ITC596 IT Risk Management | Wireless and Mobile Communication

Before wireless communication, wired technology is used but the main drawback of wired technology is that it cannot be used for long-distance communication. After that wireless technology developed and this technology reduced all drawbacks of wired technology. Many mobile communities use the technology for communication purpose and it is observed that in 2020 around 80% of people will use this technology for communication purpose because it changed the way of communication. This progressive technology delivers a stage where operators can transfer and obtains data or information from one site to another. This skill is utilized in many governments, businesses, and in banking sectors0 for transmission of material from one individual to another. In this contemporary generation, the proportion of wireless communication is growing quickly because this technology delivers better facilities and also increases overall efficiency.

Advantages of wireless mobile communication

There are many benefits of this technology which are following

• More efficient
• Flexible
• Easy to use
• Reduced power consumption
• Low cost
• Increase productivity (Osseiran, Boccardi, Braun, Kusume, Marsch, Maternia, & Tullberg, 2014).

Drawbacks of wireless mobile communication

• Slow in speed
• Less secure
• Increases many security
• Complex to assemble
• Maintenance cost is very high (Medbo, Börner, Haneda, Hovinen, Imai, Järvelainen, & Kyösti, 2014).

Recommendation

This advanced technology improved overall efficiency but there are few IT risks and threats occur in this technology such as loss of data, less secure, reduce speed and increase many security risks. These all are the main drawbacks of this technology but many people use this technology because it is very flexible and low-cost technology. This problem can be reduced if mobile organizations increase security system in communication and use encryption method for data transmission Because encryption method is one of the simplest methods to increase securities of your data in which data or information converted into particular code when data is transmitted through transmitter and at receiver this code again converted into original information. Users and employees can use security systems and a backup system like cloud computing to reduce security risks. This is a wireless process and it can be easily hacked which is one of the biggest problems of this technology. There are many hackers that use online servers to hack your data or information and it can be reduced by increasing the security system, using data backup plans, and through encryption method.

Cyber attacks

Cyber attack is defined as an offensive maneuver which blocks computer systems, network systems, and personal devices. It is one of the most common problems for all organizations and communities because it encrypts data or information file in your computer systems (Rid, & Buchanan, 2015). The problem of cyber attack is increased rapidly in last few years and in 2017 WannaCry ransomware is one of the biggest cyber attack in which around one thousand computer systems were hacked and demand money to restore data or information. There are many types of cyber attacks which are following

• Phishing Attacks
• Cross-Site Scripting (XSS)
• Man-in-the-Middle (MITM) Attacks
• SQL Injection Attacks (SQLi)
• Denial-of-Service Attacks
• Ransomware attacks
• Spear Phishing Attacks
• Malware Attacks

Working process of cyber attacks

Cyber attack is the biggest problem in all countries and in which there are mainly three types of cyber attacks observed which are very harmful such as malware, ransomware, and phishing attacks. They communicate through e-mail or message and user click on fraud links through which hacker enter in human-computer systems and encrypt all personal files and block your computer systems. After that, they communicate with you through online websites and demand money to restore data or information. This problem increase by spam and fraud e-mails and messages and users read message after that hacker hack all details stores in your computer systems (Liu, Wei, Song, Liu, 2016).

Threats and risks of cyber attacks

There are many threats and risks occur due to cyber attacks such as social engineered Trojans, phishing, advanced persistent threats, unpatched software, network traveling worms, its impact on children and adults, loss your data or information and produce financial problems. Therefore it is one biggest problem for al IT management systems because many hackers blocked data or information file and also locked your computer systems and after that, they demand money to restore data files. Ransomware uses an algorithm process to block computer systems by sending e-mails and messages (Pan, Morris, & Adhikari, 2015).

Recommendations

A Cyberattack is defined as a risk factor for human-computer systems and networks which use malicious algorithm to block computer systems and encrypt your data files. This problem can be reduced by using various security systems and managers in an organization should provide proper training for this type of problem. There are main two processes can be used to reduce this type of problems such as use backup plan like cloud computing technology and robust filtering process. Robust filtering is used to block spam messages and e-mails and also remove fraud messages through which this problem can be resolved because hackers communicate with people by e-mail and messages and people should use backup systems in this type of situation (Isozaki, Yoshizawa, Fujimoto, Ishii, Ono, Onoda, & Hayashi, 2016).
