Data security, also known as cyber security or IT security, is the safeguarding of computer systems and networks against data leakage, misuse, or harm to their hardware, software, or electronic data, as well as interruption or misdirection of the services they provide.
The field is increasing in importance due to increased reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, along with the growth of smart devices, including smartphones, televisions, and the various devices that constitute the “Internet of things.” Since cyber security is a highly complex and controversial issue, it also represents one of the biggest challenges in the contemporary world.
Computer security threats are dangers that can cause your computer to fail. In modern society, cyber threats are escalating due to digital technology. The most damaging security flaws are:
Computer Virus Security
The computer virus is a virus that is inserted into a person’s computer without that person’s knowledge. It recursively replicates to infect files and programs on the user’s computer. The ultimate goal of a virus is to completely disable a computer and prevent it from functioning.
Computer Worm Security
Malware is a virus that copies itself from one computer to another without interaction by people. The potential risk here is that a worm can replicate at a rapid pace and in a large volume before it can be found and removed.
Individuals impersonate trustworthy individuals or businesses in a manner intended to obtain sensitive financial or personal information. Phishing has become very simple. You are lead into believing that this is real mail, and your personal information may be harvested.
Incident Response Planning
Incident response is an organized approach to addressing and managing the aftermath of a computer security incident or compromise with the goal of preventing a breach or thwarting a cyberattack. An incident that is not identified and managed at the time of intrusion often becomes more damaging when it is not dealt with immediately.
The overall objective of a security incident response plan is to minimize the impact of the incident and to reduce potential costs. Responding to compromises is critical in protecting against the exploitation of vulnerabilities. Incident response planning allows an organization to establish a response process in preparation for any possible intrusion.
A typical incident response plan contains a collection of written instructions detailing how an organization will respond to a cyber-attack. Without a documented plan in place, an organization is likely to not detect and/or respond to an intrusion, and stakeholders likely won’t understand their roles, processes and procedures.
