Access control is one of those topics that often means different things to different people. In its most basic form, it is simply the “restriction of access to a resource." Unfortunately, as you drill down into what that actually means for your organization, things usually get muddy. For some people, it is simply selectively granting user access to...

Unless you’ve been living out in the remotest frontier of some Data Protection Wild West, you will no doubt be aware that a ‘supervisory authority’ Sheriff will soon be riding into town, clutching a lengthy new scroll of law and order in the form of the General Data Protection Regulation (GDPR). ICYMI or simply passed over it as not particularly...

Despite the existence of a number of advanced authentication mechanisms, such as Single Sign-On (SSO), different types of Biometrics, multi-factor authentication, etc., the use of passwords is still the most popular means of authenticating users. The need to generate, and hopefully to remember these passwords, has become even more demanding due to...

A recent experiment conducted at an airport demonstrates that smartphone users are prone to "reckless" behavior when connecting to public WiFi hotspots. In an effort to demonstrate how at risk people are when they connect to public WiFi, security researchers at Avast Software created three open networks next to the Mobile World Congress (MWC)...

Securing the Internet of Things (IoT) has become increasingly difficult. Devices are often shipped with out-of-date operating systems and unmaintained code, which is littered with vulnerabilities. To add to the frustration, traditional security tools cannot be installed on many of these devices. For many users, especially home and SMBs, there are...

With a continued interest in software-as-a-service (SaaS) as a cloud model, concerns about SaaS security are also growing. Total cost of ownership (TCO) used to be the most frequently cited roadblock among potential SaaS customers. But as cloud networks become more frequently used for strategic and mission-critical business applications, security...

It’s the new byword in federal cyber security: “Act as though your network is already compromised.” But what does it mean? DHS’s big cybersecurity programs focus on solutions that either catch the bad guys at the perimeter (Einstein), or harden individual assets to make compromise more difficult (CDM investments in asset management, vulnerability...

Exactly half of all Americans who have fallen victim to ransomware have fulfilled the attackers' demands and paid the ransom. This is just one of the findings of Ransomware. A Victim's Perspective: A study on US and European Internet Users (PDF), a report conducted by Bitdefender in November of last year. For its study, the security firm spoke with...

Fuzz testing is one of the most powerful tools in the bug hunter’s toolset. At a basic level, fuzzing is the art of repeatedly processing crafted test inputs while checking for ill-effects, such as memory corruptions or information disclosures. One of the main advantages of fuzz testing is that it works 24x7 without a break and with no need for...

Developers today recognize the importance of secure software development. Indeed, security was one of the key topics at this month's DeveloperWeek conference in San Francisco. This level of focus should be applauded. At the same time, however, we must recognize that planning for secure software development is not the same thing as implementing it....
