What is a VPN?
Cisco Documentation on VPN
• A VPN is a Virtual Private Network
• Now, as more and more companies need access for remote users, mobile
users or remote offices, your current architecture can be augmented with a
• A Virtual Private Network is a network that’s created by encryption
(Tunneling) across another unsecured medium, like the Internet
• What is great about Cisco and VPN’s is that all Cisco devices can be
configured as a VPN enabled device solely by the IOS feature set itself. There
is a concentrator series, but...
CCSP Cisco Secure VPN Exam Certification Guide is a comprehensive study tool that enables you to master the concepts and technologies required for success on the CSVPN exam. Each chapter of the CCSP Cisco Secure VPN Exam Certification Guide tests your knowledge of the exam subjects through sections that detail exam topics to master and areas that highlight essential subjects for quick reference and review.
This paper is the second in a three-part series of white papers, each of which focuses on a functional area of
securing your network. As introduced in the first installment, network security should be implemented throughout
your entire network. Take a layered approach and introduce security at every layer possible. This second
paper will suggest steps to secure your Router, Firewall, and Virtual Private Network (VPN) Concentrators.
This document serves as a design guide for those intending to deploy a site-to-site VPN based on IP
Security (IPsec). The designs presented in this document focus on Cisco IOS VPN router platforms.
The primary topology described in this document is a hub-and-spoke design, where the primary
enterprise resources are located in a large central site, with a number of smaller sites or branch offices
connected directly to the central site over a VPN. A high-level diagram of this topology is shown in
The Cisco Certified Security Professional (CCSP) certification is the newest midlevel certification
from Cisco Systems. This certification is on a par with CCNP and CCDP. The aim of this
certification is to provide professional-level recognition to network engineers in the design and
implementation of Cisco secure networks. This certification provides validation of knowledge and
skills in key areas of security, including firewalls, intrusion detection, VPNs, identity, and security
This chapterdiscusses the concept of borderless Networks. It discusses Cisco borderless Network architecture, including the components and underlying technologies. You will learn about the Cisco security portfolio products that address specifically issues of borderless Networks, and more precisely about Cisco SecureX. This chapter introduces Cisco threat control and containment products and VPN technologies that will be covered in greater detail in subsequent chapters.
This chapter describes the use cases and operational requirements of SSL VPNs and offers a detailed presentation on the operations of SSL. The chapter explains configurations, deployment options, and design considerations. It describes the steps to configure both Cisco VPN clientless mode and Cisco full-tunnel mode on Cisco ASA using the Cisco AnyConnect client.
In an age when our society relies so heavily on electronic communication, the need
for information security is imperative. Given the value and confidential nature of the
information that exists on today’s networks, CIOs are finding that an investment in
security is not only extremely beneficial but also absolutely necessary. Corporations
are realizing the need to create and enforce an information security policy.
This design guide defines the comprehensive functional components required to build a site-to-site
virtual private network (VPN) system in the context of enterprise wide area network (WAN)
connectivity. This design guide covers the design topology of dynamic multipoint VPN (DMVPN).
This guide is part of an ongoing series that addresses VPN solutions, using the latest VPN technologies
from Cisco, and based on practical design principles that have been tested to scale.
The adaptive security appliance delivers unprecedented levels of defense against threats to the network
with deeper web inspection and flow-specific analysis, improved secure connectivity via end-point
security posture validation, and voice and video over VPN support. It also provides enhanced support
for intelligent information networks through improved network integration, resiliency, and scalability.
The adaptive security appliance software combines firewall, VPN concentrator, and intrusion prevention
software functionality into one software image.
Cisco enterprise customers have in the past relied heavily upon traditional WAN/MAN services for their
connectivity requirements. Layer 2 circuits based on TDM, Frame Relay, ATM, and SONET have
formed the mainstay of most low-speed WAN services. More recently, high-speed MAN solutions have
been delivered directly over Layer 1 optical circuits, SONET, or through the implementation of
point-to-point or point-to-multipoint Ethernet services delivered over one of these two technologies.
This book is designed to help you prepare for the Cisco SECUR certification exam. The SECUR
exam is the first in a series of five exams required for the Cisco Certified Security Professional
(CCSP) certification. This exam focuses on the application of security principles with regard to
Cisco IOS routers, switches, and virtual private network (VPN) devices.

IPSec—IP Security Protocol. IPSec is a framework of open standards that provides data
confidentiality, data integrity, and data authentication between participating peers. IPSec provides
these security services at the IP layer; it uses IKE to handle negotiation of protocols and algorithms
based on local policy and to generate the encryption and authentication keys to be used by IPSec.
IPSec can be used to protect one or more data flows between a pair of hosts, between a pair of
security gateways, or between a security gateway and a host....
