Application control and NGFW(next gen firewall)
When it comes to applications, NGFWs have a big advantage: because they are application aware, they can filter aberrant traffic and prevent intrusions, data theft, and malware insertion. However, security is only one element of the NGFW application narrative; the other parts are discovery and management.(next gen firewall)
Many firms are currently suffering chaos, at least in terms of application development. Email, for example, is no longer a basic store-and-forward application on a network. Today, real-time collaboration tools such as Web 2.0 apps, instant messenger (IM), peer-to-peer applications, Voice over IP (VoIP), streaming video, and teleconferencing have replaced traditional data transmission methods. Each of those applications, on the other hand, has become a possible attack vector.
Today’s businesses must supply important business solutions while simultaneously dealing with employee use of inefficient and frequently harmful (from a security standpoint) web-based applications. Prioritization of bandwidth is required for critical activities, whereas social networking and gaming applications must be throttled or totally disabled.
Furthermore, failure with security laws and regulations can result in fines, penalties, and the loss of business.
The matter is further complicated by the fact that most firms are unable to distinguish between what is acceptable commercial use of those applications and what is not. Furthermore, many organisations lack control over the programmes on their networks and are unable to account for what is operating. The credo of network security experts is to know what is running, who is using it, and if the usage is valid, and NGFWs are ready to help answer those questions while offering additional control and administration to secure corporate assets.
Defending against new dangers(next gen firewall)
For businesses, security and efficiency must go hand in hand. Legacy firewalls just don’t provide enough protection, and security appliances cobbled together create unacceptable bottlenecks — a prescription for disaster. Any slowdowns in firewall or network performance might decrease the quality of latency-sensitive and collaborative apps, lowering service levels and productivity. To make problems worse, some IT firms limit network security solution features to avoid network speed slowdowns.
Organizations are experiencing new challenges as a result of weaknesses in widely used programmes, which are worsened by the popularity of social networks and connectivity solutions, which have become a breeding ground for malware and an ad hoc home for Internet criminals. Simultaneously, businesses are increasingly relying on online blogging, socialising, messaging, films, music, gaming, purchasing, and email to engage customers, raising the stakes for those wanting to protect corporate assets.
Streaming video, peer-to-peer (P2P), and hosted or cloud-based services are now exposing enterprises to the risk of data leakage, infiltration, and disruption. Furthermore, those same applications not only pose a security risk, but they also use bandwidth and reduce productivity by competing with mission-critical applications.
The Benefits Of NGFW
NGFWs can help because they provide application intelligence and control, intrusion prevention, malware protection, and SSL inspection at multi-gigabit rates, and they’re scalable to accommodate the fastest networks.
Administrators can utilise NGFWs to govern and manage both business and non-business apps to improve network and user productivity, and they can scan files of any size across any port without compromising security or performance. We will not limited high-end NGFWs by the number of concurrent files or network streams, allowing infected files to pass undetected. Furthermore, NGFWs may apply all security and application control technologies to SSL encrypted traffic, preventing it from becoming a new infection vector in the network.
NGFWs are obviously the future of enterprise network protection, providing a unified mechanism for securing applications, users, and data by analysing what is actually happening on the network and applying necessary policies while simultaneously scanning for problems. The objective is to ensure that your NGFW can support all of your current applications while also being resilient enough to handle future use cases. Administrators should choose an NGFW that is scalable to their predicted network performance requirements, as well as one that provides network analytics and insight, as well as ease of setup and administration.
