Information security policies and processes
Every manager at every level throughout Connect makes regular reviews of security controls and procedures in their area of responsibility so as to provide and maintain secure working environments for employees and the security of Connect’s assets, including information. They must ensure that sufficient resources are allocated to carry out this policy in their areas of responsibility. Reviews take place to ensure commitment to continual improvement and in order to satisfy applicable requirements for the management of information security. Every individual within the company is expected to work in conjunction with their managers in all aspects of security to ensure that information security controls and procedures are implemented and operated properly and fully. Security incidents must be reported to the managers concerned and to the Connect’s Management Directors. Information security incidents must be reported to the Connect's Security Manager. Major breaches of security must be reported immediately to the Security Manager, who may take charge of investigations or direct what action should be taken.

• New hardware installations
