According to The State of Cloud Security 2020[1], a global survey from Sophos, six in ten (60%) organisations from South Africa experienced a public cloud security incident in the last year – including ransomware (25%), other malware (28%), exposed data (28%), compromised accounts (27%), and cryptojacking (26%). Globally, organisations running multi-cloud environments are greater than 50% more likely to suffer a cloud security incident than those running a single cloud.
Europeans suffered the lowest percentage of security incidents in the cloud, an indicator that compliance with General Data Protection Regulation (GDPR) guidelines are helping to protect organisations from being compromised. India, on the other hand, fared the worst, with 93% of organisations being hit by an attack in the last year.
“Ransomware, not surprisingly, is one of the most widely reported cybercrimes in the public cloud. The most successful ransomware attacks include data in the public cloud, according to the State of Ransomware 2020 report, and attackers are shifting their methods to target cloud environments that cripple necessary infrastructure and increase the likelihood of payment,” said Chester Wisniewski, principal research scientist, Sophos. “The recent increase in remote working provides extra motivation to disable cloud infrastructure that is being relied on more than ever, so it’s worrisome that many organisations still don’t understand their responsibility in securing cloud data and workloads. Cloud security is a shared responsibility, and organisations need to carefully manage and monitor cloud environments in order to stay one step ahead of determined attackers.”
The unintentional open door: how attackers break in
Accidental exposure continues to plague organisations, with misconfigurations exploited in 39% of reported attacks in South Africa. Detailed in the SophosLabs 2020 Threat Report[2], misconfigurations drive the majority of incidents and are all too common given cloud management complexities.
Additionally, 59% of South African organisations report that cybercriminals gained access through stolen cloud provider account credentials. Despite this, only more than a quarter (28%) of organisations say managing access to cloud accounts is a top area of concern. Data from Sophos Cloud Optix, a cloud security posture management tool, further reveals that globally 91% of accounts have over-privileged identity and access management roles, and 98% have multi-factor authentication disabled on their cloud provider accounts.
The silver lining
Nearly all respondents (89%) from South Africa admit to concern about their current level of cloud security, an encouraging sign that it’s top of mind and important. Appropriately, “Identifying sudden increase in cloud spends” tops the list of security concerns for more than three in ten (31%) of the organisations followed by “ identifying and responding to security incidents” and “convincing senior management to invest in cloud security” (30% and 30% respectively).
