A marked reduction in ransomware attacks last year seemed to signal that security teams and law enforcement officials had turned the tide against their cyber adversaries. That optimism was premature. The first half of 2023 has seen record numbers of ransomware attacks featuring much larger ransom demands, shifting data targets, and frequent use of double- and triple-extortion tactics.
Malicious actors have weaponized artificial intelligence to launch attacks with unprecedented scale and frequency. In response, more organizations are fighting fire with fire by leveraging AI and machine learning (ML) to enhance their detection, prevention and response capabilities.
The Internet facilitates a great deal of business activity around the world by enabling communication and data exchange across network boundaries, effectively creating a global marketplace. However, transmitting sensitive information across the public Internet always carries a risk of exposure, which is why most organizations rely upon virtual private networks (VPNs) to create secure connections.
The firewall is an essential first line of network defense, filtering traffic and blocking malicious outsiders from gaining access to your critical systems. Businesses today commonly use multiple firewalls to create a system of protected network segments with varying security needs. In this post, we’ll take a brief look at five primary types of firewalls and the three main implementation models.
