OREANDA-NEWS. Fujitsu Laboratories Ltd. announced that it has developed technology that quickly detects latent malware activity in a network. This technology monitors an internal network to protect against advanced persistent threats (APT) on specific companies or individuals, an increasingly common problem.

APT employ malicious programs known as malware which cannot always be detected by ordinary antivirus software, so security measures that protect the entryways to internal networks are limited. In addition, with malware infections, it is often the case that the attackers, through remotely controlled operations that are disguised in the flow of ordinary communications from outside the network, can carry out hidden activities for long periods of time. This makes it difficult to discover the problem at the exit points of internal networks, such as through unauthorized intrusion-detection systems.

As a method to detect the activity of malware designed to remotely control a terminal, Fujitsu Laboratories focused on the typical communications patterns of latent malware activity within a company's network. The company developed technology to analyze and detect the relationships between multiple communications from outside and within the network. Fujitsu Laboratories then developed technology for the high-speed detection of malware in real time that would work using general-purpose servers. Actual application of this method had been a problematic issue to overcome.

In a connected network of approximately 2000 devices, Fujitsu Laboratories tested and verified that the technology could detect simulated malware activity. This technology makes it possible to quickly detect the latent activity of APT malware in an internal network and protect against data breaches before they occur.
