Applicable to Version: 10.00 onwards

A network is only as secure as its weakest link. The Cyberoam UTM sits as the access control gateway between the trusted LAN and the un-trusted WAN. It is most importance to strengthen Cyberoam UTM Deployment in order to secure the network.

This document has three (3) sections:

·         Access to Web Admin Console

The entire configuration is to be done from Web Admin console. Access Web Admin Console with user having “Administrator” profile.

Change Default Credentials for Web Admin Console

Cyberoam version 10 is shipped with a default super administrative user, which has all the privileges with the following credentials:

Username: admin

Password: admin

Apart from Web Admin Console, CLI can also be access with this password.

We recommend that you change password of this super administrator immediately after deployment. As this account has the super admin privileges for both the consoles, please set complex password that is a combination of a-z, A-Z, 0-9 and special characters. An example of a complex password can be “@Dm1nAcC3s$”.

 

Refer the below attached PDF for the link to change the super administrator password:


Cyberoam is shipped with other default administrator user with credentials: cyberoam/cyber. This user has full privileges of Web Admin Console but cannot access CLI while super administrative user has full privileges of Web Admin Console as well as CLI.
 

Refer the below attached PDF for the link to change the password for default administrator user “cyberoam”

Role Based Administration

Cyberoam provides role-based administration capabilities through profiles to offer greater granular access control and flexibility. Profiles are a function of an organization's security needs and can be set up for special-purpose administrators in areas such as firewall administration, network administration, and logs administration. Profiles allow assigning permissions to individual administrators depending on their role or job need in organization.


The profile separates Cyberoam features into access control categories for which you can enable none, read only, or read-write access.
