2.0 INTRODUCTION AND 2.1 OBJECTIVES

 2.0 INTRODUCTION

Software vulnerability is defined as we have studied in the previous unit, Virus is a common term understood as software vulnerability by average people. It is a problem that is potentially so dangerous that it threatens the proper functioning of the computer system in today's information age. In this unit you will learn about the unwanted software that is deliberately bad in intent which is “wrote for fun” or “for curiosity” or simply to challenge to create the most destructive software ever built. This software is popularly known as “malware” which is an acronym for malicious software. Malware does nothing useful but rather more harmful. In this unit we will study several types of malware each of which has different goals and propagates differently.

2.1 OBJECTIVES

At the end of this unit you should be able to:

  • · understand and define computer viruses and its evolution;
  • · understand the process of malware infection;
  • · knew different software vulnerabilities;
  • · identify different types of common malicious codes such as Trojan horse, virus and worm;
  • · describe/apply various preventive measures and solutions for malwares; and
  • · various aspects of social engineering attacks.

3.8 SECURE NETWORK DEVICES

 In this unit, we have already learnt that the firewall is only one entry point to your network. Modems, if you allow them to answer incoming calls, can provide an easy means for an attacker to sneak around, your front door (or, firewall). Just as castlesweren't built with moats only in the front, your network needs to be protected at all of its entry points. Secure Modems, DialBack Systems If modem access is to be provided, this should be guarded carefully. The terminal server, or network device that provides dialup access to your network needs to be actively administered, and its logs need to be examined for strange behavior. Its passwords need to be strong not ones that can be guessed. Accounts that aren't actively used should be disabled. In short, it's the easiest way to get into your network from remote: guard it carefully. There are some remote access systems which have the feature of a twopart procedure to establish a connection. The first part is the remote user di...

3.5 SECURITY ISSUES FOR SMALL AND MEDIUM SIZED BUSINESSES

 Small and medium sized businesses use the Internet and networked applications to reach new customers and serve their existing ones more effectively. At the same time, new security threats and legislation puts increased pressure on business networks to be reliable and secure. Business Challenges According to recent studies, security is the biggest challenge facing small and mediumsized businesses. Everchanging security threats from both inside and outside the business network can wreak havoc on business operations, affecting profitability and customer satisfaction. Small and mediumsized businesses must also comply with new regulations and laws created to protect consumer privacy and secure electronic information. Security issues for small and medium – sized businesses are classified into 5 basic categories: Worms and Viruses As per research, Computer worms and viruses remain the most common security threat, with 75 percent of small and medium businesses affected by it.. Worms and v...

3.4 TOPOLOGIES

Image
 In computer networking, topology refers to the layout of connected devices. You can think of a topology as a structure of a network. This shape does not necessarily correspond to the actual physical layout of the devices on the network. Network Topology is the study of the arrangement or mapping of the elements (links, nodes, etc.) of a network interconnection between the nodes. It also determines the strategy for physically expanding the network, in future Topologies can be physical or logical. Physical Topology means the physical design of a network including the devices, location and cable installation. Logical Topology refers to the fact that how data actually transfers in a network as opposed to its design. Following are the considerations for choosing a Topology: · Costing: Some kind of topology may be less expensive compared to others in terms of installation (for example Bus topology). · Length of cable: It is needed to connect machines in a network. · Network scalability:...
