The main target for cyber-attacks today is the networked systems. 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. A number of things can be put in place to guarantee that a computer network is secure as we shall be able to see briefly.
User identification policy is the most important step that can be taken to guarantee the security of any networked system. The policy basically lays down the procedures that users should follow in login into the systems and what times they should do so. The policy should also define the hierarchy of network users in a way that access to the system is on a user privilege basis. The top of the tier should comprise of the admins who are responsible for adding new users or modifying existing users. 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 policy should also spell out the password policy. The police dictates the user login credentials that the system is going to accept for all the users in the organization. Password policies are important in removing the loopholes that may exist due to user based mistakes. Once the password policy has been formulated, checks and controls can be added to the system to ensure that users adhere to the policy as has been set down.

Authentication software can be installed to enforce password policies. these systems can be purchased from security agencies whose main concern is 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 password policies should also dictate the level within which information sharing is to take place. Important information, for instance, about the settings of the network systems should never be divulged to people who shouldn’t be privy to it. Additionally, information that is outside the scope of the organization should not be introduced to the network by employers by the use of portable devices such as mobile phones since that could expose your systems to malicious software. Other important details that should be in the policy should also be guidelines on password validity, expiry and consequences that can be faced in case there are violations of the policy.
