Cybersecurity, computer network security or digital information security is the overall protection of computer networks and systems from unauthorized access, information theft, loss of or damage to their equipment, software or computer data, and from the interference or misdirection of their services. This includes protecting corporate and private network systems from hackers’ attacks and intrusions, in order to safeguard companies from malicious external activity which could potentially harm their computer systems. It also involves securing data for recovery or fixing any damages that may have been caused by viruses, malware or any other attacking computer code.
There are many ways in which a company can be targeted for protection through the use of cyber security tools and services. Common methods include spear-phishing, distributed denial-of-service (DDoS) attacks, buffer overruns, and keylogger infections. spear-phishing involves sending spoofed emails that appear to be from legitimate companies or sources, which may then get into the inboxes of targeted users. These emails contain advertising links that when clicked result in loading malicious codes on the system.
One of the most important roles of a cyber security analyst is to analyze any new vulnerabilities or attacks that may arise and work to resolve them before they are exploited. While there are many outside threats that are categorized as cyber security attacks, internal attacks on companies’ computer systems are comparatively rare. A good example of an internal attack would be a virus attacking a company’s database.
Endpoint security is another aspect of cyber security that is often overlooked. The goal of end-point security is to prevent unauthorized access to a computer system through the Internet, including the possibility of attacks from various locations on the Internet. In many cases, an organization’s network infrastructure is the source of its vulnerability. Companies must therefore work to prevent or limit the damage if such a vulnerability is made public. Endpoint security techniques include various layers of protection, including firewalls, software restrictions, encryption, and more.
Prevention is often the best practice for combating cyber security risks. Businesses must implement strategies aimed at scanning their computer systems for known security risks, developing policies to deal with those risks, and regularly monitoring and assessing those policies. Good cyber security analyst service will work to mitigate the risk by identifying what changes could be made to the system that would decrease the risk. This includes identifying and removing known vulnerabilities.
While prevention is the best practice for stopping cyber security attacks, there are instances where a response is necessary. When a cyber security attack occurs on a critical system, the United States Cyber Command was mandated to respond by launching cyber strikes against the attacker’s computer servers. In the case of attacks on U.S. soil, the Department of Homeland Security is required to respond by coordinating a cyber response through the Department of Defense. While cyber security analysts can minimize the risk of such attacks by detecting them early, it may be impossible to completely prevent them from happening.
As the field of cyber security analysis has grown, so has the need for qualified cyber security analysts. Qualified workers are needed in a variety of positions. Some positions require that the person have a bachelor’s degree in information technology or a related field, while others only require a high school diploma. Many employers are interested in candidates with at least a bachelor’s degree in computer or information technologies, as these are the people most likely to be responsible for cyber security analysis.

A cyber security analyst should also have good writing skills. It is not uncommon for these individuals to write detailed reports on an assignment, and they often must present findings to management in a timely manner. Those who have completed formal training in information technology security may choose to specialize in this field by focusing their studies toward the field of information technology security. A number of specialty options are available, including programs focused on software security, network security, configuration management, testing, and security testing.
