This Information Security Policy is intended to protect Castle’s employees, partners and the company from illegal or damaging actions by individuals, either knowingly or unknowingly.
Internet/Intranet/Extranet-related systems, including but not limited to computer equipment, software, operating systems, storage media, network accounts providing electronic mail, web browsing, and file transfers, are the property of Castle. These systems are to be used for business purposes in serving the interests of the company, and of our clients and customers in the course of normal operations.
Effective security is a team effort involving the participation and support of every Castle employee or contractor who deals with information and/or information systems. It is the responsibility of every team member to read and understand this policy, and to conduct their activities accordingly.
The purpose of this policy is to communicate our information security policies and outline the acceptable use and protection of Castle’s information and assets. These rules are in place to protect customers, employees, and Castle. Inappropriate use exposes Castle to risks including virus attacks, compromise of network systems and services, and legal and compliance issues.
The Castle “Information Security Policy” is comprised of this policy and all Castle policies referenced and/or linked within this document.
This policy applies to the use of information, electronic and computing devices, and network resources to conduct Castle business or interact with internal networks and business systems, whether owned or leased by Castle, the employee, or a third party. All employees, contractors, consultants, temporary, and other workers at Castle and its subsidiaries are responsible for exercising good judgment regarding appropriate use of information, electronic devices, and network resources in accordance with Castle policies and standards, and local laws and regulations.
This policy applies to employees, contractors, consultants, temporaries, and other workers at Castle, including all personnel affiliated with third parties. This policy applies to all Castle-controlled company and customer data as well as all equipment, systems, networks and software owned or leased by Castle.
