The building's architecture may integrate other forms of security, including reflective glass, structural designs that block wireless signals, deceptive signage to camouflage the data center, and a lack of windows.
The building and property landscaping design are often tied to the physical security aspects of the data center.

The Common Internet File System (CIFS) is a dialect or an implementation of the SMBs protocol.
Most references will be to SMB, and that is the proper term by today's standards. One of the most common servers on the network are file servers. These devices are designed to store large numbers of files. Workstations access to these files from across the network. Application layer protocols manage file access. The two most common protocols are the Network File System (NFS) and Server Message Blocks (SMB).

Security information and event management (SIEM) software provides a centralized repository for logs, audit events, and security device alerts to detect and notify admins of suspicious activity.
For example, attackers can enable a backdoor on a compromised device that will provide them with undetected access for long periods of time; this problem is often solved by applying patches, but SIEM solutions may detect repeated abnormal login times to a server.

Both SAN and NAS systems are network-based storage solutions aimed at providing multiple users 24/7 access to data on-premises and remotely. Here are some differences between the two approaches.
Type of network: NAS is connected to devices using a LAN or Ethernet network, while a SAN runs on high-speed Fibre channel.
