What is Advanced Threat Protection?Advanced threat protection (ATP) is a proactive security solution that defends against attacks by malware. One of its important goals is to prevent any malware from reaching and running in the protected devices. Usually, ATP deploys on cloud where files from  the internet are scanned and run in a remote dummy machine (sandbox) before allowing the files to be sent to the devices.

In the previous two articles (Ref: September 2015 and March 2016), we have introduced Windows 10 and its deployment plan on both Student LAN and Staff LAN. Subsequently, the Computing Services Centre (CSC) deployed Windows 10 for teaching and learning in the CSC teaching studios, lecture theatres and classrooms in August 2016. In the meantime, Windows 10 was also deployed in several departments as a pilot. Since the pilot run of Windows 10 has been successful, campus-wide support for Windows 10 on Staff LAN is now ready.

/* The following article is extracted from the "Information Security Newsletter" published by the JUCC IS Task Force.Network forensics is the technique in capturing, storing, and analysing network logs in incident events. It also comes in other names, such as specific packet mining, packet forensics, or digital forensics. Regardless of names, the idea behind is the same: to record every packet of network traffic (emails, database queries, Web browsing – all kinds of traffic traversing an organization’s network) into a single searchable repository to facilitate the detailed network examination. This paper presents challenges raised and technics to perform network forensics.

Location Services.Location services system has been around for quite a number of years, such as Global Positioning System (GPS) and GSM. Unfortunately, they do not work well indoors because of signal characteristics and coverage. With the proliferation of Wi-Fi, Bluetooth and the mobile devices, the indoor wayfinding system becomes technically feasible. The Computing Services Centre (CSC) and Library have recently conducted a Proof-of-Concept (PoC) trial to evaluate the technical feasibility.

CityU values the diversity of its students and is committed to providing a learning environment that is conducive to the success of all its students, including those with Special Educational Needs (SEN), in their academic pursues and personal developments. In supporting the IT needs for SEN, the Computing Services Centre (CSC) has, for many years, equipped and improved special facilities and more are added recently.

/* The following article is extracted from the "Information Security Newsletter" published by the JUCC IS Task Force.Distributed Denial of Service attack is one of the most menacing security threats on the Internet. In order to put down these attacks, the real source of the attack should be identified. IP traceback is the function to trace the IP packets within the Internet traffic.

PC Hardware.Further to the PC upgrade last year, the remaining half of the CSC Teaching Studio Areas, around 500 PCs, have been upgraded to newer hardware this summer. These PCs are also configured as diskless start-ups with Citrix Provisioning Services (PVS). The computers boot up from the network and read the virtual hard disk content from PVS servers on the fly. As the write operations are cached on the device RAM temporarily, users are advised to save their working files on removable storage devices, such as USB flash drive and USB HDD/SSD. Besides the USB 3.0 ports, there is also an USB 3.1 Type-C port on each new PC which can support faster USB devices at a speed up to 10 Gbps. In order to provide a larger write-cache and more working memory for Windows 10 (64-bit), both the old and new PCs have been upgraded to 64GB of RAM.

Being a young university with vitality, City University of Hong Kong has always been ambitious and courageous to explore cutting-edge technologies which may benefit teaching and learning on campus. In order to search for and promote suitable technologies in classroom, the Smart Classroom Working Group, which is composed of members from various academic departments and central offices, responds to the calls for more effective solutions for teaching and learning.

CityU Scholars is set to promote the achievements of faculty members, facilitate reporting information to the government, enhance the efficiency of internal reporting, and eliminate duplication, according to Professor Lu Jian,Vice-President (Research and Technology) (VPRT) and Dean of Graduate Studies at City University of Hong Kong (CityU).

Why to Migrate?With the evolution of best practices and IT Service Management (ITSM), the Computing Services Centre (CSC) has been planning for years to upgrade its IT Service Automation platform. The old Help Desk System has been used since 2001. The plan is to migrate from an on-premises implementation to a Cloud based ITIL (Information
