Logsign Log Management

Logsign is an advanced SIEM security solution where the logs of the activities you wish to report on a specified network can be managed. It provides institutions with improved visuality and a better understanding of their networks.

What is the Security Information and Event Management (SIEM)?

It is the technology that is capable of performing sensitive and advanced data security log management within the scope of data security management, gathering the data collected in the data sources you designate to provide this management in a safe and manageable environment and making sense of this data for system administrators.

Mikrotik router can be accessed using winbox, webfig, and telnet client. But if the MikroTik router newly purchased or newly reset to factory defaults, you should know the default username and password of MikroTik router.

Collision is called the error that occurs at the same time both during packet sending and receiving. This is especially the case for devices that operate half-duplex, such as Hub and Repeater, that is, cannot send and receive packets from one port at the same time. Collision Domain is the area where there is a collision. In other words, it is a region where a collision can take place. Since Hubs and Repeaters send the packets they receive to all ports, there is one Collison Domain regardless of how many hubs and devices connected to the hub. Routers and switches have as many ports as there are Collision Domains. Because there is only one packet collision probability on each port. Briefly; While there is one collision domain at the hub, the switches and routers have as many collision domains as each port. Therefore, it is better to use switches and routers instead of hubs in professional networks

The first thing you need to do is to connect to your MikroTik router via winbox or an ssh connection.

After these operations, when you type the tool fetch command on the terminal and press the tab button twice, commands related to what you can do will appear.

For example, for downloading files to your MikroTik router, it will be enough to write tool fetch url = “link of the file you want to download”  and press enter. You will then see that file on your flash drive.

Learning Linux distribution information

The lsb_release command is used to get information about the operating system on Linux. Using this command alone does not mean anything, for this, it is necessary to use the relevant parameters after the command.

lsb_release [parametre]

Let’s see the lsb_release --help the command to see the available parameters:

If we want to see all the information, the lsb_release -a the command is used for this.

Learning kernel knowledge on Linux

It is learned by using the uname (Unix Name) the command to learn kernel information.
