4 Methods of Cloud Hosting Security

The development speed of cloud hosting is fast, but there are also many security risks. How should you solve the security risks? Here we introduce four methods to protect the security of cloud hosts:

1. Building a hardware security defense system Firewall, intrusion detection system, routing system, etc. are the components required for a complete security model. The firewall plays a role of security in the security system. It can largely guarantee illegal access from the network and data traffic attacks; the intrusion detection system plays the role of a monitor to monitor the entrance and exit of your server. Intelligently filter out visits with intrusive and offensive nature. At present, the hard defense system deploys a professional hardware firewall at the Internet exit, and sets filtering rules in the firewall to prevent illegal intrusion.

2. Adopt NTFS file system format The file system usually adopted is FAT or FAT32. NTFS is a disk format specially designed for network and disk quotas, file encryption and other management security features supported by Microsoft Windows NT kernel series operating systems. The NTFS file system cover can set access permissions for any disk partition individually. Put sensitive information and service information on different disk partitions. In this way, even if a hacker obtains access rights to the disk partition where your service file is located through certain methods, it still needs to find ways to break through the security settings of the system to further access sensitive information saved on other disks. As long as it is a Windows operating system server, the partitions are formatted in the NTFS format when installing the system.

3. The realization of the security of the cloud server's internal and external network isolation server system is closely related to the security strategy of the network system. Cloud hosts are divided into an internal network and an external network, and are separated by a firewall. The internal network and the external network cannot directly access each other. A demilitarized zone is set up between the internal network and the external network, and all access between the internal network and the external network is realized through the firewall. Based on the above principles, the network application system server within the group company should be located in the military zone to ensure its safety. The group company's business website, e-mail office and other servers are set up in the demilitarized zone to achieve intranet and extranet access.

4. Do a good system backup and data backup. Do a good job of server system backup. Once damaged, you can restore it in time. Do a good job of data backup, take local backup and off-site backup every day to ensure data security. For server operating system backup, after the operating system is installed, critical data backup and system backup are performed immediately: for data backup, a dedicated backup server is deployed in the internal network, and backup software is used for data backup.

Therefore, if you want to make your cloud host reach a safe state, you must configure server security in the system core of the cloud host, and deploy security policies.
