SaaS environments are rising as an “unaddressed blind spot” in enterprise cyber safety for Australian and APAC organisations, in line with 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 implications are rising extra extreme. This 12 months’s breach at Ticketek, an Australian occasion ticketing firm, noticed the information of 17 million individuals grow to be uncovered after a menace actor gained entry to a third-party supplier.
“The implicit belief many organisations have in SaaS suppliers to configure functions for them typically leaves delicate knowledge unknowingly uncovered,” Chisholm stated. “Unawareness of the shared duty mannequin can go away SaaS functions unsecured, posing an enormous danger to companies’ and people’ knowledge.”

Latham stated SaaS vendor danger in Australia and APAC is corresponding to different international 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 knowledge, in the direction of less complicated assaults geared toward account takeover and knowledge saved in SaaS Techniques.”
Obsidian discovered that extra business-critical info is migrating to SaaS. Whereas the variety of SaaS functions in use varies extensively, Productiv analysis estimated that corporations with fewer than 500 staff use a median of 253 apps — rising to 473 apps for corporations with over 10,000 staff.
SaaS shared duty mannequin not being assessed in-depth
Organisations typically misunderstand their function within the SaaS vendor shared duty mannequin for safety.
Sometimes, SaaS distributors and clients collaborate to make sure sturdy knowledge safety. For instance, distributors could also be chargeable for underlying infrastructure safety, reminiscent of knowledge facilities, whereas clients could primarily handle elements like consumer entry administration or software configuration.
“Most organisations are within the technique 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’ll be able to implement your personal controls. Nonetheless, with SaaS you can not. There’s a broad assumption the SaaS supplier is taking good care of the safety of the shopper knowledge, however they typically aren’t.”
Paper-based questionnaires not sufficient to evaluate SaaS vendor danger
Paper-based questionnaires are sometimes used throughout procurement to confirm SaaS distributors meet safety necessities. Latham stated these questionnaires could not present deep sufficient perception into how a SaaS supplier manages safety and protects towards dangers to knowledge, reminiscent of account takeovers.

“The most important subject can be to grasp {that a} paper-based questionnaire 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 danger like ‘darkish aspect of the moon’
Prolonged third- and fourth-party software program provide chain danger is frequent within the SaaS market.
Although organisations assess main SaaS suppliers, these distributors typically combine with a number of SaaS distributors themselves in a sophisticated SaaS mesh, making it tough to evaluate actual dangers to knowledge.
“It’s analogous to the darkish aspect of the moon,” Latham stated. “There may be as much as 10 instances as a lot knowledge switch occurring between third- and fourth-party SaaS techniques than there may be seen on the ‘entrance door.’
“Whereas the availability chain may recommend a SaaS supplier is a recognized provider of companies required to assist the enterprise, it’s all of the unsanctioned integrations which can be a problem,” he added.
These integrations can seem “harmless on the floor,” however when exploited can permit adversaries to exfiltrate SaaS knowledge unbeknownst to the SaaS tenant.
“There are various examples the place trusted integrations with third- and fourth-party SaaS distributors are abused, exposing knowledge to unauthorised customers,” Latham defined.
Obsidian Safety expects concentrate on SaaS after cloud
Australian corporations could be grateful that, in contrast to 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 id checks for telecommunications suppliers has all however eradicated SIM swapping assaults, that are nonetheless prevalent in different areas,” stated Latham.
Nonetheless, the issue of SaaS safety stays, although Obsidian believes it’ll quickly grow to be a spotlight.
“On the whole, we see many Australian organisations have in-flight tasks for IaaS workloads. As soon as accomplished, they’ll then have a look at SaaS. Different markets, just like the US, are most likely 18 months forward, having completed their preliminary IaaS safety tasks and kicked off SaaS safety tasks,” Latham stated.
