In today’s world, computer has been very important in our daily life. Almost everything surrounding us is computerized, and everyone around us is equipped with knowledge of information technology. Computer becomes necessarily important especially in working places. Works done by computer includes accounting, auditing, storing information of company, and sending information to related users. Due to the improvement in technology, computer crime becomes one of the ways for hackers to obtain unauthorized data without prior notice of the owner. Therefore, safeguarding our data in computer is the only way to prevent lost of data.
There are several ways to safeguard our data from unauthorized access by intruders. The most common ways that intruders use to steal data is to steal information in the sending process when we are trying to transfer our data to intended user. Therefore, encryption becomes one of the best ways to safeguard our data during the transferring process. When we send information through email, we can encrypt our email before sending to recipient, and the recipient will use decrypt software to read the information that we are trying to inform them. Encrypted email is done by transforming words to unreadable icons or shapes before sending, while decrypt software can help to scramble the icons back to the original words. By doing this, even the email is interrupt by intruders during the sending process, they will not be able to read the information.
Next, we can set up user names and passwords in our computers and office. These user names and passwords must not be accessible by anyone else, including close friends or colleagues. This is to prevent our data being unauthorized access by others when we are away from our keyboard. Besides that, we should set up different usernames and passwords in order to further protect our sensitive information. However, we must ensure that we must not forget our own usernames and passwords so that complications can be reduced to minimum. Changes in usernames and passwords after some period can also help to ensure that unauthorized users will not be able to access our information.
Besides that, we can also deploy firewall in our computer. The main purpose of firewall is to block unauthorized access while allowing authorized entry. It is a part of a computer system that can help to permit, deny, encrypt or decrypt access based on certain criteria. Firewall can help to block intruders from access into our computer through network, and they will require obtaining permission from us before accessing our personal and financial data.
Every computer users are fear of viruses. This is because viruses can be created by any virus writer to spread through network, computers or removable devices. Therefore, updated antivirus software shall be installed in every computer before the operating system is infected by any viruses. There is some free antivirus software available in the market, such as avast! antivirus and AVG scanner. Computer users also can purchase original antivirus software from retailers to obtain advanced protection against viruses, worms, and Trojans on disk, CDs, in email, and during browsing.
Last but not least, users of computer shall backup their data in different devices and locations especially important data. Whenever there is a lost of data, they will still have a backup copy to trace back the information. Users also advised not to store all data in one particular place so that they can minimize the effect of lost of data. Storing data in different devices also helps to diversify the risk of lost of data.
