Cybersecurity, computer forensics, or computer-related security is the prevention of information systems and networks from theft, damage or disclosure of their computer programs and data, and from the misdirection or interruption of their services. Cybersecurity professionals work in the detection, prevention, and response to security threats. They can detect vulnerabilities in networks and information systems that may be exploited by hackers or other malware. The prevention of security breaches involves the identification, prevention, and response to security threats. Security professionals can also test the security of a network.

A variety of threats are faced by businesses today. Businesses need to consider how they can protect themselves against external threats as well as internal threats. Many companies now face threats from hackers who may obtain company secrets through hacking, or may infiltrate systems and use information to gain access to computers and consumer information. These attacks may be executed through a vulnerability found within a business’s network or a vulnerability found outside of the network. In addition, many hackers target companies that rely on networks for their own security measures.

As technology advances, more businesses will need to hire an IT professional to assist them in maintaining their networks. An IT professional works to prevent cyber attacks and help businesses protect themselves from outside intrusions by implementing solutions for security testing and prevention, along with tools to help administrators secure their networks. These professionals work to address the latest threats and devise the best methods of implementing IT security measures to keep customers and their data safe.
