In recent years, cloud computing has grown rapidly. It has completely revolutionized the business world, enabling organizations to keep up with today’s increasingly digitized landscape.
According to Grand View Research, the size of the global cloud computing market was worth $274.79 billion in 2020 and is planned for grow at a CAGR of 19.1% from 2021 to 2028.
Organizations around the world use cloud services for cloud-native development, data analysis, machine learning, and application migration, among other things. While storing and managing data has never been easier, cloud vulnerabilities have become a huge threat to data security.
According to an article from HelpNetSecurity, 93% of companies have serious concerns about public cloud security.
the VAPT youKratikal team, a CERT-In-empaned security auditor, has conducted cloud security assessments for numerous organizations around the world. Here is a list of the top 7 critical cloud vulnerabilities we found.
#1 Lack of multi-factor authentication for privileged users
One of the most common cloud vulnerabilities is the lack of multi-factor authentication (MFA) for users who are assigned to controlling privileged administrative roles. For any type of cloud environment, privileged user access should be as secure as possible. Neglecting to enable a security measure as basic as MFA can have serious consequences for an organization.
Without multi-factor authentication, it is very easy for malicious actors to compromise privileged accounts. The lack of MFA also makes these accounts vulnerable to brute force attacks. As these accounts often have elevated administrator permissions, they can be used by hackers to completely disrupt an organization’s operations and steal its data.
#2 No multi-factor authentication to join devices
In many cases, cloud environments lack multi-factor authentication (MFA) when new devices are added. This can turn out to be a huge threat to cloud security. Enabling MFA to join devices prevents malicious devices from being registered by compromised user accounts. MFA works by requiring at least two of the verification methods mentioned below:
- A password or PIN
- A trusted device that cannot be easily duplicated, such as a phone
- Biometrics like a fingerprint
When you enable MFA, users must provide at least two forms of credentials to add a device, ensuring that only legitimate users are allowed to do so.
#3 Open the S3 Bucket
According to an article by Soc Investigation, S3 bucket misconfigurations cause 16% of all cloud security breaches. Stand up for one simple storage service, S3 is AWS’s cloud storage service.
It lets you store, access, retrieve and back up as much data as you want, anytime, anywhere. According to research, approximately 1 in 6 of the 12,328 buckets identified were freely available to anyone interested.
Without proper protection, any information stored in an open S3 bucket can be easily browsed by various scripts and other tools. Open S3 buckets can cause serious data breaches and expose highly sensitive data.
In 2018, an incorrectly configured S3 bucket caused the 48 million records leaked accumulated by a private data analysis company!
#4 Incomplete deletion of data
Deleting data is something that should be done with great care. Data deletion threats typically exist because you don’t have complete visibility into where your data is physically stored in the cloud. This reduces your ability to verify whether your data has been securely deleted or not.
The risk is of particular concern in a multi-tenant cloud environment, where your data is spread across a range of different storage devices within the cloud infrastructure.
Additionally, each cloud service provider has its own data deletion procedures. In such cases, it can become difficult for organizations to ensure that their leftover data does not fall into the wrong hands. This can pose huge data security and privacy risks, putting the integrity and security of your valuable data at risk.
#5 Lambda Command Injection
The Lambda function, an AWS serverless computing service, executes code as needed. Once the code is executed, the computing instance responsible for the execution is decommissioned. Although serverless computing is significantly more secure, there are still security threats.
In the case of serverless computing services like Lambda, OS command injection falls under the category of data event injections.. Lambda command injection passes an unexpected event in the form of a request with special strings to the vulnerable function which is evaluated and interpreted for operations at the operating system level. Your data is at serious risk if your cloud service remains vulnerable to Lambda Command Injection.
#6 Insecure APIs
Application user interfaces (APIs) are widely used to streamline cloud computing. APIs not only improve convenience and efficiency, but also make it easier to share information between multiple applications. However, when unsecured, they can be a source of many vulnerabilities in the cloud and serve as a very easy point of attack for malicious actors.
By leveraging insecure APIs, hackers can easily launch DDoS attacks and gain access to sensitive company data while remaining undetected. In fact, according to a study conducted by Gartner, API abuse is expected become the most used attack vector by 2022.
#7 Failed separation between multiple tenants
The inability to maintain an infallible separation between tenants in a cloud environment that supports multitenancy can prove to be one of the cloud’s most serious vulnerabilities. Malicious actors can easily take advantage of this failure to access an organization’s assets or data through another user’s resource.
Multitenancy, when mismanaged, can increase the attack surface and lead to data leaks if its separation checks fail. This vulnerability, if not mitigated immediately, can seriously compromise the security and privacy of an organization’s data.
These are just a few of the many vulnerabilities that haunt cloud environments around the world. While moving to the cloud has become important for surviving in today’s digitalized world, failure to take the necessary precautions is nothing short of reckless endangerment.
One of the best ways to stay ahead of this threat is to regular driving cloud penetration test and mitigate all detected vulnerabilities on a priority basis. It’s always a good idea to identify any weaknesses in your cloud environment before hackers can exploit them.
