Computer security, cybercrime or data security is the prevention of computer systems and/or networks from unauthorized access, loss of data, malicious intervention or alteration of their internal functions or services, and from the intentional disruption or misuse of their services. It also involves the monitoring and management of such systems and networks to prevent unauthorized access, to ensure security and to ensure the integrity and efficiency of a system or network, and to implement detection, blocking, and removal of security vulnerabilities that may be exploited by attackers. There are various forms of computer security; common ones include content filtering, email filtering, antivirus protection, firewall, and intrusion detection and response. While the prevention of security vulnerabilities is often achieved by using common methods like firewalls and anti-virus software, there are instances when these measures may not be enough to thwart hackers.
A number of latest technologies like Web hosting, e-mail hosting, remote access and file sharing have made the task of defending a company’s network easier and more convenient. However, it is important for businesses to understand the different forms of attacks on their computers and the latest trends in the field of computer and cyber security to prevent or minimize the impact of such attacks. It is also important for businesses to consider the importance of an integrated security solution that combines traditional security measures with advanced technology to effectively defend a business from different forms of attacks and to protect against the sophisticated threats that hackers and other security threats bring. This way, by applying different types of security measures, a business can more effectively prevent attacks and minimize the impact of such attacks.
Many companies, government agencies and even specific groups such as the National Cyber Security Division (NCS Division) of the Department of Homeland Security (DHS) have been created to address and combat the issues related to cyber threats. Many federal agencies have published technical manuals and white papers on how to detect, analyze and respond to cyber threats. Some states, cities and countries, such as California, Connecticut, Illinois and New York, have also developed their own plans and guidelines for combating cyber crimes and securing cyberspace. The public and private sectors are also engaging in different types of research and development activities related to combating cyber threats. These initiatives are helping businesses and organizations develop the knowledge and skills they need to strengthen their defenses against cyber threats and prevent and mitigate damage caused by cyber attacks.
