NETWORK SECURITY MANAGEMENT 3
1.0 Introduction
Network security involves both the software and the hardware technologies whereby it is
any activity that has been designed for the protection of the integrity and the usability of one's
data and network. It is the security that is provided to any given network from access that is
unauthorized. Many companies systems that are involved in communications and transactions
that are regular in nature across the globe are vulnerable to cyber-attacks encouraging cyber-
attacker to access data, programs and even systems in an authorized manner. The complexity of
network architecture is seriously being faced by cyber-attackers who are always out to exploit
any available vulnerability (Abomhara, 2015). This has risen an alarm to many government
organizations, businesses and even individual to improve their security so as to protect their
systems from cybercrime or network insecurity. There are many management programs with
policies and its procedures that are put in place to help mitigate network insecurity from thriving
further and spreading in networks. These measures need to be put in place and action to avoid
any form of downtime that can cause a lot of damage and disruption and tarnish the
organization’s reputation.
2.0 Cyber security landscape/ threats
2.1 Internet of Things (IoT) device threats
The cyber security landscape is very dynamic and hackers are constantly looking for
vulnerabilities to exploit in networks that are corporate; meaning that the days of just building a
wall that is defensive to surround a corporate are long gone and something more advanced and
trending is needed for network defense. There are so many Cyber security threats that need
immediate actions of mitigation. For example, the IoT devices threats, whereby many company
networks are adding several solutions like, cameras to monitor security and make maintenance

the last consideration. Without managing, implementing and updating process of the network,
the IoT device will be vulnerable to cyber-attacks.
2.2 Crypto-jacking and Mobile Malware
Crypto-jacking is another threat to network security. This has been accelerated by the
absence of network segmentation and even backups. One of the biggest threats is the ransom
ware that badly affects the businesses network. It is believed beyond a reasonable doubt that
actors of the threat are employing the previously used ransom ware for data encryption to ransom
resources on the network or even to mine crypto currency. Form the standpoint we can visualize
a great threat that is encouraged by the appliances systems and other resources that can easily be
used to mine crypto currency (Caldwell, 2018). Another cyber security threat is mobile malware.
This is mainly because devices that are associated with mobility are an attack target. Many
organizations that adopt and use the mobile device management have discovered that the
concerns about privacy have limited adoption of their devices hence they end up ignoring this
privacy aspect making any of these devices in the network vulnerable to attacks from
cybercriminals. The old version of some of the mobile devices such as the Android devices
which is quite challenging to get them to control and support those devices since it is still
pointing back to issues of mobiles. This is a threat to an individual and even an organization
network.
2.3 Cross-site Scripting threat
Cross-site scripting is another thing that threatens the security of our networks. This is the
leading type of vulnerability that permit adversaries to make use of an organization or business
website for the execution of codes which are untrusted in the browser of the targeted victim
(Fang et al., 2018). This makes it even easier for the cyber-attackers to make an interaction with
