In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in†¦show more content†¦Security protocols are primarily commonly used to protect communication via the web, VPNs (Virtual Private Networks) and the transferring of files. This report will now go on to compare two main security protocols – TLS SSH. They will be compared in a way that takes into account both the similarities and differences in approach and features and their relative advantages and disadvantages. This information will then be backed up by examples where each protocol would be preferred to the other in a certain situation along with my own personal reasoning based on the research that has been carried out on my part. What Is TLS? TLS (Transport Layer Security) is the successor to another security protocol; SSL (Secure Sockets Layer) which was originally developed by ‘Netscape’ (HowStuffWorks SSL and TLS. 2014). It is a cryptographic security protocol which was designed primarily to ensure communication security across the internet. Communication security is achieved by the use of X.509 certificates and hence asymmetric cryptography which allows the exchange of a symmetric key, which can then be used to encrypt the data that is being transmitted between both parties involved in the communication. The protocol is made up of two main layers; TLS Record Protocol and TLS Handshake Protocol. TLS will be most commonly recognised when ‘https’ is noticed inShow MoreRelatedNetwork Security Enhancement Using Software Defined Networking Technologies1810 Words   |  8 Pages â€Æ' Network Security enhancement using Software Defined Networking Technologies Software Defined Networking (SDN) is a pattern of new technologies for permitting more prominent control of how networks work. As opposed to a genuinely static network that must be controlled by exclusive merchant particular protocols, with at times restricted deceivability into the internals of layer 2 gadgets like switches, SDN considers experimentation in enhancing and arranging how the network functions. FurthermoreRead MoreTechnological Advancements for Mabuhay Airlines 706 Words   |  3 Pagessmall airline company providing direct flight from Manila, Philippines to all points of the country.

It is because of these threats that companies create and enforce network security policies. A network security policy is a document that states how company intends to protect the company’s physical and information technology assets. (Rouse, 2007) A security policy is intended to be a living document thatRead MoreBest Practices For Network Security2439 Words   |  10 PagesBest Practices for Network Security Network security, in this technological age, should be one of the most important items of concern for any business owner or network administrator. Since just about every company out there is connected to and conducts some sort of business over the Internet, just about every one of them is at risk from outside threats. This means that they should take certain steps in order for them for them to conduct their business securely.

Not only is the end user accessing your network resources and potentially sensitive data, but they are many times doing so from a public network which the admin has no control over and is open to others who may have malicious intent. These connections clearly need to be properly secured in order provide end users secure network connections. To secure remote connections, a virtual private network (VPN) will created using the Routing andRead MoreEssay on Security Issues of Ambient Networks2196 Words   |  9 PagesIn this essay we will present security issues of a networking concept referred to as ambient networks, which aims to enable the cooperation of heterogeneous networks belonging to different operator or technology domains. In this way, it appears as homogeneous to the users of the network services. Providing security in ambient networks is a huge challenge. The main reason is that the traditional security model is not valid anymore. Traditional security assumes that there is a vulnerable channel
