Network security

In today’s ever changing technological world, network security is a necessity. According to The SANS Institute, a research and educational organization dedicated to “information security training and security certification”, network security is “the process of taking physical and software preventative measures to protect the underlying networking infrastructure from unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure, thereby creating a secure platform for computers, users and programs to perform their permitted critical functions within a secure environment.” ( HYPERLINK "http://www.sans.org" www.sans.org) There are several ways to physically secure a network, some of which include storing the more vulnerable network devices in a locked room with security access restrictions, installing surveillance cameras, removing unused or unsecured computers from workspaces, and securing printers that may retain sensitive document data in memory.

A network allows computers to exchange data. In computer networks, devices exchange data using a data link. The connections are made using cable or wireless connection. Maintaining network security throughout an organization can be quite challenging and is indeed a tough job, but it is attainable and can be achieved. Network security is all about keeping the network safe for all devices and computers on the system. There are certain measures and skills needed to keep a network safe. There are…

their networking departments. A list of a couple of basic network careers can consist of; Network Specialist, Network Technician, Network Administrator, Network Analyst, Network Manager, Network Engineer, and Network Solutions Architect (tom’sIT PRO, 2014). If you want to further your career after working in one of these mentioned fields, you can specialize in these types of careers; Network Security Specialist, Cloud Networking Architect, Networking Research and Development Specialist, Wireless…

Network security has been at the head of some stories in the news. Security is an aspect of the technology field that should be considered at all times. Not only can personal security be breached, the security of others can be affected as well. For example, the incident with the retail company Target, (Vijayan 2014) retailer 's failure to properly segregate systems handling sensitive payment card data from the rest of its network. In this paper, network segment security aspects will be discussed…

Still even with these security measures in place, dubious attackers can breach the security measures and gain access to the data in the following ways [4]. • Cross-site scripting • Cross-site request forgery • Cookie manipulation • OS and SQL injection • Insecure storage • Hidden field manipulation Due to the vulnerabilities listed above, achieving data security in cloud remains a mammoth task. 1) Network Security: When using SaaS, the client transfer sensitive information to the application…

Technology has shaped many parts of our lifestyle’s from movement from one point to another (GPS), all the way to maintaining all of our hard earned funds on a piece of plastic. The question at hand is how this is all protected and who enforces it? Network security has proven beneficial in many cases in today’s society. It continuously monitors the companies system ensuring that unauthorized access isn’t permitted, or as we like to believe keeping our information from falling into the wrong…

are next generation networks. They provide high flexibility, reliability, and security. The main difference between SDN and the traditional network is separation of control and data plane. In SDN, only the controller has the decision-making capabilities. Whereas switches are responsible for traffic forwarding. The controller and switches can be programmed dynamically or as needed. Applications communicate directly with the SDN controller via the northbound interface. This plane is also called as…

Both firewalls and intrusion detection systems are used to monitor network traffic and implement network security policies. Research these technologies and determine how they are similar and how they differ. Are both needed? Explain your answer in a short paper. Firewall From a definition standpoint, a firewall is a hardware or software used in a networked environment to block unauthorized access by individuals while permitting authorized communications to and from the user. The firewall is…

Given the University’s many diverse systems and disparate departmental roles managing the various systems the overall information security plan was not update to date nor consistent. There were obvious holes in the security plan which allowed a hacker to infiltrate the main domain server. The hacker secured administration rights on the server and they managed to infect other systems attached to the network. Thankfully, a trail of clues were found by the administrators. Various suspicious events…

SANS (Sysadmin, Audit, Network and Security) Institute is a privatized company by the United States, which is specialized in 400 training courses including cybersecurity training and information security for security professionals providing proper certification. SANS was established in 1989. The SANS 11 supported programs in the security program publication of 2003 “The many facets of an information security program” by Robert L Behm Jr. Will be discussed below. The information security program…
