Qualys report appears at how misconfiguration points on cloud service suppliers assist attackers achieve entry.
Cloud misconfiguration — incorrect management settings utilized to each {hardware} and software program components within the cloud — are risk vectors that amplify the chance of knowledge breaches. A brand new report from cloud safety vendor Qualys, authored by Travis Smith, vice chairman of the corporate’s Risk Analysis Unit lifts the lid on threat elements for 3 main cloud service suppliers.
Concerning the report
Smith wrote that Qualys researchers, analyzing misconfiguration points at Amazon Net Providers, Microsoft Azure and Google Cloud Platform, discovered that inside Azure, 99% of the disks are both not encrypted or aren’t utilizing customer-managed keys that give customers management of encryption keys that defend knowledge in software program as a service functions.
The research, which reviewed encryption, identification and entry administration and failures to observe external-facing belongings examined dangers to unauthorized entry as a consequence of:
- The complexity of cloud environments
- Lack of awareness in maintaining with evolving applied sciences
- Insecure settings and permissions brought on by human errors
- Speedy deployment compromising safety implementation measures
- Lack of management and visibility of cloud-resident unencrypted or delicate knowledge because of the dynamic nature of cloud environments
Smith wrote that the corporate’s reachers discovered that 85% of the keys aren’t rotated, that means computerized key rotation isn’t enabled. Amazon presents computerized key rotation — producing new cryptographic materials — on a 365 day cycle for keys.
Qualys additionally reported that in GCP environments, 97.5% of digital machine disks for crucial digital machines lack encryption utilizing customer-supplied encryption keys.

Id and Entry Administration
Qualys discovered poor implementation ranges of IAM in all three main suppliers:
- Multifactor authentication: AWS isn’t enabled for 44% of IAM customers with console passwords. IAM Entry Analyzer isn’t enabled in 96% of the accounts scanned by Qualys.
- In Azure, scans for enabling authentication and configuring consumer certificates inside Azure App Service fail 97% of the time.
Publicity of external-facing belongings from leaky S3 buckets
Qualys famous {that a} widespread mistake by customers throughout the three platforms is public publicity of knowledge:
- Qualys reported 31% of S3 buckets are publicly accessible.
- The misconfiguration of leaving public community entry enabled was seen in 75% of the Azure databases.

Heart for Web Safety work presents insights to remediation
Suggestions by the agency included reviewing analysis by the Heart for Web Safety together with work Qualys participated in: mapping of particular person controls to the MITRE ATT&CK ways and strategies.
Qualys contributed to growing these CIS benchmarks for AWS, Azure and GCP. The benchmarks will assist provide some useful perception and context for defenders to higher prioritize the tons of of hardening controls accessible in cloud environments.
Qualys additionally checked out how corporations are deploying controls to harden their cloud postures throughout the three main platforms, noting that privilege escalation (96.03%), preliminary entry (84.97%) and discovery (84.97%) are passing on the highest charges.
Efforts to manage assaults early are serving to to ameliorate extra dangerous penalties additional alongside the the kill chain:
- Influence handed at solely 13.67%
- Exfiltration at solely 3.70%.
- Exploitation of public going through apps handed at solely 28.54%.
- Exploitation of distant providers, at solely 17.92%, are failing at excessive charges.
- Useful resource hijacking is passing at simply 22.83%.
Smith wrote that since crypto mining malware is a risk to cloud environments, organizations ought to think about mitigating such controls to scale back their organizational threat within the cloud.
“The lesson from these knowledge factors is that just about each group wants to higher monitor cloud configurations,” stated Smith, including that scans for CIS controls failed 34% of the time for AWS, 57% for Microsoft Azure and 60% for GCP (Determine A).
Determine A
“Even should you imagine your cloud configurations are so as, the info tells us that not frequently confirming standing is a dangerous guess. Scan the configurations usually and ensure the settings are right. It takes only one slip-up to by chance open your group’s cloud to attackers,” wrote Smith.
