What is cloud operation and maintenance
Operation and maintenance is a very broad definition, with different responsibilities and positions at different stages for different users. In start-up companies, the work of operation and maintenance engineers may start from applying for a domain name, purchasing or renting servers, installing, adjusting the settings of network equipment, deploying the operating system and runtime environment, deploying code, designing and deploying monitoring, preventing vulnerabilities and attacks, and so on.
Trend of new operation and maintenance
With the development of the times and the popularity of the Internet, 'operation and maintenance' is also gradually developing towards a more professional direction, and the skill requirements for operation and maintenance personnel are also becoming higher and higher in the hiring process.
Now, with the acceleration of traditional enterprise digital transformation, IT systems are becoming more complex, and operation and maintenance challenges are greater. In addition to the birth and large-scale popularization of cloud computing services in recent years, the main objects of user operation and maintenance have shifted from hardware (servers, etc.) to service API-based operation and maintenance, including host operation and maintenance and application operation and maintenance.
As a core technical department, the position of operation and maintenance personnel is very important, but it is also prone to problems. Users are most concerned about the following aspects of operation and maintenance personnel: improving efficiency, operation and maintenance security, and cost reduction. Today, in the era of cloud computing, their pursuit will not change.
Improving efficiency and reducing costs go without saying, and security should be ensured before carrying out all operations. Security has many dimensions, from the well-known vulnerability protection, network defense and attack, to the commonly used code checking, permission management, log audit in enterprises, all the way to the higher-level trustworthy computing, full-link encryption, and so on. These can be collectively referred to as operation and maintenance security audit.
Three, operation and maintenance security audit system - bastion host
The bastion host, in a specific network environment, uses technical means to monitor and record the operations of operation and maintenance personnel on network servers, network devices, security devices, databases, and other equipment to ensure that the network and data are not attacked or destroyed by external and internal users.
In a word, the bastion host is used to control who can log in to which assets (preventive and in-process control), as well as to record what actions were taken after logging into the assets (post-event traceability).
Four, characteristics of cloud operation and maintenance
With the development of cloud computing technology, more and more users are beginning to migrate their business to the cloud. However, this also brings new security risks and challenges.
1. Compared with traditional operation and maintenance, cloud operation and maintenance pays more attention to security. This is because the access port of the cloud environment is facing the entire network compared to traditional IDC, which causes the uncontrollability of the access party. To enhance the security of cloud assets, in addition to the security configuration of the cloud environment itself, the attack surface during the operation and maintenance process also needs to be reduced.
2. The assets connected in cloud operation and maintenance include both cloud and on-premises, and in the cloud environment, multiple cloud platforms need to be connected, and operation and maintenance actions need to be done for multi-cloud asset management.
3. Cloud operation and maintenance often needs to deal with multi-tenant operation and maintenance environments, which requires operation and maintenance personnel to meet the minimum authorization mechanism, isolate users of multiple tenants from the software level, and avoid the leakage of tenant information.
In complex cloud environments, how to achieve cloud operation and maintenance? Firstly, it is necessary to establish a complete cloud security system architecture, including network security, host security, data security, and other aspects. Secondly, when selecting operation and maintenance audit products, it is necessary to consider their integration capabilities with cloud platforms to better manage and monitor resources in the cloud environment.
The cloud operation and maintenance security audit system builds a comprehensive pre-event prevention, in-process monitoring, and post-event audit security management system for customers, helping users smoothly pass the security compliance review.
