    • A system and method analyzes queries in a computer network, and identifies problem-causing queries that could be harmful to the system. If a query does not match any queries in a database, the query is transmitted to its destination. If a query matches a query in the database, that query is blocked from transmission to the destination. If a query is transmitted to its destination, and it is later determined that query caused a problem on that destination, that query is added to the database of queries. In one embodiment, a query that does not cause any problems is written to a pool of current up-to-date backup databases that may be used if the main system goes down. In another embodiment, the system tests variants of a query that caused a problem at the destination to attempt to discover other queries that could cause a problem.
    • 系统和方法在计算机网络中分析查询,并识别可能对系统有害的导致问题的查询。 如果查询与数据库中的任何查询不匹配,则将查询发送到其目标。 如果查询与数据库中的查询相匹配,该查询将被阻止传输到目的地。 如果将查询传输到其目标,并且稍后确定该查询导致该目标上的问题,该查询将被添加到查询数据库。 在一个实施例中,将不会引起任何问题的查询写入当前最新备份数据库的池中,如果主系统停机,可以使用该数据库。 在另一个实施例中,系统测试在目的地导致问题的查询的变体以尝试发现可能导致问题的其他查询。
