fundamental reason why security protocols are implemented in networks is simple – to protect data as it traverses the network. The mechanism associated with protecting data on its travels is called cryptography. This particular mechanism employs algorithms which encrypt data so that hackers are prevented from easily intercepting the data. Cryptography operates in tandem with a group of protocols which help to control the passing of data between network devices. Therefore, security protocols are a vital
work on the data link layer of the OSI Model. However, switches are more advanced. Discuss how a switch has an advantage over a bridge in a network then elaborate more on the technology implemented in switches to control broadcast domains (500 words). [25 marks] There are many reasons why switchers are used instead of bridges. The switchers nowadays are more effective than a bridge when are used in a network. Bridges, also known as transparent bridges, work in the Layer number 2 of the OSI model

Hardware, software and the data that resides in and among computer systems must be protected against security threats that exploit vulnerabilities. Organizations must therefore impose appropriate controls to monitor for, deter and prevent security breaches. Three areas have been considered, in a typical sense, as the basic critical security requirements for data protection: confidentiality is used to assure privacy; principles of integrity assure systems are changed in accordance with authorized
protection” to just about every door on earth. That’s the magnitude of security problem posed by the Heartbleed Bug,” says Kevin Morris from the Electronics Engineering Journal (April 15, 2014). Heartbleed is a “security vulnerability uncovered in April 2014 that allows hackers to gain access to passwords and personal information,” states the Encyclopedia of Technology. This OpenSSL security flaw was discovered by the Finnish Network Security Firm, Codenomicon. It allowed for the extraction of information
Part 4: Possible Solution and Prevention for Pharming 1. Use SSL (Secure Sockets Layer) Certificate in Authentication A SSL certificate can help prevent Internet users from being victimized by pharming attack when they attempt to visit a Web site. It is a digital certificate that authenticates the identity of a Web site to visiting browsers and encrypts information for the server via SSL technology. In other words, it is like a unique fingerprint or passport that identifies a legitimate

Under 'Files' enable 'show relative path' this is a security issue. A FTP client will now not be able to see the ENTIRE path of the FTP.
become located in more and more locations so there are more potential weaklings to exploit in to it. Body To defend this, the principle of layer security is still a choice. It is the application that run the business and that’s why there is a good mix between traditional tool and modern technology being applied in this area. When applying the layer of security, usually people make it based on risk, applying the highest level of protection to the most risky and most risky and valuable application.

## Introduction This article explains how to install and configure a multi-protocol VPN server using the SoftEther package. We enable and configure OpenVPN, L2TP over IPSec and SSTP VPN Servers on Linux. ## What is SoftEther SoftEther VPN is one of the world's most powerful and easy-to-use multi-protocol VPN software made by the good folks at University of Tsukuba, Japan. It runs on Windows, Linux, Mac, FreeBSD and Solaris and is freeware and open-source. You can use SoftEther for any personal
Computer has brought about amazing revolution in the life around in the present day world. Its use, now it so seems, has become a necessity, and has created for itself indispensability. Internet has transformed the life and information technology. It is a melting pot of so many technologies which provides multi-media information facilities at low cost and great speed. The approaching trend on the internet now is online shopping. It is a process in which one can buy or sell items online via the internet
the consumer to numerous threats with the largest being an insider threat from the OEM. Perhaps there is an unidentified intent behind this adware from Lenovo “… (only a dope would consider ad-injecting malware to be “value-add”)” but after the security vulnerability became known to Lenovo, the company should have deemed Superfish more trouble than it’s worth.” (Auerbach 2015) Why is Lenovo so persistent to use Superfish? Does Superfish have a stronghold influence over the Lenovo Corporation?
RosettaNet Implementation Framework (RNIF) The RosettaNet Implementation Framework, abbreviated as RNIF, defines implementation guidelines for creating software applications which allow reliable transport of PIPs in XML-format business documents between trading partners. RNIF is a robust routing, packaging and security standard created by the RosettaNett consortium to define the way in which a RosettaNet message must be transported, thus providing the underlying service protocol for implementing RosettaNet
communication between two end users. Seven different layers make up the OSI model: physical, data link, network, transport, session, presentation, and application. This paper will cover the type of security that is associated with each level of the OSI model. Physical Layer The physical layer is where the actual communication occurs between devices. The security of the physical layer pertains to the actual hardware. The vulnerabilities of the physical layer include: Power outage Environmental
OSI Model and Security The Open Systems Interconnection Model is a conceptual model describing how any combination of devices can are connected for the purpose of network communication and troubleshooting (Panko & Panko, 2015). Comparing the OSI model’s layers to the levels of application security will shed light on application vulnerabilities. Layer 1 of the OSI model is the Physical Layer. At this layer the OSI model focuses on wires, signals, and repeaters. The security threats are inadequate
ability to handle the routing of packets. However The TCP/IP stack consists of 5 layers first being application layer, the transport layer, then the network layer, the link layer and finally the physical layer. The assignment focuses on the three middle layers and is divided into five parts. Firstly explaining how the TCP and UDP the most vital protocols needed to deliver and communicate. Explain how the two important transport protocols deliver messages on behalf of the application and discuss the differences
Header (AH) and Encapsulating Security Payload (ESP) are a part of the IPSec components, they are network layer protocols allowing secured communications through a VPN tunnel. Within a firewall to enable communication for AH one will use protocol 50 and for ESP protocol 51 (Frankel, Hoffman, Orebaugh & Park, 2008), both protocols 50 and 51 can be enable within the same end-to-end IPSec connection which is the Tunnel Mode connected by two gateways. Nonetheless, for Transport Mode, there are some restrictions
Security and the OSI Model Network security is a topic that reaches far beyond the realm of firewalls, passwords, and user ID accounts. For a network and data to remain secure there must be protective measures at each level in the OSI interconnect model. While each layer basically operates autonomously of the other it is important to ensure that the data being transmitted from the host to destination has not been tampered with or is being prevented from reaching its destination. There are seven
WIMAX Security Issues Threats to The WIMAX Some of the WIMAX threats are: Rogue base stations, DoS attacks, Man-in-the-middle attacks, and Network manipulation with spoofed management frames, Threats in the physical layer. Rogue base stations It is defined as an attacker, which copies a legitimate base station. It allows hackers to confuse subscribers. WiMAX uses time division multiple access, thus the rogue base station must transfer with a stronger power at the same time the legitimate station
specific layers. Each layer performs specific tasks relative to achieving communication. This paper will address the layers by explaining what they do individually and how they work together as a whole. Each OSI layer labels the piece of data that it processes before passing it on to the next level. The next layer could be either above the current layer of below the current layer depending on whether the computer is receiving or sending data. For purposes of this paper, the layers will be
