Step by step: technologies and strategies against spyware threats

Spyware is terrible, and its threats are serious and disturbing IT staff. Protection of enterprise security environments requires highly professional anti-virus technology to protect all login points. Advanced kernel-level defense functions should also be required to completely prevent future spyware threats.

Peripheral blocking: Gateway Protection

To protect multiple logon sites from dangerous spyware attacks, the company's network must adopt multi-layer Anti-Spyware policies, including peripheral defense, related remedial measures and defense components. A gateway application can act as the first line of defense of a Network. It provides real-time protection on the periphery. To protect the network environment, the first step to prevent spyware is to block it from the perimeter of the network before it passes into the desktop workstation. To this end, the anti-spyware solution should be integrated into the gateway on the network. Real-time anti-spyware solutions can scan network communication in real time, search for suspicious programs, files, and data transmission that shows the characteristics of known spyware. Immediately after detecting spyware, send a notification to prevent the threat.

Defense first: two technologies

Today's spyware design has reached a very high level. One of the important performances is that it is difficult to clear it after it succeeds, therefore, using advanced defense technology is a crucial component in the battle against spyware. Some anti-spyware can scan the existing spyware in the system. This reactive passive response mechanism means that the spyware has been installed before it is cleared, the problem with this method is that many forms of spyware are hardly deleted after installation. Active Defense methods can effectively suppress fraudulent applications that attempt to rewrite system files or desktops in real time, thus completely blocking installation.

Generally, there are two types of spyware defense technologies: one is the rotation detection technology and the other is the real-time detection technology. The latter is a more advanced technology because it can provide protection at all times and consumes very little resources.

The rotation detection technology cannot effectively block spyware before the spyware starts. This technology is an unreliable way to defend against spyware infections. It is designed to regularly or periodically check the system and respond only when the spyware starts a process. In this way, spyware infection only occurs when such a scheme confirms malicious code.

Contrary to the rotation detection technology, the advantage of the real-time detection technology is that it is blocked at the kernel level before the spyware process has the opportunity to start. Real-time Monitoring means that the system has been "aware" of every process and can continuously prevent malicious code execution. Before spyware writes data to a hard disk, it intercepts and destroys malicious activities. The real-time detection method provides kernel-level protection, it can proactively and proactively prevent spyware installation to the desktop from the very beginning.

Final: Desktop Protection

Due to its characteristics, spyware infection is almost inevitable. Therefore, implementing remedial measures to address post-infection problems is equally important for defense threats. Administrators can remedy the problem by scanning existing spyware installed and isolating it within the computer. If you isolate all the code that has been inserted by spyware, they cannot establish a link with its external source. This policy relies on the fact that Spyware already exists on computers before security measures are taken.

Desktop solutions are equipped with remediation and defense components to clear existing spyware instances and defend against access through insecure Internet (such as through personal laptops or USB storage devices) attack.

Combining remediation and defense capabilities into independent desktop anti-spyware applications can prevent risks associated with spyware infections. Whether it is a corporate network or a home environment, the Desktop Protection scan function allows users to scan and clear spyware that already exists in the desktop. The preventive blocking function can also disable access to spyware on the desktop.

For enterprises and individuals, anti-spyware technology that provides complete remedial measures and defense functions is crucial for threat protection.
