Advantages of internal and external network isolation
Data security: Intranet and internal network isolation can help enterprises isolate core data, achieve security protection of core assets, and prevent employees from easily leaking confidential company documents. At the same time, it can also effectively shield the risk of external cyber attacks.
Protect core data: Even between internal colleagues and different departments, files cannot be transferred to each other at will, which further protects the security of core data.
Disadvantages of internal and external network isolation
Inconvenient to use: Due to network isolation, some cases where you need to transfer files to and from each other can become cumbersome. For example, although the U disk ferries files can realize file transfer, it lacks logs and approvals, which may waste labor and may also carry viruses. Some traditional transmission methods, such as FTP, can realize file transfer, but the security is poor, the transmission is not stable enough, and there are problems such as unreasonable interruption, inconsistent content of transferred files, and loss of transferred files.
High implementation costs: Although the data security benefits of network isolation are high, they often bring some minor problems in use. For example, the dual-NIC host can centrally control data, but it is difficult to ensure security, there is no approval and audit function, and the hardware implementation cost is relatively high. Gates are highly secure and inexpensive to implement, but only file exchange records cannot be traced back to specific users.
In order to protect their data security and ensure that data is not leaked, many enterprises will choose to isolate internal and external networks. The specific isolation methods vary from enterprise to enterprise, and you can choose physical isolation, DMZ isolation, dual NIC host isolation, firewall isolation, VLAN isolation, optical shutter network gate isolation, virtual desktop isolation, etc. However, these isolation methods will bring some inconveniences to use to a greater or lesser extent. Therefore, it is particularly important to find a suitable data ferry product.
