What is NetBIOS port used for?

NetBIOS is an older transport layer that allows Windows computers to talk to each other on the same network. Port 445: Later versions of SMB (after Windows 2000) began to use port 445 on top of a TCP stack. Using TCP allows SMB to work over the internet.

What is ArcSight smart connector?

Arcight SmartConnectors intelligently collect a large amount of heterogenous raw event data from security devices in an enterprise network, process the data into ArcSight security events, and transport data to destination devices.

What network application uses port 137 139?

The earlier version of SMB (SMB 1.0) was originally designed to operate on NetBIOS over TCP/IP (NBT), which uses port TCP 139 for session services, port TCP/UDP 137 for name services, and port UDP 138 for datagram services. (Read my previous comprehensive overview of the SMB protocol.

Is port 139 still needed for SMB?

SMB has always been a network file sharing protocol. As such, SMB requires network ports on a computer or server to enable communication to other systems. SMB uses either IP port 139 or 445.

Why is NetBIOS important?

NetBIOS stands for Network Basic Input Output System. It Allows computer communication over a LAN and allows them to share files and printers. NetBIOS names are used to identify network devices over TCP/IP (Windows).

What is ArcSight flex connector?

Flex connector is a custom agent where you can integrate devices which are not support by arcsight smartconnector. in this case you have to collect logs and create a custom connector using its different types, so that you can integrate required device.

What is an ArcSight connector?

ArcSight Connectors automate the process of collecting and managing logs from any device and in any format through normalization and categorization of logs into a unified format known as Common Event Format (CEF), which is now an industry standard for log format.

Is NetBIOS still used today?

NetBIOS (Network Basic Input/Output System) was created in the early 1980’s, but is surprisingly still alive and well on many networks today. Microsoft Windows still uses it for its name resolution function (often by default), when DNS is not available.

Is NetBIOS UDP or TCP?

The protocols in the NetBIOS over TCP/IP suite implements the NetBIOS services atop TCP and UDP, which is described in RFC 1001 and RFC 1002. NetBIOS over TCP/IP (also called NBT) seems to slowly supersede all the other NetBIOS variants.

What is connector in Siem?

The Falcon SIEM Connector provides users a turnkey, SIEM-consumable data stream. The Falcon SIEM Connector: Transforms Crowdstrike API data into a format that a SIEM can consume. Maintains the connection to the CrowdStrike Event Streaming API and your SIEM. Manages the data-stream pointer to prevent data loss.

What has replaced NetBIOS?

Today, DNS has replaced WINS, since Microsoft made changes to NetBIOS, allowing it to use the TCP/IP stack to perform its job (NetBIOS over TCP/IP) and most DNS servers are able to handle NetBIOS requests.

What ports do NetBIOS use?

NetBIOS over TCP traditionally uses the following ports:

• NBName: 137/UDP.
• NBName: 137/TCP.
• NBDatagram: 138/UDP.
• NBSession: 139/TCP.
