INTRODUCTION
In today’s world it is very difficult to identify malicious attacks or vulnerability that can
cause harm so systems. These attacks can even harm complex distributed systems. Any damage
done by it will lead to failure of overall network. thus, it is very essential to control and defend
systems from vulnerabilities (Azar and Vaidyanathan, 2015). This report will describe three
distributed systems and various methods to defend it from attacks. Also, it will compare
similarity and differences between them.
Three distributed complex system
Telecommunication – it is a system which is used for connecting mobile, computer and internet
network. Usually, they are connected with a centralized server. it is a very complex system as
electrical waves are sent and received.
Banking – there is a centralized banking system which are used by large banks to perform their
operations. This system is highly secured as it contains data of large sets.
Internet – In modern world internet has emerged as highly complexed and advance distributed
computer system. Here, example can be taken is Google (Ruths and Ruths, 2014). It is a search
engine that consists of millions of website and webpages.
How well each system defend attack
1) the systems are protected with several types of security layer. The sever is secured with
advance protocols and allows user to interact with outside system. In case of any attack
immediate action is taken.
2) these systems are secured with high security measures and protocols. In this updated software
and applications are installed to defend it from attacks.
3) Google is highly protected from attacks. They are having their own security infrastructure and
protocols through which systems are defended. Besides this, it they have establish server in
different countries which are connected to each other.
Vulnerabilities of system- The above systems can suffer attack from different sources. It can
damage the entire network and can lead to loss of data. there are several types of vulnerabilities
that can occur. These are as follows :-
Modeling – It means flaws in internal controls, security procedure, etc. resulting in security
breaches. It can be categorized in two that is information and operational (Friedkin, 2015). It
affects system by causing data loss. Society is affected as the personal data of people is steal.

Fraud- it refers to deception of practice in order to secure unlawful gain. Here, confidential data
and information is sold to companies. A fraud can be divided into two that is swindlers and
impersonators. The outcome of fraud to system will be improper security of data. entire system
has to designed to secure data. society will be affected as well as personal data is leaked.
Vulnerability research issues – this means that flaw in design, implementation or deployment
of system. The outcome of breach to system will that overall infrastructure has to be redesign
resulting in failure. It affects society as services will be interrupted.
Among fortune 500, AT&T belongs to telecommunication sector. So, they are having
system where all data is stored. They company can suffer from vulnerability of modeling. It can
damage their system and lead to data loss (Von Meier and et.al., 2014). Thus, to protect it
company must update their security software and applications. The data must be back up
frequently so in case of loss it can be retrieved. Moreover, any malicious activities or fraud must
be recognized quickly.

CONCLUSION
It can be concluded that distributed systems process large sets. It is very crucial to design
and implement security measures so that vulnerabilities can be defended. Each system has their
own method of defending attacks. There are different types of attack such as modeling, fraud,
etc. that can result in data loss, interruptions, etc.
