In this modern world where our lives and livelihoods are being put under constant threat from hackers, cyber-criminals and cyber terrorism there is a heightened need to understand the field of cyber security. Cyber crime can be defined as any criminal activity that uses computer systems and/or networks to defraud, damage, abuse, recruit or exploit other individuals. These crimes have reached epidemic proportions that are sweeping across every sector of our global economy. In order to protect yourself, your family and your business you must become knowledgeable about cyber security.
What is cyber security? The three letter acronyms CTF and TFC mean Computer network security (cyber) and computer network protection (network security). Any system that interacts with the internet is vulnerable to attack. Things such as email, instant messaging systems, chat rooms and video chat systems can all be exploited to bring unwanted cyber threats. These attacks can come from many sources such as viruses, spam, hackers, government agencies and organised criminals. Any network or computer containing one of these vulnerable elements is a potential cyber crime target.
The primary objective of cyber security is to defend against cyber attacks by preventing the penetration of confidential and protected information. The second goal is to prevent penetration of assets through physical means. This includes guarding against theft of company, customer, and employees’ confidential data through hardware and software break-ins. The third goal is to protect service providers and networked computers from malicious attackers who may be motivated by monetary gains, prestige or simply by hatred for the target organization.
A cyber attack is typically a coordinated effort between several different people, groups or even countries. It usually begins with an intention to do harm, followed by the deployment of malicious code that will perform a specific task when executed. Once the malicious code is installed, it generally seeks out pre-identified sensitive data (cyber attack) on any number of computers that are connected to the internet. These computers may be infected with spyware, adware or viruses that have infected them from the internet, or they may simply be opened via malicious software installed on the computers of web users. Regardless of how the code is executed, cyber attacks are extremely damaging to a company’s operations because they can completely shut down the server or computers of a company.
Information security also aims to prevent access to controlled information in the case of emergency situations. Computer viruses, Trojans and worms that invade a system through illegal downloading or through interaction with malicious users have been responsible for massive data losses in the past. Cybersecurity is a branch of information security that primarily deals with preventing unauthorized access to electronic data. It also tries to stop or eliminate data breaches by providing security for networks, servers, and computers that are often used in cyber attacks.
One of the major objectives of cyber security is protecting sensitive information. It does this by detecting and blocking attacks on networks that handle important information. One of the most common methods is to implement policies that require companies to screen emails to determine if they contain sensitive information. Companies are also required to put in place measures that can block phishing cyber attacks. This includes notifying subscribers and customers about phishing cyber attacks that might harm their computer systems.
Some measures to prevent cyber security threats include installing anti-virus programs on company computers and mobile devices. Companies are also encouraged to create their own email anti-spam programs and block their use in corporate networks. Companies are advised to remove potentially harmful files from their computer systems and to remove Trojans that might install themselves on company computers. Companies should also refrain from releasing proprietary information online without first protecting it from cyber criminals. Mobile devices that are commonly used by employees should also be protected from hack attacks.
Companies are advised to bolster their computer security by implementing the latest technological advances that are designed to fight off these attacks. Many cyber security professionals believe that the best way to combat these malicious attacks is through prevention. Companies should make it a habit to review their computer system periodically and to refrain from releasing proprietary information online without first securing the data with firewalls and other protective measures. These practices will help reduce the number of cyber attacks that occur and will assist with reducing the amount of compensation that victims of cyber crimes must pay their victims.
