Multiple security features has been integrated over a single named as Layer 8 Identity based platform which make security look very simple, but highly effective.

How does Cyberoam Functions?
While designing corporate policies regarding network security, many organizations often neglect the most critical and weak component in security, that is the human element. By and large an organization’s overall security is only as strong as its weakest link, their users. In order to deal with the concerns of gaining visibility and controls on the users activities in the network, Cyberoam UTM’s Layer 8 technology with its network appliances of UTM appliances and Next Generation Firewalls, has been derived out of the need for a more strong network security system which can include a user’s human identity as part of the firewall rule matching the criteria.

How does Cyberoam Layer Technology functions?
By definition, Cyberoam Layer 8 Technology, functions over its network security appliances by treating every single user identity as the 8th layer or the "human layer" in the network protocol stack. This allows the system administrators to uniquely identify users, control activity of these users in the internet network, and enable policy setting and reporting by username.

What are the Benefits of Cyberoam’s 8 Layer Technology?
Following are the benefits rendered by Cyberoam’s 8 Layer Technology: -
1. Identification of attackers and victims with their username can be identified.
2. Instant visibility by system administrators into source of the attacks.
3. Controlling who is doing what in the entire organizational network.
4. Allowing creation of identity-based policies
5. Reporting to track identity-based usage, problems, intrusions and so forth.

What do you mean by integrated security over single Cyberoam network security appliances?
The Layer 8 technology goes through each and every single security module of the Cyberoam security appliances. All security features are centrally configured and are managed from a single firewall page easily. Layer 8 binds these securities features and creates a single, consolidated security unit which enables the system administrator to change security policies dynamically while accounting for user movement, like joiner, leaver, elevating hierarchy etc.

How Cyberoam does adds speed to the security system?
IT professionals often waste much time in the knowing source of attacks or attackers in any case of security breach, due to the lack of granular identity features in other security systems. Cyberoam’s Layer 8 provides instant visibility into the source of attacks while identifying victims and attackers by their username followed by a proactive remedy of security incidents. In this way Cyberoam speeds up the security.

Cyberoam’s content and application filtering mechanism manages the indiscriminate Internet surfing tendency of its users through customized policy setting for different users and groups, thereby marking limitations on access based on time duration and predefined blocked sites over 100 categories. Cyberoam network security appliances also provides all users with time and role based bandwidth management system which prevents users from consuming huge amounts of bandwidth for nonproductive internet surfing and unnecessary downloads. Instant Messaging Controls allow administrators to control who can chat with whom over messengers, webcam and can transfer files.

What is this Cyberoam captive portal and how can it be configured?
A Captive Portal is used to validate an existing user in Cyberoam network through a web browser interface before granting access to the network. Cyberoam allows system administrators to modify URL redirection after any user logs in through the Captive Portal. 

Why is Captive Portal not displayed to users trying to access Internet when a default Drop Policy is applied?
This problem may be specific to some installations only and can spread to multiple locations. However, two common issues occurs which are described as follow: - 
1. An External DNS is configured in the specific System. If a ‘Drop’ firewall rule is applied, Cyberoam will block all traffic, including DNS requests. Hence, Captive Portal won’t be displayed. This can resolved by either of the following solutions:

a) We should Configure Cyberoam IP address as the DNS in the user machines.
b) We should create a firewall rule which accepts DNS traffic and places it above the ‘Drop’ rule.

2. Captive Portal is not displayed for Clientless Users. This happens because trusted users don’t need any authentication on Cyberoam to access Internet. Hence, Captive Portal is not displayed to clientless users.

How to customize the Default SMS sent to Guest Users?

What is a firewall on a network?

What is a DMZ in networking?
In network security, a DMZ or demilitarized zone (known as a perimeter network also) is a physical or logical sub network which points their external services to an network not trusted, generally a large network like that of the Internet.

Why do we need a DMZ?
The second or internal firewall permits traffic only from the DMZ to the internal network. This is perceived to be more secure since two devices would need to be compromised before an attacker can access the internal LAN. As a DMZ segregates a network, security controls can be perfectly tuned for each and every single segment.
