Policies
Understanding Policies in Security and Data Management
Definition of Policies
- Policies are guidelines or rules set by an organisation to manage and secure their data effectively.
 - These policies act as a framework within which an organisation makes decisions regarding the protection of its data systems.
 - They define who has access to the systems, when they have access, and how they have access.
 
Importance of Policies
- Policies help in minimising risk to organisational data.
 - Policies are crucial for meeting legal and regulatory requirements related to privacy and data protection.
 - They help maintain the integrity, confidentiality, and availability of critical data.
 - Policies also ensure accountability for any breaches or losses of data.
 - They facilitate the recovery of data in case of unforeseen circumstances such as a cyber-attack.
 
Types of Policies
Acceptable Use Policy (AUP)
- An Acceptable Use Policy determines what users can do on an organisation’s network and systems.
 - AUPs usually cover aspects like social media use, the use of personal devices, and prohibitions on illegal activities.
 
Access Control Policy (ACP)
- Access Control Policies define who is allowed access to which parts of the organisation’s systems, and under what circumstances.
 - ACPs often classify users and assign them rights and responsibilities.
 
Backup and Recovery Policy
- This policy covers how frequently backups should be taken, what should be backed up, and who is responsible for executing the backups.
 - The policy also sets out a procedure for recovery in case of a loss of data.
 
Implementation and Monitoring of Policies
- Policies should be effectively communicated to all those who are subject to them.
 - Organisations should ensure regular monitoring, auditing, and enforcement of policy compliance.
 - Policies should be regularly updated in response to changing threats and organisational needs.
 - Non-compliance with policies should entail penalties.
 
Remember, as a computer scientist, you not only have to understand the structure and uses of these policies, but also consider how they can be practically implemented to satisfy an organisation’s specific needs.
