System Security professionals are experts on preventing and mitigating security breaches that may arise from vulnerabilities in computer systems. This field covers a range of areas of expertise, including information security, network security, and mobile security. System Security professionals must “think like a hacker” in order to anticipate the main vectors of likely attack by malicious outsiders. They should have a keen eye for the most minute details, plus a well-rounded and in-depth knowledge of computer systems and the the tools of the trade.

There is a shortage of formal training available to those who wish to go into the security field. While a formal education in computer systems is desirable, many of the best security experts are self-taught hobbyists when it comes to their familiarity with “hacking” and the techniques and vulnerabilities exploited by attackers. Since your security expert will be intimately aware of all of your system’s weakest points, it is critical that you can trust him or her.

This article provides a sample System Security Expert job description that will help you write the perfect job ad, and ensure that you find and hire the person that matches your specific criteria.
