Server Security Policy

1. Overview

Unsecured and vulnerable servers continue to be a major entry point for malicious threat actors.  Consistent Server installation policies, ownership, and configuration management are all about doing the basics well.

2. Purpose

The purpose of this policy is to establish standards for the base configuration of internal server equipment that is owned and/or operated by eCuras. Effective implementation of this policy will minimize unauthorized access to eCuras proprietary information and technology.

3. Scope

All employees, contractors, consultants, temporary, and other workers at Cisco and its subsidiaries must adhere to this policy. This policy applies to server equipment owned, operated, or leased by Cisco or registered under a Cisco-owned internal network domain.

This policy specifies requirements for equipment on the internal Cisco network. For secure configuration of equipment external to Cisco on the DMZ, see the Internet DMZ Equipment Policy.

4. Policy

4.1  General Requirements

4.1.1        All internal servers deployed at eCuras must be owned by an operational group responsible for system administration. Approved server configuration guides must be established and maintained by each operational group, based on business needs and approved by InfoSec. Operational groups should monitor configuration compliance and implement an exception policy tailored to their environment. Each operational group must establish a process for changing the configuration guides, including review and approval by InfoSec.  The following items must be met:

4.1.2        For security, compliance, and maintenance purposes, authorized personnel may monitor and audit equipment, systems, processes, and network traffic per the Audit Policy.

4.2  Configuration Requirements

4.2.1        Operating System configuration should be in accordance with approved InfoSec guidelines.

4.2.2        Services and applications that will not be used must be disabled where practical.

4.2.3        Access to services should be logged and/or protected through access-control methods such as a web application firewall, if possible.

4.2.4        The most recent security patches must be installed on the system as soon as practical, the only exception being when an immediate application would interfere with business requirements.

4.2.5        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 is sufficient.

4.2.6        Always use standard security principles of least required access to perform a function.  Do not use root when a non-privileged account will do.

4.2.7        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).

4.2.8        Servers should be physically located in an access-controlled environment.

4.2.9        Servers are specifically prohibited from operating from uncontrolled cubicle areas.

4.3  Monitoring

4.3.1        All security-related events on critical or sensitive systems must be logged, and audit trails saved as follows:

4.3.2        Security-related events will be reported to InfoSec, who will review logs and report incidents to IT management. Corrective measures will be prescribed as needed. Security-related events include, but are not limited to:

5. Policy Compliance

5.1  Compliance Measurement

The Infosec team will verify compliance with this policy through various methods, including but not limited to periodic walk-thrus, video monitoring, business tool reports, internal and external audits, and feedback to the policy owner.

5.2  Exceptions

The Infosec team must approve any exception to the policy in advance.

5.3  Non-Compliance

An employee found to have violated this policy may be subject to disciplinary action, up to and including termination of employment.
