Know What’s on Your Network at All Times with Qualys Asset Inventory

Qualys has just launched a global IT asset inventory solution that offers full visibility across even the most hybrid, complex and distributed IT environments, addressing a challenge many security and IT teams face today.

When IT directors and CISOs look at their digitally transformed networks, they encounter many shadows that their legacy enterprise software tools can’t illuminate. These blind spots often include cloud workloads, containers, IoT systems, mobile devices, remote endpoints, and Operational Technology wares.

Because full visibility is essential for security, this foggy, fragmented view of a network makes the organization vulnerable to cyber attacks. Qualys Global IT Asset Inventory (AI) provides complete, continuous, structured and enriched asset inventory in hybrid environments.

“This is a really big deal because it’s the basis of security: If you don’t know what you have, you can’t secure it,” says Qualys Chief Product Officer Sumedh Thakar.

Justin Bendl, Senior Manager for Security & Compliance at Federal Home Loan Bank of Pittsburgh, says that Qualys AI has begun to assist the bank in expanding automation that provides real-time visibility into the completeness and accuracy of software assets.

“This automation is enhancing the bank’s overall control environment and further mitigating risks in a proactive manner,” Bendl says.

Philippe Courtot, Qualys Chairman and CEO, highlights the benefits of Qualys AI’s full integration with the Qualys Cloud Platform. “You will know instantly what assets connect to your network, and be able to assess their security and compliance posture in real-time, giving you unprecedented and essential visibility,” says.

Global IT Asset Inventory: The Foundation for Security and Compliance

Pablo Quiroga, Qualys’ Director of Product Management for IT Asset Management, talks about the new Asset Inventory solution

When IT directors and CISOs look at their digitally transformed networks, they encounter many shadows that their legacy enterprise software tools can’t illuminate. These blind spots often include cloud workloads, containers, IoT systems, mobile devices, remote endpoints, and Operational Technology wares.

Since full visibility is essential for security, this foggy, fragmented view of a network makes the organization vulnerable to cyber attacks. It’s a problem Qualys is tackling head on, as several speakers stated during QSC 2018 in Las Vegas.

“This is a really big deal because it’s the basis of security: If you don’t know what you have, you can’t secure it,” Qualys Chief Product Officer Sumedh Thakar said.

That’s why Qualys is releasing a global IT asset inventory solution that offers full visibility across even the most hybrid, complex and distributed IT environments. Qualys Asset Inventory, now in beta, will provide complete and detailed visibility into on premises, cloud, remote, mobile, IoT and OT assets.

“It’s the source of truth that enterprise software hasn’t been able to deliver,” Qualys CEO Philippe Courtot said. “That’s the bedrock of what we’re doing.”

It will provide complete, continuous, structured and enriched asset inventory for IT and security teams managing assets in hybrid environments, according to Pablo Quiroga, Qualys’ Director of Product Management for IT Asset Management.

QSC18: The Need for Security Visibility in the Age of Digital Transformation

Enterprises are moving full steam ahead when it comes to their digital transformation efforts. They’ve aggressively adopted cloud infrastructure and other cloud services, IoT, application containers, serverless functionality, and other technologies that are helping their organization to drive forward.

Those organizations that are way down the road in their digital transformation efforts say that they’ve witnessed improved business decision-making – both when it comes to making better decisions and when it comes to making those decisions more rapidly. They also say that they’ve improved their customer relationships by delivering an improved customer digital experience.

So it’s time to celebrate and declare digital victory, right?

Hold off before we book the band and order the champagne for the big party. In fact, those who want to move forward securely and confidently in their risk and regulatory compliance postures have some challenges ahead.

Threat Hunting: Adoption, Expertise Grow, but Work Remains

Threat hunting, an often misunderstood but powerful security practice, is gaining traction, as more organizations reap benefits from it and get better at it. However, there is still a lot of room for adoption to increase and for practices to improve.

Those were key findings from the SANS Institute’s 2018 threat hunting study, which experts from SANS, Qualys and other companies discussed recently in the two-part webcast “Threat Hunting Is a Process, Not a Thing.”

“Over the past two to three years, threat hunting has been moving from a ‘What is it?’ discussion into a more formal mentality of: ‘This is what it is. Am I doing it right?’,” said Rob Lee, a SANS instructor. “But we’re still in a transition.”

For starters, there’s still considerable confusion about what threat hunting is. For example, it’s very common for many to equate it with reactive practices such as incident response. Rather, threat hunting is by definition proactive. It assumes that the organization’s prevention defenses have been bypassed, and the IT environment breached, without any alerts being triggered.

Using threat intelligence analysis and other tactics, hunters formulate and act on a hypothesis about where the intruders are likely to be lurking in silence while pursuing their nefarious goals.

Stronger Security with Global IT Asset Inventory

On a Friday afternoon before a long holiday weekend, a company’s security operations center receives a potentially serious alert: It appears that a domain controller has been tampered with. After examining event logs and overlaying network traffic, a SOC analyst confirms that a suspicious system did in fact connect to the controller, extracted credentials, and performed other actions. 

Worried this could be a hacker, the SOC team spends hours doing network analysis. Eventually they determine it’s a false alarm: An administrator had logged into the network to check his email with his personal laptop, whose use the company had authorized a month before.

Why did it take the SOC team so long to solve this mystery? They lacked a comprehensive IT asset inventory that would have allowed them to either quickly find that laptop on a list of devices owned by employees and approved for work use, or else determine it was a rogue device.

This hypothetical incident shows the importance of a continuously updated IT asset inventory, which would have slashed the SOC’s investigation time, and made a big difference if instead there had been an attack, according to security experts from SANS Institute and from Qualys.

QSC18 Virtual Edition: Vulnerability Risk Management

When vulnerability risk management is proactive, organizations don’t have to hurriedly react to attacks that exploit bugs for which patches are available, as happened with WannaCry. 

“The vast majority of WannaCry remediation took place as an emergency type process,” Jimmy Graham, a Qualys Director of Product Management, said during QSC18 Virtual Edition.

It’s key to have an integrated breach prevention program with asset inventory, vulnerability management, threat prioritization and patch management, he said

Graham also outlined how Qualys can help customers comprehensively and proactively manage their vulnerability risk.

QSC18 Virtual Edition: Global IT Asset Discovery, Inventory, and Management

Maintaining an IT asset inventory is essential for a strong security posture, but digital transformation has further complicated this already challenging task.

“The volume and variety of assets, including cloud, virtualization, mobility and IoT, is disrupting IT, and security takes center stage,” Pablo Quiroga, a Qualys Director of Product Management, said during QSC18 Virtual Edition.

Consequently, many security teams can’t definitively answer questions like: What are your IT assets? Where are they located? Who are their owners and users? How are assets related?

Having asset-inventory blind spots heightens security risks, which is why most regulations and standards highlight this practice. For instance, the Center for Internet Security’s Top 20 controls begin with inventory and control of hardware and software, because attackers constantly look to exploit vulnerable assets.

In his presentation, titled “Global IT Asset Discovery, Inventory, and Management,” Quiroga explained the importance of a complete and accurate inventory, and how Qualys can help. Read on to learn more.
