Information security policies and processes
The GRC IT Security Policy is designed around the core principles of Confidentiality, Integrity and Availability, with the primary objective of asset protection, prevention of unauthorized access and ensuring the availability of systems and information for GRC and our customers. Within the GRC domain these principles are achieved via a range of mediums, including centrally monitored anti-virus and malware protection, network level hardware and client level software firewalls and Active Directory controlled user accounts, with senior management approved role-specific permissions. Due to our requirement to work with evolving technologies, we make clear distinction between the GRC domain and Engineering tasks, which can only be performed on specialist off-domain clients, further minimizing risks to our network. Familiarization of this IT Security Policy is part of all employee’s induction and its acceptance is mandatory

Operational security

Configuration and change management standard
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Configuration and change management approach
The Cloud configuration for both live and any development instances is administered from the NMC. Configurations are based on template documents to ensure implementations are standardized across the end-to-end solution. Configuration variables (eg. IP addressing) are managed to enable digital resources to be assigned efficiently without duplication. All documents and configurations are version controlled with changes approved, accounted for and audited by user/date/reason. Configurations are stored with separation between the configurations for each customer’s specific solutions. Change management includes but is not limited to: Change requests with corresponding impact assessments, implementation and corresponding change monitoring and Authorisation for change
Vulnerability management type
Supplier-defined controls
Vulnerability management approach
We operate continuous vulnerability management. We use both technical scans; with Microsoft Baseline Security Analyser and Panda Adaptive Defense 360, and prevention; with hardware and software firewalls, file access controls, limited administrator rights, staff training and physical security. All company activities are appraised for risks, with potential vulnerabilities assessed and categorized as either manageable risk or deemed unacceptable. Technical vulnerability management across the system will be conducted using Cloud applications such as AWS GuardDuty and AWS CloudTrail. These services alert our 24/7 NMC team who will immediately cease the vulnerability and highlight to the customer.
Protective monitoring type
Supplier-defined controls
Protective monitoring approach
Technical protective monitoring will be designed in house by our architects to enable the managed service to use Cloud applications such as CloudWatch, AWS Shield plus and AWS WAF. These services alert our 24/7 NMC team who will immediately cease the vulnerability and highlight to the customer. In the event of an incident being identified or being notified of an IP address/instance compromise by the customer, cloud accounts or virtual private clouds shall be removed and reinstated within ~1hr utilizing existing configurations and saved AMI's. Close liaison with the customer will take place throughout the process.
Incident management type
Supplier-defined controls
Incident management approach
Incident Management for both common issues and ad hoc problems, whether identified proactively by the NMC or reported directly from an end user, utilizes GRC's existing ITIL compliant processes. Users are able to contact GRC support staff directly via freephone 24x7, whether in the NMC during business hours or on-call out of hours. Contact is regularly maintained through to incident resolution and user approved closure via phone, webchat and email. Service Review Meetings with the GRC Account Team, including consolidated incident reports, occur regularly, with a frequency as agreed with each customer.
