6. Network Security Policy A secure network infrastructure is needed to protect the integrity of data and mitigate risk of a security incident. The purpose of a specific network infrastructure security policy is to establish the technical guidelines for IT security, and to communicate the controls necessary for a secure network infrastructure. This policy might include specific procedures around device passwords, logs, firewalls, networked hardware, and/or security testing. 7. Internet Use The

1.1 Critically evaluate the different LAN technologies like Ethernet WLAN using 802 or 802.11 wireless standards that are meeting the client based requirements and identify the requirement that will be used in each technology. How Ethernet transfers data on a network: – Carrier Sense Multiple Access with Collision Detection (CSMA/CD) – Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) • Both are contention-based access methods – Different nodes on the network segment compete to see

Those of you with an iPhone, iPad and iPod touch capable or running the original iOS 9 software release can now update to the latest iOS 9.0.2 software update manually using the IPSW files. The official release of iOS 9.0.2 arrived a few weeks ago now, but with the latest Pangu 9 jailbreak for iOS 9.0.2 just released, you might want the official iOS 9.0.2 IPSW files to download and install on your computer. The reason is that you should not install the Pangu 9 jailbreak on your device if you updated

having to wait until each person has finished speaking and stops sending data. Networking Components When creating a LAN network, there are many different components that are used, what components are used depends on the task that the LAN is setup for. A central hub would be used in larger LAN networks to join separate LAN’s together. When the hub receives a packet, it is then broadcast out to all of the connected devices. This may cause security issues as although each packet is closed with an

Fredrick Donaldson Nov.5, 2014 NT1110 Unit 5 Assignment 1 Video Summary 3 CPUs In today’s market there are 2 main manufacturers of CPUs: Intel and AMD. There are also some smaller competitors that manufacture CPUs, but they tend to come and go. The way a CPU is organized varies, but here are the basics: The motherboard system bus carries information into and out of the CPU. When the system bus enters the CPU, it’s called a Front side bus. The Front side bus usually uses a 64-bit wide data

2. Identified Risks There are a number of organisations that maintain a database of vulnerabilities. The list below is not exhaustive, but the vulnerabilities listed in this report have been extracted from Cve.mitre.org (n.d.). 2.1 The Catastrophic List These vulnerabilities were identified during the assessment and need urgent remediation as they pose a serious security risk to the organisation. ID Vulnerability Description Risk Category Remediation Method V001 A firewall is on the edge of the

Client-server architecture of a computer network in which many clients (remote processors) request and receive service from a centralized server (host computer). Client computers provide an interface to allow a computer user to request services of the server and to display the results the server returns. Servers wait for requests to arrive from clients and then respond to them. Ideally, a server provides a standardized transparent interface to clients so that clients need not be aware of the specifics

Identification- Richman needs to assign a unique identifier or password to the individual users; this will assist and have accurate record of the users on the network. With a unique identifier lots of data can be recorded and kept just incase something happens with the network Richman can know exactly when, where, and more details of how this incident transpired. Authorization- Richmann’s investments have to clarify and make known the rules as to who and what computers can gain access to the network

IV. Future trend The SDN network has been introduced a series of security checks, such as existing Intrusion Detection Systems and Intrusion Prevention Systems. As taking advantage of the decoupled data plane and control plane, the potential solution for the specific attack has been emerged and rapidly deployed. A.Virtual access point of edge For better security, we may want to transmit the cryptographic data through data plane. In order to separate the client device from encrypted data plane
