Vulnerability and Intrusion
Hackers and malware authors try to take advantage of vulnerabilities, called security holes, in any software. Some people think that a home computer won’t be targeted by hackers because there’s not much on their PC, but they would be mistaken. Cyber-criminals will try to intrude any PC because they can attack a vulnerable application or system so long as it is online. They can then use your PC to attack other computers in your network even if it’s just for fun, or to cause damage and steal personal information. Microsoft is offering the following service and tools to secure the computer from intruders and zero-day malware.
