Want to ensure software security at low cost? Five safety tasks worth considering

It is not enough to just scan the security vulnerabilities of an application after it goes online . The safe left shift method should be DevOps Start when the team starts developing applications and configuring infrastructure , This allows vulnerabilities to be resolved before they become more widespread and costly to fix . This is it. DevSecOps Core principles of .

Move left safely , Enterprises can identify misconfigurations and other security risks before users are affected . Cloud computing is being implemented DevOps Has played a great role , Therefore, protecting the cloud environment and workload can defend CI/CD Safety of assembly line , Ultimately protect the safety of customers .

Here are DevOps What the team should consider when moving to the left safely 5 An important safety task ：

1、 Work with the security team . Safe left shift is a major change . In addition to setting up reasonable processes and using appropriate tools , Enterprises must rethink the way they operate , stay CI/CD Introduce software testing process earlier in the pipeline 、 Tools and related expertise .DevSecOps It's not simply putting security responsibility on developers , It's about changing roles and expectations , And use appropriate tools , Achieve a balance between security and development . Security should have a high priority from the beginning of the development cycle , Not in SDLC Only later did we begin to pay attention to .

2、 Realize frequent automated testing . Safe left shift requires early and frequent testing , Through automated code testing , Developers will be reminded of security problems when working , In this way, they can correct problems before the software enters the production environment . Automated tools for scanning vulnerabilities can reduce the chance of human errors that may occur in manual testing , And expand the coverage , To check more software . Code is scanned at every stage of the development process , Therefore to SDLC There will not be a large backlog of code to be reviewed in the later stage .

The strategy of safely moving to the left requires the integration of one or more tools into CI/CD Pipeline to find known vulnerabilities and identify other security issues . The types of tools commonly used include static application security testing （SAST）、 Dynamic application security testing （DAST）、 Interactive application security testing （IAST）, Key detection and software component analysis （SCA）. Of course , Before deciding which new tools to introduce into your process , You should first evaluate your existing tools .

3、 Conduct penetration tests in the process . Although automated testing is DevSecOps The prerequisites for , But automation alone may still have potential problems that cannot be found . Manual security assessments such as penetration testing can check the security of applications by simulating network attacks . Such additional testing can minimize security risks and may catch problems that automated testing cannot detect .

Before entering the production environment , Ask a security engineer to help you review the software and conduct penetration testing to ensure that all potential problems have been mitigated . Instead of knowing the existence of vulnerabilities after being exploited by attackers , It's better to directly cover all the basic code and conduct additional tests .

4、 Make sure your software is up to date . Always use the latest version of software is the core of network security . Developers must ensure that the software they use （ operating system 、 Application framework and third-party libraries ） Keep it up to date , This means that the security patch is also up to date . Whether it's software from suppliers or the open source community , Downloading software updates is an important step to protect software security .

5、 Look for opportunities for safety training . Developers are not security experts , But they play a key role in the production of secure applications , Therefore, developers should also understand the basic knowledge of secure coding and testing . With the increasing demand for software , Developers should consider security training according to their specific roles and needs . Appropriate training and support can provide you with the background information you need , To produce practical and safe code .

Talking about software security , There is no panacea that can completely ensure that your code is always safe . By adopting these practices , You can find more vulnerabilities and patch the code before it is deployed .
