SURVEILLANCE OF INFORMATION SYSTEM SECURITY

Article 3. Surveillance principles

1. Surveillance is carried out regularly and continuously.

2. Surveillance, analysis and prevention methods are actively implemented to promptly detect and prevent cyber information security incidents and risks.

3. The stability and security of information provided or exchanged during the surveillance are ensured.

b) Consolidation, synchronization, verification and processing of information on cyber information security to detect cyber information security intrusions, risk and incidents or remove inaccurate information.

3. Indirect surveillance is surveillance carried out through techniques for collecting information from relevant information sources; inspecting and surveillance of entities under surveillance for determine their operation and capacity to satisfy and connect with other relevant factors to detect cyber information security intrusions, risks and incidents. Indirect surveillance includes the following activities:

a) Collection, analysis and verification of information about cyber information security intrusions, risks and incidents related to entities under surveillance collected from relevant information sources;

b) Remote or direct inspection and review of entities under surveillance for assessing situation and detecting cyber information security intrusions, risks and incidents able to be used, intruded or damaged.

Article 5. Requirements for direct surveillance by managers of information systems

c) Interfaces facilitating the continuous surveillance and surveillance by supervisors are provided;

d) The following input information is collected and analyzed: wed servers with web applications such as portal, online public services, etc; warnings and log files of basic monitoring equipment; warns and log files of firewalls established for protecting internet connection related to entities requiring surveillance;

e) The central surveillance is suitable for quantity and formats of and able to analyze information on cyber information security collected from information systems under surveillance.

2. Collection of information on cypherinformation security and basic monitoring shall satisfy the following requirements:

a) Information on cyber information security is collected from log files and warnings of software or equipment related to entities requiring surveillance for provision for central host computer servers or at the request of competent authorities affiliated to Ministry of Information and Communications. The following information on cyber information security is collected and provided: wed servers with web applications such as portal, online public services, etc; warnings and log files of basic monitoring equipment; warnings and log files of firewalls established for protecting internet connection related to entities requiring surveillance;

b) Basic monitoring equipment is able to detect cyber information security intrusions, risks and incidents and is established to ensure surveillance of all Internet connections of entities requiring surveillance;

c) Surveillance equipment has functions of detection and establishment of separate rules for detecting intrusions based on the following information: source IP address, destination IP address, source port address, destination port address, special data segments in transmitted packets. If organizations and individuals use basic monitoring equipment themselves, existing applications such as IDS, IPS, Web firewalls, etc are prioritized to be used basic as surveillance equipment;

d) Information systems serving the electronic government using encoded protocol (“https” for example) have technical measures for ensuring that equipment for surveillance cyber information security will have sufficient information to detect cyber information security intrusions, risks and incidents;

e) Basic monitoring equipment is established and connected with the surveillance system of the Ministry of Information and Communications according to instructions and requirement of competent authorities.

3. The surveillance includes the following activities:

a) Monitoring, continuously carrying out surveillance and making daily reports and ensuring the stable and continuous operation of and information collection of by the manager’s surveillance system;

b) Formulating and issuing regulations on cyber information security surveillance which specify time limit for regular collection of processing results and making reports;

c) Surveillance and operating the basic monitoring equipment to ensure the stability, continuity and timely adjustment in case of changes and following instructions provided by the Ministry of Information and Communications to ensure effective surveillance;

d) Making weekly reports on surveillance results and sending them to managers of information systems. A weekly report shall contain time of surveillance, the list of noticeable intruded entities (ID address, description of provided services and time of intrusion); intrusion methods that have been detected and relevant evidence; entities carrying out intrusions; changes in information systems under surveillance and surveillance systems, etc.;

dd) Classifying cyber information security risks and incidents according to specific cases;
