Win7 Offline (Offline Security?Trade data-driven portfolio management Win7 Offline User Guide) In today's Internet era, anyone wants to be able to connect to the Internet anytime and anywhere. However, sometimes for some reason, we need to work offline. Various cloud services, mobile devices, etc. have become the standard configuration of our daily work, but for some highly sensitive places such as military, finance and government, the Internet is not always a feasible or acceptable option. In this case, choosing offline work has become the only viable option. Under the Win7 operating system, offline work is not difficult. You can work and entertain freely without the network. This article will introduce how to better achieve offline security from the perspective of offline use of Win7.I. System Settings 1. Necessary software for installation: There are few ordinary computers that do not require software, which may be document browsing or virus software, etc. In Win7 offline work, installing the necessary software is the first step, which can not only meet your office needs, but also improve your work efficiency. Two. Disable the network card/unplug the network cable: The so-called offline work is to completely turn off the connection of the Internet, only in this way can the security of the work be ensured. Disabling the network card and unplugging the network cable are the two simplest and most effective ways to operate, which can prevent users from misoperation and causing the machine from being attacked. 3. Adjust the automatic update of the system: Since the Win7 operating system no longer provides security updates, it is necessary to adjust the automatic update settings of the system. In "Control Panel" - "Security Center" - "Update Settings", adjust "Update Program Download and Install" to "Do Not Check".To prevent misoperation or viruses from exploiting the vulnerabilities of Win7. II. Data backup is very important, and it is also the most critical link in offline security. In addition to saving your valuable data, it can also deal with emergencies. The following aspects should be considered when backing up: 1. Choose a good storage device: USB flash drive, hard disk, CD-ROM, tape, etc. are all common backup means. The larger the capacity of the storage device, the higher the security. Two. Backup strategy: establish rules for data backup, how to back up data, when to back up, etc. Incremental backup, full backup, differential backup and other methods can be adopted. Choose the appropriate backup strategy according to personal needs. 3. Data verification: After the backup, the data needs to be verified to ensure the validity of the backup. Malware or viruses can destroy your data, and it makes no sense to damage a backup system with invalid backups.III. Anti-virus and the system that drives Win7 have built-in anti-virus and firewall functions, which can be found in "Control Panel", "System and Security" and "Windows Security Center". But when offline, these functions will fail. Antiviruses and firewalls are preventive measures against viruses, Trojan horses and other malicious codes. Without these security measures, your computer and data will be threatened. It is recommended to install anti-virus software that the system can support and maintain an update policy consistent with mainstream anti-virus software. At the same time, considering that you need to run some programs, it is recommended to add a virtual machine to avoid driver incompatibility. Virtual machines not only avoid driver incompatibility, but also provide you with an independent running environment to make your data more secure.Summary Although the offline use of Win7 is relatively limited, in some places with high security requirements, offline work has become a necessary choice, and some common attacks and threats in the network will also affect your security. You need to take relevant security measures to ensure the security of data and computers. . The above content is only a preliminary reference, hoping to help people in the workplace better achieve offline security.
