SYSTEMS DOCUMENTATION AND INTERNAL CONTROLS
Internal Control Weaknesses There is no physical counting of the
inventory items.
Impact These Weaknesses If the items are not kept a track of then if
something gets lost then it will not be found
Specific Internal Controls Tagging the items in the inventory and then
keeping a track of the location the item was
last stored can help in the tracking of the
lost items. Also keeping an active
connective closed circuit camera would help
in looking after the warehouse floor (Sittig&
Singh, 2016).
There are many small internal weaknesses which is organization is facing in the due
source of time. The factor of allowing the customer to buy goods on credit basis was one of
the major factors concerned in the factor, this issue directly decreased the factor of profit. The
use of dock for the incoming and the outgoing delivery of the item can be indicated as the
second point of emphasis, this related to problem creation within the operation of the
organization. In any organization the database in order to keep the record of the customers
plays a vital role , the company lags behind in this field (Kharraz et al., 2015).
Impact of the weakness
The factors of the weakness have a varied impact on the organization. Putting
emphasis on the sales operation team, the policy of the company to provide goods to the
customer on a trail period of 30 days hampered the overall working of the team.

Overview of the Ransom ware attack
The main factor which caused the problem was a self-replicating software piece that
mainly took advantage of the different vulnerabilities with the main focus on older versions
of Microsoft windows. Finding an exposed target, it spreads from system to system. the
attack of the ransom ware resulted in demand of ransom which varied from an amount of
$US300 and it mainly accompanied increase in amount on an hourly basis. The security holes
where disclosed several weeks after by the shadow brokers, this group was a mysterious
group that mainly published different hacking tools which was used by the NSA (Collier,
2017). Right after the discloser the Microsoft company issued software’s which mainly
included the patches which was made for the loop holes. On the other hand, it can also be
stated that many companies did bot install the patches or used older versions of the operating
system which did not support the patches which was oriented to protect the system
(Mohurle&Patil, 2017).
The most disruptive kind of attack was targeted towards the clinics and the hospital
which were in Britain. The case forced to turn away patients after the access of the computer
system was not allowed due to the attack. There were many other countries which were
involved in the attack for example Spain, Russia, Portugal. Cyber extortionist mainly ticked
the victims in order to open malicious attachment which had the malware in order to spam
emails that mainly appear to be contained in job offers, invoices, warning which are related to
security and other files of legitimate.

related to the problem is that is the company Motherboard and Pvt Ltd faces problem with the
tracking of the goods in their warehouse. The items have been tagged and kept in the shelf.

(RFID). This would help in knowing the location of the product and if an unauthorized way
