| - | ------------------- | + | **C. Integrity Controls**\\ |
| - | **ACCESS CONTROLS**\\ | + | Protection of electronic health information from improper alteration or destruction. \\ |
| - | * Standard user IDs shall be given to each staff whose work entails the need to access or process heath information.\\ | + | I. Implementation specifications:\\ |
| - | * There shall be a three way process for authentication of users: something they know (password), something they have (secure token), and something they are (biometrics).\\ | + | (A) Mechanism to authenticate electronic protected health information (addressable). Mechanisms to corroborate that electronic health information has not been altered or destroyed in an unauthorized manner shall be implemented.\\ |
| - | * Multi-factor authentication shall be implemented, especially for admin and supervisory accounts. | + | (B) Digital signatures (required). Digital signatures shall be used to identify authenticity of the entry in an electronic system.\\ |
| - | * Passwords shall have the following characteristics: minimum of eight characters in length, have an upper case, lower case and special character in it.\\ | + | (C) Sum Verification (required) shall be used to determine if the input data matches the source data.\\ |
| - | * The last user ID that logged in must not be displayed on the log-in screen.\\ | + | (D) Anti-virus software (required). Computers shall have an Industry Standard Antivirus Software with automatic updates turned on. The software shall be configured regularly and automatically download updates for the latest threats.\\ |
| - | * There shall be an automatic screen or keyboard locking after 5 minutes of inactivity.\\ | + | (E) Data storage encryption (required). Data storage and transmission shall be encrypted. For websites, https encryption shall be used. \\ |
| - | + | (F) Transmission encryption (required). Data transmission via wireless networks or the internet shall always be encrypted. \\ | |
| - | //Leave of Absence// | + | (G) Proper Handling of Mechanical Components. Training on the proper use and handling of CPUs, Servers, flash drives, external hard drives shall be given to the user of electronic systems. (addressable)\\ |
| - | * User IDs of employees/staff who are on extended leave of absence shall be disabled until they return for work.\\ | + | (H) Back-up components such as servers, flashdrives, external hard drives shall be stored away from possible electromagnetic interference. (addressable)\\ |

| - | + | (J) Interface Integration of Information Systems. Data transmission from electronic medical records shall follow a standard for integration and interfacing to facilitate interoperability and data compatibility. (addressable)\\ | |
| - | **DATA PROTECTION**\\ | + | |
| - | * Data on many computer devices can be damaged by being moved, knocked or even when turned off. If there is a hard disk, the heads on the drive should be "parked" before moving the system to avoid destroying stored information (devices with solid state drives have a different system and are less vulnerable to movement).\\ | + | |
| - | * Due to the different variations of computers and types of connections, it is important to seize all the different cables and chargers for the seized equipment.\\ | + | |
| - | * Antivirus software must be loaded in every computer possible. The software needs to be configured regularly and automatically download updates for the latest threats. \\ | + | |
| - | * Complete back-ups of the system shall be done periodically- once a month or every few months.\\ | + | |
| - | * Back-up data tapes shall not be stored near a computer monitor or uninterruptible power supply-the electromagnetic interference coming from these devices can corrupt data on them or completely delete them.\\ | + | |
| - | + | ||
| - | **CONFIGURATION MANAGEMENT** | + | |
| - | * It is important to document how the computer system is organized to know when and how to disconnect additional pieces of equipment such as telephone modems, auto-dialers, and printers from the system. Otherwise, important information can be lost.\\ | + | |
| - | * There shall be a regular monitoring and maintenance of database and networks of health facilities to be conducted by the Database and Network administrator of the PHIE group.\\ | + | |
| + | **D. Transmission Security**\\ | ||
| + | Technical security measures to guard against unauthorized access to electronic health information that is being transmitted over an electronic communications network shall be implemented.\\ | ||
| - | **POINTS TO CONSIDER**\\ | + | **E. Identity Authentication**\\ |
| - | * The minimum server configuration shall be specified.\\ | + | Procedures to verify that a person or entity seeking access to electronic health information is the one claimed shall be implemented. Rule III (Access of Health Information) provides guidelines on authentication of access. \\ |
| - | * Provide detailed and specific protocols on encryption (e.g. encryption of data at rest).\\ | + | |
| - | (//Specific technical requirements should ideally be developed by DOST-ICTO.//)\\ | + | |
| - | * Security features shall be incorporated in the system requirements.\\ | + | |
| - | * HIS should only be for recording and record keeping, but access to the medical records should be under the MRS.\\ | + | |
| + | **F. Storage Security**\\ | ||
| + | Implementation Specifications:\\ | ||
| + | (A) Data stored in portable data storage devices (e.g. USB drive, portable hard drives, etc.) must be encrypted. | ||
| + | (B) Data stored in cloud storage services (e.g. Dropbox, OneDrive, Google Drive, etc.) must be encrypted. | ||
