Network Security

Organizations spend huge resources in analyzing and adopting internet based business models, resulting in new sources of revenue, optimized and efficient business process and gaining the competitive advantage.

But Internet connectivity without appropriate security measures can compromise the very gains in productivity that makes today’s organizations more profitable. In the past, security threats from external sources were slow-moving and easy to defend against. Intrusions were not that difficult to ward off but with an increased trend in unique and sophisticated methods of attack security has become a huge concern for enterprises. In today’s connected environment, outbreaks spread across the world in a matter of minutes or even seconds, and security systems must react instantly to prevent a potential disaster.

More About Network Security

Increasingly, security attacks mostly target browser-based business applications. Because these dynamic, complex custom applications may not have antivirus signatures or regularly available application patches, one breach in security can expose assets, trigger legal liability, severely damage customer confidence, and negatively affect profitability. Hence having an effective security policy, updated regularly whilst also having physical monitoring of critical data resources is very important.

Seven IT Technologies offers a self-defending network that uses the network to identify, prevent, and adapt to threats from internal and external sources. It simplifies the security environment through tight integration, comprehensive security, increased end-to-end visibility, and improved total cost of ownership. All components of the network – the secure network platform, advanced services and technologies, and operational management and policy control– play a part in securing the networked environment.

UTM

UTM is just another name for an all in one security appliance. A UTM appliance will consist of a firewall as well as other key security features such as spam filtering, web filtering, anti-virus, anti-spyware, anti-phishing, IPS/IDS, DOS and DDOS protection, Application filtering, Network Access Control, VPN’s and so on.

When the use of internet started rising and become an everyday need for many businesses and companies, so did the concerns for network security. This is when traditional firewalls and anti-virus packages became a mandatory need. As the years have rolled on, firewalls and anti-virus still very much at the heart of network and internet security have become just part of the solution. A firewall will filter on ports, protocols and connection states. If allowed, the traffic will filter through, and if denied the traffic is dropped. An anti-virus scanner will scan for viruses and either quarantine or delete if found. Following are features of UMT:

• IPS/IDS
• Anti Virus
• Zero Day Protection
• URL Filter
• Spam Filter
• Anti Spy Ware
• Application Control

Next Generation Firewall and IPS

A Next-Gen Firewall provides application control and visibility and comes built in with a list of thousands of applications defined by application signatures which you are able to control and write rules for. A Next-Gen firewall provides the ability to create rules based on who the user is or which group it belongs to and to what applications (based on application content signatures and no longer just the port number) they have permission to use across the firewall and optionally to where they are allowed access. For example the IT department are allowed to FTP on to the DMZ servers, and everyone else is blocked.

Next-Gen firewalls generally come with utilities that provide better visibility in relation to users and applications. So for example many vendors have introduced dashboard widgets on the home pages which show information such as top 20 users using peer to peer applications, top 10 applications used over a period of time and so on. Also granular reporting capabilities have been built in to include user names and applications, and other utilities such as real-time traffic flows have been introduced.

An NGFW is capable of:

• IPS/IDS
• Anti Virus
• Zero Day Protection
• URL Filter
• Threat Management
• Anti Spy Ware
• Application Control Upto Layer 7
• User Identification
• Content Awareness
• VPN
