Disadvantages Of The Intranet Management does need to stop control of specific

information, this problem can be minimized but withappropriate prudence.

The other disadvantage of Intranet is security issue Intranet gathered everything in one location which is

really good but if it is not prearranged then you will spoileverything.

The cost of intranet is very high but has lots ofadvantages after implementing

This becomes a complex and expensive task F u n

Software And Hardware RequirementFor An Intranet

you first have to build a network This usually requires a server, web server software such as Apache

or Microsoft IIS and either wifi connections and cards or Ethernetcables and a NIC

Client management function - The client management functiongives the administrator can control the intranet, such as addingusers, removing users and keeping the intranet running smoothly

Employee directory - One of the most used features of any intranetis the employee directory, many employees are always looking forcontact info, whether it is a phone number, email address, fax, titleand some can even include an organizational chart

Project Management - A great time saver is the ability for manypeople within an organization to collaborate on a project whether itis as basic as a mission statement or as complex as a budget

Document share - Your organization will want to make availablecertain information for its members when they need it. This canmean important documents such as reports or other types ofdocuments such as health benefit materials F

Future of The Intranet

Coordination, Cooperation and Collaboration More. More content about people rather than just business artifacts (another

way to look at it is that people become recognized as businessartifacts!)

More non-curated end-user-generated content More metadata (much of it through explicit tagging) More feedback for authors of sites and content (ratings, thumbs, etc.) More open (sharing more internal content with those outside the

firewall) More storage and bandwidth needed (due to exponential content

growth, video, archived conference calls, and voice mail) More form factors (access from home PC, iPad, iPhone, and BlackBerry,

and whatever the Next Big Thing is) F u n

Security Concerns Understanding the security vulnerabilities in an organization Identifying the threats that face your organization; Assessing the risk of each threat Identifying appropriate steps to reduce risk to an acceptable

level Verifying that the system meets the security benchmark

appropriate for a particular organization. Persons who can find access to the intranet can be put into

three categories Those who can enter the site Those who can access the various secured areas Those who can update the sites contents F

Threats - Internal Disable the accounts of employees upon their notification of

termination. Do not wait until their termination date. In thiscase, the logic bomb had been planted before the employeewas actually terminated, but after he knew termination wasimminent

Reinitialize security for systems that were under the terminatedemployees control. Continuously monitor these systems forsecurity violations, such as back doors that are left open.Terminated employees often use these as reentry points.

Install and run antivirus software on each computer on theintranet

Back up systems, applications, and data; deploy off-site storagefor archival backups F

Threats - Internal In 1996, a disgruntled Information Systems employee of a U.S. manufacturer of

measurement and control instruments planted a logic bomb on a company LAN.The bomb detonated ten days after the man had been terminated, wiping out thecompanys research, development, and production software, including its backup systems.The company estimated the cost to recover the damage at $12 million (over the severalyears that would be required to redevelop the software).The employee had been notified that he was to be terminated, but his network accountshad not been disabled until his termination date. He had ample time to plant the bombbefore leaving the company. Had he wanted to do so, he could have opened a back doorto the systems he used, which would have allowed him to commit further damaging acts.This incident shows the need for creating and enforcing realistic security practices,in order to combat internal threats to assets. There is no way to guarantee that employeeswill not commit destructive acts. However, some policies and practices that could havehelped minimize the risk of incurring damages (such as those just cited) include disablingemployee access before termination, running antivirus software on each computer on thenetwork, and monitoring the network to detect intrusive traffic. Because the employee, inthis case, had root privileges to the systems on the network, the Information Technologyteam should have locked down all the systems he administered. F

Threats - External Intranets use Internet technologies, such as e-mail and Hypertext

Transfer Protocol (HTTP), in order to provide corporate resources toemployees. Because these technologies are based on the TCP/IP suiteof protocols, intranets give employees easy access to corporateinformation resources via the Internet, from wherever they might

happen to be: at home, on a business partners site, or in a distantcity.

One result of this access is that employees send identification andauthentication data as well as other sensitive business informationover public networks, as they take care of business from remote

locations. When the logon and authentication communication is notsecured by encryption, amateur programmers working outside thecorporation can intercept and use this sensitive information againstthe company intranet. F
