There are three types of cloud storage, namely public, private and hybrid. These all have the advantage of advanced firewalls, intrusion detection, and encryption.

IT Security Risk Management:


It is a process of managing the risks of everything which is associated with the use of information technology and network. The process involves identifying, accessing and treating the possible risks of Information technology.

The basic role of the overall process is to treat risks by an organisation’s total risk tolerance. There are different stages of the ISRM, which include Identify assets, Identify vulnerabilities, Identify threats, and to identify controls.

After the risk to a company has been identified, then they need to select the method of treatment that they can use to reduce the risk of any harm from external sources:-

1) Remediation: It means implementing control that can reduce the risk of data loss.

2) Mitigation: Limiting the likelihood or impact of the risk but not wholly terminating it.

3) Transference: This involves the transferring of the risk to another entity so that your organisation can recover from the loss of chance.

4) Risk acceptance: This process involves not fixing the risk but to accept the risk as the cost of the loss is less as compared to the cost of repairing it.

5) Risk avoidance: This IT services treatment involves removing any exposure to an identified risk.
