I. Vulnerability Assessments
Reviewing the current network configuration, I have discovered several vulnerabilities in regards to the organization's network.
Starting with the current router, the NetGear WGR614 is an 802.11b wireless networking device originally released in 2002 and has an approximate 1650 Ft. range. Outside of no mention of the physical location of the device in the synopsis, which is concerning, a simple review of the device indicates that the device is technologically obsolete. For instance, the NetGear WGR614 came initially with wired equivalent privacy (WEP) only, and did not receive an update to provide it Wi-Fi Protected Access 2 - Pre-Shared Key, until 2 years after its release (). While the use of this router may deter the most basic intrusion attempts from individuals searching for quick access to a network. It was

The lack of a standardized email system administered by the firm is concerning, as encryption of some standard email web browsers is not sufficient enough to ensure the proper safeguarding of email traffic. While it is possible that most web browsers utilize Pretty Good Privacy (PGP) for email encryption at the very least, without the standardization of email to one type of system, the firm is unable to ensure proper encryption. Furthermore, without the ability for someone in the firm to administer users email, we are unable to control email traffic to slow or reject spam or suspicious user attacks
Another concern for the network, is the owner’s usage of a personal IPad to check and respond to email messages. No mention was made in regards to the type of encryption technology utilized to send and receive emails. Usage of email encryption, which is available for devices such as IPad’s, ensures that emails received are confidential and/or only received by the appropriate
Email security services will include blocking ransomware and emerging threats with the highest effectiveness and accuracy, stopping new and sophisticated threats such as ransomware, spear phishing, and business email compromise. Spear phishing will be prevented by having a comprehensive defense that includes multiple layers of protection, strong isolation , deep visibility and dynamic security awareness. Attacks will be contained and responses will be orchestrated across endpoint security and web gateways by remediating attacks and blacklisting threats. Dynamically classify impostor email and other threats that don't involve malware. Sender-recipient relationship, domain reputation, email headers, envelope attributes and email content will be analyzed. Custom rules will be integrated allowing group and user level controls to meet the needs of the client. Quarantines will enable the customer to separate email
Don’t hesitate to bring in experts to make sure your network is configured properly. Correct assessment, however the lesson doesn’t factor in when to bring in an expert. Despite an over-reliance on technology, there needs to be a timeframe for this expert and how their analysis will support overall technological requirements.
National security in the United States is extremely important and requires extensive risk management measures including strategic, exercise, operational and capability-based planning, research, development, and making resource decisions in order to address real-world events, maintain safety, security and resilience (Department of Homeland Security [DHS], 2011). The national security and threat assessment process consists of identifying the risk and establishing an objective, analyzing the relative risks and environment, exploring alternatives and devising a plan of action for risk management, decision making and continued monitoring and surveillance (DHS, 2011). Identifying risks entails establishing a context to define the risk, considering related risks and varying scenarios, including the unlikely ones, which then leads to the analysis phase; gathering data and utilizing various methodologies and analysis data software systems to survey incidence rates, relative risks, prevalence rates, likelihood and probable outcomes (DHS, 2011). These two key phases lay the foundation to explore alternatives and devise action plans. Threats, vulnerabilities and consequences (TCV) are also a key component of many national security risk management assessments because it directly relates to safety and operation capabilities, but the text stress that it should not be included in the framework of every assessment because it is not always applicable (DHS, 2011).
Penetration testing - using tools and processes to scan the network environment for vulnerabilities, [03& T, J.K et al. 2002] there are many different types of vulnerability assessments. Penetration Testing focuses on understanding the vulnerabilities of components that you’ve made available on the network as seen from the perspective of a skilful and determined attacker who has access to that network. It will provide a thorough overview of the ...
Wi-Fi facilitates ease of use and is getting increasingly popular with homes and businesses. Multiple Wi-Fi Access Points can be located in a given area. Wi-Fi security issues continue to be a problem, as the number of Access Points grows.
Wi-Fi (Wireless Network) or 802.11 networking is a phenomenal way of providing Internet wirelessly at a low cost. Using radio waves, a wireless network connects a PC, mobile phone or just about anything that connects to the internet wirelessly by a router. By transmitting signals at 2.4 or 5 GHz it allows the waves to transmit more data at a faster rate. Typical Wi-Fi standards are 802.11a, b, g, n, or ac and they can switch up the frequency depending on the model (Brain). Families can create their own wireless network that can be shared between family members without the use of hooking all their devices up to the modem and can also protect their home network from potential hackers with the use of a TKIP or AES encryption. Businesses can also create a “hotspot” which is an area that has wireless networks for free or at a set fee. This is extremely convenient for commuters that need internet access while they are at work, waiting on a plane, or just sitting at a coffee spot without the need for wires(Cox).
This paper is going to discuss wireless security from a broad view where I will go into why wireless security is so important, especially today as the ways in which we communicate is changing dramatically. From there I will discuss the multiple wireless security options that are available to give a better understanding of the options given. Then I will go into why exactly not protecting your wireless can be so dangerous with some descriptions on the most dangerous wireless attacks out there today. Finally, I will then discuss how we can better prepare for these types of attacks with a synopsis on several effective security methods that will help to ensure data is securely passed and kept hidden. Wireless is everywhere today whether at home working from your WIFI network to work where you might be linked to a wireless network or even through your phone through a 3G or 4G network to connect to an open wireless network.
Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
Electronic Mail, a means of communication that is growing at a very rapid rate. In this paper, I will write about introduction of e-mail, the advantage and disadvantage of e-mail, mailing lists, sending an e-mail message, sending attachments, e-mail improvement, and security features. Introduction of Electronic Mail Electronic mail (E-mail) has become popular and easy way of communication in this decade. E-mail is a method of sending and receiving document or message from one person to another. E-mail is not only replacement for postal mail and telephones, and also it is a new medium. E-mail send plain text, images, audio, spreadsheets, computer programs can attach to an e-mail message. Using the e-mail, you must have a computer on a network. The computer must require a modem and phone line. Sending and receiving e-mail needs an e-mail program. Every e-mail user requires an e-mail address. This e-mail address is similar to a postal address. E-mail address is written as username@domain, for instance, PCLEE@juno.com. The username is used for sending and receiving e-mail.
Communication is important in life. Companies need to communicate with other companies and customers. The managers also need to communicate with the staff. The technology provides us with many means of communication, the most important of which is e-mail.
Corporate Networks in organisations can be complex structures that “requires a great deal of attention” (Clemm 2007). Even small companies can have quite complex networks that are a considerable investment to the business. The notion that corporate network management is a cost to a business rather than a continual beneficial investment is a naive assumption that requires further investigation to the benefits that network management brings. Clemm (Clemm 2007) states in his text that the ultimate goal of network management “is to reduce and minimize total cost of ownership”, improving operational efficiency and lowering cost. Clemm (Clemm 2007) also notes that “Network Management is not just related to cost and quality”, which will be an continual concept presented throughout the report. The report will address key issues with corporate network management and ultimately argue and justify that corporate network management must be seen as a positive benefit to the business and not as a continual expense. The supporting articles will also provide sound evidence that networking is crucial to a business’s processes and production which can be seen from the OpenSSL Heartbleed Security vulnerability fiasco (Nieva 2014) or the QANTAS Amadeus system failure (Heasley 2012).
New technologies are allowing us to do things faster, easier, and more efficiently than ever before. Almost every new innovation in technology improves the speed and productivity of any task at hand. Electronic mail (E-mail) is possibly one of the greatest things to happen to the world. Despite this, there are people who find difficulties in using either E-mail or conventional mail. To help decide whether to use E-mail or the United States postal Service, a comparison of each one’s speed, ease of use, reliability, and cost is a helping factor.
A hazard is defined as an activity or object that has the potential to cause harm if contact is made with the person, object or activity (MHS, 1996; Harmse, 2007; HSE, 2006). These hazards in a work place need to be identified and dealt with accordingly to prevent any harm to employees or any individual acquainted to a certain activity or establishment. The key roles and principles of occupational hygiene are Anticipation, Identification, Evaluation and Control (Schoeman and van den Heever, 2014; Harmse, 2008; SAMTRAC, 2012). To practise in accordance to the above principle; a hazard identification and risk assessment needs to be conducted. Anticipation is the foreseeing of the activity
The network management plan and security plan is important to help the company figure out how they will improve its network and security procedures for the company. Planning involves outlining objectiv...
Email (electronic mail) was one of the biggest breakthroughs in communication when the internet was commercialized. With email, it became possible to send messages and letters across the world in a matter of seconds to the recipients address. Email was used as an alternative to conventional mail or snail' mail, as the term was introduced to describe its speed. As technology improved, it became possible to attach' documents, photographs and even sound clips or songs to emails which made mail by post redundant. Emails used packet switching software whereby the email was broken down into packets' and sent via the internet to the recipient.
