What Is Cyber Security?
What is cyber security? Computer security, or cybersecurity or information security is the safety protection of networks and computer systems from data loss, access to or damage to their computers, software or hardware, and from the interruption or misuse of the services that they offer. It is necessary to protect sensitive information (whether by theft, mis-sold, installed, or otherwise) or to ensure that network systems remain operational. Cybersecurity professionals are involved in creating, monitoring, and operating the entire computer system security and safety lifecycle – from the early stages of development through the gradual deterioration of a given system. It also involves the detection and avoidance of vulnerabilities in networks before these systems are made accessible to the public or to other threats.
There are three types of cyber threats: malware, exploits, and scripts. Malware and exploits are designed to cause immediate damage, either via the mis-installation of an actual application or the automatic transmission of viruses, Trojans, worms, and other code that can penetrate and damage a system. While most attacks occur from attackers using advanced and sophisticated tools, there are still some basic attacks that can occur from web exploits – for instance, if a hacker gets into your website’s HTML code. Both malware and exploits are categorized according to their characteristics and methods of operation.
A growing problem for many computer systems across the globe is known as malware. Malware programs are typically created and spread by hackers looking to gain unauthorized access to a computer system. These can include virus-based infections such as viruses, Trojans, worms, and malware that are designed to compromise a system by corrupting programs, damaging files, or redirecting Internet traffic. Some malware can work in a silent fashion without any noticeable changes to computer systems, while others make life harder for the user by slowing or disabling software.
Some of these cyber attacks have resulted in what is known as “cybersecurity incidents” – incidents in which a computer system was compromised and infected with malware, leading to the spread of that specific type of attack. For instance, a group of hackers might create a worm that installs itself on a victim’s machine and then proceeds to delete important files, render a system useless, or steal sensitive personal data. Other cyber security incidents result in a more visible impact: hackers may create a vulnerability in a piece of software applications, and then attempt to exploit that vulnerability for profit.
One of the most common cyber security threats faced by businesses today is a data breach. In this scenario, malicious actors obtain a user database or a system file that contains sensitive data. They use this stolen information to perform unauthorized functions on the victim’s computer. From straightforward data theft to financial fraud, the objective of cyber attacks is to use this information in ways that would damage a business or cause it to experience financial ruin. Unfortunately, because these threats often do not come to the attention of the public or the proper authorities, the numbers of these cases are likely under-reported.
Because of this very reason, it is essential for organizations to have in place an effective data security policy. The primary goal of this policy is to detect, prevent, and respond to all forms of threats. However, organizations must also have a process in place for addressing the different types of attacks that they may face. For instance, a company that experiences data security threats can expect their network to be compromised by a wide range of attacks, including denial of service attacks and tampering with system files. These types of attacks can not only cause chaos for the users of the network, but they may also sabotage confidential business information.
Not all types of attacks cause immediate damage to a network. They sometimes simply slow down operations. In some cases, they cause a series of errors that appear to come from legitimate system errors, but are in fact a hacker’s attempt to infiltrate your network. At other times, the hackers may temporarily deny access to data files or deny the system permission to make changes to the system memory. In rare cases, they may even be able to gain access to system memory and execute commands.
One of the most common forms of attacks is known as a “malware attack.” Malware attacks compromise a computer’s operating system through a virus or other type of malware, causing it to function improperly. The malware may actually work by changing a few file configurations, making the computer extremely vulnerable to further attacks. Most of these viruses originate from other websites on the internet and send out phishing emails that appear to be coming from legitimate companies. These emails usually include a download link that requires users to click in order to gain access to a particular piece of software. Once the unsuspecting victim clicks the link, the hackers may gain access to important company data files and other valuable company information.
