1. NAC
or network access control is a networking solution. It is a set of
protocols that work with a policy of securing access to the nodes
in a network. It offers enterprise policies and their
implementation so that device control and access control can be
achieved.
- The
policies are related to resources, devices, roles, locations,
etc.
- It
plays an important role in centralized security management. In
centralized management, there are a number of terminals connected
with the center node.
- NAC
offers security checks for these terminals.
- Whenever a terminal tries to access the network, a
safety check is run on it and if anything suspicious is detected,
the access is denied.
The
best thing about this solution is that it provides flexibility in
terms of rules.
- The
enterprise administrators are allowed to define the rules and
security policies as per their understanding of the company
intranet.

2. The
role of restoration order in recovering data from
backups:
- Data
restoration helps in making copies of data to replace the damaged
or lost data. It ensures that the backup data is consistent with
the actual database at any moment. The data can be retrieved in a
few minutes and viewed on the system.
- Apart from providing relief in case data is lost
or damaged, it helps in dealing with human error as well. If a user
erases a file unknowingly, it might be very difficult to recover
that file again. However, the restoration of data provides this
utility of getting that file back.
- Restoration is not only about backup. It helps in
returning data to its initial condition.
- Malicious attacks can expose sensitive data to
hackers and everything in the organization can go wrong once the
data is tampered with. Restoration helps in retrieving the files in
multiple samples and making sure that no data is tampered
with.
