Mikuni Corporation

Gains comprehensive visibility
into global communications and 
protects critical technical data with
Trend Micro’s security solution

Overview

Mikuni needed to protect highly confidential information such as technical product data from the risk of leakage. Increasing its number of overseas bases compelled the company to respond to the changing and expanding security risks.

Deep Discovery Inspector provides network-wide visibility and effectively prevents malware infections and access to malicious sites. Deep Discovery’s dashboard and reports enables Mikuni to implement processes that continually analyze and improve the company’s security policies and practices.

Challenges

Two key elements of Mikuni’s new approach to security are Trend Micro OfficeScan and Trend Micro Deep Discovery Inspector. OfficeScan protects endpoints against malware, while Deep Discovery provides network-level visibility and protection against targeted attacks and advanced threats.

“Before Deep Discovery, we used its predecessor, Trend Micro Threat Management Solution, and we made the switch as soon as Deep Discovery was released. The solution monitors communications to our Odawara and Kikugawa plants and foreign bases, as well as communications to the Internet. In addition to conventional pattern-matching anti-malware measures, the solution with advanced behavioral analysis enables us to discover any malicious communications within our company in their initial stages,” says Inamori.

Deep Discovery is the keystone of Mikuni’s process for addressing security issues. Whenever Deep Discovery’s centralized management console or daily event logs present an alert regarding suspicious or malicious communications, an IT security personnel can dig down the events to pinpoint the location of the device that originated the suspect communications instantly on the console. “Because locating the source of a suspect communication is as simple as clicking the prompts on the screen, even staff with no specialist knowledge can carry it out easily. This is one of Deep Discovery’s major benefits,” says Inamori.

Once source devices are pinpoint, onsite IT personnel must then investigate to specify and correct the root causes. If this cannot be accomplished within two hours, Mikuni’s policy is to re-install the operating system of the affected device, in order to avoid a lengthy investigation and potential operational disruptions. In either case, Deep Discovery is then used to closely monitor all subsequent traffic to and from the affected device, to ensure the problem has been eliminated.

“Although reinstalling the operating system may sound a little extreme, it is essential for our company to promptly solve detected issues and continue business without interruption. We feel that it is an effective approach in terms of not wasting resources in the response,” explains Inamori.

Deep Discovery’s powerful and flexible reporting functions also provide invaluable data to Mikuni’s global IT groups, both to capture network traffic status, and to prepare reports for corporate management. “Reports which carry the seal of approval of a security specialist with the standing of Trend Micro hold much more power to persuade management. There is a particularly high degree of trust and sense of security that there will be no incidents while protected by Trend Micro solutions,” says Inamori.

You cannot just deploy security measures and then forget about them. We prepared a system which covers the entire threat-response cycle, from understanding and analyzing communications to planning and implementing countermeasures.

Results

This system has successfully identified and eliminated security threats on several occasions, including one in which the source of the threat was determined to have been a contaminated USB memory stick. This incident led to a new company rule barring the use of such devices.

“Deep Discovery logs also let us see when employees access sites unrelated to business activities. Based on these URLs found, we set a policy to block access to these sites and complete risk management practices amongst our employees,” explains Inamori. As a result, the company reports that it has almost zero suspicious communications. Deep Discovery has helped to improve the security consciousness of end users and has eliminated the primary factors of risks.

The next step in Mikuni’s security planning is to implement enhanced security measures against increasingly common targeted email attacks, and it is currently investigating methods to achieve this.

“Trend Micro OfficeScan and Deep Discovery Inspector both greatly support our security measures, in an integrated manner; this gives us a tremendous sense of security. We have enormous faith that Trend Micro will continue to provide us with innovative and effective security solutions in the future,” concludes Yamagishi.
