The disaster recovery plans for two backup systems that should be used is a internal backup and a
external cloud based backup a alternate plan could be to create a backup servicer at a less comprised
location to sever as a backup pin the event of a disaster. The tools I suggest to be used for the backup
services I recommend is download and install method and a web based backup service. For the download
and install backup method requires a backup sever to install the files to it grant temporary access via
online to a backup sever the interface usually allows the user to select what files are selected to be backed
up this also works in the reverse you can download selected files from the remote sever to the work
computer or a approved secure device. The web based backup services that I suggest to use would be
dropbox or onedrive web sites that are good for cloud back up this services this option provides
employees to access the files and data from a web site if the office or sever goes down due to natural
disaster or malicious bugs compromising the server give remote access without the expense of your own
separate sever still cost but will be less it also easy for user to install as well as the responsibility for the
safe transit of data is outsourced making even a even easier user interface it also provides a quick
recovery of data also portable they are set up with reminds of when data wil happen as well as what’s
included both sites have a similar interfaces making it easy for users and employers. They each come with
15 gb free backup service similar priced as well make it more of a preference to which is better.
Backup
management is largely considered to be an IT department's responsibility. Companies that lack the
resources or specific skills required to perform and manage backups outsource the responsibilities to
managed service providers (MSPs) but someone should be designated to ensure the correctly set up
backup data systems and double check Vidal data is backup. There are a few options on how often to
backup the system are a full backup which is a compressive backup the down side to this you may be able
to customize what is backed up it dose require a lot a space also it has to backup more frequently i.e every
day is suggest for this kind of backup. Incremental backup requires a full backup first to have a base for
changes made to each individual packet of data this method should be backed up based on how much and
how often the data is changed but the blanket suggestion for the time between backups is a week so at the
end of each week. The data to be protected at rest is important to achieve this there should be a few things
being used first a firewall to block access to unauthorized user as well as encryption if the firewall false
that way they can not read what they got also data that isn’t in use or accessed frequently should be
archived and password protected and encrypted or tokenized. Tokenization refers to taking piece of
sensitive data, such as a credit card number, is replaced by a surrogate value known as a token. The
sensitive data still generally needs to be stored securely at one centralized location for reference and
requires strong protections around it. So to simplify the process of issuing a digital representation of an
asset on a blockchain. The time it takes to get the primary database takes to get back to full operations
depends on the severity of the disaster and how well the risk management plan has planned for and what
measures for instance if a flood happened and wiped the servers out that will take a much longer time due
to having to reconstruct the sever versus a power outage which will be a brief shutdown these things can
be minimized by having a backup hot site which is a replacement of the sever same thing just on back up
for emergencies temporary service can be done with warm and cold sites as well allowing employees to
work at home via backup sites running the sever from the cloud backup. For communication until full
services are restored employees should use secure email and approved instant messenger employees
should not use phones due to the lack of protection even if they are temporarily made part of the dmz they
are still vulnerable this also is a very vulnerable time for social engineering due to the confusion and
disruption of services so I think a reminder course for employees to reintroduce them to the concepts of
social engineering and the best practices on how to avoid being tricked by malicious parties.
So my suggestion is a differential backup system with a weekly updates as well as a website backup for
quick access. It is my opinion that a backup sever site (hot site) should be set up if budget supports this it
is the quickest way back to work. Also, a warm site should be held in reserves to help business to resume
as fast as possible. All data at rest should be encrypted and archived if not often used but just encryption
should be used for all data and communication can be safe and secure there should be a firewall installed
if a web based services with its own protections to prevent unauthorized entry or monitoring. I would
suggest The Advanced Encryption Standard (AES) this has the largest bits available for usage this method
is consider the industries best encryption safe from most attacks excepts brute force. Hasting should also
be used for verification of the data and sender. A risk management plan would be more effective to create
a disaster recovery plan knowing what issues the sever may face well help keep it better protected the
plan I have laid out is a simple non inclusive general set up for a network and backup most of the
planning is based on the chances of what could happen and what is most likely to happen. This week lab
on image backup was a good practices run on how to get stared on learning a ways to backup data safely.
