# Spear-Phishing Attacks: Are They Preventable?
Phishing attacks are increasing at alarming rates. Surveys show that [71% of businesses](https://www.techrepublic.com/article/report-71-of-smbs-are-not-prepared-for-cybersecurity-risks/) are not prepared to manage these type of attacks. Many businesses are finding that their defenses are limited and people in the highest offices are vulnerable.

Security technologies such as firewalls are meant, at best, to prevent data security breaches, or at worst, detect them before they get out of hand; but in some cases, organizations have been complacent. In the infamous [Target data breach of 2013](https://www.wired.com/2014/01/target-hack/), hackers were roaming their system and stealing data for two weeks before the breach was even detected. In the equally [egregious breach of Heartland Payment Systems](http://it.toolbox.com/blogs/internet-security/heartland-the-greatest-network-breach-in-the-21s-century-53445) five years earlier, hackers were stealing data for several weeks before the invasion was discovered. Ironically, both Heartland and Target were PCI-compliant, but the time lag between system compromise and detection was unnecessarily long. And, they’re not alone in this regard.

## **Vulnerability Details**
This vulnerability affects an unknown function of the SSL VPN component within the ASA. The vulnerability is triggered when an attacker attempts to double free a section of memory when the VPN component is active on the ASA. An attacker could exploit this vulnerability by sending multiple, crafted XML packets to a webvpn-configured interface on the affected system.

## [Protect. Detect. Respond: The Case for Managed Detection and Response](https://email.networksgroup.com/protect.-detect.-respond-the-case-for-managed-detection-and-response)

Cyber security is on the mind of every business executive in the world. Modern security challenges are not easy to fix or even identify, and despite some misleading advertising from vendors, there is no one-size-fits-all solution. We frequently observe large visibility gaps in existing security implementations, providing even obvious red flags to slip under the radar. Firewalls and traditional antivirus software are important, but only react to known threats. Too many organizations rely on passive preventative technology for network security. Good attackers employ stealth and polymorphic tools that defy signature-based detection, allowing them to bypass these technologies all together. We must assume that *threats will get in*, and *no system is impenetrable*.

As global cybercrime continues to develop new methods to penetrate system defenses, the tactics used in response to threats have been forced to adapt as well. The result has been a move from simple antivirus protection to complete endpoint protection using sophisticated integrations of endpoint malware protection, threat detection and response algorithms, and, in some cases, managed security services. Endpoint threat detection has been identified by Gartner research as one of the top tools for fighting cybercrime.
