intranet
• Safest approach to deployment
• Consider keeping appliance service
ports restricted to the data center
• Window for collecting inventory and
deploying digital assets, including
patching, is restricted to when users
are present on network

4. Dell World User Forum
Within the DMZ
• Use this deployment when
serving highly mobile users
• Be more diligent when
opening service ports
• Consider alternate methods
if database access is desired

5. Dell World User Forum
Securing Web Traffic:
Securing Web Protocols
• Use SSL, regardless of
deployment choices
• Complete SSL configuration
before deploying agents
• Up to 2048 Bit encryption is
supported
• Enable SSH during configuration
in the event assistance from
Dell KACE Technical Support is
needed
• Use a certificate from a vendor in
trusted certificate vendor list or
your organization’s Root CA
certificate

6. Dell World User Forum
Controlling Access with Access Control Lists
• Restricts access to the UserUI,
AdminUI, and SystemUI to
certain ranges in the network
• Restrict access to the AdminUI
and SystemUI to the LAN
environment where administrators
will administer the K1000

7. Dell World User Forum
Securing the Agent
• Open ports 443 and 52230 outbound
on any local firewall
• SSL is enabled on AMP by default when
SSL is configured on the server
• Use SSL for the agent as well as
the Uis
• Restrict LocalSystem administrator
rights on your endpoints

8. Dell World User Forum
Securing Replication Shares
• Ensure write access to replication
shares is restricted
• Configure a Destination User and
Password for the replication share
that is not used for other purposes
• A Destination User and Password
does not need to be set if the
Replication Device is also the host
for the replication share
• Ensure that the Read-Only Download
User and Password are not used for
other purposes and are unique from
the Destination User and Password

9. Dell World User Forum
Replication Share Data Flow
• Deployment Choices
• HTTP vs file transfer
• Replication Device on
replication share vs.
Replication Device
remote from replication
share

10. Dell World User Forum
Configuring a Proxy for Web Feeds
• Reference KB article 118543 for patch download
URLs
• For geographically load-balanced services, use
the Classless Internet Domain Routing (CIDR)
for whitelisting

11. Dell World User Forum
Securing Database Access
• Use the onboard reporting engine to access
the database
• If external database access is desired,
configure the connection to use SSL
• Set the read-only passwords to each org’s
database to a strong value
• If a DMZ deployment is desired, consider
using a secondary K1000 for reporting purposes
with a periodic restore from the nightly backup of
the production K1000.
• Port 3306 inbound must be opened on any firewall
between the machine with the external reporting tool
and the K1000

12. Dell World User Forum
Utilizing History for Audit and Change Control
• Set tracking and retention policies for K1000
Settings, Assets, and Objects based on what
you are using and your local risk assessments
• Match your retention policies to your audit
processes so that you don’t burden the K1000
database with old records you’ve already
reviewed

13. Dell World User Forum
Configuring User Authentication with LDAP
• Use LDAP authentication whenever possible to
leverage enterprise password change policies
• LDAP configurations can be different for each
org
• Set a strong password for the default admin
account and use it only for recovery purposes
• Define a default access role with minimum
privileges to be assigned to authenticated users
on import
• Manually assign roles with elevated privileges
to only those users that require them
• If using Active Directory, you may consider
applying SSO with Windows credentials. Only
one org may use SSO

Service Desk
• Use the pre-defined Admin role to
authorize only those users who will
function as K1000 system administrators
• Use the pre-defined User role to
authorize users who will be accessing
the User UI for self-service
• Define specialized roles for users who
have responsibility to view or update only
certain aspects of the K1000
• Define specialized roles for any
administrators who will use K1000 admin
features but will not act as K1000 system
administrators
• Import user attributes from LDAP to more
effectively manage role assignments,
create user labels, and assign asset
ownership

15. Dell World User Forum
Securing Backups
• Enable the Secure Backup Files option to prevent backup files from being downloaded via
HTTP/S
without authentication
• Use FTP to retrieve backups to external storage on a nightly basis in accordance with your
defined
backup schedule
• Set the FTP password in accordance with your password policies. You should use a new
password created solely for this purpose rather than reusing a common FTP service password
• You should know explicitly where your last good backup is located and secure access to that
backup
• Only enable Make FTP Writeable when you need to conduct a restore to your K1000 AND your
backup files exceed 2 gigabytes. Once the restore is complete, disable this setting.
• Evaluate your history retention policies and make adjustments to reduce the size of your backup
files if necessary.

16. Dell World User Forum
Securing Agent Provisioning
• Enable the onboard SAMBA share only when
you need to transfer files to or from the K1000
(e.g. if you will be using K1000 agent
provisioning)
• Consider using GPO scripts or any other
existing distribution mechanism to deploy the
agent
• KB Article 133776 describes the GPO
Provisioning Tool
• If using K1000 agent provisioning, consider
transferring the agent installation files to an
established network share in your environment
and configuring an alternate location within
K1000 agent provisioning
• When possible, provision agents using DNS
hostname to ensure the appropriate endpoints
are being configured with the agent

17. Dell World User Forum
Securing Inbound Email
• Use an alternate email address defined in
your existing email services, which will be
mapped to the K1000 service desk queue
• Accept email on the service desk queue
only from users that have been configured
within the K1000 as users of the appliance
• If possible, locate the K1000 and an MTA for
your existing email services within the same
subnet and with MX records in DNS defined
to exchange SMTP messages between your
MTA and the K1000
• If encryption of email is desired, use the
SPOP3 protocol for retrieving inbound email
from your existing email services

18. Dell World User Forum
Securing Outbound Email
• Consider configuring an SMTP server within
your existing email services to receive
outbound mail from the K1000
• If possible, locate this external SMTP server
in the same LAN as the K1000
• Configure an email alias for your K1000
system administrators that will receive daily
status emails from the K1000 including
notifications of any security breaches

19. Dell World User Forum
Configuring Appliance Service Protocols
• When enabling SNMP Monitoring of the K1000,
configure an SNMP community string that is specific
to your environment rather than using the default
‘public’ string
• There is no provision within the K1000 for configuring
SNMP traps to be sent to your SNMP monitoring tool.
Therefore, you can only scan the K1000 periodically
for SNMP information
• If you enable SNMP monitoring, open port 161
outbound on any firewall that must be traversed
• Only enable SSH when engaging with Dell KACE
Technical Support or when planning periodic
maintenance of your K1000. Disable it when done.

20. Dell World User Forum
Securing the Console
• Ensure that access to the K1000 console is
restricted to K1000 system administrators only
• If a remote access technology is being used
(e.g. DRAC, vSphere console, KVM), ensure
access to the K1000 console is protected
with a strong password
• .
