Essay Example on Data Security: Essential Ideas, Reactions, Regulations & Reclaiming

Introduction

Essential ideas and procedures for data security on the internet include episode reaction, detailing, regulation, and reclamation of the data foundation. This course included weekly in-depth research postings, writing research papers (or exams), and conducting lab experiments on (1.0) threats, attacks, and vulnerabilities. This included analyzing indicators of compromise and detecting the responsible type of malware, including crypto-malware, ransom ware, worms, Trojans, and viruses. Crypto malware is compromise programs that can mine data illegally, crypto-mining, designed such that it can perform this data mining completely undetectable. Ransom ware illegally encrypts data mostly from organizations such that files and databases cannot be accessed, and a ransom becomes the key to decrypting the data. Worms are standalone malware that primarily use a computer as a host to spread themselves and can delete or inject data on a computer system. Trojans are viruses often disguised as legitimate programs and software, primarily used by hackers to get easy access into systems and databases. A virus is a malicious program or line of code written with the intent of altering the normal functioning of a computer system. Viruses can spread from one host infecting different systems via files and shared programs. When these threats affect the intended operation, then it is said that the system is attacked. Social engineered attacks use psychological manipulation of human beings. It can happen through baiting, phishing, or pretexting an individual to give up crucial information on data. Another conventional attack is wireless attacks, where vulnerability on a system is exposed when a computer is connected to public Wi-Fi. There is more open access to default SSIDs and passwords. It is essential to categorize the threat's type and attributes to understand the attacks launched on a cyber-system. The risks can be grouped into hackers, who primarily need to manipulate and control systems, organized crime syndicates, and competitors trying to gain competitive advantage by in-house mining data. All orders need to undergo a simulated attack that is aimed at exposing vulnerabilities and missing links to prevent attacks. The tests are referred to as Penetration tests. Vulnerabilities can also be detected by vulnerability scanning concepts such as Nessus, which audits systems remotely to expose weaknesses and Security Administrator's Network Tool for Analyzing Networks.
