Howard related a recent incident caused by the Slammer Worm that made his bank's 13, automated teller machines ATMs unavailable to their customers for approximately 24 hours.

What are some of the challenges facing companies when trying to implement wireless security

Challenges and Solutions Abstract This is information age. There are financial and corporate information, research and analysis reports, trends etc. There are trend-setting and military information. Information is being categorized, as confidential, sensitive and critical. There are automation tools for extracting and gleaning information.

There are management solution products such as content management, knowledge management and document management for managing the collected information.

There are different storage mechanisms for preserving information. Finally, on securing information, there are tools and techniques. In this white paper, we are to discuss about the three important types of information security, such as securing information from hackers, securing information while on transit and securing information stored in systems that can be lost or stolen.

Finally a brief about wireless security has been described here. Information Access Value Vs. Risk The Internet has become the information super highway. The evolving Internet and its related technologies have allowed businesses to communicate in new and strategic ways with various types of people and organizations.

Over the years, there have been additions of feature upon feature to the Internet connections. As the needs have changed, human beings have come across the need of more robust services, faster connections, and more flexibility in what can be done.

In the beginning, services like simple POP3-style email and Web access were the extent of an Internet connection. Today we have site-to-site Virtual Private Networks VPNsclient-side and home-user VPNs, streaming media, Web-based training, exciting Internet applications, e-commerce, and business-to-business extranets.

Thus the Internet evolves towards fulfilling various advanced needs of human society.

On enterprise side, as corporate users increasingly proliferate to information, access beyond the intranet enterprise, the need for ubiquitous, but secure, access for roaming users access multiple channels becomes increasingly prevalent.

More recently, organizations have additionally looked to an Authentication Management Infrastructure AMI model to providing conclusive user authentication. Thus a multifaceted security approach, a combination of security solutions, helps organizations to secure their corporate networks while not impeding resource access.

Internet Security As soon as a computer system is hooked into the Internet, it is exposed to risks of malicious, or even just curious, visitors accessing the system and sniffing for information that was not intended to be shared with anyone.

That is, any connection to the Internet is vulnerable to exploitation. The most basic vulnerability that all connections face is that they could be made unavailable and brings down mission-critical services with them. The worst-case scenario could be a complete system failure, not involving just the host that was serving as the gateway to the Internet, but all other computers to which any path existed from that gateway machine.

Information Security Although information security has always had an important role as technology has advanced, it has become one of the hottest topics in the recent past. As the number of potential targets grows, the sophistication of security threats is increasing.

Today we have some intelligent defenses against attacks, such as denial of service DOS attacks, as routers and other devices can be set to verify source addresses and ignore packets if they are bogus or carry a suspicious pattern. This steady growth has heightened security awareness among organizations struggling to mitigate risk while providing anytime, anyplace access to employees, customers, and partners.

Security awareness is at an all time high as companies become increasingly Web-centric while breaches in security become mainstream news topics.

A Primer on Information Security Authentication supports a very large number of authentication mechanisms. Strong Authentication Strong authentication generally requires at least two of the four types of authentication to be used in combination.

Examples are smart cards plus PIN or biometric, digital certificate plus passwords, physical location, that is, access to a server console plus a password, or biometric plus a PIN.

Biometrics and Certificates Physical: Scans retina, fingerprint, hand geometry or face Behavioral: Analyzes voice or handwriting Digital Signatures Digital signatures are based on a combination of the traditional idea of data hashing with public-key based encryption.

Most hash functions are similar to encryption functions; in fact, some hash functions are just slightly modified encryption functions. Most operate by grabbing a block of data at a time and repeatedly using a simple scrambling algorithm to modify the bits. It is almost impossible for some one to modify the original data in any way while ensuring that the same output will emerge from the hash function.

These hash-based signature algorithms use a cryptographically secure hash function such Message Digest 5 MD-5 or Secure Hash Algorithm SHA to produce a hash value from a given piece of data.

The result is a message digest, which is typically depicted as a long string of hexadecimal digits and manipulated by software as binary data. A digital signature provides compelling evidence that only the intended signer could have created the message.

Suppose interlopers have changed the original message in its transit, and then the decrypted, original message digest would not have matched the recomputed one for the changed data in the message. Verification of the digital signature would fail.TheINQUIRER publishes daily news, reviews on the latest gadgets and devices, and INQdepth articles for tech buffs and hobbyists.

What Are Some Of The Challenges Facing Companies When Trying To Implement Wireless Security. Purpose and Background The accounting profession seems to be ever changing and is currently facing many challenges.

It is a well-known truth that the world we live in is changing at a great speed. The Lifecycle of a Revolution.

In the early days of the public internet, we believed that we were helping build something totally new, a world that would leave behind the shackles of age, of race, of gender, of class, even of law.
