For documents, enterprise data, design drawing and other important information store in computer, we usually set the boot password to avoid unrelated persons’ view or steal, enterprise will also launch related training to enhance employees’ awareness of data protection. However, under many irresistible impacts, this part of risks of information security needs more attention. Since the crisis of weak password has been gradually occurred, when facing more mature hacker techniques and increasing leak phenomenon, to use file encryption software to add a secure lock to enterprise equipment can make classified data secure in any cases.
Security experts said that for the majority of ordinary laptop users, the most common-used information security defense method may be setting boot password, and they will set longer and more complex password if they need stronger safety, while in this situation, the thieves can dissemble the hard drive and read its original data in another computer. This is virtually easy.
For users having some computer knowledge, he may adopt some advanced security measures, for example, setting a password to lock computer hard drive so that you will be required for correct password every time you start the computer; and even some one dissemble the hard drive, and it’s difficult to read the original data. But with the continuous development of hacker attacks, only depending on password can’t prevent experienced thieves erasing system configuration information to break into the system to obtain classified information.
There a very important point which is often overlooked by enterprises, that is, setting password can’t completely avoid initiative leak. As both setting boot password and hard drive locking password are defense means, no matter how strong or complex the passwords are, they are useless to initiative leakers. To effectively prevent various leak events including employees leak, data leak caused by laptop loss or stolen devices, one of the best methods is to encrypt the valuable files. Classifying the users’ permission and copying protect files on LAN can avoid employees copy the company files away; besides, employees should be forced to add protection to working files store in laptop and other devices to avoid data loss caused by device loss.
