Setting file permissions is a form of DAC because it is the owner’s discretion. Configuring as many security layers as the user can will ensure the server will stay secure. Not all OS are 100% secure, but they can be configured to make it very hard for a hacker to
• Local cache of credentials: To provide high availability, the credentials are cached on the server that make it independent of network availability. • Multi-platform support: The products usually support applications on multi-platform. Benefits • Mitigate Threats: The critical business applications are secured by eliminating embedded passwords in applications, scripts and configuration files. By eliminating embedded passwords, both internal and external threats can be mitigated. • Ensure Business Continuity: Caching of passwords locally on servers provides High Availability and reliability to reduce the risk of downtime to applications.
These are (Virtual Private Network) VPN Policy, Password Policy and Acceptable Use Policy. Acceptable Use Policy is a policy that outlines the acceptable use of computer equipment. This policy is in place to protect employees in regards to inappropriate use. Any case of inappropriate use can expose the network to several risks, including viruses. Passwords are the frontline of protection of user accounts.
Data security is help protecting data and loss damage , and unauthorised access or modification. Data security is usually understood to availability , integrity and controlling access. Data Security generally available, honestly, and it has been revealed that access and control. Actually Data is raw form of information as columns and rows in databases or personal computers. Data security help to prevent data breaches.
Cyber Security a subset of Information Security. Cyber Security is the ability to use resources and policies to protect the use of cyberspace from cyber-attacks. Information Security on the other hand, is the protection of information that is either, printed or written, stored electronically from unauthorized access, use, or destruction in order to provide confidentiality, integrity, and availability (CIA). "The international standard, ISO/IEC 27002 (2005), defines in- formation security as the preservation of the confidentiality, integrity and availability of information (von Solms, R., & van Niekerk, J. 2013, as cited in ISO/IEC 27002, 2005, p. 1).
Cyber-attacks are attacks on a target system carried about by different people and may not be associated with a terrorist group. They may be trying to steal information or corrupt data. There are many ways to carry out cyber-attacks such as malware, botnets, viruses, denial of service (DoS) accounts and many other types of attacks. Cybersecurity is also known as information security which applies to devices such as computers, laptops, mobile devices, networks, and including the internet to include preventing unauthorized access, modify, or destroying data. Department of Homeland Security plays roles in securing the federal government and helping to secure a cyber-ecosystem by helping with investigations and arrest of cyber criminals, releasing cyber alerts about threats, and educate the public and stay safe online.
RBAC focuses not only on accessible data, but also on whom an access is granted . Role based access control enables security administrator to easily manage dynamically changing privacy rules. As the permissions are not assigned to the user directly and just inherited through the role, it simplifies such operations as adding a new user or user’s relocation in organization. Performance of composite operations is a considerable advantage of RBAC model compared to DAC and MAC models where only atomic operations are possible. For instance, RBAC enables to make a record “blood sugar level test”, enter a diagnosis, treatment, prescription etc.
P8.4. a. Preventive controls such as authentication so anyone trying accessing the system has to provide credentials and verify their identity, encryption so sensitive information cannot be accessed, and have a strong internal environment that educates employees on security measures. Detective controls such as log analysis could be used to show determine if someone is trying to log on to a system and is unsuccessful. Corrective controls such as having an effective CIRT that can access the laptop and block or delete important information so the theft cannot access the laptop.
Although the government and major companies can be deemed wrong for performing these acts, it can be argued that they are doing it for the safety of the citizens. The NSA, for example, is one of the many parties responsible for Internet monitoring.
- Reduces the risk of human error or duplication meaning that you don’t have to worry of about the risk records not being showed up. - The security is much more secure and the data is well protected as when you access the database you will have limit access to all the records and you will only be allowed to view certain records unless you have authorised access to the records.
