Due to its very specific nature, the serverless paradigm stands out in several aspects when it comes to security:
Cloud providers manage the operating system, runtime security, and patching. This is a guarantee, given the scale of today's providers;
The ephemeral, stateless nature of serverless computing makes life harder for attackers. The fact that serverless functions come and go, without memory, reduces the risk of long-term attacks ;
The small size of the code blocks makes them easy to analyze by CSP security tools.
On the other hand, this architecture also creates vulnerabilities . Every function becomes a potential point of attack , making it harder for vendors to monitor their servers. It is also more complicated for both the CSP and the coder to observe multiple processes and multiple entry/exit points.
Traditional applications have a clearer australia whatsapp shopping data perimeter, with the outside and inside clearly differentiated. Traditional security elements such as WAF, firewalls and IDS can be installed.
Finally, it should be noted that cloud-native applications can use numerous modules and libraries with code from various third-party sources. Potential attackers could then try to include malicious code in common projects.

Serverless: An Architecture to Adopt Urgently?
As is often the case with emerging technologies and concepts, we need to take a step back before deciding whether to embrace or reject them . They only make sense in a certain context.
Beyond the mere technical aspect, their use can also impact your organization's human resources . It requires you to have a strong team of coders , which you may need to reinforce.
At the same time, it may mean a reduction in the resources dedicated to infrastructure and its management.
