What Is Cloud Security

Cloud Security is the latest manifestation of information security in the network age.

Cloud Security Definition

"Cloud Security" technology is the latest manifestation of information security in the network age. It integrates emerging technologies and concepts such as parallel processing, grid computing, and unknown virus behavior judgment, and obtains the latest information of Trojan and malicious programs on the Internet through the abnormal monitoring of software behaviors in the network by a large number of meshed clients. Then push it to the server for automatic analysis and processing, and then distribute the virus and Trojan solutions to each client.

"Cloud security" is an important application of "cloud" technology that emerged after "cloud computing" and "cloud storage". It is an extension of the traditional IT security concept in the cloud computing era. It has been widely used in anti-virus software and has exerted good results. The technical competition between virus and anti-virus software has won the first opportunity for anti-virus software.

Advanced features of cloud security

Cloud security is the report of a group of probes and the sharing of professional processing results. The advantage of cloud security is that in theory, the spread of the virus can be controlled within a certain area! It is related to the number of probes, survival, and virus processing speed.

Traditional reporting is done manually, while cloud security is done automatically and quickly within a few seconds in the system. This kind of reporting is the most timely, and manual reporting cannot do this. Ideally, it takes only a few seconds from a hacking Trojan to attack a computer to the entire "Cloud Security" network with immunity and detection and killing capabilities.

Difficulties in cloud security system

To establish a "cloud security" system and make it run normally, four major problems need to be solved:

First, a large number of clients (cloud security probes) are required. Only with a large number of clients can we have the most sensitive ability to perceive malicious programs and dangerous websites appearing on the Internet. Generally speaking, the higher the product usage rate of a security manufacturer, the faster the response should be. In the end, it should be possible to realize that no matter which Internet user is poisoned or visits the malware-associated webpage, he can respond the first time.

Second, professional anti-virus technology and experience are required. The discovered malicious programs are detected and should be analyzed in the shortest possible time. This requires the security vendor to have excellent technology, otherwise it is easy to cause the accumulation of samples, which will greatly reduce the results of the rapid detection of cloud security.

Third, a large amount of capital and technical input is required. The "cloud security" system requires a huge investment in hardware such as servers and bandwidth. At the same time, security vendors are required to have corresponding top technical teams and continuous research expenditures.

Fourth, it can be an open system that allows partners to join. "Cloud Security" can be an open system, and its "probe" should be compatible with other software. Even if users use different anti-virus software, they can also enjoy the results brought by the "cloud security" system.

Cloud Security Response

  • Vulnerability scanning and penetration testing
    Vulnerability scanning and penetration testing are mandatory for all PaaS and Infrastructure as a Service (IaaS) cloud security technologies. Whether they are hosting applications in the cloud or running servers and storage infrastructure, users must assess the security status of systems exposed to the Internet.

To test the integration of APIs and applications in PaaS and IaaS environments, companies that collaborate with cloud providers should focus on data in transit. And potentially illegal access to applications and data by bypassing identity authentication or injection attacks.

  • Cloud security technology configuration management
    The most important element of cloud security technology is configuration management, which includes patch management. In the SaaS environment, configuration management is completely handled by the cloud provider. In the PaaS environment, the development and maintenance of the platform are all the responsibility of the supplier. Libraries and tools for application configuration and development may be managed by enterprise users, so the security configuration standards still belong to the scope of internal definitions. Then, these standards should be applied and monitored in the PaaS environment.
  • Security control of cloud security technology
    The cloud provider is responsible for the operation of all infrastructure, including virtualization technology, networking, and storage. It is also responsible for its related code, including management interface and API, so it is very necessary to evaluate its development practice and system development life cycle. Only IaaS customers have real control over the entire system specifications; if virtual machines are deployed based on a template provided by a vendor, these virtual machines should be carefully studied and ensured before actual use.

Cloud Security Technology Classification

Cloud security can be divided into two categories in nature, one is user data privacy protection, and the other is security for traditional Internet and hardware devices.

In terms of cloud security technology, the first is the security issues brought about by multi-tenancy. Different users are isolated from each other to avoid mutual influence. In the cloud era, some technologies need to be used to prevent users from intentionally or unconsciously "going in".

Secondly, the security risks caused by the use of third-party platforms. Not all vendors that provide cloud services have their own data centers. Once a third-party cloud platform is rented, there is a problem with the authority of service provider managers.

The Best DDoS Protection Tool: Anti-DDoS of Alibaba Cloud

A distributed denial of service (DDoS) attack uses multiple computers to launch coordinated attacks against one or more targets through malicious programs. The attack undermines the performance or consumes network bandwidth and makes the target servers unresponsive.

Typically, an attacker installs a DDoS master program on a single computer using an unauthorized account and then installs agent programs on multiple computers. During a specified period, the DDoS master program communicates with a large number of agent programs. When the agents receive the command, they initiate attacks. The master program can initiate hundreds or even thousands of agent programs within seconds.

Redefining Security in 2021

2021 has started with a sudden change in how IT and computing work. Remote work culture and business assessments based on the changing trends have enabled another paradigm shift in computing. The evolution of cloud computing standards and security associated with the entirety of this evolution is sending ripples in every direction.

I have said it before, and I will say it again; when security systems evolve, the threats evolve too. Alibaba Cloud has made remarkable developments when it comes to providing end-to-end security solutions to enterprises, online businesses, websites, and everything on the cloud. Alibaba Cloud provides security assurance and manages the infrastructure to ensure an unhinged delivery process.

Alibaba Cloud has worked tirelessly to develop cloud-native security services that showcase an adaptive architecture. By default, these services provide extensive monitoring and metrics collection capabilities to ensure real-time and continuous threat assessment for a better security structure.
