The optimum goal of every person using a PC and spending time on the internet should be that they are operating in a safe and secure environment. At least that is the conceptual ideal behind computer security. Attaining such an ideal is only possible when you have the 3 basic processes of computer security in place. These are as follows:
- Prevention – The function of prevention typically employs numerous safeguards, the three most common being Cryptography, Firewalls, and User Account access controls. Firewalls protect from unwanted attacks while Cryptograph and User Account access controls protect system data and files.
- Detection – Intrusion Detection Systems (IDS’s) were designed and developed to detect attacks on one’s network as they were happening, as well as assisting in “post-attack forensics”. Typically the use of audit trails and logs enable the user to monitor their system more closely.
- Response – This is defined based on an individual system’s requirements. These requirements are initially assessed up front in order to determine what avenue of response to pursue. It covers a broad range of response classifications and methods such as counter-attacks, notification of legal authorities, and upgrades to system protection.
There are times when complete destruction of the infected system is recommended since all of the compromised components and resources may not be detected, leaving no choice in the matter.
Most computer security today is founded in the preventative process (rather than the other two) such as the use of a Firewall or employing a particular “Exit Procedure.”
