Key Benefits of Server Message Block Signing

What is Server Message Block (SMB) signing and how can it help your organization?

Primarily used to connect Windows computers, SMB (also known as security signaling) is a commonly used client server communication protocol used for sharing access to files, printers, serial ports and other resources on a network. To help detect threats that target SMB data, specifically man in the middle attacks, organizations can configure SMB signing via group policy objects (GPO).

When SMB signing is configured, the origin and authenticity of network data traffic can be easily confirmed. This ensures the data's integrity and protects against potential attacks targeting any data transmitted over networks.

Why should your organization enable SMB Signing?

By implementing SMB signing, organizations can ensure the integrity of their data and detect potential attacks. Key benefits of enabling this measure include:

• Increased security: SMB signing helps detect unauthorized access to data and protect against potential attacks.
• Improved network performance: SMB signing improves the efficiency of data transmission over a network.
• Enhanced data protection: Organizations can detect data tampering and ensure data is not altered in transit.
• Compliance with industry standards: Many organizations are required to adhere to strict security standards and enabling SMB signing can help meet those requirements.

In summary, enabling SMB signing via GPO is a crucial step for organizations looking to improve their network security.
