The vast majority of the world’s most popular websites lack adequate security controls, according to a recent survey.

Mozilla’s April King used the Mozilla Observatory tool to conduct a survey of the top 1 million websites. She found that 93 percent failed to adopt technologies to protect against cross-site scripting (XSS) vulnerabilities, man-in-the-middle (MitM) attacks and cookie hijacking, according to her post on the Mozilla Security Blog.

Website Security Woes

Of the 13 website security features the Observatory analyzed, two of the most infrequently used were content security policy (CSP) and subresource integrity, both of which can eliminate unsafe JavaScript actions that could lead to XSS vulnerabilities. These features were given considerable weight in the Observatory score.

Other security measures evaluated in the survey include encryption and X-XSS-Protection (XXSSP) — a helpful process for minimizing XSS attacks. The report also considered public key pinning, which can limit the use of fraudulent certificates.

The Good News

The survey was not all bad news, however. In the eight months since the last major Observatory survey in October 2016, failing grades decreased by 2.8 percent, King noted. That means over 27,000 of the world’s largest sites improved. Furthermore, sites earning an A rating jumped by 142 percent, B ratings grew by 79 percent and those with a C grade increased by 90 percent.

Better security scores could be a result of more widespread security technology. For example, the number of sites that have enabled HTTPS grew 36 percent in the past eight months — meaning that 119,000 more websites are now using it.

Building a Safer Internet

Those positive vibes should continue as security awareness and controls become more attainable. “With tools that are free and easy to use, like Observatory, we can begin to see a common framework for building websites,” said King, according to Threatpost. “This type of tool is pushing awareness back into the tool chain and making it very easy for people to implement.”

The problems of securing a website remain largely unsolved. There are differing security standards, for instance — the documentation for which may be hard for site operators to find. But resources such as the Observatory tool can itemize specific steps to increase security and highlight weak points. If widely used, these tools can help create a safer internet for website operators and users alike.

How Do You Plan to Celebrate National Computer Security Day?

In October 2022, the world marked the 19th Cybersecurity Awareness Month. October might be over, but employers can still talk about awareness of digital threats. We all have another chance before then: National Computer Security Day. The History of National Computer Security Day The origins of National Computer Security Day trace back to 1988 and the Washington, D.C. chapter of the Association for Computing Machinery’s Special Interest Group on Security, Audit and Control.

Abuse of Privilege Enabled Long-Term DIB Organization Hack

From November 2021 through January 2022, the Cybersecurity and Infrastructure Security Agency (CISA) responded to an advanced cyberattack on a Defense Industrial Base (DIB) organization’s enterprise network. During that time frame, advanced persistent threat (APT) adversaries used an open-source toolkit called Impacket to breach the environment and further penetrate the organization’s network. Even worse, CISA reported that multiple APT groups may have hacked into the organization’s network. Data breaches such as these are almost always the result of compromised endpoints…

Subsequently, alert fatigue is already a problem for analysts overwhelmed with security tasks. With the continued shortage of qualified staff, organizations are looking for automation to…

Worms of Wisdom: How WannaCry Shapes Cybersecurity Today

WannaCry wasn't a particularly complex or innovative ransomware attack. What made it unique, however, was its rapid spread. Using the EternalBlue exploit, malware could quickly move from device to device, leveraging a flaw in the Microsoft Windows Server Message Block (SMB) protocol. As a result, when the WannaCry "ransomworm" hit networks in 2017, it expanded to wreak havoc on high-profile systems worldwide. While the discovery of a "kill switch" in the code blunted the spread of the attack and newly…
