“AI can attack at scale, which is unprecedented. It can also attack with velocity, and therefore you need technology tools to counter that speed and volume capability that attackers have,” said Gaurav Agarwal, Vice-President of Technology for IBM India and South Asia, explaining how artificial intelligence (AI) is reshaping cybersecurity threats and what organisations must do to address them.
When people worked in offices and accessed company applications from controlled environments, protecting those systems was straightforward. Companies could set up a security perimeter, and it worked. For the uninitiated, perimeter security in cybersecurity stands for a digital wall or block that keeps hackers out of an organisation’s network. According to Agarwal, however, the shift to cloud services, remote work, and AI agents is forcing organisations to rethink traditional perimeter-based security models.
“Now, with applications going to the cloud, people accessing these from anywhere and everywhere, perimeter security protection does not hold true anymore,” Agarwal explained. This shift means that traditional firewalls and network boundaries are no longer enough. Instead, a new security frontier has emerged, which is, identity itself.
The new attack vector
When employees and systems access applications from anywhere using any device, attackers have found an easier way to make an inroad to steal credentials. Once they have valid login credentials, they look like legitimate insiders to the system. “Public-facing applications and use of valid credentials were the top two access vectors that led to this problem,” Agarwal says, citing IBM’s Threat Intelligence report.
