Computer Security Challenges

Computer and network security is both fascinating and complex. Some of the reasons follow:

• Security is not simple

• Potential attacks on the security features need to be considered

• Procedures used to provide particular services are often counter-intuitive

• It is necessary to decide where to use the various security mechanisms

• Requires constant monitoring

• Is too often an afterthought

• Security mechanisms typically involve more than a particular algorithm or protocol

• Security is essentially a battle of wits between a perpetrator and the designer

• Little benefit from security investment is perceived until a security failure occurs

• Strong security is often viewed as an impediment to efficient and user-friendly operation
