...data that resides in and among computer systems must be protected against security threats that exploit vulnerabilities. Organizations must therefore impose appropriate controls to monitor for, deter and prevent security breaches. Three areas have been considered, in a typical sense, as the basic critical security requirements for data protection: confidentiality is used to assure privacy; principles of integrity assure systems are changed in accordance with authorized practices; and, availability is applied to maintain proper system functions to sustain service delivery (Dhillon, 2007, p. 19). These security requirements are represented in Figure 1, Classic Critical Security Requirements. This figure depicts the cross-domain solutions of informal controls, also known as human relationships, and formal and technical controls, which provide for organizational and physical information security controls, respectively. Two additional security requirements have recently been added that are of particular importance to networked environments because attacks now extend far beyond traditional firewall perimeters. These are authentication, which is used to assure a message actually comes from the source it claims to have originated; and, nonrepudiation, which can be applied to prevent an entity from denying performance of a particular action related to handling data, thereby assuring validity of content and origin. Figure 2, Core Data Security Set, depicts the interrelationship of...

...Claudia Goodman IT302 Homework 2 Security-Enhanced Linux The NSA has long been involved with the computer security research community in investigating a wide range of computer security topics including operating system security. It recognizes the critical role of operating system security mechanisms in supporting security at higher levels. End systems must be able to enforce confidentiality and integrity requirements to provide system security. Unfortunately, existing mainstream operating systems lack the critical security feature required for enforcing separation: mandatory access control. Application security mechanisms are vulnerable to tampering and bypass, and malicious or flawed applications can easily cause failures in system security. The results of several of these projects in this area have yielded a strong, flexible mandatory access control architecture called Flask. This has been mainstreamed into Linux and ported to several other systems, including the Solaris™ operating system, the FreeBSD® operating system, and the Darwin kernel. This provides a mechanism to enforce the separation of information based on confidentiality and integrity requirements and it allows threats of tampering and bypassing of application security mechanisms to be addressed while enabling the confinement of damage that can be caused by malicious or flawed applications. This is simply an example of how mandatory access controls that can confine the actions of any process, including an...

...As an Information Security Engineer for a large multi-international corporation, that has just suffered multiple security breaches that have threatened customers' trust in the fact that their confidential data and financial assets such as Credit-card information; one must implement security measures that will protect the network through a vulnerable wireless connection within the organization, while also providing a security plan that will protect against weak access-control policies within the organization. The first step of protecting against Credit-card information through a vulnerable wireless connection within the organization would be to first protect your wireless broadband from cyber-attacks, which don’t involve any costly measures. One must always remember to lock down the wireless network. By default the password for your panel is often a standard one set-up by the manufacturer (for example ‘admin’). It’s very important that you change this as soon as possible, because it would me that many hackers would already have the password for it. When picking a strong password use a case sensitive combination of alphabets and numbers, six characters and more. Also remember to make it something unique and not the same as something else like your Facebook or Twitter password. Next too consider is the fact that most routers come with a WEP or WPA key built in for good measure, and each router has a different code so there is no need to stress when it comes to this aspect.

...Information Systems are the backbone to support the management, operation and decision function of every business or organization. Information Systems (IS) are composed of hardware, software, infrastructure and trained personnel where all the information are digitally processed and be accessible for the use of authorized personnel. Let first resume Information Systems history: • In the 70’s, IS was made of mainframe computers were the data was centralized. They have fewer functions like payroll, inventory and billing process. • Then in the 80’s came the automation process where computers and peripheral devices started to be connected using Local Area Network (LAN). Also started the use of word processors and spreadsheets to automate the flow of information within departments. • In the 90’s the advance of technology brings the ability of corporation to stablish connection between branches and remote offices using Wide Area Network (WAN). Corporations started to look for systems and data integration, leaving behind stand-alone systems. • In the 2000, the introduction of the Internet expand WAN for global enterprises and business involved in supply chain and distribution between countries. Data sharing across systems was the main focus for corporations. The use of electronic mail (email) become a global standard communication between corporations. • In Current time, the advance on technology brings Wireless connectivity where new devices like tablet pc and smartphones...

...Fundamentals of Information Systems Security CSS150-1302B-02 Phase 1 Discussion Board 2 Christopher Smith May 22, 2013 Hello all. At this time we are going to discuss three out of the seven domains of a typical IT infrastructure. The three that have I chosen to discuss have the greatest impact on your day to day work lives. The domains with the most impact are the user domain (you), the workstation domain (your computer), and the remote access domain (work from home users). The information within the seven domains is meant as internal use only. We at Richman Investments take the security of our, and our customer’s information very seriously. We will be discussing the three domains that are the most susceptible to attack. The human factor is the biggest variable in these domains. We will be discussing the safeguards put in place here at our firm. The largest of the three domains we will be discussing is the user domain. As stated above this means you. Included in our yearly security awareness training is a recap of our acceptable use policy (also found in your employee handbook). The acceptable use policy mandates what you cannot do on our network. This includes not using personal devices on any wired/wireless networks within our property, and using storage devices not provided to you by the company. Any files you need to access away from the office should be stored on our secure online storage system only. As the user it is your responsibility to be diligent and keep your...

...recommendations for improving the Security configuration and monitoring of their IEEE 802.11 wireless local area networks (WLANs) and their devices connecting to those networks. The scope of this publication is limited to unclassified wireless networks and unclassified facilities within range of unclassified wireless networks. This publication supplements other NIST publications by consolidating and strengthening their key recommendations, and it points readers to the appropriate NIST publications for additional information (see Appendix C for the full list of references and Appendix A for a list of major security controls relevant for WLAN security). This publication does not eliminate the need to follow recommendations in other NIST publications, such as [SP800-48] and [SP800-97]. If there is a conflict between recommendations in this publication and another NIST wireless publication, the recommendation in this publication takes precedence. NIST Special Publication 800-53 is part of the Special Publication 800-series that reports on the Information Technology Laboratory’s (ITL) research, guidelines, and outreach efforts in information system security, and on ITL’s activity with industry, government, and academic organizations.
