Networked systems are a major target for cyber-attacks. This is particularly the case because attacking computers in a network can be easier as opposed to attacking standalone computers. As a result of this, therefore, there is great need to ensure that computers in a network are secured from any forms of intrusions so that the companies information can remain private. As we shall see, there are a number of things that can be put in place to make sure that these systems are secure.
The basic step to securing any computer network is by having a user identification policy within an organization. The essence of the policy is to dictate the authorized times of system access and which users should be able to access the system on the set times. The policy should also define the use tiers which are based on user roles in the system. On the top of the hierarchy, we should have the administrators who are capable of assigning user roles to existing users as well as able to add new users to the system. There can also be room for super users who are above the administrators and who should be charged with the tasks of conducting regular system audits.
The network access policy ought also to define the password policy. The police dictates the user login credentials that the system is going to accept for all the users in the organization. Because not all users may be informed on network security, password policy serves as a tool to sever this loophole. Execution of the policy should be done by putting into place systems that are able to restrict access to compliant users only.
Learning The “Secrets” of Solutions
Enforcing password policy can be done by use of third party authentication software. These software are available from organizations that specialize in network security. By considering the company’s needs, the most suitable software can be bought to enforce the password policy. The right choice of this software should be one that is able to support various encryption algorithms so that users can log in without leaving a hint of their login credential to the attackers or intruders.
The 4 Most Unanswered Questions about Security
The password policies should also set limits on the sharing of the organization’s private information. Important information, for instance, about the settings of the network systems should never be divulged to people who shouldn’t be privy to it. Introduction of alien information by the employers by use of portable devices such as flash disks, floppy disks, DVDs or memory sticks should also be inhibited so that the network is protected from the introduction of malicious software which can be used by the attackers to gain access to the network. Additional information such as the consequences of failing to adhere to the policy, the login credentials validity and duration of use, can also be contained in the password policy of an organization.
