Cybersecurity Classified Protection, which requires control and management through security technologies. In level protection work, what areas should we pay attention to?
1. "As long as nothing goes wrong, we don't need to do protection."
Cybersecurity Classified Protection is an important measure to ensure network security. It is a legal obligation to protect networks from interference, destruction, unauthorized access, data leakage, theft, and tampering. Neglecting Cybersecurity Classified Protection means not fulfilling legal obligations, and there have been real cases of penalties for non-compliance. Therefore, Cybersecurity Classified Protection should be taken seriously and conducted in a timely manner.
2. "Internal networks and systems that are not exposed to the internet don't need Cybersecurity Classified Protection."
From a technical perspective, internal networks are not inherently secure, and they often have some form of connection, direct or indirect, to the internet. From a legal standpoint, all non-classified systems fall within the scope of Cybersecurity Classified Protection, regardless of whether they are on internal or external networks. Internal systems often have inadequate security measures, and they can be compromised or vulnerable to risks. Thus, Cybersecurity Classified Protection should be implemented regardless of the network environment.
3. "Systems hosted on the cloud don't need Cybersecurity Classified Protection."
According to the principle of "who operates, who is responsible; who uses, who is responsible; who supervises, who is responsible," the responsibility for the system still lies with the network operator, even if it is hosted on the cloud. The system should be classified and undergo Cybersecurity Classified Protection accordingly. Cloud hosting does not transfer the responsibility; it only changes the physical location of the system. While the security responsibilities may differ depending on the cloud service model (IaaS, PaaS, SaaS), they are not completely eliminated.
4. "Cybersecurity Classified Protection is just about conducting an evaluation."
Cybersecurity Classified Protection work involves five key components: classification, record-keeping, evaluation, construction and rectification, and supervision and review. Evaluation is just one part of the process, serving as a starting point to identify gaps and analyze risks in the current system. It is essential to address vulnerabilities, strengthen security measures, and improve the overall security posture of the information system to reduce the probability of attacks.
5. "Lower system classification is better."
The final classification of a system is determined based on the degree of harm and impact on the entity. It should be based on objective criteria rather than subjective preferences. While lower classification requirements may seem easier to meet, they often come with less stringent security measures. In the event of an attack, the consequences could be greater, resulting in more significant losses.
6. "One unit only needs to conduct a single Cybersecurity Classified Protection."
Cybersecurity Classified Protection is conducted on information systems as a whole, rather than on individual units. An information system includes physical infrastructure, servers, hosts, applications, databases, network devices, and security equipment. The evaluation encompasses these tangible components as well as the corresponding security management system.
7. "Cybersecurity Classified Protection only needs to be done once."
Cybersecurity Classified Protection work is an ongoing process, and evaluations are conducted periodically. Systems at Level 3 and above require annual evaluations, while Level 2 systems in certain industries may have a biennial evaluation requirement. For industries without specific requirements, it is generally recommended to conduct evaluations every two years.
8. "Cybersecurity Classified Protection requires expensive remediation."
The cost of remediation depends on factors such as the system's classification, the existing security measures, and the network operator's expectations for evaluation scores. It is not necessarily expensive. Remediation typically involves improving security policies, implementing security services and measures, and acquiring security equipment. Network operators can take significant steps in improving security on their own or by engaging service providers.
9. "Where should the system classification and record-keeping for cloud systems be conducted?"
Cloud systems are deployed on various cloud platforms, and the physical addresses of these platforms are often different from the network operators of the cloud systems. Moreover, large cloud platforms may have multiple physical nodes, making it difficult to determine their specific physical locations. Therefore, for the convenience of local public security supervision, the system classification and record-keeping for cloud systems should be conducted at the location where the actual operational team of the system is located, specifically at the local network security department.
