Nowadays many of the hacker hack the system through remote access by sending rat and nbt
RAT(remote access trojan):
Most of the remote access of the system is done by this rat. The trojan are similar to the virus but the trojan don't self destruct like the virus.The trojan are downloaded from sites or emails .This rat are saved as cookies in the system ,it seems that it does not affect the system but it has the capability to remotely access the system.Their are different types of trojans like netbus and subeven.Some of the antivirus finds this trojan but powerful trojan change the antivirus into virus.
NBT(net bios tcp/ip):
This is a outdated type of remote access and the latest os mostly don't support NBT. this is also similar to that of FAT.

- Upgrading the firewall will be better solution to this.The firewall control the overall communication between the systems.and the firewall decide to allow or block the program.
- By avoiding the cookies.This can be done by avoiding downloads from untrusted sites.
