Five levels of security for SaaS applications

Security risk countermeasures for SaaS applications

A secure SaaS application has five levels of security, namely physical security, network security, system security, application security, and management security. In view of the security risk problem mentioned above, a series of countermeasures and suggestions are put forward to form a complete solution.

(1) Physical security control strategy

① set up a hardware environment protection system. Service provider's system hardware and operating environment are the most basic elements of SaaS application operation, to ensure the safety of the SaaS server, communication equipment and so on to ensure the normal operation of the computer.

② to establish a multi-level backup mechanism. Data backup is to prevent system operation error or system failure to cause data loss of the protection means, can ensure that in the presence of major problems, user data can be quickly recovered and not intercepted by third parties, to ensure the security of operating service systems.

(2) Network security Control Strategy

① shoulder firewall. As the entrance and exit of information between different network or network security domain, the firewall can control the traffic flow of the network according to the security policy of the network system, and it has strong ability of resisting attack, which guarantees the security of the internal network effectively.

② Enable intrusion detection systems. This is the second security gate after the firewall, can effectively prevent hacker attacks, in the computer network real-time monitoring network transmission, analysis from the network external and internal intrusion signals. Warn the system before it is compromised, respond to the attack in real time, and provide remedial action.

③ Implement network monitoring. It is necessary to use network monitoring system to monitor the running condition of network equipment in real-time, so that the network can get the alarm in the first time of failure.

④ data Transmission Control. SaaS applications are entirely internet-based, using Secure Hypertext Protocol HTTPS (Hypertexttransferprotocoloversecuresocketlayer).

⑤ to join the network communication business. Communication operators in the network has exclusive advantages, can provide software services, server hosting, network access to the one-stop service to achieve End-to-end Sea (servicelevelagreement) protection, to reassure customers in the network stability concerns.

(3) system security Control strategy

① system reinforcement. Server security is the most intuitive embodiment of the strength of SaaS vendors in the eyes of users. Load-balancing devices can be deployed at the front end of the SaaS application server to achieve load balancing and high availability across multiple application servers.

② Vulnerability Scan repair. Whether the operating system, browser or other applications have a wide range of vulnerabilities easily exploited by hackers, to configure the Web site security scanning platform, real-time monitoring of the latest found vulnerabilities and weaknesses, and timely installation of patch fixes.

③ virus protection. Overall consideration, the development of multi-level, all-round anti-virus strategy, through the application of network anti-virus products, shut down the system of unnecessary applications and do a good job of mobile hard disk, u disk, etc. before the use of scanning anti-virus work to establish a network virus protection system.

(4) Application of security control strategy

① data isolation. In order to ensure the lowest implementation cost of the system, the software provider usually chooses the shared database and the shared data mode in the data isolation scheme, so the data isolation method must be used to ensure that the user data is still as safe as using the independent database.

② data encryption. The database for SaaS applications is managed by operators, and operators and database administrators are not entirely trustworthy. For sensitive data, such as corporate financial data, you can consider encryption.

③ permission control. Access Control List (ALC) can be used to define access rights, and to operate the data to ensure the normal use of the system by effective users.

④ identity authentication. Most small and medium-sized users do not currently have their own special identity Certification center, so the user-level control strategy certification is suitable for centralized certification, to prevent the use of illegal users system.

(5) Management security Control Strategy

① Select the appropriate SaaS service provider. The enterprise should be based on the SaaS mode business characteristics need, predetermined target set selection criteria and enterprise cost control, prudently ensure the internal selection of suppliers. Relative to price, security and service security are more important.

② Perfect Safety Management system. In accordance with the relevant requirements of computer information security, according to the principle of the combination of responsibility, right and benefit, the enterprise should establish and improve the responsibility system and security log system of SaaS system, so that it can be rule-based and legal.

③ Personnel safety Management. Improving security awareness is an important prerequisite to ensure the security of SaaS services, and should strengthen security education and technical training for system maintenance personnel and technical support personnel. The basic foothold of information security management is to standardize the behavior of employees, to enhance the safety management consciousness of operators, to cultivate the integrity and moral level of personnel, and to deal with the ability of emergency events.

④ to establish supervision system. SaaS users may not know much about the implementation process and standards of SaaS application, and can use the socialized, scientific, fair and professional supervision mechanism of third party supervision to assist implementation and management to ensure that SaaS application mode is more reasonable and effective.
