Dear experts, <br />
<br />
I am always wanted to know about these 3 addons in our domain computers. These implementations are done by the application and security guys and I am not involved from the network side. <br />
<br />
I want to know what does each application do the computers.<br />
<br />
We have implemented Mcafee antivirus and HOst intrusion detection. <br />
We have implemented something on the IE known as Zscaler and it is string *.pac on the IE LAN settings that the desktop guys need to put to give access to the internet.<br />
<br />
The other issue I have some users are not able to access websites but we can ping them. What does that mean. When I disable HIPs the site will work. <br />
<br />
Another issue I have is some users try to access an internet site but when I ping the site I dont get any replies. Is that a firewall blocking it. <br />
<br />
What will be the function of Zscaler in this scenario. Again I am not a desktop person but I want to clarify and give information on it to technicians interms of training. <br />
<br />
Thanks, Habib

Internet access in corporate environment

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.

Internet Protocols

Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
