The virus countermeasure software is "What are the same?" "Is there no effect?" - Let's answer that question: Sakaei Hagiwara's Information Security Counseling Room (page 1/3)

　The other day, the statement of Symantec Senior Vice President Brian Dai became a big topic.When I am a company consultant, "I know that virus software seems to be important, but is it necessary?"I often ask.

　I have been listening to the latest status of virus software and current problems with a confidentiality contract with a virus software maker.It is within the range that does not violate the contract, but this time we will explain questions about virus software.

Are all the virus software the same?

　My view is "different."In the past, virus software was largely divided into two parts: "virus countermeasures on the Internet" and "unauthorized program countermeasures inside PC".In Akihabara, the two types were separated properly and were lined up in stores.At that time, various words such as "spyware", "pest", "malware", and "fraudulent software" were tolerated.Under such circumstances, the current “comprehensive measures software” manufacturer has emerged.

　In the first place, the "virus countermeasures on the net" software and the "unauthorized program countermeasures inside the PC" software seemed the same, but the detection and extermination method were clearly different.Especially for technicians who had developed viruses on the Internet, the detection and extermination rate of fraudulent software that could not use the detection method did not improve and had a hard time.

　In the evening edition of the Asahi Shimbun on March 6, 2003, it was reported that "Net banking is stolen 16 million yen."It is a misconduct using a famous key logger.Then, in the 2004 version of the 2004 edition of the virus software, all of them say that spyware is also detected, "protection from spyware adware", "spyware and key stroke programs (keylogers are also this kind)".is what happened.

　However, when I verified it at that time, although the spyware that could be found in the world and normally, it was certainly detected, but it is only a part, and the detection accuracy is compared to normal pests and spy -only software.I didn't see it.He gave many lectures, "It's not a lie but close to fraud."

　I don't think it was an effect, but each manufacturer absorbed and merged with a full -time software company.As a result, it is now a “comprehensive measures software” manufacturer that can be used in either, and there are few software companies specializing in unauthorized programs such as spies and pests.

　It is a virus software that has grown in this background, but each has its own characteristics.However, due to capital and transactions, companies often use it without any objection to major software.For the management side, it is a fact that one is more preferred.

Is free software enough?

　Occasionally, "How about free virus software?"In the case of a corporation, there are not many places to use free software in consideration of a responsibility problem.If free software causes enormous damage, you will not be able to make excuses and you will not complain to the manufacturer."I'm using it for free."

　In addition, many individuals have the argument that "XX is good" after looking at the comparison site of dozens of virus software.In many cases, most companies have tried once and decides that they are "light and moderately protected" or "those with high ERA, even if they are expensive and heavy."

　Many of these comparison sites can be referred to as good citizens' actions, and in foreign countries, they have obtained subsidies from the government and publish the "crown" of a third -party evaluation organization.However, it is important to note that in some cases, some sponsors have given the sponsor and some have suspicious results.If you have a deviation from the site operator's identity and other evaluation sites (government systems are desirable), please check the contents at your own risk.
