Overwhelmed by the Complexity of Security? This May Help

Basics of Computer Network Security

The main target for cyber-attacks today is the networked systems. This is mainly because of the fact that attackers know that once they gain access to one system, they are sure to affect the entire system. As a result of this, therefore, it is paramount that networked systems are maintained on a secure platform so that no attacks are able to be successful on it. There are various things that can be done to warrant the security of a computer system as we shall discuss shortly.

User identification policy is the most important step that can be taken to guarantee the security of any networked system. 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. The top of the hierarchy should always have the admins whose main roles are to modify existing users and adding new users to the network. Additionally, admins can have super users above them whose main role is to run audits on the network systems as well as to approve roles that are above the administrative users.

The network access policy ought also to define the password policy. This policy defines the nature of login credentials users can use to access the systems. Since not all network users may be knowledgeable on security matters, it is crucial to help such users be aligned with the organizations expectations. 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.
What Research About Products Can Teach You

Enforcing password policy can be done by use of third party authentication software. Today many organizations are available whose main concern is to offer authentication software to companies using network systems. Based on the needs of an organization, the right software may be sought. The software should be able to cater for as many password matrixes as possible to allow the users create passwords that are unique and hard for unauthorized users to guess.
The Essentials of Security – Revisited

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. Other information that can also be included in the policy can be things like the validity of your login credentials, the permitted duration of use for the password as well as the measures to be taken against offenders of the police.
