Gajshield's Data Leak Prevention

Data Leak Prevention

Data volume has been growing exponentially, dramatically increasing opportunities for theft and accidental disclosure of sensitive information. By 2020 the digital universe — the data we create and copy annually — will reach 44 zettabytes, or 44 trillion gigabytes. This reality, along with increases in the portability of data, employee mobility and penalties for failing to comply with strict data protection regulations such as the EU GDPR and New York Cybersecurity Requirements raise the question: “What more can organizations do to protect themselves and their stakeholders?” An integral part of the answer is data loss prevention (DLP).

Numerous examples of accidental and deliberate data leakage continue to make headlines and data leak prevention (DLP) technologies are being touted as a panacea. Unfortunately, given the scope, size, and distributed nature of most enterprise datasets, just discovering where the data is and who owns it is a challenge. For most organizations, controlling the applications most often used to leak sensitive data and stopping unauthorized transmission of files, credit card and social security numbers and their ilk would be acceptable. Many organizations would like to monitor the files uploaded by their employee and then have control to block such uploads. Exerting that control at trust boundaries is ideal – whether the demarcation point is between inside and outside, the firewall sits on the perfect spot, seeing all traffic.

GajShield's Enterprise Cloud

Cloud banner

As mobile work scenarios increase, secure data communication surpasses traditional network security solutions. Furthermore, most of the organizations have a decentralized structure where, often several individuals are responsible for business decisions. Organizations with decentralized structures have multiple distributions. These distributions have different kind of users like branch users (2 to 5 users per branch), store users (single systems connected to the internet), sales or marketing executives which are roaming users, etc. If we consider Road-warriors itself, there are multiple risks associated with them. Road warriors may use laptops for communication while roaming outside the network which itself poses so many risks relating to the company’s data or information. Though enterprises provide end-point protection, they do not take necessary steps to secure their network gateway. Road warriors or roaming users further exacerbate this problem with their access to the Internet often bypassing all security controls.

GajShield’s Enterprise cloud aims at tackling all these problems by providing a comprehensive solution targeting all the types of users by enforcing risk mitigation and policy enforcement through its next generation firewall appliance.

What is a firewall? How does it work?

What is a firewall? How does it work?

A firewall is a system or group of systems that enforces an access control policy between two networks. The actual means by which this is accomplished varies widely, but in principle, the firewall can be thought of as a pair of mechanisms: one, which exists to block traffic, and the other, which, exists to permit traffic. Some firewalls place a greater emphasis on blocking traffic, while others emphasize permitting traffic. Probably the most important thing to recognize about a firewall is that it implements an access control policy. 

Types of Firewalls
Following are the types of firewalls based on how they work:

  • Packet Filtering Firewalls - that block selected network packets.
  • Proxy Servers - that make network connections for you.
  • Unified threat management (UTM) firewall - A UTM device typically combines, in a loosely coupled way,
    the functions of a stateful inspection firewall with intrusion prevention and antivirus and simple malware
    detection. It may also include additional services for content filtering. 
  • Next-generation firewall (NGFW) - Firewalls have evolved beyond simple packet filtering and stateful

Why the Future of Firewall Security will be Context Based?

Future of Firewall Security is Context based

Rise in adoption of mobile, social and cloud technologies has created the need for a more proactive and context-based approach to managing firewall security

For years, business organizations followed a rather reactive approach to managing IT firewall security. Every time there was a new type of attack, security vendors would come up with a new solution to combat that threat. This approach worked very well till users accessed computers in controlled work environments. The company could easily monitor incoming and outgoing network traffic. But in today’s multi-channel environment, where users stay connected through a plethora of mobile devices and web-based apps, the security threats and vulnerabilities have only increased. According to PWC’s Global Information Security Survey 2015, the number of security incidents detected in 2014 was 48% higher than the previous year.

Multiple access devices and touch points have given hackers more options for entering corporate networks, without being easily detected. Therefore, the traditional models of security management are proving insufficient. There is a need to adopt a new approach to managing security - one that is more proactive, sensitive and context-based.

GajShield Next Generation Firewall: Intelligent Security

Intelligent Security

All traffic pass through a security device, it is expected that current firewalls inspect this traffic and provide indepth analysis of its usage. GajShield Next Generation Firewall is built with intelligent reporting system which enables an organisation to quickly identify mis-use and take quick decision on whether bandwidth needs to be upgraded.

Productivity graph

From broad level classification of traffic from Business, to Productivity Loss, it brings in intelligent labeling to traffic. With a first glance, network administrators can make intelligent decision on whether to increase the bandwidth or control it use. With detailed report on which users is using what application, site to misuse traffic, it is easy to manage traffic and improve performance of business application.
