Understanding Cybersecurity Insurance Insurance For Computer / Internet 2015

On this occasion, meetcrack will review the definition of Insurance Cybersecurity, which is an insurance product that is devoted to reducing the harm caused by cyber crime. The main technological world as the development of the Internet is very sharp and impact - the impact was not only positive but also prone to the negative impacts. One of the negative impacts of the most feared by the business community is the cyber crime.

What's Cyber Crime?

Cybercrime (cybercrime) an act of abuse of or opposition to the law by utilizing the computer as a tool to do so, once this action is done especially with the widespread availability of Internet access that is easy and inexpensive, so it can trigger behaviors that are very harmful to others. with the Insurance Cybersecurity, businesses that utilize computer technology is Ter Bantu Kan. how, cool right?

Understanding Cyber Insurance

Insurance Cybersecurity is designed to be able to minimize losses caused by cyber events, including business interruption, data breaches, or it could be because it caused damage to the tissue. but not many companies engaged in insurance which provides insurance products Cybersecurity. it dies EB Akan because of the difficulty of determining insurance premiums Cyber own. many questions which arise due to uncertainty as to whether the organization making the insurance will experience an attack or not, until - until an association of America - NAIC (National Association of Insurance Commissioners) strongly recommends to the provider of Insurance to review the potential customers, whether an organization or company that has done some mitigation of risk, one example is installing a firewall, anti-virus, and others.
In America Insurance Cyber, not a new thing, this is because the level of risk of cybercrime is very high, but in contrast to the state - a country in Europe that development is not like in America, but we can be sure the next countries - countries in Europe will also point in that direction, because of rising levels of cyber crime that occurred in the country - European country.
Some leaders of IT in Indonesia exposes the importance of Insurance Cyber to reduce the risk of crime in cyberspace, and to Indonesia itself is difficult to promote insurance products Cyber, this is because the level of cyber crime in Indonesia is still high compared with the country - the country abroad , but did not rule out some insurance companies have made a run - off to lead in this direction. it is not easy to calculate how this insurance can run as well as Life Insurance and Export - Import, due to the development of computer technology itself very quickly. and to learn about the reference that will be used as a determinant of Cyber insurance products, in the field of computer science or IT is not enough, so some insurance companies re-think again how to provide this Cyber insurance products.

Cyber Insurance Providers

While this is a company that provides insurance package Cyber is (AGCS) Allianz Global Corporate & Speciality, which is a state company from Germany with the title as the largest financial services company to 25 by Forbes magazine. risks that can be addressed by a package of Allianz's insurance as the hacking attacks that impact production stopped within a few days, or if it is found the company's reputation associated with the contamination of the other party using IT technology media.
The company dared to offer insurance products Cyber scandal since the incidence of leakage of State secrets by Edward Snowden. not only that the company engaged in due Game "SONY", also suffered a loss that is more severe, with the incidence of data breaches online portal "Playstation 3" that led to the theft of data - personal data and credit card members.
Products from Allianz not only cope with losses caused by attacks from outside but can also cope with the losses caused by their own customers, as only losses caused by the lack of skilled workers in the IT field. causing congestion within the system for days - days. Another example is when there is an important data storage company in "Cloud Computing" then the data - data that is stored is not accessible, the company can guarantee to replace the collateral that has been promised by the Cloud Computing provider.
For the high premium offerings from each - each company that will ensure the security of the computer is different, it is influenced by how big the company is and how big is also a system that will be secured. but companies such as banks still have not been touched by this insurance. because of possible insurance products is still fairly new, and really need to study the existing system in the banking world.
That review on Understanding Cybersecurity Insurance For Computer / Internet may review the above can increase knowledge and information for all computer pal.

Understanding Processor, Function and Type - Kind 2015

Processor, I'm sure of most pal computer must already know what the processor, but for those who do not know what the processor, I will now review a little of the processor and the type - the type of processor, the processor typically is often also referred to as the brain of the computer and the central controller, wherein his work will be supported by many components - components such as motherboards, memory, and component - component another computer. The processor can also be interpreted as an IC that is useful for controlling a computer system that runs and is used as the brains of the computer itself, as a working mechanism processor duty to perform calculations and execute commands - commands fed.
Basically, the function of the processor is just a tool that is used to process the data arithmetically. like, like a calculator, where he serves only to process the data that he received through the input or the input and then, he will produce output or output. any incoming data will run through the processor, then processed therein and outputs the resulting form of data desired by the user. not as we imagined, in principle machine language processor recognizes only the numbers 0 and 1.
Processor usually located in motherboards and placed on a socket that has been provided, a component of the computer which can be replaced with the type - the type of the other but must match the socket located on the motherboard. Processor meme puny ai enormous influence on the speed of the computer process is done, it is influenced by the type and capacity of the processor itself.

Computer Network Topology Model Frequently Used 2015

As we discussed earlier in the article  Definition, Function And Types of Computer Networks, that computer networks are divided into several types, and for the type of network based on the topology can be divided into several models of network topologies  include Ring topology, bus topology, Topology Star, Mesh Topology and Topology Tree. and on this occasion will top computers further review into 5 types of computer networks Based on the topology, if my friend had not understood about the topology should not we start out by knowing what the network topology

Understanding Network Topology

Computer network topology is a concept or method that is used to connect two or more computers into a network of inter-connected. Each model of the network topology itself will have other differences between the difference in terms of cost to make, the speed of transferring data and also in terms of ease of manufacture and maintenance nyah. of understanding if my friend had a computer to build a computer network, pal can determine the topology model which can mate later use.

Various - Various Computer Network Topology Frequently Used

1. Bus Topology

In the bus topology model of a computer connected to a network to be neatly arranged as a queue associated with a coaxial cable and BNC connector, then the end of the network using a terminator as the closing device.

The following Image of Topology B us

Advantages and Disadvantages of Computer Network Topology Bus

The advantages of the bus topology are to make it very easy, but it costs that are used to create a network with a bus topology is very cheap.
Shortage of bus topology is that if there is a problem or there is interference on one computer, then all the computers connected to this network will also be affected, in addition to the topology is also commonly found the problem that caused the data queue. and ap Abi law used to remotely this topology must be equipped with a Repeater to menu bug Kanya.

2. Topology Ring

In the model of ring topology each computer will be connected with other computer continuously and then connect it to the computer first, so that the network model will form a circle or ring, this topology using coaxial cable and BNC connectors, to be able to communicate this topology uses data token which is used as a controller computer access privileges for receiving data transmitted. for example, if the computer 1 will transmit data to the computer 3, the data sent will pass the second computer and then the computer 3, if the IP Andress destination computer does not match then the data will be forwarded to the destination IP address matching.

The following Image of Topology Ring

Ring Topology

Advantages and Disadvantages of Computer Network Topology Ring

The advantages of the model ring topology is the ease in terms Pemba Tanya, not only that this topology can avoid collisions of data files that are sent from each - each computer, in addition to the terms of use of the number of LAN cable, this topology can also be said to be efficient so as to reduce the cost of manufacture, the status of the computer connected to this ring topology is the same.
A shortage of models ring topology is, if one of the cables connected computer or on the network has an error then all the data transmission process in the network will be disrupted. besides the difficulty of the development of the model topology ring toward a broader also become one of the shortcomings of this topology model.

3. Star Topology

Network topology model this one is very unique because it forms like a star. To be able to connect one computer to another computer, this topology requires the hub or switch and cables used are equipped with cable UTP RJ45 connector types. Perngakat hub or switch duty to control the data and to be the center of this network. so if there is the transmission of data from one computer to the computer to 2, then the hub or switch that determines which computer IP that will be addressed without passing through other computers. today topology is most commonly used because many Kele BiH Anya than model Bus and Ring network topology.

The following Image of Star Topology

Advantages and Disadvantages of Computer Network Topology Star

Excess star topology is the topology is very flexible and to detect if an interruption occurs on a computer connected to a network, network control can be done very easily, and also when we will add or subtract the computer also will not have trouble. the star network topology model also has a level of data security is higher than with other network topology model.
Shortage of star topology is to build this network, we require a high cost, because the model of this topology requires a lot of wires and procurement switch / hub, the topology is highly dependent on the switch / hub of the factor of stability, so that if a component switches or hubs are damaged or interference then the entire network will also be impaired.

4. Mesh Topology

In the mesh topology to connect computers to each other can use a single cable, so in the process of sending data from one computer to the other computer will be able to directly reach the destination computer without passing through another computer or passing through the switch / hub.

The following Image of Mesh Topology

Advantages and Disadvantages of Computer Network Topology Mesh

The advantages of the mesh topology are in the process of sending data from one computer to the destination computer that can be done more quickly without going through a computer other than that, if there is damage to one of the computers, the other computers will not be disturbed or having problems too
Disadvantages of a mesh topology in terms of cost this topology is obviously going to take a lot of costs because of the need for cables that very much and also on each computer must have a Port I / O are also very much anyway, in addition to making this network topology installation process is also very complicated ,

 5. Topology Tree

Model of the network topology tree or tree topology is commonly called a combination of several star topology that connecting it to the bus topology, star topology so each will be connected to the other by using a star topology bus topology. This topology usually has several levels of the network, and a network that has a higher-level position can control the network that has a lower position ting katana.

The following Image of Topology Tree

Advantages and Disadvantages of Topology Tree

  • The advantages of the tree topology are ap Abi law we find fault and will also make changes to the network, then we can do it easily.
  • Disadvantages of tree topology are to build a model of the network topology it cost a lot because of the need for cables, a component and connector that much. in addition to the type of topology is also frequent collisions and slow connection, not only is it in the event of a network error on a high level, it can disrupt the low-level network.
That review on models of computer network topology that is often used in network technology world may be beneficial for all computer pal.

Definition and Types - Types Server in the Computer World 2015

On this occasion, Top computers will review the Definition and Types - Types of Computer Servers in the World. already heard what a computer server and what the function of the server computer itself?. for my friend who has been in the computer world computer network must already know and are able to describe these questions, but for those who still lay out the following reviews pal hopefully can increase knowledge about the world of computer networks. ok we just on the topic of problems.

Understanding Computer Server


Computer server is a computer that is designed specifically in terms of both hardware and software terms that are used as a service provider to the need for a client computer requests a network. Usually the server computer has an important task in computer networks as data traffic as well as resource provider for use by the computer - the client computer.
To meet such demand, computer server itself is required to have high hardware specs than the computer - the client computer such as processor speed, hard drive capacity and also the size of the memory used. Not only that, the software used must have features - special features and is also resistant to attack, either from within or from outside the network of networks.

Server Operating Systems

To support the performance of a computer server then takes a special operating system that is designed for the server, below are some examples of server operating systems are typically used in a network.

1. Windows

Microsoft company has several products that are dikususkan for server operating systems. some of the products are Windows NT, Windows 2000 Server, Windows 2003 Server, the Windows 2008 server and Windows Server 2013

2. Novel Netware

Novel Netware server operating system is an operating system developed by Novel.Inc some product is NetWare 286 2.x, NetWare 3.x,NetWare 4.x, NetWare 5.x, NetWare 6.0, NetWare 6.5 and Open Enterprise Server

3. Mac OS

Mac Os is a flagship product of Apple.Inc. Apple itself also has a product server operating system, beberpa example of a product from Apple is the Mac OS X Server 1.0 (Rhapsody), Mac OS X Server 10.0 (Cheetah Server), Mac OS X Server 10.1 (Puma Server), Mac OS X Server 10.2(Jaguar Server), Mac OS X Server 10.3 (Panther Server), Mac OS X Server 10.4 (Tiger Server), Mac OS X Server 10.5 (Leopard Server), Mac OS X Server 10.6 (Snow Leopard Server), Mac OS X 10.7 (Lion Server), OS X 10.8 (Mountain Lion Server), OS X 10.9 (Mavericks Server) andOS X 10:10 (Yosemite Server 4.0)

4. Linux

Products Linux servers are very diverse, because every developer providing products that dikususkan for servers, so here only mentioned developer of Linux-based operating systems only. multiple instances of Linux distributions that can mate use for servers is Debian, Arch Linux, Fedora, OpenSUSE, Slackware, and many others.
That is some kind of operating system that can mate use to build a server.

Macam - Macam Type Server

Computer servers themselves are actually several types and differentiated based on the function of the server itself, below are several types of servers are widely used in a computer network.

1. SSH Server (Secure Shen)

SSH Server is a server computer installed a specific application so that we can control or sending an execution order to the server remotely (remote). SSH applications typically use standard port 21.

2. DNS (Domain Name System)

DNS Server is a server installed an application in order to be able to function to translate a domain name into an IP address, so my friend does not need to remember the IP number of a computer, please remember domain name of the computer. DNS servers typically use port 53 to apply.

3. WEB Server

Web Server is a server computer that is equipped with a special application that can be used to serve requests HTTP / HTTPS from the client computer and sends back the data requested in the form of document html (web), web servers can also be defined as a computer that works to save the file - file web page. Web servers typically use port 80 to access using the http protocol and port 443 for access using the https protocol.

4. DHCP Server (Dynamic Host Configuration Protocol)

A computer servers with special applications and functions to memanagement allocation of IP addresses in a network. Given this server my friend does not need to perform charging IP address on each - each client computer, because it will be assigned automatically by the server.Ports used for DHCP is port 67 or 68.

5. Mail Server

Is a server computer that is equipped with an application that serves to distribute files - files or data or information in response to a request that will be sent via email, also in Bitnet for services such as FTP (File Transfer Protocol). Ports used for Mail Server is a 110 (IMAP), 143 (POP), 25, 2525 (SMTP) to access the http protocol, 993 (IMAP), 995 (POP), 465 (SMTP) to access the https protocol.

6. Proxy Server

Proxy server is a computer or a computer application that has the function to connect a computer in a LAN network with the Internet network.Proxy servers can also be referred to as the Gateway server or a gateway that connects the local network to the outside network. Not only that, this server also has the ability to securty and penyimpana history of web pages visited my friend who had been before, so it will save bandwidth usage later. port usually used for proxy servers is port 8080.

7. Samba Server

Is a server computer equipped with an application and functions to serve the demand sharing or exchange of data between two different client computer operating system eg Linux and Ms. WIndows. Ports used for Samba Server is 137 and 139.

8. FTP Server

A computer server used for file sharing or exchange of data on the network server or client that supports TCP / IP. the port used to transfer data using FTP protocol is port 21.

9. Database Server

The database server is a computer and comes with an application that serves to provide storage services database. the port used for the Database Server usually 3306 (MySQL) and 5432 (pgsql).

Caring for Computer Servers

Because the server computer has the task of fairly heavy and usually work for 24 hours nonstop. When my friend to be a server administrator, Computer Servers care is a matter that should not be disepelahkan, the following are tips that can mate employ to care for Computer Servers for optimum performance.
1. Clean regularly from dust and dirt.
2. Pay attention to the function of the software - the software from the server itself, especially security-related software.
3. Perform data backup and file defragmentation regularly at least once a week my friend did.
That review on the definition, of sorts - types and functions of server computers as well as tips on caring for servers that utopicomputers share, may be useful to review before a computer buddy as well.
