Building a secure network

SECURE INTERNET ACCESS TO GATEWAY USING SECURE SOCKET LAYER Internet has become the main medium to run distinct sites. The main issue in using internet for such sites is the security. There are many protocols invented to overcome this problem. This protocol provides the way to increase the security. The present paper provides the solution to the problem during the communication between the client and server.

Physical security, software and configuration for all aspects of the network design must be addressed in the security policy. Detailed plans for meeting the physical security requirements are paramount to achieve the creation of a secure network. The physical security for critical network assets must be adequate when compared to the severity of damages that a breach could cause. Integrity of construction, cypher locks, access cards, keypads, biometrics, cameras, and guards with access logs are all considerations that must be specified as appropriate for the network and the data which will be used on it. The level of clea... ... middle of paper ... ...and IPS they make the entire network more secure by adding more layers of security at the host to harden the security posture.

A remote network access policy would define appropriate standards to be applied in connecting to the company’s network while outlining the security standards that devices attempting to connect to the network would follow for successful connectivity. This paper outlines the various network security guidelines that are secure both for the users within an organization and for remote users as well while maintaining a high degree of reliability. Security in Network Management Network management processes that have the backing of senior management are paramount in ensuring that the organization develops security for its network. The management needs to play a great role and incorporate security guidance into their network. The network security guidelines provided here should govern how the network should operate in the area of security, how the network would be developed to maintain security, how security is organized to support upcoming needs, and how the network will comply with the operational and regulatory security needs (Gupta, Chandrashekhar, Sabnis, & Bastry, 2007).

TCP, or transmission control protocol, is one of the most fundamental aspects of guaranteed information transfer on the Internet. As the fourth layer in the OSI model, the TCP protocol ensures that all data sent from one IP address is, in fact, received by another IP address. If a packet did not make it the recipient IP, TCP would call for the packet to be sent again, until confirmation of reception. It is due to these reasons that TCP grants the user the capability of providing stream based transfer of data reliably. The Secure Socket Shell (SSH) is a UNX-based protocol allowing users to securely gain access to a remote computer.

Our team recommends the following course of action. Utilize a network architecture and topology that follows close to the following diagram (Diagram 1: Network Layout). The topology is a mixture of multiple star-ring networks. NAT would take place at the central firewall directly connected to the internet. This would allow the incoming and outgoing information to be sorted correctly and ensure that it reaches the correct destination.

Therefore most important thing to do protect computer networking. And the all the system is safe for all computers and the users within network.

Capable of carrying out registration packets and performing real-time traffic analysis on IP networks. Tool performs record-keeping, analysis, search for content, and is also used for blocking the active or passive attacks or echo’s, such as buffer overflows, stealth port scan, attacks on web application, SMB scanning and attempts to identify the OS. The software mainly used to prevent intrusion into the system and block attacks which may occur. As snort is based on the Open source code it is easy to configure software to any WLAN. Let’s note that Nowadays snort is one of the network software standards for intrusion detection system (IDS).

The hardware should be installed and configured first to enable the operating systems and software set up into the network systems. The operating system installed in the network systems should be considered as the main component of the network infrastructure. Therefore, the company should consider installing one type of operating systems, this because they have similar protocols thus the communication will be efficient. Similar operating system will enable network component to have seamless communication procedures between the components, therefore, if the company should adopt the latest windows 8, this is because the operating system have the latest standardization

Basically SSL provides security for web based applications like internet banking. For providing end-to-end secure service over TCP, we use SSL. SSL is basically divided into two layers of protocol. Bottom layer is SSL record protocol which is used by HTTP protocol.
