IT Security

Security is essential for protecting assets, which include valuable items such as people, intellectual property, physical property, data, services, and reputation. These assets are exposed to threats, vulnerabilities, and attacks that can compromise their integrity and value. A threat is a potential action that could harm an asset, while vulnerabilities are weaknesses that allow threats to take action. Managing risk through thorough risk analysis is crucial to quantify threats and protect assets. Prioritize security to mitigate risks and ensure asset safety.
