4 PRODUCT OVERVIEW MDS can provide the Secure Cross Domain Guard Service which enables information to be shared in a safe manner. The service ensures that application level security is provided to prevent data loss and malware infection, within a security architecture, specifically developed to meet Government requirements for secure collaboration across security domains. The service is available to protect communications, web service communications, web browsing, file sharing and network management communications. The provided secure information sharing capability can be tailored to meet an organisation s specific business information sharing needs whilst addressing the threats faced in accordance with its security risk appetite.

The service supports the use of Government Security Classifications helping to protect users from inadvertently losing sensitive data. We provide optional utilities, for deployment on the service user s platforms, which facilitate automatic and manually controlled file sharing through the Guard service.

This facilitates a team approach to service provision and ensures that more than one engineer is aware and able to discuss and resolve your service requests. Service Request Categories The following table sets out the categories that will be assigned to each Service Request. Table SL1 Category Description 1 Total service failure of (operational) system or failure of a component of a critical process 2 Failure of one or more system functions making use of the system difficult (e.g. service still running and operational but not to full capacity) 3 Failure of a non-critical function having no significant effect on the system operation (e.g. failure of a sub-component such as a new version of an AV product) 4 Any incident having minimal impact on the system operation, requests for information or requests for enhancements. Service Levels The times indicated in table SL2 below are the target times for the Service Provider to respond to or provide a workaround for incidents as set forth in the Agreement. All periods of time commence from when the Service Provider first receives notification of a new incident. Table SL2 Response and Workaround Times Category Target Response Time Target Workaround Time 1 Less than 1 Working Hour Less than 1 Working Day 2 Less than 1 Working Hour Less than 3 Working Days 3 Less than 1 Working Hour Less than 10 Working Days 4 Less than 1 Working Hour As Appropriate

13 Escalation In the event that a Service Request is not provided within the relevant target time indicated in table SL3 above then the following escalation timings shall apply. For the purposes of this agreement, escalation shall mean the customer shall have the right to communicate with that person in relation to the provision of the Service Request. In the event that the identified individual is not available then the Service Provider shall use their reasonable endeavours to provide the customer with an alternate contact person. Table SL3 Category Service Delivery Manager Product Manager 1 Immediate Notification 1 Working Day 2 2 Working Days 5 Working Days 3 10 Working Days N/A 4 N/A N/A Security Flaws In the event that the Service Provider identifies security flaws in the software, the Service Provider shall categorise the security flaw in accordance with table SL4. Table SL4 Severity Description 1 Security vulnerability that allows Service Provider guard or administration system to be compromised (e.g. attacker gains control of the guard's host operating system). 2 Security vulnerability which means the Service Provider guard fails to block data that should be blocked according to the configured policy (e.g. data type configured to be blocked is allowed to pass). 3 Security vulnerability which means the guard fails to correctly identify the source or destination of data when applying policy (e.g. identity of originator of a signed message incorrectly identified resulting in loss of accountability). After categorising any emerging security flaw, the Service Provider shall follow the alerting and remediation process timings of table SL5. Alerting shall be to a customer nominated point of contact, using an agreed customer nominated communication means (e.g. secure address).
