Network topology

-

Two types of topology
- Physical topology
- Logical topology

 Point to point topology
-       Two host
-       Example Wi-Fi connect to router
   
     Diagram

BUS topology
-     
         All devices share single cable
-       Example 5 pc connected to 1 line, and if one part is broken than it is lagging

     Diagram













     Advantages it is simple and reliable, requires small amount of cable
     Disadvantages a cable problem can shutdown the entire network, troubleshooting problem is difficult to do


Star topology
Many devices are connected to only one hub or switch
Example 5 pc connected to 1 switch/router/hub
     Diagram




















Advantages
-       Disadvantages Expensive, more cable, If the switch is broken so there will be no connection
-       

Ring topology
-       Each computer connect to exactly two other machines
-       Using token ring

     Diagram






















-       Advantages Queue up send by one, If 1 part is broken, the pc is still connected, sending a message is faster because the cable is only use by the sender
-       Disadvantages Others can read by other devices, take time, privacy of the messages


Mesh topology
-       Computer is connected to one or multiple computer
Two types of mesh topology
-      Full mesh – All computer have a point to point, everyone is connected to one
        Partial mesh – Not all computer connected to each other

     Diagram
























-       Advantages Sending a message is faster and there are many ways to send message even if one cable is broken
-       Disadvantages Expensive, more cable

Tree topology
-       Known as hierarchical topology
-       Most Commonly use network topology

     Diagram










-       Advantages is fast, suitable for office , easy to identify when there is network failure
-       Disadvantages expensive

Describe the test and purpose of the test Log analysis is the term used for analysis of computer-generated records for helping organizations, businesses or networks in proactively and reactively mitigating different risks.  Log analysis helps in reducing problem diagnosis, resolution time and in effective management of applications and infrastructure. Checking all the log to find if there ordinary problem Discuss how it works Logs are usually created by network devices, applications, operating systems, and programmable or smart devices. They comprise of several messages that are chronologically arranged and stored on a disk, in files, or in an application like a log collector. Provide example Discuss the solution of there is vulnerability after a test If there is

1.        Business Continuance -           Business have come to recognize that some services of the organization have to be delivered continuously without interruption -           Create an IT Business Continuity plan( Backup business Plan) -           Focus on getting the network and systems up and running as quickly as possible. Business continuity and disaster recovery planning -           Management leadership, goals and requirements, business impact analysis, team building and implementation Backup alternatives -           Hardware and software approaches, electronic vaulting Recovery and testing -           Strategies for executing recovery, carrying out drills and types of plan testing Emergency Response -           Preserving assets and life, reducing fraud, theft and vandalism 2.        Backup / Restoration of Data -           When we think of backup, we generally think of secure, offsite tape storage that will be available should we accide

Network planning - Proof of concept

-
How to design a secured network (methods, the steps) The different types of network security design that will aid good network security 1. Identify the assets such as hardware, software, employee 2. Identify the budget of the company 3. Analyze security risk with the solution (virus- install anti virus) 4. Analyze security requirements 5. List down all the software that can be installed in the network 6. List all the asset (Security hardware for example VPN, firewall, antivirus, DMZ) 7. Identify the secure connection (cable or wire) 8. Design or sketch a network 9. Ask other colleague or approval by the organization or the client An organizations need to update their system frequently, because hackers are discovering new flaws in security network and coming out with new methods to gains access to unauthorized networks. 1.     Network access control -        It is for controlling which users can access you network -        Identifying which users and devices a
