INFORMATION SECURITY POLICY
1. Introduction
This policy document encompasses all aspects of security surrounding confidential RhoKit information and must be distributed to all RhoKit employees.
All RhoKit 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
RhoKit does not handle sensitive cardholder information on any basis.
RhoKit requires no access and has no access to cardholder data.
RhoKit handles sensitive merchant information daily, including but not limited to the following: know your customer information (KYC), certified copies of utility bills and passports, merchant financial information and merchant financial results.
Sensitive Information must have adequate safeguards in place to protect it, to protect merchant privacy, to ensure compliance with various regulations and to guard the future of the organisation. RhoKit 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 information so that we can meet these customer and other stakeholder promises.
Employees handling sensitive data should ensure to proactively practice the following:
● Handle information in a manner that fits with its sensitivity
● Limit personal use of RhoKit information and telecommunication systems and ensure such use does not interfere with your job performance
● RhoKit 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 email, internet and other RhoKit resources to engage in any action that is offensive, threatening, discriminatory, defamatory, slanderous, pornographic, obscene, harassing or illegal;
● Do not disclose personal or any RhoKit personnel information unless authorised
● Protect sensitive information
● Keep passwords and accounts secure
● Request approval from management prior to establishing any new software or hardware, third party connections, etc.
● Do not install unauthorised software or hardware, including modems and wireless access unless you have explicit management approval

● If you are unclear about any of the policies detailed herein you should seek advice and guidance from your line manager
● RhoKit does not handle sensitive cardholder information on any basis
● RhoKit requires no and has no access to cardholder data
3. Acceptable Use Policy
The Management’s intentions for publishing an Acceptable Use Policy are not to impose restrictions that are contrary to RhoKit’s established culture of openness, trust and integrity.
Management is committed to protecting the employees, partners and RhoKit from illegal or damaging actions by individuals, either knowingly or unknowingly.
RhoKit does not manage, maintain, supply, offer, sell, handle, service, repair or deal in any way with Point of Sale (POS) devices and Personal Identification Number (PIN) entry devices.
RhoKit will maintain an approved list of technologies and devices and personnel with access to such devices as detailed in Appendix B. In addition:
● Employees are responsible for exercising good judgement regarding the reasonableness of personal use
● Employees should ensure that they have appropriate credentials and are authenticated for the use of technologies
● Employees should take all necessary steps to prevent unauthorised access to confidential data which includes their own personal data
● Employees should ensure that technologies are set-up, started and used in acceptable network locations
● Keep passwords secure and do not share accounts unless as explicitly permitted
● Authorised users are responsible for the security of their passwords and accounts
● All PCs, laptops and workstations should be secured with a password protected screen saver with the automatic activation feature at most after 5 minutes
● All POS and PIN entry devices should be appropriately protected and secured so they cannot be tampered or altered
● Because information contained on portable computers is especially vulnerable, special care should be exercised with both password protection and safe handling of equipment
● Postings by employees from a RhoKit email address to newsgroups should contain a disclaimer stating that the opinions expressed are strictly their own and not necessarily those of the RhoKit, unless posting is in the course of business duties
● Employees must use extreme caution when opening email attachments received from unknown senders which may contain viruses, e-mail bombs, or Trojan horse code
RhoKit does not manage, maintain, supply, offer, sell, handle, service, repair or deal in any way with any POS devices and PIN entry devices.
4. Disciplinary Action
Violation of the standards, policies and procedures presented in this document by an employee will result in disciplinary action, from warnings or reprimands up to and including termination of employment.
Claims of ignorance, negligence, good intentions or poor judgement will not be used as excuses for non-compliance.
5. Protect Stored Data
● All sensitive data stored and handled by RhoKit and its employees must be securely protected against unauthorised use at all times
● Any sensitive data that is no longer required by RhoKit for business reasons must be discarded in a secure and irrecoverable manner
● If there is no specific need to see the full Permanent Account Number (PAN), it has to be masked when displayed
● PAN’S which are not protected as stated above should not be sent to an outside network via end-to-end user messaging technologies like chats, WhatsApp, ICQ messenger, etc.
● It is strictly prohibited to possess and store for any reason:
o The contents of the payment card magnetic stripe (track data) on any media whatsoever
o The CVV/CVC (the 3 or 4 digit number on the signature panel, or on the reverse of the payment card) on any media whatsoever
o The PIN or the encrypted PIN Block under any circumstance
6. Information Classification

● Visitors and RhoKit personnel including employees and consultants should keep passwords secure and at no time share accounts
● Visitors must always be escorted by a trusted employee when in areas that hold sensitive information
● Procedures must be in place to help all personnel easily distinguish between employees and Visitors, especially in areas where sensitive data is accessible
o An Employee refers to full-time and part-time employees, temporary employees and personnel, and consultants who are permanently based on RhoKit sites
o A Visitor is defined as a vendor, guest of an employee, service personnel, or anyone who needs to enter the premises for a short duration, usually not more than one day
● Authorised users are responsible for the security of their passwords and accounts as well as to other personnel to whom they delegated authorities, as permitted by management

● Data must never be sent over the internet via email, instant chat or any other end user technologies unless explicitly prescribed by management
● If there is a business justification to send data via email or via the internet or any other modes then it should be done after authorization and by using a strong encryption mechanism (e.g. AES encryption, PGP encryption, SSH, SSL, TLS, IPSEC, GSM, GPRS, Wireless technologies etc.)
● The transportation of media containing sensitive data to another location must be authorised by management, logged and inventoried before leaving the premises. Only secure courier services may be used for the transportation of such physical media. The status of the shipment should be monitored until it has been delivered to its new location (such as a tracking number) and verified by the recipients in writing
10. Disposal of Stored Data
● All data must be securely disposed of when no longer required by RhoKit, regardless of the media or application type on which it is stored
● An automatic process must exist to permanently delete on-line data, when no longer required
● All hard copies of data must be manually destroyed as when no longer required for valid and justified business reasons. A quarterly process must be in place to confirm that all non-electronic data has been appropriately disposed of in a timely manner
● RhoKit will have procedures for the destruction of hard copy (paper) materials. These will require that all hard copy materials are cross-cut shredded, incinerated or pulped so they cannot be reconstructed
● RhoKit will have documented procedures for the destruction of electronic media. These will require:
o All data on electronic media must be rendered unrecoverable when deleted e.g. through degaussing or electronically wiped using military grade secure deletion processes or the physical destruction of the media
o If secure wipe programs are used, the process must define the industry accepted standards followed for secure deletion
o All data awaiting destruction must be held in lockable storage containers clearly marked To Be Shredded. Access to these containers must be restricted
11. Security Awareness and Procedures
● The policies and procedures outlined below must be incorporated into RhoKit practice to maintain a high level of security awareness. The protection of sensitive data demands regular training of all employees and contractors:
o Review handling procedures for sensitive information and hold periodic security awareness meetings to incorporate these procedures into day to day RhoKit practice
o Distribute this security policy document to all RhoKit employees to read. It is required that all employees confirm that they understand the content of this security policy document by signing an acknowledgement form (see Appendix A)
o All employees that handle sensitive data will undergo background checks (such as criminal and credit record checks, within the limits of the local law) before they commence their employment with the RhoKit
o All third parties with access to credit card account numbers are contractually obligated to comply with card association security standards (PCI/DSS)
● RhoKit security policies must be reviewed annually and updated as needed
12. Network Security and Firewalls
● Firewalls must be implemented at each internet connection and any external or Visitors zone with the internal RhoKit network
● A network diagram detailing all the inbound and outbound connections must be maintained and reviewed every 6 months
● A firewall and router configuration document must be maintained which includes a documented list of services, protocols and ports including a business justification
● Firewall and router configurations must restrict connections between untrusted networks and any systems in the data environment.
● Stateful Firewall technology must be implemented where the internet enters RhoKit network to mitigate known and on-going threats. Firewalls must also be implemented to protect local network segments and the information technology resources attached to those segments such as the business network, and open network
● All inbound and outbound traffic must be restricted to that which is required for the data environment
● All inbound network traffic is blocked by default, unless explicitly allowed and the restrictions have to be documented.
● All outbound traffic has to be authorised by management (e.g. what are the white listed category of sites that can be visited by the employees) and the restrictions have to be documented
● RhoKit will have firewalls between any wireless networks and the data environment
● RhoKit will quarantine wireless users into a Visotors Zone (or De-militarised Zone DMZ, in LAN parlance), where they will be authenticated and fire walled as if they were coming in from the internet
● Disclosure of private IP addresses to external entities must be authorised
● 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 month basis to ensure validity and the firewall is to have a clean up rule at the bottom of the rule base
● RhoKit has to quarantine wireless users into a DMZ, where they were authenticated and fire walled as if they were coming in from the internet
● No direct connections from the internet to the 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 RhoKit 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 accepted 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 RhoKit 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 be set appropriately on all 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 data must have a unique ID (User Id)
● All users must use a password to access RhoKit network or any other electronic resources
● All User ID’s for terminated users must be deactivated or removed immediately
● Any User ID will be locked out if there are more than 3 unsuccessful attempts. A locked out 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 set-up 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, SSL 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:
o Be as long as possible (never shorter than 6 characters)
o Include mixed-case letters, if possible
o Include digits, syntax and punctuation marks, if possible
o Not be based on any personal information
o Not be based on any dictionary word, in any language
● If an operating system other than Linux and FreeBSD without embedded 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 RhoKit. The preferred applications to use include CLAMAV, SOPHOS & COMODO Anti-Virus software, which must be configured to retrieve the latest updates to the antiviral program automatically on a daily basis. The Anti-Virus should have periodic scanning enabled for all the systems
● The Anti-Virus software in use should be capable of detecting all known types of malicious software (Viruses, Trojans, adware, spyware, worms and rootkits)
● All removable media (for example USB thumb drives and others) should be scanned for viruses before being used
● All the logs generated from the Anti-Virus solutions have to be retained as per legal, regulatory, and contractual requirements or at a minimum of PCI DSS requirement 10.7 of 3 months online and 1 year offline
● Master installations of the Anti-Virus software should be set-up for automatic updates and periodic scans
● End users must not be able to modify any settings or alter the Anti-Virus software
● Email with attachments coming from suspicious or unknown sources should not be opened. All such emails and their attachments should be deleted from the mail system as well as from the trash bin. No one should forward any email, which they suspect may contain a virus or other malicious software.
15. Patch Management Policy
● All workstations, servers, software, system components etc. owned by RhoKit must have up-to-date system security patches installed to protect the asset from known vulnerabilities
● Wherever 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 the change control process
● Any exceptions to this process have to be documented.
16. Remote Access Policy
● It is the responsibility of RhoKit employees, contractors, vendors and agents with remote access privileges to RhoKit corporate network to ensure that their remote access connection is given the same consideration as the user’s on-site connection to RhoKit
● 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 RhoKit 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 set-up to be disconnected automatically after 30 minutes or less of inactivity
● All hosts that are connected to RhoKit internal networks via remote access technologies will be monitored on a regular basis
● All remote access accounts used by vendors or third parties will be reconciled at regular interviews and the accounts will be revoked if there is no further business justification
● Vendor accounts with access to RhoKit 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
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, RhoKit 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 RhoKit by internal staff or a third 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 the PCI Security Standards Council, PCI-SSC. Scans conducted after network changes may be performed by RoKit internal staff. The scan process should include re-scans until passing results are obtained
18. Configuration Standards
● Information systems that process, transmit or store 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 RhoKit required standards before being placed on the network as specified in RhoKit 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 RhoKit 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 RhoKit 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 RhoKit 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 depending 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
● 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
● All changes shall be approved prior to implementation. Approval of changes shall be based on formal acceptance criteria (e.g. 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
● 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
20. Audit And Log Review
This procedure covers all logs generated for systems within the data environment, based on the flow of data over the RhoKit network, including the following components:
● Operating System Logs (Event Logs and other logs)
● Database Audit Logs

● Any modification to system files
● Actions taken by any individual with Administrative privileges
● Any user access to audit trails
● Any creation or deletion of system-level objects installed by DOS, Windows and MacOS. (Almost all system-level objects run with administrator privileges, and some can be abused to gain administrator access to a system.)
For any suspicious event confirmed, the following must be recorded on the Log Review Form, and RhoKit CISO informed:
● User Identification
● Event Type
● Date and Time
● Success or Failure indication
● Event Origination (e.g. IP address and/or User ID)
● Reference to the data, system component or resource affected
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 RhoKit information technology systems and trusted contractor sites processing RhoKit data.
Each phase of the SDLC is mapped with security activities, as explained below:
● Design Phase
● Identify Design Requirements from a Security Perspective
● Architecture and Design Reviews
● Threat Modelling
● Coding Phase
● Coding Best Practices
● Perform Static Analysis
● Testing Phase including User Acceptance Testing
● Vulnerability Assessment
● Fuzzing
● Deployment Phase
● Server Configuration Review
● Network Configuration Review
Development of code shall be checked and validated with the most current versions of RhoKit 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 RhoKit 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 management
In practice Code Developers will:
● 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 used by RhoKit. Additionally, it should be noted for each mitigation what measures will be taken.
Examples below should help frame future testing:
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. If any sign of trouble is detected, 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 organisations ecosystem
Key staff involved in the project by the organisation will be listed:
● Technical Project Manager
● Chief Information Security Officer (CISO)
● Chief Information Officer or Chief Financial Officer as alternative
● Head of Communications responsible for web sites www.rhokit.com and legacy sites such as www.rokit-it.com
● External intrusion tests will be performed remotely from the vendor’s premises
● Internal intrusion tests will be conducted in the RhoKit offices and other affiliate organisations

● The Audit team must have access to the Organisation’s network. It must manage access permissions to the building early enough to ensure that the audit team can access it without problems during the planning period.
● All the tests will be conducted from the equipment owned by the audit team so no equipment for the execution of the tests is required. The only requirement in this regard will be to have an active network connection for each member of the audit team. Those connections must provide access to the target network segment in every case.
● If an incident occurs during the execution of the tests that have an impact on the systems or services of the organisation, the incident should be brought immediately to the attention of those responsible for incident management in the project.
It should be noted that in order to comply with PCI-DSS the scope of the tests should include at minimum, but not limited to the following:
● All systems and applications that are part of the perimeter of the data environment card (CDE)
Example #2:
● Systems included in the scope:
o System 1: IP: System: System Description RhoKit Internal
o System 2: IP: System: System Description WiFi network and access to RhoKit internal.
● Applications included in the scope:
o Application 1: URL: Description of the application.
● Systems excluded from the scope:
o System 5: IP: System: System Description
o System 6: IP: System: System Description
● Applications excluded from the scope:
o Application 3: URL: Description of the application.
● Technical tests must follow the Open Source Security Testing Methodology Manual (OSSTMM).
All tests must be conducted at network, system and application level and must ensure that at least identifies any vulnerabilities documented by OWASP and SANS, as well as those identified in the PCI-DSS standard v3:
● Injections: Code, SQL, OS commands, LDAP , XPath , etc.
● Buffer overflows
● Insecure storage of cryptographic keys
● Insecure Communications
● Improper error handling
● Cross-site scripting (XSS)
● Control of inappropriate access
● Cross-site request forgery (CSRF)
● Broken authentication and incorrectly session management
● Any other vulnerability considered High Risk by the organisation
For all findings or vulnerabilities identified during the tests carried out sufficient evidence to prove the existence of the same will be generated and documented. The format of the evidence can be variable in each case, screen capture, raw output of security tools, photographs, paper documents, etc.
As a result of tests performed should generate a document containing at least the following sections:
● Introduction.
● Executive Summary
● Methodology
● Identified vulnerabilities
● Recommendations for correcting vulnerabilities
● Conclusions
● Evidence
23. Incident Response Plan
A Security Incident means any incident (accidental, intentional or deliberate) relating to our 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 RhoKit’s reputation with a customer.
The Incident response plan has to be tested once annually. Copies of this incident response plan are to be made available to all relevant staff members. RhoKit’s management is to take steps to ensure that staff understand it and what is expected of them.
Staff and employees of RhoKit will be expected to report to the security officer for any security related issues
RhoKit PCI security incident response plan is as follows:
● Each department must report an incident to the Chief Information Security Officer (CISO) or to another member of the PCI Response Team
● That member of the team receiving the report will advise the PCI Response Team of the incident
● The PCI Response Team will investigate the incident and assist the potentially compromised department in limiting the exposure of data and in mitigating the risks associated with the incident
● 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
● The PCI Response Team will determine if policies and processes need to be updated to avoid or mitigate impacts of a similar incident in the future, and whether additional safeguards are required in the environment where the incident occurred, or for the institution
● If an unauthorised wireless access point or other device is identified or detected as part of the quarterly test, such an incident in each instance must 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
● A department that reasonably believes it may have an account breach, or a breach of data or of systems related to the PCI environment in general, must inform RhoKit 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
