1. Introduction The Cisco 5540 Adaptive Security Appliance ASA is a best-of-breed product that provides perimeter security and remote access to users through VPN. This paper will discuss the firewall and VPN classifications and protocols of the Cisco 5540 ASA. The paper will discuss the strengths, weaknesses and effectiveness of the appliance and its architecture. 2. Cisco 5540 Adaptive Security Appliance ASA The Cisco 5540 ASA is a good blend of proven network security and network availability. The Cisco 5540 Adaptive Security Appliance ASA is a combined firewall and VPN solutions. The appliance is rated for small to medium size businesses and is designed for installation on the Internet edge (Cisco ASA 5500 Series Adaptive Security Appliances, n.d.). The appliance has optional modules that perform anti-virus and intrusion prevention services. 3. Technical Classifications and Specifications Firewall The Cisco 5540 ASA is classified as a transparent firewall. The ASA combines the best of packet filtering, screened host, dual-homed host and screened subnet firewalls into one product. The Cisco 5540 ASA has two firewall modes of operation (PIX/ASA Security Appliance FAQ, n.d.). Routed mode performs packet inspection and forwarding based on layer 3 or Network header information (PIX/ASA Security Appliance FAQ, n.d.). The preferred operational mode of the firewall is transparent mode in which the firewall operates as a layer 2 or data link bridge (PIX/ASA Security Appliance FAQ, n.d.). In transparent mode, the firewall can use an IP access lists and it can inspect IP activity at any layer (PIX/ASA Security Appliance FAQ, n.d.). The Cisco 5540 ASA allows network managers to segment traffic into security zones, i... ... middle of paper ... ...p://www.cisco.com/en/US/prod/collateral/vpndevc/ps6032/ps6094/ps6120/prod_brochure0900aecd80402ef4.html Cisco Intrusion Prevention System - Products & Services - Cisco Systems.

In order to protect the application servers from the internet, the most common un-trusted network, the proposal suggests a firewall to be installed between the internal network and external router. The firewall would be an Adaptive Security Appliance (ASA) firewall, "the ASA is not just a pure hardware firewall. In brief, the Cisco ASA is a security device that combines firewall, antivirus, intrusion prevention, and virtual private network (VPN) capabilities. It provides proactive
The goal of Clark Consulting remains to help develop a more secure network for Harry and Mae’s Inc. in that vein, Clark Consulting has determined some final additions and changes to the Harry and Mae’s Inc. network. The additions include a Bastion server, Network Intrusion Detection System (NIDS), Host Intrusion Detection System (HIDS) and a Security Information and Event Management (SIEM) server. The changes will primarily revolve around passwords.

VPN requires an in-depth understanding of public network security issues and proper deployment precautions. The task of choosing and deploying a VPN solution is far from being simple and may require the training of workers in at least the basics...
...vantage of the overall network design and implement usable subnets with virtual local area networks. Use encryption and encapsulation to secure communications of public segments to enable extranets and cross-Internet company traffic. Use items such as intrusion detection systems and firewalls to keep unauthorized users out and monitor activity. Taken together, these pieces can make a secure network that is efficient, manageable, and effective.
Although Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) have been grouped together here (IDPS), there are distinctions between them. On the most basic level, both will monitor the network...
Network management planning and security planning involves identifying the best and most appropriate systems and hardware that the firm can use to better manage network and plan security systems. Therefore, the management required me to examine the best software and hardware systems in the market place that the company can adopt to enable it to manage the network and security.

Without proper protection, any part of any network can be susceptible to attacks or unauthorized activity. Routers, switches, and hosts can all be violated by professional hackers, company competitors. In fact, according to several studies, more than half of all network attacks are waged internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, an...
This proposal is for a small office that will have users who are connected by Wi-Fi or cable. The network will include devices and resources that is shared among all the users. The network will need to have security measures in place to protect the entire network and keep the wireless access secure and available only to employees of the company.
