Phishing Attempts Continue

by

Phishing

On October 9, 2009, more than 6000 UCI affiliates received an email message claiming that they were required to click on a link which would take them to a web site to update their email accounts. This message has been confirmed to be an example of “phishing,” a malicious attempt to have you divulge personal information in order to allow someone to gain access to your information or services.

The Office of Information Technology (OIT) would like to remind you that you will never be asked for, and you should never provide, your password or other personal information by email. If you ever question a request for information, please contact the OIT Help Desk at (949) 824-2222 or oit@uci.edu so we can help you check its validity.  If you suspect that you have received a phishing email, do not respond to it or click on the links. You may optionally report it to the Anti-Phishing Workgroup, but in any case delete it.

Spear phishing emails are a special type of phishing email targeted to a select group of users. These emails tend to be more specific than a regular phishing email, including information more detailed and familiar to the recipient. As with standard phishing emails, these messages often include a request for personal information and a notification of account suspension or closure for failing to reply.  At UCI, such a message will often simulate official notification from a real campus department such as OIT, and may make reference to your actual account or email address.

More information on phishing and how to protect yourself can be found online.  If you have not already done so, OIT strongly recommends you take the online “Information Security” tutorial available on TED.

ZotPortal: Online Resources for Students

by

ZotPortal

After an extensive campus-wide planning process, the student portal “ZotPortal” went live on April 27 of this year.  IAT-NACS worked with Student Affairs to design the high-reliability and high-performance system hardware, and provides ongoing network and system administration services, as well as housing elements of ZotPortal in separate data centers.

Through ZotPortal students can access academic and administrative information, connect to a Facebook account, subscribe to UCI campus news, student media and entertainment feeds, check UCI libraries catalogue and even search for people and campus web sites from one search box.

Students can arrange ZotPortal’s look and layout flexibly through a user-friendly drag-and-drop interface, subscribing to the particular information channels they want.

ZotPortal runs on hardware intended to provide maximal service continuity.  There are duplicate servers, connected through IAT’s DMRnet.  In the event one server becomes unavailable (say due to a power failure), the twin automatically assumes all portal activity.  Within each physical server are many CPUs, configured to provide a flexible group of virtual servers so that ZotPortal can support very large numbers of simultaneous requests.  Data is stored on a disk cluster configured with Sun’s ZFS (zettabyte file system) which provides both redundancy (data protection) and high performance parallel access.

Greenplanet: Cluster Computing for Physical Sciences

by

Greenplanet

Physical Sciences, with support from IAT-NACS, has assembled a high-performance computing cluster for climate modeling and other computational-intensive research.

Called “Greenplanet,” the cluster comprises nodes purchased by faculty in Earth Systems Sciences (ESS), Chemistry, and Physics, and it is expected that Math faculty will also participate.  At this time, Greenplanet includes almost 900 CPUs and is still growing.

IAT provides secure, climate-controlled space in the Academic Data Center,  system administration services as a team with Physical Sciences IT staff, and consultation on code parallelization and optimization.

According to Assistant Professor Keith Moore of ESS, Greenplanet is “a flexible cluster, suitable for massively parallel complex computations (such as climate simulations), and for smaller-scale use on a single node as a workstation.”

A typical node features 8 64-bit Intel CPUs.  Greenplanet features the Load Sharing Facility (LSF) for job management and the Lustre caching file system for extremely high-performance access to the large datasets typical of climate modeling.  Two message passing techniques are available for parallel code: OpenMP for communication between CPUs on a node, and MPI for communication between CPUs on different nodes.  Greenplanet also has the high-performance Infiniband interlink between nodes for high-speed communications.  There is extensive instrumentation available for tuning jobs to optimal execution speed and use of all available computational capacity in the cluster.

Software includes the Climate Systems Modeling package, parallel Matlab, and quantum chemistry packages such as Gaussian and Turbomole.

UCI Identity and Access Management Website

by

IDM

IAT-NACS provides a suite of identity management, authentication, and authorization services collectively referred to as Identity and Access Management services. A group of web pages has been developed describing UCI network identities (e.g., UCInetIDs), how they work, and how they will evolve.  There is a wealth of information for those interested in technical details.  Here are some highlights.

The campus directory provides contact information for campus affiliates, and allows you to control certain information pertaining to your network presence on campus, such as the server your UCI email should be sent to.

UCInetIDs are network identities issued to campus affiliates.  With your UCInetID and password, you can access a variety of online services, many through WebAuth.  IAT has recently extended UCInetID authentication, with appropriate limits, to applicants for admission, and third parties for whom some services will be provided.

UC Trust is a system for using each campus’s network authentication system (UCInetIDs at UCI) to access services, as appropriate, provided by other UC campuses as well as some companies whose services are restricted to UC affiliates.

Because UCInetIDs are so vital to conducting University business, IAT has developed plans for enhancing UCInetID security.  Also, as the number of users, past and present, grows, it will be necessary to upgrade UCInetIDs beyond their current 8-character limit.  You can read about this project online as well.
