iSCSI port

iSCSI Target (port 3260) facilitates the connection of data storage devices over IP networks. It allows for block-level data transfer, making it a key component in storage area networks (SANs). This service is essential for organizations that require efficient and scalable storage solutions.

What is iSCSI port

iSCSI Target, operating on port 3260, is a protocol that allows for the linking of data storage facilities over IP networks. It stands for Internet Small Computer Systems Interface and is used to facilitate block-level data transfers. This makes it a crucial technology for storage area networks (SANs), which are used to provide high-speed, low-latency storage solutions.

The iSCSI protocol was developed to extend the capabilities of the SCSI protocol over IP networks, allowing for the creation of SANs without the need for specialized hardware. This has made it a popular choice for organizations looking to implement scalable and cost-effective storage solutions. iSCSI Target enables servers to access storage devices as if they were locally attached, providing flexibility and efficiency in data management.

Historically, iSCSI has been instrumental in the evolution of networked storage solutions. It has enabled the consolidation of storage resources, improved data management, and facilitated disaster recovery and business continuity planning. Companies like Microsoft, VMware, and Dell have integrated iSCSI support into their products, further driving its adoption in enterprise environments.

iSCSI port runs on TCP and UDP port 3260 and is official IANA port.

Security risk

If port 3260 is open and the iSCSI Target service is running, it could expose sensitive storage resources to unauthorized access. This could lead to data breaches, data corruption, or loss of critical information. Proper security measures, such as authentication and encryption, should be implemented to mitigate these risks.

In our UFW tutorial you can follow instructions how you can configure UFW to close port 3260. Use StackChanges to monitor if the iSCSI port port is closed and stays closed. StackChanges will send an alert if port 3260 is open again.
