Vulnerability management type
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Vulnerability management approach
All Horizon services are continually monitored by the HTK Operations Team using industry standard tools and methods to identify potential threats. At the first sign off a threat the team make an assessment of the risk and instigate appropriate action. The action taken may require support from other HTK teams and any major threat will be immediately reported to senior management to ensure appropriate resources are allocated to address the threat. Depending on the requirements patches can be deployed in a matter of hours.
Protective monitoring type
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Protective monitoring approach
As previously described all services are actively monitored 24 x 7 to identify any potential compromises. The HTK Operations team will ensure all the relevant people are informed of the potential compromise and create an action plan to deal with the root cause. Depending on the level and complexity of the incident a response can be implemented within minutes or at most a few hours.
Incident management type
Conforms to a recognised standard, for example, CSA CCM v3.0 or ISO/IEC 27035:2011 or SSAE-16 / ISAE 3402
Incident management approach
The HTK Operations team have a pre-defined set of processes listing the actions to be taken to resolve common events. These processes are regularly reviewed and updated. Users of the Horizon system can report incidents through the HTK Support Desk by email or telephone. The user will receive regular updates on the actions taken to resolve the incident. HTK operates an internal "always on" shared messaging system used to report incidents, request support and track progress of actions taken to resolve the incident.
