A number of prevention techniques that have existed for years remain fundamental components of any modern security program.

From worms and viruses to massive distributed denial-of-service attacks, the sophistication, scale, and impact of cybercrime has evolved significantly in recent years. For that reason, cybersecurity has made its way to the top of boardrooms' risk management agendas as CEOs and senior management teams assess how to best respond to and mitigate cyberthreats. Following the 9/11 attacks in 2001, firms around the world turned their attention to enhancing physical security as part of a commitment to mitigating risk. At the time, many organizations established vast data centers to protect against the loss of company data and to ensure the continuity of business operations in the event of an incident at one of their physical locations. 

Fast forward to the present day, and innovative information technology solutions are once again contributing to robust risk management programs, specifically around the ability to prevent and combat cyberthreats. These solutions have been complemented by the growing practice of sharing cyberthreat intelligence across organizations globally, which has further enhanced the ability for rapid response in the case of a successful network infiltration by malicious actors.

But while new defense technologies to obstruct cyberthreats are innovative and often helpful, there are a number of prevention techniques that have existed for many years that remain fundamental components of any modern security program.

First, the tracking and understanding of a firm's internal IT traffic remains critical in minimizing cyberrisk and responding to cyberthreats in a timely manner. In fact, many firms are beginning to move away from focusing solely on protecting their perimeter, having realized that even the most sophisticated solution can't stop all malware from entering an environment. As such, firms are turning their attention to analysis-led cybersecurity strategies focused on internal data movement. This internal analysis is highly effective in revealing abnormalities that point to cyberthreats and provide useful cyberthreat intelligence.

Second, the widespread use of cyberthreat intelligence across firms and critical industries can improve cyber defenses by enabling collective action, a strong complement to individual in-house security measures. Cybercriminals are known to share their attack techniques and learn from each other. The same should be true of targets. Automated sharing of cyberthreat information can help organizations across the globe to identify and respond to a network infiltration because malicious actors often use the same method to attack more than one target.

Third, firms need to realize that guarding against cybercrime is a company-wide responsibility. A large number of serious system breaches arise from something that may seem harmless, such as opening an email attachment or a link sent by an unknown sender. While the internal analysis-led approach can be helpful in this area, robust enterprise-wide cybersecurity plans ensure maximum protection against cyber attacks, irrespective of the individual knowledge base of employees.

Ultimately, firms should remember that despite the rise of new latest cybersecurity innovation, they need to get the basics right first. Those critical tools established some 20 years ago remain the foundation of any successful cybersecurity program. Opting for new technology solutions alone and underinvesting in core competencies and the basics, such as segregation of internal systems and monitoring internal data movements, may prove counterproductive at a time of growing cyberthreats.
