...1.1 VIRTUAL PRIVATE NETWORK: A VPN is a method to connect the office network (for example Private network) from the client systems (for example home Laptop) via public network (for example an Internet). A VPN tunnelling will have the advantages of dial-up connection to a dial-up server, because of the flexibility of an Internet connection and also the ease access of an Internet connection. By using an Internet connection the client can connect to the server or the resource in all over the world, like accessing the office desktop from home through an Internet connection. The computer and the office desktop can communicate at full Internet speed or very high speed if you have an Internet connection as cable or digital subscriber line (DSL). This type of connection works very fast...

...Stephy Stitt Firewall/VPN Project 1 August 24, 2014 There are a number of risks on our network. Those risks are data confidentiality, data access and network issues. Our network has a router/firewall configuration. All files are kept on the network. The network can be accessed from home. The computers in the lab have direct access to the internet. All of these can invite potential threats at any time. The network allows potential threats through a router/firewalled device. I am assuming that the firewall has been configured by a default means. This will give hackers the ability to exploit any open ports left open. There will also be the security hole of the router itself if the firewall has not been configured correctly. I am also assuming that the sysadmin passwords have not been changed from their default status. Second, all data is kept on the network. I am assuming that there is no centralized server or storage for this data. If the data were kept all over the place on workstations or some external drive then this will invite hackers to gain access to all of the data. There was also no mention of this data being secured by passwords or permissions. Third, the users can access the network from home. This is a huge risk. There is no mention of VPN or other means of secure network entry. There is also no mention that the user’s personal workstations are secure enough to be on the company network. It seems that they are able to remote to any workstation on the...

...Modern Day Attacks Against Firewalls and Virtual Private Networks Electronic technology is growing at a rapid rate; more devices are made mobile and wireless, but with those improvement and developments come flaws and malicious opportunities. Cyber attacks are on the rise and no system or device is immune. Many organizations employ multiple layers of firewalls but that doesn’t completely eliminate the threat. Attacks against firewalls and virtual private networks or VPNs are constantly being exploited with new methods everyday, but they are yet another obstacle that a cyber criminal must overcome. First let’s discuss what a firewall is and what a firewall is capable of doing. Firewall applications are normally used to protect and secure private networks. A network can have a software, hardware or both firewalls installed and they provide the “ability to control in-bound and outbound traffic”, according to Pirc of Sans Technology Institute (para 2, nd). Most Microsoft operating systems today come with a firewall installed and Microsoft suggests that you should have a firewall set up on each system in your home, even if you have a hardware firewall such as a router that has security policies adjusted, this can help prevent any malicious activity from spreading across your home network. Most firewalls contain a variety of policies but they all at the very least have the same basic policies that can be set up. There are 3 common policies that you...

...consisting of 50 total computers will be physically connected through a fiber line with a T-3 connection to the internet. The primary servers for this network will also be located at location 1. Location 2 and 3 will connect to the network via the VPN concentrators. Location 3 will house back-up servers for the network. Both locations will also connect to the internet with a T-3 connection. T-3 lines are a combination of 28 T-1 circuits and produce 44.736 Mbps of total bandwidth for the network. T-3 lines are commonly used for building a business network at one centralized location. Although T-3 line is costly, it is required for a large business network because of the speed and the amount of bandwidth it provides (Mitchell, n.d.). For location 2 and 3 to operate on the same network, VPN is a viable option. It provides an enhanced level of security, allows for users to access network assets, eliminates the need for distance leases lines, is cost effective, can offer better performance, provides online privacy, allows for remote access, and offers network performance efficiency ("8 advantages of using VPN - ibVPN.com," 2010). A VPN server will also allow for remote connectivity for employees to access network resources while away from the office (i.e. telecommuting). A primary server and a back-up server are included in this network. The backup server will be a Warm Backup Site. A warm backup site is typically pre-configured equipment but does not contain live data. In order...

...Best Practices for Network Security DaMarcus Forney American Military University June 19, 2013 Best Practices for Network Security It's no secret that there are millions of networks around the world. Today, networks are relatively easy to create. A network can be something as simple as two computers or hosts being connected together. They can also be very complex and consists of thousands of different network objects such as routers, servers, printers, and workstations. The Internet has revolutionized the way networks can be used. It has created endless possibilities for network technology as a whole and it's users. The first networks were intranet networks. All of the objects running on a intranet, including the infrastructure itself were locally owned and managed. As more and more information was being stored on intranets the need to secure them became more important. The good thing about intranets is that majority of the threats associated with them are internal, making them easy to secure. This can not be said about external networks such as the Internet. The Internet introduced threats that can reside from anywhere in the world. This put greater focus on network security. Securing networks that have access to the Internet is a never ending job. The sad part about securing a network is that a network will never be 100 percent secure. There will always be risks associated with every type of network. One can reduce those risks...

...The Tools of Network Security Name Date Class Professor School Introduction Network security can be hard in the environment of constantly changing technology. Strong protection does not have one simple solution. Anyone who is concerned with the protection of their computer, data, or network needs to be ready to spend time researching their specific needs to protect all the different layers and domains that can be attacked. The areas that need the most attention are port scanning, protocol analysis, vulnerability tests, intrusion prevention, firewall use, VPN security, internet filtering, and password recovery. Users need to become proactive when it comes to their network’s security by knowing what tools are the best for the job and being able to implement these tools quickly and correctly. Port Scanning Port scanning and IP scanning is an important step towards network security. A port scanner checks for available virtual ports on your network and can identify if they are open or closed. Finding out which ports are open allows network administrators to take appropriate protective actions by closing or blocking traffic to and from those open (Network Security Tools, 2013). Nmap is the major tool of choice for most network administrators. It is an affordable choice because it is a free open source tool. Nmap supports most operating systems and comes in wither a traditional command line interface or GUI version (Nmap, 2013). Nmap works by using raw IP packets...

...IS 3220 IT Infrastructure Security Project Part 1: Network Survey Project Part 2: Network Design Project Part 3: Network Security Plan ITT Technical Institute 8/4/15 Project Part 1: Network Survey Network Design and Plan Executive Summary: We have been engaged in business for some time, and have been very successful, however we need to re-examine our network configuration and infrastructure and identify that our network defenses are still reliable, before we make any changes. We need to take a hard look at our current configuration of host, services and our protocols within our organization. Data from a large number of penetration tests in recent years show most corporate networks share common vulnerabilities. Many of these problems could be mitigated by appropriate education in “hacker thinking” for technical staff. We will take a look at our security on routers and switches to make sure there are no leakages of data traffic. OBJECTIVE We have identified that we have loss some major accounts to competitors whose bids have been accurately just under our bid offers by exact amounts. We also believe due to shared reporting and public Web site functions that our Web servers have been compromised and our RFP documents have been leaked to competitors which enabled them to under bid us. We want to mitigate Web threats in the future; we realize the web is a mission critical business tool. We want to purchase new products and services, that will give us an edge and better...

Introduction Access control mechanisms operate at a number of levels in a system, from applications down through the operating system to the hardware. Higher-level mechanisms can be more expressive, but also tend to be more vulnerable to attack, for a variety of reasons ranging from intrinsic complexity to implementer skill levels. Most attacks involve the opportunistic exploitation of bugs; and software that is very large, very widely used, or both (as with operating systems) is particularly likely to have security bugs found and publicized. Operating systems are also vulnerable to environmental changes that undermine the assumptions used in their design. The main function of access control in computer operating systems is to limit the damage that can be done by particular groups, users, and programs...
