Imperva and tel aviv university to the study. The database and application security testing forty more anti-virus products, the results showed that 75% of the products need a month or more time to update the signature. Imperva said the delay will lead to anti-virus software miss new threats signature, and new threats are usually quick to spread.
"We found that now some anti-virus product safety protection is not much, for they have been most anti-virus product confirmation for infection file detection rate is very low, in addition, these COMPAQ Presario CQ61-116TU Laptop DC Power Jack signature database update speed is very slow, even for most anti-virus product has confirmed that virus, these products are still unable to identify.
When using 80 unreported virus test, no surprise, all anti-virus software did not detect any threat. Provide the best protection anti-virus product group contains two free anti-virus products: Avast and Emsisoft. The company said, symantec and McAfee products can well against the virus, the two companies in various tests are very high rank, followed by ESET, Avast, kaspersky and trend of science and technology products.
According to the research shows that, in the face of the Internet is rapid spread of the virus, most anti-virus products are trying to very quickly update the database. In the market leading anti-virus products were found to before the document detection rate was improved, and the speed is about three weeks.
Imperva recommend a kind of common security industry best practices: layered defense or defence in depth method (including tip anti-virus software). Forrester research company vice President and chief analyst Chenxi Wang said that despite the various research shows that anti-virus product bad detection rate, but the enterprise can't completely "abandoned" anti-virus products, they also should not do so. There are many different security techniques can be used to attack detection or mitigate risks, but no universal technology, and no one wants to give up completely anti-virus products.
"Although anti-virus product does not necessarily have the validity of it should be, but when combined with other security measures, these products can be as a defence in depth strategy important constituent, at present does not exist can completely replace anti-virus products or remove the needs of Laptop DC Power Jack."
Enterprise usually combined with endpoint anti-virus products and terminal management products, which can provide enterprises with different functions, such as repair holes or software deployment. Anti-virus alternative products is also already exists. At the same time, anti-virus software vendors have been increasing function (such as based on cloud computing of anti-virus functions) to improve the detection rate, and stored in the cloud, the signature and near real-time update, it can reduce the size of the database or enterprise do not need to be in internal storage signature.
