Information Security Acceptable Use Policy
The Development Manager (TDM) ’s intentions for publishing an Acceptable Use Policy are not to impose restrictions that are contrary to TDM’s established culture of openness, trust and integrity. TDM is committed to protecting its team members, 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, WWW browsing, and FTP, are the property of TDM. 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 TDM employee and stakeholder who deals with information and/or information systems. It is the responsibility of every computer user to know these guidelines, and to conduct their activities accordingly.
The purpose of this policy is to outline the acceptable use of computer equipment at TDM. These rules are in place to protect the employee and TDM assets which include confidential data handled by the Company. Inappropriate use exposes TDM to risks including virus attacks, compromise of network systems and services, and legal issues.
This policy applies to the use of information, electronic and computing devices, and network resources to conduct TDM business or interact with internal networks and business systems, whether owned or leased by TDM, the employee, or a third party.
All employees, contractors, consultants, temporary, and other workers at TDM and its subsidiaries are responsible for exercising good judgment regarding appropriate use of information, electronic devices, and network resources in accordance with TDM policies, procedures and local laws and regulation. Exceptions to this policy are documented in section “Policy Compliance”
This policy applies to employees, contractors, consultants, temporaries, and other workers at TDM, including all staff affiliated with third parties. This policy applies to all equipment that is owned or leased by TDM.
4.1 General Use and Ownership
• TDM proprietary information and confidential information, stored on paper, electronic and computing devices, whether owned or leased by TDM, the employee or a third party, remains the sole property of TDM. You must ensure through legal or technical means that proprietary information is protected in accordance with the Data Protection Act.
• You have a responsibility to promptly report the theft, loss or unauthorised disclosure of TDM proprietary and/or confidential information.
• You may access, use or share TDM’s proprietary and/or confidential information only to the extent it is authorised and necessary to fulfill your assigned job duties.
• Employees are responsible for exercising good judgment regarding the reasonableness of personal use. Individual departments are responsible for creating guidelines concerning personal use of Internet/Intranet/Extranet systems. In any case, employees should be guided by TDM’s policies on use of equipment and data protection, such as Data protection policy, computers and electronic communications policy, confidentiality policy, etc. If there is any uncertainty, employees should consult their supervisor or manager.
• For security and network maintenance purposes, authorised individuals within TDM may monitor equipment, systems and network traffic at any time, per TDM’s monitoring policy.
• TDM reserves the right to audit networks and systems on a periodic basis to ensure compliance with this policy.
4.2 Security and Proprietary Information
• All mobile and computing devices that connect to the internal network must comply with the Password Policy.
• System level and user level passwords must comply with the password guidance given by management team and the TDM systems team leader. Providing access to another individual, either deliberately or through failure to secure its access, is prohibited.
• All computing devices must be secured with a password-protected screensaver with the automatic activation feature set to 10 minutes or less. You must lock the screen or log off when the device is unattended.
• Postings by employees from a TDM email address to newsgroups must comply with General Data Protection Regulations and should contain a disclaimer stating that the opinions expressed are strictly their own and not necessarily those of TDM unless posting is in the course of business duties and when authorised by line manager.
• Employees must use extreme caution when opening e-mail attachments received from unknown senders, or from known senders where the email communication is deemed to be suspicious, as this may contain malware.
• When employees are connecting to an unknown network with their TDM devices or to look at TDM systems, they must ensure it is safe to do so and that the security of the systems remain safe and secure.
• If employees are ever asked to logging into new systems and enter passwords etc, this must be done just with the right trusted people and if in doubt should seek clearance from managers. Do not act on an assumption.
4.3 Unacceptable Use
