System Description
Cisco Security MARS is a security threat mitigation (STM) system. It delivers a range of information about your networks' health as reported by devices in your networks. It processes raw events from your reporting devices, sessionizes1 them across different devices, evaluates for matching inspection rules (system and user-defined), identifies false positives, and consolidates information using diagrams, charts, queries, reports, and rules.
MARS helps you be more productive by:
•
Reducing the amount of raw data that requires manual review
•
Enabling an evolving view of the network security posture
•
Identifying hot spots of malicious activity
•
Blocking undesirable traffic from the network
The MARS system operates at distinct and separate levels based on how much information is provided about your networks' reporting devices. At its most basic level, MARS functions as a syslog server. As you add information about reporting devices, MARS begins to sessionize the raw data, and after you configure additional reporting devices and enable the more verbose reporting features, it presents a much more comprehensive view of your network, from which you can quickly drill-down to a specific MAC address, for example.
Figure 1-1 presents an example deployment of MARS, which identifies the components of the system and their relationships.
Figure 1-1 Relationship of Global Controller to Local Controller to Reporting/Mitigation Device
The Cisco Security MARS system comprises the following components:
•
Local Controller
•
Global Controller
•
MARS Web Interface
•
Reporting and Mitigation Devices
Local Controller
The Local Controller models are as follows— MARS 110R, MARS 110, and MARS 210. Each model differs in its ability to process and store events from reporting devices, enabling you to accurately address your needs based on the size of your network and the traffic volume.
Local Controllers receive and pull data from reporting devices, such as firewalls, routers, intrusion detection/prevention systems, and vulnerability assessment systems. Based on the data obtained from those devices, and the level of integration with them, MARS can present you with suggested mitigation rules for detected attacks and, in some cases, push those rules to the mitigation device, which is a network device that contains the attack by restricting network access to the infected hosts.
A Local Controller summarizes information about the health of your network based on data it receives from the reporting devices that it monitors.
The Local Controller performs the following functions:
•
Collects all raw events
•
Sessionizes events across different devices
•
Fires inspection rules for incidents
•
Determines false positives
•
Delivers consolidated information in diagrams, charts, queries, reports, and notifications
•
Detects inactive reporting devices
•
Derives set of IOS/IPS Distributed Threat Mitigation (DTM) signatures based on attacks reported by monitored CISCO IPS 5.x appliances
•
Acts as a repository for the IOS/IPS DTM signatures, from which IOS/IPS devices can download current signature sets
Global Controller
If you deploy numerous Local Controllers, you can deploy a Global Controller that summarizes the findings of two or more Local Controllers. In this way, the Global Controller enables you to scale your network monitoring without increasing the management burden. The Global Controller provides a single user interface for defining new device types, inspection rules, and queries, and it enables you to manage Local Controllers under its control. This management includes defining administrative accounts and performing remote, distributed upgrades of the Local Controllers. The Global Controller is available in the following models—MARS GC2 and MARS GC2R.
MARS Web Interface
The MARS web interface operates on a client computer. With many features common to both the Local Controller and Global Controller, the web interface uses a tabbed, hyperlinked, browser-based user interface. You access the web interface from any computer that can access the MARS Appliance on your network. For more information on client requirements, see Web Browser Client Requirements, page 3-10.
From the web interface, you can perform most of your administrative functions, including all functions that are not supported at the command line. Although this manual includes procedures for initially configuring the appliance using the web interface, the following publications reference their corresponding web interface:
•
User Guide for Cisco Security MARS Local Controller
•
User Guide for Cisco Security MARS Global Controller
Reporting and Mitigation Devices
If you consider the MARS system from a top-down perspective, you see that the Global Controller monitors Local Controllers and that Local Controllers monitor one or more reporting devices. Reporting devices provide MARS with data about the network, from traffic flows, as in the case of a router, to the configuration of possible attack targets, such as from a vulnerability assessment system.
A reporting device that can deny a traffic flow is called a mitigation device (for example, a switch). MARS provides mitigation support in two forms:
•
For supported Layer 3 devices (based on the OSI Network Model), MARS provides you with a suggested device and set of commands that can be used to halt an ongoing, detected attack. You can use this information to manually block the attack.
•
For supported Layer 2 devices, MARS recommends a device, a set of commands to halt the ongoing, detected attack, and provides a method for making the configuration changes on your behalf.
How you configure your reporting devices and mitigation devices greatly affects the ability of MARS to detect ongoing attacks. You can learn more about how to configure these devices in the following:
•

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.
|
Network Cable Requirements
The Ethernet connectors are designed for attaching an unshielded twisted pair (UTP) Ethernet cable equipped with standard RJ-45 compatible plugs. Press one end of the UTP cable into the Ethernet connector until the plug snaps securely into place. Connect the other end of the cable to an RJ-45 port on a hub or other device, depending on your network configuration. Observe the following cabling restrictions for 10BASE-T, 100BASE-TX, and 1000BASE-TX networks:
•
For 10BASE-T networks, use Category 3 or greater wiring and connectors.
•
For 100BASE-TX and 1000BASE-TX networks, use Category 5 or greater wiring and connectors.
•
The maximum cable run length is 328 feet or 100 meters.

10/100/1000-megabit-per-second (Mbps) autosensing Ethernet ports (autosensing detects line speed and duplex mode). MARS supports the operation of both Ethernet connectors. Table 1-7 lists LED descriptions. NIC 1 is eth0 and NIC 2 is eth1.
Each Ethernet connector provides all the functions of a network expansion card and supports the 10BASE-T, 100BASE-TX, and 1000BASE-TX Ethernet standards.
The MARS Appliance monitors network traffic destined to the IP address assigned to eth0. The eth0 connector is the port to which the gateway command applies. Therefore, eth0 must be attached to the network from which the reporting devices are accessible. The eth1 connector is typically used as an out-of-band management network, which provides faster graphical user interface (GUI) response to the administrator. To use eth1, you must define static routes to the destination networks for that interface.

Over-Temperature Protection (OTP)
The power supply is protected against over-temperature conditions caused by loss of fan cooling or excessive ambient temperature. In an OTP condition the power supply will shutdown. When the power supply temperature drops to the rated safety limit, the power supply restores power automatically, while the 5 V standby remains constantly on. The power supply alerts the system of the OTP condition with the power supply FAIL signal and the Power LED on the control panel.
Over-Current Protection (OCP)
The power supply and power distribution board shutdown and latch off after an over-current condition occurs. This latch is cleared by an AC power interruption.
Over-Voltage Protection (OVP)
The power supply and power distribution board shutdown and latch off after an over-voltage condition occurs. This latch is cleared by an AC power interruption.
AC Power Source Requirements
Each power supply has a socket to accommodate an AC power cord. Each power supply operates within the parameters listed in Table 1-10.

Power Supply LED Descriptions
Each power supply module has a two-color Amber/Green LED to indicate power supply status.
•
Solid amber—Indicates no AC power for this power supply unit only, or there is a power supply critical event causing a shutdown. For instance, a general failure, a blown fuse, an over-current protection event, an over-voltage protection event, or a fan failure.
•
1Hz blinking amber— Power supply warning event is occurring and the power supply is operating. Warning events are high temperature, high power, high current, or slow fan.
•
Solid green—Power supplies are operating normally
•
1Hz blinking green—AC power is present but only 5V standby is on (Power Button is off)
Checking Power Supply Operational Status
Example 1-1 displays the power supply status information in an excerpt of a show healthinfo CLI command output. The power supply unit should evaluated for hotswapping if the status is down. An email alert is sent to the administrator when a power supply changes status from "ok." PS1 is the lower power supply, PS2 is the upper power supply. In normal operation, PS1 supplies most of the power requirements, and PS2 is the redundant power supply.
Example 1-1 Power Supply Status in the show healthinfo CLI Command.
