Network stability is tightly connected with “high availability” and redundancy in links and device links. Single point of failure and misconfigured networks appliances can cause network downtime as well as network instability.

Network Security appliances like Firewalls and Intrusion prevention appliances are very important to protect networks from disruption, and unless these appliances are configured properly and network security policies and procedures are regularly maintained and implemented, your network could be still vulnerable.

Different types of network attacks have been implemented and developed throughout the years with different methods to prevent and hide from security appliances. Such threats include viruses, browser and application based exploits, DDOS etc. Usually these threats are either planted to gain remote or local access to specific information and data, or to stop a certain network service from working. Up to date network security procedures can prevent most of these attacks.

-By installing network security appliances to separate and scan all incoming and outgoing information to and from the organization.
-By keeping all software and operating systems patched and up to date at all times.

-By implementing a tight security policy throughout the network and performing regular checkups.

Most common attacks come from inside the network itself, usually enterprises and companies implement all kind of security measures on the edge of the network and leave the inside of the network wide open and vulnerable to attacks. Protecting the network from within is as important as protecting it from outside. And so, security appliances are added to separate and inspect network traffic to and from datacenter to ensure maximum protection.

VPN networks are very common nowadays, and almost every company has a VPN network to connect their branches across public networks such as the internet. Some of the protocols used for VPN traffic encryption are outdated and have been cracked and proven to be unsecure. In order to maximize the data confidentiality and security, companies should migrate to more recent security protocols and algorithms.

WAN optimization appliances have been proven to increase data transfer efficiency across WAN links while delivering business critical applications over WAN or VPN. These appliancies help eliminate the need for fast and pricy WAN links needed to reach a satisfying network application performance level.
