Today’s Cyber Security Threats to the Financial Sector

This article explains the security and privacy issues related to mobile cloud computing in the finance sector.  I find that this article illustrates the security and privacy issues related to mobile computing in the finance sector that is why I chose this article. There are several issues and challenges associated with mobile computing. The data breach is one of the concerns that must be taken care of. Mobile banking is carried out on the cloud platform. The financial data stored in cloud database can get lost due to the security and the privacy breaches. The unencrypted data can lead to virus attack.  The intruders encrypt those data and use them for their benefits. Us et al. (2018) state that the hackers can get to know the financial data of the organization through a mobile cloud platform. Any organization’s confidential data can get affected by a mobile cloud platform. The organization can lose the data due to the malware attack and the virus attack. The intruders can hack the information for their benefits. The organization can face severe loss as a result of a security breach. Us et al. (2018) state that the unprotected third-party services can access confidential financial data of the organization can steal and modify those financial data. The intruders can evade through the insecure system, and the database can steal the customers’ data as well. The hackers do not delete the customers’ data usually. They use the customers’ data for later use. Mobile banking becomes popular in recent times. However, the security of the mobile devices is still a matter of concern. The hackers having skills and expertise can find out the security loopholes in the mobile devices. The customers’ bank details can be compromised, and their hard earned money will get robbed off. In this way, the customers’ privacy can get threatened due to the hackers’ attack.  Secured platform configuration can help organizations to conduct mobile banking over the cloud platform securely. I find this article very useful as it details the security and privacy concerns related to mobile banking in the finance sector.

Task TCP/IP is consists of communication protocols used to transfer packets between computer hosts within the network. In TCP/IP, the transport layer is responsible for providing the application layer with session and datagram communication services. Discuss the common standards at the transport layer.

Difference between TCP and UDP Protocol

The article describes the transport layer standards in details. I find this article quite descriptive. The article explains TCP and UDP in details. In TCP/IP protocol suite the two main standards and protocols are TCP and UDP. TCP stands for Transport Layer Protocol whereas UDP stands for User Datagram Protocol. TCP is connection-oriented. A connection gets established between server and client before transmission of data. The control messages are exchanged between server and client (Javarevisited.blogspot.in. 2018). TCP provides greater reliability that means TCP guarantees data transmission. The data can get recovered if the data gets lost during transit. TCP also ensures that the data will be sent to the receiver in the order the sender sends the data. TCP does ordering and sequencing. TCP suits those applications that require delivery sequentially. Here, the data is transmitted as a byte stream. TCP is relatively slow as it establishes a connection between the sender and receiver. Also, it guarantees secure order delivery. The header size of TCP is about 20 bytes. The examples of the TCP protocols are the HTTP and HTTPS. UDP is connectionless protocol (Javarevisited.blogspot.in. 2018). UDP connection is suitable for multicast distribution of the message. The connection is unreliable, and it does not provide a delivery guarantee. Also, UDP does not provide any sequencing guarantee. In case of UDP, the packets are transmitted individually, and after that, they are checked for integrity. UDP is relatively fast compared to TCP. The header size of UDP is 8 bytes. Examples of UDP are DHCP, NFS, DNS, TFTP, and BOOTP. This article helps me a lot in understanding the transport layer standards in details.

Task The Internet of Things (IoT) is a system of interrelated computing devices that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. Discuss the cybersecurity challenges faced by the health sector in this IoT era.

Cyber Security Threats in Health Sector

The article describes the ill effects that occur if cyberattack occurs within the system of the health sector. I find this article quite informative about the cybersecurity challenges that are faced by health sector in IoT era. There are several cybersecurity threats associated with the health sector. The hospital information system can get seriously affected due to the virus and the malware attack (Cyber Security Threats in Health Sector 2018). The ransomware is another threat which is a matter of concern. The intruders encrypt the files within the database and ask for money. If the hospital management staff pays the money, then the intruders decrypt the file back. Denial of Service attack is another form of malicious attack that can attack the health sectors. The intruders attack the insecure network and make the entire system vulnerable (Cyber Security Threats in Health Sector 2018). The intruders then attack the compromised system and steal all the vital information of the employees and the patients. The employees of the companies do not set a password. The employees also set a weak password which can be guessed very easily. The hackers take this opportunity and attack the system and take away the vital information of the employees. For this reason, the privacy and the security can get compromised. The employees must set up a strong password, and they must create a two-step verification procedure. However, they do not use this procedure and fall into the trap. IoT devices are used now in the health sector. The IoT thermo-meter device is capable of sending data to the phone or stethoscope; this IoT thermometer can record the breathing sound of the patients and can store them on the server (Cyber Security Threats in Health Sector 2018). The security flaws or any kinds of security breaches can provide faulty data. Thus the doctors face immense difficulties to diagnose the patients’ illness if the hackers attack the IoT devices of the health sector. I find this article explaining the threats that can adversely affect the health sector.

I have chosen this article as the article contains all the relevant security information about Social Network Service (SNS), this article explains the security risks that can occur. The article also elaborates the mitigation procedures by which the security risks can be handled efficiently (Hootsuite Social Media Management. 2018). The policies vary from organization to organization. However, the security guidelines, the safety guidelines are somewhat for the organization. The policies can help the users and the customers to safeguard their system and database from the threats and the security issues. The customers must follow the guidelines; they must use a secure password, the customers must know how to avoid spams, phishing attacks. They must know how to fight against the malware attacks and the malicious software attacks.  In case of business activity, the organizations must train their employees about the social network threats; the employees should have a clear idea about what they should do and what they should not do. The employees should be trained to identify the security risks (Hootsuite Social Media Management. 2018). The security risks can help the employees in knowing the malware and virus attack beforehand. They can even get to know the about the malware attack and can provide solutions to mitigate the risks. The organizations should give responsibility to certain individuals, and the individuals should fight against those threats. The organization must adopt certain software to safeguard their system and the database. The LastPass software can safeguard passwords. The popular antivirus software like Kaspersky can help to prevent scams, malware, and viruses. I have chosen this article. This article elaborates how the system can be secured following the suitable guidelines and policies.

Big Data Challenges and How to Overcome Them

The article explains the big data challenges in details. The challenges they suffer challenges typically related to infrastructure, applications, skills, attitudes, fragmentation, and valuation. I find this article quite helpful in knowing the challenges associated with big data. According to Team (2018), the organization deals with the technical structure, storage, bandwidth, and CPU. The organizations are not aware how much resources are required for them to conduct the business activities. The big data and the cloud technology can help them to scale up the business activities. Again, the organizations trying to adopt the big data technology are not used to the technology. The existing resources may not be compatible with the big data. They will have to learn several aspects of the big data and must train their employees the same. The organizations will have to hire a business analyst. The business analyst who has the required knowledge and the experts will analyze with the help of the statistical algorithms. It is a challenge for the organizations to find out the appropriate business analyst. The organizational data are mostly fragmented. In an organization, there are numerous departments. Every department handles different kinds of data. Team (2018) illustrates about the fragmentation, and the issues associated with fragmentation have been detailed in the report. Team (2018) explains that the big data adaptation can be a challenge for the organizations as the organizations will have to integrate all the services. Thus big data adaptation can affect the organizations economically. Moreover, the organizations will require a lot of time to adopt the big data technology fully; they can face loss economically. They can lose the customer base. I find this article very useful as it explains all the socio-economic issues and challenges associated with big data.

The project management team following the agile methodologies. They must work according to the DO-178B, ISO 26262 and ISO 62304. They must work according to the compliance of those standards. The management team adopting the agile methodology can mitigate the issues that get aroused. The team requires relatively less end-to-end overhead (Ibm.com. 2018). Following the agile methodology, the project team can get less rework, and the project can complete the task within the stipulated deadline. The project team can find out that their project has not worked appropriately. The clients are found to be not satisfied with the project. The agile methodology can help the organizations to work effectively (Ibm.com. 2018). The organizations must submit partial to the clients and should verify it from the customers’ end. The clients must provide feedback to the organizations back, if the feedback is fine the organizations should work on the rest, in this way they can give their best to the clients. The agile and lean methodology give priority to the project activities that involve high risks, that is why the risks can be analyzed and can be mitigated within the short period using the agile methodology (Ibm.com. 2018). Multiple ways can mitigate the high risks, and the agile project management allows parallel risk management where project management team can get multiple best solutions. The organizations following all the approaches can choose the one that suits them best. The agile and lean practice can enhance the productivity profile. I find this article very useful (Ibm.com. 2018). The article will help to acknowledge the benefits that agile and lean practices can enhance the project activities and can make the activities agile and effective.
