Despite the fact that there is a rapid occurrence of cyber-attacks in the world, it is observed that most of them usually go unreported or underreported which makes the public to develop a false conviction that they are protected and at the end it is observed that it is likely to have a devastating on the lives of people as well as to the government. Besides business and individuals being the target, key communication infrastructure is also becoming key targets for both individual and state-sponsored attackers who actually recognize the value that comes with disruption of such security systems. In this part of the paper, we are going to have a look at some of the measures which can be adopted in order to reduce such vulnerabilities that are associated with cyber-attacks (Selby & Vescent, 2017).
Some of the measures which can be taken in order to reduce any form of potential attacks on information include;
Eliminate Complexity: This is considered as one of the best moves which can be taken in order to ensure that there is the elimination of complexity which might exist in the information infrastructure. Network administrators should note is that the complexity of systems is most likely to lead to creeping of the system. Some of the reasons why complexity is as a result of poor policy management and also setting up of incomplete rules during its creation.
Visualize Vulnerabilities: System administrators should be in a position to install vulnerability scanners which can make an assessment on the severity score that is associated with a particular asset. Therefore, they should be in a position to come up with a real-time model which constantly makes an update on the security state of a given network (Selby & Vescent, 2017).

Introduction
The cyberattacks cause adverse impacts on the country’s economy, delivery of government services and the national security. Due to the nature of these impacts, the governments and other relevant authorities are in the quest to find approaches that will reduce potential vulnerabilities, protect against intrusion attempts, and better anticipate future threats. The following are the detailed explanations on how to achieve the above course.
Reducing Vulnerabilities to Cyber Attacks
Increases the use of Virtual Private Networks (VPNs): the federal governments should encourage business organizations, government institutions and other entities to use VPNs. These kinds of networks allow the encryption of information in unreadable formats (Glenn, Sterbentz, & Wright, 2016, p. 15); hence, preventing unauthorized access by the third parties. Another way of reducing vulnerability to cyber attacks is through frequent training of workforce. This act will make the targeted persons and organizations to be aware of the current tactics used to execute cyber attacks.
Protection against Intrusion
The intrusion is defined as the act of gaining access to computer systems without the required permission, (Cheng, Liu, & Yao, 2017, p. 30). There are number of ways through which the intrusion into the computer systems can be minimized. The best way to achieve this course is trough the installation of Denial of Service into computer systems. This technology is developed to detect the malicious codes and software and notify the network/security administrator, (Cheng, Liu, & Yao, 2017, p. 30). After that, necessary actions will be taken to prevent successive intrusions and unauthorized access to the computer systems.
Anticipating for Future Threats
Due to the adverse impacts posed by the cyber attacks country’s economy and security, the federal government should always be prepared for the impending threats. In this essence, the government should frequently carry out information risks assessments, (Cheng, Liu, & Yao, 2017, p. 30). These assessments will culminate to the development of the disaster recovery plans that will help the business organizations, government agencies to handle the threats posed by cyber attacks.

What goes into bound together risk the board?
The historical backdrop of data security and palliative advances returns to the 1980s when the components of border security (through firewalls and screening switches) and malware assurance (fundamentally as early antivirus advances) got accessible. After some time, as dangers developed in refinement and capacity, different components intended to verify business or authoritative systems and frameworks became accessible to counter such things. These incorporate email checks, record screening, phishing insurance, and whitelists and boycotts for IP locations and URLs.
From the mid-1990s to the primary decade of the 21st century, there was an extraordinary expansion of guide arrangements toward counter explicit sorts of dangers, for example, malware, IP-based assaults, appropriated refusal of-administration (DDoS) assaults and maverick sites with drive-by downloads. This prompted a surge of programming arrangements and equipment machines intended to counter individual classes of dangers. Sadly, an accumulation of single-center security frameworks can't resist the urge to need steady and reasonable coordination.
Oh dear, this gives no capacity to distinguish and relieve crossover assaults that may begin with a maverick URL implanted in a tweet or an email message, proceed with a drive-by download when that URL is gotten to, and truly get in progress when a clandestinely introduced keylogger collaborates with coordinated transmissions of caught information from an indirect access uploader. More terrible yet, huge numbers of these applications are electronic and use standard HTTP port addresses, so more elevated level substance and movement screening becomes important to recognize and afterward counter undesirable impacts at work.
Basically, the fundamental reason of UTM is to make ground-breaking, modified preparing PC models that can deal with, examine, and (when important) square a lot of system traffic at or close to wire speeds. Similar information that must be scanned for boycotted IP locations or URLs must be reviewed for malware marks, sealed against information spillage, and checked to ensure that conventions, applications, and information included are both permitted and benevolent. That is the reason run of the mill UTM arrangements typically group a large number capacities, including these
Intermediary administrations square uncovering subtleties of inside IP addresses on systems, and inspect correspondences and information moves at the application level.
Stateful bundle review recognizes authentic organize correspondences from suspect or realized vindictive types of correspondence.
Profound bundle examination empowers the information segment or payload of system parcels to be checked. This office secures against malware, yet additionally allows information checks to square spillage of ordered, exclusive, private or secret information crosswise over system limits. This sort of innovation is called information misfortune anticipation (DLP). DPI innovation likewise bolsters a wide range of substance separating.
Constant parcel decoding abuses uncommon equipment (which basically repeats programming programs as rapid hardware to perform complex information examination) to allow profound review at or close to network wire speeds. This gives associations a chance to apply content-level controls even to scrambled information, and to screen such information for strategy consistence, malware separating and that's only the tip of the iceberg.
Email dealing with incorporates malware identification and expulsion, spam separating, and substance checks for phishing, noxious sites, and boycotted IP locations and URLs.
Interruption discovery and blockage watches approaching traffic examples to distinguish and react to DDoS assaults, just as more nuanced and vindictive endeavors to rupture system and framework security or get unapproved access to frameworks and information.
Application control (or separating) watches applications being used – particularly electronic applications and administrations – and applies security strategy to square or starve undesirable or unapproved applications from expending system assets, or achieving unapproved access to (or move of) information.
Virtual private organize (VPN) or remote get to gadgets empower remote clients to set up secure private associations over open system joins (counting the web). Most associations use such innovations to shield system traffic from snooping while it's on the way from sender to recipient.
Current UTM gadgets join every one of these capacities and more by consolidating quick, incredible specific reason arrange hardware with broadly useful figuring offices. The custom hardware that opens system traffic to point by point and meticulous investigation and astute taking care of doesn't hinder benevolent bundles in travel. It can, notwithstanding, expel suspicious or sketchy bundles from continuous traffic streams, giving them to projects and channels. Thusly, these organizations can perform mind boggling or advanced investigation to perceive and thwart assaults, sift through undesirable or vindictive substance, counteract information spillage, and ensure that security approaches apply to all system traffic.
Bound together risk the executives suppliers
UTM gadgets for the most part appear as specific reason organize apparatuses that sit at the system limit, straddling the connections that associate inner systems to outer systems by means of fast connects to specialist co-ops or correspondence organizations.
By plan, UTM gadgets organize all parts of security approach, so they apply a steady and intelligible arrangement of balanced governance to approaching and active system traffic. Most UTM gadget makers manufacture their apparatuses to work with incorporated, online the board supports. This lets arrange the board organizations introduce, design and keep up UTM gadgets for their customers. On the other hand, concentrated IT offices can assume control over this capacity for themselves. Such a methodology guarantees, that similar checks, channels, controls and approach authorization applies to all UTM gadgets similarly, evading the holes that coordinating different dissimilar point arrangements (discrete firewalls, email apparatuses, content channels, infection checkers, etc) can uncover.
Picking the best UTM suppliers
Gartner detailed $2.18 billion in deals for the UTM showcase in 2017. It anticipates that this market should keep developing couple with generally speaking IT venture for a long time to come (rates in the 2-5% territory apply for most economies, however are higher for driving economies like the BRIC nations).
Sharp purchasers search for highlights like those depicted in the past area (modern firewalls with profound bundle examination, interruption recognition and counteractive action, application control, VPN, content separating, information misfortune/spillage insurance, malware security, etc). Nowadays, purchasers likewise search for these highlights:
Backing for refined virtualization advances (for virtual customers and servers, just as virtualized usage for UTM machines themselves)
Endpoint controls that uphold corporate security arrangements on remote gadgets and their clients
Incorporated remote controllers to merge wired and remote traffic on a similar gadget, disentangling security approach execution and requirement, and decreasing system unpredictability
At long last, progressed UTM gadgets should likewise bolster adaptable designs whose firmware can be effectively moved up to consolidate new methods for separating and location and to react to the consistently changing risk scene. UTM producers by and large work huge, continuous security groups that screen, index, and react to developing dangers as fast as would be prudent, giving admonition and direction to customer associations to maintain a strategic distance from pointless presentation to dangers and dangers.
Probably the best-known names in the processing business offer UTM answers for their clients, yet not all contributions are indistinguishable. Search for arrangements from organizations like Cisco, Netgear, SonicWall and Juniper. You're certain to discover contributions that give the best possible blend of highlights and controls, alongside size, speed, and cost qualities intended to meet your security needs without breaking your financial limit.
