Security is a multifaceted issue that must be addressed to avoid abuse of your network from hackers and employees. While you are connected to the Internet your network is open to the public unless it is protected by a firewall. Networks that are connected to the Internet are vulnerable to malicious attacks from hackers and virus infection. A well configured firewall will block uninvited visitors whilst allowing remote access to authorised users and services. Many firewalls now offer a host of other advanced features such as gateway antivirus, spam filtering, content filtering and the ability to block specific applications such as instant messaging to add further protection and restrict how the Internet is used within the office. Internally, sensitive information such as personnel records, management reports and accounts data can be protected by configuring permissions that only allow access for those who are authorised. Passwords to access the network should be changed on a regular basis and should be sufficiently complex that they cannot be compromised. We can advise on all aspects of network security, firewalls, virus protection and implement a security policy to protect your data and systems.
Not to be confused with the remote control we use on our televisions, remote control software, also known as Remote Desktop Software or remote access software, allows a computer or internet enabled device to be accessed and controlled by a second computer or internet enabled device. This means that an iPhone user could easily log onto a (consenting) friend’s computer, take full control of their machine, and use it to access the web, play a game, or do any of a host of other things. The beauty of these products is that distance makes no difference to the quality of the connection. A user in Ireland may just as easily take control of a computer in the United States as they would one in the very next room. Some people use this software to look in on the security of their home or the safety of their pets while at work or on vacation. Others find the direct technical support these programs facilitate to be more in line with their needs. From the practical to the novel, there is certainly no shortage of applications for these remote access products. In this article we will take a closer look at how remote control software can be used to help people learn how to use computers, navigate the web and further their skills on certain programs. Let’s say a close friend of yours is a few years behind the times. They have finally decided to buy their first computer, but have very little working knowledge of them. This is where Remote Control Software comes in. Once you get past the initial step of guiding them through the installation and setup of the software, it becomes a very simple process – simply connect..and you’re done! Many find that the best way to utilize remote control software for these types of lessons is to simply ask the inexperienced user to complete a basic task, such as sending an email, and watch how they go about it via the remote connection. As soon as they go off the path or begin to make mistakes, you can easily take control for them and show them where they went wrong. This method of learning is very powerful and effective. Lessons learned in this manner have a stronger chance of sticking into long term memory, as there is a visual action and an instruction involved in the learning process. This software can also be used to teach the more advanced user. A difficult to master program such as Adobe Photoshop can present a challenge to even the most experienced and savvy user. By making a remote connection with a Photoshop expert, advanced techniques can be exchanged and learned. Rather than struggling through a tutorial or online guide, a direct connection that allows for interactivity and dynamic input is the smart alternative. Using Remote Access connections to learn these types of techniques can be extremely advantageous when considering the amount of money, time and frustration that can be saved. If you have a friend or family member that can use your help with a computer based application, tell them to load up some remote control software so you can teach them in a manner that will truly contribute to their skill set and help them to effectively assimilate the information.

1. Who is the savior Have seen the “Matrix” series, a friend will not feel strange hero Ronaldinho, who broke into the virtual world of the programmer again and again interpreted the “savior” role, to protect the urban population, its image mammoth. Left Film After the majority of computer users we have to face is another Yizhenyijia digital virtual world?? Network, where many of the same latent danger, there is also “The Matrix”, but have not Antonio this person presence, we can see, the only kinds of Security Manufacturers and they offer security tools, in addition, seems to have no other choice. Consequently, many users of various security tools to look into the world of “savior”, we see a lot of security tools Advertisement We buy popular anti-virus software market, once a week we heard the “new virus warning” hurry to upgrade when the virus signatures database, we have every week on Computer For a long virus scan … … many people do, many people have to do this, because we put all that to the anti-virus tools, we need to do nothing, we simply wanton look online chat Movie next software, because we have anti-virus tools are available a “real-time monitoring” function, it will check every moment we have just download the file, and we feel very safe, we think this is network defense. But is this really so beautiful it? Vaguely remember that word seems to say so, “no matter what you do, you inevitably have to pay a certain price,” we are complacent in the enjoyment of security brought by the antivirus defense tool, we also pay the corresponding cost. Why? Because the removal tool is a time when the system starts to shut down or start to run until the time when the user exits it will stop running programs, their efficiency of detection and defense mechanisms and Ronaldinho can not be compared. Here is a simple example, people who learned about programming knows, is the most difficult chess program written in perfect, because the moves of chess has never been a fixed pattern, we can create a lot of tricks, but the program can not, it only judge in accordance with the limited mechanisms to determine how to get every move, which is why many of today’s chess programs look like a fool reason. Some people might say, to make a strong chess program to take the law are met as far as possible be included in the family to stay, and the chess program necessarily invincible. This is feasible, but the resulting price is per person, and it may have to spend playing chess lifetime, because the chess program at each step until all possible, should the circumstances encountered ” thinking “again, this time as to pay the price, if you want to shorten the time, we must think at the same time to process a variety of moves, but with time, the price becomes a huge drain on system resources?? you can bear Why? The same defects are antivirus software happen, we know that most antivirus software is a “signature” technology to search for the virus, that is, anti-virus software engine reads the contents of a program or file, and with own database stored procedures have been identified as virus-specific code to match a certain body, if they are the same, anti-virus software on the “confirm” this file as a virus. With a large virus family, the database size growth to the point can not be ignored, also slow the speed of loading. And each additional virus signatures database, anti-virus engine would increase the branch of a judge, the time will be extended accordingly, in order to avoid the need to scan a document the embarrassment of a half-hour, anti-virus software will use a variety of programs to improve the matching speed However, without exception, these programs must be crazy exploitation of the user’s system resources, if a computer’s configuration is not very high, then the user check narcotics, he basically can not do other work properly, and find TV station Slowly watching TV dramas it, this is the Neo price. So who is our Saviour? The answer is?? You. Can never trust only themselves, if you work hard, everyone can do Ronaldinho, but this is a cost, because it changed the consumption of system resources consumption of the brain, to determine branch and experience to write my mind, efficiency in dealing with the branch, the people will never be flexible than the procedure, but this way will not be dependent on the vicious Cycle , And left the anti-virus software, we have to learn on their own to protect themselves from the virtual world of hurt. Now, let us do it their savior. 2. To do your own savior Child had seen a story, “another aggression” of the human space invaders defeated a kind gift of human Crystal As long as human took it like a kind items, the item will appear in front of their own, so everyone has been immersed in the endless enjoyment in, no one was to delve into science and technology of national defense, and several decades later, the human began to emerge degradation. This time, the universe again visit the earth invaders, this time they only used a whip on the conquered article, the last man into the cage before being expelled, he turned around and said something vague words?? Even his tongue was almost degraded, perhaps he said: “The earth finished.” Story may only be nothing more than fantasy, but it is similar to the behavior of contemporary place, if a user suspect their computer infected with a back door, his first reaction will probably open the removal tool. Too dependent on the human story of the magic crystal, in reality we are too dependent on convenient and efficient anti-virus software! One may object, as convenient to use the tools to protect computer security, why should I bother to learn security defense? So the user does not want to think of the complexity of the network can break into the computer’s “guest” is not a major security tool vendors wanted list of members, as part of the network is also popular with small-scale use and has not been made public, “private back door “(for example most of the DDoS tools are actually the back door to write their own use), the ability of people can write their own” private back door “, and then put through a variety of ways the implementation of someone else’s computer. At this time, “the virus signature database” technology began to reveal the limitations of being infected with the “private back door” of the user I am China Manufacturers writer, reports some information about blue camisoles , knit boxers.
Suppose that you are appointed to lead a project of a computer network design in your organization that contains many sites that need to be integrated into a single corporate private network, what are you going to do? As a team leader, a time-frame project as general needs to be developed first that includes the brainstorming to collect data as much as possible, the blueprint project, budget forecasting, liaising with the third parties and so on. It’s quite difficult to start a project properly without knowing exactly what the strengths and weaknesses of supporting infrastructure which the system will base on. It is therefore, a computer network design should start by brainstorming to collect data as much as possible. Assume this computer network design will involve three sites: one main headquarter office in Sydney, one main office in Jakarta, and one remote site – the gold mine in the middle of the Borneo jungle. The principal of the organization would like to have all the sites linked to a single corporate computer network to allow inter-sites communication including data, voice, or probably video conference and off course to allow easy communication with the whole world. Telecommunication Requirements The first data for your computer network design that needs to be collected is the telecommunication system requirements. The main question is how to link all of the sites to allow system communication to happen. The following questions can be used to collect the data for the telecommunication requirements. 1. How to arrange the Telecommunication service in remote site? We understand that both the main offices in Sydney and Jakarta are located in the area where you can find lots of communication services. What about the remote site – the site in the middle of the jungle? You should liaise with the third party company that can provide WAN services technology – probably uses the satellite link communication. 2. Collect the information what kinds of communication will be allowed for remote site to the Jakarta office: data only, voice, video, or combination of those. This information is important to help you determine how wide the satellite link bandwidth you need. This will relate to the budget since satellite link is expensive. 3. What kind of WAN technology to link data between Jakarta and Sydney, frame relay, ISDN network, VPN connection? Liaising with the third party – the telecommunication company will help. You need to dig and find more data that specific to the project. Telecommunication requirements should be sorted out first before you can proceed to collect other infrastructure requirements in this case. Network Infrastructure Requirements Second requirement for your computer network design is to collect data regarding the network infrastructure requirements. All related data for both logical and physical infrastructure requirements must be collected as much as possible. The following questions can be used to collect the data. 1. How many hosts will be in each site including workstations, servers, switches, routers, wireless access points, and VoIP. This will help in calculating and designing the IP address requirements. 2. Collect the information with the principal management if they need to host public resources either in Sydney or Jakarta sites. If so, where will all the public resources be located, inside the private network or in the DMZ (perimeter network)? This will help in designing the entry-point security. By hosting public resources, domain name must be designed in a secure manner such as separating the domain naming between internal and public usage. 3. Collect the information regarding the security requirements for internal network. Will particular sections or departments need security boundary? This will help in designing your computer network if the network segmentation within the local network is needed. And also helps in designing how the users are grouped and appropriate policies are developed to comply with the security requirements. 4. Collect the information with the principal management to develop service level agreements regarding the availability of the network resources. How critical the network resources will affect the business continuity if they ever fail to function. This will help you design the requirements of the redundant resources such as the need of clustering, load balancing and so on. 5. Collect the information regarding the location in each sites such as how good the power is, how long the distances between each building that will connect to the network, is it feasible to run the network cabling or wireless connection. If the wireless connection is needed, examine how the attenuation factors will affect the wireless performance. 6. Collect the information if the travelling users or tele-workers will be allowed to access the corporate network resources. This will help you design your VPN requirements and the security requirements regarding the authentication and the authorization for remote connection. 7. And still more diggings needed regarding the infrastructure requirements that is specific to the project. By having the brainstorming data regarding the infrastructure requirements you can make the budget regarding the hardware, software, and consultants requirements for the implementation of your computer network design. Disaster Management In your computer network design, the disaster recovery and business continuity planning should be in mind. The what if this fail question should base all the decisions of your design including selecting the location, hardware, software, models, the third party involves and so on. For example in building the server room, it’s a wise decision not to populate all the servers into a single main server room. Another alternate server in different building would be much better to avoid a single point of failure in case of the main server room is totally burned in fire disaster. The draft diagram of the computer network design should be evaluated precisely. Risk security assessment must be performed to help you design the appropriate control to reduce the possible threats to occur and if the threats ever occur, what actions must be taken to allow the business to run at least in the minimum operational level. In your computer network design should also consider the easiness in maintaining the system later by the administrators by providing a comprehensive documentation including the operational manuals and disaster recovery planning.
