Computer Security - What Exactly Is It?
by: Ciontescu Molie
Although the term 'computer security' is used a lot, the content of a computer is actually vulnerable to only a few risks unless the computer is connected to others on a network. As the use of computer networks (especially the Internet) has increased dramatically during the past few years, the term computer security is now used to describe issues referring to the networked use of computers and their resources.

The major technical areas of computer security are confidentiality, integrity and authentication/availability.
- Confidentiality, also known as secrecy or privacy, means that the information you own cannot be accessed by unauthorized parties. Breaches of confidentiality range from the embarrassing to the disastrous.
- Integrity means that your information is protected against unauthorized changes that are undetectable to authorized users. The integrity of databases and other resources are usually compromised through hacking.
- Authentication means that an user is who he claims to be.
- Availability means that the resources are accessible by authorized parties. Examples of availability attacks are the 'denial of service' attacks.

Other important things that the computer security professionals are concerned about are access control and nonrepudiation. Access control refer not only to the fact that users can only access the resources and services they are entitled to, but also to the fact that they can't be denied to access the resources they legitimately expect. Nonrepudiation means that a person who sends a message cannot deny he sent it and vice versa.

In addition to these technical aspects, the concept of computer security is very large. Computer security's roots are drawn from disciplines like ethics and risk analysis and the major topics that are concerning it are computer crime (tries to prevent, detect and remedy attacks) and identity/anonymity in cyberspace.

Although confidentiality, integrity and authenticity are the most important things when it comes to computer security in general, for everyday internet users, privacy is the most important one, because many people think that they have nothing to hide or the information they give doesn't seem sensitive when they register with an internet service/site.

But remember that, on the internet, information is very easily shared among companies and small pieces of related information from different sources can be linked together to form something alot more complex about a person. Because of this, nowadays, the ability to maintain control over what information is collected about them, who may use it and how it can be used is extremely important.

How SMS Works
 by: Jim Sherman

SMS, or Short Message Service, is the technology behind what we often refer to as ‘text messages’ or ‘SMSes’, as well as what allows for news alerts on cellular phones. In recent years SMS has ballooned to over a 50 billion dollar industry and is quickly taking the communications world by storm.

Short Message Service actually refers to a framework that uniquely allows computers, or in this case phones, to communicate with each other without the need of a central hub. With SMS, phones can find each other, send short packets of information back and forth, and do it all without any central computer to guide them. But because the system does not rely upon fixed lines like a land based telephone system does, the amount of information that can be sent at one time is limited in size. This depends on the language spoken, but for English letters this typically means around 150 characters (Chinese and Japanese letters are limited to 70).

Quite recently, however, new developments in the technology have allowed for even longer messages to be sent. Long or Concatenated SMS is a development that allows multiple messages to be combined to form a single message. In effect, what happens is that your phone actually sends out a few smaller messages and then the receiving phone simply compiles those messages so that for users on both ends, it appears as though the message were cohesive. While there are some limitations, the brilliance behind SMS is that because there is no need for central hubs, and thus the system can be expanded indefinitely without any concerns of it slowing down or becoming more expensive.

The most common form of SMS is ‘texting’. This usually takes place with a cellular phone in which individuals use the letters behind the number pad on their phone to spell out words and phrases and then send them out. Because many companies charge by the word, individuals have come up with a sort of ‘texting slang’ to cut down on the amount of words required to convey a particular message. For example, ‘gr8’ and ‘BTW’ mean ‘great’ and ‘by the way’. In addition, other words have just been shortened, such as ‘lata’ to mean ‘later’. Most users simply pick up the lingo through frequent use, and although some slang is widely understood and used, other shortcuts are developed within circles of friends and family.

The major advantage of SMS is its price. The price is typically $0.05 per message, a significant cut below that of traditional telephony and cell phone per-minute charges. The savings of SMS has its roots in the nature of the technology. Short Message Service, like SIP, is modeled on a peer to peer model and not a cog and wheel like traditional communication systems. This means that instead of having to route a message through a central hub, your text goes straight from you to its destination. This has radically cut down on the cost of SMS implementation and led to its overwhelming popularity throughout the world.

Short Message Service (SMS) has radically changed the face of the communications industry. While the practice has become quite common throughout the world, it has only recently become popular here in the United Stats, a growth partly predicated upon, surprisingly enough, its featured role in the show American Idol. The fact that ‘texting’ is quickly gaining both in popularity and recognition in the United States is not surprising however, due to its ability to offer users a cheap, quick, and often fun way to communicate with friends and family.
