Foundation Summary

The "Foundation Summary" section of each chapter lists the most important facts from the chapter. Although this section does not list every fact from the chapter that will be on your CCDA exam, a well-prepared CCDA candidate should at a minimum know all the details in each "Foundation Summary" before taking the exam.

The CCDA exam requires that you be familiar with the following topics covered in this chapter:

■ Critical components of the Self-Defending Network:

— Trust and identity management—Securing critical assets

— Threat defense—Responding to the effects of security outbreaks

— Secure connectivity—Ensuring privacy and confidentiality of data communications

— Collaborative security—Security components that work with an organization's security policies

— Adaptive threat defense—Tools used to defend against security threats and varying network conditions

■ Trust and identify technologies:

— Access control lists—ACLs are used on routers, switches, and firewalls to control access

— Firewall—A security device designed to permit or deny network traffic based on source address, destination address, protocol, and port

— Network Admission Control (NAC)—Protects the network from threats by enforcing security compliance on all devices attempting to access the network

— 802.1X—An IEEE media-level access control standard that permits and denies access to the network and applies traffic policy based on identity

— Cisco Identity-Based Network Services (IBNS)—Based on several integrated Cisco solutions to enable authentication, access control, and user policies to secure network infrastructure and resources

■ Threat detection and mitigation technologies:

— PIX—Firewall appliances

— FWSM—Catalyst 6500 Firewall Services Module

— ASA—Adaptive Security Appliance (Robust firewall and/or network-based intrusion prevention system [NIPS])

— IOS firewall—Cisco IOS Software feature set

— IPS sensor appliance (NIPS)

— IPS—Intrusion prevention system (IOS feature)

— NetFlow—Stats on packets flowing through router (IOS feature)

— SNMP—Simple Network Management Protocol (IOS feature)

— MARS—Monitoring, Analysis, and Response System

— Cisco Traffic Anomaly Detector Module detects high-speed denial-of-service attacks

■ Security management solutions:

— Cisco Security Manager (CSM) is an integrated solution for configuration management of firewall, VPN, router, switch module, and IPS devices.

— Cisco Secure Access Control Server (ACS) provides centralized control for administrative access to Cisco devices and security applications.

— Cisco Security Monitoring, Analysis, and Response System (MARS) is an appliance-based solution for network security administrators to monitor, identify, isolate, and respond to security threats.

— Management Center for CSA (CSA MC) is an SSL web-based tool for managing Cisco Security Agent configurations.

— Cisco Router and Security Device Manager (SDM) is a web-based tool for routers and supports a wide range of IOS software.

— Cisco Adaptive Security Device Manager (ASDM) is a web-based tool for managing Cisco ASA 5500 series appliances, PIX 500 series appliances (version 7.0 or higher), and Cisco Catalyst 6500 Firewall Services Modules (FWSM version 3.1 or higher).

— Cisco Intrusion Prevention System Device Manager (IDM) is a web-based application that configures and manages IPS sensors.

■ Integrating security:

— Cisco IOS Firewall

— Cisco IOS trust and identity

— Cisco IOS Routers and Switches

— Adaptive Security Appliance (ASA)

— PIX security appliance

— VPN concentrator

— Catalyst 6500 series service modules

— Endpoint Security

■ Securing the enterprise:

— Identity and access control—802.1X, NAC, ACLs, and firewalls

— Threat detection and mitigation—NetFlow, Syslog, SNMP, RMON, CS-MARS, NIPS, and HIPS

— Infrastructure protection—AAA, TACACS, RADIUS, SSH, SNMP v3, IGP/EGP MD5, and Layer 2 security features

— Security management—CSM, CS-MARS, and ACS
