Networked systems are a major target for cyber-attacks. 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 should also define the use tiers which are based on user roles in the system. 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 policy should also spell out the password policy. The password policy should dictate the kind of passwords and usernames users are allowed to create. Since not all network users may be knowledgeable on security matters, it is crucial to help such users be aligned with the organizations expectations. Past the password policy, the organization should have systems in place that will be used to implement the policy.
The Essentials of Security - 101
Authentication software can be installed to enforce password policies. 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 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.
Why Services Aren't As Bad As You Think
The password policies should also dictate the level within which information sharing is to take place. System configurations, for example, should never be shared by internal users to people outside the scope of the business. 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.
