Difference Between IDS, Firewall & Antivirus

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.........

HI GOOD DAY!

Wow!!!
Really nice info.Thanks for sharing.:)

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.

To prevent any malware or attacks antivirus + firewall is quite enough

anybody used ProteMac NetMine (protemac.com) ? I heard a lot of positive reviews about this app...

For protecting mac you can use ProteMac NetMine too.It’s really good tool.It’s must be helpful to everyone:)

Yeah this is good informaiton i like this actually i didn't know the difference between this but after read out this informaiton i came to know that anyways this is pretty best informaiton i ma using Avast antivirus for virus protection ...
Thanks for this and have a nice day ..........

The prime job of an anivirus is protect your system from computer viruses. Your computer may be standalone or part of network or connected to Internet you need an antivirus program

IDS we mean a system that will be in charge of monitoring the behavior of a network to detect and report any unauthorized intrusions, which can affect the integrity of the network. There is also the IPS, a very similar tool that detects intrusions but also has the ability to block or prevent access after its detection.

Additionally, antivirus solutions will allow detections of malicious code. A good antivirus solution must also detect when a file has some kind of malicious behavior to disallow execution, and thus prevent damage or theft of information.

Finally, a firewall is a security tool that lets you control network traffic. They generally filter network traffic between the Internet and a particular device, and can operate in two different ways: allowing all network packets and only blocking some considered suspect; or by denying all packets, only allowing those that are considered necessary.

IDS/IPS devices and software scan network PACKETS, network traffic. ... IDS and IPS are usually network devices that inspect network packets. While an anti-virus program is a piece of software that inspects malicious files on a host device. For the most part, both use the concept of signature-based databases.

best antivirus solution or the most expensive firewall could be useless if users are not careful about the information they provide on the Internet, or the passwords they are using. Responsible use of the information and devices will allow working environments to be more productive with different technologies in a safer way.
