Nowadays, with cybersecurity being top of mind for companies around the world, the protection of systems, network and data in cyberspace has become a critical issue, and there is no exception for public transportation operators. Therefore, MTR saw a need to carry out a system upgrade to automate daily IT security management and threat detection, with a special focus on the tracking of access to the corporate network.
MTR would like to automate the access control process further by building a stronger link between the privileged account management system and the production systems. In 2017, MTR started replacing its old security information and event management (SIEM) system with Splunk Enterprise, Splunk Enterprise Security (ES) and Splunk IT Service Intelligence (ITSI) monitoring and analytics solution and has derived benefits from the flexibility and additional values the solutions offer.
Operational visibility and real-time monitoring redefine threat prevention
Splunk Enterprise matches searches on all data sources in the MTR information system to analyze potential threats. Data from the Active Directory, privileged account management system and other sources are well integrated, and user login information is matched to approved user records, enabling automatic user tracking and identification. Splunk Enterprise has converted manual investigations into simple, proactive and automated searches, facilitating real-time security monitoring through internal risks and threats analyses.
Flexible graphical interface brings convenience and boosts efficiency
According to the MTR team, user analysis is as simple as a Google search with Splunk Enterprise. Unsuccessful login attempts and incorrect passwords are automatically tracked and reported. Unauthorized accesses can be traced layer by layer, from a network location to account ID, and then to the user identity. This prevents users from being able to gain unapproved elevated privileges.
The interactive graphical dashboard makes the network status clear at a glance. Users have anomaly detection and threat monitoring at their fingertips, resulting in unprecedentedly efficient IT operations.
“A turnkey analytics platform, Splunk offers us a rapid entry to actionable threat intelligence, giving us the visibility into potential risks in our production environment and a tool to monitor, investigate and report on them.”
Ted Suen, Head of Information Technology MTR Corporation Ltd.
Network access tracking done in minutes; resource utilization highly improved
Using correlation and analytics, Splunk Enterprise detects high-risk activity, access and events, providing actionable insights to the MTR team in minutes. After identifying a threat to the network, Splunk Enterprise will alert the team, and they can search through historical event data to determine the scope, intent and severity of the actions. Splunk software functionality frees up valuable time and resources for MTR’s IT team, enabling them to focus on value-added business activities.
Creating new possibilities for the future
The IT team has already extended the use of Splunk Enterprise to manage service performance and availability. The team is also applying Splunk Enterprise for the detection of external threats.
