Hi,
I am searching for different types of attacks which are most common for all users. Just pure internet based. The same I am facing from last week and not able to determine the types here. I also want to share the same information with the other people in my place and get them aware about it. I need a list of most possible attacks from internet. I have some details about it but that is half. Thanks in advance.

There are many types of attacks which confuses a user what solution to go in order to avoid. I am listing you some of few. In the first category lies the most normal vulnerabilities. These are called worms. Worm take out advantage of open port in a PC and then connect them self with internet if the firewall of a system is not so strong enough. They are mostly found online. A powerful firewall system is recommended for this.

The other type of wide range of attacks is a common type of DoS / DDoS / synflood. These attacks consist of sending the server a lot of http requests, this requests are for information or connections to exceed its processing capacity. The server overload and then ends. It simulates TCP connection requests, that network management is providing, and makes the attack more successful.

IP spoofing is to spoof an IP address. In the case of a site operator's ip is popped up to several servers. The attacker then tries to pass for one of its machines to access privileged. One more type of common threat is the mailbombing, as its name suggests, the aim to fill up a users inbox with mails. And that too all junk. Other type of attack is the portscan. It is not really an attack. It is conducted to identify open ports on the target of a future attack. The result of portscan can highlight the presence of security vulnerabilities that can be exploited by an attacker.

Hi,

There is a high risk of spy-wares to get installed on your system. You can unknowingly install spy-ware when you install new software, most commonly freeware or shareware P2P (peer-to-peer) file-sharing programs.
