No computer network can be protected 100% of the Internet threat that can bring and the attacker. But with smart IT security policies and use layered approach, you can reduce your risk for attack.
The virus is more mixed and has a payload higher than the previous. This means they are easier to distribute and can do greater damage. The virus can attack the network even at the lowest level, which means they can ignore the desktop and server antivirus software. Antivirus software does not provide complete protection is not.
So what’s a layered network security and antivirus software, and how should you approach? Simply put, as the defense put barricade on each routes may go to your network. A typical layered antivirus solutions will include the server AV, AV desktop, gateway AV, AV email, and some type of intrusion detection / prevention services (IDS, IPS).
This approach will not only protect from the threats that come in the computer and the file system level, but will also protect you from the resistance network and other network level of service attacks.
A layered approach also helps provide efficiency and load-balancing on your network. If you find that you get your mail servers pounded daily by viruses or phishing emails, and then have a gateway antivirus software can help take some burden off of your mail server to stop with those who never reach the mail from the server.
It also provides greater security on the desktop using the gateway antivirus software. If users try to download the virus to their computer, rather than letting the desktop AV software to handle quarantine / deleted, the gateway system will build a streaming package as a virus scan and pass. If this condition is the same virus that is known signature, then interrupted by a stream and the virus is not the gateway to the desktop to begin with.
Protecting your network with a layered approach is not only the design for network security company, it is necessary for all business network.
