Difference Between IDS, Firewall & Antivirus

[Karl B.]

IDS = Intrusion Detection system:
There are many forms of IDS. Network IDS and Host IDS are the example.
Network IDS will Generally Capture all Traffic on the network
Host will Capture Traffic for Individual Host
IDS detects attempted attacks using Signature and Patterns much like an Anti Virus App will.

Anti Virus:
They will capture attempted Infections of Files or email, the general infection will be a Trojan and/or Virus/Malware.

Firewall:
Not limited to a Perimeter of a Network, Firewalls can be Sophisticated.
Firewall will scan TCP/IP packets based on Source and Destination then check again a list ( ACL ) and block/Allow traffic accordingly, some firewalls can provide Layer 7 Traffic Scanning ( Deep Packet Inspection) for instance rules can be setup for Applications.

IDS is Intrusion Detection System. it's purpose is to analyze the traffic that goes through it and detects possible intrusions to the system..........
firewall is a network device that in it's basic form separates the internal network from the external network.it allows internal users to go out, but prevents any one from outside the internal network to go in.....
antivirus detectes the infections in the system and heals it depending on the updated version.........

A firewall prevents people from being able to hack into your computer from outside. Your firewall blocks unauthorized connections from other computers/hackers. Firewalls protect the systems network ports from unwanted software traffic.
Anti-virus prevents and gets rid of viruses
A virus program presents harmful software from installing and damaging your computer. Antivirus software protects the computer from infected files.
An Intrusion detection system (IDS) is software and/or hardware designed to detect unwanted attempts at accessing, manipulating, and/or disabling of computer systems, mainly through a network, such as the Internet.

Firewall is a computer program that monitors the system and blocks the entry of viruses and other unwanted programs. The inclusion of a firewall software is a very, very nice addition to McAfee. IDS do Monitors the activities of the system and alerts the user of any intrusion.Kaspersky Anti-Virus 2010 is one of the most efficient antivirus software package.

Anyway, Other people have also shared very nice opinion about this. I am thankful for this.

The antivirus is a highly necessary software for a computer user, cause it protects its PC against many types of intruders and keeps it clean. One should first check a list of reviews of the best antivirus software and after that should choose one to use.

There are many forms of IDS (Network IDS) (Host IDS)

Network IDS will Generally Capture all Traffic on the network
Host will Capture Traffic for Individual Host

IDS detects attempted attacks using Signatrue and Patterns much like an Anti Virus App will.

There is also IPS - Intrusion Prevention System, this can detect an attempted attack and shun or dynamically change an ACL.



Anti Virus - will Capture attempted Infections of Files or email, the general infection will be a trojan and or Virus/Malware, i generally use a AV scanner + Spyware/Malware scanner

Firewall

Generally but not limited to a Perimeter of a Network, Firewalls can be Sophisticated or not depending on Config and features.

Firewall will scan TCP/IP packets based on Source and Destination then check again a list ( ACL ) and block/Allow traffic accordingly, some firewalls can provide Layer 7 Traffic Scaning ( Deep Packet Inspection) for instance rules can be setup for Applications,
Some Firewalls like ASA can have IDS/AV intergrated depending on model.

This is a very Deep Subject and this is my brief desription of them.

If you need more info then Chojin is right use Google to find out more about each subject.
