Cloud computing services have the characteristics of high cost performance, high flexibility, dynamic scalability and professional security service guarantee, which effectively help to improve management efficiency, save costs and enhance comprehensive security protection capabilities. At the same time, cloud computing services are also facing many challenges, such as the security of the basic platform of cloud computing technology, the security management of cloud data, the lack of cloud computing service security professionals and other security risk issues, leading to an endless stream of cloud platform data security incidents.
As an emerging technology with rapid iteration, cloud computing technology still has insufficient security considerations in the design, application, testing and deployment of cloud platforms. In the operating environment with highly concentrated resources, cloud platforms are easy to become the target of hackers. Compared with the network environment of traditional enterprises, cloud platforms face greater attack threats and have greater impact.
Basic platform risk
Compared with traditional IT infrastructure, the system structure of cloud computing infrastructure is more complex, with large equipment scale and many application types, which brings greater challenges to the security management of cloud computing infrastructure platform. From the security inspection and security drill over the years, there are still a large number of high and medium risk security vulnerabilities such as operating system vulnerabilities, configuration errors, policy failures and so on in the core software and hardware devices of some cloud computing basic platforms; Security vulnerabilities such as information disclosure, unauthorized access, and cross site scripting are often exposed in various cloud management platforms and business operation support systems; The cloud platform remote operation and maintenance mode and identity authentication mechanism have exposed serious risks in the project implementation; Virtual machine jump attacks, side channel attacks and other cases occur from time to time between different tenants sharing physical infrastructure due to the failure of separating storage, memory, routing and other mechanisms; After stealing user credentials through phishing, cloud computing service tracking and local attacks are carried out, resulting in an increasing number of cases of data leakage; The imperfect key management mechanism of cloud computing service and the lack of guarantee for the compliance, correctness and effectiveness of cryptographic technology have always been the security concerns of cloud computing service infrastructure platforms stylishster .
Data security risks
Data security is one of the ultimate goals of cloud computing service security. At the same time, data security risk is also the primary consideration when users choose cloud computing service providers. However, from the current situation, there are still many hidden dangers of data security in current cloud computing services: in the process of data transmission and sharing, data is not encrypted or there are defects in the encryption mechanism, and third-party calls are transmitted in clear text, When data is communicated between different VMS on the same physical server through the internal virtual network of the server, the data security protection mechanism is not well considered, which may be exploited by attackers, resulting in data information disclosure; There are still a large number of important and sensitive data in the cloud computing infrastructure that are not protected by encryption technology, which brings opportunities to hackers and other criminals, leading to information leakage or tampering; During the migration of cloud service data, the legacy data is not completely cleared, the transmission data is not effectively protected, and the backup data is not reasonably disposed, which often leads to the risk of data leakage; The open interface management of development, testing and production environment is not strict, which leads to data leakage cases in data migration projects from time to time; In cloud computing services, problems such as excessive collection of users’ personal information, illegal use of personal information, and violation of personal information protection law also occur frequently.
Supply chain security risk
At present, although the cloud management platform software, servers, network security equipment, network switching equipment and various application software used by many cloud computing service platforms have been widely supplied by domestic manufacturers, the main suppliers of CPU, memory, hard disk and key chips used in the above devices are still mainly from overseas enterprises such as the United States and South Korea. “Chip outage event” has sounded an alarm for us, which are hidden in the secondary The security risk in the three-level supply chain will remain a real risk that cloud computing service providers need to continue to pay attention to for some time to come. In addition, the development of digital supply chain is the future trend, and supply chain security has become an important challenge for network security system.
Cloud computing is critical in enterprise backup. Today’s businesses face daily threats such as extortion software, network attacks, natural disasters, and the common occurrence of accidentally deleting files. As a result, a dependable cloud data backup procedure must be followed. Furthermore, because many cloud computing companies offer competitive pricing, online backup technology offers enterprises a simple way to comply with the 3-2-1 backup rules.
With Vinchin Backup & Recovery, you can also easily build an offsite disaster recovery (DR) center by duplicating XenServer backups at the primary site to a remote site or external storage.
