The main target for cyber-attacks today is the networked systems. This can be attributed to the fact that attackers are more certain of gaining access to the entire system by just attacking one computer in a system. Owing to this, therefore, care should always be taken to ensure that networked systems are secure and are not prone to threats posed by cyber attackers. There are various things that can be done to warrant the security of a computer system as we shall discuss shortly.
The basic most network security feature that any company can adopt is what is called the user identification policy. 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 further should define the hierarchy of network users and assign different roles on each user. 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 a higher tier for super users who are responsible for auditing the system.
Passwords policy is another element of the access policy. The password policy should dictate the kind of passwords and usernames users are allowed to create. 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.

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 evaluating the business needs of an organization, an authentication software may be installed for use by the users. 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.

Also, password policies ought to limit the sharing of information to a certain degree. 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. 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.
