Network Services & Security

CCB uses proven approaches and existing network monitoring tools to monitor network uptime, as well as traffic and performance bottlenecks.

Network

The LONI intranet consists of a switched 10baseT, 100baseT and 1000baseGigE ethernet as well as an IEEE 802.11a/b/g-compliant wireless network. The laboratory is connected to the vBNS backbone of Internet2 via redundant fiber optic 1000BaseGigE lines terminated on two independent routers. While UCLA Campus Telecommunications Services (CTS) is responsible for the network and provides fault tolerance, network monitoring and load balancing, the redundant uplinks ensure that the facility’s network connectivity will be maintained in the case of a single router failure. The facility has a firewall providing network security. Furthermore, LONI has implemented a virtual private network to facilitate access to internal resources by authorized users. A virtual private network connection establishes an encrypted tunnel between client and server, ensuring that communications over the internet are secure.

Security & Performance

The CC provides mechanisms for archiving, retrieving and sharing data in a manner compliant with Health Insurance Portability and Accountability Act (HIPAA) regulations. The data archival process ensures that all incoming data are de-identified prior to transmission to the archive, that all data are securely transmitted using encryption, and that no unauthorized person may access the archived data. The user interface enforces security constraints on querying, organizing and viewing data according to user authorization levels. Host and network-based security policies further protect the data archives housed in LONI.

Communication

Our facility has been selected by UCLA Campus Telecommunications Services (CTS) as a university pilot site for Voice over IP (VoIP) telephony. VoIP defines a way to carry voice calls over an IP.
