LinkedIn Faux Pas Shines Light on Certificate Management

Visibility and control of digital certificates remains a challenge for even the largest enterprises, as evidenced by a high profile incident this week affecting Microsoft’s LinkedIn. Users accessing LinkedIn on Tuesday got a warning from their browsers alerting them about an insecure connection. The culprit: An expired TLS certificate.

In a statement to the press, LinkedIn said it experienced a “brief delay” in updating a digital certificate, and stated that member data wasn’t affected. Yet, the incident spotlights a nagging issue that frequently trips even the most technically savvy companies in the world: Digital certificate management.

Qualys SSL Labs’ SSL Pulse, which monitors the quality of SSL/TLS support across 150,000 of the most popular websites in the world, rated about 33% of the sites monitored as having inadequate security in its May report. A few thousand of these sites had expired certificates.

Boost Security with These Gartner-Recommended Projects

Is your security team struggling to decide which projects will slash risk the most without breaking the bank? If so, we believe your security leaders can end analysis paralysis by perusing Gartner’s “Top 10 Security Projects for 2019” report. As its title states, the report recommends ten security projects for 2019, and the projects selected are supported by technologies available today, address the changing needs of cybersecurity and support what Gartner calls a CARTA (Continuous Adaptive Risk and Trust Assessment) strategic approach through risk prioritization.

Below we highlight five of the projects, provide Gartner’s take, offer our opinion, and explain how Qualys can help you implement them.

Windows RDP Remote Code Execution Vulnerability (BlueKeep) – How to Detect and Patch

This month’s Microsoft Patch Tuesday included a very high-risk vulnerability (CVE-2019-0708, aka BlueKeep) in Remote Desktop that impacts Windows XP, Windows 7, Server 2003, Server 2008, and Server 2008 R2. This vulnerability allows an unauthenticated attacker (or malware) to execute code on the vulnerable system. It is very likely that PoC code will be published soon, and this may result in a WannaCry-style attack.

Microsoft has not only released patches for Windows 7, Server 2008 & R2, but also has taken the extra step to issue patches for Windows XP and Server 2003. Patch now!

UPDATE: Network Level Authentication (NLA) partially mitigates this vulnerability. QID 90788 (Microsoft Windows Network Level Authentication Disabled) can be used to find hosts that have NLA disabled. This forces the attacker to have valid credentials in order to perform RCE.

Verizon’s DBIR Highlights Key Drivers of Security Risk

It’s that time of the year when Verizon updates us on the latest trends in the global threat landscape with its Data Breach Investigations Report (DBIR). The findings in this year’s report are based on data provided by more than 70 sources (including Qualys) about more than 41,000 security incidents, including more than 2,000 confirmed data breaches, across a variety of geographies (over 80 countries) and industries. A privileged observation point indeed.

While the very informative 78-page report touches on a wide range of areas,  I’ll focus on three that are particularly relevant for Qualys customers:

  • Who are hackers’ preferred targets, and why
  • The importance of reducing both the time it takes to discover security problems, such as vulnerabilities or breaches, and the time it takes to fix them
  • How lack of visibility, human error and careless misconfigurations heighten organizations’ security risks

Read on to learn more about the evolution (or is it “EVILution”) of the threat landscape in the past year, and find out about recommended actions.
