What is cyber security? Computer security, or cyber security or information security is the overall protection of networks and computer systems from the attack or manipulation of external sources, including viruses, malware, spyware, or keyloggers, and from the unintentional destruction or damage of their hardware, software or other electronic data. Cyber security also encompasses the physical protection of a network, consisting of firewalls, intrusion detection devices, and physical security measures. One type of cyber security is application security, which seeks to stop an attacker from getting access to a program or service that he or she would use to gain access to your system. Another is network security, which is meant to protect against attacks on one or more networks.
An important element in maintaining cyber security is an awareness of the latest threats, which can be updated through annual surveys that companies conducting business online must conduct. These include definitions for several words commonly used to describe Internet-related activities. The most common terms are viruses, malware, spyware, and hackers. According to experts in this field, some of these terms may not be defined as fully as they should be because many of them are reactive types of threats, which means they are created by humans and not by a single factor.
For instance, it is true that viruses are a form of cyber crime, but it is not the only form. There are many ways in which attackers make their viruses, such as extracting or rewriting files, disabling programs, and sending emails with a infected attachment. It is possible for an Internet user to open an email without realizing that it contains a virus or worm. It is also possible for an attacker to create a Trojan horse and use it to send secret information across the Internet.
The other type of cyber threats is done through information security. This includes stealing information, fraud, and hacking. In information security, there is always the possibility of a person gaining unauthorized access to a company’s system, software program, database, or even the network of a company’s internal computer network. When people lose information due to cyber attacks, they could face serious legal troubles.
Aside from causing legal problems, information security also can damage a company’s reputation and affect the performance of its business. Therefore, companies must put in place protective measures in order to minimize the impact of cyber attacks. The best way to secure a company’s data is to invest in high quality and highly reliable computer systems that incorporate security measures. A business can also take measures to minimize the impact of a cyber attack by educating all employees on the importance of using security measures and by making them familiar with the basics of network security. Companies can also take measures to protect themselves when the need arises. Common measures included in information security are firewalls, anti-viruses, and anti-spam programs.
Another aspect of information security is performing what is called response management. Response management is the management of a company’s response to malicious attacks or vulnerabilities found in its network or computer systems. It involves the quick adoption of measures that will mitigate and defend a company against these types of attacks. For instance, if a large percentage of a company’s network is infected with a virus, the company must be ready to respond to the attack immediately and organize its workers to deploy network security measures in order to halt the spread of the virus. Companies should also have contingency plans for an attack on their computer networks. It is important for companies to understand the threats they face and develop appropriate response plans for fighting these attacks.
Another aspect of cyber security that companies need to address is application security. Application security refers to the identification, prevention, and correction of security vulnerabilities of network-related applications. Through application security, a company can reduce the threat to its sensitive data. By developing strong passwords, monitoring network activity, and scanning application software for security weaknesses, companies can greatly reduce the amount of time users spend entering secure areas of their networks. Moreover, through application security companies can strengthen their defenses against what is known as man-in-the-middle attacks, where hackers get hold of personal information that users enter into a program or web server.
Overall, what is cyber security means knowing what risks your company faces and taking preventive measures to minimize those risks. These are essential elements of a sound cyber security plan. Companies that do not take steps to address these threats are likely to suffer the consequences. Through effective cyber security planning and continuous monitoring of cyber threats, a business can protect itself from what is cyber crime.
