Network CyberSecurity

Internet connectivity today has become more important than ever before for all organizations. One of the top priorities for the organizations these days is to provide unremitting, redundant and resilient internet connectivity to its user community. There are many reasons for such profound internet dependency, for example tremendous growth of SaaS, PaaS, IaaS based services, IOT and evolution of cloud hosted data and applications, to name a few.

Where internet provides such incredible opportunities for collaboration, instant exchange of data, and global connectivity, it also entails many perils. The inherent risks attached to internet leads the organizations to fervently protect their internet traffic. This is where the whole Cybersecurity effort comes into picture. Cybersecurity is a very broad term and can entail numerous security technologies and solutions. One of them is Internet Security at the network layer.

Network Security, itself has become an umbrella of multiple technologies that addresses different security concerns such as:

Layer 7 Firewalls:

These devices have become much more advanced compared to their predecessor devices. These firewalls allow/block traffic at application layer compared to legacy devices which worked at Layer 3 or 4 of OSI. This allows greater visibility and control of applications

Intrusion Prevention Systems (IPS):

IPS at network layer not only passively detects threats but also actively blocks them. IPS systems are also very effective at detecting and preventing Day 0 threats. IPS systems utilizes threat signatures, which are continuously updated by different security vendors to dynamically stay up to date and prevent/block any threats.

DNS Security:

One of the first protection mechanisms that can be deployed against Internet traffic is to deploy DNS Security. This inspects and blocks threats using DNS and prevents even the initiation of the traffic.

Malware Inspection:

Malware inspection system monitors and blocks any software that has malicious code such as viruses, worms, Trojans, ransomware, and spyware.

Web Security:

Web security solution will allow, detect and block user’s web only traffic based on the categories of application, threat levels and rating of the websites. These devices can also be utilized to perform SSL decryption for the encrypted traffic in order to perform deeper inspection.

Network Segmentation:

Network Segmentation allows sensitive or critical traffic to be isolated from non-critical traffic at network layer and provide different levels of access such as segmenting Corporate Traffic from Guest Traffic

There are many other network security solutions such as Wireless Security, VPN Security, Email Security that can be deployed these days in combination with above tools to provide a comprehensive security for internet traffic at the network layer.

Our Network Security Team always starts at understanding the business operations and its objectives, then analyze the current security mechanism in place and identify security gaps. Finally we devise a plan that will be customized to the customer needs and aligns with their overall business vision.
