Essay on Managing security issues on corporate computer networks
Introduction
Computers and computer networks have helped organizations realize substantial gains in efficiency and effectiveness resulting in recent trends such as downsizing, empowerment, outsourcing, and constituency work forces. In fact, the root causes of these changes, business process redesign and reengineering, are grounded in the notion that technology enables fundamental changes in the ways that organizations can operate. However, the use of technology has also raised cause for concern.
Hacking has come to be defined increasingly as a potential threat to normative educational ethics and national security alike. In the face of the ethical complexities of hacking, there is perhaps a temptation to adopt the moral certainties contained within the polarized positions of them and us scenario. Such certainties reflect the technical environment within which they are formed:
Computer software is itself a markedly binary discourse. The binary logic of computer technology is vivid in its contrasts between ‘working’ and ‘not working’: on/off; zero/one; right/wrong. As one of the partners of a management consultancy with responsibility for computer reliability put it: Things are either right or wrong. It is a world which greys does not easily inhabit. And a small error doesn’t make it just a little bit wrong. (Woolgar and Russell 1990: 34) http://www.kreps.org/hackers/overheads/9ethicslect.pdf

Network security controls prevent unauthorized individuals from an untrusted network (e.g., the Internet) accessing a trusted zone (e.g., corporate intranet). The golden rule of network access control is, "That which is not explicitly permitted is prohibited." Examples of network safeguards include network firewalls and router screening. Host-based firewalls will be obsolete in the near future for performance reasons (e.g., packet throughput and cryptographic processing).
If the physical security or network is compromised, platform access controls need to prevent unauthorized individuals access to the operating system. To adequately protect platforms, the operating system must provide a strong authentication mechanism before authorizing individual access to its resources....
