In the early years of cyberattacks, organizations would wait to be attacked before they developed a comprehensive plan and response to the attacker. The attack would render the organizations’ network presence useless and down for days. Several reasons cyberattacks could severely cripple a network in the early days of this malicious behavior are not enough concentrated research on defending and preventing and the lack of a coordinated effort between private industry and the government.

Since the first well known and wide spread cyberattack in the mid-1990’s, many professionals in public and private organizations have diligently been studying and working on the problem of cyberattacks. Initially security companies like Norton, McAfee, Trend Micro, etc. approached the problem from a reactive posture. They knew hackers/malicious attackers were going to strike. The goal of what is now called Intrusion Detection Systems (IDS) was to detect a malicious attacker before an anti-virus, Trojan horse, or worm was used to strike. If the attacker was able to strike the network, security professionals would dissect the code. Once the code was dissected, a response or “fix” was applied to the infected machine(s). The “fix” is now called a signature and they are consistently downloaded over the network as weekly updates to defend against known attacks. Although IDS is a wait and see posture, security professionals have gotten much more sophisticated in their approach and it continues to evolve as part of the arsenal.
Security professionals began looking at the problem from a preventive angle. This moved the cybersecurity industry from defensive to offensive mode. They were now troubleshooting how to prevent an attack on a system or network. Based on this line of thinking, an Intrusion Prevention Systems (IPS) called Snort (2010) was soon introduced. Snort is a combination IDS and IPS open source software available for FREE download. Using IDS/IPS software like Snort allows security professionals to be proactive in the cybersecurity arena. Though IPS allows security professionals to play offense as well as defense, they do not rest on their laurels nor do they stop monitoring the work of malicious attackers which fuels creativity, imagination, and innovation. It also allows security professionals that defend the cyberworld to stay equal or one step ahead of attackers.
Cybersecurity also plays an offensive and defensive role in the economy. In its cybersecurity commercial, The University of Maryland University College (2012) states there will be “fifty-thousand jobs available in cybersecurity over the next ten years.” The school has been running this commercial for more than two years. When the commercial first began running they quoted thirty-thousand jobs. They have obviously adjusted the forecast higher based upon studies as well as the government and private industry identifying cybersecurity as a critical need to defend critical infrastructure.
