Attack surface

Securing the expanding attack surface

Keeping the attack surface to the minimum is an effective measure of web application security, but also a complex one. As organizations continue to engage in digital transformation by adopting new technologies, their IT environments and available attack surfaces greatly increase. The popularization of APIs, commonly used to interface with third party service software, unavoidably augment the attack surface. IT security professionals must continuously grapple with a growing number of sophisticated threats and attacks originating from multiple attack vectors. While minimizing the attack surface area to limit the likelihood of attack is important, one must not forget to secure the remaining exposed attack surface.

Your challenges

The first challenge is to understand the attack surface. The potential attack vectors are burgeoning due the end of the perimeter security and the accelerating rate of digitalization and the reliance on communication technologies. Without adequate security measures, hackers are more likely to succeed in stealing data, denying service or damaging company IT systems. The countless potential vulnerable points each enterprise has are all a playing field for a malicious hacker, especially when communication spans across employees, partners, customers and suppliers. And any one vulnerable point can lead to an attack. Visualizing the security landscape and finding indicators of exposures, such as missing security controls in systems or software is challenging and must be done without risking business disruption. Actively searching for vulnerabilities can be time consuming, hence some level of automation is crucial. Secondly, any sign of compromise must lead to a prioritized action that can immediately reduce risk across the entire organization.
