Blended Threats

Definition

A blended threat can describe one of two different scenarios. In the first, a blended threat refers to a multi-threat, or a combination of threat technologies into a single vector (e.g., a Trojan exhibits worm -like capabilities). In the second, a blended threat refers to a single threat that attacks via multiple vectors (e.g., a worm gains entry via email and then leverages back-door vulnerabilities for further infection and destruction). Blended threats are inherently malicious and spread rapidly.

These distinctions can be confusing. However, because of the nature and sophistication of today’s malware—and its creators—it is safe to assume that most contemporary threats are blended in one way, shape, or form.

How to protect your network, servers, pcs and mobile devices from blended threats

  • Implement a multi-layered Internet security protocol that provides protection at all entry points—including the Internet gateway, messaging gateway, endpoint clients, endpoint servers, and the network.
  • Implement both a network and a desktop firewall.
  • Keep all email, browser, and instant messaging security patches up to date.
  • Follow all additional guidelines to protect against Malware, Spam, Phishing, Spyware/Adware, and Crimeware.
  • Educate employees about the latest threats, symptoms of infection, and how to protect servers, PCs, and mobile devices. Refer to individual threat pages for specific recommendations: Malware , Spam , Phishing/Pharming, Spyware/Adware, and Crimeware.

What may happen if you don't adequately protect your technology assets from blended threats

  • Risk or propagation of denial-of-service (DoS) attacks
  • Exposure to broad range of additional malware threats
  • Loss of employee productivity due to network slowdowns, compromised machines, and diverted IT staff time to mitigate damage.
  • Potential loss of critical enterprise data and documents, which may result in intellectual property and/or identity theft.
  • Financial cost to mitigate and repair damaged equipment.
  • Damage to company image and bottom line.
