...information security. Ensuring a secure network involves good design, implementation, and maintenance. The information in your organization is potentially vulnerable to both internal and external threats. Identify these threats and create methods of countering them before they happen. Be able to identify the potential physical, operational, and management policy decisions that affect your information security efforts. It isn’t good enough to have a plan if the plan is unsound or has gaping holes. You must make sure that the plans you develop and the procedures you follow to ensure security make sense for the organization and are effective in addressing the organization’s needs. Be able to explain the relative advantages of the technologies available to you for authentication. You have many tools available to establish authentication processes. Some of these tools start with a password and user ID. Others involve physical devices or the physical characteristics of the person who is requesting authentication. This area is referred to as I&A. Be able to explain the relative capabilities of the technologies available to you for network security. In most situations, you can create virtual LANs, create connections that are encrypted, and isolate high-risk assets from low-risk assets. You can do so using tunneling, DMZs, and network segmenting. Be able to identify and describe the goals of information security. The three primary goals of information security are prevention...

...IT@Intel Brief Intel Information Technology Computer Manufacturing Enterprise Security Network Access Control: User and Device Authentication August 2005 Intel IT is piloting new security methods to provide network access control by authenticating devices as well as users. Since networking has evolved to support both wired and wireless access, securing corporate networks from attack has become ever more essential. Therefore, to effectively enforce network access control policies in a proactive manner, we are developing a method to authenticate users and devices before they connect to the network. Network Access Control at Intel • Over 90,000 employees worldwide • 80 percent of knowledge workers are mobile and unwired • Over 50,000 remote access users Background As a global corporation, Intel IT supports more than 90,000 employees and contractors all over the world, and 80 percent of our knowledge workers are mobile and unwired. Network access depends more and more upon wireless LANs and WANs, as well as virtual private network (VPN) remote access. All of these technologies have the potential to open our network perimeter to threats. When we considered the threat of viruses and worms, it was evident that we needed additional controls to secure the enterprise network and its information assets from unauthorized devices and unauthorized people. Figure 1 shows how we could authenticate devices and users as part of the authentication pyramid. Figure 1. Authentication...

...Denver, Colorado * Los Angeles, California * Montreal, Canada * New York City, New York * Washington, D.C The North American offices have a total of 5,000 employees who use desktop, laptops, and wireless devices. All offices deal with several sensitive applications. Management from each office shares application information hosted at the corporate office. Database research and industry, and there has also been increasing interest in the problem of building accurate data mining models over aggregate data, while protecting privacy at the level of individual records. Instead of building walls around servers or hard drives, a protective layer of encryption is provided around specific sensitive data-items or objects. This prevents outside attacks as well as infiltration from within the server itself. This also allows the security administrator to define which data stored in databases are sensitive and thereby focusing the protection only on the sensitive data, which in turn minimizes the delays or burdens on the system that may occur from other bulk encryption methods. Encryption can provide strong security for data at rest, but developing a database encryption strategy must take many factors into consideration. Design an enterprise encryption strategy –a public key infrastructure (PKI) that supports internal employees, external business partners, and clients. Include the design and reasoning for using the select encryption strategy. The strategy...

...common email encryption is called PKI. In order to open the encrypted file an exchange of keys is done. Many infrastructures such as banks rely on secure transmission protocols to prevent a catastrophic breach of security. Secure transmissions are put in place to prevent attacks such as ARP spoofing and general data loss. Software and hardware implementations which attempt to detect and prevent the unauthorized transmission of information from the computer systems to an organization on the outside may be referred to as Information Leak Detection and Prevention (ILDP), Information Leak Prevention (ILP), Content Monitoring and Filtering (CMF) or Extrusion Prevention systems and are used in connection with other methods to ensure secure transmission of data. ------------------------------------------------- [edit]Secure transmission over wireless infrastructure Main article: Wired Equivalent Privacy WEP is a deprecated algorithm to secure IEEE 802.11 wireless networks. Wireless networks broadcast messages using radio, so are more susceptible to eavesdropping than wired networks. When introduced in 1999, WEP was intended to provide confidentiality comparable to that of a traditional wired network. A later system, called Wi-Fi Protected Access (WPA) has since been developed to provide stronger security. ------------------------------------------------- [edit]Web-based secure transmission Main article: secure socket layer Transport Layer Security (TLS) and its predecessor, Secure...

...INFORMATION SECURITY IN THE DIGITAL WORLD NAME Abstract Information security is the process of detecting and preventing unauthorized users access to your network, computer, and ultimately your personal information. Information security is huge and many casual users do not even think about it, or if they do, only as an afterthought. This is one of the worst things that you can do in this day and age especially with the abundance of technology in our everyday lives. Everyone should care and be concerned about all levels of information security as a breach in security could mean financial ruin, personal embarrassment, stolen trade secrets, and much more. Intruders come from a wide variety of places and could be someone as simple as your next door neighbor stealing wireless internet from you to Chinese agents stealing classified weapon system designs from the US government. With the complexities of software these days there will always be vulnerabilities to expose and utilize which is why every user needs to stay on top of their own security. This typically means applying the latest operating system and software patches, maintaining a firewall and up to date virus scanning software, being intelligent about where you web surf and what you click on, and just being as smart in the digital world as you are in the physical world. This paper will cover some of the types of network attacks that are out there...
