Anti-Virus Attack and Defense Research: simple Trojan Analysis and Prevention part1I. preface the development of virus and Trojan Horse technologies today, because they are always complementary, you have me and I have you, so the boundaries between them are often no longer so obvious, each other often uses some of the other's technologies to achieve their own goals, so now many times they are collectively referred to as "malicious code ". This time I

The following articles mainly introduce the implementation and prevention of PHP Mysql injection. In my opinion, the main cause of SQL injection attacks is the following two reasons. 1) The magic_quotes_gpc option in the php configuration file php. ini is disabled. 2).

billion tons (more than 2 billion square meters), which is equivalent to the annual soil erosion volume in China. Debris flows are more active after the earthquake and more active than before the earthquake. Many non-flat troughs become flat troughs after the earthquake. Within five years after the earthquake in the small watershed, the event occurred in the troughs within five years after the earthquake in the large watershed, and the main troughs were extremely active 5-10 years after the e

Understanding bird flu Virus Type "Bird Flu" is short for "bird flu". Its pathogens are the avian influenza virus. There are two types of avian influenza virus: 1. High controllability ( Highly Pathogenic AI ), Such H5 . 2. Low scalability ( Low-pathogenic AI ), Such H5N2 . Virus features The virus is not heat-resistant. 56 ℃ × 3 Hours, 60 ℃ × 30 Minutes or 100 ℃ × 1 Minutes can be killed. Therefore, chicken, eggs and other foods should be coo

. Second, Distributed Denial of Service attacks are even more difficult to prevent. Because the Distributed Denial-of-Service attack data streams come from many sources and attack tools use the random IP technology, the similarity with valid access data streams is increased, making it more difficult to judge and prevent attacks. Attack policy and Prevention At present, with the wide spread of various DDoS attack tools such as TFN, TFN2k, Stacheldra

Today's computers are almost universal, providing great convenience for people to work and study. However, the computer's "crash" is for common computer users, but it becomes an annoyance to get rid of it. Whenever the computer is started, or the operating system is started, or some applications are used, or are preparing to exit the operating system, the "zombie" and the "fierce beast" may be at any time. So how can we avoid computer crashes? Next, I will introduce the cause of the "crash" and
