The Shared Responsibility Model: What Startups Need to Know About Cloud Security in 2025
After transferring to the cloud, many startups normally really feel all the load is lifted, and they’re lastly free from {hardware} complications. They assume main cloud suppliers like Azure, AWS, or Google Cloud maintain each side of cloud safety.
These suppliers shield issues beneath, however you might be nonetheless chargeable for the security of your information, settings, and entry guidelines. This is the place shared accountability comes in. Not understanding how this works accurately can imply hassle, like exposing your working system, functions, and information to cyber attackers.
To provide help to keep away from these failures, in this text, I’ll break down how shared accountability works and the mandatory actions you and your staff want to take to safe your cloud surroundings. If you might be already leveraging cloud computing or heading there, that is for you.
What is the Shared Responsibility Model all about?
Shared accountability is the collaborative effort between cloud suppliers and their clients. This mannequin specifies the obligations of each events in retaining the cloud surroundings secure. The cloud supplier is chargeable for safeguarding the cloud infrastructure, whereas clients are chargeable for securing what’s contained in the cloud, together with functions, configurations, and information.
How Shared Responsibility Varies Across IaaS, PaaS, and SaaS
From a common perspective, the concept behind the shared accountability mannequin is kind of straightforward to perceive: you, the cloud buyer, safeguard sources you possibly can management in the cloud, whereas the cloud service suppliers (CSPs) take care of the remainder. However, this strategy can differ relying on the cloud service class (IaaS, PaaS, and SaaS) concerned. Let’s get proper into it and uncover how they’re completely different.
Infrastructure as a Service (IaaS): You are primarily chargeable for safety right here. The supplier offers you the mandatory instruments (server, storage), however the way you configure your setup and safe your information and app is completely up to you.
Platform as a Service (PaaS): In PaaS, the cloud suppliers do extra work. They safe the infrastructure and platform when you hold your app secure and determine who can use it.
Software as a Service (SaaS): Here, virtually every little thing, down to the software program itself, is dealt with by the CSPs. The solely factor you want to do is to management who has entry to what and guarantee customers have the right permissions.
What occurs whenever you misunderstand shared accountability?
Misunderstanding the shared accountability mannequin may result in errors that may jeopardize the safety of your cloud surroundings and enterprise. Your staff could make varied errors when they do not know their obligations. Here are frequent errors:
- Leaving S3 Buckets Public: Some startups mistakenly publicise their cloud storage (like Amazon S3). As a end result, anybody on the web can see their delicate information, similar to buyer data and firm secrets and techniques. Although exposing S3 buckets could be a easy mistake, it causes huge safety breaches. It is essential to limit entry to solely approved people.
- Using Default Passwords or Admin Access for All Users: Many startups make the error of not altering default passwords or giving all their customers admin entry to the cloud system. This is completely unsafe. Default passwords are a hacker’s dream as a result of they’re very straightforward to guess, leaving open doorways for breaches. Also, giving entry to many customers can create vulnerabilities.
- Ignoring Configuration Responsibilities: Sometimes, startups assume their suppliers have secured each side of their cloud safety and that each one safety is in place. However, this isn’t the case. You should nonetheless configure your firewalls, id entry, and encryption settings to safe your cloud surroundings.
Real penalties brought on by these frequent errors:
- An exemplary case is the Capital One breach in 2019. A misconfigured firewall working on Amazon Web Services allowed hackers to steal delicate data. This theft put the private information of greater than 100 million clients in danger, proving how a small error in safety configuration may result in a important state of affairs.
- Another key instance is the Verkada breach in 2021. Hackers managed to achieve management of a safety system that was supposed to be protected by a ‘tremendous Admin’ account, which had its username and password publicly obtainable. This account supplied hackers entry to Verkada’s AWS-hosted digicam techniques. They gained management of over 150,000 safety cameras in extraordinarily delicate areas, together with hospitals, prisons, Cloudflare workplaces, and Tesla factories. They exploited their privileged entry to view dwell and archived footage of personal areas and launched some clips.
The influence of those errors could be extreme. Startups could face:
- Data Leaks: Sensitive buyer or enterprise data is made public.
- Lawsuits: Companies could face lawsuits by shoppers or companions if their information is breached.
- Fines from Regulators: If you break the regulation on information safety, you have got to face penalties from regulators like GDPR and CCPA, which can end result in paying fines.
- Loss of Trust: Regaining the belief of consumers shall be troublesome as soon as they lose confidence in your organization’s potential to hold their information secure
What Startups Are Responsible For

What Cloud Providers Are Responsible For
When you utilize a cloud service, similar to Amazon Web Services (AWS) or Google Cloud, the supplier has important responsibilities- however just for sure elements. In easy phrases, here’s what they handle:
1. Physical safety: Providers hold the server working easily and safe information facilities with subtle measures like biometric entry, retaining the ability on, and 24/7 monitoring. Protecting it from catastrophe or break-ins.
2. Network infrastructure: They oversee the {hardware} (servers and storage) and the software program that retains the infrastructure working easily.
3. Host OS and hypervisor: Cloud suppliers handle the working system and the hypervisor. A hypervisor, also referred to as the Virtual Machine Monitor (VMM), allows a number of digital machines to run on a single bodily server.
4. Managed providers are safe (to an extent): If you utilize a managed database like Amazon RDS, the supplier secures the database. However, they do not handle your login data; the way you shield your passwords and credentials is up to you.
Here’s the important level you want to bear in mind: “Security of the cloud” is the accountability of the supplier; they safe their techniques. “Security in the cloud” is up to you; you have received to safe what you have got inside their system.
