Most people wonât have File and Printer sharing enabled on their home computers, but they may still have other vulnerabilities. Windows XP comes with web server and remote administration disabled by default.
And then there are those port scanner programs hackers use, scanning the Internet for vulnerable PCs. Some sites, such as Shields Up, make great play of this, especially having the key Netbios ports 135-139 open, but fail to clearly explain exactly what hackers can do with them.
The fact is that even if a hacker did interrogate these ports, all they would retrieve is your computer and workgroup name, along with its description â no big deal for a stand alone home system. Still, you may want to close these ports anyway.
There are also personal firewall programs which can detect and stop attempted probes into your system. Windows XP comes with a firewall by default, but this is a one way firewall. A more secure, and free firewall is zone alarm. If you are a novice its best to stick with the default Windows firewall, but if youâre a more advanced user and familiar with most technical details on your computer then you may consider it best to install a more secure firewall like Zone Alarm, or something else.
Firewalls can detect and stop probes into your system. If your system is properly secured, any probes will have no effect at all, so all the firewall is doing is telling you about them. Itâs better to spend time checking your computerâs security rather than spend money on a firewall.
The Real Danger
Anyone who knows about Trojans will realize that itâs not entirely safe out there. A Trojan differs from a virus in that it appears to be a useful program, which you happily install and use. Unfortunately for you, the apparent function masks something much nastier. The real payload can be anything the author likes, but the particular type of program weâre interested in is known as a âbackdoor Trojanâ.
One of the worst is known as SubSeven. Once youâve installed the active part (the âserverâ, which can be bound to any other EXE file so youâll never know whatâs going on), it attempts to broadcast to its author via IRC every time you go online. They can then use the âclientâ part of the program to literary take over your computer. Of course, itâs unlikely to do anything dramatic immediately, but the potential features are very dangerous indeed.
It can log key presses, for example, even while offline, then transmit them to the author, so anything you type (passwords, credit card numbers) is at risk. SubSeven also has a comprehensive file manager, enabling the remote client program to browse your system, accessing or running any file on your computer. And if you really want to be scared, email us for the complete list of the 113 functions it is able to perform.
Donât be Complacent
Itâs easy, and certainly more comforting, to imagine that you wonât be affected by a Trojan like SubSeven. After all, setting up and using something like that must be a very difficult process, right?
Wrong, Unfortunately â take a look at SubSeven. Anyone can download the program, and even get help about how to use it, just like any other software package. Itâs easy and itâs free; kids could set it up (and some probably do).
But surely your anti virus program will be able to detect it? Well, maybe, but the author of SubSeven has a way to bypass that. New versions are released frequently, with more powerful features than the last, and once the server part is installed on your system it can be updated remotely. This means that by the time your anti virus software knows how to pick up one version, the copy on your system might be quite different.
And whatâs more. SubSeven is only one program with these capabilities. There are hundreds, maybe thousands of programs exactly like SubSeven equally capable of permitting others to access files on your computer. Trojans like this are the biggest Internet threat to the security of your system, so what can you do to protect yourself from them?
Get the Right Advice
One thing you should not do is simply download and use the first Trojan detection program you can lay your cursor on. Beware also legitimate software that makes excessive promises. Promises that it will detect and remove all known and unknown Trojans. If itâs that good, why is the program already at version seven?
All detection software requires frequent updates just to keep up, and no one can guarantee to defeat all future threats.

Education opens the doors to a completely new world of jobs and dream careers. Education is the best gift one can give oneself. There are plenty of educational opportunities available for those who seek to further their economic goals in life. A good college education is the best option for this. Although experience is essential, a lifetime of experience will not help to achieve the same level of education that an undergraduate college course will impart.
A college degree entails a huge investment of time and money, but in the long run it increases the individual’s earning potential and improves the overall quality of life.
Every level of college degree increases the earning potential. For instance, a yearlong degree course in any technical field will provide higher advancement in the career as compared to a high school diploma and the earning potential will increase manifold incase the individual upgrades from the associate degree program to a bachelor’s degree.
By the same logic, graduate students who opt to study for the master’s degree have a greater earning potential as compared to the majority of students who start working after attaining the bachelor’s degree.
A college education is very costly and the reason why most people avoid going for higher studies. Most often due to pressing responsibilities, people have to quit studying and start working in order to earn a livelihood. Due to improvements in the information technology, it is now becoming easier to obtain a degree for those who have sacrificed their dreams of further education. It is now possible to take classes online or join Saturday classes or night classes in order to get the college degree. This can now be done simultaneously while pursuing your career, in order to achieve your goals for a bright future.
Lack of a college degree can seriously hinder your chances of a good career opportunity. The lack of formal education will limit your possibilities much more than the lack of experience in the particular field. Today most businesses seek to hire employees with college degrees rather than those with experience, a trend that is continuing to grow. In order to remain competitive in the work field, you will need to equip yourself with the proper type of education and training required to perform well at the job. If you are already employed, you can check with your company if any incentives are provided to employees who are continuing with their education. Sometimes, some companies are willing to reimburse the education expenses if the degree you are studying for, is directly beneficial to your current nature of work.
A college degree and education in general, is never a waste. Even though your degree may not be of use in the job that you are applying for, the fact that you have a degree will give you an edge over the other job applicants. Therefore, it is vital to have a college degree and formal education if you wish to gain a foothold in today’s competitive job market and business environment.
