2INFORMATION SECURITY MANAGEMENT
Introduction
The following report is all about conveyancing and real estate organization named CONVXYZ
which is based in United Kingdom. The organization is planning to set up their IT network and system.
The organization aims to provide real estate service for both property buyers and vendors(Peltier 2016).
The main notion of security system is all about preventing or reducing the business loss that is caused as
a result of possible incidents. The situation can be any one of the following like stealing information,
modification of data, deletion and destruction. It is mainly inclusive of large number of things scam
which has many victims. This particular organization comes up with a website where the client of the
organization can easily look for property details and can easily contact for estate agents (Soomro, Shah
and Ahmed 2016). After making a registration to the conveyancing service, customers can easily get the
details of the account that is username and password to the website. For this report, we are going to
use checklist method of risk assessment. This particular risk assessment methods can provide a range of
benefits like identifying security vulnerabilities, making smart purchase, improved planning and many
other.
In the coming pages of the report, a risk assessment has been done where the specification of
the owner has been discussed in details. Both kind of assets that is primary and secondary has been
discussed in brief. One threat and one vulnerability for each of asset has been discussed in brief. After
that the likelihood level of computation has been done by making used of Boston grid.
Risk assessment
Owner Specification
UK based CONVXYZ organization is focusing on to hire team by which they can set up their IT
network. The real estate organization aims to provide real estate services for both property vendors and
buyers. The service is mainly employed by different kind of lawyers. The main notion of the organization
is to reduce the overall loss which is caused due to possible incident. The main focus of authenticate
server is to authenticate the username and password for both customer and staff members (Safa et al.
2016). At the time of authenticating of task, the server needs to communicate at both end that is
database of staff and server where all the required information is stored. By the help of proper
authentication, both customers and staff can easily access the property details and present
documentation. The organization makes use of employees like lawyers, real estate agents where they
can make use of system for login into the website of the organization or even browse for internet
services (Hoffmann, Kiedrowicz and Stanik, 2016). In this organization, prior to any kind of exchange
between the buyer and vendor, buyer needs to request for money to the bank account of this real
estate organization. All the details like bank account number is provided by the help of email and post.
Asset Classification
In CONVXYZ organization, primary asset can be stated as the asset which needs to be
incorporated in the begin for importing certain kind of assets. Primary asset can state as the default kind
of scope which is needed for importing other kind of asset (Safa, and Von Solms 2016). There are certain

3INFORMATION SECURITY MANAGEMENT
number of assets that are mainly imported right after the primary assets like secondary assets. Primary
assets comprise of super set that are considered to secondary assets.
In asset system, site is known to be primary asset which is needed for various type of assets.
When the individual imports the assets for any kind then it can make use of site. It is not generally
recommended for use of site like a scope even if it is supported in case of most of the assets. The assets
in the given scenario are personal computers, web server, mail server, switch, database for staff,
authenticated server, router, firewall, internet. ISO 27005 aims to provide proper meaning to the
organization for access risk in the information security (Safa et al. 2015). The standard aims in
understanding of risk and treating it in required ways. Dealing with information risk makes use of
practical implementation and management of the given perspectives. The main notion of this standard
is all about providing proper guidelines which is needed for information risk management and promote
the general concept and idea (Almorsy, Grundy and Müller, 2016). It has been mainly designed for
assisting the overall implementation of information security depending on the approach of risk
assessment.
Threat for asset
Firewall is considered to as a part of the cybersecurity infrastructure which makes is a huge issue
for protecting the business of this organization. There are huge number of issues with respect to firewall
which can make it a bad logic for protecting the organization. The biggest threat in vulnerability is
Distributed Denial of Services attacks (Shameli-Sendi, Aghababaei-Barzegar and Cheriet, 2016). It can
mainly result in frequent attacks which is very much effective and low cost in nature. The main goal is all
defending the resources and can result in shutdown for delivering services.
Wireless access point can be considered to be immediate connectivity where the user can easily
go beyond the connectivity within the given network. Wireless attacks are mainly driven by common in
nature (Haufe et al. 2016). Wireless access point is considered to be highly insecure in nature regardless
of the kind of encryption that is being used. There are certain number of protocols that comes up with
vulnerability and can compromise with the attack framework.
Email can be considered to as one of the frequent data which is used for sending and receiving
data. But in most of the cases it is misused (Laudon, and Laudon 2016). In most of the cases, confidential
information can be easily forwarded to external target. E-mails tend to carry nasty virus of the user.
Vulnerability of asset
Vulnerability can be stated as any kind of weakness in the network in the present network which
can be exploited by a threat. At present, it is being applied in almost every area of network technology
like banking and E-commerce. The application mainly comprises of various type of network and devices
for malicious attack (Ahmad, Maynard and Shank 2015). The hackers come up with the option of
exploiting the vulnerability which can be reduced. At present, there are large number of hardware and
software tools available in protecting these kinds of attacks like firewall, Intrusion Detection System.
There are many different kinds of software available for scanning the vulnerability in the network

(Sadeghi, Wachsmann and Waidner 2015). Use of proper hardware and software does not provide
guarantee against these attacks. The only system which is secured in the one which is powered off.
Unauthorized kind of access comes into picture when the user tries to have an access to the
given resources which is not permitted at all. This particular scenario can come into picture as the
administration is completely assigned any kind of resources (Line and Albrechtsen 2016). Organization
can make use of list of department and users where some have inappropriate access to any of the
network resources. It is mainly because user is not from same department or may such one which is
outside the organization.
