Cyberoam firewall is the only UTM firewall that embeds user identity in firewall rule matching criteria, enabling enterprises to configure policies and identify users directly by the username rather than through IP addresses. Cyberoam’s powerful hardware firewall provides stateful and deep packet inspection, access control, user authentication, network and application-level protection.

Select public IP address type and configure IP address. The configured IP address is mapped to the destination host/network and used as the IP address of the virtual host. Select mapped IP address type and configure IP address. It is the IP address to which the public IP address is mapped. This is the actual private IP address of the host being accessed using the virtual host.

Create a Firewall rule from WAN to DMZ as the Web Server is located in DMZ with destination as the Virtual host for the Web Server created.
There is no need for the administrator to create loop back rule explicitly. It will be created automatically whenever a Virtual Host is created. This means c reating a virtual host will create a DMZ-DMZ rule by default. These rules allow internal users to access the resource on same public IP. Whenever a Virtual Host will be selected as Destination of a Firewall Rule, it is annotated as (VH) and by taking the cursor of mouse over it, it displays the mapping of public IP address with mapped IP address.
A "denial-of-service" attack is characterized by an explicit attempt by attackers to prevent legitimate users of a service from using that service. Examples include: flooding a network, thereby preventing legitimate network traffic; disrupting a server by sending more requests than it can possibly handle, thereby preventing access to a service; preventing a particular individual from accessing a service; disrupting service to a specific system or person
A SYN flood attack creates so many half-open connections that the system becomes overwhelmed and cannot handle incoming requests any more. UDP Flood: This attack links two systems. It hooks up one system’s UDP character-generating service, with another system’s UDP echo service.Once the link is made, the two systems are tied up exchanging a flood of meaningless data. Tcp flood : This attack sends huge amount of TCP packets than the host/victim computer can handle. ICMP flood is based on sending the victim an overwhelming number of ping packets. It is very simple to launch, the primary requirement being access to greater bandwidth than the victim.
DoS Protection settings vary for different organizations give example
When the burst rate is crossed, Cyberoam considers it as an attack. Cyberoam provides DoS attack protection by dropping all the excess packets from the particular source/destination. Cyberoam will continue to drop the packets till the attack subsides. Because Cyberoam applies threshold value per IP address, traffic from the particular source/destination will only be dropped while the rest of the network traffic will not be dropped at all i.e. traffic from the remaining IP addresses will not be affected at all.
Explain the relationship between policies Explain how different categories make an IAP and how different policies Can be applied to a User. User Identity-based Policies Cyberoam’s user identity-based filtering provides the granular controls required to control access by individual users and groups to applications, sites, information upload, as well as entry of virus, worm, spyware and other attacks on the network. By allowing enterprises to set distinct surfing policies with differing access rights based on individual names rather than IP addresses, Cyberoam enables the creation of surfing policies based on the user’s work profile. Policies can be created based on the user’s department, group, hierarchy or individual requirements, providing great dynamism and flexibility in policy creation and management. Rapid user-IP mapping with instant user identity recognition reduces time lag and processor load. Group is a collection of users having common policies that can be managed as a single unit. Its a mechanism of assigning various policies to a number of users in one operation/step. It simplifies the user configuration. Users that belong to a particular group are referred to as a group user. Users are needed for Auditing and Security can be configured at more finer granule Isolation point can be identified immediately Integration will identify access request based on User names Generate reports based on Usernames
Threats over email like spam, phishing, viruses, worms, are released in the billions within a short span of time. Today’s attackers launch threats for financial gain rather than out of malicious intent. They mask the originator and launch the attack using a network of zombie machines. With Zombie botnets carrying the ability to send up to 1 billion spam messages within a few hours, the spread of the attack is rapid. Gateway level spam protection for Zero-hour spam detection To effectively match the speed with which attacks spread, zero-hour responsiveness is required to deliver enterprise security. Zero-hour protection swings into action, generating defenses in the first hour of an attack. Further, the content and characteristics of the message within a single attack differ, making it difficult to identify the threat through traditional methods. Solutions that rely on signature databases are likely to leave the enterprise defenses lowered during the critical first hours of attack. Cyberoam in Partnership with CommTouch RPD (Recurrent Pattern Detection) Cyberoam delivers zero-hour spam protection in addition to image spam defense though Recurrent Pattern Detection (RPD) technology. This unique content-agnostic technology detects and blocks image spam which accounts for almost 35 % of worldwide spam mail and 70% of bandwidth taken by spam. Cyberoam’s anti-spam protection delivers maximum spam detection with low false positives through relevant, continuous and real-time spam detection. The solution reduces spyware, phishing and adware attempts, controls spam involving pornography while enhancing enterprise productivity by preventing mail systems from being submerged by spam
