Knowing when to include agents into your vulnerability management processes isn't an easy decision. Below are common use cases for agent-based vulnerability scanning to assist you build out your combined scanning strategy.
Intermittent or Irregular Connectivity: Vulnerability management teams are now tasked with scanning devices that access the company network remotely using public or home-based Wi-Fi connections. These connections are often unreliable and intermittent leading to missed network-based scans. Fortunately, the scanning frequency of agents doesn't require a network connection. The agent detects when the device is back online, sending scan data when it's ready to communicate with the VM platform.
Connecting Non-Corporate Devices to Corporate Networks:With the increased use of private devices, company networks are more exposed to malware and infections thanks to limited IT and security teams' control and visibility. Agent-based scanning gives security teams insight into weaknesses on non-corporate endpoints, keeping them informed about professional hacker is potential attack vectors in order that they can take appropriate action.
Endpoints Residing Outside of Company Networks: Whether company-issued or BYOD, remote assets frequently hook up with the web outside of traditional network bounds. An agent that resides on remote endpoints conducts regular, authenticated scans checking out system changes and unpatched software. The results are then sent back to the VM platform and combined with other scan results for review, prioritization, and mitigation planning.

Explanation
A pharming attacker tries to send a web site's traffic to a faux website controlled by the offender, typically for the aim of collection sensitive data from victims or putting in malware on their machines. Attacker tend to specialize in making look-alike ecommerce and digital banking websites to reap credentials and payment card data.
Though they share similar goals, pharming uses a special technique from phishing. "Pharming attacker are targeted on manipulating a system, instead of tricking people into reaching to a dangerous web site," explains David Emm, principal security man of science at Kaspersky. "When either a phishing or pharming attacker is completed by a criminal, they need a similar driving issue to induce victims onto a corrupt location, however the mechanisms during which this is often undertaken are completely different."
