Information Security Policy

1.     Introduction

This Policy Document encompasses all aspects of security surrounding confidential company information and must be distributed to all company employees. All company employees must read this document in its entirety and sign the form confirming they have read and understand this policy fully. This document will be reviewed and updated by Management on an annual basis or when relevant to include newly developed security standards into the policy and distribute it all employees and contracts as applicable.

2.     Information Security Policy

The Company handles sensitive cardholder information daily.  Sensitive Information must have adequate safeguards in place to protect them, to protect cardholder privacy, to ensure compliance with various regulations and to guard the future of the organisation.

The Company commits to respecting the privacy of all its customers and to protecting any data about customers from outside parties.  To this end management are committed to maintaining a secure environment in which to process cardholder information so that we can meet these promises.

Employees handling Sensitive cardholder data should ensure:

• Handle Company and cardholder information in a manner that fits with their sensitivity;
• Limit personal use of the Company information and telecommunication systems and ensure it doesn’t interfere with your job performance;
• The Company reserves the right to monitor, access, review, audit, copy, store, or delete any electronic communications, equipment, systems and network traffic for any purpose;
• Do not use e-mail, internet and other Company resources to engage in any action that is offensive, threatening, discriminatory, defamatory, slanderous, pornographic, obscene, harassing or illegal;
• Do not disclose personnel information unless authorised;
• Protect sensitive cardholder information;
• Keep passwords and accounts secure;
• Request approval from management prior to establishing any new software or hardware, third party connections, etc.;

• The company will have firewalls between any wireless networks and the cardholder data environment.
• the company will quarantine wireless users into a DMZ, where they will be authenticated and firewalled as if they were coming in from the Internet.
• Disclosure of private IP addresses to external entities must be authorized.
• A topology of the firewall environment has to be documented and has to be updated in accordance to the changes in the network.
• The firewall rules will be reviewed on a six months basis to ensure validity and the firewall has to have clean up rule at the bottom of the rule base.
• the Company have to quarantine wireless users into a DMZ, where they were authenticated and firewalled as if they were coming in from the Internet.
• No direct connections from Internet to cardholder data environment will be permitted. All traffic has to traverse through a firewall.

 

13.   System and Password Policy

All users, including contractors and vendors with access to the Company systems, are responsible for taking the appropriate steps, as outlined below, to select and secure their passwords.

• A system configuration standard must be developed along industry acceptable hardening standards (SANS, NIST, ISO)
• System configurations should be updated as new issues are identified (as defined in PCI DSS requirement 6.1)
• System configurations must include common security parameter settings
• The systems configuration standard should be applied to any news systems configured.
• All vendor default accounts and passwords for the systems have to be changed at the time of provisioning the system/device into the Company network and all unnecessary services and user/system accounts have to be disabled.
• All unnecessary default accounts must be removed or disabled before installing a system on the network.
• Security parameter settings must me set appropriately on System components
• All unnecessary functionality (scripts, drivers, features, subsystems, file systems, web servers etc.,) must be removed.
• All unnecessary services, protocols, daemons etc., should be disabled if not in use by the system.
• Any insecure protocols, daemons, services in use must be documented and justified.
• All users with access to card holder data must have a unique ID.
• All user must use a password to access the company network or any other electronic resources
• All user ID’s for terminated users must be deactivated or removed immediately.
• The User ID will be locked out if there are more than 5 unsuccessful attempts. This locked account can only be enabled by the system administrator. Locked out user accounts will be disabled for a minimum period of 30 minutes or until the administrator enables the account.
• All system and user level passwords must be changed on at least a quarterly basis.
• A minimum password history of four must be implemented.
• A unique password must be setup for new users and the users prompted to change the password on first login.
• Group, shared or generic user account or password or other authentication methods must not be used to administer any system components.
• Where SNMP is used, the community strings must be defined as something other than the

Standard defaults of "public," "private" and "system" and must be different from the passwords used to log in interactively.

• All non-console administrative access will use appropriate technologies like ssh,vpn etc or strong encryption is invoked before the administrator password is requested
• System services and parameters will be configured to prevent the use of insecure technologies like telnet and other insecure remote login commands
• Administrator access to web based management interfaces is encrypted using strong cryptography.
• The responsibility of selecting a password that is hard to guess generally falls to users. A strong password must:

1. Be as long as possible (never shorter than 6 characters).
2. Include mixed-case letters, if possible.
3. Include digits and punctuation marks, if possible.
4. Not be based on any personal information.
5. Not be based on any dictionary word, in any language.

• If an operating system without security features is used (such as DOS, Windows or MacOS), then an intruder only needs temporary physical access to the console to insert a keyboard monitor program. If the workstation is not physically secured, then an intruder can reboot even a secure operating system, restart the workstation from his own media, and insert the offending program.
• To protect against network analysis attacks, both the workstation and server should be cryptographically secured. Examples of strong protocols are the encrypted Netware login and Kerberos.

14.     Anti-virus policy

• All machines must be configured to run the latest anti-virus software as approved by the Company. The preferred application to use is XXXX Anti-Virus software, which must be configured to retrieve the latest updates to the antiviral program automatically on a daily basis. The antivirus should have periodic scanning enabled for all the systems.
• The antivirus software in use should be cable of detecting all known types of malicious software (Viruses, Trojans, adware, spyware, worms and rootkits)
• All removable media (for example floppy and others) should be scanned for viruses before being used.
• All the logs generated from the antivirus solutions have to be retained as per legal/regulatory/contractual requirements or at a minimum of PCI DSS requirement 10.7 of 3 months online and 1 year offline.
• Master Installations of the Antivirus software should be setup for automatic updates and periodic scans
• End users must not be able to modify and any settings or alter the antivirus software

15.     Patch Management Policy

• All Workstations, servers, software, system components etc. owned by the Company must have up-to-date system security patches installed to protect the asset from known vulnerabilities.
• Where ever possible all systems, software must have automatic updates enabled for system patches released from their respective vendors. Security patches have to be installed within one month of release from the respective vendor and have to follow the process in accordance with change control process.
• Any exceptions to this process have to be documented.

16.    Remote Access policy

• It is the responsibility of the Company employees, contractors, vendors and agents with

remote access privileges to the Company’s corporate network to ensure that their remote

access connection is given the same consideration as the user's on-site connection to the Company.

• Secure remote access must be strictly controlled. Control will be enforced by two factor authentication via one-time password authentication or public/private keys with strong pass-phrases.
• Vendor accounts with access to the company network will only be enabled during the time period the access is required and will be disabled or removed once access is no longer required.
• Remote access connection will be setup to be disconnected automatically after 30 minutes of inactivity

17.  Vulnerability Management Policy

• All the vulnerabilities would be assigned a risk ranking such as High, Medium and Low based on industry best practices such as CVSS base score.
• As part of the PCI-DSS Compliance requirements, the Company will run internal and external network vulnerability scans at least quarterly and after any significant change in the network (such as new system component installations, changes in network topology, firewall rule modifications, product upgrades).
• Quarterly internal vulnerability scans must be performed by the Company by internal staff or a 3rd party vendor and the scan process has to include that rescans will be done until passing results are obtained, or all High vulnerabilities as defined in PCI DSS Requirement 6.2 are resolved.
• Quarterly external vulnerability scans must be performed by an Approved Scanning Vendor (ASV) qualified by PCI SSC. Scans conducted after network changes may be performed by the Company’s internal staff. The scan process should include re-scans until passing results are obtained.

18.    Configuration standards:

• Information systems that process transmit, or store card holder data must be configured in accordance with the applicable standard for that class of device or system. Standards must be written and maintained by the team responsible for the management of the system in conjunction with the Information Security Office.
• All network device configurations must adhere to the Company required standards before being placed on the network as specified in the Company configuration guide. Using this guide, a boilerplate configuration has been created that will be applied to all network devices before being placed on the network.
• Before being deployed into production, a system must be certified to meet the applicable configuration standard
• Updates to network device operating system and/or configuration settings that fall under the Company standards are announced by the Information security Office. Updates must be applied within the time frame identified by the Information security Office.
• Administrators of network devices that do not adhere to the Company standards (as identified via a previous exception) must document and follow a review process of announced vendor updates to operating system and/or configuration settings.  This process must include a review schedule, risk analysis method and update method.
• All network device configurations must be checked annually against the configuration boilerplate to ensure the configuration continues to meet required standards.
• Where possible, network configuration management software will be used to automate the process of confirming adherence to the boilerplate configuration.
• For other devices an audit will be performed quarterly to compare the boilerplate configuration to the configuration currently in place.
• All discrepancies will be evaluated and remediated by Network Administration.

 

19.  Change control Process

 

• Changes to information resources shall be managed and executed according to a formal change control process. The control process will ensure that changes proposed are reviewed, authorised, tested, implemented, and released in a controlled manner; and that the status of each proposed change is monitored.
• The change control process shall be formally defined and documented. A change control process shall be in place to control changes to all critical company information resources (such as hardware, software, system documentation and operating procedures). This documented process shall include management responsibilities and procedures.  Wherever practicable, operational and application change control procedures should be integrated.
• All change requests shall be logged whether approved or rejected on a standardised and central system. The approval of all change requests and the results thereof shall be documented. A documented audit trail, maintained at a Business Unit Level, containing relevant information shall be maintained at all times. This should include change request documentation, change authorisation and the outcome of the change.  No single person should be able to effect changes to production information systems without the approval of other authorised personnel.
• A risk assessment shall be performed for all changes and dependant on the outcome, an impact assessment should be performed.
• The impact assessment shall include the potential effect on other information resources and potential cost implications. The impact assessment should, where applicable consider compliance with legislative requirements and standards.
• All change requests shall be prioritised in terms of benefits, urgency, effort required and potential impact on operations.
• Changes shall be tested in an isolated, controlled, and representative environment (where such an environment is feasible) prior to implementation to minimise the effect on the relevant business process, to assess its impact on operations and security and to verify that only intended and approved changes were made. (For more information see System Development Life Cycle [citation here]).
• Any software change and/or update shall be controlled with version control. Older versions shall be retained in accordance with corporate retention and storage management policies. (For more information see System Development Life Cycle [citation here])
• All changes shall be approved prior to implementation. Approval of changes shall be based on formal acceptance criteria i.e. the change request was done by an authorised user, the impact assessment was performed and proposed changes were tested.
• All users, significantly affected by a change, shall be notified of the change. The user representative shall sign-off on the change. Users shall be required to make submissions and comment prior to the acceptance of the change.
• Implementation will only be undertaken after appropriate testing and approval by stakeholders. All major changes shall be treated as new system implementation and shall be established as a project. Major changes will be classified according to effort required to develop and implement said changes. (For more information see System Development Life Cycle [citation here])
• Procedures for aborting and recovering from unsuccessful changes shall be documented. Should the outcome of a change be different to the expected result (as identified in the testing of the change), procedures and responsibilities shall be noted for the recovery and continuity of the affected areas. Fall back procedures will be in place to ensure systems can revert back to what they were prior to implementation of changes.
• Information resources documentation shall be updated on the completion of each change and old documentation shall be archived or disposed of as per the documentation and data retention policies.
• Specific procedures to ensure the proper control, authorisation, and documentation of emergency changes shall be in place. Specific parameters will be defined as a standard for classifying changes as Emergency changes.
• All changes will be monitored once they have been rolled-out to the production environment. Deviations from design specifications and test results will be documented and escalated to the solution owner for ratification.

21.  Secure Application development

 

• The Secure Application development policy is a plan of action to guide developers’ decisions and actions during the software development lifecycle (SDLC) to ensure software security. This policy aims to be language and platform independent so that it is applicable across all software development projects.
• The adherence to and use of Secure Application Development Coding Policy is a requirement for all software development on the Company information technology systems and trusted contractor sites processing the Company data.
• Each phase of the SDLC is mapped with security activities, as explained below:

 

1. Design

• Identify Design Requirements from security perspective
• Architecture & Design Reviews
• Threat Modelling

 

1. Coding

• Coding Best Practices
• Perform Static Analysis

 

1. Testing

• Vulnerability Assessment
• Fuzzing

 

1. Deployment

• Server Configuration Review
• Network Configuration Review

 

 

• Development of code shall be checked and validated with the most current versions of the Company Coding Standards for Secure Application Development. All code developers shall verify that their code is in compliance with the most recent and approved coding standards and guidelines.
• Only validated code shall be implemented into the Company production environment. A review and validation ensures that code exhibits fundamental security properties to include correctness, predictability, and attack tolerance.

 

Application Code Developers shall:

• Ensure code meets the level of confidence that software is free from exploitable code vulnerabilities, regardless of whether they are already designed into the software or inserted later in its life cycle.
• Ensure code provides predictable execution or justifiable confidence and that the software, when executed, will provide security functionality as intended.
• Coding techniques must address injection flaws particularly SQL injection,buffer overflow vulnerabilities, cross site scripting vulnerabilities, improper access control (insecure direct object reference, failure to restrict URL access, directory traversal etc.,), cross site request forgery (CSRF), broken authentication and session managment
• Never trust incoming data to the system, apply checks to this data.
• Never rely on the client to store sensitive data no matter how trivial.
• Disable Error messages that return any information to the user.
• Use object inheritance, encapsulation, and polymorphism wherever possible.
• Use environment variables prudently and always check boundaries and buffers.
• Applications must validate input to ensure it is well-formed and meaningful.

 

 

 

22.  Penetration testing methodology

 

• In this section should be listed the risks inherent in conducting penetration testing over the information systems of the company. Additionally, it should be noted for each mitigation measures that will be taken. Examples might be:

 

Example 1#

    Risk: Denial of Service in systems or network devices because of the network scans.

    Mitigation measure 1: network scans must be performed in a controlled manner. The start and end of the scan must be notified to responsible personnel to allow monitoring during testing. For any sign of trouble will abort the scan in progress.

    Mitigation measure 2: scanning tools must be configured to guarantee that the volume of sent packets or sessions established per minute does not cause a problem for network elements. In this sense, we must perform the first scans in a very controlled way and a use minimum configuration that may be expanded when is evident that the configuration is not dangerous for network devices or servers in the organization.

23.  Incident Response Plan

 

'Security incident' means any incident (accidental, intentional or deliberate) relating to your communications or information processing systems. The attacker could be a malicious stranger, a competitor, or a disgruntled employee, and their intention might be to steal information or money, or just to damage your company.

 

The Incident response plan has to be tested once annually. Copies of this incident response plan is to be made available to all relevant staff members, and take steps to ensure that they understand it and what is expected of them.

 

Employees of the company will be expected to report to the security officer for any security related issues.

 

The Company PCI security incident response plan is as follows:

 

1. Each department must report an incident to the Information Security Officer (preferably) or to another member of the PCI Response Team.
2. That member of the team receiving the report will advise the PCI Response Team of the incident.
3. The PCI Response Team will investigate the incident and assist the potentially compromised department in limiting the exposure of cardholder data and in mitigating the risks associated with the incident.

4. The PCI Response Team will resolve the problem to the satisfaction of all parties involved, including reporting the incident and findings to the appropriate parties (credit card associations, credit card processors, etc.) as necessary.
5. The PCI Response Team will determine if policies and processes need to be updated to avoid a similar incident in the future, and whether additional safeguards are required in the environment where the incident occurred, or for the institution.
6. If an unauthorised wireless access point or devices is identified or detected as part of the quarterly test this is should be immediately escalated to the Security officer or someone with similar privileges who has the authority to stop, cease, shut down, and remove the offending device immediately.
7. A department that reasonably believes it may have an account breach, or a breach of cardholder information or of systems related to the PCI environment in general, must inform the Company PCI Incident Response Team. After being notified of a compromise, the PCI Response Team, along with other designated staff, will implement the PCI Incident Response Plan to assist and augment departments’ response plans.
