Trend Micro has outlined a product-development strategy it calls “Custom Defense” The strategy is intended to augment traditional signature-based anti-malware defense with custom-designed signatures to thwart stealthy, targeted attacks. The Custom Defense strategy builds on Trend Micro’s security appliance called Deep Discovery, intended to watch for signs of intruders. By year-end, Trend Micro expects to have the ability to generate custom antivirus signatures as well. The concept with custom signatures is to be able to add them to Trend’s email protection product.”]
