Security

             Security is the discipline of using effective protection measures to safeguard important assets from abuse. In other words, "security" is about protecting important things. Protection involves not just mechanisms (such as locks and doors), but also proper selection and use of mechanisms.
             Properly applied, the various disciplines of information security really come down to risk management that is not fundamentally different from risk management in other situations such as finance and insurance.
             In learning how to think constructively about managing risks, often the following common sense vocabulary is used:
             Asset: something important that needs protection
             Risk: likelihood of threat leading to actual abuse
             Cost (1): reduction in value of abused asset
             Cost (2): amount of resources required to use security measures to protect an asset
             Benefit: the value of a security measure
             It would be great if these terms – asset, value, threat, risk, cost, benefit – could be used scientifically, but when it comes to information systems, most of them are pretty squishy. Nevertheless, even a "best guess" is remarkably useful. If guesses about relative value and likelihood are consistently applied, then it is usually possible to decide on the priority of potential improvements in information security.
             Cost becomes a matter of budget. Most people with authority over funds for security can, if properly informed, make good decisions about how to allocate the budget. In many instances, it is possible to analyze whether the incremental value of a high budget would be significant.
             Understanding of information security technology is necessary to make informed judgements like these. Fortunately, the essential technological aspects are not rocket science.
             There are several types of security issues: data security, computer security, system security, communication security, and network security. The te...
