1.7 SECURITY POLICY

 Before making security policies for a system, first you should analyse how the data is important for you. After knowing the values of your data, you need to develop a set of policies to prevent it. These types of policies are called security policies and may apply to users, department and an organization. The policies are categorized in three different areas listed below:

  • · User Policies
  • · IT Policies
  • · General Policies

User Policies

Under these policies they cover issues related to the users. They define term related to users, what can users do with data or network. It has defined some terms which limit the users to keep the network secure such as access permission, restriction on programs etc. some policies are:

Password Policies: This policy is used to prevent an unauthorized access on user account. It defines procedure for users must change their password often, complexity rule and other items.

Internet Usage: Use of internet, mail, program with password or unencrypted data sent over internet.

System use: They put limitations on the users to use system limited by giving a limited permission on program installation, file sharing, instant messaging etc. 

IT Policies

These policies include general policy for the IT department. Some policies are:

Backup policy: They define policy for what to back up, who back it up, storage, testing etc.

Firewall Policy: They define which port to allow traffic or which blocked.

Client update policy: They define policies to update client.

General Policies

High level program policy: defines how owns other policies, scope, related document and purpose of policies. It covers:

Business continuity policy: in this category, it includes following plan:

  • · Crisis management
  • · Disaster management
  • · Server recovery
  • · Data recovery

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...

3.4 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:...
