hate to call all the technical skills of the company to show them what a trojan is and what a pony is, and then demonstrate how to upload a Trojan, grandma's, and the popularity of hacker tutorials. Question 2. The website encountered another problem. The last problem was solved for only two months, and the website was hacked and infected. If the boss had to say this time that I had a problem, he would leave immediately, that's why people who do not know more about technology can't talk to each

Intrusion Prevention (IPS) is a new generation of intrusion detection systems (IDS) that make up for the weaknesses of IDs in both proactive and false-positive/negative properties. IPs can identify the intrusion, correlation, impact, direction, and appropriate analysis of events, and then transfer the appropriate infor

First, manageability. An ideal intrusion prevention solution enables security settings and policies to be leveraged by a variety of applications, user groups, and agents, reducing the cost of installing and maintaining large security products. McAfee Intrushield is highly automated, manageable, and flexible enough to implement the installation in phases to avoid the inevitable false positives of the original intr
