Acceptable Use Policy

General use and ownership 1.

While SA desires to provide a reasonable level of privacy, users should be aware that the data they create on the corporate systems remains the property of SA. Because of the need to protect SA’s network, management cannot guarantee the confidentiality of information stored on any network device belonging to SA.

2.

Any information transmitted over SA’ s networks that has not been specifically identified as the property of other parties is by default treated as belonging to SA.

3.

Unauthorized access, disclosure, duplication, modification, diversion, destruction, loss, misuse, or theft of any information is strictly prohibited.

4.

Users 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 the absence of such policies, users should be guided by departmental policies on personal use, and if there is any uncertainty, users should consult their supervisor or manager.

5.

For security and network maintenance purposes, authorized individuals within SA may monitor equipment, systems and network traffic at any time.

6.

SA reserves the right to audit networks and systems on a periodic basis to ensure compliance with this policy.

7.

Access to Internet and email may be restricted if the bandwidth does not support the volume or in case of any misuse.

Security and proprietary information 1.

The user interface for information contained on Internet/Intranet/Extranet-related systems should be classified as either confidential or not confidential, as defined by corporate Confidentiality guidelines. Examples of confidential information include but are not limited to: company private, corporate strategies, competitor sensitive, trade secrets, specifications, customer lists, and research data. Users should take all necessary steps to prevent unauthorized access to this information.

2.

Users are advised to keep passwords secure and not to share user account related information with others. Authorized users are responsible for the security of their respective passwords and accounts. System level passwords and user level passwords should be changed in accordance with the Access control and Password policy.

3.

All PCs, laptops and workstations should be secured with a password-protected screensaver with the automatic activation feature set, when the host will be unattended. Refer to the Clear Desk Clear Screen policy.

4.

Use encryption of information, as feasible and applicable as per relevant IS policies.

5.

Because information contained on portable computers is especially vulnerable, special care should be exercised. Protect laptops in accordance with the Laptop Security Tips.

6.

Postings by users from a SA email address to newsgroups should contain a disclaimer stating that the opinions expressed are strictly their own and not necessarily those of SA, unless posting is in the course of business duties.

7.

All hosts used by the user that are connected to the SA Internet/Intranet/Extranet, whether owned by the user or SA, shall be continually executing approved virus-scanning software with a current virus database, unless overridden by departmental or group policy.
