Publisher Summary Some universal security countermeasures are supposed to be implemented, regardless of whether one is an individual or a Fortune 500 company. Without these issues, one leaves himself widely vulnerable to trivial attacks. This chapter provides golden rules for information security as seen by the author. Taking responsibility, is the most important rule of all. One needs to accept responsibility for what one has control of. Security must be considered a part of all operations. Probably the most critical aspect of taking responsibility is that one needs to develop common knowledge. The most common computer-related attacks are viruses. All Windows-based PCs and Macs need to run anti-virus software. Anti-virus software does not stop all attacks against a computer. Viruses are essentially computer programs that are placed on a computer to perform bad actions. There are attacks that target the software that runs on a computer. A software can either be misconfigured or have vulnerabilities built into it. Personal firewalls intend to prevent remote threats from exploiting those vulnerabilities, among others. Anti-spyware needs to be allowed to update itself, as well as renewed annually. Anti-spyware is frequently bundled with security software suites.
