Cyber Defense

Background In the recent past, there has been an increasing reliance on technology to undertake numerous aspects of social, political, and economic lives in many countries across the globe. While the reliance on technology has had a positive impact on many aspects of our lives, that reliance also inherently attracts threats such as cyberterrorism. Consequently, cyber defense becomes a crucial element for nations. Cyber defense refers to the deliberate steps taken by governments to protect information that they hold to be sensitive. Cyber threats are not just a danger to the individual countries such as the U.S. that have ...

One of the most interesting laws created by Congress was the Cyber Security Act of 2015. It was created as part of the Omnibus Appropriations Act signed by President Barack Obama that year. The Act limited government use of collected online information and how information could be shared between different nongovernment organizations and different levels of government. The bill may also have increased government oversight as well, considering the fact that the Department of Homeland Security now has increased access to networks to protect against terrorism and espionage. The Act has a “provider exception” (Kerr, 2015), which allows individual ...

INTRODUCTION

Ukraine’s power grid was hacked last December presumably by Russia, showing physical infrastructure affected by cyberattacks Question still loom over the role of cyber attacks on large companies and political bodies (RNC/DNC hacks, WikiLeaks) on the 2016 American election

As such, intelligence and homeland security forces need to turn a stronger eye toward cyber-terror and cybersecurity

I. CYBERTERRORISM

Cyberterrorism increasingly the primary method of attack from foreign bodies and terrorist forces

Three levels of cyberterror: simple-unstructured, advanced-structured, complex-coordinated Attacks occur through Internet communication methods (forums, Skype, VoIP, IM) and DDoS attacks II. CURRENT EFFECTS OF CYBERSECURITY

Privacy from a Multi-National Corporation Perspective

In the digital world, any corporation that seeks to join the multi-national circles must review its ethical standing and responsibilities. Privacy is one of the ethical issues that multi-national corporations must uphold. The ethicality of privacy is linked to the kind of information that individuals or associations reveal to others and the related revelation conditions and safeguards. They must also identify the kind of information that people can keep to themselves without being forced to reveal. Privacy issues are hard to control ranging from the increased surveillance in buildings to the internet (Mason, 1986). Additionally, the internet harbors plenty ...

Even with cyber security systems and measures in place, company cannot think themselves safe, for there are always some loopholes or vulnerabilities left in the defense system. Their exploitation may affect companies in many ways, with impact making itself felt through reputational damage, the loss of delicate information, and expenditure associated with the deployment of additional cyber protection mechanisms. Companies incur heavy financial losses estimated at hundreds of thousands of dollars. The US-based AWS Inc. is the company that should not deem itself as being invincible, as big companies are the first in line for a big-scale attack. To ...

Introduction

Ever since the infamous attack on the World Trade Center which occurred last September 2001, terrorism is a real, pertinent, and primary cause of concern as of late.

How Cyber Security Has Changed?

Over the years, Cybersecurity has changed in the sense that they have become more industrialised and organised. In the past, adversaries were not very organised, as they could compromise an entire system to look for invaluable data and get out. However, contemporary adversaries are extremely purposeful, as most of them target particular information or dat. Furthermore, relatively more destructive ...

Abstract

The United States was called to rethink its security strategies since the September 11, 2001 terrorist attack. Immediately after this catastrophe, the various stakeholders failed to come up with an explanation of why the attack succeeded. Therefore, few months later the Department of Homeland Security (DHS) was established in order to ensure a safer country that was protected from terrorism and other disaster. Since then the DHS made stride in meeting its mandate. One of those mandates is the protection of critical infrastructure since it is vulnerable as a target to attacks or disaster and such would cause immeasurable ...

Question 1 – Packaging a thumb drive for shipment to the lab

Preservation and insulation of a flash drive is a key requirement of its transfer to the forensic laboratory for a subsequent examination. The primary method at the ‘evidence acquisition’ stage is to ensure that the files on the driver were not modified, changed or hidden in any manner. The first step is to make a label to the drive. The label should include information about serial number of the storage device, model type, capacity, and color, country of production and name and surname of a person, who packed the drive.
