Have you thought about a social engineering attack? What about users who use your network on a daily basis? Are you ready to face the attacks of these people?

Believe it or not, is the weakest link in your security plan for the people in your network. In most cases, users are not educated about how to identify and neutralize social engineering attacks. What happens to a user looking for a CD or DVD in the dining room and take their work and decide to open the files? This disc could be a spreadsheet or word processor, which is a malicious macro embedded in it. The next thing you know, your network is compromised.

This problem exists mainly in a box back with a password used by telephone helpdesk. There is nothing to a person intent on breaking into your network before you call the help desk to stop him, and asked an employee to reset a password. Most companies use a system to generate usernames, so it is not very difficult to find them.

Your organization should have to adopt strict policies that can, to a user’s identity prior to a reset password to check. A simple thing to do is to have users in the helpdesk in person. The other method works well if your offices are geographically distant, is a resource person at the office, a phone may appeal to reset it. In this way, the recognition of all those on the helpdesk works are the voices of these people and I know that he or she who they claim to be.

Why an attacker to make your office or call the help desk? A simpler approach is the path of least resistance. It is not necessary to spend hours trying to break into an electronic system, where the use of simple physical system. The next time you see someone walk through the door behind you, and do not recognize, stop and ask who they are and what they are there. If you have to do, and there is someone who should not be there, most of the time he goes out as quickly as possible. If the person is, then, it will produce in the best position, the name of the person he saw, too.

I know you say I’m crazy, right? Now think about Kevin Mitnick. It is one of the most decorated pirate of all time. The U.S. government thought it could blow the whistle signaling the phone and launch a nuclear attack. Most of his hacking was done by social engineering. If he has done through visits to physical offices or by a telephone call he made some of the biggest hacks to date. To learn more about him, Google his name or read the two books he wrote, know.

It is incomprehensible that the people reject and try these types of attacks. I think some network engineers are simply too proud to admit to their network they could be injured so easily. Or is it the fact that people do not feel they should be responsible for training their employees? Most companies do not give their department responsible for promoting physical security. It is usually a problem for the building manager or facilities management. However, if you can educate your employees the least, you may be able to breach a network of natural or prevent social engineering attacks.

That’s all he really is - a very important network. However, this article will explain just go on the Internet, as also explain the World Wide Web. Most people do not know the difference between the Internet and the Web, but in fact it is quite simple: the Internet is a computer network and the Internet is not a publishing system (sites).

Computer Networks

And what is a computer network? A computer network is two or more computers to send messages. In large networks, computers are complex arrangements in which some agents more than one computer connecting to other computers so that each computer can reach other computers on the network via paths through several intermediate computers are connected.

Computers are not the only things with networks - roads and rail networks are very similar to computer networks, transportation networks, only the people instead of information.
Trains on a network to work on one type of track - such agreement is necessary because otherwise the network can work effectively. Similarly, roads in order to adapt the vehicles that a kind of model - robust vehicles of a certain scale, corresponding to travel in a certain range of reasonable speed. Computers on a network of conventions, and we call”to keep records of these agreements.

There are many types of popular network today. More classic is by far the so-called “Ethernet” network computers as well as physical links in homes, schools and offices. However, WiFi is increasingly popular for connecting devices together so that the strings are not at all necessary.

Internet connection

When you connect to the Internet, you are familiar with networking technology, but things are usually a lot dirtier. There is a proper expression “Rome was not built in a day” because neither the Internet. The only reason that the Internet could spring has been so rapid and inexpensive for people, because another type of network already exists in the world - the telephone!

The pre-existence of the telephone networks to provide support for ordinary computers into the homes of ordinary people placed in the order has been placed on high-tech military and large research network will be connected during the years before developing . It only requires some technical expertise in the form of “modem”. Modems allow phone lines to a mini-network connection between a house and a particular company will be activated (an “ISP”), which is already connected to the Internet. It’s like a bridge connecting the road networks on an island and the mainland - the road to a project by a particular type of link between them.

Fast Internet connections that are on loan, “(A) DSL and cable” does not distinguish “real telephone connections online - there is still a candidate, the nature of the procedure goes behind the scenes. As Arthur C. Clarke said that “any sufficiently advanced technology is indistinguishable from magic.”

The Internet

The really amazing about the Internet is not technology. We actually had a large computer networks like the Internet before, and “Internet” for a long time before people knew the term normal. The amazing thing is that without massive computer network under construction or in any kind of organized way, it could seriously regulated. The only organization that is in fact a grip on its computer network at the heart of the Internet a government of the United States sponsored non-profit corporation called ICANN, but no one could control, “maintaining that the Internet their roles and activities is very limited.

The Internet is a will both be worked by the way and technologists running business is responsible for non managed to use the conventions of technologists to hook ordinary people and businesses. The Internet is not on the system’s operating system Microsoft Windows development - the Internet technology has existed for many older operating systems integrated the technology, but it could technology to computers running by simply entering the networking necessary to implement the Windows conventions. It was never intended to lead, but good conditions and the absence of constraints (eg control panels is often) significant unintended — as the telephone network before, or even the global spread of human population and society.

What I described to date is probably not the Internet, as you or most of it would be seen. It is unlikely that you will see the Internet as a democratic and unified network computer, and to some extent, it is not. The reason is that I just explained the basics of the system so far, and this basic work is below the level that you normally be informed. At the lowest level you would be aware that the Internet is actually more like a situation between a getter and a donor - it is something that you want from the Internet, allowing you to connect and get it. Even if you send an e-mail, you are still providing services of mail delivery.

As computer network includes the Internet from computers - but not on all computers on the Internet are the same. Some computers are there for services and some are there to consume these services. We demand the deployment of server computers and the computer uses “client”. Have on the theoretical level, the computer has the same status in the network server, but much better than the clients are connected, and are generally implemented by companies such a commercial transaction made. you do not pay to view a site, but someone will pay for the site server is located in the hotel - usually the owner of the site a “Web host pays” (a commercial company, the server).

Contact

I noticed how the Internet is a computer network: now I want to explain how two computers can be on different sides of the world may send messages.

Consider writing a letter and are required to send to someone. If you have only one name written on his forehead, he would never come, except perhaps that you lived in a small village. A name is quite rare. Therefore, as we all know, we use the addresses to contact someone, often with the name, number, street name, place names, the name of the county, and sometimes the name of the country. This allows sending messages to another type of network - the postal network. When you send a letter, normally it will be shared between the office of postal sorting offices, the postal distribution center near the origin, then the sort of up offices in more than biggest to them by a central sort the regions of origin and destination, then processed up Sort offices ever smaller, until the sorting office the next target - and then it comes.

In our situation after, there are two important factors at work - a form of remedy to this “real estate” on the target location, and a form of communication stretches “itself”, then “shrunk. Computers are better organized, but they are actually exactly the same effect.

Each computer on the Internet has an address ( “IP address”), and these “houses” on their site. The “homing in” are not necessarily geographically, but given the relationship of connection between networks smaller in the website. In the real world, it is a geographic neighbor, but on a computer network, the neighbor to be a direct network connection.

As the postal network, with its sorting centers, computer networks generally have little relationship to the other computer networks. A computer network will send the message to a larger network (a network to detect too), at least part of the address. This process of “extension,” will continue until the message from a network that will broadcast the treatment of “the objective, then appear the” squeeze-in “process.

An example IP address is ‘69 .60.115.116 ‘. They are only the number of groups in which group numbers are on the right side is always local. Each set of numbers is a number between 0 and 255. This is only an approximation, but one could imagine the meaning of this address:
A computer, 116
in a small neighborhood 115
in a large area of 60
Controlled by an ISP-69
(Internet)
The small area, the closer, could the ISP and the Internet, will focus on computer networks in their own name. Therefore, for a message to the same “Closer” would pass the message to one of these computers is through the closest and therefore lower in the right neighborhood, then click the appropriate computer.

Getting the message

Now that we are able to deliver messages, the worst is over. Everything we do is sort out our embassies in some way, it is logical to the other end must be fixed.

The letters we send in the real world always have things in common - they are written on paper and in a language which is understood as the sender and receiver. I intend to discuss these important conventions for networks to function, and this important concept holds true for our embassies.

All parts of the Internet to transmit messages in things called “packet writing”, and the layout and content of “packages” are made using the “Internet Protocol (IP). You do not need these conditions is, but you need to know that these simple messages are error prone and simplified.
You can think of “packages”, such as the Internet equivalent of a sentence - for a conversation, there would be many of them in two-way communication.

Where are the real message

Anyone who played the “Chinese Whispers” will confused ( “damaged”) messages, you may, if they are sent between many agents according to their origin to their destination. Computer networks are not so bad, but things go wrong, and it is necessary to be able to automatically detect and fix problems when they do.

Imagine you try to correct misspellings in a letter. Normally, it is easy to do because there are words much less than what is possible, combinations of words long letters. You can see if it is the combinations of letters can spell out words ( “error guessing”), and then easily see what is said to be the right word.
It does not work Reely.

Errors in messages on the Internet are to correct a very similar way. Messages that are sent are simply made more than they need, and say the extra space on the “sum of consumption,” the message as such - when the “abstract” the message is not found and an error message will be returned.
In fact, it is often possible, logically, with reasonable accuracy, what was wrong with a message without sending them to appreciate.

Detection and error correction can never be perfect, as the message and the “Summary” part could accidentally screwed up, so there is nothing wrong incorrectly. The theory is not an economy large enough “Summary” section, so that this unfortunate possibility is so unlikely that it can be safely ignored due.

Reliable communications on the Internet is via TCP. You may have heard the term “TCP / IP is the usual combination of” IP “and” TCP “and is used for almost all Internet communications. Intellectual property is of fundamental importance for the Internet, but TCP is not - there are indeed different “protocols” that are used, that I will not be able to cover.

Names, not numbers

When most people think of an address “internet” they think something like “www.ocportal.com ‘instead of ‘69 .60.115.116′. People refer to names more easily than figures, so that special machines, people have access) are usually assigned name ( “Domain Names”) with a system called DNS (the Domain Name System.

All Internet communications are still using IP addresses (Recall ‘69 .60.115.116 ‘is an IP address). The “domain names” are translated into IP addresses in the backstage before the start of primary communication.

In essence, the process of finding a domain name is fairly simple - it is a process of “homing in” on the left of the name, after a course of interrogation. This is better shown by example - “www.ocportal.com” would be viewed as follows:
Each computer on the Internet knows how the computer (the root of contact ‘,’ DNS server ‘) for things like “com”, “org”, “net” and “United Kingdom”. There are few computers and such we are contacted at random. The DNS server computer is asked if they know “www.ocportal.com and say they meet know which computer server is responsible for the” com “.
The “com server computer is asked, she knows” www.ocportal.com and answer that they know which server computer is responsible for “ocportal.com.
‘The’ ocportal.com server computer is asked if she knows “www.ocportal.com and answer that he knows the appropriate server computer that ‘69 .60.115.116 ‘.
Note that there is a difference between a server computer, the “head” for a domain name and domain names corresponding to the actual speed computer. For example, “ocportal.com” appropriate DNS server could not be the same server as “ocportal.com ‘themselves.

Given that certain domain names or parts of domain names are used very frequently, computers, remember to avoid the results of a “comprehensive” review for each name they should look. In fact, I greatly simplified the process in my example, because the look-up computer does not provide any real research on your own. If all computers on the Internet is full it looks congestion “is the root of the DNS server and DNS server for names such as” com. “Instead of looking at a computer each application on its own” server DNS local which is the recall after a partial result could be to assist or request (in whole or in part) from its own “local DNS server, and so on - until the worst case, the procedure must be completed.

Domain names are the person they want to register domain names with a representative ( “Registrar”) of the organization, for the rightmost part of the domain name assigned. When writing a company called VeriSign “(the” Network Solutions is a subsidiary) is responsible for things such as “com” and “network”. There are untold numbers of registrars operating system for VeriSign, and most domain buyers are probably not known to have the chain of responsibility - instead, they only areas that receive agent, and deal exclusively with the agent and its Web Host (because they are often the same company). Fields are not purchased but only leased and renewable for a period slightly longer than the lease period.
Effective dialogue
I was totally covered, as the essence of the messages are delivered via the Internet, but until now these messages are quite rude and unhelpful. Before meaningful communication can occur, we need yet another protocol layer (a reminder of IP and TCP) are already on our network physical layers.

There are many protocols that work on communications already established, including:
HTTP - Review Web page typically a Web browser
POP3 - for reading e-mail in the messaging software with its own PC, a user’s record
IMAP4 - for reading e-mail in the messaging software, with which he had deposited on the receiving server
SMTP - for sending e-mail software e-mail
FTP - for uploading and downloading files (even via a Web browser, even if a special FTP software is better)
ICMP - for “Ping”, among other things, (a ‘ping’ is the Internet equivalent of shouting a “you are there”)
MSN Messenger - it’s just one of many protocols that are not really the level, and joint meetings, but those designed by a single provider of software, created exclusively for the needs of its own software
I will not go into details of these protocols go, because it is not really relevant if you need to know really.

The information is transmitted via a protocol requests normally apply to something, or a response to something. For example, with HTTP, a client computer requests a Web page from a server via HTTP, then the Web server, in fact, reacts with the file in the HTTP server integrated.

Each of these protocols is to work with more or less than the so-called “ports”, and it is these “ports” that the computer knows to use the protocol to allow. For example, a Web server (specialized computer software, running on a computer server that uses data from Web pages is used), a port number “80″, and so if the server receives messages through this port they existing Web server software, who knows, by nature, it would be written to HTTP.
For a client computer, it is easier - he knows that a reply to a message he sent the same protocol, it will first be used. If the messages back and forth to the server computer and client computers in the control device of a so-called “power” (a clear conversation) between them. They are then able to log messages in the stream according to their original address and port number.

The World Wide Web

I explained how the Internet works, but not how the World Wide Web (the “Internet”). The Web is a publishing system that most people do not notice anything, is to distinguish it from the Internet.
The Internet uses IP addresses (often found on domain names) to identify resources, but the Internet has something more ambitious, because it would be absurd to any page on the Internet should be his own name ‘field’. The URLs of Web Applications “(Uniform Resource Locator), and I am sure you have printed on them as they now everywhere in the real world (though usually only briefly-) hand.

A typical URL looks like this:
lt; >://< Protocol address name_OR_ip field> /
For example:
http://www.ocportal.com/index.php
However, this is not really a full URL, because URLs can sometimes be much more complex. For example:
lt;> Journal >://< name: @ : port_num /
You can ignore the more complex example, because it is not really relevant for the purposes of this section.

HTTP is the nucleus for the Web. For this reason, the URLs usually begin with “http://”. Web browser is almost always also support FTP, so can take some of the URL “ftp://.

In general, the identifier “resource” is simply a file on the server computer. For example, would “mywebsite / index.html ‘file stored on the server the same way, in a special directory. On Windows, the” “symbol is used to write the directory names, but the Web has not been invented for Windows, use the conventions of operating systems older.

We now have three types of “Internet address” in order of increasing complexity:
IP addresses
Domain Names
URLs
If a URL has been in the web browser software by any player, then configure the Web browser would send a request to (typically using the HTTP protocol to remove) to the server computer via the URL identified. The computer server and then react, usually the Web browser would end up with a file. The Web browser would interpret the file to display, like any software running on a computer file that would include interpretation. For HTTP, the Web browser knows what to file, but because the HTTP protocol using what is called a “MIME type” to any type of server resources can send to interpret identified. If the Web server computer simply sends a file to disk and then the Web server computer uses the MIME type of the file extension (like. “html”) file.

A file “html” is the type of file that defines a Web page. It is written in simple language, and indeed the indications are mixed, showing that on a document with the document itself appears. If you’re curious, try to show the “source” function in your web browser when viewing a Web page, and you will be a mixture of parts of the text of the normal and short text between ‘ and symbols “. The first is the content of the document and it is the guidance display.
In new versions of HTML, there is a gap between “design” of a document and display “a structure - in this case a special technology called” CSS “is added to the mixture.

I, as a conventional Web pages are presented only files on the hard drive of a computer server. Increasingly, things are a little less direct. If you go to something like eBay, your Web mail or a website ocPortal-fed, you’re not just reading files. You are currently interacting with the software, and pages as you pass through the new software each time a request is processed. These systems should be replaced as “web applications” and increasingly the need to install software on your own computer is known (because there is so much easier to use a Web browser to a Web application) on a access to the server.

Why get cable TV when you get competitive prices for satellite instead? One reason is to go with cable TV, so keep in touch with your neighborhood. While the local TV channels by satellite are available, it may add a surcharge for these channels. With cable, these channels are usually discarded at no additional cost, but you should ask to ensure that such is the case with a company you choose is to do business. In addition, your business cable television and probably also some channels that are only on cable. The update includes May and close proximity to new schools, city and programming of the county administration, and other news and information for your area.

It may not seem a big problem for local television stations. Because the programming for the channels that you normally take everything what you want. Or channels have almost everything. What They Don, do you have AOT news and community events, unless you live in a big city. If you know what the weather is like tomorrow, Don, AOT want to turn on the TV and just looking for someone to predict the three countries. They want to know what time it is in your region of your state. TV cable, you can help. Local channels can also keep you informed of events and school closures in bad weather and much more.

Many people enjoy satellite TV because of parental control options. Some aren, AOT aware that the same options for users of cable TV are available. This way, you can enjoy all the channels you want, but you limit your child AOS account. You get to decide which channels are suitable for display, not that anyone in the entertainment industry. This way you can ensure your TV programs simultaneously your values.

The amazing thing is that you know may even find firewalls available free online if you know where to look. I highly recommend paying for a firewall, but if you have little knowledge about the inner workings of your computer. If you, your family secrets, you can also a very good program to invest, with constant updates to ensure that.

A firewall computer is not only a nice thing to have on your computer, it is an important line of defense for you and your family. Please keep that in choosing the best firewall for you. Remember, you want a service that updates and keep up with technology that would harm your computer or steal your personal information.

Watched anonymous proxies serve as a wall between the customer and the service is. These servers can be used to circumvent the restrictions and access to these services may be blocked by the country or any other organization to provide Internet access, while others may be assured that privacy that may be used .

Risks behind anonymous proxy
Because, anonymous proxies, especially those on Web pages designed to provide all information to the proxy servers are not encrypted. Therefore, it is possible that sensitive information like usernames and passwords from malicious proxy server may be recorded. Even through proxy chaining, some clients may suffer as a Web page with an incorrect security measures to ensure that all proxies within these chains to monitor client activity. So, only trusted anonymous proxies with a clear privacy policy should be used for security reasons.

As this file important documents

When organized in a document file it vertically and in alphabetical order and put a full name at the head of Manila file folders. Categorize generate the types of files: one for household information, another tele-classes and conferences, one for customer management, and another for the promotion online and off.

In a word computer folders to organize information alphabetically. “My Documents” contains these and many more, but with this technique, you’ll always know where the most important information because it is organized and categorized into folders for examples: submit articles, contact influential, ClickBank, promotional campaigns for the month and of course records for books in Word and PDF. These files are the lifeblood of any business.

Make sure you keep only information that supports your best life. With only 20% that you produce, you can in less than two minutes to find!
