Security governance

Named board-level person responsible for service security
Security governance certified
Security governance approach
Herlayer has been developed to run on Amazon servers, who are a tier 1 Cloud service provider. Working alongside their Cyber Security Governance and their certification ISO 27001:2013, the world’s most recognised security standard. Sherlayer security risk assessment identifies the various information assets that can be affected by a cyber-attack. We continually review the risk environment to detect any changes in the context of Sherlayer and the provision of this service.
Information security policies and processes
Sherlayer has a multi-type level security policy. Primary login of the Amazon Cloud provider is held by two of the current Directors of Sherwood Systems. This password is changed every three months and only the two directors / Shareholders have the amended password. If there is a breach in security, then all passwords are changed with 24 hours and there is a full investigation to where the breach has come from. If any client’s data is compromised, then that client is notified within 6 hours. If the security breach has the potential to affect all clients, then all client will be notified within 24 hours.

Operational security

Configuration and change management standard
Supplier-defined controls
Configuration and change management approach
All changes to all components are tracked using a private Git repository (Bitbucket) and code reviewed for security impacts, all changes must pass a set of automated tests ran by the check-in service to ensure optimal service function. All new features and changes are manually tested from aspects of user experience and security.
Vulnerability management type
Supplier-defined controls
Vulnerability management approach
Vulnerabilities are escalated as part of the SLA, these are deemed as a major incident. Patches can be instantaneously provisioned to all users. Constant review of technologies to include php, MySQL, apache, composer, grunt, Linux(ubuntu).
Protective monitoring type
Supplier-defined controls
Protective monitoring approach
Emails are sent out to a board level director when a server is accessed directly if this is unplanned we are able to un-authenticate the unknown user. In this case, the AUTH certificate will be regenerated. We routinely check MySQL admin access logs, super admin control panel access logs and hosting control panel access history. This occurs on a weekly basis. At least one member of staff is on standby to respond to serious incidents 24/7.
Incident management type
Supplier-defined controls
Incident management approach
Online support log available to all users. All calls are put onto computerised support help desk and are assessed accordingly, in relation to security level, which then determines the SLA we must meet. We follow up with users when any update is available regarding the incident.
