SaaS environments are rising as an “unaddressed blind spot” in enterprise cyber safety for Australian and APAC organisations, based on SaaS safety administration agency Obsidian Safety. This subject is partially attributed to confusion across the shared duty mannequin in SaaS contracts.
In September, Obsidian Safety, which introduced that it’s increasing operations throughout Australia and APAC, stated it expects a surge in native organisations re-evaluating their SaaS safety methods as soon as they full ongoing cloud safety critiques.
Andrew Latham, who has joined Obsidian from Crowdstrike as senior gross sales engineer for Asia-Pacific and Japan, instructed TechRepublic that native organisations ought to transfer past paper checklists when assessing SaaS vendor safety. He additionally famous many purchasers nonetheless misunderstand the SaaS shared duty mannequin.
SaaS software program estates turning into ‘frontline for cyber threats’
SaaS assaults are rising in frequency, Obsidian famous, and the results are rising extra extreme. This 12 months’s breach at Ticketek, an Australian occasion ticketing firm, noticed the information of 17 million individuals turn out to be uncovered after a risk actor gained entry to a third-party supplier.
“The implicit belief many organisations have in SaaS suppliers to configure functions for them usually leaves delicate information unknowingly uncovered,” Chisholm stated. “Unawareness of the shared duty mannequin can go away SaaS functions unsecured, posing an enormous threat to companies’ and people’ information.”

Latham stated SaaS vendor threat in Australia and APAC is similar to different world markets.
“SaaS platforms are ubiquitous, with easy accessibility from anybody or something related to the Web,” he defined. “What we’re seeing globally is a shift away from advanced assaults the place endpoints are focused to entry and exfiltrate information, in the direction of easier assaults aimed toward account takeover and information saved in SaaS Techniques.”
Obsidian discovered that extra business-critical data is migrating to SaaS. Whereas the variety of SaaS functions in use varies broadly, Productiv analysis estimated that corporations with fewer than 500 workers use a mean of 253 apps — rising to 473 apps for corporations with over 10,000 workers.
Organisations usually misunderstand their function within the SaaS vendor shared duty mannequin for safety.
Sometimes, SaaS distributors and clients collaborate to make sure sturdy information safety. For instance, distributors could also be liable for underlying infrastructure safety, reminiscent of information facilities, whereas clients might primarily handle elements like consumer entry administration or software configuration.
“Most organisations are within the strategy of securing their Infrastructure-as-a-Service real-estate as they transfer extra workloads to the cloud,” Latham stated. “What most don’t realise is that there’s a Shared Safety Mannequin that each one cloud suppliers, together with SaaS, implement.”
He added: “With IaaS, you possibly can implement your individual controls. Nevertheless, with SaaS you can not. There’s a broad assumption the SaaS supplier is caring for the safety of the client information, however they usually aren’t.”
Paper-based questionnaires not sufficient to evaluate SaaS vendor threat
Paper-based questionnaires are sometimes used throughout procurement to confirm SaaS distributors meet safety necessities. Latham stated these questionnaires might not present deep sufficient perception into how a SaaS supplier manages safety and protects in opposition to dangers to information, reminiscent of account takeovers.

“The most important subject can be to grasp {that a} paper-based questionnaire just isn’t sufficient when assessing a brand new SaaS supplier,” Latham stated. “Many latest high-profile breaches have been account takeovers. These sorts of assaults, in relation to the Shared Accountability Matrix, are above the road the place the SaaS vendor takes duty.”
SaaS provide chain threat like ‘darkish facet of the moon’
Prolonged third- and fourth-party software program provide chain threat is widespread within the SaaS market.
Although organisations assess major SaaS suppliers, these distributors usually combine with a number of SaaS distributors themselves in an advanced SaaS mesh, making it tough to evaluate actual dangers to information.
“It’s analogous to the darkish facet of the moon,” Latham stated. “There’s as much as 10 occasions as a lot information switch occurring between third- and fourth-party SaaS techniques than there’s seen on the ‘entrance door.’
“Whereas the provision chain would possibly recommend a SaaS supplier is a recognized provider of companies required to help the enterprise, it’s all of the unsanctioned integrations which might be a problem,” he added.
These integrations can seem “harmless on the floor,” however when exploited can permit adversaries to exfiltrate SaaS information unbeknownst to the SaaS tenant.
“There are numerous examples the place trusted integrations with third- and fourth-party SaaS distributors are abused, exposing information to unauthorised customers,” Latham defined.
Obsidian Safety expects deal with SaaS after cloud
Australian corporations will be grateful that, not like in another elements of the world, the market has been largely freed from SIM Swap assaults. These assaults happen when cyber criminals trick telecommunications corporations into altering a sufferer’s cellular service to a SIM card that they management.
“ACMA’s [The Australian Communications and Media Authority] necessities for identification checks for telecommunications suppliers has all however eradicated SIM swapping assaults, that are nonetheless prevalent in different areas,” stated Latham.
Nevertheless, the issue of SaaS safety stays, although Obsidian believes it would quickly turn out to be a spotlight.
“Usually, we see many Australian organisations have in-flight initiatives for IaaS workloads. As soon as accomplished, they’ll then take a look at SaaS. Different markets, just like the US, are most likely 18 months forward, having completed their preliminary IaaS safety initiatives and kicked off SaaS safety initiatives,” Latham stated.
