Businesses are often attacked by malicious viruses after accessing the harmful websites unknowingly. A small and inadvertent mistake like this can prove to be costly for your business. These security lapses or vulnerability get magnified when malware, phishing force a business to legal tangles and major financial loss. Hence, to protect the organizations from these risks, software and applications like web filtering, intrusion prevention system (IPS), content filtering are used to eliminate or reduce any intentional or accidental access to the harmful websites.

The answer to these online threats is to have an integrated web solution consisting of Anti-Virus, Anti-Spyware and IPS to have a thorough threat detection and prevention system in place.

The virtual security applications prevent the online threats through the following ways:

Monitoring The Network

Through the prevention/monitoring system, the entire network is verified for suspicious web traffic through detailed analysis of the protocol activities. The primary tasks of this monitoring process are to secure the confidentiality and accessibility of the network. After installing such monitoring system, a network is able to differentiate between good traffic and hostile traffic. Some examples of hostile traffic are worms, viruses, Trojans, third-party proxy, embedded URLs etc.

Wireless Network Scrutinization

By monitoring the wireless network, any unauthorized network access to a LAN can be prevented. This is done as an extension of the already available wireless LAN infrastructure. These systems can also be installed as a stand-alone process to comply with the no-wireless policies in an organization. This process authenticates the users of a corporate network and encrypts the authenticated/user data online. It establishes a secured Access Point (AP) to prevent any unsolicited bypassing.

Analyzing Network Behavior

Examining or analyzing the inflow and outflow of the traffic is an important aspect for strengthening the security of the network from harmful invasion on the servers, programs, applications, systems etc. This type of monitoring prevents the attacks such as denial of service, specific malwares, or any policy violations. Also, it enhances the overall efficiency of a network.

Preventing Intrusion Through A Specific Host

Virtual invasion can take place through a specific host by aggravating suspicious activities or events within its reach. The process of verifying a host helps protecting critical system data from harmful viruses. It monitors unusual occurrences beginning from the network layer to the application layer. Through this system, a list of trusted programs is maintained rather than detecting the virus patterns. Any occurrence that tries to bypass its permissions is blocked to prevent any potential threat. This process can also be used to run multiple security applications.

The modern web security process is being managed by various Unified Threat Management (UTM) appliances available both in hardware and virtual form. There are numerous firewalls that are based on packet filtering, circuit level relay, application proxy gateway, and these are also used for reducing SSL traffic latency, URL/Cookie hardening, SQL injection, cross-site scripting, session hijacking and so on. A professional subscription-based service with reasonable pricing can ensure that your business remains completely secured from these online threats.
