    In our previous post, we looked at how smart meters were being introduced across multiple countries and regions, and why these devices pose security risks to their users. At their heart, a smart meter is simply... a computer. Let's look at our existing computers - whether they are PCs, smartphones, tablets, or embedded devices. Similarly, these smart meters are communicating via understood technologies: cellular connectivity, power-line networking, or the user's own Internet connection. With that in mind, we have to consider the possible ...

This is sad, true, but it does mean there are ways to harness security technologies like sandboxing and heuristic scanning so that they work together to protect as a stronger whole. The use of heuristics and sandboxing as complementary technologies that cover each other’s weaknesses serves as an effective and efficient way in identifying unknown threats ...

    Evolution is a continuous process, and nothing can exemplify the process better in our industry than the threats we defend against. From simple pranks and nuisances, they've become thieves of information, violators of privacy, destroyers of reputations and even saboteurs of businesses, all for the sake of money. They've also become tools for activists and terrorists of the cyber variety, used to make strong statements against governments or organizations. But as such threats evolve, so must the security solutions that defend against them, ...
