The purpose of this policy is to establish standards for the base configuration of internal server equipment that is owned and/or operated by Anchor Systems. Effective implementation of this policy will minimise unauthorised access to Anchor Systems server equipment.
This policy applies to server equipment owned and/or operated by Anchor Systems, and to servers registered under any Anchor Systems-owned internal network domain. This policy is specifically for equipment on the internal Anchor Systems network.
General Configuration Guidelines
Operating System configuration should be in accordance with approved internal guidelines.
- Services and applications that will not be used must be disabled where practical.
- Access to services should be logged and/or protected through access-control methods such as TCP Wrappers, if possible.
- The most recent security patches must be installed on the system as soon as practical, the only exception being when immediate application would interfere with business requirements.
- Trust relationships between systems are a security risk, and their use should be avoided. Do not use a trust relationship when some other method of communication will do.
- Security principles of least required access to perform a function is employed where possible.
- Root access will not be used when a non- privileged account will do.
- If a methodology for secure channel connection is available (i.e., technically feasible), privileged access must be performed over secure channels, (e.g., encrypted network connections using SSH or IPSec).
- Servers are physically located in an access-controlled environment.
- Servers are specifically prohibited from operating from uncontrolled cubicle areas.
All security-related events on critical or sensitive systems must be logged and audit trails saved as follows:
- All security related logs will be kept online for a minimum of 1 week.
- Daily incremental tape backups will be retained for at least 1 week.
- Weekly full tape backups of logs will be retained for at least 1 month.
- Security-related events will be reported to Anchor Systems security personel. Corrective measures will be prescribed as needed. Security-related events include, but are not limited to:
- Evidence of unauthorized access to privileged accounts
- Anomalous occurrences that are not related to specific applications on the host.
Audits will be performed on a regular basis by authorized organizations within Anchor Systems. Every effort will be made to prevent audits from causing operational failures or disruptions.
Any employee found to have violated this policy may be subject to disciplinary action, up to and including termination of employment.
Server: For purposes of this policy, a Server is defined as an internal Anchor Systems Server. Desktop machines and Lab equipment are not relevant to the scope of this policy.
