customer data and handle any potential loss of sensitive information. (YTL, 2017) Being the
victim of a ransomware attack is stressful and worrying for any business.
Ransomware is a type of malicious software from cryplovirology that threatens
to publish the victim’s data or perpetually block access to it unless a ransom
is paid. The attacker generates a key pair and places the malware.
commerce is growing at 6 percent annually, three times the growth of
traditional offline retail. Businesses are using information technology to
sense and respond to rapidly changing customer demand, reduce inventories to
the most possible levels to get to market faster. Global ecommerce and Internet

What makes information systems so essential today information systems are essential
for conducting day-to-day business in most advanced countries as will as
achieving strategic business objectives, specifically, business firms invest
heavily in information systems to achieve six strategic business objectives;
operational excellence new products, services, and business models; customer
and supplies intimacy; improved decision making; competitive advantage; and
technology (IT) consists of all the hardware and software that a firm needs to
use in order to achieve its business objectives. “Information systems” are more
complex and can be best understood by looking at them from both a technology
and a business perspective. By information we mean data that have been shaped
into a form that is meaningful and useful to human beings.
activities in an information system produce the information that organization
need to make decision, control operations, analyze problems and create new
products or services. The field of management information systems (MIS) tries
to achieve this broader information systems literacy. Let’s examine each of the
dimensions of information systems _ organizations, management, and information
technology. Information has a structure that is composed of different levels
management makes long – range strategic decisions about products and services
as well as ensures financial performance of the firm. Middle management, and
operational management are responsible for monitoring the daily activities of
the business. Computer hardware is the physical equipment used for input,
processing, and output activities in an information system.
management technology consists of the software governing the organization of
data on physical storage media. The world’s largest and most widely used
network is the Internet. Operations research focuses on mathematical techniques
for optimizing selected parameters of organizations, such as transportation,
inventory control, and transaction costs. As important part of the information
systems field is concerned with behavioral issues that arise in the development
and long _term maintenance of information systems.

online. The Internet has stimulated globalization by dramatically reducing the
costs of producing, buying, and selling goods on a global scale. New
information system trends include the emerging mobile digital platform, big
data and cloud computing.

system of an organization. A successful organization should have the following
multiple layers of security in place to protect its operation:

3. What is ransomware. Simply put, it’s
malicious software that locks down date unless a ransom is paid, hence the
name. It’s relatively new as far as malicious software goes; the first thing
you should always do is contact a security professional. Ransomware attacks can be complex and acting
without the advice of a professional could potentially cause more harm than
it’s an otherwise typical day. You wake up head into the office, pour yourself
a cup of office, and settle in to get some critical work dome before its due.
Maybe you opened on attachment that you weren’t expecting maybe you were lured
to a website that downloaded the virus. Other common ways crooks trick you into
downloading ransomware include. Imagine for a moment that you receive a phone
call from a client to hear that hundreds of their computers have been infected
with ransomware, knocking critical systems offline and putting their
organization’s entire operations at risk to your business’ revenues or reputation
as well as ensuring that you will be able to address any legal requirements as
a result of your ransomware attack. A ransomware attack creates two hard
choices for a business; either pay the ransom, or spend multiple days
recovering locked files. As an individual user, you should ensure that you’re
using a fully- updated version of windows. If you’re on an older release due to
a company policy. (Arora, 2017)
it comes to ransomware attack, what matters most is how quickly you’re able to
get back to help you identify where the ransomware attack came from and contain
it to limit the damage. You may have heard of attacks on hospitals that
rendered their entire medical suite useless, all for the hackers to get a
couple bucks and probably notoriety within a hacking community. Consider that
hospitals are probably more guarded than you. The worldwide ransomware attack
that affected banks, hospitals and other companies heightens corporate
regulatory and litigation risks, privacy attorneys told Bloomberg BNA. You have
a legal responsibility to inform them even if their personal data has not been stolen.
This type of attack is becoming increasingly common and is constantly evolving
into new, more advanced strains. Many companies are unaware of threat it poses;
however; it is important to protect your organization and your data, against
historically Microsoft office, Adobe PDF and image files have been targeted, but
MA fee predicts that additional types of files will become target as ransomware
continues to evolve. According to e scan antivirus reports 2017 India was one
of the worst affected by cyber attack. As well as having a response pain your
business should also have a comprehensive recovery plan in place. It is
generally spread using some form of social engineering; victims are tricked
into downloading an mail attachment or clicking a link. (The Business
Guide to Ransomware, 2018) Determining
the primary attack is critical to understanding what the attacker’s primary
campaign is targeting and ensures that you aren’t missing the actual attack by
focusing solely on the ransomware. Individuals with a Hotmail account can
access their email and send email from any location as long as they are
connected to the Internet.
operations which can include provisioning the customer’s desktop environment,
as well as operating data centers to host the applications. Organizations of
all types are looking to build ‘digital strategies’ or ‘digital business strategies’.
Organization such as banks, online travel agencies, tax authorities, and
electronic bookshops can be seen as IT companies given the central role of
their information systems. Ransomware can have serious implication; take
precautions sooner rather than later. Here are tips to reduce the chances of
being affected and to happen: The impact that web site administrators are
facing is twofold. Insurance attacks are generally available in both cyber and
kidnap and ransom policies.
4. Prepare a prevention and risk
mitigation plan to organizations so that the organizations are well prepared
for future attacks. General controls govern the design, security, and use of
computer programs and the security of data files in general throughout the
organization’s information technology infrastructure. Application controls are
specific controls unique to each computerized application, such as payroll or
order processing. Application controls can be classified as:
(1) Input controls
(2) Processing controls
(3) Output controls (Laudon K. C.,

not properly controlled. (Laudon K. C., 2018) Business continuity planning focuses on how the company
can restore business operations after a disaster strikes. As information

controls governing individual information systems. There are various ways to do
this. Which helps organizations identify vulnerabilities and threats to their
critical information and plan protection strategies. Any service is at least as
critical as the most important service depending on it. (Sanchez,

There is a

but also a team that will implement it. So, a key factor for success will be
the support of senior management. Organizations should not feel that every position in the response team
needs to be filled by in-house staff. The composition of the team also needs to
be regularly reviewed. Teams should adopt the model of: plan, do, check. (Preparing for future attacks, 2018)
