James Santana Computer Ethics Term Paper Security vs. Privacy Following the terrorist attacks on September of 2001, President George W. Bush signed into law The USA PATRIOT Act. Intended to enhance law enforcement investigatory tools, The Patriot Act made changes to surveillance laws that enabled the U.S government to collect computer information about both American and foreign citizens in unprecedented ways. During the following years, through a series of legislative changes and court decisions

develop security service Computer Security Incident Response Centre (CSIRC) according to case study. Which has moto to provide protection for HHS computer systems and information. To fulfil the security purpose Marlin and his team will take following steps to gain high security for web browsing by using particular browser for organisation. In the report you will find comparison between two different browsers (Internet Explorer and Google Crome). In big organisation like HHS information security is

INTRODUCTION TO CYBER SECURITY “The only system which is truly secure is one which is switched off and unplugged locked in a titanium lined safe, buried in a concrete bunker, and is surrounded by nerve gas and very highly paid armed guards. Even then, I wouldn 't stake my life on it.” -- Gene Spafford, Director, Computer Operations, Audit, and Security Technology (COAST) Project, Purdue University Cyber security can be simply defined as protecting your computer from unwanted access. A simple definition

6) Question C-2.11 (p.109) A bank wants to store the account number of its customer (an 8 digit number) in encrypted form on magnetic stripe ATM cards. Discuss the security of the following methods for storing the account number against an attacker who can read the magnetic stripe: (1) store a cryptographic hash of the account number; (2) store the cipher text of the account number encrypted with the bank’s public key

the computers sold worldwide are represented by portable computers nowadays. An old cliche of computer security is that if an attacker has access to a computer, that attacker has access to the data of that computer. The issues that the specialists in IT domain are facing is to protect the data that may end up in an attacker hands. If a laptop is lost or stolen, the data on it may end up in unauthorized third party 's hands. An average price to pay for an organization if it loses a computer may be

access to. The targets were the Public facing webserver and the internal web server due to the WordPress vulnerabilities. Once an initial shell was created, all attacks were successful although some required changing and modifying some permissions and security files, however, through the initial shell this was all accomplished. Further escalation from one web server to another as well as creating a user on each system was accomplished. Anything touching these two systems is now compromised by an attacker

1. Introduction: A computer is an assembled unit of hardware involving in kilos of hardware components interconnected resulting in a closed circuit where a layer of software so-called operating system runs the whole hardware in accordance with the user commands. The OS is the piece of software which allocates the hardware resources to the processes depending on their priority and usage. It thus protects the hardware components from being used by unwanted processes and safeguarding them in real-time

Define the following terms: a. Network – A group of two or more computer systems connected to each other. b. Node – It is a central or connecting point. c. Router – A router acts as a dispatcher, which determines the next network point for the data to be transferred. d. Hub – A connection point

and bounds over the last few years. This has resulted in a number of computer security breaches on the Internet. Most of the computers that use Internet are vulnerable to attack. Due to this reason, Intrusion Detection systems have grown rapidly and there is an ongoing research since it’s a developing field. ID (Intrusion Detection) is a type of a security management system that gathers and analyzes information to identify security breaches, which include both, attacks from outside the organization
