Keeping Information within Server Walls

By

Information gathered by a company will always be important and they should not be shared, disclosed or disregarded in any way, since they are the life stream that a company or organization thrives on. Normally, information would be stored in databases and only authorized personnel would have access to them for reference and study on current and probable studies for overall organizational performance.

Rumor Mongers

The security of information is usually left to the jurisdiction of the database administrator and information technology section of companies. While some would consider this department as all computers and no importance, the position they actually hold is important and should be given notice.

Many would consider IT people as expendable, but the truth of the matter is, they bring the secret and the backbone of a company’s information gathering background, and should breaches be experienced, they would be the first ones to know how to do it.

The Potential Threats of Foregoing Cyber Security

By

While most of the world relies heavily today on computers and the Internet, safeguarding data and intrusion from malicious hackers and technology advanced individuals should be the main cause for concern.

Cyber Security

It is no secret that most systems that do not have the proper security programs face the risk of potential loss of information or being a cause for downtime for servers that need to be operational 24/7. Without the security perimeter fences installed, a server or workstation is prey to a lot of attacks stemming from hackers, worms and Trojans that are spread all over the Internet today.

The risk is indeed high considering that a lot of personal and business related programs and files are the bloodstream of most operational works today. Without the proper cyber guards to act as assigned protectors to key data, internal operations and key components in systems will surely be facing threats that may not immediately be recovered by back-up systems alone.

Formatting May Be the Answer but Is not the Only Answer

By

People who own computers who have given up hope for remedying the problems that their workstation has solicited, either from viruses, Trojans or spyware will normally resort to formatting and re-installation of all programs to make things easier for them. This is usually the case for people who would not bother finding ways on solving such issues, the less technical savvy people who want the best and fastest solution to such issues.

Formatting Computers

People, often referred to as geeks would go at anything to be able to find alternative solutions without having to resort to the dreaded formatting decision since it will entail a lot of issues such as data loss and re-programming as well. While it is true that it is like doing a general cleaning for the entire workstation, historical files and programs will surely be missing one by one. But it is also like starting from scratch and locating the files and programs that a person has been used to having around.

Knowing When to Use System Restore in Windows XP

By

For the people who have not yet shifted to the new installment of the Windows operating systems known as Vista, a lot of people are probably aware of the System Restore feature that Windows XP has. While such a feature is indeed helpful, especially once systems start going haywire, it also has its side effects especially when viruses and Trojans start infecting a PC or workstation.

Restoration of System Resources

For one, cleaning up is done only on the machine at its current state. But with system restore, it backs up files unknowingly and in the process, the viruses and infections as well. The best thing to do during infected states is to temporarily turn it off, clean and disinfect the computer first and then turn it on again.

This is to ensure that the files, including the files backed up are properly cleaned in the process. The new data backup will also overwrite the old ones so that a clean and well-oiled system is being used.

Fluctuations can Crash System Hardware and Software

By

The sudden fluctuation of electricity can harm any computer if a person is not careful. The flow of current in the computer is sure to become a problem, especially if the assembled hardware are abused by continuous disruptions which may eventually lead to system crashes from unstable operating systems or hardware. This usually occurs while a computer is on and is not protected by the usual automated voltage regulators and uninterruptible power supplies suggested today for them.

Candles during Brownouts

While most entities are equipped with generators to back-up power failures, the important thing is to allow a computer to be shut down properly beforehand. Generators are activated after 5 to 10 minutes which only produce the current from that point. Computers automatically shut down once power is cut. This is why backup batteries are created to allow proper time to back-up and shut it down properly to ensure proper system and database integrity of computers and servers today.

The Importance of Knowing Filename Extensions Prior to Opening Them

By

Computer interface with various developed programs and most would have an assigned file name extension tagged to it. There are the usual files that would have a doc, xls, ppt, jpg and bmp file extensions. There are also the compressed files such as zip and amr. The compressed files offer some potential risk since they are usually zipped to group files into one manageable file. Program scripts and installation software are the common contents of these zipped folders to save on space and to make it easier for distribution and transfer.

Filename Extension Genius

It is best to proceed with caution before totally unzipping the contents to any directory of your computer. It is the executable files such as the setup.exe that may garner much doubt. Once executable files are double clicked, it will immediate process and try to install itself on the machine. Once finished, there is no telling what effects it may do or create, thus the need for people to think twice before clicking on the files.
