Types of Computer Security Threats and How to Avoid Them

Security measurement matters to every stakeholder in network security. It provides security practitioners the exact security awareness. However, most of the works are not applicable to the unknown threat. Based on the prediction, we propose a method of security measurement. In detail, we compute the optimal attack timing from the perspective of attacker, using a long-term game to estimate the risk of being found and then choose the optimal timing based on the risk and profit.

Computer security threats are relentlessly inventive. Masters of disguise and manipulation, these threats constantly evolve to find new ways to annoy, steal and harm. Arm yourself with information and resources to safeguard against complex and growing computer security threats and stay safe online. Perhaps the most well-known computer security threat, a computer virus is a program written to alter the way a computer operates, without the permission or knowledge of the user.

Cyber security professionals continually defend computer systems against different types of cyber threats. Cyber attacks hit businesses and private systems every day, and the variety of attacks has increased quickly. The motives for cyber attacks are many. One is money.
