What is log management?

By log, I mean the “data history” of the system. Log management refers to collecting and managing data history.

Log management is the collection, monitoring, storage, and analysis of logs, which are records of operation details, usage status, and communication history on a personal computer.

Since you can record and manage not only the history of user operations and changes, but also the operational status of systems used for business and the occurrence of errors, you can quickly identify the cause when a problem occurs.

There are three log types:

Operation log

An operation log is a history of what kind of operations were performed on a computer or system.

Various operations such as browsing and editing files correspond to this, and it is possible to understand who performed what operation and when.

authentication log

Authentication logs are login histories that record who logged into a network or system and when.

In addition to computer and system logins, the login history to Internet sites is also recorded.

Since not only authenticated logs but also error logs remain, the possibility of unauthorized access can be discovered.

Event Log

Event logs record specific phenomena and actions that occur on the system in chronological order, but they basically record defects and errors.

Stable system operation can be achieved by collecting and managing event logs and clarifying the cause of errors.

Reasons why log management is necessary for telework

If you introduce log management for telework, you can accurately grasp the movements of employees during telework, reducing security risks such as information leaks.

Handling internal data outside the company during telework poses various risks such as information leaks and unauthorized copying of data.

If you manage employee logs during telework, you can check whether there are any unauthorized movements, erroneous file movements, or setting errors, even if you are away, so you can enhance your company’s security.

System selection points for log management in telework

On-premise or cloud version

There are two types of log management systems: on-premises and cloud.
When introducing log management for telework, the cloud version is recommended.

On-premise type

It is a format in which servers and network equipment are purchased or leased and installed and operated within the company.

Since it can be customized according to the internal environment, it is easy to link systems, but it is necessary to be careful because the fee is relatively high compared to the cloud type.

Cloud type

It is a format in which services can be used via the Internet.
The introduction cost is low, and it can be introduced as long as you have an internet environment and a computer.

With the cloud version, you can remotely manage personal computers as well as computers taken out of the office. Moreover, it can be easily installed without a server.
