RSAC insights: Introducing ‘CWPP’ and ‘CSPM,’ new frameworks to secure cloud infrastructure

By Byron V. Acohido

A greater good has come from Capital One’s public pillaging over losing credit application records for 100 million bank customers.

In pulling off that milestone hack, Paige Thompson took advantage of CapOne’s lack of focus on cloud security as the banking giant rushed headlong into leveraging Amazon Web Services. Luckily, Thompson left an easy trail for the FBI to follow and affect her arrest in August 2019.

The lone wolf hacker’s lasting legacy may be that she gave the cybersecurity industry an impetus to double down on its efforts to help enterprises get a grip on cloud security.

A slew of new cloud-security frameworks have gained traction since the Capital One hack. I recently had the chance to sit down with Kevin Simzer, chief operating officer of Trend Micro, to discuss two of them: Cloud Workload Protection Platform (CWPP) and Cloud Security Posture Management (CSPM.) For a full drill down on our conversation please give the accompanying podcast a listen. Here are the key takeaways:

Cloud migration risks

The summer of 2019 was a heady time for the financial services industry. Capital One’s valuation hit record highs at a time when its senior executives bragged on Wall Street about how the bank’s aggressive adoption of AWS-supplied infrastructure would boost both profits and security. In reality, the bank wasn’t paying close enough attention to its shared responsibility for keeping its cloud-stored assets secure.

RSAC insights: Deploying SOAR, XDR along with better threat intel stiffens network defense

By Byron V. Acohido

Much attention has been paid to the widespread failure to detect the insidious Sunburst malware that the SolarWinds hackers managed to slip deep inside the best-defended networks on the planet.

Related: The undermining of the global supply chain

But there’s also an encouraging ‘response’ lesson SolarWinds teaches us, as well.

Reacting to the disclosure of this momentous supply-chain hack, many of the breached organizations were able to deploy advanced tools and tactics to swiftly root out Sunburst and get better prepared to repel any copycat attacks. It was an opportunity to put their security orchestration and automation and response (SOAR) solutions, as well as endpoint detection and response (EDR) tools, to the test.

In that sense, SolarWinds validated the truckloads of investment that has been poured into developing and deploying SOAR and EDR innovations over the past five years. I had the chance recently to visit with Leon Ward, Vice President of Product Management, at ThreatQuotient, provider of a security operations platform with multiple use cases including serving as a threat intelligence platform (TIP). We discussed current developments that suggest SOAR and EDR will continue to improve and make a difference.

For a full drill down on our conversation, please give the accompanying podcast a listen. Here are my key takeaways:

Leveraging richer intel

It was by happenstance that analysts at FireEye, a leading supplier of intrusion detection systems, stumbled into a copy of the Sunburst Trojan ever-so-stealthily embedded in FireEye’s own copy of SolarWinds’ Orion network management software. That was on Dec. 13, 2020.

RSAC insights: ‘SASE’ disrupts networking by meshing security, connectivity at the services edge

By Byron V. Acohido

It’s accurate to say that security has been bolted onto modern business networks.

It also has become very clear that we won’t achieve the full potential of digital transformation without security somehow getting intricately woven into every layer of corporate IT systems.

We’re still a long way from achieving that, but a promising roadmap has emerged. It’s a new model for architecting enterprise IT systems, dubbed Secure Access Service Edge (SASE), a term coined by top security analysts at tech advisory firm Gartner.

I had the chance to visit with Kelly Ahuja, CEO of Versa Networks, a supplier of SASE systems. For a full drill down on our discussion on why SASE could be game changer, please give a listen to the accompanying podcast. Here are the key takeaways:

Connectivity vs. security

Corporate networks exist to connect users to applications. Traditionally this was done by setting up a datacenter at company headquarters, and having employees enter the building and access applications using company-managed equipment. Thus, local area networks, or LANs, were born.

Then along came wide area networks, or WANs, as a means to securely connect several LANs set up in geographically dispersed branch offices. Over time WANs proved to be expensive and inflexible, so they began to be replaced with software-defined wide area networks, or SD-WANs, which offered heightened data-transfer efficiencies.

However, the first-generation of SD-WAN solutions were notable for one key thing: they were solely focused on improving connectivity and did little to account for security.

RSAC insights: How the ‘CIEM’ framework is helping companies manage permissions glut

By Byron V. Acohido

A permissions glut is giving rise to an explosion of new exposures in modern business networks.

Related: Securing digital identities

Companies are adopting multi-cloud and hybrid cloud infrastructures and relying on wide-open app development like never before. In doing so, permissions to make myriad software connections are proliferating. Taken together these man-to-machine and machine-to-machine connections result in cool new digital services. But they’ve also dramatically expanded the attack surface and left it wide open to threat actors.

Now comes an emerging security discipline to help companies get a grip on all of these permissions. It’s called “cloud infrastructure entitlement management,” or CIEM, not to be confused with security information and event management, or SIEM, which is something else altogether.

Last Watchdog visited with Raj Mallempati, chief operating officer of CloudKnox Security, aSunnyvale, Calif.-based cybersecurity firm, to get a better understanding of emergent CIEM systems. For a full drill down on our discussion please give a listen to the accompanying podcast. Here are key takeaways:

The permissions glut

Managing permissions in a way that doesn’t unduly tax agility has become a Gordian Knot security challenge. To start, the raw volume of permissions continues to rise exponentially. Consider that global spending on cloud infrastructure services jumped 32 percent to nearly $40 billion in the last quarter of 2020. This reflects the rise in remote work and schooling, as well as spikes in online shopping, gaming and media streaming over the past 12 to 18 months.

RSAC insights: Sophos report dissects how improved tools, tactics stop ransomware attack

By Byron V. Acohido

A new report from Sophos dissects how hackers spent two weeks roaming far-and-wide through the modern network of a large enterprise getting into a prime position to carry out what could’ve been a devasting ransomware attack.

This detailed intelligence about a ProxyLogon-enabled attack highlights how criminal intruders are blending automation and human programming skills to great effect. However, in this case, at least, they were detected and purged before hitting paydirt, demonstrating something that doesn’t get discussed often enough.

Enterprises actually have access to plenty of robust security technology, as well as proven tactics and procedures, to detect and defuse even leading-edge, multi-layered attacks. It’s clear to me that cybersecurity technical innovation and supporting frameworks, which includes wider threat intelligence sharing, are taking hold and making a material difference, albeit incrementally.

I had a lively discussion with Dan Schiappa, Sophos’ chief product officer, about this. For a drill down, please give the accompanying podcast a listen. Here are the key takeaways:

Exploit surge

ProxyLogon refers to the critical vulnerability discovered in Microsoft Exchange mail servers early this year. Criminal hacking rings have been hammering away at this latest of a long line of zero-day flaws discovered in a globally distributed system. The pattern is all too familiar: they marshal their hacking infrastructure to take advantage of the window of time when there is a maximum number of vulnerable systems just begging to be hacked.

RSAC insights: SolarWinds hack illustrates why software builds need scrutiny — at deployment

By Byron V. Acohido

By patiently slipping past the best cybersecurity systems money can buy and evading detection for 16 months, the perpetrators of the SolarWinds hack reminded us just how much heavy lifting still needs to get done to make digital commerce as secure as it needs to be.

Obviously, one change for the better would be if software developers and security analysts paid much closer attention to the new and updated coding packages being assembled and deployed on the fly, in pursuit of digital agility.

I recently had the chance to discuss this with Tomislav Pericin, chief software architect and co-founder at software security firm ReversingLabs. We talked about how the capacity to, in essence, rapidly reverse engineer new software and software updates — without unduly hindering agility — could make a big difference.

For a full drill down, please give the accompanying podcast a listen. Here are the key takeaways:

Targeting the build

One thing I did not realize about the SolarWinds hack is precisely how the attackers fooled more than 18,000 organizations into accepting an infected update of the widely-used Orion network management tool. I had assumed that they either stole or spoofed a SolarWinds digital certificate, which they then used to authenticate the tainted update. The payload malware: Sunburst, a heavily-obfuscated backdoor.

Actually, these attackers went through a lot of effort to first gain deep access inside of SolarWinds’ network. Next, they located and took control of the build process used to compile the various pieces of coding that SolarWinds’ software developers assembled to make up its Orion software updates.

“People tend to focus on the Sunburst malware, the actual backdoor that ended up in the affected update package,” Pericin told me. “But there was another malicious component, Sunspot, which was a piece of malware specifically designed to run in the Solar Winds environment, on a build machine.

RSAC insights: CyberGRX finds a ton of value in wider sharing of third-party risk assessments

By Byron V. Acohido

The value of sharing threat intelligence is obvious. It’s much easier to blunt the attack of an enemy you can clearly see coming at you.

Related: Supply chains under siege.

But what about trusted allies who unwittingly put your company in harm’s way? Third-party exposures can lead to devastating breaches, just ask any Solar Winds first-party customer.

So could sharing intelligence about third-party suppliers help?

With RSA Conference 2021 technical sessions getting underway today, I sat down with Fred Kneip, CEO of CyberGRX, to hash over the notion that a lot of good could come from more systematic sharing of the risk profiles that large enterprises routinely compile with respect to their third-party contractors.

For a full drill down on our discussion, please give the accompanying podcast a listen. Here are the key takeaways:

The genesis of risk-profiles

It turns out there is a ton of third-party risk profiles sitting around not being put to any kind of high use. Back in the mid-1990s, big banks and insurance companies came up with something called “bespoke assessments” as the approach for assessing third party vendor risk.

This took the form of programmatic audits. In order to get the blessing of financiers and insurers, enterprises had to set up systems to get their third-party suppliers to fill out extensive risk-profile questionnaires; and this  cumbersome process had to be repeated on a periodic base for as many contractors as they could get to.

CyberGRX launched in 2016 as a clearinghouse for companies to pool and share standardized assessment data and actually analyze the results for action. The idea was to benefit both the first-party contractors and the third-party suppliers, Kneip says. Thus, the Fortune 1,000 companies who collected and consumed the security profiles of major suppliers could see and analyze that data in aggregate and thus conduct a much higher level of risk analysis.
